9 Salesforce AppExchange Apps for SaaS Renewal and Usage Billing

Salesforce teams selling SaaS used to bill a flat fee per seat and renew once a year. That model is fading. More products now charge for API calls, credits, tokens or other units of use, and many contracts mix a committed subscription with usage on top. Salesforce usage billing has become a real operations problem, and the tools that handle it have changed quickly in the past 18 months.

This guide covers 9 Salesforce billing apps and packages in the AppExchange/AgentExchange ecosystem, including vendor-supplied Salesforce integrations. They support renewal management, usage billing or renewal forecasting. It explains what each one does well and where it stops. It also covers the changes Salesforce made to its own revenue products, because those changes affect every app on this list. The goal is to help RevOps and finance teams pick a shortlist they can test against their own contracts.

TL;DR

• Salesforce CPQ is no longer sold to new customers, and Salesforce’s own usage billing now sits in Agentforce Revenue Management, which Salesforce expanded through its acquisition of m3ter, completed on July 1, 2026.
• The 9 apps split into native packages that run inside Salesforce and external billing engines that sync with it. That choice matters more than any single feature.
• Nue, Certinia, Conga, JustOn and Frisbii run natively. Zuora, Chargebee and Maxio bill outside Salesforce and push data back in. Gainsight handles renewal forecasting rather than invoicing.
• The right Salesforce usage billing app depends on how your usage data arrives, how your renewals are priced and where finance wants the system of record to live.
• Test every shortlisted app with a real contract that includes a ramp, an overage and a mid-term change before you sign.

What SaaS renewal and usage billing require in Salesforce

Salesforce usage billing means turning product activity into accurate invoice lines tied to the contract the sales team closed in Salesforce. That sounds simple until you list the steps. Usage records have to be collected from the product, matched to the right account and contract, priced against the right rate, and summed for the billing period. That last part is called rating, and it’s where most billing errors start.

Renewals add a second layer. A renewal isn’t a copy of last year’s deal. It may carry a price uplift, a new commitment level based on actual usage, a co-terming date for add-ons bought mid-term, or a switch from one pricing model to another. Sales needs to see renewal opportunities early, and finance needs the renewed terms to flow into billing without retyping.

A working setup usually has to handle these jobs:

• Pull usage data from the product on a schedule or in near real time, and match it to the right account.
• Price usage against tiers, commitments, prepaid credits or overage rates.
• Create renewal opportunities ahead of the end date with the correct terms.
• Apply amendments such as upgrades, quantity changes and early renewals without breaking the billing schedule.
• Show invoice and payment status to sales and customer success inside Salesforce.

Why renewals and usage belong together

Usage data shapes almost every renewal conversation in a usage-priced business. If a customer used far more than their commitment, the renewal is a chance to raise it and lower the overage rate. If they used far less, the account is a churn risk, and the renewal may need a smaller commitment to keep them. Good SaaS renewal management depends on seeing that usage history next to the contract before the renewal opportunity opens.

That’s why Salesforce usage billing and SaaS renewal management work best in the same data model, or at least in systems that share clean data. When usage sits in a billing tool that sales never opens, renewal reps negotiate blind. When it shows on the account page, they can walk into the call with actual consumption and overage spend.

Standard Salesforce objects don’t do most of this on their own. That’s why SaaS companies either buy Salesforce’s own revenue products or add AppExchange billing apps that fill the gap.

Why Salesforce teams are rethinking their billing stack in 2026

Salesforce changed its own product line, and that change forces a decision for many teams. Salesforce CPQ moved to end-of-sale status in March 2025. Salesforce’s CPQ transition page describes it as end of sale rather than end of life, and it names Revenue Cloud Advanced as the successor. On that page, Revenue Cloud Billing is described as the product that covers usage rating, invoicing, payments and collections. Existing CPQ customers can keep running it, but new buyers can’t purchase it.

The second change is bigger for Salesforce usage billing. Revenue Cloud has been renamed Agentforce Revenue Management, and Salesforce acquired m3ter to add high-volume mediation, metering and rating capabilities to Agentforce Revenue Management. The acquisition closed on July 1, 2026. Salesforce’s announcement describes these as capabilities the acquisition will bring to the platform. In CIO’s deal coverage, an analyst noted that most enterprises still run CPQ and billing systems built for seat-based pricing. Their own products, meanwhile, are becoming more usage-heavy. That gap is exactly what Salesforce usage billing tools are meant to close.

Demand for usage-based pricing explains the urgency. A January 2025 survey of 100 SaaS companies by Metronome and Greyhound Capital found that 85% had adopted usage-based pricing in some form. Maxio’s 2025 pricing trends report, based on a Benchmarkit survey of hundreds of SaaS companies, found that hybrid subscription and usage models had the highest median growth rate, at 21%. The same report found that 73% of companies with usage-based pricing actively forecast variable revenue, which is hard to do without clean billing data in the CRM.

AI features are adding pressure. The same Maxio report found that 44% of SaaS companies now charge for AI-powered features, and 43% bill more often than monthly. Both trends push more variable charges onto invoices. A Salesforce subscription billing setup designed around annual seat renewals struggles once usage-based pricing appears on most contracts.

For a team on legacy Salesforce CPQ, the choice now runs 3 ways. You can migrate to Agentforce Revenue Management, move to a native AppExchange app, or connect an external billing engine. The apps below cover the last 2 paths.

Native packages vs connected billing engines

The most important difference between these apps is where billing actually happens. A native package installs into your Salesforce org and stores subscriptions, usage and invoices as Salesforce records. A connected engine runs its own billing platform and syncs selected data back to Salesforce through a package or connector.

Native packages give every revenue team one shared record. Renewal opportunities, usage and invoices sit next to each other without sync delays. The tradeoff is that heavy usage processing inside Salesforce can hit platform limits, so vendors often process events outside the org and write results back. Ask any native vendor exactly where rating happens. Among AppExchange billing apps, the answer varies a lot, and it decides how well the app copes as usage grows.

Connected engines handle volume well and often support self-serve signups that never touch Salesforce. The tradeoff is sync. Fields drift and records fail to update. Before long, teams start asking which number is right. Connected setups need clear rules about which system owns each field, and an admin who watches the sync logs. Salesforce subscription billing data that arrives late or half-synced is worse than no data, because people act on it.

How we picked these 9 apps

Every app on this list had to meet 4 tests. It had to support subscription billing or renewal management for B2B SaaS. It had to handle usage or metered charges, or in one case renewal forecasting that depends on usage signals. It had to install into Salesforce or connect through a vendor-supported package. And it had to show product activity in 2026, such as a recent release or published update.

AppExchange is now part of Salesforce’s unified AgentExchange marketplace, though many buyers still use the old name. This list covers Salesforce billing apps and packages in that ecosystem, including vendor-supplied Salesforce integrations. Some vendors on this list sell through a public listing you can install yourself. Others, such as Zuora and Chargebee, supply their Salesforce package directly to customers. Each entry notes how the app reaches your org, since that affects how you evaluate and upgrade it. Listing status also changes over time, so confirm it on the marketplace before you shortlist any AppExchange billing apps.

The list leaves out Salesforce’s own Agentforce Revenue Management, because it’s a core Salesforce product rather than a third-party app. It also leaves out pure payment apps that process cards but don’t rate usage or manage renewals. Those tools often sit next to the apps below, but they solve a different problem.

Native apps for usage billing inside Salesforce

These 3 apps keep quoting, subscriptions and invoices inside the Salesforce org. They suit teams that want Salesforce to stay the system of record for revenue, with Salesforce usage billing handled on the same records that sales and finance already use.

1. Nue

Nue is the most direct fit for SaaS companies that sell both subscriptions and usage. It runs as a managed package on standard Salesforce objects and combines CPQ, billing and usage in one product. Its pricing options include credit burndown, pay-as-you-go and usage overage. In an interview with Pulse 2, CEO Mark Walker said Nue manages the revenue lifecycle from quote to billing to renewals inside Salesforce. He also said Nue recently added an MCP-based architecture so AI agents can run guarded transactions on Nue and Salesforce data. For teams planning agent-driven quoting, that’s a useful signal about where the product is heading.

Usage data reaches Nue through API connections to your product. That design also supports in-app purchases and user-led expansions, which matters for companies with a product-led motion alongside direct sales. Nue positions itself as an alternative to legacy Salesforce CPQ, so it’s worth a look if you’re planning a CPQ migration anyway. The main limit is scope: Nue only makes sense if Salesforce is your CRM.

2. Certinia Subscription and Usage Billing

Certinia, formerly FinancialForce, is a Salesforce-native ERP, and its billing product connects directly to its accounting and revenue recognition tools. That makes it a strong option when finance wants billing and the general ledger on the same platform as the CRM. Certinia’s usage billing page says it handles products, subscriptions and usage-based billing with pricing and contract terms set in one place. Its product datasheet lists subscription lifecycle management, including amendments and renewals, along with usage pricing and rating.

One analyst profile from MGI Research describes Certinia as best suited to service-centric companies with roughly $25 million to more than $1 billion in revenue. It points especially to companies already using Certinia’s professional services tools. It also notes that Billing Central can run standalone next to a third-party ERP. For a pure software company without a services arm, the full Certinia suite may be more than you need, so scope the billing module on its own. It remains one of the few Salesforce subscription billing options where billing, revenue recognition and accounting run on the same platform.

3. Conga Billing Management and Subscription

Conga, which absorbed the former Apttus revenue products, sells billing as part of a wider revenue lifecycle suite. According to its AppExchange listing, it generates invoices from the latest orders and contracts, covering subscriptions, professional services, hard goods and usage-based services. It also gives a single view of actual and projected invoices, which helps finance forecast cash.

Conga fits larger companies that already use its CLM or document tools and want contracts to drive billing directly. The link between signed contract terms and invoice lines reduces rekeying at renewal time. Teams with simple monthly usage and no contract complexity may find it heavier than they need.

Native apps built for European billing rules

These 2 apps also run natively in Salesforce, but they stand out for e-invoicing and European payment methods. They suit SaaS companies with a large customer base in Europe.

4. JustOn Billing and Invoice Management

JustOn turns contracts, subscriptions or usage data into invoices without leaving Salesforce. Its listing in the AppExchange finance category says it sends compliant e-invoices worldwide and speeds up payment through payment matching and dunning. The same listing shows 77 ratings and a latest release dated June 24, 2026, and it supports Professional Edition and above.

Of the AppExchange billing apps on this list, JustOn’s strength is the step after rating: getting a compliant invoice to the customer and matching the payment that comes back. That’s useful as e-invoicing mandates spread across Europe. It’s a billing tool first, so pair it with a clear quoting process if your renewals involve complex pricing changes.

5. Frisbii

Frisbii, formerly Sofacto, describes itself as a Salesforce-native subscription management, recurring billing and payment app. Its AppExchange listing says it automates invoicing, renewals, dunning and cash collection, and supports flat-rate, tiered, usage-based and per-seat pricing configured inside Salesforce. Pricing starts at €99 per user per month, and the listing showed a 4.91 rating from 33 reviews with an update in June 2026.

Frisbii offers more than 50 payment methods across Europe, including SEPA direct debit, and generates Factur-X e-invoices. Its listing points to the French e-invoicing mandate starting in September 2026, so it’s worth a close look for SaaS companies billing French customers. It’s a lighter fit for US-focused companies with very high usage volumes.

Connected billing engines that sync with Salesforce

These 3 apps run billing on their own platforms and push data into Salesforce. They suit companies with high usage volumes or self-serve channels. They also fit businesses that run more than one CRM, since the billing platform stays the system of record for Salesforce subscription billing data.

6. Zuora

Zuora is the long-standing enterprise choice for subscription and usage billing, and its Salesforce integration comes in layers. The Zuora 360 package sends account, subscription, invoice and product catalog data from Zuora into Salesforce, giving sales and service teams a view of billing and payment history. Zuora now recommends its Connector for Salesforce CRM for more advanced features. The package isn’t a self-serve install, because customers request the installation link from Zuora Global Support.

Zuora also offers a connector that turns Salesforce CPQ quotes and contracts into new, amended or cancelled Zuora subscriptions. Its documentation lists limits worth checking: the CPQ connector doesn’t support Lightning, and custom fields on the Subscription object can’t be sent to Zuora for amendments or renewals. Zuora fits large, multi-product companies that want a dedicated billing platform behind their Salesforce subscription billing process. Smaller teams often find the setup heavy.

7. Chargebee

Chargebee is popular with growing SaaS companies, and its Salesforce package now covers more of the renewal process. According to its Salesforce release notes, the package can close renewal opportunities automatically when contract terms renew or subscriptions cancel. It can also create subscriptions with metered items, and a later release stopped integration-created renewals from overwriting manual changes each night. For SaaS renewal management, that automation cuts much of the cleanup reps used to do by hand.

There are 2 practical points to check. Chargebee’s documentation says the Salesforce integration is available only on selected plans, and the Salesforce package doesn’t update automatically, so you have to contact support for new versions. Chargebee fits subscription-heavy businesses with some usage on top. Companies whose revenue is mostly high-volume consumption may want a deeper metering setup.

8. Maxio

Maxio, formed from SaaSOptics and Chargify, has added Salesforce renewal controls over the past year. Its July 2026 product update made renewal length, auto-renewal timing and uplift percentage visible and editable from Salesforce. The same update put invoice status, payment status and subscription details on Salesforce account and contact records, and added formula-based pricing that combines several usage signals into one price.

Earlier 2026 releases added end-date overrides so new sales orders can co-term with existing contracts, bulk management of auto-renewals and monthly revenue accruals for metered usage on annual contracts. Maxio is a strong pick for finance-led teams that want billing, revenue recognition and SaaS metrics in one place. Reps still see Salesforce usage billing data without the org running billing itself. Critics argue the platform is still subscription-first, so test complex commitment and drawdown contracts carefully.

A renewal forecasting app for customer success teams

The 9th app solves the renewal side of the problem rather than invoicing. Billing apps create renewal records, but someone still has to judge which renewals are at risk and forecast the number. That part of SaaS renewal management usually belongs to customer success.

9. Gainsight Renewal Center

Gainsight Renewal Center helps renewal teams analyze and forecast their book of business. Gainsight’s Renewal Center documentation says it imports data from the Salesforce Opportunity object and enriches those opportunities with customer success insights. Teams use that view to manage renewals and upsells and to spot risk early. It’s sold as an add-on to the Gainsight Customer Success platform, and it appears as Renewals in the user menu.

Usage data matters here as well. Health scores built on product usage are often the earliest warning that a usage-billed customer is shrinking. Gainsight has also moved into services. In June 2026, IT Brief reported that Gainsight launched an AI-native service in which its own teams run renewals for enterprise clients, from outreach through contract negotiation. That option suits companies that want to outsource renewal work, though most teams will start with the software alone.

Side-by-side comparison of the 9 apps

The table below sums up how each app runs and where it fits. Use it to cut a long list down to 3 apps worth a demo.

Among these AppExchange billing apps and connected engines, no single row wins on every column. Native apps give tighter data and simpler reporting, while connected engines handle volume and non-Salesforce channels better. Gainsight can sit on top of either group.

How to choose the right app for your team

The fastest way to narrow the list is to start from your contracts rather than from feature lists. Pull 5 real contracts that represent your hardest cases and use them as the test for every demo.

1. Map your pricing models. List every way you charge today and plan to charge within 2 years, including seats, usage tiers, prepaid credits, minimum commitments and overages. Drop any app that can’t model all of them without custom code. If usage-based pricing is on your roadmap but not live yet, include it in the test anyway.
2. Trace your usage data. Find out where usage events start, how many arrive per day and how fast they need to show up on an invoice. High volumes push you toward apps that process events outside the org.
3. Decide where the system of record lives. If Salesforce is the only place customers buy, a native package keeps things simple. If you also sell through self-serve checkout or another CRM, a connected engine may fit better.
4. Test a renewal end to end. Ask each vendor to renew one of your contracts with a price uplift, a usage-based commitment change and a co-termed add-on. Watch how the renewal opportunity, the quote and the next invoice line up.
5. Check the finance handoff. Confirm how invoices, credits and revenue schedules reach your ERP, and who fixes a failed sync.
6. Compare against Agentforce Revenue Management. Get a quote and roadmap from Salesforce too, since its planned metering capabilities may change the cost case for a third-party app.

Budget for people as well as licenses. A native app needs a Salesforce admin who understands billing objects, while a connected engine needs someone who can manage 2 systems and the sync between them. Ask vendors which roles their successful customers staff, and compare that with the team you actually have.

Keep scoring simple. A shortlist of 2 or 3 apps tested against real contracts will tell you more than a 50-row feature matrix. Billing platforms are hard to replace once invoices and renewals run through them, so time spent on testing is worth it. The same discipline applies to SaaS renewal management tools, since renewal forecasts feed board-level revenue numbers.

Common mistakes when adding usage billing to Salesforce

Most failed rollouts of Salesforce usage billing trace back to data and process rather than the app itself. The first common mistake is treating usage data as an afterthought. Teams sign a contract, then discover their product logs don’t carry the account IDs the billing app needs. Fix the usage pipeline before go-live, and agree on what counts as a billable event.

The second mistake is copying old price books into a new tool. Legacy SKUs built for seat pricing often multiply when usage tiers are added. Use the migration to cut SKUs, because every extra product adds work at every renewal.

The third mistake is leaving renewals out of scope. Many projects focus on the first invoice and forget the renewal. Then renewal opportunities show the wrong amount, or a renewed contract fails to update the billing schedule. Include renewals, amendments and co-terming in user acceptance testing.

The fourth mistake is unclear field ownership in connected setups. When 2 systems can both edit the same field, the numbers drift. Write down which system owns each field before you build the integration, and set alerts for sync failures.

The last mistake is ignoring the people who use the data. Sales reps and customer success managers need to see usage and invoice status on the account page. If that view is missing, they’ll keep asking finance, and the main benefit of putting billing near the CRM disappears.

Where this leaves Salesforce teams

Salesforce usage billing is now a choice between 3 paths: Salesforce’s own Agentforce Revenue Management, a native AppExchange app or a connected billing engine. Salesforce’s purchase of m3ter could strengthen the native Salesforce option as the planned capabilities are added, but it doesn’t remove the need for third-party apps. Many companies need European e-invoicing or a self-serve channel. Others want deep finance tools or a lighter setup than an enterprise suite. AppExchange billing apps and connected engines still fill those needs.

The 9 apps here cover those needs from different angles. Nue, Certinia and Conga keep quoting and billing in the org. JustOn and Frisbii add strong European billing rules. Zuora, Chargebee and Maxio run billing outside Salesforce and sync it back, while Gainsight helps teams forecast and protect renewals. The right choice for Salesforce usage billing comes from testing real contracts, especially the messy ones with price ramps and mid-term changes. Teams that also invest in SaaS renewal management, with usage visible before each renewal opens, get the most value from whichever billing app they pick.

Frequently asked questions

What is Salesforce usage billing?

Salesforce usage billing is the process of turning product usage into invoice charges tied to contracts managed in Salesforce. It covers collecting usage records, pricing them against the contract and producing invoice lines that every customer-facing team can see.

Does Salesforce have built-in usage billing?

Yes. Revenue Cloud Billing, now part of Agentforce Revenue Management, covers usage rating, invoicing, payments and collections. Salesforce acquired m3ter on July 1, 2026, to add high-volume mediation, metering and rating capabilities to Agentforce Revenue Management.

Is Salesforce CPQ still available?

Salesforce CPQ moved to end-of-sale status in March 2025. Existing customers can keep using it, but new customers can’t buy it. Salesforce points new buyers to Revenue Cloud Advanced instead.

What’s the difference between a native app and a connected billing engine?

A native app installs into your Salesforce org and stores billing records there. A connected engine runs billing on its own platform and syncs data back to Salesforce. Native apps simplify reporting, while connected engines usually handle higher volumes and other sales channels.

Which AppExchange billing apps are native to Salesforce?

On this list, Nue, Certinia, Conga, JustOn and Frisbii run natively inside Salesforce. Zuora, Chargebee and Maxio are connected billing engines, and Gainsight works from synced Salesforce opportunity data.

Which app is best for hybrid subscription and usage pricing?

Nue is built for usage-based pricing combined with subscriptions on Salesforce, with credit burndown, pay-as-you-go and overage options. Maxio and Chargebee also support hybrid models from outside Salesforce. Test each with a real contract before deciding.

Which apps help most with European e-invoicing?

JustOn and Frisbii focus on compliant e-invoicing. Frisbii generates Factur-X invoices and points to France’s mandate starting in September 2026, while JustOn sends compliant e-invoices and matches incoming payments.

Can these apps create renewal opportunities automatically?

Several can. Chargebee’s package closes renewal opportunities when terms renew or subscriptions cancel, and Maxio lets teams edit renewal length, timing and uplift from Salesforce. Native apps like Nue manage renewals as part of the same quote and subscription record.

How does Gainsight fit with a billing app?

Gainsight Renewal Center doesn’t send invoices. It pulls Salesforce opportunity data and adds customer success insights so teams can forecast renewals and spot risk. Most companies run it alongside a billing app.

How much do these apps cost?

Most vendors of Salesforce subscription billing tools quote prices privately based on users, revenue or volume. Frisbii lists a starting price of €99 per user per month on its marketplace listing. Ask every vendor for implementation costs as well as license fees.

Is the Zuora Salesforce package on a self-serve install?

No. Zuora customers request the Zuora 360 installation link from Zuora Global Support. Zuora also recommends its newer Connector for Salesforce CRM for more advanced features.

Do I need to move off Salesforce CPQ right away?

Not necessarily, since Salesforce still supports existing CPQ customers. Many teams use the end-of-sale notice as a reason to review their Salesforce usage billing setup, especially if they’re adding usage-based pricing.

How long does it take to implement a billing app?

It depends on contract complexity, data quality and integrations. Simple subscription setups can go live faster than Salesforce usage billing projects with high-volume usage feeds and ERP links. Ask vendors for timelines from customers with similar contracts.

What should I test in a billing app demo?

Bring real contracts. Ask the vendor to quote, bill and renew one with a price ramp, an overage and a mid-term upgrade. Check how the renewal opportunity and the next invoice line up in Salesforce.

Should SaaS renewal management live in the billing app or a separate tool?

Billing apps handle renewal terms and invoices well, and good Salesforce subscription billing tools create renewal opportunities on time. Forecasting renewal risk often needs customer health and usage signals, which is where a tool like Gainsight helps. Larger teams usually run both.
