Recurring revenue management software for B2B SaaS
A B2B SaaS company bills the same customers every month, so small billing gaps repeat every month too. RevenueLeak connects read-only to Stripe, Paddle, Chargebee or Recurly, audits your invoices and subscriptions against nine leak categories, and shows founders and finance one number in dollars per month with the accounts behind it. The payment part is then recovered with retries by decline code and recovery emails you switch on yourself.
Why SaaS billing leaks without anyone noticing
SaaS revenue looks stable on a chart while it erodes underneath. A renewal fails and the subscription ends after two retries. A sales rep gives a three month discount that was created as forever. An account adds five seats in the middle of the period and the difference is never invoiced. A design partner from the first year still pays the launch price. None of this shows up as an error, and none of it appears as a line item in the books. Finance sees only that net revenue retention is lower than the plan.
- Involuntary churn from failed renewals that were not retried in full.
- Legacy prices on accounts that signed up before the last price change.
- Seat and plan changes without the prorated invoice.
- Comped accounts and open-ended coupons on large customers.
What the audit reads in your billing system
RevenueLeak reads invoices, subscriptions, customers, prices, coupons, refunds and disputes through the official API with a restricted, read-only key. It never creates charges, edits subscriptions or changes prices. Every finding carries the source invoice, the rule that flagged it and the dollar amount per month. The result is a ranked list of accounts to fix, sorted by money, so the first hour of work goes to the biggest gap. The full structure of the report is on the billing leakage page.
| Leak category | What the audit checks | Typical fix in SaaS |
|---|---|---|
| Failed renewals | Attempts per invoice and decline codes | Retry schedule by decline code and recovery emails |
| Expiring cards | Expiry date against the next renewal | Pre-expiry card update email |
| Legacy prices | Active price against the current list price | Ranked list for a price migration |
| Unbilled upgrades | Seat and plan changes against invoices | Corrected proration setting |
| Comped accounts | Full discounts with active billing | Review list with the full price |
| Forever coupons | Coupon duration and the accounts it covers | End dates on open-ended discounts |
Failed renewals in B2B are usually recoverable
A B2B card fails for ordinary reasons: a company card reached its monthly limit, a corporate card was reissued, the issuer flagged an unusual amount on an annual renewal. The customer still wants the product. RevenueLeak reads the decline code of each attempt and handles soft and hard declines differently. Soft declines are retried at different hours over several days. Hard declines are not retried, and the billing contact gets an email with a secure payment update link instead. The details of the schedule are on the failed payment recovery page, and cards that are about to expire are caught earlier by the card updater.
- Retries stop at once when the card is updated or the invoice is paid.
- Recovery emails go from your verified domain, under your brand.
- If built-in retries are on, we keep them and add only what is missing. See stripe smart retries.
One number a founder can act on
Founders do not need another chart of MRR. They need to know how much money is slipping away this month and which accounts to fix first. The audit gives a monthly leak in dollars, split by category, with a short action per account. Pricing and discount fixes stay in your own billing system, done by your team, so nothing changes without a person deciding it. Recovery runs on its own once you switch the rules on, and each recovered dollar is reported against the invoice it belongs to.
What finance gets from the same data
The same audit is a finance document. It states the period, the method, each category and the accounts behind every amount, and it exports to CSV on every plan and to PDF from Growth. Finance teams attach it to the monthly close or a board update. The trends behind it, such as recovered revenue and the leak rate by month, sit in subscription analytics. Teams that report to a CFO or investors read more on the customer retention platform page.
Do the arithmetic on your own numbers
Take your MRR and the share of renewals that fail each month. Subtract what your current retries bring back, then add legacy price gaps and open-ended discounts from your own price list. For example, a company with 50,000 USD MRR where 1,000 USD per month of renewals is lost after a failed payment, and half of that is brought back, recovers 500 USD per month, or 6,000 USD per year. Growth costs 1,788 USD billed yearly. Compare the result with the plans on the revenue optimization software page.
Set up in about ten minutes, no engineering time
You create a restricted key with read permissions or authorize the app on your billing platform, then pick which rules to switch on. There is no SDK to install and no code to deploy. Usage-based invoices are audited like any other invoice, and multiple currencies are reported in each currency with a USD total. Teams on more than one billing account connect several accounts from Growth up.
Questions from SaaS teams
No. Your billing system keeps billing. RevenueLeak reads it, prices the leaks and runs recovery rules you switch on.
No. The connection is read-only. Price migrations and discount fixes are done by your team in your own billing system.
Yes. Usage invoices and seat changes are checked against the invoices that should follow them, including prorated differences.
The plan follows your MRR band. Starter covers MRR up to 10,000 USD, Growth up to 100,000 USD and Scale up to 1,000,000 USD.
Yes. The estimate on the home page runs without an account and needs no card. The audit and recovery are part of the paid plans.
