Failed payments are leaking revenue
Failed transactions are a measurable revenue leak for SaaS platforms — roughly 9% of revenue is estimated lost to failed payments, about $12B globally, according to recent commentary. At the same time, new benchmarking tools for B2B SaaS (covering CAC, CPC and local markets) are circulating to help teams quantify where payment failures and acquisition economics bite margins.

A software company can spend $2 to win $1 of new annual recurring revenue, then lose part of that customer a month later because the card on file expired or the bank said no. Benchmarkit’s 2025 data put median new customer acquisition cost ratio at $2.00, up 14% in 2024, which makes every avoidable failed charge more expensive than it looks. (benchmarkit.ai) That leak is not always a customer quitting. In subscription billing, a failed payment can push an account into “past due,” “incomplete,” or cancellation even when the customer still wants the product and never opened a pricing page. (docs.stripe.com) (developer.paddle.com) Payment processors treat this as a retry problem because many failures are temporary. Stripe says failed-payment retries are one of the most effective ways to recover revenue, and its default recommendation is 8 retry attempts within 2 weeks. (docs.stripe.com 1) (docs.stripe.com 2) The reason retries work is simple: banks decline for lots of reasons that have nothing to do with product demand. Adyen’s refusal codes include insufficient funds, expired cards, transaction-not-permitted rules, and issuer declines, which means the same customer can succeed later without any sales call. (docs.adyen.com) The industry has been putting bigger numbers on the table as billing teams try to show this is not rounding error. Recurly said involuntary churn could leave more than $129 billion on the table across subscription companies in 2025, and its 2025 report said subscriber acquisition rates fell to 2.8% from 4.1% in 2021, which makes retention work more valuable than it was a few years ago. (recurly.com) (businesswire.com) That is why new business-to-business software benchmarks are getting shared so aggressively right now. Baker Tilly and Benchmarkit say their 2025 dataset covers more than 500 software-as-a-service companies and lets teams filter customer acquisition cost, payback period, pricing model, customer segment, and region instead of comparing a United States enterprise seller to a self-serve startup in another market. (bakertilly.com) (maxio.com) Once you look at the numbers together, failed payments stop looking like a billing-side nuisance and start looking like wasted acquisition spend. If sales and marketing already consume 47% of revenue at venture-backed software firms in the Benchmarkit sample, every recovered renewal is cheaper than replacing that customer from scratch. (benchmarkit.ai) The operational fix is usually boring on purpose. Billing systems now push automated emails, in-app prompts, card-updater flows, and timed retries so finance teams are not manually chasing every declined invoice one by one. (paddle.com) (docs.stripe.com) The shift underneath all of this is that software companies are measuring margin leaks with the same seriousness they used to reserve for growth charts. In a market where net revenue retention was 101% and expansion revenue made up 40% of total new annual recurring revenue in Benchmarkit’s 2025 data, a failed renewal is no longer just a missed payment; it is a hole in the model.
