Under-billing and missed contract escalators
For B2B services, software and anyone billing from contractsWork delivered and never invoiced, annual price escalations that the billing system quietly renewed at last year's rate, scope that grew without the contract following it. It does not feel like a loss because nothing goes missing. Revenue simply never arrives.
Across industries, companies lose between 2% and 10% of earned revenue to systemic billing errors, and B2B SaaS specifically loses 3% to 5% of ARR. Fewer than 35% of billing systems apply every contracted escalator automatically. Sources: LedgerUp, LeaksShield 2026 statistics
Assuming $20M of revenue billed from contracts, leaking at the low end of 3%: $600,000 a year
This is the closest one to work I have actually done. It is reconciliation between a contract, a delivery record and an invoice, which is the same shape as three builds on the catalog that are running today.
