Why this matters
Billing lag isn't a back-office nuisance. It's a silent tax on your growth.
Billing lag is the gap between earning revenue and receiving cash. It includes days before invoicing, time lost to corrections, and waiting for payment. This gap ties up capital, distorts forecasts, and slows growth for B2B companies.
- Typical B2B SaaS DSO
- 30–90 days
- Cash trapped at $5M ARR
- ~$620K
- Of invoices contain an error
- 39%
Calculate your number
Estimate only: uses illustrative assumptions (avg. 6-day delay per corrected invoice, 10% assumed cost of capital) to turn your inputs into a directional dollar figure.
Three gaps, one number: your total billing lag.
Contract → Invoice
Time from signature to a sent invoice. Batching invoices weekly or monthly can silently add 10–15 days here alone.
Manual Correction
Errors and rework before an invoice is correct enough to send: more common, and more costly, than most teams realize.
Invoice → Cash (DSO)
Time from invoice sent to payment collected. Older invoices are less likely to be fully paid.
