Revenue Recognition
Lago turns invoices, usage and credit notes into the revenue you earned, period by period.
The service period drives recognition, not the invoice or payment date. Daily for time-based service, at consumption for usage.
Tax is booked as a liability you owe the authority. It never counts as revenue.
Credit notes, disputes and true-ups land in the period they occur. Earlier periods are never rewritten.
Each billing event becomes a balanced double-entry record. Recognized plus deferred revenue always ties back to what you invoiced.

Lago applies the recognition logic to your billing data.
$50.00 monthly fee, billed in advance on Jan 1
A $50.00 monthly fee invoiced in advance on January 1 starts in deferred revenue. Lago recognizes about $1.61 each day of January, so deferred revenue drains to zero by January 31, with the final day absorbing the rounding.
Recognized day by day.Each fee is split evenly across the days of its service period. Monthly and annual figures are the days added up.
Billing is mission-critical. Lago is engineered for the realities of high-volume enterprises.

Revenue recognition turns the billing data already in Lago (invoices, subscriptions, usage, payments, credit notes and wallets) into accrual-basis revenue for every period. Invoicing tells you what you billed. Revenue recognition tells you what you earned, which is rarely the same number in the same month.
