BILLING & INVOICING

Generate Accurate Invoices from Usage Data

Turn usage into invoices automatically. Preview charges before sending, export to accounting systems, and track AI costs and margins down to the customer level.

Generate usage-based invoices automatically

  • Convert metered events into accurate invoice line items
  • Combine usage charges with subscriptions and one-time fees
  • Apply credits, discounts, and proration without manual calculation

Issue one-off invoices for custom charges

  • Bill for setup fees or custom agreements
  • Send invoices outside regular billing cycles
  • Track payment status for ad-hoc charges

Preview invoices before they finalize

  • Show customers what they'll be charged before payment runs
  • Catch billing errors before they become disputes
  • Let customers adjust usage or top up credits to control costs

Track AI costs and margins per customer

  • See compute costs, model usage, and revenue per customer
  • Calculate margins at account, feature, or product level
  • Identify which customers are profitable vs burning budget

Flexprice lets us focus on the core business instead of building billing as a second product.
