Quick Answer

Pro forma billing refers to issuing a preliminary bill based on projected or estimated charges — commonly used for subscriptions, service contracts, or upcoming shipments — so the buyer sees a clear cost preview before the final, legally binding invoice is generated.

Common Challenges Businesses Face

Without the right tool, creating and tracking pro forma bills becomes a manual, error-prone process.

No Preview Before Recurring Charges

Subscription and service businesses often bill customers directly without warning, leading to payment disputes and support tickets.

Estimates Don't Match Final Bills

When pro forma amounts are calculated manually, they frequently drift from the final invoice total, damaging customer trust.

No Automation for Repeat Billing Cycles

Recalculating and resending pro forma bills every cycle by hand doesn't scale as the customer base grows.
