USD, excluding tax. Human verification required.

Variances must be manually investigated before any payment decision. Taxes, discounts, partial invoices and multiple receipts require additional rules in the production product.

Our product hypothesis
A review queue for small teams, not another accounting suite.
We're exploring a lightweight workflow for businesses that have purchase orders and deliveries but don't want to replace their entire accounting system.
- Find line-level changes with source references
- Track partial deliveries and approvals
- Export an audit trail for the person making the decision

Pilot research
Do invoice mismatches cost your team time?
We're looking for small teams that compare incoming invoices against orders and deliveries. Help shape a tool that focuses on exceptions, not busywork.
