Proofstitch, a Paper Trail for Deposit Deductions

Field notes

Proofstitch structures deposit accounting around individual deductions rather than treating the final letter as a standalone form. Its prompts ask users to distinguish damage from ordinary wear and tear, while the packet keeps each charge alongside its supporting records. The homepage names inspection notes, invoices, receipts, and before-and-after photos as inputs, and shows a sample calculation turning a $2,400 deposit and $280 repair charge into a $2,120 refund. State timing is surfaced through examples such as California's 21-day rule.
