Custom Order Deposit & Balance Payment App

92% Confidence Medium Market Medium Difficulty $3k-10k MRR Updated Jun 23, 2026

The Opportunity

An app that lets merchants collect a partial deposit for custom or made-to-order jobs, then automatically issue a second invoice or payment link for the remaining balance when the order is ready. It is designed for merchants who use drafts, custom invoices, or bespoke order workflows rather than standard product checkout.

"Merchants selling custom work need an easy way to take upfront deposits without requiring full payment at checkout, then collect the remainder later."
