Automated, secure monthly receipt collection for SMBs & accountants (no 2FA hacks)

Small businesses and the outsourced accounting firms that serve them face a repetitive, low-margin problem: collecting and reconciling monthly receipts. Across the targeted geographies there are roughly 10 million SMBs, representing a $6.0B addressable market at an average $600 ACV, and many firms still rely on manual uploads, emailed PDFs, or insecure credential-sharing that wastes staff time and invites 2FA workarounds and security exposure. The product to build is an automated, secure monthly receipt-collection service that combines vendor-supplied receipt/transaction APIs and OAuth/open-banking connectors (avoiding credential scraping and 2FA hacks) with AI OCR/NER for line-item extraction and prebuilt integrations into QuickBooks, Xero and common bookkeeping platforms. It should include a human-in-the-loop exception workflow and audit trails so bookkeepers can scale without compromising accuracy or security. Timing is favorable: OCR and NER models have materially reduced human review needs, more vendors now expose receipts/transaction APIs, and outsourced bookkeeping is growing—creating channel partners that will pay for automation. The $6.0B market and $600 ACV mean even modest penetration (1–5%) produces meaningful revenue upside and customer LTV for focused go-to-market efforts. This idea can stand out by prioritizing security (no stored credentials, permissioned read-only integrations, full audit logs), by targeting a >90% extraction accuracy goal with quick human fallback, and by selling through accounting firms with co-branded workflows. Be honest about challenges: vendor API fragmentation, the cost of onboarding legacy clients, and a medium-competitive field that will require differentiated integrations and channel partnerships to win.
