Automated secure vendor receipt aggregation via permissioned connectors

Small and mid-sized businesses and their accountants lose hours each month to hunting receipts, logging expenses manually, and reconciling vendor portals that don’t export usable transaction data. With 200 million SMBs globally and an estimated $48.0B addressable market (about $240 per SMB per year), this is a persistent operational cost that scales across industries and geographies. A practical product would combine a library of permissioned connectors (OAuth/API-first) to vendors and payment platforms with a Document‑AI layer that extracts, classifies, and validates receipt data into standardized, ledger-ready records. Core features should include consent management, immutable audit trails, automated reconciliation hooks into Xero/QuickBooks/etc., and an accountant-facing exceptions workflow to minimize manual review. Timing favors this approach: Document‑AI accuracy has materially improved in the past 24 months, many vendors are moving toward permissioned APIs rather than credential scraping, and cloud accounting penetration among SMBs continues to rise. Those trends, together with a Market Score of 78/100 and Revenue Potential of 88/100, support viable recurring revenue if you secure distribution through accounting firms and platform partners. To stand out you must prioritize vendor-first permissioned connectors with demonstrable parsing accuracy (target >95% parsed-field accuracy), enterprise-grade consent and auditing, and deep integrations so the service becomes a source of truth rather than another silo. Real challenges include the upfront engineering and maintenance cost of many connectors, uneven vendor cooperation and regional compliance requirements, and customer acquisition costs, so early success will depend on a focused set of high-volume vendor partnerships and CPA channel validation before scaling.
