Company profile

researched Aug 2026

OatFi operates a credit network delivered through APIs that B2B payments platforms embed into their existing flow of funds. The platform lets partner platforms extend liquidity to their buyers and suppliers, enabling early payment to suppliers, extended billing cycles or net terms for buyers, and automated reconciliation of payments to invoices, without the platform itself raising capital or contracting multiple vendors.

The product is organized as modular building blocks covering KYB verification and fraud prevention, underwriting and automated credit decisioning, origination and distribution of funds, a proprietary loan management system and ledger for real-time account status and reconciliation, capital markets access through OatFi's funding partners with associated reporting, and servicing and collections. A typical transaction flow has the partner platform pass buyer and supplier underwriting data and invoice data to OatFi, which returns an instant credit decision, funds the supplier's early payment or guarantees on-time payment, collects from the buyer on terms or via scheduled billing cycles, and reconciles the payment against the invoice.

Business model

OatFi supplies the infrastructure and the capital layer to partner platforms, positioning accounts payable and accounts receivable workflows as a revenue source for those platforms and providing access to its funding partners so platforms do not have to raise their own capital.

Traction

The company publishes case studies covering commercial charge cards with Unit, accounts receivable funding with Avalara, instant payments to legal talent with Lawtrades, advanced payments on healthcare claims, and net terms for a procure-to-pay platform and a spend management platform.

Market position

Positions itself as a modern credit network for B2B payments, providing an embedded trust and liquidity layer for platforms handling accounts payable and accounts receivable.

Combines credit infrastructure with access to capital in one integration, so platforms can launch net terms and early payment programs without vendor spend or balance-sheet funding, with modular components that can be assembled to fit each platform's feature set.

Technology

A single set of APIs spanning underwriting, instant credit decisioning, funding, payments and reconciliation, supported by a proprietary loan management system and ledger, KYB and fraud tooling, and automated capital markets and servicing workflows.

Go-to-market

OatFi sells through embedded partnerships with B2B payments platforms, which integrate its APIs and offer credit to their own end users; published case studies describe deployments with platforms such as Avalara, Unit and Lawtrades, plus a procure-to-pay platform, a spend management platform and healthcare providers receiving advanced payments on claims.

B2B payments platforms, including bill pay and invoicing providers, spend management and procure-to-pay platforms, B2B marketplaces, and platforms serving a contingent workforce that need early payouts for workers after work is completed.
