If your software platform has business customers who occasionally need cash — to cover payroll, restock inventory, or bridge a slow month — you can either watch them go find financing somewhere else, or offer it yourself without becoming a lender. Kanmon and Parafin both exist to make that possible, list each other as direct alternatives, and both handle the underwriting, funding, and regulatory compliance behind an API. Where they diverge is who they're actually built for.
Kanmon
Kanmon is built for B2B software platforms — practice management, professional services, healthcare, supply-chain tools — that want to offer their business customers loans and lines of credit directly inside the software they already use. Underwriting takes under 10 minutes and funding lands within 24 hours, with Kanmon carrying all the credit risk and compliance burden.
Strengths: genuinely fast integration (about a week, by Kanmon's own account), soft credit checks that don't ding the borrower's score, and Kanmon absorbs the regulatory and credit-risk work entirely.
Watch out for: no published pricing, fees, or interest rates — you'll need a sales conversation to find out what it actually costs. It's also US-only, and it requires you to already be an established software platform rather than working as a standalone product.
Parafin
Parafin is the infrastructure quietly behind the financing offers on platforms like DoorDash and Amazon — white-labeled working capital, payment cards, and installment payments that a merchant or freelancer accesses without ever leaving the host platform. It's built for B2B2C marketplaces and SaaS platforms serving smaller merchants, not for direct B2B lending relationships.
Strengths: proven at serious scale ($35B in financing offered, 50,000+ businesses funded), fully white-labeled and customizable branding, and a choice of no-code, low-code, or full API integration depending on how much control you want.
Watch out for: pricing isn't published as a fixed grid — Parafin shares worked examples (like a $9,000 advance with a $1,080 fee, repaid as 13% of daily sales) rather than a rate card, so the real cost depends on the specific business. It's also built specifically for the B2B2C case — a platform financing its own merchants — not for direct B2B lending.

Verdict
Pick Kanmon if you run a B2B software platform and want to offer your business customers a loan or line of credit fast, with an integration you can ship in about a week and minimal ongoing involvement in the credit decision.
Pick Parafin if your platform serves smaller merchants or freelancers (a marketplace, a vertical SaaS with a merchant base) and you want proven, white-labeled financing at scale, with the flexibility to start no-code and move to a deeper API integration later.
