Every transaction, verified before funds move.
Rein is the control plane for lenders and factors in agentic commerce. It verifies each invoice and each drawdown at transaction level, with business and market context, against the lender's own rules.
What Rein does
Transaction-level controls, with real context.
What is being bought, whether the price is sane against the market, whether the merchant is real, and whether it fits the borrower's business - checked as transactions happen, not in a monthly review.
Verify every advance
Each invoice and drawdown is checked individually, with business and market context behind every decision.
Your rules, applied
The lender sets the policy: limits, advance rates, escalation rules. Rein applies them deterministically - no model deciding credit on its own.
Live, not monthly
Checks run as transactions happen. Facility freshness becomes a live control, not a monthly PDF.
API and webhooks
Every decision - approve, hold or escalate - is delivered through API and webhooks, so it fits existing credit operations and tools.
The control plane
How it works
The lender keeps the credit decision, the funds and the books. Rein is the verification step in between.
The lender sets the policy
Limits, advance rates, approved payees and categories, escalation rules. The lender decides where a human signs off.
Rein verifies each transaction
Every invoice and drawdown is checked against the policy, with business and market context: what is being bought, is the price sane, is the merchant real, does it fit the business.
Decisions land where you work
Approve, hold or escalate - delivered through API and webhooks into existing credit operations, and works alongside operator-side evidence providers.
Built for lenders and factors
Catch bad advances before funds move.
