The customer sees one GBP amount—not the raw supplier-cost calculation.

Example only. Every quote preserves the policy inputs used to create it.

The pivot

Don't resell exchange rates. Sell a stable local price.

Live pass-through conversion makes every invoice unpredictable. RateWeaver creates a price book for each client, records its commercial rules with each model, and keeps the FX input fixed for the UTC calendar month.

01

Capture cost

Normalize any upstream provider charge into exact USD microdollars.
02

Create the local price

Apply a locked FX quote, risk buffer, margin, minimum, and rounding rule.
03

Preview one metering amount

Generate a local-currency event shape; external delivery stays blocked until approval.

Easy for the business

A policy your finance team can explain.

Every model carries the source cost, locked rate, buffer, markup, and proposed customer amount. Real billing still requires commercial activation and downstream reconciliation.
