# Treasurer Paying Overseas Suppliers: Stablecoin FX Through an API to Stop Losing Margin on Every Remittance in Brazil

> How a treasury tracks, in the Crown FX API, the costs that build up per remittance to overseas suppliers: spread, FX IOF and timing.

Remittance after remittance, a treasury absorbs spread, IOF and settlement delay. This is what changes when the flow goes through the [Crown FX](https://crown-brlv.com) API.

| Per-remittance cost | Effect through the API |
| :--- | :--- |
| Spread | Exposed in the quote before the order is confirmed |
| FX IOF | Not incident; traditional FX bears up to 3.5% |
| Settlement time | Minutes, instead of up to two business days |

**Tracking it.** Keep each quote next to the bank's, and use the transaction history and the webhooks to reconcile what settled. No savings percentage is published by Crown, so the gain has to be measured on the company's own volume and quotes.

**Boundaries.** Payments carry a documented ceiling of US$ 100,000 per operation, and Crown gives no tax advice.
