CURRENCY & COUNTRY
Make every invoice clear, wherever your customer is
Currency-based billing helps you describe prices for international customers. This published Sleek Bill invoice sample shows the document layout. The Sri Lanka setup guide separately documents selecting LKR.
- Choose the currency. The Sri Lanka guide shows selecting LKR in your business preferences.
- Agree the exchange rate. If you quote in a different currency, confirm which rate and date you and your customer will use.
- Check the final totals. Confirm the invoice currency, tax settings and payment terms before sharing.
Illustrative conversion: USD 100 × 300 LKR/USD = LKR 30,000 before tax. This is an explanation, not a live rate or a promise of automatic conversion.
