> Add one or more payment methods to an invoice, and invoice in another currency with an exchange rate to AED.

An invoice tells the buyer how to pay and in which currency. Alya Books prints the payment methods on the PDF and includes them in the e-invoice. For another currency than AED, the invoice also states VAT and the total in AED.

## Payment methods

1. In the invoice editor, find **Payment methods** next to the payment terms.
2. Choose the **Payment method**, for example credit transfer, card, direct debit, cheque or cash. The fields change with the method:
- Credit transfer: your account from **Settings → Bank details** is used when it has an IBAN. Click **Use another account** to enter a different **IBAN / account number**, **Account holder**, **BIC / SWIFT** and **Bank name**.
- Card: **Card number (last 4 to 6 digits)**. Never enter the full card number.
- Direct debit: **Mandate reference** and **Debited account (IBAN)**.
3. Add a **Payment reference** (for a cheque: **Cheque number / reference**) and **Payment text** if the buyer needs them. **More** shows extra fields such as **Instruction ID**.
4. Click **Add another payment method** to offer more than one (up to 10).

IBANs are checked as you type. See [Add bank details](/help/en/account-and-setup/bank-details).

## Invoice in another currency

Choose the **Currency** in the meta block, for example USD. The field **Exchange rate (AED per 1 USD)** appears next to it, filled in with the UAE Central Bank rate for the date of supply. The totals box, the PDF and the e-invoice then also show VAT and the total in AED. See [Invoice in another currency](/help/en/invoices/other-currencies).

## Good to know

- An invoice allows at most one card payment and one direct debit.
- The currencies and payment methods you can pick come from **Settings → Codes & regions**. Nine everyday payment methods are on by default; every other official code (91 in all) is valid on UAE e-invoices and can be switched on there.
- Codes Z01 to Z08 are official but not yet on Taxilla's list, so an invoice that uses one is stopped at validation. Alya Books support lifts this once Taxilla accepts them.
