Set a default currency per AR account so city ledger payments are held in that currency, not the base currency.

Business Value

  • Bill each AR account in the currency you agreed with them.
  • Removes manual conversion when settling foreign-currency city ledger accounts.
  • Locks the exchange rate at posting time for accurate reconciliation.
  • Shows the payment currency before you post, preventing wrong-currency entries.
  • Keeps base-currency reporting intact alongside the foreign amounts.

Use Cases

  • Accountant sets a travel agency’s AR account to USD so its invoices settle in USD.
  • Front desk agent posts a city ledger payment and sees the account’s currency before confirming.
  • Finance controller reconciles a foreign-currency account without recalculating rates by hand.

How It Works

Set a Default Currency on an AR Account

  • A Default Currency field on the AR account lets you pick any currency configured on your system.
  • The field is optional. Leave it empty and the account uses the system base currency.
  • This single setting drives the currency of city ledger payments, AR main postings, and invoices for the account.

How City Ledger Payments Use the Currency

When you post a city ledger payment, the system settles it in the currency of the AR account linked to the billing window:
  1. The payment is made in the AR account’s default currency.
  2. Any posting in the window held in a different currency is converted to that currency.
  3. Each posting is stored with its own currency and the exchange rates in effect at the moment it was posted — conversion uses that saved rate, not today’s rate.
  4. The payment creates an AR Main Posting carrying the city ledger posting’s currency.

See the Currency Before You Post

A read-only Currency field sits under the Department field on the payment screen, alongside Exchange Rate, so you can confirm the currency before posting. What it shows depends on the department:

If the Feature Is Turned Off Later

If the flag is disabled after a default currency was already set on an AR account:
  • The Default Currency field becomes dimmed and read-only again.
  • City ledger payments for that account revert to the system base currency.
Existing postings keep the currency and exchange factor they were saved with.
