Currencies and exchange rates

Bill a client in their currency and read your books in yours. Finocket supports 16 currencies, converts every total back to your home currency, and locks the rate onto each document so an old invoice never silently changes value.

Your home currency

Your home currency is the one your reports are written in: Trial Balance, Profit & Loss, Balance Sheet, dashboard totals. Every foreign-currency document is converted into it at the rate in force on that document's date.

Rates are snapshotted, not looked up

Every invoice takes a copy of the exchange rate at issue-date time and keeps it. Change a rate today and historic invoices stay at their historic rate, which keeps last quarter's figures reproducible.

  • Add a new rate for a currency pair, or update an existing one in place.
  • Your dashboard warns you when an invoice or payment is missing a rate, rather than converting it at 1:1 or leaving it out silently.

What happens to a total when a rate is missing

A payment in a currency with no rate on file is left out of the home-currency total and counted. The screen says how many and which currencies (for example, “5 payments not included — no exchange rate for AUD or USD”), and the row itself still shows its own amount with its own symbol.

It is not added at face value. Two thousand dollars is not two thousand rupees, and a total that mixes them is not a quantity of anything. A figure that is short by a stated number of rows can be acted on; one that is wrong by an unknown amount cannot. Add the rate and the row joins the total.

This applies everywhere a home-currency total appears: the Cashbook, the Day Book, your dashboard, the cashflow chart, outstanding and ageing, and the reports and exports you hand to an accountant.

What Finocket will not do

  • It will not fetch live rates for you. The rates are the ones you enter, so every figure in your books is one you can point to a source for.
  • It will not re-rate a document you have already issued. Editing a rate affects documents issued from then on.
  • It will not fold foreign-currency amounts into a tax working. Money held in a currency other than your workspace's is left out of the tax plan, with a count and an explanation, rather than being counted as rupees.

Frequently asked questions

How many currencies does Finocket support?

Sixteen. Every foreign-currency document is converted back to your home currency for your reports.

If I change an exchange rate, do my old invoices change?

No. Every invoice snapshots the rate at issue-date time and keeps it, so historic figures stay reproducible. A rate change applies to documents issued from then on.

Does Finocket fetch live exchange rates?

No. The rates are the ones you enter, deliberately: a figure in your books should be one you can point at a source for, not one that moved while you were not looking.

What happens if a rate is missing?

Your dashboard warns you that an invoice or payment has no rate, rather than converting it at 1:1 or leaving it out silently.

What is the difference between this and foreign-currency revaluation?

This screen sets the rates documents are issued at. Revaluation restates your still-open foreign-currency balances at a period-end rate, a separate job with its own guide.
