Systematic Invoice

Currencies and rates

Invoice in any currency. Your totals stay right because every document keeps the rate of its own date.

The default currency

Choose it in Settings → Language & Format before your first invoice. The dashboard and reports add up in it, and every other currency has a rate against it. Once you have documents it is locked, so that no total ever changes meaning.

Currencies

The app starts with the common currencies. Each one has:

  • Symbol text (such as USD) and Symbol (such as $).
  • Text: its full name.
  • Format: where the symbol goes, such as $123 or 123 €.
  • Sub unit: how many cents in one unit, 100 for most currencies.
  • Rate to your default currency: 1 USD = this many EUR. New invoices take this rate.

Archive the currencies you never use to keep pickers short.

Each invoice keeps its own rate

When you save an invoice in another currency, it keeps the rate of that day. Change the currency's rate next month and old invoices keep theirs: totals in your reports never move. You can also type a rate on one invoice only, such as the rate your bank actually gave you.

VAT in your currency

An invoice in another currency also prints its VAT in your default currency, with the rate used, as the EU VAT Directive (article 91) asks.

Seeing your money

The dashboard and every report show either one currency, or all currencies converted into yours, each at its own invoice's rate. Different currencies are never added up as they are. The Exchange rates used report lists the rate each document kept.
