Who it is for: For shops, stores and service businesses that issue invoices every day.

Sample invoice form: lines are added, and tax and the grand total are calculated automatically.

Your own tax rates

You define the rates and each line can use a different one. We are not tied to any one country’s tax system.

Instalments and down payments

Split an invoice into instalments and choose which account receives the down payment. Instalment due dates appear in the calendar.

Status at a glance

Open, partly paid, paid and overdue badges show which invoice is waiting.

What is in this module?

  • Sales and purchase invoices

    Both work in the same layout, with separate number series.

  • Product or free-text lines

    Pick a product from stock or type one by hand. Line discounts and an overall discount can be applied.

  • Your own tax rates

    A separate rate for each line. You add, edit and pick the default rate in settings.

  • Tax withholding

    On invoices with tax withheld at source, you enter the withholding rate and the amount payable is shown separately. If you do not use it, turn it off in settings; while it is off, it does not appear on new documents.

  • Automatic numbering

    The number is assigned when you save and never clashes. You choose its format from document series.

  • Due-date suggestion

    Payment days come from the customer’s card, or from company settings if there are none. You can change them on the invoice.

  • Foreign-currency price

    Enter a line with currency and rate, and the equivalent in your base currency is calculated.

  • Instalments and down payment

    Type the number of instalments and preview the due dates and amounts. The rounding remainder is added to the last instalment.

  • Collection with the invoice

    If the invoice was paid on the spot, you record the collection or payment on the same screen.

  • Advance deducted automatically

    Amounts of the customer not linked to an invoice are deducted from a new invoice automatically.

  • Approval and cancellation

    An approved invoice cannot be changed. It is cancelled, and linked collections stay as advances.

    Copy an old invoice to open a new one.

  • Default invoice terms

    Payment and delivery terms come from settings and can be edited on the invoice.

  • Link to a project

Frequently asked

Can I change an approved invoice?

No. To keep records trustworthy, an approved invoice cannot change. If there is a mistake you cancel it and issue the correct one; the cancellation stays on record. The “Copy as new” button speeds this up.

What happens to a linked collection if I cancel the invoice?

The collection is not deleted. It stays as an amount not linked to an invoice (advance) and shows in the customer’s balance.
