Invoice settings: logo, language, numbering, and reminders

Go to Invoices → ⋯ → Invoice settings. Here you set your invoice logo, the default invoice language, your invoice numbering, and when reminders go out. Save at the bottom applies your changes.

Logo

The logo that appears on your invoice PDFs. Upload, replace, or remove it. This is separate from the company logo on your dashboard, which lives under Company info.

Language

The language (Dutch or English) new invoices start in. You can still switch per invoice via Invoice language on the invoice itself.

Invoice numbering

Prefix (INV, for example), First number, and the number of Digits together build your invoice numbers; the preview shows the result, such as INV-2026-0001. Numbers are assigned when an invoice is issued, so a change applies to invoices issued afterwards — existing numbers never change.

Email reminders

Turn on Send reminders and AirBill emails your customer about outstanding invoices. Reminders are sent from your AirBill email address, so that has to be active first — see Set up and use your AirBill email address.

You pick the moments: 3 days before the due date, and 1, 7, or 14 days after. 30 days after is always on and then repeats monthly for as long as the invoice stays outstanding. The timeline under the choices shows which email belongs to which moment. Reminders stop by themselves once an invoice is Paid or Credited.

Common problems

Your logo doesn't show on an older invoice PDF

The PDF of an issued invoice is fixed. A new logo appears on invoices you issue afterwards.

You want a fixed language per customer

There’s no per-customer setting. The language here is the starting point; switch per invoice where needed.

The numbering doesn't continue from your old bookkeeping

Set First number to the next number from your previous package before issuing your first invoice.
