Invoice settings and numbering
Set your numbering scheme, default VAT rates, payment terms, logo and footer once, and every new invoice inherits them.
Last updated 25 July 2026
Everything on this page is a default. Temponia copies the tax rates, the tax names and the footer onto an invoice at the moment you create it, which means changing a setting here never rewrites invoices you have already issued. Numbering is the exception: the counter is shared and moves on with every invoice.
You find these settings under Company settings, on the Invoicing tab. The tab only exists when the invoicing module is on and you are an owner or admin.
Numbering
Invoice number prefix and Next invoice number together produce the number. The counter is padded to four digits, so a prefix of 2026- with a next number of 1 gives 2026-0001. An empty prefix is fine and gives you 0001.
The number is assigned when you create an invoice and leave the Number field blank. If you type a number yourself, that number is used as is and the counter is left alone.
Numbers are claimed one at a time, so two people creating an invoice at the same moment cannot end up with the same number. If the next number would collide with one you entered manually in the past, the counter jumps past the highest existing number instead of failing. Set Next invoice number by hand when you move to Temponia part way through a year and want to continue an existing series.
VAT and other taxes
Default tax takes a name and a percentage. The name is what appears on the invoice and in the PDF, so write what your country calls it: VAT, BTW, TVA, GST. The rate is the one applied to every line that does not override it.
Apply tax to expenses decides whether rebilled expenses are taxed. With it off, expense lines land on the invoice at 0% while time, fixed fees and retainer fees still carry the default rate.
Default tax 2 and Compound tax exist for places that levy two taxes on the same amount. The second tax applies to the whole taxable amount, and with Compound tax on it is calculated on the subtotal plus the first tax rather than on the subtotal alone. Leave both alone if you only charge one tax.
Second taxes and e-invoicing do not mix. A structured e-invoice cannot express a second tax or a compound tax. If you use either, Peppol sending refuses the invoice.
Individual invoice lines can override the rate. Every line has a VAT percentage in Edit invoice, and the invoice groups lines per rate and shows one VAT total per rate. Leaving a line's percentage blank makes it follow the invoice default.
Payment terms
Default due date offers Net 15, Net 30, Net 45, Net 60, Upon receipt and Custom. Automatically generated retainer invoices use this setting. On the New invoice form you pick the due date for that invoice yourself, so this default does not prefill it.
IBAN is printed under Payment details on the PDF, together with a line asking the client to pay by the due date quoting the invoice number. It is also the payment account carried on e-invoices. Leave it blank and the whole block is left off.
Appearance
Invoice logo takes a PNG or JPG and replaces the plain "Invoice" title at the top of the PDF and the web invoice. Once uploaded, a Current logo preview appears with a Remove logo checkbox next to it.
Accent color tints the invoice headings and the line above the total. It defaults to a dark grey, which is the neutral look; pick your brand colour if you would rather have one.
Default invoice footer is free text placed at the bottom of every new invoice. Payment instructions, a company registration number or terms of sale all belong here. Each invoice keeps its own copy of the footer, editable per invoice under Edit invoice.
Peppol address
Tucked behind the Peppol address summary is your identity on the Peppol network. In almost all cases you can ignore it: Temponia derives the address from the VAT number and country on your company info. The page shows you what it worked out. Fill in the scheme and identifier by hand only when your access point told you to use something different. See Peppol e-invoicing.
