Subscriptions change mid-cycle, add-ons get prorated, VAT rules shift by customer, and then the billing still has to go out clean. This invoices, payments and receipts template gives a SaaS invoice a fixed structure, so numbering, totals, and due dates don’t turn into a quarter of fixes and follow-up emails. The page uses deep teal accents with Lora headings and Inter body text, so the sections read like a checklist instead of a wall of text.

The invoice starts with Line items, which is where the bill gets built, then a payment terms block spells out when payment is due and what happens if the due date passes. The totals sit with that same section, so the customer sees the amount due next to the terms, not on a separate page... and the close lands on a short thank-you line that finishes the document without adding new conditions.

  • Line items The four placeholder entries are there to swap out for your own charges, proration, or plan credits before sending.
  • Payment is due on the date The payment terms appear in full, with a totals block alongside them, so the due date and amount due sit in the same place.
  • Thanks for trusting us with your billing A short closing line finishes the invoice after the terms, without adding extra conditions.

The template comes with four placeholder lines, so you replace the descriptions and prices, choose who it goes to, and send it. Online payment only applies if a payment method is connected, otherwise the invoice keeps the same layout and terms and goes out with your own payment details.

We went from spending hours on every proposal to creating fully customized ones in under 5 minutes. That's not an exaggeration - we timed it.

PartWhat it covers

Line items

The Line items section holds the billable entries, and the four lines provided are placeholders you replace with your own descriptions and prices.

Thanks for trusting us with your billing

The closing line ends the invoice after the terms, keeping the last thing the customer reads as an acknowledgement rather than another condition.

Questions about this invoice template

Can a SaaS invoice include VAT and other tax totals?

The template includes a totals block, so the invoice can show the totals due in the same place as the payment terms. Tax handling still depends on the figures you enter for the line items and totals you apply.

How do you avoid double-billing customers during a billing changeover?

A consistent invoice layout helps because every customer sees the same sections in the same order, which makes exceptions easier to spot before sending. The line items in this template are placeholders, so the main control is checking the descriptions and amounts you replace them with.

What should the payment terms say on a SaaS invoice?

The payment terms here say payment is due on the date shown above, ask the customer to pay using the payment details on the invoice, and note that late payment will be followed up under the terms. If different wording is needed, the terms section is a written block you can edit.

Do customers need online payment links on an invoice?

Online payment only applies if a payment method is connected. Without that, the invoice still goes out with the same line items, totals, and written payment terms, and the customer pays using the payment details shown on the invoice.

What happens if a customer disputes an invoice or asks for a credit note?

The invoice template includes the line items, totals, and payment terms, which gives a clear reference point for what was billed and when it was due. Credit notes and dispute handling aren’t covered in this invoice text, so those steps sit outside this document.

What does a SaaS invoice need to show so an accountant can reconcile it?

An accountant usually needs the billed line items, the totals due, and the payment terms, because those anchor what was charged and when it should be paid. This template keeps those parts together so the invoice reads the same way every time.
