What an invoice must include

An invoice is a request for payment for work you have delivered, so it should answer every question before the client has to ask it. Whatever the layout, make sure these are all present.

  • Your business name and contact details, and the client's billing details.
  • A unique invoice number and the issue date.
  • Itemized lines, each with a description, quantity or hours, rate and amount.
  • Subtotal, any taxes or discounts that apply, and the total due.
  • The due date and the payment terms.
  • How to pay: a payment link or your bank details.

Numbering your invoices

The invoice number is the label the client's accounts team uses to find, approve and pay the bill. Use a simple sequence such as INV-0001, INV-0002, a dated one such as 2026-0001, or a client prefix such as ACME-0001. Pick one format and keep to it.

Never reuse a number, never skip one on purpose, and pad with zeros so the list sorts properly. In a spreadsheet template, change the number in the file name and the document each time, because a duplicate is a common reason an invoice stalls.

Due dates and payment terms

Payment terms are the days the client has to pay, counted from the invoice date. Due on receipt suits small jobs and new clients. Net 14 is common for freelancers and small studios. Net 30 is the default for many established businesses. Longer terms such as net 45 or net 60 usually come from large companies and cost you cash flow.

Print the term and the exact due date on the invoice, and agree it in the proposal beforehand. Retainers are better billed on a fixed date each month than on net terms.

Late-payment reminders

Most late payments are not refusals. The invoice was missed, is waiting for approval or slipped down an inbox. A short, regular reminder routine fixes most of them without any awkwardness.

  • A few days before the due date, a friendly heads-up with the invoice number and a payment link.
  • On the due date, a brief note that payment is due today.
  • A few days after, a polite follow-up asking whether anything is blocking payment.
  • Later, a firmer message that restates the terms and any late fee you agreed in advance.

Reminders and late fees in Workspace369

Invoice template questions

Can I use a spreadsheet for invoices?

Yes. A spreadsheet works while you have a handful of invoices, as long as each one has a unique number and complete details. As volume grows, tracking what has been sent, paid and overdue by hand becomes the main cost, and that is when invoicing software helps.

What is the difference between an invoice and a receipt?

An invoice asks for payment and is issued before the client pays. A receipt confirms payment and is issued afterwards, showing what was paid, when and how. They usually share the same line items and invoice number so the records match.

How soon after the work should I send the invoice?

As soon as the work or milestone is delivered, or on the date you agreed for retainers. Sending the same day keeps the work fresh in the client's mind and starts the payment clock earlier, while a late invoice tends to be paid late.
