Mistakes are easy to make—especially when you handle everything yourself as a freelancer. But your invoice is often the final touchpoint with your client and more important than you might think. An unclear or incorrect invoice can lead to payment delays or even distrust. Avoid these 5 pitfalls:

1. Vague descriptions

Something like “services rendered” means nothing to your client. Be specific: explain what you did, when, and for how long or for what fee. This avoids confusion or disputes.

2. Incorrect or missing details

Always check the name, address, and VAT number of your client. Your own details must also be accurate. A mistake here can cause the client’s finance department to reject your invoice.

3. Missing or duplicate invoice numbers

Every invoice must have a unique, sequential number. Duplicate or missing numbers create a messy administration and can lead to problems during an audit. Tools like InvoiceTimer automatically generate unique invoice numbers.

4. Incorrect VAT rates

If you apply the wrong VAT rate, you may have to correct it later—and even refund money. Make sure you know whether to apply 21%, 9%, or an exemption. InvoiceTimer calculates the correct VAT automatically.

5. Unclear payment instructions

Make it easy for your client: clearly state how and when they should pay. Include your IBAN, payment terms, and even a payment link or QR code. The easier it is, the faster you’ll get paid.

Avoid mistakes, save time
