A freelance invoice should clearly show who is billing whom, what was provided, how much is due, when and how to pay, and, if you are VAT-registered, your VAT number. This guide gives general information for freelancers and sole traders in Ireland. It is not tax or legal advice.
If you are new to freelancing, invoicing can feel like a big step. In practice, an invoice is just a clear, professional request for payment. Getting the basics right helps you get paid faster and keeps your records tidy.
Key takeaways
- Include your details, your client’s details, a unique invoice number, the date, a description and the amount due.
- If you are registered for VAT, show your VAT number and the VAT charged. If you are not, do not charge VAT.
- Keep copies of every invoice you issue and every receipt you receive.
- Check Revenue (revenue.ie) for the current rules that apply to your situation.
What should an invoice contain?
Requirements differ depending on your situation, but most professional invoices include the following.
- The word «Invoice» and a unique invoice number. Numbers that run in order, such as 0001, 0002, 0003, make your records easy to follow.
- The invoice date. Many people also add the date the work or delivery took place.
- Your name or business name and your address, plus your email or phone number.
- Your client’s name and address.
- A description of the work or goods, with quantities, hours or unit prices where relevant.
- The amount due, in a clear currency such as euro.
- VAT details if applicable: your VAT number, the VAT rate and the VAT amount, and the total including VAT.
- Payment terms: the due date and how you accept payment.
- Bank details: your IBAN and BIC, with the account name.
VAT: when it appears on your invoice
VAT, or value added tax, is a tax on many goods and services. Whether you need to register depends on your business, the type of work and your turnover. Revenue sets these rules and they can change, so check the current details directly on the Revenue website instead of relying on a blog post.
What is helpful to know in general terms:
- If you are registered for VAT, you must usually show your VAT number on your invoices, and the amount of VAT charged.
- If you are not registered, you generally do not add VAT, and you do not show a VAT number.
- Different goods and services can have different VAT treatment. Some may be at a different rate, and some situations, especially with clients in other countries, may work differently.
- If you are unsure, ask Revenue or a qualified accountant.
Good practice that makes you look professional
Be clear about the work
A vague line like «Services» can lead to questions and delays. Write «Website design, 10 hours at the agreed rate» or «Translation of a 2,000-word document». If the client has a purchase order number, add it, because accounts departments often need it.
State your payment terms
Write the due date and what happens if payment is late. Many freelancers use terms such as payment within a number of days of the invoice date. Choose terms that you agreed with the client, ideally in writing at the start of the job.
Send it promptly
Invoice when the work is finished or at the milestones you agreed. The longer you wait, the longer you wait to be paid. Send the invoice as a PDF, so the layout stays the same on every device.
How to create your invoice
You can make an invoice in a word processor or spreadsheet, but a purpose-made tool saves time and avoids missing details. Use the invoice generator to enter your details, add line items and download a neat PDF. The information is processed in your browser, so your client names and amounts are not uploaded to a server.
If your client needs a signed copy, the sign PDF tool lets you add your signature to the finished file. If you want to send the invoice together with a timesheet or a report, you can combine them into one document with the merge PDF tool.
Keep good records
Invoices are only part of the picture. As a self-employed person, you generally need to keep records of your income and expenses, such as invoices you issue, receipts for costs, and bank statements. These records support your tax returns and protect you if Revenue asks questions.
- Save every invoice you send, including cancelled or corrected ones.
- Keep receipts for business expenses in one folder, on paper or digitally.
- Record payments when they arrive, and mark invoices as paid.
- Keep records for the period Revenue requires. Check the current length of time on revenue.ie.
A simple spreadsheet listing each invoice number, client, date, amount and payment status is already a strong start. Many freelancers also separate business and personal money by using a dedicated bank account.
Registering as self-employed
If you work for yourself in Ireland, you will usually need to register with Revenue for income tax purposes and file a tax return each year. Revenue’s website explains how to register, what taxes might apply and which deadlines to watch. Many freelancers find it helpful to speak to an accountant at least once, especially in the first year.
To summarise, a good invoice is clear, complete and easy to pay. Use the same template every time, number your invoices in order, keep copies, and check Revenue for anything you are unsure about. This guide is general information only, and your own situation may need advice from a qualified professional.
