Most tradespeople learn invoicing by doing it wrong first. A scribbled note, a text message with a price, a verbal agreement that falls apart when the customer disputes what was included. A proper invoice prevents all of that and gets you paid faster.
Here is what every invoice should include and how to make the process as painless as possible.
What Must Be on Every Invoice
Your business name and address. If you are trading under a business name, use that. If you are trading in your own name, use your name. Include your address.
Your VAT number. If you are VAT registered, this is a legal requirement on all invoices. If you are not VAT registered, you cannot include a VAT number or charge VAT.
A unique invoice number. Number your invoices sequentially. This makes it easy to track which have been paid and to reference specific invoices in any follow-up.
The date. The date the invoice is issued, not the date the work was done.
The customer’s name and address. Full details, not just a first name.
A description of the work. Clear enough that there is no ambiguity about what was completed. “Exterior painting of front and rear of property at [address], including preparation and two coats of [product]” is better than “painting work”.
The amount. Show the net amount, the VAT amount separately if applicable, and the total including VAT.
Payment terms. When you expect to be paid. “Payment due within 14 days of invoice date” is standard for most trade work.
Your payment details. Your IBAN and BIC for bank transfer. Most Irish tradespeople are paid by bank transfer or cash. If you accept card payments, include that information too.
Send It Immediately
The single biggest change most tradespeople can make to improve their cash flow is sending invoices faster. Every day between completing a job and sending an invoice is a day added to when you get paid.
Get into the habit of sending the invoice the same day the job is complete, or the same day as agreed milestones on larger projects. If you cannot do it on the day, do it the morning after.
Follow Up Without Awkwardness
If an invoice goes past its due date without payment, follow up promptly. A brief, friendly message is enough: “Hi [name], just following up on invoice [number] for [amount], due on [date]. Let me know if you have any questions.”
Most late payments are the result of forgetfulness, not bad intent. A timely nudge usually resolves it without any awkwardness.
If payment is not made after two follow-ups, a more formal letter referencing your right to charge late payment interest under the Late Payment in Commercial Transactions Regulations tends to focus minds quickly.
Tools That Make Invoicing Easier
You do not need expensive software. A few options that work well for Irish tradespeople:
Surf Accounts. Irish-built accounting software with invoicing, VAT returns, and bank reconciliation. Good for sole traders and small businesses.
QuickBooks. Widely used, integrates with Irish banks, handles VAT returns.
Wave. Free invoicing and accounting software. Adequate for simpler setups.
Invoice Simple or Invoice Ninja. App-based invoicing for tradespeople who want to generate and send invoices from their phone on site.
Whatever you use, the important thing is consistency. A system you actually use beats a perfect system you never open.
