What to Include on a Professional Invoice
A proper invoice is a legal document that creates a record of the transaction between you and your client. Missing information on an invoice can delay payment, cause accounting issues, or create legal complications. Here is what every invoice should include:
Invoice Number
Each invoice needs a unique identifier. This makes it easy to track payments, refer back to specific invoices in communications, and organise your financial records. A simple sequential format (INV-001, INV-002) or date-based format (INV-2025-001) works well.
Invoice & Due Date
The invoice date establishes when the bill was issued. The due date tells the client when payment is expected. Common payment terms are Net 15 (15 days), Net 30 (30 days), or Due on Receipt. Clear dates reduce late payments.
Your Business Details
Include your full company name, address, email, and phone number. If you are VAT/GST registered, include your tax registration number. This lets clients contact you and gives them the information their accounting team needs to process the payment.
Client's Details (Bill To)
The full name or company name of who you are billing, their postal address, and their email. Some businesses require a Purchase Order (PO) number — add this in the notes or description field if needed.
Line Items
Each item or service provided should be listed separately with a description, quantity, unit rate, and line total. Itemised invoices are less likely to be disputed because the client can see exactly what they are being charged for.
Tax & Discount
If you are charging VAT, GST, or sales tax, list it separately as a percentage and amount. Discounts should also be itemised. This makes the invoice compliant with tax law and gives clients a transparent breakdown.
Total Amount Due
Make the total amount large and prominent. Clients should be able to see the amount they owe at a glance. Include the currency clearly — especially important for international invoices.
Payment Notes
Tell your clients how to pay. Include your bank account details, PayPal address, or any other accepted payment method in the notes section. Clear payment instructions significantly reduce the time it takes to receive payment.
Invoice Payment Terms — Which Are Best for Your Business?
Payment terms define when you expect to be paid after sending an invoice. Choosing the right terms for your business and your clients makes a big difference to your cash flow. Here are the most common invoice payment terms:
| Term | Meaning | Best for |
|---|---|---|
| Due on Receipt | Payment expected immediately | Small businesses, freelancers, new clients |
| Net 7 | Payment due within 7 days | Recurring clients, urgent work, small amounts |
| Net 15 | Payment due within 15 days | Standard service businesses, consultants |
| Net 30 | Payment due within 30 days | Most common term — used by most businesses |
| Net 60 | Payment due within 60 days | Large corporations, government contracts |
| 2/10 Net 30 | 2% discount if paid within 10 days, otherwise Net 30 | Incentivising early payment |
