Getting paid on time is the lifeblood of a small business. Yet many business owners lose thousands of dollars each year to late payments, simply because their invoicing process has gaps. This guide covers everything you need to know.
What Every Invoice Must Include
Regardless of your country, a valid business invoice typically requires:
- Your business name and address
- Your business registration or tax number (GST/HST number for Canada, VAT number for UK/EU)
- Invoice number — unique, sequential (e.g., INV-0047)
- Invoice date and payment due date
- Client name and billing address
- Itemised list of goods or services with quantities and prices
- Subtotal, tax amount, and total
- Payment instructions — bank details, payment link, or address to mail a cheque
Missing any of these can delay payment or cause issues with your client's accounts payable team.
How to Get Paid 30% Faster
Research from FreshBooks and other accounting platforms consistently shows that businesses using the following tactics get paid significantly faster:
1. Send Invoices Immediately
Don't batch invoices at month-end. Send the invoice the same day you complete work or deliver goods. The longer you wait, the lower it sits on your client's priority list.
2. Offer Online Payment
Invoices with a Pay Now button get paid an average of 8 days faster than those without. Integrate Stripe, PayPal, or Square so clients can pay with a credit card in under 60 seconds.
3. Set Clear Payment Terms
Be explicit: "Payment due within 14 days of invoice date." Vague terms like "payment upon receipt" lead to confusion.
4. Send Automatic Reminders
Set up automated email reminders:
- 3 days before due date: friendly heads-up
- On due date: polite nudge
- 7 days overdue: more formal notice with late fee warning
5. Add Late Payment Fees
Include a late payment clause: "A 1.5% monthly interest charge applies to balances outstanding beyond 30 days." Many clients will pay on time purely to avoid the fee.
6. Invoice in the Client's Currency
If you work with international clients, consider invoicing in their local currency. The exchange rate risk is real, but the convenience to the client often results in faster payment.
Common Invoicing Mistakes to Avoid
Mistake 1: No invoice number sequence Sequential invoice numbers are required by most tax authorities and make it easy to track outstanding invoices.
Mistake 2: Not following up 41% of small business invoices are paid late. Following up is not rude — it's essential.
Mistake 3: Wrong tax rates Using the wrong GST/HST rate (e.g., charging 5% GST when you should charge 13% HST to an Ontario client) can lead to audits and penalties.
Mistake 4: Forgetting to record payments If a client pays and you don't mark the invoice as paid, your P&L will show incorrect revenue figures and you'll chase a client who's already paid.
