Invoice Tracking Spreadsheet: Free Template + When to Automate
A spreadsheet is the first tool most freelancers use to track invoices. It's free, flexible, and works well — until a client stops paying. Here's a free template to track everything, plus an honest look at what spreadsheets can't do.
Recommended columns for your invoice tracker
| Col | Header | Example | Notes |
|---|---|---|---|
| A | Invoice # | INV-042 | Sequential. Required by HMRC/IRS. |
| B | Client Name | Acme Corp | Full legal name of the client. |
| C | Invoice Date | 2026-05-01 | Date you sent the invoice. |
| D | Due Date | 2026-05-15 | Invoice date + your payment terms. |
| E | Amount (net) | £2,500 | Before tax. |
| F | Tax / VAT | £500 | If applicable. |
| G | Total Due | £3,000 | Formula: =E+F |
| H | Status | Overdue | Dropdown: Unpaid / Paid / Overdue / Disputed |
| I | Days Overdue | 14 | Formula: =IF(H2='Paid','',TODAY()-D2) |
| J | Last Follow-up | 2026-05-10 | Date of your last chase email. |
| K | Notes | Client said 'will pay by Friday' | Freetext. |
Useful formulas
Days overdue (0 if paid)
=IF(H2="Paid",0,MAX(0,TODAY()-D2))
Total unpaid
=SUMIF(H:H,"Unpaid",G:G)+SUMIF(H:H,"Overdue",G:G)
Total overdue (30+ days)
=SUMPRODUCT((I2:I100>=30)*(G2:G100))
Conditional formatting — red if overdue
Custom rule: =AND(I2>0,H2<>"Paid")
What a spreadsheet can't do
A spreadsheet is great for visibility. It will show you what's overdue in red. It will calculate totals. But there are four things it fundamentally cannot do:
The real cost of spreadsheet tracking
The spreadsheet shows you what's overdue. But seeing it and doing something about it are two different things. Here's what typically happens:
When to use a spreadsheet vs. automated tools
Spreadsheet is fine if:
- ✓ Under 5 active invoices at a time
- ✓ All your clients pay reliably
- ✓ You're just starting out
- ✓ You have time to follow up manually
Automate when:
- ✓ You have 5+ invoices per month
- ✓ Any clients pay late
- ✓ You're spending 30+ min/week on follow-up
- ✓ You want to be paid faster
