| Field | Why it's there |
|---|---|
| From / Bill to | Who is billing and who is paying, with addresses and a contact |
| Invoice number | A unique ID, such as INV-1042, for your records and theirs |
| Issue date and due date | When you sent it and when payment is due (for example Net 30) |
| Line items | Description, quantity, unit, rate, and line amount |
| Discount, tax, shipping | Shown separately so the client can follow the math |
| Total and balance due | After any amount already paid or any deposit |

Worked example (the sample PDF)
Northwind Studio invoices Harbor & Pine Coffee Co. as INV-1042, issued November 10, 2026, Net 30 (due December 10, 2026).
| Line | Qty | Rate | Amount | Taxable |
|---|---|---|---|---|
| Brand identity refresh | 1 | $2,400.00 | $2,400.00 | Yes |
| Website design | 32 hr | $95.00 | $3,040.00 | Yes |
| Stock image licenses | 6 | $12.50 | $75.00 | No |
- Subtotal: $2,400 + $3,040 + $75 = $5,515.00
- Discount 5% of the subtotal: $275.75, leaving $5,239.25
- Tax is 8.25% on the taxable lines after the same 5% discount: taxable base = ($2,400 + $3,040) × 0.95 = $5,168.00; tax = $426.36
- Total and balance due: $5,515.00 − $275.75 + $426.36 = $5,665.61
The calculator above treats every line as taxable, so it will not match this sample unless you leave off the $75 non-taxable licenses (or set tax only on the taxable portion). The PDF generator used for the sample can mark individual lines as not taxable.
