Currency: USD. Invoice covers the listed completed work and approved charges.
These are illustrative agreed customer charges, not supplier costs or market-price guidance. The example assumes only the material line is taxable at 6%.
| Calculation or charge | Result |
|---|---|
| Concrete charge: 12 yd³ × $200 | $2,400.00 |
| Completed placement and finishing | $3,000.00 |
| Approved removal charge | $600.00 |
| Subtotal | $6,000.00 |
| Tax: $2,400 × 6% | $144.00 |
| Invoice total | $6,144.00 |
| Deposit received | $2,000.00 |
| Balance due | $4,144.00 |
A deposit reduces the amount still due; it does not reduce the value of the completed work. List it once under payments received so it is not also deducted as a negative charge.
An estimate describes expected work and pricing before a job starts. A quote states the proposed price and scope for acceptance. This invoice documents agreed charges for completed work and the payment still due. Changing a document heading alone does not record deposits, tax or due dates; those fields belong in the billing document.
Keep approved change orders identifiable. A line such as ‘Additional 200 ft² removal — approved September 12’ is easier to reconcile than a vague miscellaneous charge. Describe only work you can substantiate from your agreement and job records.
Your invoice rate is the agreed selling rate. It can differ from what you paid for concrete, labor or equipment. Putting internal supplier costs into the invoice by mistake can underbill the job and expose information you intended to keep private.
Enter all received deposits and payments in the payments field. If the customer has paid more than the invoice total, the preview shows an overpayment credit rather than a negative balance due. The tool does not collect payments, send reminders or maintain an accounting ledger.
The taxable checkbox allows mixed taxable and non-taxable lines. Confirm which charges are taxable and the correct rate for your location; this calculator applies your selections and does not determine tax obligations. Each line and the final tax are rounded to cents so the displayed charges reconcile.
Use a unique invoice number and a due date that follows the issue date. The Print / Save invoice as PDF button becomes available after required details and a positive valid total are present. Proofread the saved PDF, record it with your job paperwork and remove browser-added headers or footers in the print dialog if you do not want them.
Use this before the customer approves the work; return to the invoice tool when billing completed work.
Determine a sustainable selling price before agreeing to the charges you will invoice.
Check supplier costs before setting customer material charges.
