Here’s the automated version. The hardest part of an hourly invoice is trustworthy hours. BizyClock tracks time against each client and job automatically, so the hours you bill are the hours you worked.
The terms line tells your client when payment is due. These are the standard options and where each one fits.
| Term | What it means | Payment due | Best for |
|---|---|---|---|
| Due on receipt | Payment is expected as soon as the invoice arrives | Immediately | One-off jobs, new clients, small amounts |
| Net 7 | Payment due 7 days after the invoice date | 7 days | Weekly-billed contractors and trades |
| Net 15 | Payment due 15 days after the invoice date | 15 days | Small businesses that need faster cash flow |
| Net 30 | Payment due 30 days after the invoice date | 30 days | The default for most B2B work |
| Net 60 | Payment due 60 days after the invoice date | 60 days | Large corporate and government clients |
| 2/10 Net 30 | 2% discount if paid within 10 days, otherwise the full amount in 30 | 10 or 30 days | Trading a small discount for faster payment |
| 50% deposit, balance on completion | Half up front, the rest when the work is delivered | Split | Long projects and material-heavy jobs |
| EOM | Payment due at the end of the month the invoice was issued | Month end | Clients who run a single monthly payment cycle |
Late-payment interest and mandatory terms vary by jurisdiction and contract — put whichever term you choose in writing before the work starts.
If you bill by the hour, an invoice is just structured hours × rate. This generator handles the layout, math, and formatting so you can send a professional-looking PDF in a couple of minutes — no template file, no spreadsheet wrangling.
From and bill-to details, invoice number and dates, itemized work, tax, totals, and payment terms in the notes. Choose your currency and the whole invoice formats to match.
The invoice is generated in your browser and downloaded straight to your device. Nothing is uploaded to a server or stored, so your client and rate details stay with you.
A polished invoice is only as good as the hours on it. Reconstructing billable time from memory costs freelancers real money. BizyClock records time against each client and job as you work, so your next invoice starts from accurate hours instead of guesswork.
List each piece of work as a line item with the quantity (hours) and your rate — the generator multiplies them into an amount. Add your business and client details, an invoice number and dates, and any tax, then download a clean PDF or a styled Excel workbook. The subtotal, tax, and total are calculated for you as you type, and the Excel version keeps those calculations as live formulas.
Yes, completely free with no account or email required. Your invoice is built entirely in your browser and downloaded directly to your device — nothing is uploaded or stored.
A professional invoice includes who it is from and who it is billed to, a unique invoice number, the invoice and due dates, itemized work with hours and rates, a subtotal, any tax, and the total due. Payment terms in the notes (for example "due within 14 days") help you get paid on time. This generator has fields for all of it.
Yes. Choose USD, CAD, GBP, EUR, or AUD and the amounts and totals — on screen and in the PDF — are formatted in that currency.
Billing from memory or scattered notes is where hourly invoices leak money. Tracking time against each client or job as you work gives you exact billable hours to drop straight onto the invoice. BizyClock records that time automatically and ties it to jobs, so the hours you bill match the work you did.
