Worked sample: three-line invoice| Line | Amount |
|---|
| Brand style guide | $1,200.00 |
| Landing page design | $850.00 |
| Revision rounds, 2 × $150 | $300.00 |
| Subtotal | $2,350.00 |
| Tax at 8.25% | $193.88 |
| Total due | $2,543.88 |
Those figures match the tool above exactly. Change any number and watch the totals move. The tax field accepts any percentage you need.
How should you number your invoices?
Sequential numbers keep records clean.
Simple counting works at small volume. Try 001, 002, 003, and upward. Never reuse a number after a cancellation.
Year-based numbers sort better across years. A format like INV-2026-014 groups by year. Auditors read number gaps as missing records.
Log every number in one place. A ledger or spreadsheet both work. The habit saves hours at tax time.
Which payment terms get you paid faster?
Terms set the clock before anything else.
Net 30 means payment is due 30 days after issue. It remains the most common standard. Late fees of 1% monthly create gentle urgency.
Common payment terms explained| Term | Meaning | Best for |
|---|
| Due on receipt | Pay immediately | Quick tasks |
| Net 15 | Due in 15 days | Small projects |
| Net 30 | Due in 30 days | Standard work |
| Net 60 | Due in 60 days | Corporate clients |
Pick one term and stick with it. Mixed terms confuse both bookkeeping teams. State the term on every invoice you send.
How do taxes and the 1099-NEC threshold work?
Two tax facts touch your invoices.
Most services escape sales tax, but rules vary by state. Goods and some digital products get taxed. Ask an accountant before adding tax lines across state lines.
Clients send a 1099-NEC after $2,000 of payments in 2026. (IRS, 2026) The old $600 threshold ended with 2025. Keep invoices anyway, because your tax return needs every total.
Self-employed workers also owe quarterly estimates in most cases. Set aside roughly 25% to 30% of each invoice for taxes. The exact figure depends on your bracket and state.
Why send invoices under a business name?
A business name builds trust on the bill.
A single-member LLC separates business money from personal money. Invoicing under the LLC name keeps that wall strong. Our operating agreement guide explains the paperwork.
Setting up in Texas? Our Texas LLC walkthrough covers every filing step. Clients also take invoices more seriously with a business name.
Open a business bank account once the LLC exists. Deposit every invoice payment there. The paper trail protects your liability shield.
What can this generator not do?
Honest limits build honest tools.
It does not chase unpaid invoices or send reminders. It does not compute your state sales tax. Accounting software handles those jobs.
It produces a clean, professional document fast. That document starts every payment conversation. Finish it, send it, and log the number.
How do you download or print the invoice?
The download button builds a Word file in your browser. The print button opens your system print dialog.
Choose "Save as PDF" there for a PDF copy. Both outputs carry no watermark. No account or email is required at any step.
Next steps
