How to use the Invoice Generator
- Add your business and customer details
- Add each item or service with a quantity and unit price, then add tax, a discount or shipping if needed
- Pick a template and check the live preview
- Use the Copy or Share buttons to save or send your result, or print / save it as a PDF.
Tip: Choose a profession preset first — it relabels the item fields and offers example line items so you're not starting from a blank table.
Common mistakes to avoid
- Leaving the tax rate blank when your jurisdiction requires one — the tool never guesses a rate for you.
- Setting a due date before the issue date, which makes the invoice confusing for the customer.
- Forgetting to mark items as non-taxable when only some of your line items should be taxed.
How invoice totals are calculated
subtotal → discount → tax → shipping → total → balance due
Each line item's total is quantity multiplied by unit price. Those line totals are added up into a subtotal. Your discount — either a percentage or a fixed amount — is subtracted from the subtotal next. Tax is then calculated only on the items you've marked as taxable, using the discounted amount, so a discount always reduces the tax you owe too, not just the pre-tax price. Shipping or any extra charge is added after tax, since it typically isn't part of the taxable goods or service. The result is your total. Subtracting anything the customer has already paid gives the balance due.
When to use this tool
Use it any time you need a one-off, itemized invoice — a single project, a service call, a freelance milestone, or a simple recurring bill — without opening spreadsheet or accounting software. It's built for speed: enter items, see the total and a print-ready preview instantly.
✓ Pros
- Works instantly, right in your browser
- Handles tax, discounts and shipping correctly, including edge cases like a 100% discount
- No sign-up, no ads blocking the result
✕ Limitations
- Does not convert between currencies — only formats the amount you enter
- Does not save invoice history or send emails on your behalf
- Does not know your local tax rate or legal requirements
Profession presets
the same engine, tuned for how you actually bill
The dropdown at the top of the tool switches between 11 profession presets. Each one adjusts the example line items and guidance to match how that trade typically bills, without changing how totals are calculated — the math underneath stays identical and fully tested.
| Profession | Typically bills for | Common extras |
|---|---|---|
| Contractor | Labor, materials, project milestones | Equipment rental, job address in notes |
| Freelancer | Hours or a fixed project fee | Milestone-based line items |
| Cleaning Service | Per-visit or recurring service | Supplies as a separate line item |
| Plumber | Service call, labor, parts | Emergency / after-hours fee |
| Electrician | Labor, materials, service call | Project-based multi-day jobs |
| Photographer | Session or package, travel | Editing as a separate line item |
| Consultant | Hourly or day rate | Reimbursable expenses as a line item |
| Handyman | Labor, materials, job description | Travel / service call fee |
| Landscaping | Labor, materials, one-off or recurring service | Seasonal/recurring notes |
| Web Designer | Design, development, milestones | Ongoing maintenance as a line item |
| Trucking | Load, pickup/delivery, mileage | Accessorial charges (detention, fuel surcharge) |
Tip: Picking a preset never overwrites items you've already entered — you'll always be offered an "Insert example items" button first.
Choosing an invoice template
All four templates share the exact same data and totals — switching between them is purely visual, so you can try each one against your brand without re-entering anything. Classic is a traditional, teal-accented layout. Modern uses a bold dark header band. Minimal strips styling back to clean typographic lines. Professional uses a double-rule header and a monospaced invoice number, closer to a formal accounting document.
Whichever template you pick, the exported version always renders on a plain white background with dark text — even if you're browsing TickmarkTools in dark mode — so the PDF or printout stays readable and professional.

Accuracy & limitations
This invoice generator is built for speed and correct math, but it's worth understanding what it does and doesn't do:
- Not legal or tax advice. It creates a professional invoice document, but invoicing, tax and record-keeping requirements vary by location and business circumstances. Verify applicable requirements with the relevant authority or a qualified professional.
- No currency conversion. Changing the currency only changes how amounts are formatted — it does not convert entered values between currencies.
- No saved history yet. Turning on "Remember my business info" saves your business details locally in this browser only; it does not save a history of past invoices or sync across devices.
