What should I check before using the result?
Not an IRN/e-invoice or automatic tax-compliance check. Verify every mandatory local field before issuing.
Do free tools require an account?
No. Public UtilityHub tools open without an account. An account is required only when you want a workspace to save records, collaborate with a team or use paid product features.
Are the public tools really free?
Yes. The tools listed in the public tools directory are free to use. They do not start a subscription and do not ask for a card.
Are my files uploaded to UtilityHub?
Image and PDF pages state how each tool processes files. Where a page says browser processing, the work happens on your device. Always check the privacy note on the specific tool before adding a sensitive file.
Should I verify a downloaded result?
Yes. Open every downloaded file and confirm its dimensions, size, legibility and destination requirements. UtilityHub helps prepare a result but cannot verify the current rules of every external form or service.

Reproducible worked example
Milestone invoice with a clear due total
A consultant invoices one completed project milestone. The example separates the service value from tax so the amount due is easy to verify.
Example inputs
- Completed milestone
- $500
- Entered tax rate
- 10%
- Payment terms
- Due in 15 days
Replace these example values in the calculator or generator to reproduce the result.
Calculation
- Subtotal = 1 × $500 = $500
- Tax = $500 × 10% = $50
- Invoice total = $500 + $50 = $550
- Tax
- $50
- Amount due
- $550
What this shows: the issued amount follows directly from the described milestone and entered rate.
Assumptions
- The milestone has been completed and is ready to invoice.
- No earlier payment, credit note or withholding reduces the amount due.
Limits of the result
- The example does not establish local invoice or tax compliance.
- Payment status must be confirmed separately from the generated document.
Common uses
Product sales
Record quantities, unit prices, discounts and taxes.
Project milestones
Request an agreed stage or partial payment.
Recommended workflow
- 1Use a unique invoice number.
- 2Enter seller, customer and supply details.
- 3Review calculations, tax, due date and payment instructions.
- 4Download the PDF and keep the issued copy unchanged.
Questions
Can I turn a quotation into an invoice here?
The free generator creates a new document. Business OS supports a connected quotation-to-invoice workflow.
Does UtilityHub decide the applicable tax?
No. Enter and verify the rate and legal requirements that apply to your transaction.
Can I record partial payments?
Partial-payment tracking is available in the Business workspace, not the standalone generator.
