Contact us

The quickest way to reach InvoiceMakerHQ is by email at hello@whizinvoice.com. Write to us about a problem with a tool, a fact you think is wrong, a feature you would like, or your data. A person on the team reads every message, and a contact form on this page is coming soon.

Email us

Send your message to hello@whizinvoice.com. That one address covers everything: help with the tools, corrections to guides, privacy requests and general questions. We aim to reply within a few working days, and sooner when something on the site is broken.

A contact form is on its way. Until it is ready, email is the only way to reach us, and we do not take calls.

What to include in your message

A little detail saves a round of back and forth. The more precisely you describe what you saw, the faster we can fix it or answer. You do not need to send us any invoice data to report a problem, and please do not include bank details or passwords.

  • A tool problem: the page address, your browser and device, what you did, and what happened instead of what you expected. A screenshot helps.
  • A correction: the page, the sentence that looks wrong, and a link to the official source that shows the right figure.
  • A privacy request: the email address you used with Email me, and whether you want your details deleted or a copy of them.
  • An idea: what you were trying to do and where the tool got in your way.

What we cannot help with

We can explain how our tools work and point you to the official guidance we used, but we cannot give tax or legal advice for your situation. For questions such as whether you must register for GST or VAT, ask your tax office or a qualified adviser.

We also cannot see or recover invoices you made here, because they are stored only in your browser. If you cleared your browser data, the saved copies are gone, so keep the PDFs you download.

Questions, answered.

Short answers first. Something missing? Ask us.

How quickly will you reply?

We aim to reply within a few working days. Reports that a tool is broken or a figure is wrong go to the front of the queue, because they affect other people’s invoices too. If you have not heard back within a week, send a short follow up in case your message was filtered.

Can you find an invoice I made last month?

No. Invoices you make here are saved only in your own browser, so we never receive them. Open the same browser on the same device and look in your saved invoices, which hold the last 20. If you downloaded the PDF, check your downloads folder.
