Free Invoice App for Small Business

Send the invoice before you leave the job.

Create an invoice, send it, and know the moment your client opens it. Use it free in any browser, or install the InvoiceSonic app on iPhone and iPad so you can invoice from the job before you get back in the van. Same account either way — start on your phone, finish on your laptop.

Free to start · No signup for your first invoice · iPhone & iPad app available

Browser or App Store — your choice — Use it free in any browser with nothing to install, or get the iOS app for iPhone and iPad. Your invoices, clients and settings sync across both.

What you get

Send in seconds

Build an invoice in the browser and email it straight to your client — no exporting, attaching or chasing files around.

Recurring invoices

Bill the same client weekly, fortnightly or monthly. Set it once and the invoice goes out on its own.

Automatic reminders

Overdue invoices get a polite nudge without you having to send the awkward message yourself.

See when it's opened

Know the moment a client views your invoice, so "I never got it" stops being a reason not to pay.

Your clients, saved

Client and item details are stored, so the second invoice takes seconds instead of starting from scratch.

Get paid your way

Put bank transfer, PayID, Venmo, Cash App, Zelle or PayPal on the invoice — including free rails so you keep 100%.

How it works

  1. 1

    Enter your details once

    Add your business name, ABN or tax number, and how you want to be paid. The app remembers it for every invoice after this one.

  2. 2

    Build the invoice

    Add your client and line items — totals, tax and GST calculate themselves as you type, so the maths is never wrong.

  3. 3

    Send it and track it

    Email it straight from the app or share a link. You'll see when it's opened, when it's due, and what's still outstanding.

Make your first invoice now

No signup needed to start. Create it, download it, and send it in about a minute.

Frequently asked questions

Is there a free invoice app?

Yes. InvoiceSonic is free to use — you can create and download professional invoices without paying anything, and without signing up to make your first one. A paid plan adds emailing, recurring invoices, reminders and payment tracking.

Do I need to download an invoice app?

Only if you want to. InvoiceSonic runs in any browser with nothing to install, and there is also a native iOS app for iPhone and iPad if you would rather invoice from your home screen. Both use the same account, so an invoice started on site can be finished at the desk. Android users can add the web app to their home screen and it behaves the same way.

What's the best invoice app for a small business?

The best one is the one you'll actually keep using. For most sole traders and small businesses that means: fast to create an invoice, easy to send, and it chases payment for you. Full accounting suites are more powerful but most small operators never use the extra features and pay three to four times as much.

Can I use the invoice app on my phone?

Yes. The app is built to work on a phone screen, so you can invoice from a job site or the car as soon as the work is done — which is when you're most likely to actually get it sent.

How much does it cost?

Creating and downloading invoices is free. Pro is A$19/month and adds emailing invoices, recurring billing, automatic reminders, payment tracking, your logo and branding, and client storage.
