PayAbility · invoicing you own

Send an invoice in minutes. See who owes you at a glance.

Invoices, quotes, payment links and VAT reports, running from your own Google Sheet. Your clients and your numbers stay in your account. You pay once and there is no monthly fee.

Pay once. No subscription. 72 hour trial included. Make your own copy of the demo sheet, then start the 72 hour demo with the key INV-DEMO-2026.

Best for small businesses that invoice clients and want to see who owes them. It does not do stock control or payroll.

Most invoicing tools charge you every month, forever.

PayAbility is a module you deploy once. It lives in a Google Sheet that belongs to you, and you open it from one private link.

Owned, not rented

Pay once. If we vanish tomorrow, your system keeps working, because it runs in your own Google account.

Your data stays yours

Clients, invoices and payments are stored in your own spreadsheet. Nothing is copied to our servers.

Built for VAT

15% VAT, zero-rated and exempt lines, credit notes, and a VAT report you can work from when you do your return.

How it works

From purchase to your first invoice in three steps.

1

Copy the sheet

You receive your PayAbility sheet and licence key after payment.

2

Deploy it once

A short guide walks you through running setup and deploying it as a web app from your own account.

3

Open your private link

Bookmark one link. Every page, from invoices to reports, opens from there.

Questions

Short answers.

Do I need to know how to code?

No. Deploying is a handful of clicks and the guide shows each one. Choose Done with you and we do it together.

Where is my data stored?

In your own Google Sheet, in your own Google account. We never see your clients or invoices.

Is there a monthly fee?

No. You pay once. Sending email and generating PDFs use your own Google account.

Does it work for VAT vendors and non-vendors?

Both. You choose your tax settings, and zero-rated and exempt lines are supported.

Can I take my data with me?

Yes. Everything is already in your sheet, and you can export clients and invoices to CSV any time.

Can I try it first?

Yes. PayAbility includes a 72 hour trial, so you can create real invoices before you decide.

Is the VAT report accepted by SARS?

It is a working report to help you complete your return. Check it against your records or with your accountant before you submit.

Stop renting your invoicing.

Deploy PayAbility once and send your next invoice from a system you own.
