Quoting & invoicing built for aircon & HVAC in South Africa
Supply-and-install or a regas and service — price the unit, brackets and labour, take a deposit, and invoice before you leave the roof.
The fastest quote wins the job
The aircon technician who sends a proper quote first looks the most professional — and gets the work.
The old way
You order the unit on the customer’s word, install it, and then spend a week chasing the balance with nothing in writing.
With BlitzBooks
A clear quote with a deposit for the unit, and a tax invoice handed over the moment the system’s blowing cold.
Three taps from quote to cash

The bits aircon & hvac technicians ask about
Can I invoice a service call quickly?
Yes. Raise an invoice directly for a service, regas or repair — itemised, VAT added, sent in seconds.
Can I keep track of repeat service clients?
Yes. Every client’s details and full job history are saved, so a returning customer is one tap away.
Do I need a card to start?
Yes. A card starts the 7-day free trial. We check it with R1 and refund it straight away, so nothing is charged today. If you keep going it is R200 a month from the day the trial ends. Cancel in Settings before then and you pay nothing.
Will it work on my phone?
Yes — any modern iPhone or Android, plus desktop. Add it to your home screen and it runs full screen like a normal app.
