Sound familiar?

Built for HVAC firms.

Less paperwork and Excel, more time for installations and servicing.

Writing quotes at night?

Pick items from your price list, enter quantities and the quote is done. In 5 minutes, even from your phone on site.

Paying for equipment out of your own pocket?

Create an advance invoice as a percentage. AdBooks calculates the amount and VAT and deducts it from the final invoice by itself.

Extra work with no paper trail?

Record every extra job in the project and invoice it separately, so there is no argument about what was agreed.

Client paying late?

A reminder before the due date and three reminders after go out automatically, in the language of the document. You do not have to call.

The Estimator (Growth and Booster plans) has a ready-made catalogue of items by trade. On top of that you save your own items and prices and reuse them in every quote.

Yes. Save your items and services with prices once and use them in every quote. You can also import customers and products from a CSV file.

Extra work that was not in the first quote is tracked inside the same project and invoiced separately, so the client sees exactly what was added and why.

Yes. AdBooks runs in the browser on your phone and you can add it to the home screen like an app. Create and send the quote on site, and the client signs it on their own phone.

With every invoice AdBooks also creates an e-invoice in Peppol UBL 2.1 format (EN 16931). National fiscalisation or clearance systems are not supported, so check with your accountant what applies in your country.
