Questions

Before you ask.

Where is my data kept?

In a hosted database with daily backups, plus our own off-site copy, because SARS expects you to keep records for five years. The demo is different: it stores nothing on a server.

What about POPIA?

Your helpers' ID numbers and your customers' details are personal information. We process them for you as an operator under POPIA, under a written operator agreement that forms part of our terms.

Does it replace my accountant or Sage/Xero?

No. It handles quoting, job costs, helpers and travel during the month, then gives your accountant clean CSV exports. Many clients keep their accounting package as well.

Can it do VAT?

Yes. One setting switches on 15% VAT and tax-invoice wording when your company registers.

Do I need an app?

No. It runs in the browser on any phone, tablet or computer. Sign in with a code sent to your email.

Are the tax figures advice?

No. The minimum wage, PAYE flag and km rate are checks to prompt a question, updated each March. Confirm anything that matters with your accountant.
