A few useful
answers.

Do I need to download an app?

Open JobSums in your phone, tablet or computer browser. You can add it to your home screen using your browser’s options. An internet connection is needed to verify your access.

Can I use my own supplier prices?

Yes. Add materials manually or import an Excel or CSV price list into the pricebook. Prices come from the entries you maintain; a saved supplier account reference does not connect a live supplier feed.

Will my quotes appear on another phone?

Yes, when you sign in and enable Account saving. Jobs, build inputs, prices, business details and supported inventory save privately to your account, with ten previous versions available. Each new device asks you to choose its own copy or the account copy before connecting. Plan photos and supplier-order drafts stay on their device. Keep downloaded backups too.

Does JobSums approve a build against Australian Standards?

No. The current app provides limited checks and planning guidance. Structural design, member selection, fixings, local requirements and relevant Standards still need the appropriate checks and professional advice.
