Mobile apps for field teams: offline, photos and sign-off

The features that make mobile apps for field teams work on site: offline mode, photos, checklists, signatures and syncing with the office.

Paper job sheets, photos lost in personal phones and invoices typed up after hours cost field teams hours every week. A good field app fixes that, but only if it’s built for real conditions on site.

The features that matter

Offline mode

Sites often have poor coverage. The app should keep working without signal and sync when it’s back.

Job details in one place

Address, customer, notes, history and safety information, available before the team arrives.

Photos attached to the job

Before-and-after photos saved straight to the job record, not someone’s camera roll.

Checklists and forms

Safety checks, inspection forms and compliance records filled in on the phone, with required fields so nothing is missed.

Customer sign-off

A signature on the screen when the job is done, with a copy emailed to the customer.

Time and materials

Hours and materials recorded as the job happens, ready for invoicing.

Sync with the office

Completed jobs flow back to the office, and invoices can be created in Xero automatically.

Buy or build?

Off-the-shelf job management apps suit many trades businesses. A custom app makes sense when your forms, workflows or reporting are specific to you, or you need it to connect with your own systems. Read custom software vs off-the-shelf to decide.

How it’s built

Most field apps are built cross-platform, so one app runs on iPhone and Android. See native vs cross-platform apps and what an app costs to build in NZ.

FAQ

Questions and answers

Straight answers to the questions we hear most. Can’t see yours? Ask us directly.

Still have questions?Talk to the people who build your project.
Can a field app work without mobile coverage?

Yes. With offline mode, the app stores job details, photos and forms on the device and syncs when it is back online.

Can a field app connect to Xero?

Yes. Completed jobs can create invoices in Xero automatically, so nothing is typed up after hours.

Should we buy a job management app or build our own?

If an existing app fits how you work, buy it. A custom app makes sense when your jobs, forms or processes are specific to your business.
