We develop native iOS (Swift) and Android (Kotlin) apps for field sales, service, warehouse and dealer teams. Each app connects to the ERP or web system you already run, so a record entered on site appears at head office straight away. The app keeps working offline, scans barcodes and captures photos and customer signatures. We handle store publishing too.
Orders written in a notebook, service reports handed in at the end of the day, stock counts copied from paper into Excel: by the time the information reaches the office it is hours or days old, and re-keying has added errors along the way. Managers find out what was sold or finished only the next morning.
A custom mobile app removes that delay: data is captured once on site and written straight into your ERP or web system, never typed twice. Where there is no signal the app keeps working and syncs once it reconnects.
Native Swift development for iPhone and iPad. We handle App Store submission and ongoing releases.
Native Kotlin development for Android phones, tablets and handheld terminals. Google Play publishing and release management included.
No back-office system behind the app yet? We build that as well: see custom web software, field service management, warehouse and inventory management and API integration.
Most often field sales, dealer and customer ordering, service and maintenance, warehouse and logistics, and management dashboard apps. The common goal is to get information that would otherwise be written on paper to head office as soon as it is captured. For one food distributor, more than 70 dealers now order by phone against their own prices and live stock, with orders flowing into the ERP automatically.
We build natively: Swift for iPhone and iPad, Kotlin for Android phones, tablets and handheld terminals. The apps use device features such as barcode and QR scanning with the camera, GPS location, and sign-in with Face ID or fingerprint. We also handle App Store and Google Play submission and ongoing releases, so you do not have to manage the store process yourself.
Yes. The app is built connected to the ERP or web system you already run; data captured on site is written straight into it and never typed twice. If there is no back-office system behind the app yet, we build that as well, whether custom web software, field service management or warehouse and inventory management, and link the systems through API integration.
Yes. In basements, on building sites or in rural areas the app keeps working without a signal. Orders, work orders, photos and signatures are stored on the device and synchronised automatically once a connection returns. Field teams working in poor-coverage areas therefore do not fall back on paper forms, and no data is lost in the meantime.
Offline mode, push notifications for new jobs and approval requests, barcode and QR scanning with the phone camera, GPS location and maps for visit logging and routing, quick sign-in with Face ID or fingerprint, on-screen customer signatures with an automatically generated PDF, and photos attached directly to the relevant record. We decide together which of these your workflow actually needs.
