Mobile apps for POS and e-invoicing

Your team needs to charge and invoice from a phone without spreadsheets or a clunky web POS. I deliver native or hybrid mobile apps connected to your backend: Jetpack Compose Android, React Native, online payments, and integrated e-invoicing.

Ideal for
Retailers, distributors, and SMBs that need mobile POS, field sales, or e-invoicing from tablet or phone.
Typical timeline
A mobile POS app with API backend is typically delivered in 8 to 14 weeks, depending on offline, payments, and e-invoicing.

The challenge

Your team sells in-store or in the field but relies on spreadsheets, WhatsApp, or a web POS that works poorly on phones and does not issue e-invoices on the spot.

What you get

Native or hybrid apps (Android with Jetpack Compose, React Native) connected to your ERP/POS, online payments, and electronic invoicing from the device.

Frequently asked questions

Native or React Native for a POS?

Pure Android with Jetpack Compose when the device is fixed (tablet/register) and performance matters most. React Native when the team uses both iOS and Android in the field and time-to-market is key.

Does the app issue e-invoices by itself?

The app triggers the sale; the Laravel backend validates, queues, and issues the e-invoice with the PAC. Fiscal rules and credentials stay off the device.

Does it work offline?

Limited offline mode (catalog, cart, queued sales) with sync when back online can be designed. Offline scope is defined in discovery based on your operations.
