Most ERPNext HR rollouts stall at the same place: the back office loves the ERP, but frontline and field employees never touch it. Filing a Leave Application, submitting an Expense Claim, checking a payslip or recording an Employee Checkin all mean logging into the ERPNext desk on a laptop or squinting at a responsive web view that was never designed for a phone. ERPNext HR is complete as a system of record, but out of the box it gives you no native mobile app, no push notifications for approvals, and no camera-first receipt capture or GPS-stamped attendance. That gap is where adoption dies and where HR ends up re-keying paper forms.

We build a branded native mobile app — your name, logo, colors and app-store listing — that sits on top of your existing ERPNext instance and talks to it through the Frappe REST API and a small set of @frappe.whitelist() server methods we ship as a proper Frappe app. Nothing is a separate database: a leave request from the phone creates a real Leave Application DocType record, respects your existing Leave Type, Leave Allocation and approval workflow, and flows through the same hooks.py doc events (on_submit, on_update) your ERPNext already runs. Expense claims capture receipt photos and attach them as File records against the Expense Claim; payslip viewing reads submitted Salary Slip documents scoped by permission; and check-in/out writes Employee Checkin rows with latitude/longitude, optional geofence validation and device time.

Technically the app authenticates each employee against their own ERPNext user, so every read and write is enforced by ERPNext's native role permissions and role profiles — an employee only ever sees their own records, and approvers see their queue. Push notifications for pending approvals are driven by Frappe scheduler_events and doc-event hooks that fan out to Firebase Cloud Messaging when a document needs a manager's action, so approvals happen from the lock screen instead of an unread email. Client-side validation mirrors the server rules, and all business logic that must be trusted lives in whitelisted methods and server scripts on ERPNext — the app is a thin, well-behaved client, not a second source of truth. We target Frappe/ERPNext v15 and v16.

Because this is build-to-order, we do not hand you a generic binary off a marketplace. After a short scoping call we confirm exactly which flows you need, your branding, your approval hierarchy and any custom fields, then design, build and test the app against a staging copy of your ERPNext. Typical delivery is 2 to 4 weeks from confirmed scope. You receive the full source code for your version, we install and configure the companion Frappe app on your instance, run UAT on staging with a documented rollback plan, and stay with you through a post-go-live support window. It is your app, your data and your ERPNext — we just make it reachable from every employee's pocket.
