Last-Mile Driver & Proof-of-Delivery App for ERPNext

Key Features

Reads each driver's assigned `Delivery Trip` and `Delivery Stop` child rows over the Frappe REST API so the mobile manifest is the same submitted record the back office sees

Turn-by-turn navigation launched from each stop's stored geolocation, with stops ordered by the trip's planned sequence

On-glass e-signature capture plus one or more delivery photos, persisted as Frappe `File` attachments linked to a POD DocType

Structured failed-delivery reason codes backed by a reason-code master DocType (customer absent, refused, wrong address, damaged, rescheduled) instead of free text

COD collection recorded per stop, rolled into a driver cash-session DocType and reconciled at handover with an explicit variance line

`hooks.py` doc events on POD submit stamp the linked `Delivery Note`/`Sales Order` and advance delivery status automatically

Whitelisted server methods (`frappe.whitelist()`) expose only the driver-scoped actions the mobile client needs — no broad table access

Live location and stop status pushed to the back office via server scripts and scheduler events, with optional customer/dispatcher notifications

Dedicated `Delivery Driver` role profile and permission rules so a driver sees only their own trips, stops and cash sessions

Offline-tolerant capture: signatures, photos and COD entries queue on-device and sync when connectivity returns

GPS coordinates and server timestamp stamped on every delivery and failed attempt for dispute resolution and audit

Configurable stop lifecycle (assigned → en route → arrived → delivered/failed) implemented as controlled status transitions

Back-office dashboard and report views over POD records, reason-code breakdown and COD variance built on Frappe report/query tools

Built and tested against Frappe/ERPNext v15 and v16, following framework conventions so it survives `bench update` and site migrations

About this Product

Field-delivery teams running on ERPNext hit the same wall: the Delivery Trip DocType is a solid back-office plan, but it stops at the warehouse door. Drivers still work from printed manifests or WhatsApp messages, proof of delivery arrives as a shoebox of paper signatures, and cash-on-delivery money is reconciled by memory at end of day. ERPNext core has no driver-facing mobile surface, no structured capture of who received a parcel, and no way to know in real time whether stop 7 of 12 succeeded or failed. That gap is exactly where deliveries leak — disputed drop-offs, unaccounted COD cash, and a back office that is blind until the van returns.

We build a proper Frappe app — installed on your own bench alongside ERPNext — that adds a mobile-first driver workflow on top of the objects you already use. The app reads each driver's assigned Delivery Trip and its Delivery Stop child rows through the Frappe REST API and whitelisted methods (frappe.whitelist()), so the manifest a driver sees is the same record accounting and inventory see. Each stop links back to its Delivery Note and Sales Order, launches turn-by-turn navigation via the stop's geolocation, and on arrival captures a structured proof of delivery: an on-glass e-signature, one or more photos stored as File attachments, the receiver's name, and a timestamp with GPS coordinates. Failed attempts are recorded against a configurable set of reason codes (customer absent, refused, wrong address, damaged) rather than a free-text guess, so exceptions become reportable data instead of anecdotes.

Technically, the app ships as a versioned Frappe module with its own DocTypes (for POD records, reason-code masters, and COD cash sessions), hooks.py document events that fire on submit to stamp the linked Delivery Note and post the delivery status back, and client scripts that drive the on-device capture flow. COD collection is first-class: each cash payment is recorded against the stop, rolled into a driver cash session, and reconciled at handover so the amount received matches the amount banked — with a clear variance if it does not. Server scripts and scheduler events push live location and stop status to the back office and can trigger notifications, while Frappe's permission model and role profiles (a Delivery Driver role that sees only its own trips) keep drivers scoped to their own data. The build targets Frappe/ERPNext v15 and v16 and follows framework conventions throughout, so it survives bench update and standard site migrations.

Because this is build-to-order, nothing is a black box you download blind. After a short scoping call we confirm your exact stop lifecycle, reason codes, COD rules, and role model, then build against that specification. You receive the full installable source, we install and configure it on your staging site, you sign off through UAT, and we deploy to production with a rollback plan. Typical delivery is 2 to 4 weeks from confirmed scope, and you own the git repository at the end.

Who this is for

Logistics / Dispatch Manager

Runs daily delivery trips in ERPNext and needs real-time visibility into which stops succeeded, which failed and why, without waiting for the van to return. Buys this to replace paper manifests and phone check-ins with live, reportable status.

Finance / Accounts Controller

Owns COD cash integrity. Needs every cash-on-delivery collection recorded against the stop, rolled into a driver session, and reconciled at handover so banked cash matches collected cash with a clear variance trail.

Operations / IT Lead on ERPNext

Maintains the company's ERPNext bench and wants a driver app built as a clean Frappe module — proper DocTypes, hooks and permissions — that survives bench updates rather than a fragile external integration or spreadsheet workaround.

Field Delivery Team Lead

Manages the drivers themselves and needs a simple mobile flow: see my stops, navigate, capture signature and photo, log a failure reason, take COD. Buys this so drivers stop juggling WhatsApp, printouts and cash notes.

How Last-Mile Driver & Proof-of-Delivery App for ERPNext Compares

Criterion	ECOSIRE	Custom Build	Competitor	ERPNext Native
Fit to your delivery workflow	Built to your exact stop lifecycle, reason codes and COD rules	Fully bespoke but you carry all design decisions	Fixed feature set; you adapt to its assumptions	Delivery Trip only — no driver mobile flow

COD cash reconciliation	Per-stop capture, driver cash session, variance at handover	Build it yourself from scratch	Basic COD flag, rarely reconciled	Not handled by core
ERPNext integration depth	Native Frappe module: DocTypes, hooks.py events, whitelisted API	Depends on your team's Frappe skill	Frequently an external app syncing over API	N/A
Version safety (v15/v16)	Framework-conventional, survives bench update; upgrade guidance included	Only as disciplined as your build	Depends on vendor's upgrade cadence	Maintained by ERPNext core
Delivery time & cost	2–4 weeks from confirmed scope, fixed quote	Longer; open-ended internal effort	Instant install but rework to fit	Free but does the job only partway
Code ownership	Full source + git repo handover, no lock-in	You own it outright	Usually closed source / licensed	Open source core
Support after go-live	Included support window + optional retainer	Your team supports it	Vendor SLA, variable quality	Community / your own ERPNext partner

Frequently Asked Questions about Last-Mile Driver & Proof-of-Delivery App for ERPNext

Is this an existing app I can download and install today?

No. This is a build-to-order app that ECOSIRE builds, installs and supports for your specific workflow. It is not an off-the-shelf Frappe Cloud Marketplace download — we scope your stop lifecycle, reason codes, COD rules and roles first, then build against that specification.

How long does delivery take?

Typical delivery is 2 to 4 weeks from confirmed scope. The clock starts once we have agreed the requirements in writing after the scoping call — not from the day you enquire. Larger or heavily customised builds are estimated during scoping.

Which versions of ERPNext does it support?

We build and test against Frappe/ERPNext v15 and v16, following framework conventions (proper DocTypes, hooks.py doc events, whitelisted methods, permissions) so the app survives `bench update` and standard site migrations. Tell us your exact version during scoping.

How does it fit with the native Delivery Trip and Delivery Note?

It builds directly on them. The driver app reads the assigned `Delivery Trip` and its `Delivery Stop` rows via the Frappe REST API, and on proof-of-delivery submit, `hooks.py` doc events stamp the linked `Delivery Note`/`Sales Order` and advance status. Your existing ERPNext data stays the source of truth.

How is COD cash reconciled?

Each COD payment is recorded against its stop and rolled into a driver cash-session DocType. At handover the app compares total collected against total banked and shows an explicit variance, so finance gets an auditable trail instead of end-of-day estimates.

What about support and updates after go-live?

Every build includes a post-go-live support window for defect fixes and configuration questions, plus full git repository handover so your team can maintain it. Ongoing enhancements, new features or version upgrades beyond the window are available as a separate support/retainer arrangement.

Do we own the code?

Yes. You receive the full installable source and the git repository is handed over to you, so you are never locked in. You can maintain, extend or re-host the app with your own team or another vendor.
