India GST Compliance & E-Invoice Suite

Key Features

Automated e-invoice IRN generation against the NIC IRP, triggered from the Sales Invoice `on_submit` doc event via `hooks.py`, with IRN, acknowledgement number, and signed payload persisted to an `E-Invoice Log` DocType

Mandated QR code and IRN rendered on the customer invoice through a dedicated ERPNext print format

E-invoice cancellation within the statutory window, wired to `on_cancel` and mirrored to the IRP with reason codes

E-waybill generation, Part-B updates, and extension/cancellation handled through whitelisted server methods and logged in an `E-Waybill Log` DocType

Real-time GSTIN verification against the government/GSP API via a client script on Customer, Supplier, and Address, plus a bulk re-validation job

Scheduled GSTR-2A/2B pull through a `scheduler_events` background job that stages inward-supply data for matching

GSTR-1 outward-supply preparation and export in the government-prescribed JSON/schema for portal upload

Purchase reconciliation engine matching booked Purchase Invoices to GSTR-2B with configurable tolerance on GSTIN, invoice number, date, and taxable value

ITC-matching workflow that flags matched, mismatched, missing-in-books, and missing-in-portal lines for your tax team to action

GSP/ASP credential handling isolated behind server-side whitelisted methods, never exposed to the browser, with token refresh managed automatically

DocType permissions and Role Profiles scoping IRP actions, cancellations, and reconciliation sign-off to authorised finance roles

Idempotent API calls with retry and duplicate-IRN guard so a re-submit or network failure never double-registers an invoice

Frappe REST API endpoints so IRN status, e-waybill numbers, and reconciliation results are consumable by external dashboards or logistics systems

Compatibility with Frappe/ERPNext v15 and v16, packaged as a standard installable Frappe app with clean migrations

About this Product

Indian GST-registered businesses on ERPNext hit a wall the moment compliance moves beyond printing a GST-formatted invoice. Sales Invoices above the e-invoicing turnover threshold must be registered with the NIC Invoice Registration Portal (IRP) to obtain an IRN and signed QR code before they are legally valid; goods movements need e-waybills raised and updated in near real time; every purchase must be reconciled against auto-drafted GSTR-2A/2B data before you can safely claim input tax credit (ITC). ERPNext core carries the GST tax scaffolding and the official india_compliance app covers a good baseline, but most finance teams still find gaps around bulk IRN handling, e-waybill edge cases, GSTIN re-verification on master changes, and a reconciliation workflow that matches their actual vendor behaviour and ITC policy. That manual glue is where errors, blocked credit, and filing delays creep in.

We build a proper Frappe app that layers the missing automation directly onto your ERPNext instance. The app ships as an installable module with its own DocTypes (for example an E-Invoice Log, E-Waybill Log, and GSTR Reconciliation document set), server-side logic wired through hooks.py doc events (on_submit, on_cancel, validate) so IRN and e-waybill actions fire deterministically from the Sales Invoice lifecycle rather than from ad-hoc button clicks. IRP and e-waybill calls run through whitelisted server methods (@frappe.whitelist()) against the government/GSP APIs, with request/response payloads, acknowledgement numbers, and signed QR strings persisted for audit. A print format renders the mandated QR code and IRN on the customer invoice. GSTIN validation runs both interactively (a client script on Customer/Supplier/Address) and in bulk, and a scheduler event (scheduler_events in hooks.py) pulls GSTR-2A/2B data on a cadence and stages it for matching. Role profiles and DocType permissions keep IRP credentials and cancellation rights scoped to your tax team.

Because this is built to order, nothing is a black box. We scope your exact turnover threshold, GSP/ASP choice, place-of-supply rules, ITC-matching tolerance, and reconciliation policy, then deliver source code tuned to that scope. Delivery is typically 2-4 weeks from confirmed scope. You get the app validated on a staging copy of your ERPNext, a UAT sign-off, a documented rollback plan, and a post-go-live support window — not a marketplace download you are left to configure alone. The app targets Frappe/ERPNext v15 and v16, and the full git repository is handed over to you at the end.

Who this is for

Accounts / Tax Manager

Owns GST filing at an Indian GST-registered business on ERPNext. Needs IRNs and e-waybills raised without manual portal work, and GSTR-2B reconciliation that protects ITC and closes each filing cycle on time.

Finance Controller / CFO

Accountable for audit-ready compliance and clean ITC. Wants every e-invoice, cancellation, and reconciliation decision logged inside ERPNext with role-scoped controls rather than spread across spreadsheets and the GST portal.

ERPNext System Administrator

Runs the Frappe bench and manages upgrades. Needs a properly packaged app with clean migrations, scheduler jobs, and permission profiles that survive v15-to-v16 upgrades and don't collide with existing customizations.

Logistics / Dispatch Lead

Cannot ship without a valid e-waybill. Needs Part-B updates, extensions, and cancellations handled directly from the delivery workflow, with e-waybill numbers exposed for the transport team.

How India GST Compliance & E-Invoice Suite Compares

Criterion	ECOSIRE	Custom Build	Competitor	ERPNext Native
Delivery model	Build-to-order, installed and supported for you in 2-4 weeks	In-house build; months of dev time and no external support	Instant install but generic; you configure and troubleshoot alone	Available immediately but only base GST tax scaffolding
E-invoice IRN	Automated IRP registration on submit, logged with QR on print format	Possible but you build every IRP call and edge case	Usually covered, but wired to its own assumptions	Not built in; needs the india_compliance app or custom work
E-waybill	Generation, Part-B updates, extension and cancel, all logged	Full transport-workflow build on your team	Basic generation; updates/extensions often thin	Not provided in core
GSTR-2A/2B reconciliation	Scheduled pull plus tolerance-based ITC matching to your policy	You design and maintain the whole matching engine	Generic matching, limited tolerance tuning	No reconciliation; done manually or in spreadsheets
Fit to your process	Scoped to your threshold, GSP, place-of-supply and ITC rules	Fully tailored, but you own every design decision	One-size-fits-all defaults	Generic; you adapt your process to the tool
Source code and handover	Full git repo handed over, yours to keep	You own it, and you carry all the maintenance	Often closed-source or license-locked	N/A — it's core, not a deliverable
Support and updates	Post-go-live window plus optional maintenance for API/law changes	Only what your team can staff	Vendor support varies; roadmap not yours to steer	Community/ERP vendor releases, no compliance guarantee
Version support	Targeted and validated on your ERPNext v15/v16 on staging	Depends on your team's testing discipline	Whatever versions the vendor chooses to track	Ships with the version you're running

Frequently Asked Questions about India GST Compliance & E-Invoice Suite

Is this an instant download from the Frappe marketplace?

No. It is build-to-order. ECOSIRE builds the app against your specific GST configuration — turnover threshold, GSP/ASP, place-of-supply and ITC-matching rules — then installs and supports it on your ERPNext instance. There is no instant download.

How long does delivery take?

Typically 2-4 weeks from confirmed scope. The timeline starts once we've agreed your GSP/ASP choice, reconciliation policy, and any customizations in a scoping session, and depends on the complexity of your existing ERPNext setup.

How does it handle e-invoice IRN generation?

A Sales Invoice `on_submit` doc event (registered in `hooks.py`) calls a whitelisted server method that submits to the NIC IRP via your GSP/ASP, then stores the returned IRN, acknowledgement number, and signed QR in an `E-Invoice Log` DocType. The QR and IRN print on the customer invoice, and duplicate-submit guards prevent double registration.

Which ERPNext versions are supported?

Frappe/ERPNext v15 and v16. The app is packaged as a standard Frappe app with clean migrations so it installs on your bench and survives upgrades. Tell us your exact version during scoping and we target it precisely.

What about ongoing support and government API or regulation changes?

Every build includes a post-go-live support window for defect fixes and filing-cycle questions. GST schemas, IRP endpoints, and thresholds change over time; changes beyond the support window, or new statutory requirements, are handled under a separate support/maintenance agreement so your compliance stays current.

How does purchase reconciliation and ITC matching work?

A scheduler job pulls GSTR-2A/2B data and stages it in a reconciliation DocType. The engine matches booked Purchase Invoices against portal data with configurable tolerance on GSTIN, invoice number, date, and value, then flags matched, mismatched, missing-in-books, and missing-in-portal lines for your team to action before claiming ITC.

Will it interfere with our existing ERPNext customizations?

We deliver as a separate Frappe app with its own DocTypes and hooks, validate it on a staging copy of your instance during UAT, and provide a tested rollback plan before production cutover — so it layers on top of your setup rather than overwriting it.
