About this Product
India GSTR Filing & GSTR-2B Reconciliation is a build-to-order Odoo module that ECOSIRE designs, builds, installs and supports for your business — it is not an instant apps.odoo.com download. After purchase, our Odoo engineers scope your GST setup (GSTINs, HSN/SAC coverage, tax mappings, place-of-supply rules) and deliver a production-ready module tailored to your chart of accounts and filing cadence, typically within a one working week lead time.
The module lives natively inside Odoo Accounting. It reads your posted customer invoices and credit notes to generate a compliant GSTR-1 outward-supply return (B2B, B2CL, B2CS, credit/debit notes, HSN summary, and document series), and exports it in the government JSON schema for upload to the GST portal or your GSP/ASP. On the purchase side, it ingests the GSTR-2B statement downloaded from the portal and runs an intelligent reconciliation engine that matches each inward invoice line against your posted vendor bills — flagging mismatches, missing-in-books, missing-in-2B, and value/tax differences so you claim only eligible Input Tax Credit (ITC).
Under the hood we follow clean Odoo engineering: new business objects are defined as models.Model classes with proper fields and @api.depends compute methods for tax totals and match status; access is governed by ir.model.access.csv plus record rules so a consultant only sees the GSTINs they manage; screens are native list/form/search views (XML/OWL) with GSTIN-wise dashboards; and printable working papers ship as QWeb reports. Reconciliation can run on demand or via a scheduled automated action, and the whole feature set is reachable over Odoo's XML-RPC/JSON-RPC API for integration with a GSP portal or external bots.
We build for Community and Enterprise editions and support Odoo 17, 18 and 19, aligning the return logic to the l10n_in Indian localization already in your database. You get the module source, configuration on your instance, documentation, team training, and a defined support window — plus the confidence of a filing workflow that reconciles ITC before you file GSTR-3B, not after a mismatch notice arrives.
What you get
- Production-ready Odoo module source (custom addon with __manifest__.py, models, views, security, and QWeb reports) versioned for your Odoo 17/18/19 instance
- Installation and configuration on your Odoo instance, including GSTIN setup, tax-code mapping, and alignment with the l10n_in localization and your chart of accounts
- GSTR-1 JSON export mapping validated against a sample period from your live data
- GSTR-2B reconciliation ruleset tuned to your matching tolerances and vendor-master data
- ir.model.access.csv and record rules configured for your team's roles and multi-GSTIN structure
- Written user documentation plus an admin/technical guide covering the filing and reconciliation workflow
- Live training session for your accounting and tax team with a recording for future reference
- A defined post-go-live support and bug-fix window with a named point of contact at ECOSIRE
Who this is for
In-house Indian accountant / finance manager
Runs monthly and quarterly GST returns from within Odoo and needs GSTR-1 and GSTR-3B generated straight from posted invoices, without exporting to spreadsheets or a separate GST tool.
GST practitioner / tax consultant
Manages returns for multiple client GSTINs and needs record-rule-scoped access, fast GSTR-2B reconciliation, and printable working papers to justify every ITC claim before filing.
Controller / CFO of a multi-GSTIN group
Wants GSTIN-wise liability and ITC dashboards, period locking, and a controlled workflow so ITC is reconciled before GSTR-3B is filed and mismatch notices are avoided.
Odoo administrator / ERP owner
Needs a maintainable, upgrade-safe custom addon that respects Odoo access rules and integrates cleanly with the existing l10n_in localization and accounting configuration.

Frequently Asked Questions about India GSTR Filing & GSTR-2B Reconciliation
How long does it take to build and deliver this module after I purchase?
This is a build-to-order module, not an instant download. After purchase we scope your GST setup — GSTINs, tax mappings, HSN/SAC coverage, and filing cadence — then build, install and validate the module on your instance. Typical lead time is one working week depending on the number of GSTINs and how customised your chart of accounts and tax configuration are. You get a clear schedule during scoping.
What support and updates are included after go-live?
Delivery includes a defined post-go-live support and bug-fix window with a named ECOSIRE contact. During that window we fix defects, adjust reconciliation rules, and help your team. We also maintain the module against Odoo point releases within your major version and can update the GSTR JSON schema mapping if the GST portal changes format. Extended support and version-upgrade retainers are available separately.
Does it work on Odoo Community or only Enterprise, and which versions are supported?
We build for both Odoo Community and Enterprise editions and support Odoo 17, 18 and 19. The module aligns with the l10n_in Indian localization already in your database. During scoping we confirm your exact edition and version so the delivered addon is upgrade-safe on your instance.
Does it file returns automatically on the GST portal for me?
The module generates GSTR-1 in the government JSON schema and computes GSTR-3B inside Odoo, and it reconciles GSTR-2B against your vendor bills. Final submission is done by uploading the JSON to the GST portal or through your GSP/ASP — we can also wire the module's XML-RPC/JSON-RPC endpoints to an approved GSP integration if you use one. This keeps you in control of what is actually filed.
How does GSTR-2B reconciliation match against my vendor bills?
You download the GSTR-2B statement from the portal and import the JSON into Odoo. The reconciliation engine matches each inward line against your posted vendor bills on counterparty GSTIN, invoice number, date, and tax values within configurable tolerances, then flags each bill as matched, value/tax difference, missing-in-2B, or missing-in-books. You can drill from any line to the underlying bill, so you claim only eligible ITC before filing GSTR-3B.
Will it fit our existing accounting setup and multi-GSTIN structure?
Yes. We configure it around your chart of accounts, tax codes, and the l10n_in localization, and use ir.model.access.csv plus record rules so each accountant or consultant sees only the GSTINs they manage. GSTIN-wise dashboards give controllers a consolidated view while keeping data access properly scoped.
