Indian merchants running Odoo eCommerce, invoicing or a customer portal quickly hit a wall: Odoo core ships payment acquirers for Stripe, PayPal, Razorpay, Mollie and a handful of others, but there is no Cashfree provider out of the box. If Cashfree is your settlement and payout rail, you are stuck either pushing customers to a hosted Cashfree link outside Odoo (breaking the automatic invoice-and-order reconciliation Odoo is built for) or hand-patching the payment module — which the next odoo/enterprise upgrade will silently overwrite. Neither path gives you signature-verified webhooks, INR-correct amounts, or a payment transaction that reliably confirms the sale order.

ECOSIRE builds a proper Cashfree payment provider as a self-contained module that plugs into Odoo's native payment framework. We add a new payment.provider record with code = 'cashfree', extend payment.transaction for the create-order and verify handshake, and register both a seamless (JS/Drop-in) and a server-to-server redirect checkout flow so you can pick the UX that fits your storefront. The module declares its __manifest__.py with a clean dependency on payment (and website_sale where you sell online), ships its provider form view and QWeb payment-form template in XML/OWL, and locks everything down with ir.model.access.csv plus record rules so only accounting and system users touch credentials. Sandbox and production app_id/secret_key live in the provider record with the state toggle, exactly like every core acquirer — no hardcoded keys.

Technically, the checkout works the way Cashfree's PG API expects. On payment, Odoo calls orders to create a Cashfree order for the transaction reference and amount in INR, then hands the payment_session_id to the Cashfree JS SDK (seamless) or redirects to the hosted page. The return route and, critically, the asynchronous webhook are both handled: we verify the Cashfree webhook using the HMAC-SHA256 signature (x-webhook-signature over the raw body + timestamp) computed with your secret, in constant time, before we ever mark a transaction done. That means a spoofed callback cannot confirm an unpaid order. UPI, cards, netbanking and wallets are all surfaced as available methods; refunds and Cashfree instant refunds are wired to Odoo's refund flow so a credit note or a portal-initiated refund calls the Cashfree refunds endpoint and reconciles the returned status back onto the transaction.

Because this is honest build-to-order work and not an app-store download, we build against your exact Odoo version (17.0, 18.0 or 19.0) and edition (Community or Enterprise — the payment framework differs subtly between them and between versions, which is precisely why a generic listing breaks). You get the module tested end-to-end in Cashfree sandbox on a staging copy of your database before anything touches production. Everything is exposed through Odoo's ORM and the standard XML-RPC/JSON-RPC API, so headless storefronts and external order sources can trigger and read Cashfree transactions the same way they read any Odoo payment.

Delivery is typically one working week from confirmed scope. It starts with a short scoping call to pin down your Odoo version and edition, whether you need seamless, redirect or both, which payment methods to enable, your refund and payout requirements, and your sandbox credentials. From there we build, run UAT on staging, then install and go live on your production instance with a documented rollback and a post-go-live support window.
