Retailers who want to hand customers a prepaid balance quickly hit a wall in stock Odoo. Native Odoo has gift cards and some eWallet mechanics in Enterprise eCommerce, but there is no first-class, portal-visible "store wallet" a shopper can top up, spend partially at checkout, and watch as a running ledger. Refunds go back to the original payment method through account.move credit notes and payment reconciliation, which is slow and card-fee-heavy — there is no button to instantly return value as store credit the customer can respend the same day. That gap costs repeat sales and buries your support team in "where is my refund" tickets.

ECOSIRE builds a dedicated wallet layer on top of Odoo's own accounting and eCommerce plumbing. At the core is a store.wallet model (one balance per res.partner, company_id-scoped for multi-company) plus a store.wallet.transaction ledger where the running balance is a stored compute field driven by @api.depends over every credit and debit line, so the figure on screen and the figure in the database can never drift. Top-ups run through Odoo's existing payment.provider / payment.transaction flow (Stripe, PayPal, bank transfer — whatever you already accept); on a confirmed transaction a server action posts a top_up ledger row. Optionally each wallet is backed by a dedicated account.account liability so your accountant sees outstanding credit as a real balance-sheet number rather than a spreadsheet guess.

At checkout — both the website sale.order and the POS pos.order — we add a "Pay from wallet" option that debits the balance and can be combined with card or cash for partial payment, so a customer with 40 in credit can spend it against a 100 order and pay the rest normally. Refunds are the headline feature: from an order or a credit note, staff (or an automated rule) issue an instant refund credit that lands in the wallet in seconds instead of days. Cashback and loyalty rules are configurable records — percentage or fixed, per product category, per customer group, or per campaign window — evaluated by an @api.depends-aware engine and posted as cashback ledger rows on order confirmation. Every movement is exposed in the customer's /my portal via a QWeb-rendered statement, and the same balances are reachable over the XML-RPC / JSON-RPC API so a POS terminal, mobile app, or marketplace connector can read and debit the wallet programmatically.

Because this is build-to-order, nothing ships until we agree on scope. A short scoping call establishes your edition (Community vs Enterprise — it changes how we hook eCommerce and POS), your target versions (17.0 / 18.0 / 19.0), and the exact top-up, refund and cashback rules for your business. We then build the module against your data on a staging instance, secure it with ir.model.access.csv and record rules so customers only ever see their own wallet, run UAT with you, and deploy behind a rollback plan. Typical delivery is 2–4 weeks from confirmed scope, and you receive the full source and git repository at handover.
