Most cart abandonment on an Odoo website happens in the last two screens: the /shop/cart review and the /shop/payment step. Shoppers hesitate because they can't see at a glance that the store is secure, which cards you accept, what shipping will cost, or whether a coupon they were promised actually applies. Odoo's native eCommerce (the website_sale module) renders a clean but deliberately minimal checkout — it shows acquirer logos only after a payment method is selected, has no trust-seal band, no accepted-card row above the fold, no inline shipping estimator on the cart, and no urgency signalling tied to stock.quant. On Community there is even less: several conversion-oriented widgets and some acquirer integrations are Enterprise-only. Merchants end up either living with the leak or bolting on generic apps that don't respect the Odoo theme or the pricelist/tax engine.

We build a cohesive conversion kit as a proper Odoo addon rather than a pile of theme snippets. The module ships its own __manifest__.py depending on website_sale (and sale, stock, payment), a set of QWeb templates that extend the checkout views via <xpath> inheritance so your existing theme and any other installed apps keep working, and OWL components for the interactive pieces. The accepted-payment badge row is data-driven: instead of hardcoded images it reads the enabled payment.provider/payment.method records for the current company and website, so the badges always match what will actually work at payment time. The SSL/secure-checkout seals and the express-wallet buttons (Apple Pay / Google Pay / PayPal express, where your acquirer supports them) are placed through configurable positions rather than theme hacks, so upgrades don't wipe them out.

Under the hood the interactive widgets talk to the server over Odoo's JSON-RPC controllers. The inline shipping estimator calls a controller that runs your real delivery.carrier rating logic against a posted country/zip and returns a formatted amount honouring the customer's pricelist and fiscal position — not a made-up flat rate. The coupon field validates against sale.coupon/loyalty.program and shows the recomputed order total in place, so the shopper sees the discount before committing. Low-stock and urgency nudges are computed server-side from stock.quant available quantities on a @api.depends-driven compute field, with a per-product threshold configurable in Settings, so you never display a false "Only 2 left" that contradicts inventory. Everything is gated by ir.model.access.csv and, where a config model is involved, record rules, and admin-facing settings live in a res.config.settings panel so non-developers can tune thresholds, toggle each element, and pick placements without touching code.

Because this is build-to-order, nothing is a generic download. After a short scoping call we confirm your Odoo version (17.0, 18.0, or 19.0), Community vs Enterprise, your active acquirers and carriers, and your theme. We then build the module against a copy of your setup, deliver it on a staging environment for UAT, and only promote to production once you sign off. Typical delivery is one working week from confirmed scope, and you receive the full source, a Git repository, and a post-go-live support window.
