E-Commerce Integration
Shopify + Odoo Integration
Run Shopify for storefront + Odoo for operations and finance — with native bidirectional sync that doesn't break on every Shopify Plus version bump. Products, inventory, orders, fulfilments, customers, refunds, and accounting entries flow in real time, no manual exports, no reconciliation Excel files.

What it is
Bidirectional real-time integration between your Shopify storefront(s) and your Odoo ERP. The integration handles: product catalog sync (Odoo as master, Shopify as channel — or the reverse if you prefer); inventory level sync (Odoo's multi-warehouse stock pushed to Shopify per-location); order capture (Shopify orders create Odoo sales orders with payment, customer, and shipping data); customer sync (B2C customers come down; B2B accounts can be Odoo-master); fulfilment flow (Odoo picks/packs/ships, status pushed to Shopify, tracking emailed to customer); refunds and returns (Shopify refunds create Odoo credit notes; returns flow back to inventory); accounting entries (sales, taxes, shipping, refunds posted to Odoo accounting automatically); Shopify Payments / Shop Pay / payment gateway reconciliation. Built on Odoo's official Shopify connector with TechUltra-specific extensions for the edge cases that always surface in production.
Why it matters
Shopify-Odoo integrations are deceptively easy to build at the demo level and notoriously hard to maintain in production. Standard pitfalls: Shopify API rate limits during high-volume sales; partial-refund edge cases that mis-post to the wrong GL account; multi-currency Shopify stores creating FX gain/loss complications; gift cards that confuse the accounting flow; B2B Shopify Plus orders that need different pricing and payment terms; Shopify's frequent API deprecations breaking your sync silently. A production-grade integration is engineering work, not a connector install. TechUltra builds it once properly, then maintains it through Shopify's version bumps.
Features
-
Real-time bidirectional sync
Webhooks from Shopify trigger immediate Odoo updates; Odoo changes (inventory, products) push to Shopify within seconds. No batch jobs, no overnight delays.
-
Multi-store support
Businesses running multiple Shopify stores (regional, language-specific, brand-specific) handled in one Odoo instance. Each store is a separate sales channel with appropriate inventory allocation and accounting entity.
-
Multi-currency + FX gain/loss
Shopify stores in different currencies handled with appropriate FX rate capture at order time. FX gain/loss accounting recorded on currency-mismatch transactions.
-
Inventory allocation per store / location
Odoo's multi-warehouse inventory mapped to Shopify locations. Per-store inventory rules (e.g. EU warehouse ships EU store, US warehouse ships US store) configurable.
-
Returns + refunds handled cleanly
Partial returns, full returns, exchanges, gift-card refunds, store-credit refunds — all flow into Odoo with appropriate GL postings and inventory updates. Edge cases that break naive integrations.
-
Shopify Plus B2B support
B2B accounts, customer-specific pricing, payment terms (net 30, net 60), purchase order requirements, and B2B-only product catalogs handled. Shopify Plus advanced features supported.
-
Shopify Payments + gateway reconciliation
Shopify Payments fees, payout batches, chargebacks, and other gateway artefacts reconcile to Odoo bank accounts. Multi-gateway (Shopify Payments + Stripe + PayPal) supported.
-
Tax automation
Avalara, TaxJar, or Shopify's native tax engine reconciled with Odoo's tax codes. USA multi-state nexus, EU VAT including OSS, UK MTD VAT all supported.
-
Order-state machine
Shopify order states (paid, fulfilled, partially fulfilled, refunded, cancelled) mapped to Odoo states with consistent business logic. Edge transitions (e.g. partial fulfilment then partial refund then exchange) handled predictably.
-
Resilient to Shopify API changes
Built against Shopify's GraphQL Admin API with version pinning + automated regression testing. Shopify's quarterly API deprecations don't break production sync.
How it works
-
Discovery + audit
Audit your current Shopify setup (stores, apps, payment gateways, tax setup, B2B if any) and Odoo state. Identify sync direction (product master in Odoo or Shopify), edge cases, multi-store complexity. Output: written integration spec.
-
Sandbox build
Build the integration in Odoo sandbox connected to a Shopify development store. Test core flows: product sync, order capture, fulfilment, refund, return. Iterate on edge cases.
-
UAT with sample orders
Run sample orders end-to-end through the sandbox. Validate accounting postings, inventory updates, customer records. Sign-off from finance + operations.
-
Production cutover
Schedule cutover during a low-traffic window. Switch Shopify webhooks to production Odoo. Initial sync of existing customer + product data. Monitor first 48 hours.
-
Stabilisation + tuning
First 30 days with the integration team on-call. Tune rate limits, batch sizes, error handling based on real production volume. Adjust for Black Friday / peak-traffic scenarios if applicable.
-
Ongoing maintenance
Shopify pushes quarterly API updates; we apply the integration updates within the Shopify-supported window. Bundled into ongoing support retainer.
Deployment timeline
Single-store Shopify integration: 3–5 weeks fixed-price. Multi-store (2–5 stores, single Odoo): 5–8 weeks. Shopify Plus with B2B + advanced features: 6–10 weeks. Migration from an existing third-party connector (Shopify ↔ Odoo via a paid app): often faster (2–4 weeks) since the data model is established.
Best for
Businesses running Shopify storefront(s) with Odoo as the ERP (or planning that combination). Particularly: multi-store operations where store-by-store reconciliation in spreadsheets is eating time; growing brands at 100+ orders/day where order processing manual entry is no longer viable; multi-currency businesses where FX gain/loss accounting matters; Shopify Plus customers with B2B requirements; businesses considering moving off Odoo eCommerce to Shopify but wanting to keep Odoo's ERP backbone. Not yet a fit for very small Shopify stores (under 20 orders/day) — Shopify alone with a CSV-to-accounting tool is often sufficient.
Frequently asked questions
-
Why not just use a Shopify App Store connector?
App Store connectors work for simple flows — single store, basic order capture, no edge cases. For real production use (multi-store, multi-currency, B2B, returns and exchanges, complex tax, Shopify Plus features) most connectors hit limits or break on edge cases. We build production-grade integrations specifically because the connectors don't cover real-world complexity. That said, for simple use cases an App Store connector can be the right answer — we'll say so honestly during discovery.
-
Can we have Odoo as master vs Shopify as master?
Either direction. Most common: Odoo as master for products + inventory + pricing, Shopify as the storefront channel. Less common but supported: Shopify as master with Odoo as the back-end fulfilment + accounting system. Direction set during discovery based on where your team naturally works.
-
What about Shopify Plus B2B?
Yes — supported. B2B accounts, customer-specific pricing, payment terms, purchase order workflow, B2B-only catalogs, draft orders for negotiated deals. Shopify Plus B2B is closer to traditional ERP-CRM functionality than standard Shopify, and the integration with Odoo reflects that.
-
How do refunds and returns work?
Shopify refunds create Odoo credit notes with appropriate GL postings (revenue reversal, COGS reversal, return-to-inventory). Partial refunds, exchanges, gift-card refunds handled per their specific accounting requirements. This is one of the areas where naive integrations break — we test these edge cases thoroughly in UAT.
-
Does the integration handle Shopify Payments?
Yes — Shopify Payments payout batches reconcile to Odoo bank accounts automatically. Shopify Payments fees, chargebacks, disputed transactions all flow to appropriate GL accounts. Multi-gateway setups (Shopify Payments + Stripe + PayPal + Klarna etc.) all supported.
-
What's the integration cost?
Single-store: USD 8,000–15,000 fixed-price implementation. Multi-store (2–5 stores): USD 15,000–35,000. Shopify Plus with B2B: USD 18,000–45,000. Ongoing maintenance bundled into the support retainer ([/solutions/odoo-support-sla](/solutions/odoo-support-sla)) — typical USD 200–600/month of retainer time dedicated to Shopify integration upkeep.
-
Can we migrate from an existing Shopify-Odoo connector?
Yes — common. Many customers start with a Shopify App Store connector, hit its limits, and move to a TechUltra-built integration. Existing data structure carries over (customers, products, historical orders); we replace the sync layer with a more robust implementation. Migration typically 2–4 weeks.
-
How do you handle Shopify's frequent API updates?
Integration is built against Shopify's GraphQL Admin API with version pinning + automated regression tests. Each Shopify API release (quarterly) triggers a sync update within Shopify's supported window. Customers don't see breakage from API changes.
-
Will it work with Odoo eCommerce too?
Yes — common pattern is Odoo eCommerce for B2B + Shopify for B2C, both syncing to the same Odoo backend. Or Odoo eCommerce as a wholesale portal while Shopify handles retail. Both storefronts share Odoo's product, inventory, customer, and accounting data.
-
Does it handle EU VAT OSS for cross-border sales?
Yes. EU OSS (One Stop Shop) registration captures, VAT rate-by-destination, OSS quarterly return data — all handled. UK post-Brexit handling for EU customers shipping into UK and vice versa.
-
What if we're on Odoo Online (not Odoo.sh)?
Odoo Online supports official Shopify connector but doesn't allow custom code, so the integration is limited to what the connector covers. Our extensions need Odoo.sh or self-hosted Enterprise. If you're on Odoo Online and need the full integration, the path is migrating to Odoo.sh (typically a small project) as part of the integration.
-
What's the first step?
30-minute scoping call. Bring: Shopify plan (Basic / Shopify / Advanced / Plus), store count, monthly order volume, current Odoo state, complexity factors (multi-currency, B2B, custom checkout, etc.). We'll outline the right next step and propose discovery week if appropriate.
