Integrations
CRM to ERP, storefront to fulfilment, payments to accounting, a legacy database to a new app: any two systems that need to talk, connected through the right method for the job and engineered to fail loudly, retry safely and reconcile automatically.

Businesses that run on what we built
The general case
API integration connects two or more software systems so data and events flow between them automatically: orders from a storefront into an ERP, leads from a website into a CRM, payments into accounting, stock levels to a marketplace. Done well it removes re-keying and delay. Done badly it silently drops the one record in a thousand that mattered.
If your business runs on Odoo, the Odoo Integration page covers that specifically. This page is the general case: any systems, any direction, including legacy and undocumented ones, with Odoo as one participant among several when it's involved.
Integration types
The method is a design decision, not a default. We choose per integration.
| Type | How it works | When it fits | Watch out for |
|---|---|---|---|
| Point-to-point API | One system calls the other's API directly | Two systems, clear ownership, moderate volume | Becomes a tangle past three or four systems |
| Webhook / event-driven | The source pushes events as they happen | Near-real-time needs: payments, orders, status changes | Duplicate deliveries, signature validation, retries |
| Middleware / iPaaS | A hub (Zapier, custom service, queue) routes between systems | Many systems, transformations, non-developers maintaining flows | Vendor limits, cost at volume, debugging across hops |
| Batch / ETL | Scheduled extraction, transformation and load | Reporting, reconciliation, systems with no events | Window overlap, partial failures, stale data between runs |
Most real integrations combine two: webhooks for the live path and a nightly batch reconciliation to catch what the live path missed.
What we connect
Categories from production work. Named systems are ones we have actually connected.
Stripe, Razorpay (incl. subscriptions), Cashfree, Paytm POS terminals: into orders, invoices and accounting.
Zoho CRM/Books, Monday.com, Calendly: leads, contacts, deals and events both ways.
Shiprocket rates and labels, barcode/RFID scanners, direct printing.
Swedbank API for statements and payments. Reconciliation into the ERP.
MSG91 and Twilio SMS/OTP, Firebase push, Outlook IMAP, SMTP.
Zapier flows and custom middleware where no-code is the right tool.
Odoo as source of truth for products, orders, customers and stock: exposed through REST and GraphQL.
Databases, file drops, SOAP, undocumented internal apps: wrapped in an API and connected safely.
Architecture
Past two or three systems, point-to-point links multiply. An integration layer keeps rules, retries and logs in one place.
Storefront + apps
Web, mobile, marketplaces
Payments + logistics
Gateways, terminals, carriers
CRM + SaaS + legacy
CRM, calendars, automation, old databases
Integration layer
API gateway · webhooks · queues · transformations · retries · idempotency · logging · monitoring
Systems of record
ERP (Odoo), custom services, finance: business rules stay where they live
Reconciliation
Scheduled comparison across systems, drift found and corrected
Reliability
Transient failures are retried, not lost.
A duplicated webhook creates one order, not two.
A sale or an import doesn't take the ERP down.
Every message logged with status. Failures raise alerts.
Nightly comparison of both sides catches silent drift.
API contracts documented and versioned so an upgrade on one side isn't an outage on the other.
Evidence
Payments, banking, SaaS tools, mobile APIs and partner automation: running for years.
Jewellery retail & manufacturing
Multi-store fine jewellery retail and manufacturing on Odoo Enterprise: daily metal rates, RFID-tagged serialized stock, gold saving schemes with recurring payments, and a customer mobile app synced over GraphQL.
Cloud managed services
Accounting, HR and payroll, projects and timesheets, subscriptions, helpdesk and CRM on Odoo 18 Enterprise, with custom modules migrated from earlier versions and financial reporting built for a recurring-services business.
ERP consulting (Odoo partner)
Heliconia developers working as an extension of another Odoo partner’s engineering department: multiple client migrations from Odoo 17 to 18 Enterprise, custom module upgrades, Odoo.sh operations, and Monday.com, Calendly and Zapier integrations.
SaaS: digital business cards
Digital profile and contact-sharing platform where Odoo runs subscriptions, orders and the store behind a web frontend and a Flutter mobile app, with Stripe recurring payments, Google integrations and vCard export.

Both, chosen per case. Existing connectors and platforms like Zapier when they fit and someone non-technical will maintain the flow. Custom integration services when volume, reliability, transformation or a system without a connector demands it.
Yes. We reverse-engineer the data model, wrap the system in a small API or scheduled extraction, and connect through that layer, so the legacy system is never touched by the other side directly.
Odoo Integration is the Odoo-specific service: connecting Odoo to everything around it, with Odoo as the system of record. This page is the general case: any systems, Odoo included as one participant. If Odoo is at the centre, start there.
Retries with backoff, idempotent writes, dead-letter queues, logging with full payloads, alerts, and scheduled reconciliation so anything that slipped through is found.
Near-real-time through webhooks and queues. Genuinely real-time features (live chat, presence) run on a dedicated Socket.IO service.
Yes: monitoring and maintenance as the systems on both sides change, under an ongoing engagement.
