We have built more than 100 Shopify apps. Twelve are still ours.
The rest were sold, or handed to the companies that commissioned them. Private apps, public App Store products, backend automation, and the integrations that connect Shopify to whatever else your business runs on.
Five kinds of Shopify build. We do all five.
Most Shopify app shops cannot do this part.
The app store is full of storefront widgets. The work that actually gets stuck is connecting Shopify to the systems a real business runs on, and that needs people who understand both sides. Devsinc runs a Salesforce practice alongside the Shopify practice, and has delivered ERP and logistics integrations across both. Same engineers, same building.
Salesforce and Shopify
Customer, order, and product sync between Shopify and Sales, Service, or Commerce Cloud, with identity resolution actually thought through.
Our Salesforce practice →ERP
Order, inventory, pricing, and financial sync across SAP, Microsoft Dynamics, Odoo, Sage, Candela, Orion, and Retail Pro.
Logistics and fulfilment
Carrier rate logic, label generation, tracking webhooks, multi-warehouse allocation, and cash-on-delivery reconciliation.
Payments
Multi-gateway orchestration, which is a whole product in its own right. UnumPay is the proof.
See UnumPay →POS and in-store
Unified inventory and customer records across online and physical retail, so one stock position serves both.
See Retail POS →A multi-country retailer selling on Shopify while running customer relationships in Salesforce, with fulfilment split across warehouses in several markets.
Shopify, Salesforce CRM, the ERP holding stock and pricing, and the warehouse and carrier systems in each country.
A Salesforce and Shopify integration with identity resolution across both records, plus omnichannel fulfilment routing that allocates each order to the right market and warehouse.
One customer record across both systems, and orders allocated to the right warehouse on the day they are placed rather than the day after.
ERPs we have genuinely integrated with Shopify: SAP, Microsoft Dynamics, Odoo, Sage, Candela, Orion, and Retail Pro. If yours is not on that list we will tell you what the integration surface looks like before quoting rather than after.
Private or public? It shapes everything.
You need a private app when
The problem is specific to your business, no public app fits without compromise, the logic touches internal systems, or the data cannot leave your control.
You need a public app when
The problem is shared by other merchants and you want to sell the solution. Multi-tenancy, billing, support, and App Store review all come with it.
Some apps were built to be sold.
Of the hundred-plus apps we have built, most are no longer ours. Some were commissioned and handed over, some were sold as products. If you have an internal tool that other merchants would pay for, or you want to build an App Store product as an asset rather than a feature, that is a path we have taken repeatedly and can take with you.

Each of these came out of a real merchant problem and earned its place on the App Store. Checkout, payments, returns, tracking, content, and logistics.

Tell us what you need built.
Send us the workflow, the systems it has to touch, and what it needs to do. You get an engineering assessment and a scoped proposal, not a discovery call that turns into a sales sequence.
- Read by an engineer who has shipped App Store products
- We will say if a public app already solves it and you do not need us
- Fixed-scope proposal, and the app is yours
