We built a backend and API layer for a growing commerce business. Orders, inventory, payments, fulfilment and customer updates now move reliably between the tools the company already used.
Industry: Retail & E-commerceService: SaaS & SoftwareUpdated
Overview
The challenge
The retailer used separate tools for e-commerce, inventory, payments, fulfilment and customer messaging. Each tool worked on its own, but the connections between them broke easily.
As order volumes grew, the company needed a backend that kept data in sync and gave every team the same view of what was happening.
Stock updates didn't always reach every sales channel in time.
Each failed integration created manual clean-up work for the operations team.
It was difficult to find where an order or payment update had failed.
The solution
We created a shared backend model for orders, customers, products, inventory and payments.
APIs and integration services keep the e-commerce, payment, inventory and fulfilment tools in sync.
Monitoring and automatic retries make integration problems visible and recoverable.
Before and after
Before
Point-to-point
Every connection had its own logic.
After
Central API layer
All systems connect through one consistent backend.
Before
Found by accident
Problems came to light only when customers or staff noticed them.
After
Tracked and retried
Integration problems are logged and can be recovered.
Before
Different views
Systems could show different order or stock positions.
After
Shared logic
Common business rules keep data consistent across systems.
Key features
A single backend handles data exchange between the commerce systems.
Business impact
Simpler integrations
Failed updates are tracked and retried instead of disappearing without a trace.

Fewer Manual Corrections
Orders and updates now pass through one dependable flow instead of fragile point-to-point links.

Faster Issue Resolution
Teams can see failed integrations and their retry status as they happen.

Easier Expansion
New systems connect to a reusable backend layer instead of needing a custom link each time.

Faster delivery
With these parts already built and tested, the team spent less time on setup and more on this retailer's integrations, and launched sooner.
Our tested authentication module gives each team role-based access to the orders and actions it needs.
The reusable API layer became the central hub that the e-commerce, payment, inventory and fulfilment tools connect through.
Existing monitoring and retry logic logs every failed update and tries it again automatically.
Status components show teams which integrations are healthy and which updates are waiting to retry.
Trust and control
People only see the information and actions their role needs.
ACCESS CONTROLLEDKey records and workflow updates stay linked in one place instead of being scattered across tools.
CONNECTEDMonitoring, retries and clear error handling keep the platform dependable.
RELIABLEThe client owns the custom product, workflows, integrations and source code built for the project.
100% OWNEDThe retailer ran separate tools for e-commerce, inventory, payments, fulfilment and customer messaging, joined by fragile point-to-point links. Stock updates didn't always reach every channel in time, failed syncs created manual work, and as order volumes grew nobody could easily trace where an order or payment update had failed.
The hub gives orders, customers, products, inventory and payments one shared data model, and every tool connects through a central API layer instead of its own custom link. Shared business rules keep data consistent, while monitoring logs failed updates and retries them automatically rather than letting them disappear.
New channels and tools connect through the same API foundation and data model, so the team reuses the existing backend instead of building a custom connection each time. Role-based access, monitoring and retry handling are already in place, so each new integration gets the same tracking and error recovery.
If stock, orders and payments drift out of sync between systems, we can build one backend that connects them, retries failures and shows your team what went wrong.
