sync_status: connected

Your systems weren't built to talk to each other. We fix that.

ERP, CRM, e-commerce, accounting, custom apps — we connect what you already run into one working system, so data moves on its own instead of through spreadsheets and copy-paste.

Integration work, by what you're connecting

Every stack is a different mix of old and new. Pick where the friction is and see how we approach it.

API Integration

We build and connect REST, SOAP and webhook-based APIs so your applications exchange data directly, without a person in the middle.

  • Custom API development for internal or partner-facing use
  • Third-party API connections — payments, maps, SMS, KYC
  • Authentication, rate-limiting and error-handling built in

ERP & CRM Sync

Keep customer, order and inventory data consistent across your ERP, CRM and storefront, instead of three different versions of the truth.

  • Two-way sync between SAP, Zoho, Tally and your CRM
  • Inventory and order sync with your e-commerce storefront
  • Conflict rules so both systems agree on which record wins

Legacy System Bridging

Old software running the business doesn't have to be replaced to be connected. We wrap it with a modern interface it can talk through.

  • Adapter layers for desktop, on-premise or file-based systems
  • Scheduled or event-based data pulls where a live API isn't possible
  • No disruption to the legacy system's day-to-day operation

Data Migration

Moving to a new platform without moving your history is not really moving. We map, clean and transfer records so nothing gets left behind.

  • Field-by-field mapping between old and new schemas
  • De-duplication and data cleanup before go-live
  • Parallel-run validation so nothing is missed at cutover

Workflow Automation

Once systems are connected, the handoffs between them can run themselves — approvals, notifications, invoice generation, status updates.

  • Trigger-based automation across connected systems
  • Automated alerts, approvals and document generation
  • Full audit trail of every automated action taken

How an integration project runs

Most projects land in four to eight weeks depending on how many systems are involved.

1

Systems Audit

Map every system, data source and hand-off currently in use.

2

Integration Design

Decide what connects directly, what routes through middleware.

3

Build & Connect

Develop the APIs, adapters and sync logic between systems.

4

Test in Parallel

Run alongside existing workflows until data matches exactly.

5

Go Live & Support

Cut over fully, with monitoring and support on the connections.

What teams get back once systems are connected

The point of integration isn't the connection itself — it's what stops happening manually.

Zero double entry Data entered once, in one system, reaches every other system it needs to.
Same-day visibility Sales, inventory and finance teams see the same numbers, updated live.
Fewer reconciliation hours Month-end no longer means manually matching records across systems.

System Integration — FAQ

Click a question to expand the answer.

No. Most integrations connect systems as they are. Replacement is only suggested when a system has no usable API, database access or export option at all.
We define a conflict rule upfront — usually one system is marked the "source of truth" for a given field, so there's never ambiguity about which value wins during a sync.
A single API connection can take one to two weeks. A multi-system project — ERP, CRM and a storefront together — usually runs four to eight weeks, including parallel testing.
Integrations are built with retry logic and queuing, so data waits and resends once the system is back rather than getting lost mid-sync.
Yes — every integration includes a support window post-launch, and ongoing monitoring can continue on retainer if a system needs active upkeep.
