CS-Cart Integration Services
Connect CS-Cart and CS-Cart Multi-Vendor to your ERP, inventory system, couriers and payment gateways, with sync that recovers when the other side is down.
Plan Your IntegrationConnect CS-Cart to the systems your business runs on
A CS-Cart store rarely works alone. Stock lives in an inventory system, invoices in an ERP, shipments with couriers, and payments with a gateway. When those systems don't talk to the store, someone re-types orders, stock goes out of date, and customers buy products that are no longer on the shelf.
We connect CS-Cart and CS-Cart Multi-Vendor to those systems. Each integration is built as a CS-Cart addon on the official hook system, so it survives upgrades, can be switched off from the add-on manager, and keeps the store's core files untouched. If you need a store feature rather than a connection to another system, see our CS-Cart addon development service.
What we integrate
ERP systems
Orders and customers sent from CS-Cart to the ERP, and invoices or status updates read back. Where the ERP has no API, the exchange runs through a middleware database or file transfer.
How the SAP integration works →Inventory systems
Stock, products and prices kept in step between CS-Cart and the inventory system, and orders pushed across as they are placed, so the store stops overselling.
Zoho Inventory integration case study →Courier integrations
Direct connections to courier APIs for live rates, AWB numbers, labels, pickups, tracking and COD remittance: Ekart, DTDC, Safexpress, XpressBees and Shri Maruti.
Multi-carrier courier integrations →Shipping aggregators
One connection to an aggregator instead of many couriers: carrier rates and choice, AWB and labels, returns, and tracking updates received by webhook.
ClickPost integration for CS-Cart →Payment gateways
Gateway callbacks, payment status sync and refunds wired into the CS-Cart order flow, including split payments where part is paid online and the rest on delivery.
Partial COD with Juspay →How CS-Cart integrations work
Every integration answers the same questions: which system owns each piece of data, how changes travel, and what happens when one side is unavailable. We choose the transport per system rather than forcing one pattern on all of them:
- APIs. Outbound calls from the addon to the other system's REST API, and the CS-Cart REST API for systems that need to read or update the store.
- Webhooks. An endpoint inside the addon receives events such as shipment status changes and updates the matching order, after checking the request is genuine.
- Middleware and files. When a system cannot call or be called directly, data moves through a shared middleware database or files on FTP. Our SAP integration sends orders and customers through a middleware database and reads SAP invoices back from FTP.
- Scheduled jobs and queues. Bulk work such as stock and price sync runs on cron in batches. Real-time events, a placed order or a status change, are picked up from hooks like
place_orderandchange_order_statusand queued, so a slow remote system never slows the checkout.
Around the transport sit the parts that make an integration dependable: a mapping table between CS-Cart IDs and the other system's IDs, retries with a limit, a log of every exchange that the store admin can read, and protection against processing the same event twice. The Zoho Inventory sync was built this way to end manual stock updates and overselling for a B2B food distributor.
Who owns which data
Before any code is written, we agree one owner for every field. Typically the ERP or inventory system owns stock, cost and prices; CS-Cart owns the order until it is placed; the courier owns tracking status; the gateway owns payment status. Two-way sync without that rule ends with systems overwriting each other's changes.
Where both sides can edit the same record, we compare timestamps, apply a defined winner and log every overwrite so the admin can see what changed and why. On CS-Cart Multi-Vendor the decision can differ per vendor: one vendor manages stock in the marketplace while another syncs from their own system, keyed by the vendor's company_id.
How an integration project runs
-
1.
Access and API review: We review the other system's API, file formats or database access, and arrange sandbox or test credentials.
-
2.
Data mapping: A written map of which fields move in which direction, which system owns them, and how often they sync.
-
3.
Build on staging: The addon is built and tested on a staging copy of your store against the other system's test environment.
-
4.
Go-live and reconciliation: We switch on the live connection and compare records on both sides until the data matches.
-
5.
Support: 30 days of free bug-fixing and support after addon delivery.

Frequently Asked Questions
Which systems can you integrate with CS-Cart?
Any system that offers an API, webhooks, file exports or database access. We have built integrations with SAP, Zoho Inventory, ClickPost, Juspay and Indian couriers including Ekart, DTDC, Safexpress, XpressBees and Shri Maruti.
Our system has no API. Can it still be integrated?
Often, yes. Data can move through a shared middleware database or through files exchanged over FTP, which is how our SAP integration sends orders out and reads invoices back.
Is the sync real-time or scheduled?
Both, depending on the data. Orders and status changes are sent as they happen, triggered from CS-Cart hooks. Large jobs such as full stock or price updates run on a schedule in batches so they do not slow the store.
What happens if the other system is down?
The store keeps taking orders. Outgoing data waits in a queue and is retried, every exchange is logged for the admin, and nothing is sent twice when the other system comes back.
How much does a CS-Cart integration cost?
Integrations are built as addons, which start from $1,500, scoped per store. The final price depends on how many data types sync, in which directions, and how the other system exposes its data.
Do integrations work with CS-Cart Multi-Vendor?
Yes. On Multi-Vendor we decide with you whether data maps per vendor or for the whole marketplace, and handle parent and child orders so each vendor order reaches the other system correctly.
