Ecommerce integration services
Shipping and 3PL integration for your ecommerce store
Orders go to your shipping tool, carrier or fulfilment warehouse, and tracking and stock come back to the store.
The short answer
We connect your Cmsmart Ecommerce or WooCommerce store to shipping software, carrier label APIs or a 3PL warehouse, such as ShipStation, Shippo, EasyPost, ShipBob or ShipHero. Paid orders go out, and tracking and stock come back to the store. We assess the route first for free, then quote the build.
| Scope | Orders to a shipping tool, carrier or 3PL; tracking, labels and stock back to the store |
|---|---|
| What syncs | Paid orders out; tracking number and link, shipment status and warehouse stock back |
| Typical inputs | Shipping or 3PL account with API access, your service levels, example orders |
| Deliverables | Data map, integration on staging, tested shipments, monitoring, run book |
| How pricing works | Free assessment, then a quote per project paid by milestone. Carrier, tool and 3PL fees are paid to them. |
Data flow
How the data moves
The problem
What does re-keying shipments and tracking cost?
- Orders copied into a shipping tool or a 3PL portal by hand
- Tracking pasted back into orders one at a time
- Stock held by a 3PL that the store cannot see
- Labels printed from the wrong service level
- Personalised orders that need a file or note sent with them
What syncs
What moves, which way, and when
| Data | Direction | System of record | Trigger | Notes |
|---|---|---|---|---|
| Paid orders | Store to shipping tool or 3PL | WooCommerce | Webhook or schedule | Orders in Processing, with address and items |
| Labels and service level | Both ways | Shipping tool or carrier | On order | Rates and service chosen by your rules |
| Tracking number and URL | Shipping tool or 3PL to store | Shipping tool or 3PL | Webhook or polling | Added to the order and the customer email |
| Shipment status | To store | Carrier or 3PL | Webhook or polling | Shown in My Account |
| Inventory | 3PL to store | 3PL | Schedule | Only where a 3PL holds your stock |
Typical defaults. The final directions, triggers and frequency are set in the assessment.

-
Any other 3PL
A 3PL with an API, an EDI exchange or an SFTP file drop can be connected. The assessment states what each route supports.
Approach
Connector, integration platform or custom code
The free assessment compares the three on fit, cost driver and limits, and tells you which one we would pick and why.
-
A. Marketplace connector
A licence from the WooCommerce Marketplace or the system's own app store, configured for you.
Fits: Standard flows and a well-supported system.
Limits: Limited to what the connector exposes; fees are paid to its vendor.
-
B. Integration platform
A hosted integration platform that moves data between apps, for example Celigo, or Make for light flows.
Fits: Several systems, or upkeep by a non-developer team.
Limits: A monthly platform fee, and platform-specific logic.
-
C. Custom integration
WooCommerce REST API and webhooks connected to the other system's API, with a queue, retries and logs, built as custom development.
Fits: B2B prices, personalised files, multi-supplier routing or an unusual system.
Limits: We build and maintain it, so it is quoted per project.
Often a mix: a connector or platform for the standard flows, plus custom logic for B2B prices, personalised files or multi-supplier routing. Built as custom development.
The Cmsmart angle
What is core, and what is built for you
Cmsmart Ecommerce is built on WooCommerce. The designer side is part of the product. The bridge to your other systems is custom development.
Core Core in Cmsmart Ecommerce
- Each personalised order line carries its own design
- The designer exports a print-ready PDF for a design
- WooCommerce REST API and webhooks (WooCommerce core)
Custom Custom development
- The bridge that sends a file or an order to another system
- Field mapping, price-list logic and routing rules
- Queue, retries, logs and alerts
Scope
Included, not included, and extra
Included
- A data map of orders, labels, tracking, status and stock

What we need from you

- Admin or sandbox access to the other system, and an API user with only the rights needed
- A named owner on your side for each synced object (products, stock, prices, customers, orders)
- A staging copy of your store, or approval to create one
- Examples of real orders, including the awkward ones (partial shipments, refunds, custom items)
- Your volumes: orders per day, number of products and the busiest days
Process
How an integration project runs
Each phase is a milestone, approved and invoiced one at a time in your dashboard. The timeline is set in the assessment, because it depends on your systems and volumes.
- Free integration assessment. We review your systems, the owner of each field, your volumes and API access, and tell you what is feasible.
- Architecture and data map (milestone 1). A signed-off design that states what syncs, which way, how often and which system owns each field.
- Build in sprints on staging, using sandbox accounts of your systems.
- User acceptance testing with your own order, price and file scenarios.
- Go-live with a cut-over plan, a back-fill of open orders and monitoring switched on.
- Support. Tickets in your dashboard, health checks, and updates when either system changes its API.
Enterprise support tier
For integrations your operations depend on
Response targets, monitoring and review cadence are set in your agreement, not on this page.
- Monitoring of sync health and failed jobs, with a monthly sync report
- A named team that stays after launch
- A security review before go-live
- WooCommerce and connected-system upgrades tested on staging first

FAQ
Frequently asked questions
Which shipping tools and 3PLs can you connect?
ShipStation, Shippo, EasyPost, ShipBob, ShipHero, carrier label APIs from DHL, UPS or FedEx, or another 3PL by API, EDI or SFTP. We compare a ready-made plugin with custom code in the free assessment.
Can tracking come back to the order automatically?
Yes. Tracking number and link return to the WooCommerce order and the customer email, by webhook or polling, depending on what the tool or 3PL offers.
Can stock held by a 3PL show in the store?
Yes, where the 3PL exposes inventory through an API or a file. How often it refreshes is set in the assessment.
What about personalised products?
The order can carry the print-ready file of each line or a note. For print-on-demand suppliers, see the POD and fulfilment integration.
What if the shipping tool or 3PL is down?
Orders wait in a queue and are retried. A repeated failure raises an alert and the order shows its state in the admin.
How is the project priced?
There is no public price. After the free assessment you receive a quote, with the data map as milestone 1. Carrier and tool fees are paid to them.
