Integrations & custom apps
Shopify integrations for Xero, ERP and warehouse systems.
Shopify integrations for Xero and other ERP, accounting, warehouse and inventory systems, so orders, stock, payouts and GST stop being re-keyed between screens.

The problem
Every re-keyed order is a future discrepancy.
Most growing Singapore retailers end up with Shopify at the front and other systems behind it: Xero or another accounting package, an ERP, a warehouse. Xero's own Shopify integration imports a sales summary without Singapore sales tax, so GST has to be taken from Shopify separately, and errors are found at month end.
We build the connections properly: a written data contract, a clear source of truth for each field, logging for every sync and alerts when something fails. We already run this kind of integration for our own Shopify GTO app, which submits merchants' sales to mall GTO servers every day.
What we do
What's included.
- 01
Xero, ERP and accounting sync
Online and POS orders, payouts, refunds, GST, products and prices exchanged with Xero or the system you already use.
- 02
Multi-location inventory
Stock levels synchronised between warehouses, outlets and Shopify locations.
- 03
Order routing
Orders passed to warehouses or 3PLs and fulfilment status returned to Shopify.
- 04
Custom Shopify apps
Private or public apps that add workflows Shopify and existing apps do not cover.
- 05
Scheduled jobs and middleware
Reliable background processing with retries, so a timeout does not lose an order.
- 06
Monitoring and runbooks
Sync logs, failure alerts and documentation your team can follow.

Questions
Asked often.
Does Xero's Shopify integration handle Singapore GST?
Not fully. Xero states that its Shopify integration imports a sales summary but does not account for sales tax in Singapore, so tax data has to be taken from Shopify (October 2026). A custom integration can carry 9% GST into Xero with each sale.
Can you connect Shopify to our ERP?
Yes, where the ERP can exchange data through an API, a file export or an existing connector. We first map which system owns each field, then choose a connector or a custom build.
Should we use an existing connector or a custom build?
Use an existing connector when it covers your data and volumes; it is cheaper to own. Custom work makes sense when the connector forces your operation to change, or when no connector exists.
What happens when Shopify changes its API?
Shopify releases new API versions quarterly and supports each for a limited period. Integrations need scheduled updates; we include this in support arrangements.
Can you work with our in-house IT team?
Yes. We agree the data contract with your team and document the integration so it can be maintained on either side.
