Shopify integration for the rest of your business
A Shopify integration moves orders, stock and tracking numbers between your store and the other systems you run on, so nobody copies an order out of the Shopify admin by hand.
We connect Shopify stores to marketplaces, carriers, invoicing and accounting. The rules are yours: which orders ship from where, which carrier takes which parcel, what goes on the invoice.
What a Shopify integration does
The jobs we connect most often. Each one replaces a screen someone copies from today.
Orders to the packing table
Paid orders appear in one queue with everything the packer needs. The label is booked at the carrier and the tracking number is written back to the order.
One stock count
Shopify, eBay and Etsy draw from the same count, so a piece sold in one place comes off the others before someone buys it twice.
Invoices and accounting
The order becomes an invoice in your invoicing or accounting system, QuickBooks included, with the tax line your accountant expects.
Your back office
A warehouse sheet, a supplier feed or an ERP kept in step with the store, in whichever direction the data has to flow.
The same work on our own order desk
Our own parts business sells on eBay, and its order desk does what a Shopify integration does: orders come in every five minutes, each one is matched to the box that holds the part, the label is booked with the carrier, and the tracking number goes back to the marketplace on its own.
The invoice goes out with the VAT line worked out per buyer, and a daily list shows anything that shipped without one. The full story of that order desk
An App Store app may be enough
If one popular app does the step you need, use it. We would tell you that on the call, and you keep your money.
Custom pays when the step needs your own rules, when the system on the other side has no app, or when a double send costs money. When each one fits
Questions
What is a Shopify integration?
Code that connects your Shopify store to another system through Shopify’s API, so orders, stock, customers and tracking numbers move by themselves. A custom one also applies your own rules on the way: which warehouse, which carrier, which invoice.
Can you sync Shopify with eBay and Etsy?
Yes. We keep one stock count across Shopify, eBay and Etsy, so a piece sold on one channel comes off the others, and all orders land on one screen for the people who pack.
Can you connect Shopify to our ERP or accounting?
Yes. We connect Shopify to QuickBooks, and for an ERP or another back-office system we read its documentation against your steps on the call before we quote. See QuickBooks integration.
Is an app from the Shopify App Store enough?
Often it is, and we will say so on the call. A custom integration pays when the step needs your own rules, when two apps fight over the same data, or when nothing in the App Store connects the system you run on.
What does a Shopify integration cost?
We price it on a call, per milestone, after reading both sides’ documentation. Most integrations are part of a bigger build; see what custom software costs.
Does it still work when Shopify changes its API?
That is what care covers. Shopify moved its Admin API from REST to GraphQL for new apps [1]; changes like that are ours to follow, not yours.
