5 integrations every growing e-commerce store needs

A store doing thirty orders a month runs fine on manual work. At three hundred, the same processes quietly consume a full-time role. These are the five integrations that consistently return the most time, in the order we usually build them.

1. Inventory synchronisation

If stock lives in more than one place — a warehouse system, a physical shop, a marketplace listing — it will drift. Overselling costs you refunds and reviews; conservative buffers cost you sales. A near-real-time sync with a single source of truth removes both. Start here, because every other integration depends on trustworthy stock data.

2. Accounting and invoicing

Orders, refunds, payouts and fees flowing automatically into your accounting system. The value is not only the data entry saved: it is closing the month in two days instead of two weeks, and knowing your actual margin per order rather than estimating it.

3. CRM and marketing automation

Customer records enriched with order history let you segment properly — repeat buyers, lapsed customers, high-value first orders. Abandoned-cart and post-purchase flows are the highest-return automation in e-commerce, and both need clean order data in the CRM to work.

4. Shipping and fulfilment

Label generation, carrier selection, tracking updates and returns. Every one of those touched manually is thirty seconds per order that scales linearly with growth. Automated tracking notifications also cut "where is my order" support tickets substantially — typically by half.

5. Customer support

Your support tool should show the customer's orders, shipments and refunds on the ticket. Agents stop switching tabs, first-response times drop, and answers get more accurate. This is a small integration with an outsized effect on customer experience.

Build order matters

Inventory first, because bad stock data poisons everything downstream. Accounting second, because it is the one with a hard deadline every month. Then CRM, shipping and support in whichever order matches your current pain.

Measure the manual minutes before you automate. If a process costs less than two hours a month, leave it alone.

A note on no-code

Zapier and Make handle the simple end of all five of these well, and we recommend them regularly. Move to custom integration when you need two-way sync, when volume makes per-task pricing painful, or when a silent failure would cost you real money.
