How to Connect Shopify and QuickBooks with OneCart

A busy Shopify store produces a steady stream of orders that all need to land in your books. OneCart connects Shopify to QuickBooks so every order flows through automatically as an invoice, with the customer and totals in place, and your other sales channels can feed the same accounting view from one dashboard.

Orders to invoices

Each Shopify order is written to QuickBooks as an invoice with its line items, customer, and totals, so your sales are recorded without re-keying.

Customers

Customer details from your orders are added to QuickBooks, so your contacts stay in step with who is buying from you.

Hands-off books

Once your income account and tax handling are mapped, new orders flow to QuickBooks on their own, so month-end is not a data-entry marathon.

Connect Shopify and QuickBooks in three steps

STEP 1

Connect Shopify: go to Settings > My Platforms > Manage Connections and click Add shop for Shopify. Install the OneCart app when Shopify prompts you, log in to your Shopify store, then log in to OneCart. A green banner confirms Shopify is connected.

STEP 2

Connect QuickBooks: open the accounting integration settings in OneCart and choose QuickBooks. You are taken to QuickBooks to approve OneCart's access and pick the company you want to sync to, then returned to OneCart.

STEP 3

Set how orders map to QuickBooks once, choosing the income account and tax handling, and OneCart writes each Shopify order to QuickBooks as an invoice from then on, so your sales sit in your books without manual entry.

AUTOMATED ACCOUNTING SYNC

OneCart writes your Shopify orders straight into QuickBooks, and does the same for every other channel you connect, so your whole business lands in one set of books instead of one store at a time.
