  • Completely automate your Shopify store, saving you money
  • Save hours of work by eliminating manual transfers between Shopify and your other apps
  • Connect apps including accounting, fulfillment, inventory, CRM and email marketing.

OneSaas gets Shopify working happily with your accounting, fulfillment, shipping, inventory management, CRM and email marketing apps.

Automatically transfer information like orders, stock levels, contacts, shipping labels and shipping tracking.

Here’s how it works...

When a customer places an order on your Shopify store…

Accounting – the invoice and customer is created in your accounting application. The payment is created and the stock levels are updated. e.g. QuickBooks Online, Xero

Fulfillment – the order is received by your fulfillment provider, and the product is packed and shipped to the customer. The tracking number will be updated in Shopify. e.g. Shipwire

Shipping – the shipping label is automatically created. The tracking number will be updated in Shopify. e.g. ShippingEasy

Inventory Management – stock levels are updated in your inventory management app and your online store(s). e.g. Unleashed

CRM – sales and customer information is passed to your CRM so you have a 360-degree view of your customer. e.g. Salesforce, Zoho CRM

Email Marketing – the contact is added to your email marketing list. e.g. MailChimp

Choose to connect just one or all of the above applications to Shopify.

Good app. Works well and easy to use.



Onesass is a great addition for our business and it allows us to connect many things together and automate so much.

The support team has been great if I have had to contact them and would recommend anyone looking for a great tool for connecting all your services up in one place.


Fantastic product.

Really makes it so easy, I just run it automatically every morning and if I need to during the day.

Means I can be away from the office without having to worry about orders getting fulfilled.

On the rare occasions I have contacted support, they have been excellent.

Very happy customer.


The support from Johnny at One Saas has been nothing short of amazing. Very quick to reply to my numerous questions while getting 3 Shopify sites all hooked up to one accounting system. Nothing was too much trouble. Everything was explained clearly so that we knew what we could and could not do and why. First class support. The app is working well for us too, syncing all our inventory across all sites every hour to avoid the embarrassing 'sorry we've already sold it elsewhere'.


Works perfectly, OneSaas support are helpful. Only limitation that we found annoying was you can't set up a workflow where OneSaas tries to push an order from Shopify to your accounting system (Saasu in our case) as a Tax Invoice first, then if stock is not available (negative value) then it will push it through as a Sale Order. You can only choose either to sync all orders as Tax Invoices or Sale Orders. Then you either have to go into our accounting software and manually change all the orders into Tax Invoices or wait for pre-ordered stock to arrive before OneSaas will push the orders into Saasu as Tax Invoices. Would give 5/5 if this became a feature.


Fantastic product and exceptional service. Onesaas Support is always fast and helpful to assist with any technical questions. The middleware has completely automated our inventory management and accounting syncing :)


Great support :) Adela was very helpful, responsive and patient.


Just added a 2nd connection. Support chat is super and Adela was very helpful in making it happen.


Great time-saver. Helpful customer service.


Would not want to be without it. Saves so much time every day. Support is great. Would give 5 stars if they could import gateway fees and import the prefix along with the order number. Would give 10 stars if they could handle returns/refunds.
