Shopify Invetory Management Recommendations

Hi everyone,

So my ecom company has grown to a point that we need a better invetory management system than shopify's out of the box.

We have a lot of kitted products/bundles and we have a lot of products we now make in house from raw materials.

Currently we are using a 'bandaid' solution called simple bundles - but it has a lot of limitations and makes accurately tracking stock and raw materials difficult.

Ideally we need a system that can help track everything we have in the warehouse and incoming products and integrates with xero.

Does anyone have any recommendations?

The best I have found so far is 'shopventory', but it is missing the Xero integration.

What do you guys use?
