Luckily we chose Dear Systems over Tradegecko for our second business.
This is how an inventory management platform should work. It's easy and intuitive, and customer service is fantastic.
To be fair, Tradegecko is easy to use as well, but unfortunately the data does not synchronise between Shopify/ TG/ Xero consistently and we have to spend many hours manually reconciling sales.
Dear systems has caused us no headaches which is what you want as a small business owner.
