Sellbrite

App only allows 100 variants to be imported from Shopify, despite that limitation being lifted from Shopify itself months ago. Agents had no idea about this until we notified them, and first tried to argue that it wasn't their limitation... They "opened a ticket" and assured they'd update as the ticket progresses, but we have heard nothing from them other than when we reach out for updates.

Was told when we did our October check-in that they were about to roll out testing, and yet, still nothing. Several variants have been managed manually for months now. An absolute nightmare for our small team, and now we are having to shop around for an inventory manager that can actually manage our inventory... Very disappointed in what was once a decent service.

Great little app, I have been using it for years with few issues. It's the only app around with a useful free plan that can sync your Shopify store inventory with Etsy and Ebay. Very easy to use.

Products are syncing when we publish on sales channel for the first time.
After that there is no real time syncing of price and inventory. So we had oversold products.
Support is very fast but we only get basic and generic feedback.
Videos are very basic.
Nobody really looks at our issue.
Cannot resolve issues.

I have now received the information that free plans sync only every 2 hours and paid plans sync every 15 minutes. This clarifies my issue, but I had not seen anywhere this information before. With free plan you still have the risk of overselling if you get an order within the 2 hour sync cycle. I changed my rating to 3 stars.

New update: this app is definitely not syncing correctly. We had 2 orders on eBay for products no longer available. We had to cancel the orders. Not good for customers, not good for complying with eBay policies. It looks like the "eBay listings" on the app do sync with listings on my "base" inventory downloaded on the app. But the eBay listings on the app do not actually sync with products already listed on eBay, after having listed them on eBay from the app. The sync only happens the first time they are listed on eBay, but no sync afterwords with eBay. These orders were in fact no longer in stock since August 25!! Still showing available on eBay. No longer showing available from the products downloaded to the app.
Avoid this app to avoid embarassment with customers and risk for not complying for eBay rules. This can be very costly.
We have about 20,000 products, of which 622 on eBay. Impossible to keep checking each and every product one by one.
