How to improve Marketplace Connect inventory sync speed on Shopify?

[easternsports]

We are new to Shopify having migrated from woocommerce for a number of reasons. However, we are a huge eBay seller of pre-owned equipment. This of course means that we have one unique item of each thing that we sell. Once it's sold, it's gone forever. So inventory management is super important across multiple channels. When using woocommerce we had a plug-in that would sink in real time, meaning a second if that. After a sale was made on another channel. All the other channels would be updated immediately. Now using the marketplace connect app it is taking up to an hour to sync our inventory between channels. Marketplace. Connect support. Keeps trying to blame eBay for this. However, clearly it is not an issue with eBay given the fact that our plug-in from woocommerce worked within a second of an inventory change.  This is definitely and has already led to false orders where someone ordered off of eBay and then also ordered the same item on Shopify. Which is actually the better situation because we wouldn't get dinged by eBay. However, it is now also happened when they purchased on Shopify and then the item was sold on eBay as well. 30 minutes later. Of course we had to convince the buyer to cancel their order so that we would not get dinged. This is not a good way to run business. And I am shocked to find that I would be the only one with this issue. Has anyone else had a similar experience? Is there a better way to sync inventory real time? I believe the app was originally made by Codisto And all of the marketing and documentation would suggest real-time inventory sync.

How can you make their sync faster?

There is a callback endpoint provided by ebay which gives us real-time feed for inventory-related updates, so the responsibility is on ebay to provide us updates.
If you want we can connect over email to discuss the problem in more depth and we can build a private for your store
