We are experiencing issues with Breww API syncing with Sellar.
There are individual SKU’s which are being combined into 24x500ml cans and therefore the stock in Sellar is showing incorrect as these are only sold in our retail channels (taproom / webshop).
Fortunately this is already a feature. It sounds like you are using the Theoretical max stock level and would benefit from using the Available stock level. More on this can be seen at Understanding stock levels.
If you edit the integration config, you should be able to switch to the other stock calculation method.
If this doesn’t cover what you need, please let me know, otherwise, I’ve set this thread to auto-close in 2 weeks. Cheers.
