InKnotts Wine review for SumUp Stock Sync

May 21, 2026

Does not work, having failed to sync for weeks and being told to force sync - it has now apparently synced however the stock levels on my shopify store have not altered to match the back office stock level. Customer service is utterly shocking, they don't seem to understand their own system and seem to only want to upsell everything. Make your app work! I will tell every business to avoid at all costs. spent £800 on till system and £58 pm on fee for a service that doesn't work
