Put/Receive stock in

Very new on here! We are looking to use Veeqo for our b2c channels and need it to work in conjunction with our ERP system.
APIs seem to be somewhat limited, so wondering if anyone has a slick way to report arrival of new stock. Kind of what the veeqo app does on Booking In transaction.

Essentially, I’d like to tell Veeqo to increase/decrease stock by X once we receive/scrap stock in our ERP system. Veeqo would still be stock master, so I can’t just override the existing qty with X from my ERP. It needs to be an addition to existing.
