[Tricky] Is is it possible to sync the database of a bookstore with its E-Comm site on Webflow?

So I was discussing prospects of redesigning the website for a local bookstore here in my city. The old site is pretty outdated with a crappy UX/UI.

The old site didn’t have an e-comm facility. So I’m tasked with creating and e-comm site for the store. The owner wants the function where the inventory details remain synchronized between their POS(they are probably using asp.net for the POS) and the E-comm website. The primary attribute which needs to be synced is the number of copies of a book in stock. They want to avoid backorders.

So can it be done using Webflow CMS?
