Most of the things on your lists can be done in Webflow Via 3rd party service (eg. Memberstack)
Webflow is a Visual development platform, which is still mainly targeted at building websites and not (yet?) applications/software. ERP is a complex system built on a solid application structure, so I don’t think Webflow is the right tool for that.
Did you ever encounter an ERP system which was built on the web?
Hi, Weilies. If you are looking some information about creating ERP, I can recommend you this guide: How to Build an ERP System From Scratch and Do It the Right Way. The steps to create this kind of application are well described here. I hope this will be helpful to you.
