the industry we try to make for them their first inhouse app, is having a lot of data that we need to import to the app. (machines, workers, materials, products, etc). The problem is that they want to give them to us in excel files, instead of making data entry. So thats ok for start, but after some point of complexity and relations we figured out that it turns to be a deadend.
How do you manage situations like this, with huge old fashion companies??
