I do ERP and the thought of replicating it in Excel… yikes. For a big company you’ll need a team of hundreds and a huge surplus of sanity, and you’ll still have a worse outcome.

An ERP is basically a database with an interface with business logic built in. Certainly not something you want to do in Excel.

When people talk enterprise they are talking 2000+ person companies. They are not doing their ERP payroll etc using excel.
