Not a browser-based app. It was an extremely customized peoplesoft. And the whole project ended in a lawsuit. We had learned a bit, so we took our time to get our duck in a row, and it was about 4 years before we started fresh with a different vendor.

Was that project worth it? We didn't have much choice. Our old ERP was close to 35 years old, and no longer supported, so we were paying large sums of money just to get annual compliance updates for state & federal requirement. The new system is fine, does what it needs to do, but it's a monolithic ERP system: It does just about everything, but it's mediocre at all of it with most of it's tech perennially 4 to 7 years out of date with the best of breed. So, in the areas where we really need best of breed, we bought that and integrated it into the ERP, which is considered the "system of record". So it's fine, it works, I guess. The real kicker though is that the system we ultimately chose, while not an Oracle product, still required an Oracle DB. Fortunately we don't actually deal with Oracle as a vendor though. Our vendor is basically a VAR.
