Full ERP? For what size organisation? I expect the finance team are using a 'real' ERP behind the scenes and posting the values from the custom system manually every month, copying and pasting from it almost as if it was an old fashioned day-book.

Exactly this.
At a prior startup years ago, I noticed that the accounting & finance team was always in the office late along with the engineers. I would ask them to show me the spreadsheets/models/forecasts they were working on and how it all worked because it seemed so important to the CEO & CFO.
I casually commented I could build this more effectively in code, and a half dozen people laughed at my joke. They then sat me down and showed me things like journal entries, how deferred revenue is managed or annual subscriptions are recognized. There were dozens of examples of scenarios that were completely unique from each other and required tools to allow them to capture these things and roll them up into a consistent P&L and income statement, balance sheet, and cash flow statements all adding up nicely.
And you realize that it's completely impossible for a company to capture all of this correctly "in flight", and things are going to be messy and wrong. ERP's have decades of experience capturing the nightmare that is actually managing a business and it's not sexy, but it works better than most alternatives.
