Local authorities typically have:
payroll & expenses
hr - benefits, hiring, reviews, time, approvals, reporting
stock, consumables and stuff they give out/distribute
distribution & warehousing of stuff
purchasing, goods receipt, accounts payable
finance & management accounts
reporting on anything and everything
orders, fees, subscriptions, taxes, receipts
CRM for handling "customer contact" e.g. green bins, pest control, pemits
Think of anything that every type of business might do, somewhere in local authority somebody will be doing just that. At least until it all gets reorganised/split up/tendered/outsourced/merged/abolished.
Maybe using the word enterprise in association with the stereotypical council is a bit hard to swallow, but it's still the same processes. Even if somewhat twisted and mangled into their own worldview.
