Answer
Typical gaps show up in slow close cycles, weak drill-down from summary numbers to source transactions, limited separation-of-duties reporting, spreadsheet-heavy reconciliations, and audit trails that are technically present but difficult to assemble. Those problems usually matter more than whether the interface feels modern.
Buyers should ask finance and audit stakeholders which reports take too long, which controls are hard to prove, and where manual work still carries too much risk. That list is what the software decision has to solve.
