Does reconciliation suffer most when finance teams scale faster than their processes?

In high-growth companies, finance teams often expand rapidly to keep up with transaction volume. What does not always scale at the same pace are reconciliation processes and controls. The result is more people working on the same accounts, more handoffs, and more room for inconsistency.

Even with decent tooling in place, the underlying workflows can become fragmented as teams grow. Some finance orgs use tools like Collatio Accounts Reconciliation software to keep workflows more consistent, but scaling teams still seems to introduce new failure points.
