Learning the client
Client rules in place
Client rules
Month one learns the chart of accounts, recurring accruals and vendor patterns. By month four they are that client's rules.
The evidence trail
Every close keeps its reasoning and source documents, month after month. That history becomes the audit file.
Free seats for auditors
Auditors, boards and investors read the close at no cost, and see monoclose working on real books.
