Controller vs. CFO: who owns which decision?
The controller owns the reliability of the books and the close. The CFO uses those numbers with operating assumptions to recommend what the business should do next. In a smaller company one person may wear both hats. The handoff between the jobs still matters.
Look at one inventory purchase from both seats
| Question | Who leads the answer? |
|---|---|
| Did we receive what the vendor billed? | Controller: match the receipt, purchase order and invoice; check quantities and period cutoff. Operations confirms what actually arrived. |
| Does the margin report include the right costs? | Controller: reconcile inventory and cost of sales to the ledger and explain the allocation. The CFO uses that explanation to assess the decision. |
| Should we buy another batch now? | CFO: compare the discount with cash tied up, spoilage or obsolescence, expected collections and the cost of financing. The owner approves the commitment. |
Find the first unanswered question
If the owner asks why margins fell and nobody can trace the change to transactions, start with controller work. If the team can explain the decline but nobody models whether to raise prices, drop a job or finance a larger order, the missing work belongs to the CFO. A late close and an unanswered investment decision may require both roles, in that order.
For your next review, write down one number the controller will validate and one choice the CFO will recommend. Give each a deadline. If the same name appears twice, check that the person has enough time for both jobs and that someone else can review the underlying work.
