A finance manager covering four weeks can receive every report, password and meeting invitation and still be unable to make the decision due tomorrow. Access transfers work. Authority transfers responsibility.
Interim finance leadership handover should specify which commitments the acting lead may approve, which exposures they must escalate and which forecast assumptions they may change. Give those rights an effective date, an end date and a named escalation owner before cover begins.
This proposal draws on Arron Bennett's published positions about CFO partnership and reducing dependence on one person. The authority categories and numerical illustration are original editorial applications, not an account of a Bennett engagement.
A chief financial officer title does not settle approval authority
An interim CFO, acting finance director or internal deputy may fill the same leadership gap with very different permissions. The title alone does not tell accounts payable whether a $20,000 renewal can proceed.
The CEO or managing director should approve the temporary authority. The outgoing leader supplies the live context. The acting lead confirms that the responsibilities are understood. The finance team then needs the same answer, in a record it can use during ordinary financial operations.
Questions that reveal a CFO's judgment help evaluate the person. The immediate handover question is narrower: what can this person decide on the company's behalf today?
Cash management needs three separate permissions
Use three categories when assigning interim leadership:
Commitment permission: spending or contractual decisions the acting lead may authorize within defined limits.
Assumption permission: forecast dates or estimates the acting lead may revise after checking evidence.
Escalation responsibility: exposures that need executive leadership or another designated approver.
These permissions should support existing internal controls. They do not replace the company's contractual, banking or compliance requirements. Where financial institutions require a separate authorization process, verify it rather than assuming the internal handover grants external access.
An acting lead may be allowed to update a late receipt in the cash flow forecast while still needing CEO approval to commit new cash. That separation helps cash flow management because an honest assumption change does not imply permission to spend against it.
Hypothetical: four weeks of cover, one renewal and one delay
Assume a four-week cover period includes a $20,000 vendor renewal. The company's fictional authority record lets the acting lead approve routine commitments up to $10,000; larger commitments need the CEO's decision. These are illustration amounts, not suggested universal limits.
Also assume $65,000 of available opening cash, $50,000 of already scheduled payments and a $30,000 receipt expected before the renewal. If the receipt arrives, cash after those payments and the renewal would be $25,000: $65,000 + $30,000 − $50,000 − $20,000.
If the receipt is delayed beyond both payment events, the same simplified sequence produces a $5,000 shortfall: $65,000 − $50,000 − $20,000. The example excludes other cash movements.
The acting lead should verify the delay, revise the assumption and escalate the changed exposure before the renewal decision. They cannot authorize the $20,000 solely because the outgoing leader expected it to be routine. The renewal's actual terms also need checking; an internal spending limit does not cancel an existing obligation.
When temporary cover reveals that nobody owns the next commitment, use the Profit & Tax Leak Check to examine that authority gap.
Business continuity depends on usable context
Provide access to the evidence behind the next decisions, not just financial reporting outputs. Complex financial information becomes useful when the incoming lead can see the payment event, customer evidence, contractual date and person responsible.
Cross functional teams also need to know where responsibility has moved. Sales should know who verifies a changed receipt. Operations should know who reviews a vendor commitment. Employees should know who resolves an approval that exceeds the temporary limit.
A successful transition needs open communication and ongoing support for exceptions. It does not require the outgoing leader to approve everything from leave. Name a backup escalation owner if the ordinary approver will be unavailable.
Bennett's fractional C-suite article covers the wider leadership model. This handover supplies the concrete financial guidance the temporary lead needs to act inside that model.
Financial performance needs an interim owner
The interim leader should oversee open approvals as well as reporting. Give each request a current status: within delegated authority, waiting for evidence, or escalated. A marketing request approved in an annual budget can still require cash review before its supplier is hired.
The leadership team should receive changes in those statuses rather than assume every item in the plan is authorized. That focus helps temporary finance cover serve the entire organization without pretending the deputy has every right associated with the permanent CFO role.
Review the permissions during the transition process
Financial planning, budgeting and financial analysis can continue during cover, but the next cash decision deserves priority over a promise of a seamless transition.
Set a review when a material assumption changes or an exposure crosses the approved boundary. In the hypothetical, the delayed $30,000 receipt triggers the review before the renewal is released. Risk management means noticing that the decision has changed, not maintaining the appearance of smooth reporting.
An authority map helps make delegated rights visible. Add the acting lead's temporary permissions to that map and agree how authority returns at the end of the cover period.
Before the next leadership handover, ask the acting lead to explain one commitment they may approve and one they must escalate. If the answers depend on guessing the absent leader's preference, bring that unresolved decision to the Leak Check.
Frequently asked questions
What must be agreed before the acting lead starts?
Commitment limits, assumption authority, escalation responsibilities, effective dates and the person who resolves exceptions.
Does an interim CFO automatically inherit the outgoing CFO's rights?
No. Confirm the actual internal permissions and any separate external authorization requirements.
Can the acting lead revise a forecast assumption?
Yes, if that permission is delegated and the revision follows verified evidence. Changing a forecast is separate from approving spending.
Who approves commitments above the temporary limit?
The named executive or backup approver in the authority record, rather than an assumed absent decision maker.
What should trigger an immediate review?
A material evidence change or exposure crossing the approved boundary, before the affected commitment is released.
Should the outgoing leader remain available for every approval?
No. Define the support they provide and a usable escalation route so ordinary decisions can continue during cover.
Does a spending limit change an existing contract?
No. The company must check existing terms and obligations before deciding how to respond.
How should temporary authority end?
At the agreed end date, with a recorded handback and review of unresolved decisions and assumption changes.
