CFO handover and vacancy: choosing the role and securing responsibility

Interim CFO, an internal stand-in, or extra operational capacity? A decision guide with six handover packages, clear responsibilities and acceptance criteria — plus the German commercial-register and signing-authority steps that decide when the handover is actually complete.

CFO handover: securing responsibility and choosing the right role

The decision in short

In a CFO handover the first question is who is able to decide before the next critical deadline. Where finance leadership is missing, an interim CFO is the answer. Where the leadership is in place and the shortfall is operational, reinforce accounting or FP&A specifically. An internal stand-in works where authority, experience and capacity demonstrably suffice.

A note for readers outside Germany

Two German particulars decide when a handover is actually finished, and both take longer than people expect.

  • Statutory office versus delegated authority. If the departing CFO was also a registered Geschäftsführer — a managing director in the statutory sense — then removal and appointment are corporate acts: a shareholder resolution, notarisation, and a filing with the commercial register. Until the register is updated, the register still shows the departing person. An interim CFO is normally not appointed to that office; they act under a service contract with delegated authority, which is why that authority has to be written down rather than assumed.
  • Signing and banking powers follow the register. German banks and counterparties work from the commercial-register extract and from registered signing authority (Prokura). A change of authorised signatories is therefore not a same-day matter — plan for the register filing to take weeks, and make sure someone with valid authority can release payments in the meantime.

How an interim mandate is structured contractually in Germany — including the bogus-self-employment question that shapes it — is covered in the interim CFO contract in Germany.

Which solution fits the situation

  • The CFO leaves and decisions go unmade: an interim CFO with clear responsibility for the team, cash, closing priorities and communication. Management settles decision and release rights before the start.
  • Finance leadership is in place, but bookkeeping or closing work is piling up: interim accounting or qualified closing support. The CFO keeps responsibility for priorities and approvals.
  • The closing figures are there, forecast and analysis are not: interim FP&A with a driver register, plan-versus-actual analysis and a fixed forecast date.
  • Operations run, but finance leadership is needed regularly on a part-time basis: a fractional CFO or a properly scoped CFO-as-a-Service arrangement — the models are compared in interim CFO, CFO as a Service or a permanent hire.
  • Existing leadership can stand in: an internal arrangement with written authority, relief from the current workload, and a named escalation route.

Secure the next critical deadline first

List payments, closing submissions, shareholder and lender dates and any live transaction. For each one, name the preparer, the reviewer, the approver and the deputy. Start from the deadlines that are genuinely next; a generic two-week list must not push an earlier date out of view.

Check authorised access and powers through the proper IT and banking processes. Personal passwords are not a substitute for a handover. Where the departure is unplanned, management arranges permitted access together with IT, the banks and the advisers.

Six handover packages with a verifiable outcome

  • 1. Responsibility: tasks, authority, deputies and contacts. Evidence: an approved responsibility list.
  • 2. Cash: reconciled bank balances, payments falling due and the current forecast. Evidence: a dated version with assumptions and open questions.
  • 3. Closing: the last completed period, account reconciliations and backlog per entity. Evidence: a closing calendar and a prioritised list of open items.
  • 4. Reporting: recipients, metric definitions, data sources and submission dates. Evidence: the last reporting pack with traceable reconciliations.
  • 5. Planning and projects: the current forecast, key assumptions, decisions and project dependencies. Evidence: a version with owners and the next decision date.
  • 6. External relationships: the responsible people at shareholders, banks, tax advisers and auditors, plus documented agreements. Evidence: a contact and deadline register referencing the underlying documents.

Test the handover against real work

Have the successor produce the next reporting pack from the documented sources, or update the cash forecast. The outgoing owner explains the exceptions and works through with the successor where information is missing. Management signs off the agreed scope.

An item counts as handed over when documentation, authorisation and the ability to actually do the work are all present. “File sent” does not qualify. The record shows the item, the outgoing and incoming person, the date, the evidence, any open question and who is closing it.

When a CFO change meets a closing backlog

Separate the leadership task from clearing the backlog. The interim CFO prioritises and decides; the accounting team works agreed packages. FP&A flags provisional actuals and takes approved corrections into the forecast. That makes it visible which capacity is genuinely missing. How to tell which bottleneck you actually have before adding people is set out in closing backlog and fast close.

What belongs in the briefing

  • The next critical deadline and the consequence of missing it.
  • Entities, systems, team capacity and data access.
  • Decision rights and the results actually expected.
  • Scope, fee, review dates and the handover to the permanent successor.

First profiles and an actual start are two different steps; the start is agreed after selection and engagement. Duration and overlap follow from the brief and the results. On cost: what an interim CFO costs in Germany and pricing and billing models. On selection: how to find an interim CFO.

Common questions

When is an internal stand-in enough?

When a named person can take the decisions within the agreed scope, the operational team has enough capacity, and the tasks ahead match the experience available. Test those conditions separately for closing, cash and shareholder communication.

When does a CFO handover need an interim CFO?

When finance leadership is unfilled, or when material decisions, team leadership and external communication have to be carried as well. Where only capacity for bookkeeping or forecasting is missing, targeted support in accounting or FP&A can be enough.

Does an interim CFO in Germany have to be appointed as a managing director?

Normally not. An interim CFO usually acts under a service contract with delegated authority rather than as a registered Geschäftsführer. Appointment to the statutory office is a corporate act requiring a shareholder resolution and a commercial-register filing, and it changes the liability position — so it is a deliberate decision, not a formality.

What happens to bank authorisations during the change?

German banks work from the commercial-register extract and registered signing authority. Changing authorised signatories takes a register filing and therefore weeks, not days. Make sure that in the meantime someone with valid authority can release payments.

How do you know the handover is complete?

The successor has the necessary permissions, knows the deadlines and the open decisions, and can run the agreed core processes from the documentation. Anything still open stays in the handover record with an owner, a date and an escalation route.

How long should the overlap be?

It follows the next reporting and decision cycles, the number of entities and the state of the documentation. Rather than a blanket number of weeks, agree specific handover outcomes and the availability of both people.
