CFO as a Service.
Finance leadership with the right modules.
Boost your financial performance with our tailored CFO and financial services designed specifically to scale and strengthen your business.

In brief
CFO as a service from nugrow is ongoing finance leadership on a part-time basis: bookkeeping, reporting and controlling, financial planning, liquidity management, investor and bank communication, and processes and systems – as modules that can be switched on and off individually. Billing is a monthly retainer, from a few days a month to three days a week. For startups from seed stage, scale-ups and mid-sized companies; German BAFA consulting subsidies can be combined with any consulting project.
Model: ongoing, part-time, modular – not a full-time CFO

When is Finance as a Service useful?
Which companies this is for
The finance function looks different in every business model. These are the starting positions we meet most often – and what we work on in the first few weeks in each case.
SaaS & Software
Recurring revenue that the books do not represent cleanly. ARR, accruals and cohorts have to be defined before the next investor examines them.
Finance for SaaS companiesE-commerce & marketplaces
Several payment providers, several currencies and a reconciliation that takes too long. Contribution margin per channel and working capital belong in one view.
Finance for e-commerceB2B companies
Long sales cycles and project business: down payments, accruals and a plan that follows order intake rather than the calendar.
B2C & retail
The margin is made in the detail. Returns, discounts and logistics costs belong in the contribution margin calculation, otherwise it stays unclear what a sold product really brings in.
Agencies & service providers
Revenue sits in projects. Without project controlling and clean accruals, you only find out afterwards which engagement actually paid for itself.

Frequently asked questions about CFO as a Service
What is CFO as a Service, and how does it differ from an interim CFO?
CFO as a Service means finance leadership is brought in from outside on an ongoing, part-time basis – billed as a monthly retainer, with only the scope you actually use being paid for. An interim CFO, by contrast, takes on the role for a fixed term and usually full time, most often because of a vacancy, a funding round or a transaction. Rule of thumb: a time-limited trigger at high intensity argues for interim, a permanent need below a full-time seat for CFO as a Service.
From what company size does the model pay off?
As soon as there are reporting obligations towards investors or banks, cash runway has to be answerable at any moment, or bookkeeping on its own no longer gives you anything to steer with. In practice that is often from the seed round onwards. The upper limit sits where complexity permanently ties up a full-time capacity – at that point a permanent hire is cheaper.
Which services are included and which are not?
CFO as a Service is bought in modules that can be switched on and off individually: ongoing bookkeeping, reporting and controlling, financial planning, liquidity management, investor and bank communication, and processes and systems. The retainer does not normally cover the annual financial statements, special projects and system implementations – those are quoted separately.
What does CFO as a Service cost?
The monthly retainer runs between EUR 2,500 and 15,000 depending on scope: a few days a month EUR 2,500 to 5,000, one day a week EUR 5,000 to 9,000, two to three days a week EUR 9,000 to 15,000. From around EUR 12,000 a month the model is level with the fully loaded cost of an in-house CFO seat. The full overview with day rates and a comparison calculator is on Pricing.
How quickly can we start working together?
The intro call is free and without obligation; after it you receive a proposal covering scope, retainer and term. Where the need is acute, someone from our network is usually ready to start within 24 hours. An orderly start that includes taking over bookkeeping and reporting normally needs two to four weeks of lead time.
What happens to our existing tax adviser?
They stay on board in almost every case. We work alongside the existing firm and take on the side it does not cover: steering, planning, reporting and the communication with investors and banks. Where ongoing bookkeeping is handed over as well, we agree the interfaces and the closing calendar with them beforehand.
How long does the contract run?
The monthly retainer runs on an ongoing basis; the term and the notice period are set out in the proposal. The scope can be adjusted through the modules, which can be switched on and off individually.
Does the knowledge stay in the company when the engagement ends?
Only if it is contractually agreed. That is why documenting the processes, handing over the models and the reporting structures belong in the scope of work – not in the final week. If the need grows into a full-time position, the handover to your own hire can be planned step by step.
