CFO services for startups, without the full-time hire.
Excello's CFO services for startups and small businesses give you a senior finance specialist
part-time, for the forward-looking work: cash forecasts, financial models, budgets and the
numbers behind big decisions.
The work is built on your live QuickBooks, Xero or Odoo numbers, and your questions are
answered within one business day.
The finance decisions have outgrown the bank balance. You can see what's in the account
today, and not what it means for the hire you want to make, the price you haven't raised or
the expansion you're weighing.
You've looked at what a full-time finance lead costs and the number doesn't work yet. So
you're the one building the spreadsheet late at night, and you're not confident in it.
Once the work is handed over, the model is kept current by someone else, the cash forecast
updates without you touching it, and the decision you've been circling gets a number.

What are fractional CFO services?
Fractional CFO services meaning
Fractional CFO services are a senior finance professional's time and judgment, bought
part-time for an ongoing engagement, not as a salaried hire.
The role is about what happens next. A fractional CFO owns the financial model, the cash flow
forecast, the budget and unit economics, and the analysis behind decisions like hiring, pricing
or investing.
The role reads the output of bookkeeping and the monthly close, and turns it into a plan.
Excello's finance specialists work inside your existing QuickBooks, Xero or Odoo file, so the
model runs on your live numbers.
Your bookkeeper tells you what happened. A CFO tells you what it means, and what to do next.

How much do fractional CFO services cost?
Pricing
Fractional CFO services cost a fraction of a full-time hire, and the exact figure depends on
how much senior time you need and which parts of the scope you want.
Excello quotes CFO work before it starts, based on:
Scope. Cash forecasting only, or budgets, unit economics and planning as well.
Complexity. One entity and one revenue line model faster than several of each.
Timing. Busy periods, such as a budget cycle, may need more time for a while.
The books. A ledger that needs catch-up work first is quoted separately.
Selling online? Ecommerce CFO services add profit per order after
ad spend and margin by product.
Frequently asked questions
What are fractional CFO services?
Fractional CFO services give a company a senior finance professional part-time. That person owns the forward-looking finance work: the financial model, cash forecast, budget, unit economics and the analysis behind hiring, pricing and investment decisions.
How is a fractional CFO different from my bookkeeper?
A bookkeeper records what happened and closes the month. A fractional CFO uses those closed books to plan ahead: runway, margin, pricing, hiring and how capital should be spent. The work is judgment on the numbers, done in conversation with you.
Can we take CFO services without bookkeeping from Excello?
Yes. Fractional CFO work can be taken on its own. The forecast is only as good as the books under it, so your ledger is reviewed first, and anything behind can be fixed by your current bookkeeper or with Excello's catch-up work.
What do we need to provide?
Read access to your QuickBooks, Xero or Odoo, plus your payroll, payment and card tools where you use them. Beyond that, your plans and the decisions you are weighing. You keep admin rights to everything throughout.
How much do fractional CFO services cost?
It depends on the scope and how much senior time you need each month. Excello quotes CFO work before it starts, based on which parts of the scope you want, the complexity of the business and the state of your books.
