Fractional CFO Onboarding: 6 Things to Hand Over in 30 Days

Fractional CFO onboarding fails the way most new hires fail: nobody prepared the first week. The CFO shows up, and two weeks go to chasing passwords, finding last year's return and asking who actually closes the books.

You are paying for a senior person's time. Here are six things to hand over in the first 30 days.

The firm that fits this topic is System Six, a Seattle bookkeeping and fractional CFO firm for businesses with $1 million to $10 million in revenue, including companies modernizing their finance function after an acquisition. It is covered near the end. System Six is a paid featured member of Sam's List.

1. Fractional CFO Onboarding Starts With Access, Before Day One

The short answer: give your fractional CFO read access to your books, bank accounts and payroll system before the first meeting. A fractional CFO's time is billed in hours or a monthly fee, and access delays burn both.

That means the accounting system, bank and card feeds, the payroll provider, and the folders where contracts and loan agreements live. A fractional CFO access checklist is short, and every item on it saves a day. Start with read-only access.

The limitation: access is not understanding. If your books are messy, the first weeks go to learning why, and that is a cleanup bill, not a strategy bill.

2. Hand Over Three Years of Tax Returns and the Current Budget

Give your fractional CFO the last three years of business tax returns, and personal returns too if you are a pass-through owner and the numbers overlap. Returns show how income and expenses were classified and where the books and the return disagree.

Then hand over the current budget. If you do not have one, say so plainly. "We never made a budget" is useful information. Add prior forecasts and investor updates, which show what you told others the business would do.

The limitation: returns are built for tax rules, not management decisions. Depreciation and owner compensation can make a return look different from the business, so treat it as one input.

3. Put the Debt, Covenant and Lender Reporting Calendar on the Table

List every loan, line of credit, equipment lease and credit card with a balance, with its rate, maturity and any reporting duties. If a lender requires covenant compliance, such as a minimum cash balance or a debt service ratio, give the CFO the actual loan agreement, not your memory of it.

Then build the lender calendar: which reports are due, to whom and when. A missed report can start as a form and end as a fee or a waiver request.

The limitation: a fractional CFO can organize and monitor debt terms, but cannot renegotiate them without your authority and often a lender's consent. Legal interpretation of a loan agreement belongs with your attorney.

4. Decide Who Owns the Monthly Close

The monthly close is the process that turns bank activity into reliable financial statements. Someone has to own it, and the answer in a lot of small businesses is "kind of everybody," which means nobody.

Decide in writing who reconciles accounts, who reviews the work and by what day the books are done. If the fractional CFO's firm will take it over, set a date.

This is the line between a fractional CFO and a controller. The short version: a CFO plans from the numbers and a controller owns the numbers' accuracy. Either can be part time.

The limitation: if the person who closes the books also reviews them, errors survive. Separate the two where you can.

5. Set Decision Rights and a Meeting Cadence

Decision rights are the unglamorous part of fractional CFO onboarding, and the part owners skip most often. Decide what your fractional CFO can approve alone, what needs your sign-off, and what goes to a partner, board or investor.

Then set the cadence. A common starting point is a weekly check-in in the first 30 days, a monthly financial review and a quarterly planning session. Put it on the calendar now, because a meeting "to be scheduled" tends to wait until something goes wrong.

The limitation: a fractional CFO advises. Authority stays with you unless you decide otherwise in writing, and part-time attention means slower responses than a full-time employee.

6. Fractional CFO Onboarding Ends With a First Deliverable and Scope

Fractional CFO onboarding ends when both sides can name the first deliverable. It should be small enough to finish in the first 30 days and specific enough to judge. A rolling 13-week cash forecast, a cleaned-up budget versus actual report, or a monthly dashboard of five numbers are the usual candidates.

Write down the scope too: what the monthly fee covers, what is billed separately and who the CFO reports to.

A reasonable pace for the fractional CFO first 30 days: access and handoff in week one, a review of the books in week two, the first deliverable agreed in week three and drafted in week four.

The limitation: one deliverable is a test, not a transformation. If the first one is late or thin, ask why before you ask for more.

System Six: A Seattle Fractional CFO Firm for Post-Acquisition and Growing Companies

System Six is a bookkeeping and fractional CFO firm based in Seattle. Founded in 2009, it has about 41 employees and serves clients nationwide, with a stated focus on businesses generating between $1 million and $10 million in revenue. Its profile also describes help for organizations modernizing a finance function after an acquisition, and says System Six was itself acquired by a searcher in 2021.

A clean handoff matters most after an acquisition: new owners inherit books, bank access and lender terms they did not set up. A firm that does both bookkeeping and fractional CFO work can handle the close and the planning from one team.

System Six does not yet have enough verified reviews on Sam's List for a count to be meaningful, so we do not cite one. Judge the firm on its stated specialty, tenure and team size, and ask for references from clients like you.

The limitation, plainly: System Six lists a $1 million revenue minimum and fees from $800 a month, so earlier-stage companies are outside its range. A firm of this size may also assign you a team member, so ask who your day-to-day CFO would be and how much of their time you would get.

Frequently Asked Questions

What should be on a fractional CFO access checklist?

Read access to your accounting system, bank and card feeds, and payroll. Add three years of tax returns, the current budget and loan agreements. Start read-only, and grant more once scope is agreed in writing.

What happens in the fractional CFO first 30 days?

Typically access and document handoff, a review of the books to find gaps, agreement on the first deliverable, and a first draft. Weekly check-ins are common at the start. The exact pace depends on how clean your records are and what you hired the CFO to do.

How long does fractional CFO onboarding take?

Often about a month to get access, records and scope settled, with the first deliverable landing near the end. It runs longer when the books need cleanup or when lender and investor documents are scattered. Preparing the six items above before day one is the best way to shorten it.

Who should own the monthly close during onboarding?

Decide in writing, and name a person, not a team. It can be your bookkeeper, your accountant or the fractional CFO's firm. Ideally someone other than the preparer reviews it. Until the close is reliable, forecasts built on it will not be.

If you are about to hire, send your prospective firm the six items above before the kickoff call and see how they respond. You can browse fractional CFOs on Sam's List, including the firm above.

How This Firm Was Chosen

You should be able to check our work, so here is how this post was built.

The pool. Every firm named is a vetted Sam's List member in our featured program, with a live public profile. This is not a survey of every fractional CFO, and many Sam's List firms outside the featured program could fit this topic.

How it is organized. The six items follow the first 30 days. One firm is written up because its stated focus covers bookkeeping, fractional CFO work and post-acquisition finance, so there is no ordering to explain.

What review counts mean here. Where a firm has enough verified reviews to be worth citing, we cite the number and the date. Where it does not, as with System Six, we say so and do not cite one. A review count measures how many clients wrote something down. It does not measure technical quality.

Paid listings. Listing on Sam's List is free, and so is being named in this article. The firm written up here is a paid featured member of Sam's List, which is why it is written up here.
