Before you hire a controller, confirm five things: your close is running late, your job or product margins are unreliable, cash keeps surprising you, you're the only real oversight on the books, and you can budget either $100k+/year in-house or $3,000–$7,500/month fractional. If most of those are true, you're ready.
Key takeaways
- The readiness test is symptoms, not revenue: a late close, unreliable margins, cash surprises, and being the only oversight all point to the same thing, most often between $2M and $10M.
- A full-time controller runs roughly $100k+/year in salary alone (closer to $150k–$180k fully loaded); a fractional controller runs about $3,000–$7,500/month. Pick by hours needed, not job title.
- Most owners searching "hiring a controller checklist" find interview-question lists. The harder question is whether you are ready and set up for the role to succeed. That's what this checklist covers.
How do I know if my business is ready to hire a controller?
You're ready when the books have stopped keeping up with the decisions you need to make. A bookkeeper records what happened. A controller owns accuracy, the monthly close, internal controls, and reporting you can actually run the business on. When you keep asking questions your books can't answer, that gap is the signal.
Run through these readiness triggers. If three or more are true, you've likely outgrown a bookkeeper-only setup (see signs your SMB has outgrown its bookkeeper):
- Your month-end close is late or unpredictable. If you're getting last month's numbers 15 to 20 days into the next month, every decision you make is three weeks behind. A healthy close lands in about 5 to 7 days.
- Your margins are unreliable. You can see total profit but not which jobs, products, or service lines actually make money. For contractors and trades, that usually shows up as job costing you don't trust.
- Cash keeps surprising you. The P&L shows profit but the bank account is tight, and you're managing timing by feel rather than a forecast.
- You are the only real oversight. One person enters everything and nobody checks it, or you're personally the backstop reviewing the books at night.
- Leadership is asking what-if questions no one can model. Pricing changes, a new hire, a second location, and the answer is a guess.
None of this means your bookkeeper failed. The role simply tops out. Recording history and owning the numbers are two different jobs.
What should a controller be responsible for?
Write the scope before you write the job post. A controller who owns a clear list beats a great résumé plugged into a vague role. At minimum, the person or firm you hire should own:
- The monthly close: a real calendar with a 5-to-7-day target, not a "whenever it's done" close.
- Reconciliations and controls: bank, credit card, AR, and AP tied out every month, with a second set of eyes on the money (maker-checker).
- The chart of accounts: structured so it actually reveals COGS and margin instead of hiding them.
- Reporting that drives decisions: a P&L, balance sheet, and cash-flow view, plus the 5 to 8 numbers you should see monthly.
- Job- or product-level margin: the profitability cut your business runs on. For construction and trades, that means WIP schedules, over/under-billing, and retainage.
- AR and AP discipline: invoicing on time, collections tracked, DSO trending down.
Note what is not on that list: taxes and attest work. A controller keeps the books clean and forward-looking. Your CPA files and signs. Walden works the same way. We do the controller and CFO work, and refer every bit of tax and attest back to your CPA.
What should I have in place before a controller starts?
Get these ready so the first 30 days go to real work instead of hunting for logins:
- Access to your accounting system with an admin or accountant seat, not a shared password.
- Bank, credit card, payroll, and lender statements for at least the last full year.
- A current chart of accounts and a list of open AR and AP.
- Any existing reports or spreadsheets you use to run the business, even the messy ones.
- A short list of the decisions you can't currently make because the numbers aren't there. This tells the controller what to fix first.
If your books are behind or you've had several bookkeepers over the years, say so up front. Cleanup is common and it's cheaper to name it than to discover it in month two.
Should I hire a full-time or fractional controller?
Choose by how many hours of controller-level work you actually have, not by how established you want to look. Most owner-operated businesses between $2M and $10M need 10 to 30 hours a month of controller work, not 160. That's the range where a fractional controller usually wins on both cost and quality.
| Option | Typical cost | Best for | Tradeoff |
|---|---|---|---|
| Better bookkeeper | $300–$1,500/mo (market range) | Clean records only; no reporting or controls need yet | Can't own close, margin, or forecasting |
| Fractional controller | $3,000–$7,500/mo (market range) | $2M–$10M owners needing 10–30 hrs/mo of real controller work | Not sitting in your office full-time |
| Full-time controller | $100k+/yr salary; ~$150k–$180k+ fully loaded | Larger or complex orgs with 30+ hrs/wk of work | Recruiting cost, turnover risk, benching an expensive hire |
Cost figures are directional 2025–2026 market ranges aggregated across providers and salary data; verify current quotes before budgeting.
The number owners underestimate is the fully loaded cost of the full-time hire. A $120k base is rarely $120k. Add benefits, payroll taxes, software, and overhead at roughly 1.4 to 1.8 times base, plus a recruiting fee of 20% to 30% of first-year salary, and you're near $180k before the first close. Below the point where you have a full week of controller work every week, that math rarely holds. For the detailed side-by-side, see fractional controller vs. full-time.
The honest downside of fractional: the person isn't only yours. A firm juggling 8 to 10 clients with a junior on your file is a real risk. Ask directly who does the work and how many accounts they carry. At Walden the answer is that the founder delivers the work, which is why we cap how many clients we take.
How much does it cost to hire a controller, and what do you get back?
Plan for one of two budgets: roughly $100k+/year for a full-time controller (closer to $150k–$180k loaded), or about $3,000–$7,500/month for a fractional controller at 10 to 30 hours a month. Hourly fractional rates run about $125–$250 (higher in major metros). Those are the market ranges; the better question is what the role returns.
The return shows up as decisions you can finally make on time: which jobs to stop taking, which customers pay slow, where margin is leaking. A close that moves from 20 days to 7 means you're steering on this month's numbers instead of last month's.
Framed against the fee, the goal we work toward is at least 7x our fee in measurable value within the first 90 days. That's the target we aim for, not a guarantee. The way to see the number for your own business is to have someone actually look at the books.
What questions should I ask before hiring a controller?
Ask these before you sign, whether you're interviewing a person or a firm:
- Who actually does the work on my account, and how many clients do they carry? You're checking for a senior name on the pitch and a junior on the file.
- What does your month-end close process and timeline look like? Listen for a real calendar and a 5-to-7-day target.
- How will you handle my job or product margin specifically? For trades, ask about WIP and over/under-billing by name.
- What controls will you put in place so one person isn't unchecked? Maker-checker separation is the answer you want.
- What stays with my CPA? The right answer is all tax and attest work.
- What will you fix in the first 30, 60, and 90 days? A ready controller can tell you.
Red flags: vague answers on who does the work, no defined close process, a promise to also handle your taxes (scope creep into CPA territory), no interest in your existing systems, or pressure to sign a long contract before diagnosing anything.
Do I need a controller or just a better bookkeeper?
If your books are simply behind or messy but the questions you're asking are still "what did we spend," a stronger bookkeeper may be enough. If your questions have shifted to "which of these jobs actually made money, and will I make payroll in six weeks," that's controller work. The clearest tell is the calendar: a bookkeeper keeps the record, a controller closes the month on a deadline and hands you numbers you can decide on.
Walden does not do tax, attest, or compliance work and refers it back to your CPA. Stephen Wray delivers every engagement personally, which is why Walden caps how many clients it takes on.
