IN-HOUSE BOOKKEEPER? THREE WAYS TO COVER THE WORK.

QUICK ANSWER

An in-house bookkeeper is the right answer when there is enough daily work, the person is good, and someone senior reviews what they do. The risks are single point of failure, nobody checking the work and no job cost structure behind the coding. The alternatives are an outsourced bookkeeping team, a controller-led outsourced finance firm, or a hybrid with a part-time in-house person.

The problem with a lone in-house bookkeeper is rarely the person. It is that nobody is checking the work, the knowledge lives in one head, and a vacation or a resignation stops the books. A bookkeeper also usually works inside the structure they were given. If the job cost codes do not match the estimate, the bookkeeper codes faithfully to the wrong structure. The decision is how much daily presence you need, who reviews the work, and what happens when they are out. The right option depends on those three answers.

WHEN KEEP THE IN-HOUSE BOOKKEEPER IS RIGHT

WHEN THERE IS DAILY WORK AND REVIEW.

A good in-house bookkeeper who is busy most of the week, who knows your vendors and your jobs, and whose work is reviewed by someone senior is hard to beat. They are in the building, they answer a question in a minute, and they know the field crew.

It stops working when nobody reviews the work, when the person is the only one who knows how it works, or when the volume falls short of a full week and you are paying for idle hours.

WHEN OUTSOURCED BOOKKEEPING IS RIGHT

WHEN YOU WANT COVERAGE AND CONTINUITY.

An outsourced team covers for vacations and resignations, so the books do not stop. Several people see the work, which catches mistakes one person would miss, and you pay for the work and not for a seat.

The limit is that a bookkeeping service often codes to your structure without questioning it, and it is not in the building. If the structure is wrong, you get clean, reconciled and wrong reports faster.

WHEN OUTSOURCED FINANCE WITH A CONTROLLER IS RIGHT

WHEN THE RECORD AND THE STRUCTURE BOTH NEED WORK.

This option bundles the bookkeeping with the job cost structure, a reviewed close and a monthly meeting. Someone senior owns whether the numbers are right and what they mean, and the bookkeeping is done to a structure designed against your estimating. That is the model SPM runs.

It costs more than bookkeeping alone, because it does more. If your books are in good condition and you only need them kept current, it may be more than you need.

THE ANSWER

WHERE WE COME OUT.

Keep the in-house bookkeeper if the person is good, the work fills the week and someone senior reviews the close. Do not replace someone who is doing the job well because of a general worry.

Use outsourced bookkeeping if your problem is coverage and continuity and your job cost structure is already sound.

Use outsourced finance with a controller if you are not sure the structure is right, nobody reviews the close, and you would like to stop being the person who checks. Whichever you choose, ask what happens the week your bookkeeper is out, because that tells you how fragile the setup is.

COMMON QUESTIONS

FREQUENTLY ASKED.

Replace the setup when nobody reviews the work, the person is the only one who knows the system, or the books keep falling behind. Do not replace a good person only because you have a vague worry. Add review around them first.

It can be, if the firm has construction experience and works inside a structure that matches your estimating. The risk is clean books on the wrong cost codes. Ask how they code to jobs and phases.

A bookkeeper keeps the record. They do not usually design the job cost structure, review WIP or build a forecast. If you need those, the function is above bookkeeping, and replacing the bookkeeper will not supply it.
