Marine Service Controller

Controller Services for Marine Service Companies


A marine service shop lives on billable hours and parts margin, and both slip away quietly when the yard is slammed in summer and dead in winter. A controller keeps the close reviewed and the utilization honest — so you know your real effective labor rate before the slow season does the math for you.

Billable hours and parts margin need review

Your labor is only worth what you bill, and the gap between hours paid and hours billed — techs waiting on parts, warranty work, comebacks — is where profit silently goes. Parts carry their own margin that erodes through markup drift and shrink. A controller reviews utilization and parts margin each close, so the effective labor rate is a number you know, not one you discover in the off-season.

Reconciliation keeps it real. Work-order and shop-management data, deposits, and the books should agree, and seasonal AR can't be left to age. A controller ties it all together month to month.

What a controller adds over a bookkeeper

A bookkeeper records the transactions. A controller makes them right and turns them into a reviewed package: effective-rate and utilization KPIs, parts-margin review, job profitability, and a close that reads accurately through the seasonal swing.

With multiple techs or a growing shop, standardized reporting shows which techs and which work actually pay — not one blended number that smooths a good month and a bad one together.

How Kaizen runs it

We sit on top of your bookkeeping — ours or yours — and run a documented monthly close on the same date every month. Work-order revenue, parts, and deposits get reconciled to the accounting so the systems agree.

Then the improvement part we're named for: each close the utilization reporting tightens and the review catches more before it reaches you. Controller judgment without the salary or the eventual resignation.

Straight answers

We have a bookkeeper. Why a controller?

A bookkeeper records; a controller reviews utilization and parts margin, reconciles the work-order system, and produces a close you can manage on. Many shops keep their bookkeeper and add us for oversight.

Can you show our real effective labor rate?

Yes — billed hours against paid hours, net of warranty and comebacks, reviewed each close. It's often a sobering first number and the fastest lever on profit.

Do you reconcile our shop-management system?

Yes — work orders, parts, and deposits get tied to the accounting and the bank so nothing hides between systems.

One- or two-tech shop. Overkill?

Probably, and we'll be honest. A good bookkeeper and a KPI report may be enough until you have several techs or bays to compare.
