Marcus isn't one of our clients. He represents a lot of them.

For the purposes of this article, Marcus runs a landscaping and grounds-maintenance company in the South Sound. He and his wife started it about eight years ago and are at roughly $850,000 in annual revenue, with four crews and weekly payroll. All dollar figures and business details in this composite are illustrative, drawn from patterns we see across Washington service businesses, not from any single client.

Here is the short version of what changed when he moved to monthly outsourced accounting: the catch-up revealed about $18,000 in expenses that had never been recorded or had been put in the wrong places. His B&O classification got corrected. And the April tax bill stopped being a surprise.

What the before state looked like

Marcus was doing the QuickBooks himself, on Sunday evenings. Enter the transactions, reconcile the bank statement at month-end when he had time, which was not always. Every February he sent the file to a tax preparer, who filed on April 15 and sent an invoice. That was the year.

He was also handling Washington B&O himself, filing quarterly. He had been doing this for three years.

The arrangement felt functional. He knew roughly where the cash was. He had not had a problem yet.

What he did not know: how much time the Sunday-evening work was actually costing him (both in hours and in the mistakes that compound quietly over months), and that his B&O classification had been wrong since day one.

The trigger

In March, his tax preparer called with the estimate. About $14,200 in federal taxes due in six weeks. Marcus had planned for maybe half that.

The money was there, but barely. He had two truck lease payments coming in April that he had been counting on for months. He moved the equipment purchases he had been planning and absorbed the hit. Not a disaster. Just a number that arrived after the window to do anything about it had closed.

That pattern is the most common thing we hear from WA service businesses that call us. Revenue up, expenses managed, books sort of current, but no visibility into the year until it is almost over. By the time you know what you owe in March, it is March.

The first 90 days

We started with a catch-up. Three months of transactions, plus a full chart-of-accounts review.

Some expenses had been put in catch-all categories that would make year-end reporting harder than it needed to be. A recurring software subscription for crew scheduling had never been recorded. A handful of tool purchases had run through his personal card and were not on the books at all.

By the end of the catch-up, we had identified about $18,000 in expenses that were either unrecorded, miscategorized, or missing from the business records. To be clear: that figure is illustrative and reflects what we typically see in a service business that has managed its own books for a few years. It is not a guaranteed result, and the number varies significantly depending on the business and how the books have been kept.

The B&O situation was a separate problem. Washington's business and occupation tax has different classifications based on what you do and who you serve, and getting the classification wrong is one of the most common issues we find in WA service business books. Marcus had been filing, which put him ahead of some clients, but the classification did not match his type of work. We helped him get current. He was not yet in a penalty situation, though it was getting close. For a more detailed explanation of how B&O classification errors accumulate in service businesses, we covered the mechanics in this article.

The catch-up itself took about three weeks. He had to pull some bank statements and send over a few receipts. The back-and-forth was real, but it was not the months-long project he had worried about.

What changed month to month

Every month now, Marcus gets a financial close by the 15th. Cash on hand and payroll as a percent of revenue are the two numbers he checks first. If something looks unusual, we flag it in the same update. It takes him about twenty minutes.

But the quarterly estimates are where the real shift showed up. Because we do them against actual year-to-date numbers, Marcus knew by October what his Q4 looked like. He moved two equipment purchases into late December, which affected the year-end picture in a way that worked in his favor. He made that call in October, when there was time to make it. Not in March, when there is not.

He has not had an April surprise since the first year we worked together.

The other thing that changed: the bookkeeping is not his problem anymore. He is not doing it on Sunday evenings. That time does not show up on a financial report, but it has a value.

What the change actually required from him

One thing worth saying plainly: switching to outsourced monthly accounting is not a passive arrangement. Marcus had to send documentation during onboarding. He needed to review the financials each month and respond when we flagged something. In the first few months, there were more questions than usual while we learned his business.

It got lighter over time. By month four, the monthly review was mostly a quick read. But the first 90 days required real participation from him. Owners who want to hand everything over and never look at a number again tend to run into friction with any accounting arrangement. This one included.

Who this does not work for

Outsourced monthly accounting is not the right answer for every WA service business.

If your revenue is under $500,000 and your books are reasonably current, a part-time bookkeeper and a competent annual tax preparer may be the honest answer for where you are right now. The monthly retainer only makes financial sense when the volume and complexity justify it. We say that on the first call, not after you have committed to anything.

If you need daily job costing, tracking labor and materials by project or contract as the work happens, that is a different service than what we provide. Some businesses need a part-time controller for that function. We do not fill that role. Our work is the monthly close, B&O, tax planning, and tax prep as one package, not services stacked on top of someone else's bookkeeping. Details are at /services/accounting/.

The pricing question

Marcus's business, at around $850,000 with four crews and weekly payroll, runs about $1,200 per month. That number varies by volume and complexity. Our pricing starts at $750 per month for smaller, simpler operations and goes up from there. The full breakdown is published openly at /pricing/ because we think you should be able to run the math before getting on a call.

Questions owners ask about this

How long does a bookkeeping catch-up take for a service business?

For a business with six to twelve months of backlog, we typically work through it in two to four weeks. Longer backlogs and missing records take more time. You will know the full scope and the cost before we touch a transaction.

Does outsourced monthly accounting include Washington B&O?

Yes. B&O is part of the monthly close for WA service businesses in our package. We handle the classification and filing. If your B&O has been mis-filed or unfiled, the catch-up is part of onboarding.

How is monthly outsourced accounting different from hiring a bookkeeper?

A bookkeeper records transactions. Monthly outsourced accounting includes the bookkeeping, bank reconciliation, financial close, B&O, tax planning, and prep, all in one package. The difference is between having the books current and knowing what they mean and what to do next.

What does this typically cost for a service business at $800,000 to $1,000,000 in revenue?

Our pricing starts at $750 per month and scales with volume and complexity. A service business in this revenue range, with employees and weekly payroll, typically falls between $1,000 and $1,500 per month. The full pricing detail is at caroandassociates.com/pricing so you can run the math before we talk.

Is outsourced monthly accounting the right answer for every Washington service business?

No. Under $500,000 in revenue, a part-time bookkeeper and an annual tax preparer may be the honest answer. If you need daily job costing by project or contract, that is a different service than what we do. We say this clearly on the first call, not after you have committed to anything.
