Bookkeeping for Contractors & Trades

Job costing, draws, subs, and 1099s — handled by someone who spent years running construction and roofing operations, not a bookkeeper learning your industry from a textbook. We keep your books organized job by job so you know what you actually made on every project.

Books that work the way construction actually works

Most bookkeepers treat a construction company like any other small business: money in, money out, one big P&L. That's how contractors end up profitable on paper and broke in the bank account. AJM Consulting builds your books around the thing that actually matters — the job.

Our founder spent years running construction and roofing operations before starting this practice — managing crews, pricing bids, chasing draws, and watching job costs eat margins in real time. When you say "retainage," "change order," or "the sub still hasn't sent his W-9," we don't need it explained. That operating experience is the difference between a bookkeeper who codes your transactions and one who understands why the job, not the month, is the unit that matters in your business.

The core of what we do is job costing: tracking the income and every cost — labor, materials, subcontractors, equipment, permits — against the specific job it belongs to. Company-wide totals can look healthy while two or three jobs quietly bleed money. When costs land on the right job, you can finally see which projects, which job types, and which customers made you money, and you can carry that knowledge into your next bid. If you want the full picture of how it works, we wrote a deeper guide on job costing for contractors.

We also keep the money side of long jobs sane. Progress billing and draw schedules get tracked so you always know what's been billed, what's been collected, and what's still owed on every open project. Front-loaded deposits get recorded so they don't masquerade as profit before the work is done, and retainage or holdbacks are tracked simply — so the five or ten percent sitting with the GC doesn't just vanish from your radar until you wonder why cash is tight.

What's included

QuickBooks for Construction

Overhead vs. Job Costs

Shop rent, insurance, and office costs separated from job costs so your margins are real, not blended.

Overhead, cash flow, and the numbers between jobs

One of the most common problems we see in contractor books is overhead blended into job costs — or worse, job costs blended into overhead. Your shop rent, general liability insurance, office costs, and the truck that serves every job are not the same thing as the lumber package for the Miller job, and your books should say so. When overhead is separated cleanly, you can see your true gross margin per job and know how much every job needs to contribute just to keep the lights on.

Then there's cash flow, which in construction has its own physics. Long jobs mean money arrives in lumps — a deposit up front, draws along the way, a final payment that may trail the punch list by weeks — while payroll, materials, and fuel go out every single week. We keep your cash picture current across all open jobs, so a big deposit reads as what it is: work you still owe, not money you get to spend twice.

We also make sure the everyday costs that nickel-and-dime a trade business — equipment, repairs, fuel, vehicle costs, small tools — are captured consistently. Individually they're small; over a year they're often the difference between the margin you think you're making and the one you actually are.

Behind on your books? Start with a catch-up cleanup.

Plenty of contractors come to us mid-season with months of unreconciled accounts, a shoebox of receipts behind the truck seat, and a QuickBooks file that hasn't matched the bank since spring. No judgment — you were building. We'll catch the books up, sort transactions onto the right jobs where the trail still exists, reconcile every account, and put a simple monthly rhythm in place so it doesn't pile up again. If you're not sure whether you need a cleanup or ongoing monthly work, our bookkeeping services page lays out how both engagements work.

Why us

A bookkeeper who's been on the job site

Most bookkeepers who advertise "construction experience" mean they once had a contractor as a client. Ours is different: before AJM Consulting existed, our founder ran construction and roofing operations — hiring and scheduling crews, pricing bids and living with the ones that were wrong, managing draw schedules, and watching what materials, fuel, and callbacks really do to a margin. The books we build for contractors come from that side of the table.

Practically, that means your chart of accounts reflects how a job actually flows, your reports answer the question you're really asking — did that job make money, and why? — and conversations with your bookkeeper don't start with a vocabulary lesson. You work directly with a consultant in Kalispell who picks up the phone, not a ticket queue.

Questions

Contractor bookkeeping FAQs

Do you actually understand construction, or is this bookkeeping-firm construction?
Our founder spent years running construction and roofing operations — managing crews, bidding work, scheduling draws, and living with job costs — before ever touching a client's books. So when you talk about a change order, a draw schedule, or a sub who hasn't sent a W-9, you're not explaining your industry to your bookkeeper. That operating background shapes how we set up and run every contractor's books.
What is job costing and why does it matter for my business?
Job costing means tracking the income and the costs of each job separately — labor, materials, subs, equipment, permits — instead of lumping everything into one company-wide pile. It matters because your overall P&L can look fine while individual jobs quietly lose money. With real job costing you can see which jobs, job types, and customers actually made money, and use that to bid the next one better.
Can you set up QuickBooks Online for job costing?
Yes. We set up QuickBooks Online with a construction-friendly chart of accounts and use its projects and job-tracking features so income and costs land on the right job automatically. If you already have QuickBooks but everything is dumped into a few generic accounts, we can restructure it without losing your history.
How do you handle subcontractors and 1099s?
We track every subcontractor payment against the right job as the year goes along, keep W-9s organized, and make sure sub costs are separated from employee labor. When January comes, 1099 filing is a routine step instead of a scramble through twelve months of bank statements trying to remember who you paid for what.
What does contractor bookkeeping cost?
A flat monthly fee — never hourly. The price depends on your transaction volume, how many jobs you run at once, how many accounts we reconcile, and whether you need payroll or 1099 support in the scope. We scope it after a free 30-minute consultation, so you know the number up front and it doesn't change when you have a busy month.
Do you work with contractors and trades outside Kalispell?
Yes. We're based in Kalispell and serve the Flathead Valley in person — Whitefish, Columbia Falls, Bigfork, and the surrounding area — and contractors across the rest of Montana remotely. Since the work runs through QuickBooks Online and secure cloud tools, your books get the same attention whether you're across town or across the state.
