Contractor Bookkeeping Services: What Job Costing Should a Monthly Quote Include?
Compare contractor bookkeeping quotes using a real-world bidding scenario. See how materials, crew hours and callbacks change job margin, and what to ask before you hire.
An HVAC installer closes a $12,000 replacement job on Friday. The customer pays, the supplier bill clears, and the bank balance looks healthy. On Monday the estimator wants to bid a similar job. What did the first one actually earn? If the books can only show what the whole company spent last month, the estimator is still guessing. That is a good reason to ask about job costing when you compare contractor bookkeeping services.
A monthly quote should tell you who assigns costs to each job, how anyone checks the assignments, what happens to missing information, and what report you receive before your next bid. Here is a way to test a proposal using a job you already understand. It works for a small HVAC, roofing or remodeling business that uses QuickBooks and wants more from month-end than a bank reconciliation.
Start the interview with one finished job
Choose a job that involved a material purchase, at least one crew visit, and an invoice. Put the estimate, approved changes, supplier invoices, crew hours and customer invoice in date order. Give the prospective bookkeeper a redacted summary. Ask them to describe what they could tell you from that packet and where they would need the foreman’s help. A useful answer identifies specific gaps. For example, the supplier invoice might list two delivery addresses even though only one job number appears at the top.
Listen for one question in particular. Who in your business knows where the materials went? A person looking at a bank feed can see that you spent $860 at a supply house. Your lead installer might be the only person who knows that $620 went to the replacement job and $240 went to a service call. A proposal needs a practical way to get that answer while the crew still remembers.
A $12,000 job that looked better on paper
Suppose the approved selling price is $12,000. The estimate allowed $4,000 for equipment and materials, $2,400 for direct labor and $800 for a subcontractor. Estimated direct cost is $7,200. Subtract that from the price and the estimated gross profit is $4,800, or 40% of the selling price. These are illustrative figures for comparing bids, before company overhead.
The final supplier invoices total $4,350. Crew time valued on the same basis as the estimate comes to $2,700, and the subcontractor sends a $950 bill. Add a return trip costing $300 in direct labor that was missing from the first set of time records. Actual direct cost becomes $8,300. On the same $12,000 price, the job earned $3,700 before overhead, or about 30.8%. The $1,100 difference has four identifiable sources. A monthly report that stops at the original estimate leaves the next bid exposed to the same mistake.
The owner can now act on a specific number. Materials ran $350 over estimate. The initial crew hours cost $300 more, the subcontractor cost $150 more, and the callback cost another $300. Ask which of those items a provider would have spotted before the job was closed and how you would learn about an invoice that arrived later. The answer helps you decide whether monthly reporting is frequent enough for the way you bid.
What to put in a contractor bookkeeping quote
Job names and source records. Agree on a job identifier that the office, crew lead and supplier can all recognize. Ask who creates it when you accept a bid and who adds it to purchase orders and time records. Give the provider a real example where two jobs share the same customer or street. If those get merged, both margins can be wrong even when the company totals are right.
Labor and callbacks. Decide which cost components the owner wants in a job report, who supplies the figures, and how estimated hours will be compared with actual hours. Ask how a callback after the original invoice will appear. If payroll processing or importing timesheets is a separate service, the written quote should say who does it and what the bookkeeper receives.
Unassigned transactions. Ask to see an example of the questions the office receives. A useful list gives the vendor, date, amount, possible jobs and a person responsible for the answer. Pick a day each week for someone to clear the list. Agree what happens to unresolved items at month-end so a provisional margin is clearly marked when you read it.
Deliverables and timing. Request a sample with made-up numbers. Look for the approved job price, direct costs by group, gross profit, unresolved items and the reporting date. Ask whether you receive this for every active job, only completed jobs, or a selection. A contractor bidding weekly may value a short exceptions report between monthly closes more than a polished year-end summary.
Compare two proposals on the same job
Imagine one proposal includes reconciling your bank and credit cards, recording bills and delivering a company profit and loss statement. Another also identifies job-coded transactions, follows up on missing crew hours and produces a job summary. Both can be sensible purchases. If your office already does the job allocation well, you may only need the first. If your next bid depends on knowing installation labor by job, ask the first provider to price that extra work before comparing monthly fees.
Check the software assumptions as well. Intuit documents its native comparison of project cost estimates with actuals for specific QuickBooks products. Ask the provider to show how the agreed report would be produced with your current subscription. A spreadsheet tied back to the books can be enough for a one-crew business. Include any software upgrade, connector or recurring reporting charge in the comparison. Read Intuit’s guide to project estimates and actual costs.
Separate the first month from the monthly fee
Old job records can take time to reconstruct. Ask the provider to specify the first month they will cover, the jobs they can reasonably rebuild, and the opening balances they need from you. For a job already finished with incomplete time records, an honest estimate may be the best available figure. Ask that it be labeled. You can then put your effort into making current jobs reliable without paying to chase paperwork that no longer exists.
LiveFixPro lists monthly bookkeeping at $499 per month. The scope is confirmed in writing. Describe the number of crews, jobs, accounts and reports you need before assuming a particular job-costing workflow is included. If the historical books also need attention, ask for that work to be quoted separately. You can compare LiveFixPro’s bookkeeping plans before the conversation.
What to bring to a free consultation
Bring one finished estimate, a list of active jobs and a redacted example of the report you use today. Write down one decision you want to make sooner. It might be whether to change your equipment allowance, price a second visit into the next bid, or ask a subcontractor for a firmer quote. That decision gives both sides a concrete test for the proposed service.
