Cash Flow Headache Guide (PDF)

The eight cash-flow mistakes that quietly drain trades businesses:

  • Slow invoicing

  • Poor Expense Tracking

  • Seasonality

  • Paying vendors too fast

  • Relying on financing

  • No tax reserve

  • Inaccurate job costing and margins

  • No forecast

The exact fix for each in a PDF field guide you can act on this week.

Run the Numbers

Your techs cost more than their wage, and a job can look profitable while quietly losing money. Run yours through these two, then use the spreadsheet to give every dollar a job.

Labor Burden Calculator

Your techs cost far more than their hourly wage. This finds the true loaded cost per billable hour, then the rate you need to charge to hit your target margin.

Company defaults

Field technicians (field techs only, no office staff or owner)

NameWage ($/hr)Hours/wk

Annual overhead (costs that exist with zero field techs: office staff, owner salary, rent, software, marketing, insurance)

Estimate only. Uses FICA 7.65% and FUTA 0.6% federal plus your state's typical rate. Confirm your actual workers' comp and state rates against your policy and pay stubs.

Job Costing & Margin Calculator

Enter what a job actually costs and what you charged. See your true gross margin, checked against healthy trades benchmarks. Pull your loaded labor rate from the calculator above.

Profit First Allocation

A scriptless Profit First allocation spreadsheet:

  • Set your percentages once

  • Enter each deposit

  • And it tells you exactly how much to move to Owner's Pay, Profit, Taxes, and Operating.

Set Up Clean Books

Garbage in, garbage out. Misclassified expenses give you wrong margins; wrong COGS gives you wrong pricing. Clean books start with three things:

  • The right account structure

  • Consistent categorization

  • A monthly close that verifies it all.

How a trades chart of accounts is numbered
RangeWhat lives thereWhy it matters for trades
1000sBank & assetsSeparate Owner's Pay, Tax, and Payroll accounts make Profit First real. Undeposited Funds lives here; the graveyard where trades cash goes missing.
2000sLiabilitiesPayroll liabilities broken out, sales tax payable, and vehicle notes tracked by loan so debt service is visible.
3000sEquityOwner contributions and distributions kept clean and separate.
4000sIncomeSplit by trade and service line (HVAC, plumbing, electrical) so you can see revenue mix at a glance.
5000sCost of goods soldThe one most trades books get wrong: direct labor belongs in COGS, split into wages, payroll taxes, workers' comp, and benefits so your gross margin is actually true.
6000sOverhead expensesOffice wages, vehicles, marketing, and shop kept out of COGS so overhead percent means something. EBITDA add-backs are tagged for clean valuation.
7000s / 8000sOther income & expenseInterest, rebates, reconciliation discrepancies, fraud and theft kept below the operating line so they do not distort your real numbers.
9000sContra / reversingReversing entries that zero out monthly, so owner draws and loan principal never masquerade as expenses.

This is the structure behind clean margins, accurate labor efficiency, and a valuation buyers trust. Download the full account-by-account template below and use it as your starting point.

Month-End Close Checklist

Phase 1 — Prep & Capture

Don't start a close on incomplete data.

  • Pull all bank, credit card, and loan statements for the period
  • Capture all receipts and bills in Dext/HubDoc and match to QBO
  • Process payroll and post the payroll journal for the period
  • Confirm beginning balances match last month's ending balances

Phase 2 — Categorize & Clean

  • Ensure all bank feed categorization is complete in QBO
  • Match inter-account transfers so Profit First moves aren't doubled as income or expense
  • Clear all uncategorized transactions
  • Confirm every transaction has a payee
  • Clear and match Undeposited Funds. This is the number-one place trades cash goes missing
  • Review and empty "Uncategorized" & "Ask My Accountant" accounts

Phase 3 — Reconcile

  • Reconcile all bank accounts and credit cards
  • Reconcile loans and notes to the lender statement
  • Reconcile sales tax payable and payroll clearing accounts
  • Reconcile FSM sales to revenue, and FSM payments to A/R. Close the FSM (ServiceTitan, Housecall Pro, Jobber) period once reconciliation is complete
  • Drive all clearing and suspense accounts to zero

Phase 4 — Adjusting Entries

  • Post inventory journal entries
  • Post the month's depreciation entryPro help
  • Amortize prepaid expensesPro help
  • Review owner's equity to ensure draws and contributions are booked right with no expenses miscoded to equity

Phase 5 — Compliance

  • Review vendor payments, confirm W-9s on file, flag vendors nearing the 1099 threshold
  • Accrue sales and use tax correctlyPro help

Phase 6 — Review & Report

  • Check P&L and balance sheet variance against budget
  • Compare month-over-month and same-month-last-year to catch creep
  • Scan for negative or abnormal balances
  • Review A/R and A/P aging past 30, 60, and 90 days
  • Sanity-check gross margin by job type
  • Update the KPI scorecard (net, gross, labor efficiency, overhead %, AR/AP days)
  • Review the cash flow statement

Phase 7 — Finalize

The control step most DIY closes skip.

  • Attach supporting documents to entries
  • Set the closing date and password in QBO so the period locks
  • Deliver the management report to the owner

The Pro help steps like depreciation, prepaids, and use-tax accrual, are easy to check off and still get wrong. If any of those are fuzzy, that's exactly what a free Profit Leak Audit is for. Download the working checklist below and run your close against it every month.

Can You Categorize From the Bank Feed?

This is what your books actually show you: a vendor and an amount, nothing else. Sometimes that is enough. Often it is a trap, and the only honest move is to pull the receipt. Can you tell which is which?

Card 1 of 12Score: 0
Bank feed

How would you categorize this?

Rule 1: categorize by purpose, not vendor name

The same vendor can land in five different accounts. Home Depot could be job materials, shop supplies, a tool, a company-party expense, or an owner's personal purchase. The vendor name tells you nothing; why you bought it tells you everything.

Rule 2: the bank feed can only be trusted for single-purpose vendors

A vendor that sells one thing such as ServiceTitan, a payroll processor, Google Workspace, your bookkeeper, is usually safe to code straight from the feed, because the name is the category. A general store like Home Depot, Amazon, Costco, Menards, is not: the feed tells you where you shopped, never why. Two identical "AMAZON $214.00" lines can be job materials on one day and office paper the next, and the feed cannot tell them apart. For those, you pull the receipt every time.
And a bank line is not proof. Under an IRS audit, a bank or credit card statement is not substantiation for a deduction; the receipt is. So the rule is not just "pull the receipt when the vendor is ambiguous," it is keep every receipt, period. Coding from the feed is about which ones you can categorize confidently; the paperwork you keep regardless.

The call that makes or breaks your margin: COGS vs. overhead

Ask one question: would this cost exist if you had not run this specific job? If yes, it is a direct cost of that job, a COGS. If it would be there whether or not the truck rolled, it is overhead. Materials on a job are COGS; shop consumables are overhead. Field-tech wages are COGS; office wages are overhead. Get this line right and your gross margin is finally real.

Where does it go? Common trades feed lines

A starting map. Your chart of accounts sets the exact account names.
PurchaseWhere it goes
Equipment & materials installed on a jobCOGS – Job Materials
Permits pulled for a jobCOGS – Permits
Subcontractor on a jobCOGS – Subcontractor
Field technician wages, taxes, workers' compCOGS – Direct Labor
Merchant & consumer-financing feesCOGS – Merchant / Financing Fees
Shop rags, gloves, nitrogen, consumablesCOGS – Shop Stock
A tool used across many jobsSmall Tools & Equipment (overhead)
Truck fuel, repairs, insuranceVehicle & Truck Expense (overhead)
Office paper, ink, postageOffice Supplies (overhead)
Dispatch / accounting / office softwareSoftware (overhead)
Payroll processing fees (e.g. "ADP FEES")Payroll Processing Fees (overhead) — not a payroll liability
Google Ads, Angi, direct mail, signageAdvertising & Marketing (overhead)

Note: we book merchant and consumer-financing fees to COGS, not bank charges because they are a direct cost of getting paid on a job, and keeping them in COGS makes your true job margin honest.

Three things that are NOT expenses Pro help

Loan principal. Only the interest is an expense. Principal pays down a liability. Book the whole payment as an expense and a good month can look like a loss.
Owner's draws. Money you take out for yourself is equity, not an expense; even when it is bought on the business card at a business vendor.
Buying a truck or other big asset. That is a fixed asset on the balance sheet, expensed over time through depreciation, not a one-month hit to your P&L.

These three are the most common way a profitable trades business looks broke on paper. If any are fuzzy, that is exactly what a free Profit Leak Audit untangles.

Know Your Numbers: Trades Benchmarks

You don't need to guess what healthy looks like. These are the numbers we check when we review a trades business in the $300K-$8M range. Start with the benchmarks, then carve out the best targets for your mix.

Financial benchmarks for HVAC, plumbing & electrical ($300K-$8M)
MetricHealthy targetWhy it matters
Net profit margin8-18%+Under 8% and you are carrying the risk for very little reward.
Gross profit margin (blended)45-65%Below 40% usually means pricing, labor tracking, or materials are off. Check it by job type.
Revenue per technician$300K+/yrBelow $250K/tech points to low pricing, poor dispatching, or idle time.
Overhead % of revenueunder 30% (best under 15%)High overhead means seasonal cash strain and thin net margin.
A/R over 30 daysunder 10% of A/ROld invoices delay vendor payments and choke cash flow.
Cash runway2-3 monthsCash, not sales, keeps you alive through slow seasons.
A/R daysunder 30 (under 15 residential)Slow collections make you the bank and squeeze payroll.
A/P days25-30Use your vendor terms; paying too early chokes cash.
Owner's drawsunder 75-80% of net profitDraw past profit and you pull equity out of the business.
Debt serviceunder 10-15% of revenueAbove that, loan payments start starving operations.
Marketing ROI400%+If you are not tracking it, you do not know which sources to fund.
Field labor % of revenue25-35%Too high is bloated payroll; too low often means underpaying or missing support.

Frequently Asked Questions

What is a labor burden rate for an HVAC, plumbing, or electrical technician?

Labor burden is the true hourly cost of a field technician once you add payroll taxes, workers' comp, health insurance, retirement, and other benefits on top of their wage, then divide by the hours they can actually bill after holidays, PTO, training, and shop time. For most trades techs the loaded cost runs roughly 1.5 to 1.7 times the nominal hourly wage, so a technician paid $35 an hour often costs $50 to $60 an hour of billable time.

What is a healthy net profit margin for a trades business?

For HVAC, plumbing, and electrical businesses in the $300K to $8M range, a net profit margin of 8 to 18 percent or higher is a healthy target. Under 8 percent usually means you are carrying most of the risk for very little reward, and the fix is typically in pricing, job efficiency, or overhead.

How do I know if my books are costing me money?

The most common signs are not knowing your margin by job type, paying vendors before collecting from customers, vague catch-all expense categories, skipping your own pay in slow months, and making spending decisions off your bank balance instead of what is already committed. Our free What's Broken in Your Books diagnostic and Cash Flow Leak Scorecard on this page walk you through the specific red flags.
