Engineering Firm Bookkeeping: Why Your WIP Schedule Beats Your Bank Balance
A WIP schedule reconciles earned revenue, billings, and costs on every project, exposing the over- and underbilling that a bank balance and company-wide P&L hide. This guide covers percentage-of-completion revenue recognition, job costing, and billable utilization benchmarks for engineering firms.
Pressure Washing Business Bookkeeping: Job Costing by the Square Foot, GPM-vs-PSI Depreciation, and the Two-Story Surcharge You're Skipping
A per-square-foot job costing system for pressure washing operators, with a two-story height factor (1.35x-1.50x), component-level equipment depreciation, and a chart of accounts that shows true gross margin per service line.
Virginia's New Wage Liability Law: What HB 238 Means for General Contractors After July 1, 2026
Virginia HB 238 makes general contractors automatically jointly and severally liable for wages owed to a subcontractor's employees on construction contracts entered on or after July 1, 2026 — regardless of knowledge, and even when sworn payroll certifications say wages were paid. Here is what changed and how to reduce the exposure with tighter contracts, verified payroll, and clean job-cost accounting.
Sign Shop Bookkeeping: Monthly Books vs. Year-End Cleanup
A sign shop bookkeeping guide covering monthly close, job-level costing for materials/labor/overhead, deposit accounting, sales tax on signage, and Section 179 equipment deductions for 2026.
Roofing Contractor Bookkeeping: The WIP Schedule That Tells You Whether Your Bank Balance Is Lying
A roofing WIP schedule ties revenue to work actually completed rather than to when you invoiced — percent complete equals costs to date divided by total estimated costs, and earned revenue equals percent complete times revised contract price. This guide walks a $192,000 TPO re-roof through the math, explains over- versus under-billing, retainage receivable and warranty accruals, and covers when Section 460 forces percentage-of-completion for tax (roughly $31 million in average gross receipts for 2026, or contracts running past two years).
Personal Chef and Private Catering Bookkeeping: Grocery COGS, the Home-Kitchen Deduction, and Per-Client Profitability
How personal chefs and private caterers separate client grocery COGS from household spending, claim the home-kitchen deduction under the exclusive-use test, and job-cost every booking — with target food-cost ranges of 28–38% for weekly meal prep and 25–35% for private dinners.
Cleaning Business Bookkeeping: Job Costing, Payroll, and Supply Inventory
A contract-level bookkeeping system for cleaning and janitorial businesses—job costing by contract, a payroll-to-revenue dial that says when you can hire, and a 10-minute supply inventory method—so you can bid with real numbers and spot losing contracts before they drag the quarter.
Ghostwriting Agency Bookkeeping: Pricing Per-Word, Retainer, and Flat-Fee Work Without Losing Your Margin
How ghostwriting agencies account for the three pricing models — per-word, monthly retainer, and flat-fee book projects — including deferred-revenue entries for retainers, milestone versus cost-to-cost recognition on a $36,000 book, a 150-to-275-hour cost sheet for a 60,000-word business book, and the 1099-NEC and W-9 rules that keep contractor writers correctly classified.
Camper Van Conversion Company Bookkeeping: Final-Stage Manufacturer Status, Chassis Inventory, and Progress Billing for Multi-Month Builds
A camper van conversion shop that installs living-space modules on incomplete chassis is a final-stage manufacturer, not a services business: the chassis is WIP inventory, certification costs are manufacturing overhead, and deposits stay contract liabilities until ASC 606 over-time recognition turns cost-to-cost progress into revenue.
Translation and Interpreter Agency Bookkeeping: Per-Word and Per-Session Job Costing, Freelance Linguist 1099s, and the Utilization Rate That Separates 5% From 20% Margins
How translation and interpreting agencies should cost jobs by billable versus payable words and door-to-door session time, pay freelance linguists and file 1099-NECs, track utilization and overhead, and reconcile multi-currency and retainer cash flow to hold 30-50% gross margins and 15-25% net.
Wedding DJ and Mobile Entertainment Bookkeeping: Deposits, Gear Depreciation, and Off-Season Cash Flow
How wedding DJs and mobile entertainers should classify booking deposits and retainers under cash versus accrual accounting, depreciate sound and lighting gear under Section 179 or MACRS, track revenue and cost per event, issue 1099-NECs for second DJs, and survive the off-season cash crunch when most revenue compresses into a few months.
Appliance Repair Bookkeeping: Per-Job Parts Costing, Truck Stock, and the Warranty vs. Retail Split That Decides Your Real Margin
Customer-pay appliance repair calls earn roughly $200 in profit versus about $75 for warranty calls, and parts carry 30-100% markup — books that track parts cost per job, truck stock as real inventory, and the warranty-retail mix reveal which calls actually make money.
