Cold Plunge and Sauna Recovery Studio Bookkeeping: Presales, Six-Figure Build-Outs, and the Utilization Math That Decides Your Margin
How to book a cold plunge and sauna recovery studio from presale to full capacity — founding-member cash held as deferred revenue under ASC 606, a $110,000–$250,000 build-out split between Section 179 equipment and 15-year qualified improvement property, and the three utilization KPIs (plunge occupancy, revenue per plunge-hour, churn by wait-time cohort) that show whether another chiller pays.
Section 45W Has Expired: What the Commercial Clean Vehicle Credit's Sunset Means for Small Fleets
The One Big Beautiful Bill Act ended the Section 45W Qualified Commercial Clean Vehicle Credit — the lesser of 15% of basis (30% for pure EVs) or incremental cost, capped at $7,500 under 14,000 lbs GVWR and $40,000 at or above — for vehicles acquired after September 30, 2025, along with the 30D and 25E credits. Only the Section 30C refueling-property credit survives, for property placed in service through June 30, 2026. Covers the acquisition-date and written-binding-contract tests that decide whether a vehicle you ordered still qualifies, how a fleet EV pencils out on total cost of ownership without federal money, and the Section 179, bonus depreciation, and per-VIN asset records that replace it.

Massachusetts Decouples from OBBBA: What R&D Expensing, Section 179, and Bonus Depreciation Changes Mean for Your Business
Massachusetts rejected four major OBBBA federal tax breaks — immediate R&D expensing, 100% bonus depreciation on qualified production property, the $2.5M Section 179 limit, and the EBITDA-based interest cap — and set a September 10, 2026 deadline to file amended 2025 state returns without interest charges.
Towing Company Bookkeeping: Tow Truck Depreciation, Impound Lot Revenue, and the Compliance Costs Most Owners Underprice
A tow truck over 14,000 lbs GVWR can often be fully expensed under Section 179 the year it's placed in service — but only if the depreciation schedule starts that year. How towing companies should separate tow, impound, and lien-sale revenue, reconcile lot logs monthly, and price compliance costs into every job.
Billboard and Outdoor Advertising Bookkeeping: Yield, Volume, and Why Your Ground Lease Is COGS
A bookkeeping guide for small billboard and out-of-home (OOH) operators — why yield and volume must be tracked separately, why ground leases belong in COGS tagged by board, how static and digital faces differ on depreciation and revenue recognition, and the five KPIs worth reviewing, including 85%+ utilization targets and a ~2.5-year payback benchmark on new digital builds.

How mobile pet groomers should book a $35,000–$80,000 grooming van — splitting chassis from buildout for depreciation and Section 179, building a five-component per-appointment cost model, and budgeting fuel and maintenance against the 76-cent 2026 IRS mileage rate.
Recording Studio Bookkeeping: Why 'Fully Booked' Studios Go Broke and How to Find Your Real Break-Even Rate
Recording studios typically cost $50–$120 per hour to operate before profit, yet many collect payment for only 60–70% of hours worked. How to calculate a true break-even rate (fixed costs plus debt service divided by realistic billable hours), track session vs. package vs. mixing revenue separately, handle album deposits as unearned revenue, and depreciate gear correctly under 5-year MACRS or Section 179.
Gymnastics and Cheer Gym Bookkeeping: Getting Tuition, Team Fees, and Meet Travel Right
A $3,600 competition-team fee paid in August isn't August revenue — it's deferred revenue recognized monthly across the season. How gymnastics and cheer gyms should book team fees, classify coaches (1099 vs. W-2), depreciate spring floors and mats under Section 179, and budget meet travel.
Idaho HB 559: Why 100% Bonus Depreciation Won't Apply on Your State Return
Idaho's HB 559, signed February 10, 2026, conforms to the OBBBA's expanded $2.5 million Section 179 cap but decouples from 100% bonus depreciation under Section 168(k), new Section 168(n) qualified production property expensing, and R&E transition relief — a divergence projected to cost Idaho businesses about $151 million in 2026. Here's who it hits and how the Form DBDA addback works.
