Flooring business taxes: how do you deduct LVP material costs without an accountant?

Been doing hardwood and LVP installs for 8 years now, mostly residential jobs around the greater Atlanta area, and taxes are killing me this quarter. I'm trying to figure out how to properly deduct all the vinyl plank flooring I bought from Floor & Decor last month, especially since some jobs got delayed and I have leftovers sitting in my van. Saw a post on r/Flooring where someone mentioned using QuickBooks for tracking material expenses, but I'm not sure if that covers everything for Schedule C. Out here, with the humidity messing up installs sometimes, I end up ordering extra to be safe, but does that count as a business expense or just waste? Also, anyone in the Flooring Contractors Network group dealing with state sales tax on supplies? I don't want the IRS breathing down my neck come April.

What state are you in, does that change how you file for materials?

Taxes on flooring supplies suck, had to pay extra last year because I didn't categorize my LVP right, pissed me off.

Use Jobber for invoicing, it integrates with QuickBooks and auto-categorizes material costs like your vinyl planks.

Customer calls at midnight about a squeaky oak floor I did last week, and I'm like dude it's taxes not your floor.

This year I deducted every damn chisel and underlayment roll, hit a personal best on write-offs.

Screw the big corps buying up small flooring shops, they don't deal with this tax BS like we do.

Man, I feel that, especially after seeing prices jump on engineered hardwood.

Track everything in a separate business account, makes audit-proofing easy for LVP and such.

Insurance companies and now the tax man, both out to get us floor guys.

Congrats on the write-offs, but yeah PE firms are ruining the margins we have left after taxes.

I hear ya, been nickel and dimed on every glue tub deduction for years.

Same boat, my back hurts from installs and now taxes hurt my wallet.

Dude walks in with a Home Depot cart full of cheap laminate and expects pro results, then skimps on paying taxes right.

Feels bad man, we're all grinding through this crap together.

Yup, solidarity in the tax trenches.

Totally get it, every receipt counts when you're solo.

Lol, my first tax year I deducted my coffee, got flagged instantly.

Proud to say I finally got my flooring deductions dialed in, no more surprises.

Those bloodsuckers in DC don't care about our LVP hauls or job site realities.

Govt squeezing us dry while materials cost an arm.

It's a racket, man, especially for trades like ours.

Hate how every little expense gets scrutinized.

Frustrated as hell with the new forms this year, took me all weekend.
