Where pressure washing companies buy
Pressure washing companies buy machines from equipment dealers and chemicals locally, often from pool supply or janitorial suppliers.

| Item | Why it is on the list |
|---|---|
| Sodium hypochlorite and surfactant | House and roof washes |
| Degreaser and rust remover | Concrete and stains |
| Spare nozzles, O-rings and quick connects | The parts that fail mid-job |

For the first order, price the starter kit too: gas pressure washer, 4 gpm class; surface cleaner; high-pressure hose, quick connects and nozzles; downstream injector or soft wash setup; extension wand and telescoping pole; garden hose and a water tank or buffer; pump sprayer for pre-treating; chemical-resistant gloves, goggles and boots. Bigger purchases to price at a dealer or rental house: trailer or skid setup with a water tank; dedicated 12 volt soft wash pump; second pressure washer; hose reels; water reclaim gear; multi-position ladder.
Opening a trade account
Bring your business name, tax ID and license number, and a credit application if you want terms. The big-box programs are compared row by row on Home Depot Pro vs Lowe's Pro. For the tools themselves, the pressure washing tools list has prices read on the makers' own sites (STIHL, Little Giant).
When supplier prices change
Update your pressure washing price list the same week a supplier raises prices. In Koira, that price list is what your estimates are built from.
