Don’t lock in rent, hires, tools, or marketing until the Year 1 job mix can carry the model’s $30.1k monthly fixed load. Break-even lands in Month 4, so the first projects, pricing, and cash cushion have to be in place before you spend.
1Demand proof$29.3k / $1.5k CACVerify clients will pay this project mix and that the $12,000 Year 1 marketing budget still lands customers near a $1,500 CAC, because that is what feeds the Month 4 break-even plan.
2Lease load$30.1k/moConfirm the $4,200 workshop and storage lease fits inside the full Year 1 fixed load of about $30.1k a month, including payroll, insurance, vehicle, software, photography, and utilities.
3Material stack70% CMVerify 12% for consumables and adhesives plus 8% for finishing and sealants, with logistics and referral fees near 10% more, so each job still leaves about 70% contribution.
4Crew ramp3.5 FTEMake sure one lead craftsman, one senior installer, one office administrator, and a half-time project manager can cover Year 1 work without overtime pushing labor above the model.
5Cash buffer$850k minHold cash above the $850k low point in Month 2, because capex and payroll hit before the business gets to Month 4 break-even.
6Launch gate$43.5k capexDo not release the precision saw, dust extraction, layout tools, van outfitting, air scrubbing, moisture testing, sample displays, and workstation spend until booked work can support a Month 4 launch and break-even.
