1Demand Queue58 jobsConfirm you can book 58 first-year jobs across setups, restorations, appraisals, and custom builds, and track turnaround by service, because that is what makes break-even believable.

3Gross Spread88%-90%Test whether bespoke violins and violas keep an 88%-90% spread after parts, payment fees, and shipping, so custom work can fund the shop before volume rises.
4Staffing RampMonth 13Keep the apprentice hire off payroll until Month 13, and make sure the core team can handle 71 jobs in Year 2 before you add labor cost.
5Cash Cushion$941KCarry enough cash to reach the $941K low point in Month 35, because this workshop stays under pressure long before it pays back.
6Shop Buildout$80.2KSecure tonewood, fittings, climate control, humidity, ventilation, security, and the $80.2K buildout before taking deposits on custom commissions.
