A linked reference can support scope without confirming an exact forecast. Assumption entries identify values that still require local validation. Each field path identifies an input in the common business record.
- Model assumption
StartFigures selected the complete opening range, leasehold allowance, permits and deposits, pre-opening cost and reserve for one fixed-location case. SBA supports separating one-time and monthly costs; CBRE and TDLR provide premises and regulatory context. None supplies these dollar amounts. Replace them with the lease, authority fees, coordinated bids, project schedule and dated cash plan.

- Model assumption
Current vendor listings establish examples of individual salon furniture and appointment software; Texas provides one equipment-rule example. StartFigures authored the larger equipment, installation, tools, POS, supplies and inventory allowances. Quantity, freight, tax, plumbing, electrical work, ventilation, commissioning, warranty and local requirements remain unquoted.

- Model assumption
Every annual value is an authored scenario. Year-three revenue is exactly 18 completed visits × $115 × 6 days × 52 weeks. Sales-linked costs use the selected 16.5% envelope. Payroll and overhead are schedules informed by occupation, employer-tax, rent and processor context; none verifies this location's sales or expenses.

- Model assumption
The visit value, daily volume, schedule, ranges and ramp are StartFigures planning inputs. Classification, establishment counts, occupation data, appointment features and product architecture do not establish one salon's service mix, price, throughput, completion rate or launch curve. Validate them with a local menu, time study and retained POS sales.

- Model assumption
The $40,500 mature monthly fixed-cost input equals Year-three payroll and occupancy/other costs divided by 12. The 83.5% contribution margin is one minus the selected 16.5% sales-linked cost envelope. Published context identifies costs and systems to validate but does not verify either selected input.
