Before you sign the lease or add payroll, make sure booked retainers can cover about $25.3K in monthly revenue and keep Year 1 contribution margin near 76%. Keep one-time setup spend separate; the model also carries $73K of capex and a Month 2 cash low of $853K.
1Demand Proof$25.3K/moVerify signed retainers spell out strategy, creative coordination, project management, and post-launch support, because loose scopes won't hold the break-even run rate.
2Overhead Base$6.7K/moThe model has $6,700 in monthly non-payroll overhead, so don't add the $3,500 office lease unless client utilization can cover it.
3Margin Mix76% CMKeep contractor fees near 10% and project-specific software near 2%, or the 76% Year 1 contribution margin slips and break-even moves out.
4Hiring RampMonth 13Wait to hire the lead strategist and project manager until booked work can cover their load, because both start in Month 13 and the bench gets heavier after that.
5Cash Cushion$853K lowPlan cash for the Month 2 low point of $853,000 and keep the $73,000 of capex separate, so setup spend does not hide operating break-even.
6Acquisition Count20 acquisitionsA $50,000 Year 1 marketing budget at $2,500 CAC buys about 20 acquisitions, so track client concentration before you add payroll.
