What Do You Need to Start a Consulting Business?
You need about $30,000 in working capital, a clear professional positioning, and a client acquisition pipeline to start a consulting business. Revenue Map's consulting presets model a per-engagement practice at $10,000 per project with 36% delivery cost, spending $6,000 per month on the founder's draw, $1,200 on marketing, and $1,200 on tools and operating costs during the launch phase.
Consulting is one of the lowest-cost businesses to start because there is no inventory, no build-out, and no equipment beyond a laptop and a professional presence. The real investment is time: your runway while you build a pipeline and your delivery hours once clients arrive. Revenue Map models two delivery shapes for consulting, a per-engagement model pricing at $10,000 per project and a retainer model pricing at $1,800 per month per client, and the startup costs differ only in how aggressively you invest in marketing before the first contract lands.
The breakdown below covers what you actually need to open: working capital for personal runway, a marketing pipeline, delivery capacity, and the tools and insurance to operate credibly. The range between a $10,000 bootstrap and a $60,000 funded launch depends almost entirely on how many months of salary you need before your first paying client.

What Moves the Number
Delivery model shapes your cost base
Revenue Map models two consulting shapes. The per-engagement model prices at $10,000 per project with 36% loaded delivery cost, leaving 64% gross margin on each project. The retainer model prices at $1,800 per month per client with $820 of delivery cost, yielding about 54% gross margin but steadier revenue. Your choice determines whether you need project-based subcontractors or a delivery pipeline that scales with client count.
Client acquisition drives early spend
The per-engagement presets show a $15 CPC with 45% click-to-purchase conversion and 58% of leads from organic channels. The retainer model presets a $200 cost per lead with 45% organic. In both cases, organic channels like referrals, content, and speaking carry more than half the pipeline, so the paid marketing budget supplements rather than replaces relationship-driven growth.
Solo versus firm changes the salary line
The salary line moves from $6,000 per month at launch to $14,000 at maturity. A solo consultant treats this as personal draw; a firm builder uses it to hire a first associate. The gap between a solo practice at $6,000 per month and a small team at $14,000 accounts for most of the difference in annual operating costs.
