Let’s talk about the fork in the road most new tax and accounting firm owners hit:
Do I build my firm from the ground up… or buy a small book of business and hit the ground running?
Both paths can work. Both have risks. Both require a unique mindset, investment, and timeline. In short, they are wildly different experiences.
If you’re a “rip the Band-Aid off” kind of person, a purchase sounds tempting. Clients! Revenue! A little momentum!
But is it worth it?
Let’s break it down — real costs, real upsides, and the big gotchas no one warns you about.
Option A: Buy a Book of Business
So, what actually happens when you buy a book of business instead of building from scratch? It’s not just about the money. It’s about the momentum, the mess, and whether the fit is right.
Here’s a real-world look at what you gain, and what issues you might inherit.
Pros:
- Instant cash flow
- Clients are already trained on monthly billing, year-end work, etc.
- May come with a junior staff member or support
- Reduces the “how do I find my first clients?” panic
Cons:
- You’re inheriting someone else’s tech stack, processes, and pricing (which may suck)
- The clients didn’t choose you — they chose the seller
- You may be tied into outdated systems, leases, or staff
- Big upfront cost (more on that in a sec)
Typical Purchase Price:
1.0x to 1.5x annual gross revenue
Example: A $150K/year solo practice might cost you $150K–$225K, sometimes paid over time
Option B: Start from Scratch
Thinking about building your firm from the ground up instead? This path takes longer, but it often leads to a firmer foundation.
You’ll call the shots. You’ll also carry the risk. Here’s what you need to weigh.
Pros:
- 100% control over your systems, pricing, niche, brand
- You attract clients who want you
- Leaner startup costs
- Better long-term scalability
Cons:
- Slower to get cash flowing
- Requires confidence in marketing + sales
- No safety net of inherited revenue
Startup Cost Range:
$5K–$15K (assuming you use smart tech, like our AI-powered starter kit)

Here’s the real decision point: Do you want speed or control?
Buying a practice = speed, but less flexibility
Building from scratch = control, but slower ramp-up
If you think “Well, I’ll buy and fix it later…”
That’s like buying a fixer-upper house and moving in during demo week. You’ll spend your first year undoing the old firm while trying to build yours.
Wild card option: Buy the right book + layer it with your vision
This works if:
- The seller has solid systems
- The clients align with your future niche
- The purchase includes transition support from the seller
- You already have a brand or plan to modernize with AI, automation, and clarity
We’ve seen firms 3x revenue in 18 months doing this — but only when paired with smart marketing and automation.

So… what should you do?
Ask yourself:
- Do I have capital to invest or time to hustle?
- Do I want a legacy firm… or something modern, lean, and scalable?
- Can I confidently market myself… or would I rather “inherit”?
One isn’t better than the other. But one is probably better for you.
Pro tip: If you start from scratch using tools like our AI-powered starter kit, you can automate 80% of the admin work and focus on what matters — attracting the right clients.
