How We Work

Four steps. No mystery.

Every engagement follows the same disciplined path. You always know what is next, and you always know who is doing it.

01

Discovery Call

A complimentary 30 minutes. We scope what you actually need — and tell you straight if we are not the right fit.

02

Engagement Letter

Clear scope, deliverables, and a flat fee quoted upfront. No surprises. No hourly meter spinning in the background.

03

Onboarding & First Close

Books cleaned up if needed, prior returns reviewed, and your entire financial picture mapped to a single quarterly cadence. First close + first planning call within 30 days.

04

Quarterly Strategy

Quarterly check-in covering numbers, tax position, and whatever decisions are in front of you. The 11 months between returns are where the actual value lives.

For a decade I had a tax preparer who saw me once a year and a bookkeeper who knew nothing about taxes. They never talked. Switching to Milestone — one team handling both, talking constantly — caught $18K in deductions our prior setup missed in year one, and the planning conversations are worth more than the fee.

Questions We Get a Lot

Before we talk.

Are we too small for a CPA firm?+

Probably not. We work with businesses from $500K to $50M revenue. Below $500K, we usually recommend a solo CPA or simpler setup — and tell you that on the discovery call.

What is the difference between a CPA firm and a tax preparer like H&R Block?+

A CPA can advise on tax strategy, structure entities, run financial statements, represent you before the IRS, and sign reviewed/audited statements. A tax preparer files returns. Both have their place — the question is whether you need the strategic layer.

How does the flat fee work for a small business?+

You get one annual quote covering everything in scope: monthly close, business + personal tax returns, quarterly planning, year-end 1099s, and unlimited email. No "quick question" invoices. Most small business engagements run $9–28K/year depending on complexity.

Can you handle our payroll, or do we keep our current provider?+

We coordinate with your existing provider (Gusto, ADP, etc.) — that is usually the right answer. If you need a recommendation, we will give you one and stay out of the loop after that.

What if I am an S-corp owner taking distributions?+

Reasonable comp analysis, distribution vs. salary modeling, and Section 199A optimization are baked into the engagement. About 60% of our small-business clients are S-corp structures.

What if I want to grow past where you typically work?+

Our practice handles up to $50M. The same team scales with you — adding controller and CFO services as you grow, restructuring entities as needed, and walking you through capital events when they come up. No handoffs.
