The default advice for CMMC is “hire a consultant.” For a large prime, that’s fine. For a small defense contractor working on thin margins, a $150,000–$500,000+ program can cost more than the contract is worth. The good news: for many small contractors, there’s a practical path that doesn’t start with a six-figure retainer. Here it is.

First, a reality check

You can’t skip CMMC — the 48 CFR final rule (published September 10, 2025) brought it into DoD contracts, and Phase 2 enforcement starts November 10, 2026 (BDO). But “you must comply” is not the same as “you must hire a $150K consultant.” Those are two different claims, and vendors profit from blurring them.

The practical, affordable path

Step 1 — Confirm your level and scope tightly

Figure out if you’re Level 1 (FCI only, 17 practices, self-assessment) or Level 2 (CUI, 110 controls). Then minimize your CUI footprint — the smaller your in-scope environment, the smaller and cheaper everything downstream becomes. Scoping is the single biggest cost lever you control. (See Level 1 vs Level 2.)

Step 2 — Start with your people

A large portion of the 110 NIST SP 800-171 controls come back to your workforce: security awareness, insider threat, incident response, acceptable use. Trackable, certificate-backed training is the fastest, cheapest way to make real, provable progress — and it’s something you can start this week, not next quarter.

Step 3 — Keep the evidence in one place

Assessors want proof, not promises. If your training records, policies, and compliance evidence are scattered across spreadsheets, email, and separate tools, you’ll spend the audit scrambling. A single source of truth for workforce records turns audit prep from a fire drill into a report you can pull on demand.

Step 4 — Use tooling priced for your size

This is where the money is saved. Instead of a consultant retainer, use a transparent, per-seat platform that publishes its pricing and costs a fraction of a program. You bring in specialized help only where you truly need it (e.g., a C3PAO for the Level 2 assessment) — not for the whole journey.

Step 5 — Grow into full compliance

Land on the piece that solves today’s pain (usually training for a deadline), then expand — connect your records, add compliance evidence, and build out. You don’t have to buy everything on day one.

What this looks like in practice

This is precisely the model Readiness OS was built around — “a platform built with economics in mind.” Four connected pillars (assess, train, secure, record) on one shared record:

• TrainVault — 13+ compliance courses, tracked, with audit-ready certificates. Starts at $99/mo + $8/user, self-serve, published pricing.
• WorkVault — one system of record for people, clearances, and readiness.
• Vaultline — turns your training and controls into CMMC/NIST evidence.
• WAY — verifies workforce fit.
