DCAA Compliance Software Compared: Enterprise ERPs vs. Lightweight Tools for Small GovCons
Comparing Deltek and Unanet against lightweight QBO-based compliance tools — cost, implementation time, and when each makes sense for small government contractors.
If you're a small government contractor evaluating DCAA compliance tools, the landscape can feel overwhelming. On one end, you have enterprise ERPs that have dominated the space for decades. On the other, a newer category of lighter-weight tools designed specifically for small contractors.
This comparison is written to help you evaluate both categories objectively — based on cost, implementation time, compliance coverage, and fit for different company profiles.
The Enterprise ERPs: Deltek Costpoint and Unanet
Deltek Costpoint is the industry standard for mid-to-large government contractors. It's a comprehensive ERP that handles timekeeping, project accounting, cost accounting, billing, procurement, and reporting in one integrated system. It's been around since the 1980s and is trusted by contractors handling billions in federal contracts.
Unanet is positioned for the small-to-mid market. It's less complex than Deltek and was specifically designed for professional services firms doing government work. It covers project accounting, time, expense, billing, and reporting.
Typical costs: Deltek starts around $500–800/user/month for small implementations, with first-year all-in costs often exceeding $100,000 for a 10-person company (including implementation, training, and migration). Unanet is generally $300–600/user/month with implementation fees of $15,000–40,000.
Implementation timeline: Deltek takes 3–6 months. Unanet typically takes 6–12 weeks. Both require data migration from your current accounting system, configuration, training, and parallel running.
Strengths: Comprehensive compliance coverage, integrated modules (billing, procurement, proposals), strong reporting, well-understood by DCAA auditors, good for complex contract portfolios.
Limitations for small contractors: Expensive relative to contract revenue, long implementation when you may need to be compliant next month, requires abandoning your current accounting system, complex features you may never use, your CPA needs to learn a new system.
What we've seen in practice "Deltek's strategy uses job costing as a hook: once you're in for compliance, the same platform sells you project management, document management, CRM. The accounting core itself isn't necessarily better than QuickBooks — but the integration locks you in, which costs you the freedom to choose best-in-class tools elsewhere."

The Lightweight Category: Compliance Add-Ons for QuickBooks
A newer category of tools takes a different approach: instead of replacing your accounting system, they add DCAA compliance capabilities to your existing QuickBooks Online (or similar platform).
This approach leverages a structural strength of QBO that specialized ERPs can't easily replicate. As Brian Wendroff, CPA, puts it:
"QuickBooks Online's real advantage is its ecosystem. It connects to a marketplace of over a thousand business apps — automation tools, payment processors, payroll systems, CRMs. That kind of flexibility is what specialized ERPs can't easily match."
— Brian Wendroff, CPA — CFO & Co-founder, WiseCost · Founder, Wendroff & Associates, CPA
Products in the lightweight category include WiseCost (focuses on timekeeping, labor distribution, and JE posting to QBO), Hour Timesheet (DCAA timekeeping with QBO integration), Procas (time and expense with accounting integration), and ICAT (indirect cost allocation and tracking).
Typical costs: $100–400/month for a small team, with no implementation fees and no migration.
Implementation timeline: Hours to days, not months. Most connect to QBO via OAuth and import existing data automatically.
Strengths: No data migration, no disruption to existing workflows, fast setup, affordable, your team stays in the system they know, your CPA relationship is unaffected.
Limitations: Not a full ERP — you won't get integrated billing, proposal management, or procurement. May not handle CAS-covered contracts at the highest complexity level. You're running two systems (QBO + the add-on) instead of one.
The speed difference matters in practice. Jordan Glaze, Business Development Specialist/Accountant at Wendroff & Associates, CPA, puts numbers on it:
"For a 15-person company, moving to Deltek is usually premature. Implementation runs months. Finding an accountant who knows the system is hard. Adding a compliance tool to QuickBooks gets you the same compliance outcome in a week — sometimes a few days. The migration moment exists, but it's later."

When Enterprise ERPs Make More Sense
Enterprise ERPs earn their cost when you have more than 50 employees with complex organizational structures, when you manage 20+ active contracts simultaneously across multiple agencies, when your contracts exceed $50M and trigger full CAS coverage, when you need integrated billing (SF 1034/1035) generated from project accounting, when proposal management and what-if pricing analysis are core needs, or when you've outgrown QuickBooks for general accounting.
If three or more of those apply, the investment in Deltek or Unanet is probably justified.
When Lightweight Tools Make More Sense
Compliance add-ons earn their place when you have fewer than 50 employees, when you're pursuing your first or second cost-type contract, when you're already using QuickBooks Online and it works for your general accounting, when implementation speed matters (proposal deadlines, contract start dates), when budget is a factor (it usually is for small contractors), when your CPA manages your books in QBO, or when you want to prove compliance before committing to an ERP.
If most of those sound like you, starting with QBO + a compliance add-on is the lower-risk, lower-cost path. You can always move to an ERP later — but you don't need to start there.
"For a 15-person contractor, moving to Deltek or Unanet usually means spending more than you need to and signing up for a headache. Unless there's a specific capability gap, it's not the right call yet."
— Brian Wendroff, CPA — CFO & Co-founder, WiseCost
The Compliance Coverage Question
A natural concern: "Does a lightweight tool actually satisfy DCAA requirements?"
The SF-1408 doesn't specify which software you must use. It evaluates capabilities. If your combination of QBO + compliance tool provides GAAP-compliant accounting (QBO), cost segregation (QBO chart of accounts + classes), DCAA-compliant timekeeping (compliance tool), labor distribution (compliance tool), audit trail (compliance tool), and general ledger posting (compliance tool → QBO), then you satisfy the criteria.
Auditors evaluate the system as a whole, not individual components. A well-configured QBO + compliance tool passes the same pre-award survey as a well-configured Deltek instance.
The Decision Isn't Permanent
The most expensive mistake isn't choosing the wrong category — it's choosing nothing because you're paralyzed by the decision. A contractor running on spreadsheets while agonizing over Deltek vs. a lighter tool is losing time they could spend being compliant.
Start with what fits your current size and needs. If that's a lightweight tool, great — you'll be compliant in days and can grow from there. If you're large enough to justify an ERP, invest in the implementation. Either way, the goal is the same: an accounting system that passes the SF-1408 and keeps you audit-ready.
