Deltek Review

Depends

Should I use Deltek?

Enterprise software for project-based businesses - deltek.com

· 2 days ago

Buy only if you're a mid-size or larger GovCon, A&E, or consulting firm needing ERP-grade project accounting. Small teams should skip it — simpler tools cost less and won't drown your staff.

Gotchas - check before you buy

high

Quote-based pricing; one user reports ~$8k per seat. Negotiate hard.

medium

medium

Legacy products (Vision, Maconomy) have published CVEs; verify patch status.

medium

Many overlapping products (Vantagepoint, Costpoint, Ajera) — wrong pick is costly to undo.
