Deltek Vantagepoint is a full project-based ERP — general ledger, accounts payable/receivable, billing and resource planning in one system — built primarily for architecture, engineering and consulting firms with complex accounting needs. Deployments commonly run into six figures in the first year.
Hourglass isn't an ERP. It's a focused delivery platform — time tracking, resourcing, budgets, invoicing and client visibility — that a small-to-mid-size firm can set up itself, the same day, at a published price.
Try Hourglass freeDeltek
A project-based ERP with full financial management — general ledger, AP/AR, project accounting — alongside resourcing and delivery. Implementation typically runs 8 weeks to 9 months depending on complexity, with mid-market first-year costs commonly reported between $100,000 and $600,000.
Hourglass
Time tracking, resourcing, budgets, invoicing and client visibility in one self-serve platform, priced in GBP from free. Not a general ledger replacement — Hourglass connects to your existing accounting system (Xero) rather than replacing it.
Deltek is a full accounting ERP; Hourglass is a delivery and invoicing platform that plugs into Xero. If you need general ledger and project accounting in the same system, that's a real Deltek advantage — most smaller firms don't.
Deltek implementation time and cost ranges per third-party analysis (Vendr, 2026) — Deltek does not publish list prices.
You’re a 5–80 person agency, consultancy or MSP — not a firm that needs a full project accounting ERP
You already have accounting software (Xero) and want delivery/invoicing that connects to it, not replaces it
You want a published price and a working trial today, not a multi-month implementation project
You want UK-operated support and GBP pricing, not a US-headquartered enterprise vendor
You need to be live in a day, not planning an 8-week-to-9-month rollout
If your firm needs full project-based general ledger accounting alongside delivery — common for larger AEC and government-contracting firms — Deltek's depth may genuinely be the better fit. This comparison is aimed at smaller, growing firms deciding between the two.
