The short version

  • Each has a real cost: Deltek not one product but a portfolio, including Costpoint, Vantagepoint, Maconomy, Ajera, ComputerEase, GovWin IQ and Replicon, so the right choice depends on the industry before the feature set; Protean ERP independent verification of this product is scarce, with little analyst coverage and few public customer references, so the vendor's own reference list is effectively the entire evidence base and you cannot triangulate a claim you are unsure about.
  • They diverge on capability: Deltek covers Project accounting, Protean ERP covers Formulation and recipe management.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Deltek

  • Not one product but a portfolio, including Costpoint, Vantagepoint, Maconomy, Ajera, ComputerEase, GovWin IQ and Replicon, so the right choice depends on the industry before the feature set
  • Pricing is not published anywhere and requires contacting sales
  • Built around project-based industries such as government contracting, architecture and engineering rather than general business

Protean ERP

  • Independent verification of this product is scarce, with little analyst coverage and few public customer references, so the vendor's own reference list is effectively the entire evidence base and you cannot triangulate a claim you are unsure about.
  • Small ERP vendors run thin implementation benches, so the consultant who knows your industry is often the only one who does, and if that person leaves during the project the timeline restarts rather than continuing with a replacement.
  • Niche ERP products are frequent acquisition targets, and an acquired product is normally placed into maintenance while investment moves to the buyer's own line, which shows up years later as an unpatched version you cannot leave.
  • Payroll, warehouse management, EDI and advanced quality are commonly either separately licensed or resold third party components in products of this class, so the quoted licence figure understates what a working installation costs unless you get the full module list in writing.
  • ERP data is the hardest thing in a business to move, and a small vendor's schema is proprietary and usually undocumented, so leaving means paying somebody to reverse engineer it and the practical decision horizon is closer to a decade than to a contract term.

Answered from the vendors’ own pages

Deltek: How much does Deltek Costpoint cost?

Deltek does not display pricing for Costpoint or other products on its website. Enterprise ERP pricing requires contact with Deltek sales.

Source
Protean ERP: Is a specialist process ERP worth it over a mainstream product with a process add-on?

It depends on how central formulation is to you. If recipes, potency and lot genealogy drive daily operations, a core capability beats an add-on because there is one vendor, one release cycle and one support call. If process needs are marginal, a mainstream product with a wider partner network is usually the safer institutional bet.

Deltek: What is the cost of Deltek Vantagepoint for architecture firms?

Deltek does not publish Vantagepoint pricing on its website. Pricing depends on firm size, employee count, and feature requirements.

Source
Protean ERP: What should I ask for in a demonstration?

Bring your own data. Ask them to build one of your real formulas, run a batch that produces a by-product, adjust for potency on receipt, then trace a finished lot back to supplier lots. Scripted vendor demonstrations avoid exactly these steps.

Deltek: Do Deltek cloud ERP solutions charge per user?

Deltek offers cloud ERP products but does not disclose per-user, per-month, or subscription rate information on its public website.

Source
Protean ERP: What contractual protection matters with a small vendor?

A documented and tested data extraction path, source code escrow with a release trigger you can actually invoke, named implementation staff, and clarity on what happens to your support terms if the company is acquired.

Protean ERP: How long does an implementation like this take?

For a single site batch manufacturer, plan on months rather than weeks, and assume the services and data migration bill is at least as large as the first year of software. Ask for a fixed scope statement rather than an estimate of days.
