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; Sage X3 sage sells X3 through partners rather than direct, so implementation quality varies more than the software does, and a weak partner produces a failed project on a product that works fine elsewhere.
They diverge on capability: Deltek covers Resource management, Sage X3 covers Multi-company and multi-legislation finance.

Sage X3

Sage sells X3 through partners rather than direct, so implementation quality varies more than the software does, and a weak partner produces a failed project on a product that works fine elsewhere.
Payroll is not part of X3 in most markets and is bought as a separate product or a third party service, so an organisation assuming a complete back office in one licence finds an extra vendor, an extra integration and an extra bill.
The product uses its own development language and toolset rather than a mainstream stack, so the pool of people who can maintain a customised installation is small, expensive and largely employed by partners.
Heavy customisation is possible and consequently common, and customised installations are harder to upgrade, which surfaces years later as a business running an old version because taking the current one means retesting and reworking every modification.
The North American partner ecosystem and third party add-on market are thinner than for the products X3 competes with, so niche requirements are more often met by custom development than by buying something already built.

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

Sage X3: Is Sage X3 a cloud product?

It is offered as a hosted subscription, commonly on AWS, but it is not a multi-tenant SaaS product in the way Plex or NetSuite are. You still have your own instance and you still own the upgrade decision, which is both more control and more work.

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

Sage X3: How do I choose a partner?

Ask for two references at your revenue, in your industry, on the version you are buying, and speak to them without the partner present. Ask who specifically will be on your project, how long they have worked on X3, and what happens if they leave mid engagement.

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

Sage X3: Does the licence cost tell me what the project costs?

No. For mid-market ERP the services bill commonly matches or exceeds the first year of software, and the subscription clock usually starts before go live, so the first year of licence buys considerably less usable time than it appears to.

Sage X3: Who should not buy X3?

A single entity operating in one country, because the multi-company and multi-legislation depth is the main reason to pay for this rather than something simpler, and a business paying for it without using it has overbought.
