The short version
- Each has a real cost: GEP SMART gEP sells the software, the consulting and the outsourced procurement team, so the vendor measuring the savings is often the vendor delivering them, which makes independent verification difficult.; 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: GEP SMART covers Unified source-to-pay, Sage X3 covers Multi-company and multi-legislation finance.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
GEP SMART
- GEP sells the software, the consulting and the outsourced procurement team, so the vendor measuring the savings is often the vendor delivering them, which makes independent verification difficult.
- Nothing is published and reported entry points around half a million US dollars a year exclude implementation, which GEP typically delivers itself rather than through a competing integrator.
- Implementation being delivered by the vendor limits the pool of independent consultants who can advise you during the project or take over afterwards.
- Combined software and services engagements are difficult to unwind, because replacing the platform also means rebuilding procurement capability the outsourcer was providing.
- The platform is scoped for very large enterprises, so mid-market organisations face both a price and a complexity floor that no module selection brings down.
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
GEP SMART: Is GEP just a software company?
No. It sells procurement software, procurement consulting and outsourced procurement operations, and deals often combine all three.
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.
GEP SMART: What does GEP SMART cost?
Not published. Third parties report deployments from around 500,000 USD a year, scaled by managed spend, modules and users.
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.
GEP SMART: Who implements it?
GEP typically does, which shortens the project but reduces independent advice during and after it.
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.
GEP SMART: How does it compare with Ivalua?
Both are single-platform enterprise source-to-pay. GEP adds consulting and managed services; Ivalua is software only and stronger on direct materials.
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.
