The short version

  • Only Odoo has a free tier, so it costs nothing to try first.
  • Each has a real cost: Odoo the free plan is limited to one app, so any second module moves the whole account to a paid per user plan; 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: Odoo covers Sales management, 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.

Odoo

  • The free plan is limited to one app, so any second module moves the whole account to a paid per user plan
  • Standard runs $13.50 to $16.90 per user per month and Custom $20.40 to $25.50, both quoted with a yearly discount applied
  • Implementation services and custom development are not included in any plan
  • Odoo.sh hosting is required for custom modules and is charged separately from the subscription
  • SMS credits and AI scanning are billed on top of the per user price

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

Odoo: How much does Odoo cost per user?

Odoo pricing ranges from $0/month for one free app with unlimited users, to $13.50-$16.90/month per user for Standard, and $20.40-$25.50/month per user for Custom, depending on billing frequency (yearly vs monthly).

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.

Odoo: Is there a free Odoo plan?

Yes, Odoo offers a free plan that includes unlimited users for one app with hosting and support included on Odoo Online.

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.

Odoo: How does Odoo define a paying user?

A paying user is typically an employee who has access to the Odoo backend to create, view, or edit documents. Customers and suppliers accessing portals are free users and do not count toward the seat limit.

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.

Odoo: What is included in Odoo's Standard plan?

The Standard plan at $13.50-$16.90/user/month includes all Odoo apps, hosting, unlimited support and maintenance, daily backups, 24/7 monitoring and security, and free eLearning platform access.

Source
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.
