- Each has a real cost: Brex the free Essentials tier is limited to two legal entities; Medius the sourcing, contract and procurement modules are considerably less developed than the AP core, so buying Medius as a full source-to-pay suite means accepting weak upstream tooling.
- They diverge on capability: Brex covers Corporate cards, Medius covers Invoice capture and coding.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Brex
- The free Essentials tier is limited to two legal entities
- Premium is $12 per user per month, so cost scales with headcount using the card
- Enterprise and Smart Card pricing is not published
- Eligibility criteria are not stated anywhere on the pricing page, which matters for a product that extends credit
Medius
- The sourcing, contract and procurement modules are considerably less developed than the AP core, so buying Medius as a full source-to-pay suite means accepting weak upstream tooling.
- Pricing is quote-only and driven by invoice volume, so a business with many low-value invoices pays disproportionately relative to the spend being controlled.
- Payments are billed on transaction volume separately from the AP subscription, which is easy to omit from a cost comparison against a licence-only AP tool.
- Private equity ownership since 2017 has produced an acquisition-driven product line, so payments and adjacent capability come from bought-in technology rather than the original platform.
- ERP integration depth varies sharply by system, and organisations on less common or heavily customised ERPs face integration work that lengthens the implementation.
