Where each one falls short

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

Maxio

  • Entry-level Grow plan starts at $599/month, making it costly for very early-stage startups.
  • Pricing above the Grow tier requires a custom quote rather than transparent self-serve pricing.
  • Focused specifically on B2B SaaS billing, so it lacks general e-commerce checkout or consumer payment features found in platforms like FastSpring.
  • Advanced features like multi-entity support and expense amortization are gated behind paid add-ons.

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.
