The short version
- Only Billit has a free tier, so it costs nothing to try first.
- Each has a real cost: Billit annual billing required to get approximately 15% discount (one free month included); 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.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Billit
- Annual billing required to get approximately 15% discount (one free month included)
- Additional user seats cost €5 per user per month on top of plan price
- Overage pricing per document decreases with tier, penalizing rapid growth within a tier
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.
