The short version

  • Each has a real cost: Fundraise Up the fee is a percentage of donations, so cost rises exactly as the product succeeds, and a single large gift routed through the checkout carries the same rate as a twenty pound one unless the agreement caps it.; 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: Fundraise Up covers Embedded donation checkout, Medius covers Invoice capture and coding.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Fundraise Up

  • The fee is a percentage of donations, so cost rises exactly as the product succeeds, and a single large gift routed through the checkout carries the same rate as a twenty pound one unless the agreement caps it.
  • It is a checkout, not a CRM, so it is always an additional cost on top of a donor database rather than a replacement for one.
  • Donor covered fee opt in rates vary widely by audience, so an organisation with an older or offline leaning donor base absorbs more of the fee than the sales model assumes.
  • Design control is limited to what the embedded component exposes, so brand teams that want full control over the giving experience will hit boundaries.
  • Live recurring gift authorisations are held in the platform, which makes leaving considerably harder than adopting, because migrating active mandates risks lapsing donors.

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.

Answered from the vendors’ own pages

Fundraise Up: Is Fundraise Up a CRM?

No. It is a donation checkout that syncs into a CRM you already run, so budget for both.

Medius: Is Medius a procurement suite or an AP tool?

Primarily an AP automation platform with procurement modules attached. If sourcing is your main requirement, look elsewhere.

Fundraise Up: How does it charge?

A percentage of each donation, plus separately billed card processing. There is no flat licence that insulates you from volume.

Medius: Who owns Medius?

Marlin Equity Partners, which acquired it in 2017 and has funded several bolt-on acquisitions since.

Fundraise Up: Does the donor covered fee option remove the cost?

It shifts it. When donors opt in they pay the platform and processing fee; when they do not, the charity does.

Medius: How is it priced?

By quote, driven by invoice volume and entity count, with payments billed separately on transaction volume.

Fundraise Up: What happens to recurring donors if we leave?

Active recurring authorisations sit with the platform and its processor, and migrating them is the part of an exit most organisations underestimate.

Medius: Does it replace our ERP?

No. It sits alongside the ERP and posts approved invoices into it.
