Where each one falls short

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

Basis Theory

  • The Starter plan is 995 US dollars a month before any volume, which is a real floor for an early stage company and puts the product out of reach of teams tokenising a few thousand records.
  • Starter is limited to the US region, so a company with European data residency requirements is pushed into a quoted Scale or Enterprise agreement immediately.
  • Log retention on Starter is 24 hours, which is well below what most security teams expect for a system holding cardholder data and forces an upgrade for reasons unrelated to volume.
  • Migrating away means moving card data out of the vault, which requires processor and assessor involvement and is slow, so the portability argument that attracts buyers cuts against them at exit.
  • An attestation of compliance covers the vendor environment, not your assessment; your assessor still decides what is in scope, and buyers occasionally discover their integration pattern pulled systems back into scope anyway.

Skrill

  • A currency conversion fee of 4.49 percent applies to most conversions
  • An inactivity fee of EUR 5.00 is deducted monthly after six months with no login or transaction
  • Card deposits carry a 2.50 percent fee
  • SWIFT bank withdrawals cost 2.80 percent with a minimum fee of EUR 3.5
  • Skrill to Skrill transfers cost 2.99 percent with a EUR 0.50 minimum on standard accounts, reduced to 1.45 percent only for True Skriller accounts
  • Crypto trading fees are tiered by VIP status, from 1.50 percent standard down to 1.30 percent at Gold and Diamond VIP

Answered from the vendors’ own pages

Basis Theory: Does this make us PCI compliant?

It removes cardholder data from your systems and gives you an AOC plus documented responses for most of a SAQ D. Your assessor still determines your scope, and a careless integration can pull systems back in.

Skrill: Is Skrill free to use?

Skrill operates on a freemium model. The digital wallet is free to open and use for basic features. The site refers to a fees page where transfer, conversion, and service fees are disclosed.

Basis Theory: What does it cost to start?

995 US dollars a month on Starter, including 20,000 tokens, a production PCI Level 1 environment and US hosting. Higher tiers are quoted.

Skrill: What are Skrill's fees for transfers and conversions?

Skrill lists transfer, conversion, and service fees but does not display the specific amounts on the homepage. Detailed fee structures are available on Skrill's dedicated fees page at /en/siteinformation/fees/.

Source
Basis Theory: Can we switch payment processors without re-collecting cards?

Yes, that is the main non-compliance reason to buy it. You hold the tokens and detokenise into whichever processor you route to.

Skrill provides international money transfers, online payment processing, cryptocurrency buying and selling, loyalty rewards through the Knect points program, and a mobile app. These services are included in the free account.

Source
