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.

PayPal

  • Currency conversion on international purchases and sends carries a 4.00 percent fee, and 3.00 percent in other conversion scenarios
  • Instant transfer to a bank or debit card costs 1.75 percent of the amount, with a minimum of 0.25 USD and a maximum of 25.00 USD
  • International personal transactions carry a 5.00 percent fee regardless of payment method, with a minimum of 0.99 USD and a maximum of 4.99 USD
  • Sending domestic personal payments funded by a credit card costs 2.90 percent plus a fixed fee of 0.49 USD
  • Instant transfers are capped at 25,000.00 USD per transaction

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.

PayPal: Does PayPal charge fees and when do they apply?

PayPal states that fees apply when converting currency and sending money to accounts in another country. Specific fee amounts are not disclosed on the homepage but are referenced in their published fee schedule.

Source
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.

PayPal: Is there a subscription cost to use PayPal's basic services?

No subscription fees are mentioned on the homepage. PayPal operates on a transaction-based fee structure for money transfers and payments rather than recurring charges.

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.

PayPal: Are there restrictions on when I can use buyer protection?

PayPal offers buyer protection for eligible purchases, but coverage limitations exist. A user agreement sets the specific conditions for protection eligibility.

Source
Basis Theory: Is data stored outside the United States?

Not on Starter, which is US only. Other regions require a Scale or Enterprise agreement.

PayPal: What payment methods can I link to PayPal?

PayPal's digital wallet allows storage of multiple payment methods and can be used for secure money transfers, payment requests, and checkout at major retailers.
