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.

TrueLayer

  • Variable recurring payments, the strongest reason to choose TrueLayer, is a UK construct, and European businesses expecting the same capability in their market will not get it on the same timetable.
  • Payment conversion varies substantially by bank, and a bank with a slow or broken authentication journey drags results down regardless of vendor, so aggregate coverage numbers say little about your actual mix.
  • Pay by bank has no chargeback mechanism, which merchants like until a customer disputes a purchase and finds no scheme protection, making it a poor fit for categories where buyers expect card style recourse.
  • Pricing is unpublished and varies by market and product, so multi-country merchants cannot model cost without a full sales engagement and often find rates differ significantly between countries.
  • Open banking authentication requires the customer to leave the checkout and authorise in their banking app, and that redirect remains the largest source of drop-off compared with a stored card.

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.

TrueLayer: Is VRP available outside the UK?

No. Variable recurring payments are a UK capability. EU adoption is on a slower path, with UK commercial VRP expanding into ecommerce during 2026.

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.

TrueLayer: What does TrueLayer cost?

Not published. Per-payment fees are quoted by volume, market and product, usually with a platform component and a minimum commitment.

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.

TrueLayer: Are there chargebacks on pay by bank?

No. Bank transfers have no card scheme chargeback mechanism, which removes that cost but also removes buyer recourse, so it suits some categories and not others.

Basis Theory: Is data stored outside the United States?

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

TrueLayer: Which countries are covered?

The UK plus a substantial set of European markets under PSD2, though bank-level coverage and conversion vary by country and should be checked for your specific mix.
