Where each one falls short

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

Formance

  • Formance holds no money and provides no regulatory cover, so it must be paired with a payments provider or bank, and buyers occasionally mistake a ledger for a treasury system and discover the gap late.
  • Numscript is a domain-specific language your team must learn, and while it makes complex splits expressible it also means transaction logic sits outside the languages your engineers already debug well.
  • Self-hosting a ledger that must never lose or duplicate a transaction is a serious operational commitment covering backups, upgrades and Postgres tuning, which is real cost the zero licence fee hides.
  • Enterprise pricing is not published, so the difference between the free path and the supported path cannot be evaluated without a sales conversation.
  • The company is much smaller than the incumbent alternatives, and while the MIT licence protects the code it does not protect the roadmap, so features on the hosted side may arrive slowly or change direction.

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  • Pricing is unpublished and varies by market and product, so multi-country merchants cannot model cost without a full sales engagement and often find rates differ significantly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

Formance: Is Formance really open source?

Yes. The core ledger is MIT licensed with full source access and no deployment restrictions.

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.

Formance: Does Formance move money?

No. It records and orchestrates movements; the actual payments happen at a PSP or bank you connect.

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.

Formance: What does the enterprise version cost?

Not published. It is an annual subscription quoted per customer.

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.

Formance: Do I have to use Numscript?

Yes for anything beyond the simplest transfers. It is how multi-party transactions are expressed atomically.

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.
