Laravel for fintech, money moves correctly the first time.

Yes. Laravel runs in production at major fintech companies including Square, MasterCard, and a range of payments, lending, and neobanking platforms. The framework supports the core fintech requirements out of the box: idempotent API design through Sanctum and middleware, comprehensive audit logging through Activitylog, role based access control, encryption at rest and in transit, and the operational substrate (ISO 27001, PCI DSS scope minimisation through tokenization, KYC and AML workflow patterns) that fintech compliance teams check. The framework choice rarely blocks a fintech engagement; the vendor choice often does.

Laravel itself is a framework, not a PCI DSS certified product, so it cannot be 'PCI DSS compliant' in isolation. PCI DSS compliance is a property of the application architecture, the infrastructure, the cardholder data flow, and the vendor relationships together. Laravel applications can absolutely be built to operate within PCI DSS scope with proper tokenization patterns (using Stripe Elements, Braintree, or Adyen tokenization to keep card data out of your servers), minimal scope architecture, encryption requirements, audit logging, and access controls. Our standard architecture pattern keeps the Laravel application out of PCI DSS Level 1 scope by ensuring no card data ever touches your servers, which dramatically simplifies your audit scope.

Payment integrations are one of the most carefully engineered parts of a fintech Laravel application. We use Laravel Cashier for Stripe and Paddle subscription billing, dedicated SDK integrations for direct payment APIs (Stripe Connect, Braintree, Adyen, Worldpay, Authorize.Net, Razorpay), webhook handlers with signature verification and replay protection, and idempotency middleware on all payment endpoints. Failed payments retry with exponential backoff, partial failures trigger compensation logic, and every payment event lands in a double-entry ledger with comprehensive audit trail. Webhook reception is decoupled from processing through queue jobs so payment provider retries do not cascade into double charges.

Six categories cover most of our fintech Laravel work. Payment platforms with multi provider routing, recurring billing, and merchant dashboards. Lending platforms with KYC verification, underwriting workflows, loan servicing, and repayment automation. Neobanking and digital banking with ledger systems, card issuing integration, and regulatory reporting. Wealth management and investment platforms with portfolio tracking, custody integration, and trade execution. Insurance technology with policy administration, claims workflows, and actuarial reporting. B2B financial workflows including invoice financing, supply chain finance, and cross border payments. Most engagements span one primary category plus integration touchpoints to others.

KYC and AML are typically delivered through integration with specialised compliance providers, not built from scratch. We integrate Laravel applications with Onfido, Jumio, Persona, Plaid Identity, Sumsub, ComplyAdvantage, Refinitiv World-Check, and similar providers for identity verification, document checks, sanctions screening, PEP screening, and ongoing monitoring. The Laravel application handles the orchestration: queueing checks, storing results with audit trail, triggering manual review when needed, escalating to compliance team through case management, and generating regulatory reporting (SAR filings where required). The KYC and AML provider stays in scope of their specialist compliance, the Laravel application stays out of that scope.

FinTech Laravel applications typically run $75,000 to $500,000 for the initial build depending on scope, integration complexity, and regulatory requirements. A focused payment platform with multi provider routing and merchant dashboards runs $100,000 to $250,000. A lending platform with KYC, underwriting, and servicing runs $150,000 to $400,000. A neobank or digital banking platform with ledger and card issuing runs $250,000 to $750,000. Long term support engagements typically run $12,000 to $35,000 per month depending on SLA tier, regulatory change tracking intensity, and ongoing integration roadmap. Full breakdown sits on our Laravel development cost page.

Double-entry ledger design is one of the most important architectural decisions in a fintech application. We typically build domain specific ledger tables (transactions, postings, accounts, balances) with strict invariants: every transaction is two equal and opposite postings, balances are derived from postings (never directly mutated), all writes happen inside database transactions with row level locking on involved accounts, and idempotency keys prevent double processing. The ledger is append only with corrections expressed as compensating transactions, never edits or deletes. Reconciliation jobs run continuously comparing internal ledger state to external payment provider state with discrepancy alerting. We do not use generic accounting packages for fintech ledgers because the constraints differ from accounting.

Idempotency is enforced at the application layer through dedicated middleware that requires an Idempotency-Key header on all state changing requests (POST, PUT, PATCH). The key is stored with the request fingerprint (method, path, body hash, user) and the response. Subsequent requests with the same key return the cached response without re executing the operation. Idempotency records have a configurable retention window (24 to 72 hours typical) after which the key can be reused. Combined with database transactions, queue job deduplication, and webhook replay protection, this gives the 'exactly once' processing guarantees fintech operations actually need. The pattern aligns with how Stripe, Adyen, and similar payment providers expect API clients to behave.

Yes. We have integration patterns for the common Banking as a Service partners including Synapse, Treasury Prime, Bond, Unit, Cross River Bank API, Galileo, Marqeta for card issuing, Modulr in the UK, and direct integrations with core banking providers where the engagement requires. The integration approach depends on the BaaS provider's API surface, the regulatory model (FBO accounts, principal models), and the operational responsibilities (KYC ownership, settlement, reconciliation) split between your team and the partner. We scope BaaS integration carefully during discovery because the architecture decisions are hard to reverse later.

Multi currency Laravel applications use a strict pattern: every monetary amount stored with its currency code (never assumed), all conversions happen at explicit boundaries with documented exchange rates, ledger postings are in the originating currency with derived reporting in functional currency. Cross border payments integrate with providers like Currencycloud, Wise Business, or direct correspondent banking partners. FX risk handling, settlement delay modelling, and regulatory reporting (BSA, FinCEN, OFAC) baked into the architecture from day one. Multi country deployments use region specific data stores with strict cross border controls aligned to local data residency requirements.
