Payment integration must reconcile intent, provider event, product state, and ledger
We integrate approved payment providers into web, mobile, SaaS, commerce, and marketplace products. The work covers checkout or billing state, tokenised payment data, signed events, idempotency, refunds, disputes, payouts where supported, reconciliation, monitoring, and operator recovery. The provider and client retain regulated, commercial, tax, accounting, and compliance responsibilities.

The problem
Sound familiar?
Checkout succeeds but order, subscription, entitlement, invoice, refund, or payout state changes late or twice?
Support and finance cannot trace a charge from product intent through provider events, internal records, correction, and reconciliation?
Short answer
Payment integration connects an approved provider to checkout or billing, product state, signed events, refunds, disputes, payouts where supported, and reconciliation. Start with one transaction type and test delayed or repeated events. A focused integration starts at $15,000 and usually takes six to twelve weeks after provider feasibility is confirmed.
The provider captured the payment. The product never granted access.
The signed event arrived twice and out of order. One worker retried, another timed out, and support saw a charge with no matching entitlement.
The integration is the state contract around money movement, not the checkout button.
Payment integration is a distributed transaction
A payment journey can cross product intent, customer authentication, provider state, internal order or subscription state, entitlement, invoice, refund, dispute, payout, finance records, and support. These systems do not update at the same moment. The integration must tolerate repeated, delayed, missing, and reversed events.
This remains a distinct service page because payment-provider boundaries, asynchronous events, money-state reconciliation, and operational recovery create a focused buyer intent beyond third-party API integration. The provider handles its regulated service; the client owns its business, customer, tax, accounting, and compliance decisions.

Starting investment
Focused integration, events, operator tools, tests, cutover, and handover
RaftLabs has published payment-related delivery, but any case study reflects its own provider, market, volume, architecture, and controls. It is not a guarantee for another product. Buyers should assess provider eligibility, state modelling, failure tests, reconciliation, security, customer communication, operator recovery, and ownership after release.
Use the provider's supported payment product before inventing one.
Custom code should own product state and recovery, not regulated payment functions the provider already supplies.
A fit
01
An approved provider fits the business, but product, billing, marketplace, or reconciliation logic needs engineering.
02
Product, finance, operations, risk, legal, tax, support, security, and technology owners can approve the flow.
03
Test accounts, representative transactions, failure cases, and operator users are available from $15,000.
Not a fit
01
The business still needs provider underwriting, licensing, legal structuring, banking, tax, or merchant-model approval.
02
A hosted checkout or billing portal already supports the need and only configuration is missing.
03
The proposed design would store sensitive payment data or move funds without approved scope and controls.
Bounded scope
What one payment loop may include
01
Checkout or billing state
Implement provider-hosted or tokenised capture where appropriate and map
product intent to provider objects. Model pending, requires customer input,
authorised, captured, failed, cancelled, expired, refunded, disputed, and
reversed states without equating a browser redirect with confirmed payment.
02
Signed events and idempotent processing
Verify provider events, retain their identifiers, acknowledge within supported
limits, and process safely through retries. Make handlers idempotent. Expect
duplicates, delays, and order differences. Re-fetch authoritative provider
state where required instead of trusting unverified client input.
03
Refund dispute and payout operations
Give authorised teams bounded tools for full or partial refunds, failed
payments, disputes, evidence status, and marketplace account or payout issues
supported by the provider. Use approval and audit controls appropriate to the
client. Never expose secret keys or make a local flag look like moved money.
04
Ledger references and reconciliation
Link product, order, invoice, payment, refund, dispute, fee, payout, and
correction identifiers without pretending the product database is the bank or
accounting ledger. Reconcile provider reports or APIs with internal records,
show exceptions, and give finance and support a traceable investigation path.
Choose the payment-integration path
Approach
Use it when
Hosted checkout or billing
Use provider-owned payment UI and lifecycle
Its product supports the model and minimises sensitive data exposure.
Custom provider integration
Own product state and experience
One provider fits, but application logic and recovery are distinct.
Billing platform
Use specialised subscription and revenue operations
Catalogue, metering, invoicing, entitlements, or finance rules exceed the gateway.
Payment orchestration
Coordinate several processors
Volume, markets, resilience, or routing value justifies added reconciliation and operations.
Design for events that arrive twice or not yet
Test repeated signed events, abandonment, authentication failure, authorisation without capture, and capture after timeout. Include partial fulfilment or refund, refund failure, renewal failure, plan change, dispute, payout hold, changed provider account, and reconciliation mismatch. Every state needs an owner and recovery path.
Cutover needs more than a successful test card. Confirm production credentials, restricted access, secrets, callback and redirect URLs, signatures, monitoring, alerts, rate limits, provider status, support procedures, real low-value transactions, settlement or payout visibility, refunds, reconciliation, rollback, and incident communication.
Delivery
From approved payment model to a reconciled production release
Four phases make failure handling and reconciliation part of the integration contract.
Phase 1
01
Define payment and responsibility model
Choose one transaction type, provider, markets, merchant role, product
states, refunds, disputes, payouts, ledger, controls, and acceptance cases.
Phase 2
02
Prototype provider and failure states
Test hosted or tokenised capture, authentication, signed events, duplicates,
delays, failures, reversals, refunds, disputes, and reconciliation.
Name provider and internal identifiers, reports, timing, currencies, fees, settlements, payouts, exceptions, ownership, and correction workflow.
Scope and price
A focused payment-provider integration starts at $15,000.
Start with one provider, one transaction type, and one reconciled product-state and recovery loop.
Starts at $15,000
Focused releases usually take six to twelve weeks. Subscriptions, marketplaces, several markets, migrations, or multiple processors add scope.
The estimate separates provider and banking fees, tax and legal advice, compliance validation, data migration, hosting, security, support, and payment operations.
Provider products stay in the decision
We use hosted and tokenised provider capabilities when they meet the product
and control requirements.
No regulated-service claim
RaftLabs integrates approved providers; it does not act as a bank,
processor, acquirer, money transmitter, merchant, tax adviser, or compliance
assessor.
We assess providers with documented APIs or supported integration products for the client's business model and markets. Feasibility depends on account approval, product, country, currency, payment method, merchant role, authentication, settlement, refunds, disputes, payouts, data access, rate limits, and licences. Provider selection and underwriting remain with the client and provider.
No. Hosted or tokenised provider components can reduce card-data exposure, but applicable PCI DSS scope depends on the full payment architecture, people, processes, integrations, and provider arrangement. The client and qualified assessors determine scope and validation. RaftLabs implements the approved design and evidence requirements; it does not certify compliance.
Yes, using approved provider products where they fit. Scope may cover plans, prices, trials, metered records, invoices, tax inputs, payment attempts, retries, credits, cancellations, entitlements, customer controls, and reconciliation. Product, tax, accounting, revenue-recognition, consumer, notice, refund, and collection rules require client and qualified-adviser approval.
Yes, when an approved marketplace payment product supports the client's platform role, seller locations, onboarding, payment methods, funds flow, commission, holds, refunds, disputes, and payouts. RaftLabs does not hold or transmit funds outside that provider model. The client and advisers define merchant, tax, regulatory, contractual, trust, and support responsibilities.
A focused provider integration starts at $15,000 and usually takes six to twelve weeks. Subscriptions, usage billing, several markets or methods, marketplace accounts, complex payouts, migration, finance integration, or several processors add scope. Provider and banking fees, tax and legal advice, compliance validation, hosting, security, support, and operations remain separate.
