Deloitte fits workflows that require enterprise integration planning with RBAC, audit evidence practices, and approval workflows, while Accenture fits small teams that need managed payment integration plus RBAC and audit controls integrated into payment event workflows.
Common selection and implementation pitfalls for payment services integrations
Most integration failures come from mismatched data models, unclear governance design, or automation that does not handle lifecycle complexity. Providers with deep APIs still require deliberate orchestration and mapping work.
The pitfalls below reflect cons seen across these providers and show where governance and automation can break down during real implementations.
Designing governance roles after building payment workflows
FIS and Fiserv both depend on deliberate role and configuration design, so RBAC assignments and change control should be modeled alongside payment configuration needs before automating reconciliation. Deloitte and Accenture also emphasize governance and approval workflows, so delaying governance setup can create rework across payment operations and access policies.
Assuming checkout-only payment flows cover reconciliation and dispute automation
Stripe, Adyen, and ACI Worldwide are built around payment lifecycle objects that extend into disputes, refunds, payouts, and reconciliation, so selecting a provider without mapping those states can cause state drift and custom reconciliation gaps. Stripe also requires careful orchestration around its complex object lifecycle, so automation that only listens to a subset of events can fail when refunds or disputes occur.
Skipping transaction and settlement data model mapping for internal ERP schemas
ACI Worldwide and TSYS both assume reconciliation-focused mapping into internal schemas, so ignoring schema alignment work leads to custom mapping overhead and reconciliation failures. Worldpay and Adyen also note that schema mapping and orchestration across captures, authorizations, and webhooks require careful internal alignment.
Implementing webhook automation without idempotency and retry handling discipline
Stripe shifts idempotency handling responsibilities to integrators, and Adyen and PayPal Commerce Platform rely on webhook event delivery for downstream synchronization. Without idempotent handlers and monitoring, automation can double-post accounting changes or trigger fulfillment multiple times.
Choosing an integration partner path that limits API quality or event coverage
TSYS integration depth depends on selected gateway endpoints and channel partner interfaces, so the automation and audit characteristics can vary by implementation path. Accenture and Deloitte provide strong governance and event-to-schema mapping through projects, so teams without internal engineering readiness can face operational overhead when integration scope expands.
How We Selected and Ranked These Providers
