Common Mistakes to Avoid

The most frequent pitfalls across these providers come from mismatched scope expectations, inadequate internal alignment, and governance that is treated as an afterthought.

  • Selecting a payments delivery provider without planning for internal ownership of integration workflows

    PayPal Services accelerates integration through hosted checkout and PayPal buttons, but platform flows can limit full UI control for custom payment journeys.

  • Treating risk and controls artifacts as documentation instead of operational design

    Deloitte Financial Services Risk & Payments Consulting and PwC Financial Services (Payments and Financial Services Advisory) emphasize controls that align to regulatory expectations, but governance-first delivery can feel heavy if business teams expect fast iteration. Baker Tilly US, LLP (Financial Services Advisory) and KPMG Financial Services (Payments Advisory) focus on governance and audit readiness, which requires executive alignment to translate plans into operational delivery.

  • Choosing a purely tactical integration scope when the operating model must be transformed

    Accenture Financial Services (Payments and Payments Transformation) and Capgemini Financial Services (Payments Consulting) support end-to-end governance across transaction lifecycles, but their engagement structures can feel heavy for narrowly scoped payment changes.
