Common pitfalls when selecting B2b Payment Software: governance gaps, weak exception mapping, and fragile reconciliation data
Many teams under-estimate the governance setup work because approval rules and roles directly affect payment release and operational recovery.
Other teams overfit to payment initiation and ignore how remittance context and exception handling behave when real payment data is incomplete or changes after onboarding.
Selecting a tool for payment initiation and discovering that AP and exception workflows must be rebuilt outside the system
Stripe can automate via typed webhooks, but its payment-first tooling leaves AP workflows to external orchestration, so integration scope must include invoice and remittance steps.
Assuming exception handling is covered without validating how the tool ties exceptions to payment runs or execution status
Kyriba and Versapay tie governance and exceptions to payment execution or payment runs, while Bottomline Technologies routes exception-first operations, so teams should validate these paths with their own failure scenarios.
Requiring invoice-to-payment context preservation but allowing remittance mapping to degrade when ERP formats differ
Paystand and Kyriba both emphasize remittance handling that preserves invoice context, while Paystand’s and Kyriba’s operational setup can increase when ERP and payment formats differ, so mapping coverage should be tested with real invoice samples.
Using vendor onboarding that is not aligned with how reconciliation references are passed at payment creation
Payoneer’s reconciliation quality depends on reference data passed at payment creation, so test cases must include real reference formats and changes to recipient details.
