Common pitfalls in e invoicing buying decisions
A frequent failure mode is treating mandate compliance as a standalone mapping task that does not drive validation outcomes and exception operations. Accenture’s emphasis on connecting compliance mapping to integrated invoice processing and exception operations exists specifically to prevent compliance work from detaching from invoice lifecycle execution.
Another frequent failure mode is underestimating governance discipline needed to prevent exception queues from becoming unmanaged. PwC calls out that services models require active client governance and integration ownership, while Genpact, Cognizant, and EY highlight that exception handling depends on workflow mapping and governance decisions.
Choosing a provider based on mandate readiness work without a defined exception routing model
Accenture’s mandate governance ties compliance mapping to integrated invoice processing workflows and exception operations, which keeps exception queues connected to mandate outcomes. Genpact also routes exceptions by invoice lifecycle state transitions into review and reconciliation steps.
Assuming self-serve administration will cover governance complexity for multi-workflow compliance
PwC notes that self-serve tooling depth is limited compared with pure software vendors and that the services model requires active client governance and integration ownership. EY also expects defined mappings and governance to keep exceptions manageable across many invoice workflows.
Buying orchestration without planning for workflow mapping and integration change management
Capgemini describes a project-heavy delivery model that requires change management and stakeholder alignment, which can derail rollout if governance and process mapping are not ready. IBM flags that setup complexity increases when multiple invoice formats and rules apply.
Under-scoping supplier onboarding provisioning and lifecycle governance for multi-entity programs
Wipro highlights provisioning and supplier onboarding support across procure to pay and record to report responsibilities, which prevents manual invoice rekeying from persisting.
