A shorter payment deadline can create pressure to skip controls, which is exactly when errors or fake invoices may slip through. Reconfirm the due date, any contractual consequence, and the approvers’ availability. Prioritize invoices by verified obligation and impact, not by the urgency claimed in an email.
Keep purchase matching, vendor verification, total calculation, and payment approval in place. If a required document is missing, request it and flag the invoice pending. Tell stakeholders early if review cannot finish by the new date; seek an authorized exception rather than quietly bypassing a control. Record who changed the deadline and what work remains. For an unfamiliar vendor or changed bank details, verify through an established contact channel before paying.
