Compliance requirements, procurement operations, and the AP workflows that break when they should not. Written by the Candex team.
Foreign contractors require a different compliance checklist than domestic vendors. Here is what gets missed, and why it matters before funds leave your account.
The vendor master optimizes for repeat suppliers. One-off vendors fall into exception handling that can take weeks. That gap has a cost.
Withholding rates depend on the supplier type, country of residence, and applicable tax treaty. Most AP teams only discover the gap when IRS correspondence arrives.
The hours billed and contracts delayed while a supplier waits in your onboarding queue add up. A closer look at what AP teams actually spend managing the backlog.
Enterprise resource planning systems were designed around repeat high-volume vendors. Long-tail and one-off international suppliers sit outside that model entirely.
Teams processing international payments without established vendor records have found a few approaches that work. None of them involve vendor master shortcuts.
ERP systems track purchase orders and match invoices. They do not handle the compliance layer for international payments: tax form collection, FX conversion, and sanctions screening.
Outstanding vendor payments at year end create accounting complications, audit exposure, and supplier relationship strain. A process checklist for clearing the backlog before close.
W-9 for US persons, W-8BEN or W-8BEN-E for foreign individuals and entities. Knowing which form to request before payment saves the follow-up chase during tax filing.
Spot purchases and emergency vendor engagements happen outside the standard procurement cycle. The resulting payment requests stress every part of an AP workflow built for planned spend.
Procurement teams committed to expanding their supplier diversity often hit the same barrier: onboarding timelines that disadvantage smaller and newer suppliers.
The first payment to a new vendor requires verification steps, form collection, and compliance checks that repeat vendors have already cleared. That difference is the source of most AP exceptions.
