Practical Tips to Improve Accuracy and Speed

Practical tips reduce errors, accelerate onboarding, and protect organizations from reporting or contractual disputes related to supplier relationships and documentation.

Verify legal name and EIN with authoritative sources
Before executing the Legal Supplier Letter, cross-check the supplier's legal entity name and EIN against IRS records or state filings. Accurate identification prevents backup withholding, incorrect information returns, and payment reconciliation delays.
Include clear payment and invoice references
Define payment terms, currency, acceptable invoice formats, and required purchase order or invoice references. Clear instructions reduce disputes, accelerate AP processing, and provide a defensible audit trail.
Document signer authority and attach supporting proof
Require a named authorized signer, include title, and attach corporate resolutions or powers of attorney when appropriate. This record reduces challenges to the supplier's binding authority in disputes.
Use secure eSignature and archive systems
Capture signatures with an audit trail, enable appropriate authentication, and retain signed PDFs in a secure repository with encryption and versioning to support compliance and evidentiary needs.
