Best practices for accurate and secure contractor invoices
Frequently asked questions and troubleshooting for contractor invoices
- Why is my invoice rejected by finance?
Invoices are commonly rejected for missing purchase order numbers, incomplete line items, absent supporting documentation, or mismatched contract rates. Verify the PO reference, include required attachments, and confirm the billed rates against the master services agreement before resubmission to reduce rejections.
- How do I ensure the signature is legally valid?
Use an eSignature provider that complies with ESIGN and UETA standards, captures signer authentication, time stamps, and creates an auditable certificate. Ensure the selected authentication method matches your internal legal requirements for enforceability.
- What do I do if a signer cannot access the invoice link?
Confirm the recipient's email is correct, check spam folders, and verify network access. If needed, resend the secure signing link or provide an alternate authentication method. Maintain a record of resend attempts for audit purposes.
- Can I edit an invoice after it is signed?
Once signed, the document should be treated as final; editing breaks the audit trail. If corrections are necessary, create a new invoice or add a signed amendment and route it through the same approval process to preserve integrity.
- How long should I retain signed contractor invoices?
Retention requirements vary by jurisdiction and company policy, but finance teams commonly keep signed invoices for at least seven years to satisfy tax and audit requirements. Apply retention schedules and secure archival storage to meet internal and regulatory obligations.
- What causes discrepancies between invoice and payment?
Discrepancies often stem from mismatched PO numbers, tax calculation errors, partial payments, or differences in billed versus approved hours. Reconcile line-by-line with purchase orders and payment remittances, and escalate unresolved items with supporting documentation.
