If a remittance or letter must be sent with the payment, indicate on the scanned vendor invoice or voucher "attachment" along with the coding and approval. Scan the attachment with the vendor invoice to Accounts Payable, who will print and include when payments are sent to vendors.
Attachments can also be sent via campus mail to the Business Office. In this case, indicate the "Attachment coming in campus mail" on the voucher or vendor invoice.
When attachments are needed for conference registrations or subscriptions, consider using a credit card for these purchases.
Remember that payments from W&L include remittance information on the check tear slip, which lists invoice numbers, invoice amounts, and payment notes, such as "registration for Prof Smith".
