Vendor Self Service

Welcome to Alagasco Vendor Self Service

Alagasco is pleased to now provide Vendor Self Service (VSS) to our suppliers. VSS is a convenient new way to inquire about payment status and expected payment dates.  

VSS provides suppliers:

• access to invoice and payment status information
• service 24 hours a day, 7 days a week
• secure, up-to-date information about pending payments to assist in managing cash flow
• contact information to resolve invoices that are on hold or in incomplete status

Vendors can use this site to obtain information and answers for commonly asked payment questions, including:

• Has the payment for my invoice been issued?
• What is this check for?
• Is this a valid purchase order (P.O.)?
• How do I get a replacement check?
• How do I update my address?
• Why were funds withheld from my payment?
