In an effort to support an eco-friendly workplace, Ally Financial is going green when it comes to invoicing and no longer accepts invoices sent through the mail.

Invoicing through Ariba

We prefer that suppliers invoice Ally through the Ariba Network. It's convenient, efficient and secure. With Ariba, suppliers can:

  • Receive payment approximately 10 days faster than emailed invoices
  • Manage cash flow easily with the Ariba Discount ProfessionalTM management application
  • View real-time payment status online — no emails or phone calls needed

Emailing Invoices

Suppliers opting out of invoicing through the Ariba Network need to follow these instructions to avoid a rejected invoice or delayed payment.

Include the following information on the invoice:

  • Invoice date
  • Purchase order number (if applicable)
  • Ally contact name and email address

Scan and email invoices to

  • Attach one invoice per email (PDF preferred)
  • Invoice attachments should be of the highest resolution (300 DPI)
  • Attachment file names should not contain special characters or exceed 20 characters
  • The invoice must be received by Ally within 90 days of the date the product or service was provided to Ally

If you have any questions about invoicing, email us or call 1-888-901-4622 and select option 2 between 8 am and 5 pm ET.
