Message from Rudy Batts, Director of Procurement, Slack

At Slack we’re driving to make work life simpler, more pleasant and more productive. This goal extends to supporting our suppliers too.

Were your invoices rejected because no Purchase Order was referenced on your invoice? Do you need greater transparency or faster payments? Consider these two options powered by Coupa:

1. Join the Coupa Supplier Portal (CSP) – It’s secure, free, and you gain the benefit of viewing your Purchase Orders, uploading your invoices and monitoring your payments.

2. Accept Credit Card Payments using Coupa Pay – evolving virtual credit card solutions from Coupa give Slack the ability to pay in new way

If you are interested in joining the Coupa Supplier Portal, receiving Credit Card Payments or have any questions, our team is ready to help you at [email protected].

Do you prefer a more sedate and nostalgic payment process? If so, please continue to submit your invoices via email to the address provided on your Purchase Order.

Thank you for your continued partnership with Slack.
