  • Can help lengthen payment terms by enabling enrolled Buyers to leverage an American Express billing cycle‡

*SIP is available to proprietary suppliers that meet certain requirements. SIP requires a separate agreement with American Express and fees apply. SIP may not be available to all buyers and eligible buyers must separately enroll in the product.


 

**The number of days by which your DSO is impacted may vary depending on your invoice dates, number of invoices, invoice amounts, the date on which you initiate an SIP payment and the date funds are made available and settled into your designated account. DSO may increase in certain instances.


 

†Subject to buyer application and approval. Supplier must also be enrolled in Supplier Initiated Payments (SIP) before they can initiate payments from a buyer’s SIP account. SIP is a payment method only and American Express is not responsible for verifying payment terms between the buyer and supplier. Buyer and supplier are responsible for agreeing on payment terms and ensuring that each payment processed through SIP is in compliance with such terms.


 

‡Provided that a buyer’s SIP account is in good standing, the number of days by which the buyer’s payment terms are extended will vary depending on (i) when during the buyer’s American Express billing cycle the supplier pulls a payment from the buyer’s account, (ii) the date that the transaction is posted to the buyer’s account, (iii) the date the buyer pays the amount due on their account, and (iv) the length of the applicable billing and payment cycles.

Late payments

SIP puts suppliers in control of when payments are initiated.

 

Problem: Buyers juggling multiple vendors or managing accounts payable (AP) backlogs may have a history of late payments that makes managing your cash flow a challenge.

 

Solution: SIP puts the power to pull a payment directly into the hands of suppliers.

How to get started

If you're a proprietary American Express B2B supplier, you can discuss SIP directly with your client manager.
