Customer Service by Amazon fees

The Customer Service by Amazon (CSBA) fee is charged on each self-fulfilled shipped unit according to your customer service performance, which is measured by Contacts per Unit (CPU). CPU is the number of order related customer inquiries (for example, calls, instant messages, and emails) that Amazon handled on your behalf per total self-fulfilled shipped units. For example, if Amazon handled 40 customer inquiries on your behalf in the previous three months in which you shipped 1,000 self-fulfilled units, your CPU for the period would be 4% (40/1,000).

Table 1. CSBA rate card
Fee tier 1 2 3 4
CPU range <=5% >5% & <=15% >15% & <=30% >30%
Fee rate $0.10 $0.25 $0.50 $0.70

Your fee tier will be calculated based on your previous three-month’s CPU. For example, if your CPU from the previous three-months is 4%, your fee rate for this month would be $0.10 per self-fulfilled shipped unit. We will charge you a standard fee rate of $0.25 per self-fulfilled unit in some cases when your CPU performance is unknown or unreliable (for example, 30 or fewer self-fulfilled units shipped in the previous three months). We will communicate your fee tier on the first day of every month. Your CSBA fee rate will reduce as you improve your customer service performance by reducing your customer contacts.

Note: The CSBA fee will be charged per self-fulfilled shipped unit regardless of the customer contact volume. Your Fulfillment by Amazon (FBA) or Seller-Fulfilled Prime (SFP) units will not be charged as part of CSBA.

Frequently asked questions

How will I know my fee rate?

You can see your CSBA fee charge by going to the Payments Dashboard. We will also communicate your monthly fee rate on the first day of every month through an email along with the customer inquiry details.

Important: The CSBA fee rate will be updated monthly based on your previous three-month’s CPU, which is the number of order related customer inquiries that Amazon handles on your behalf per self-fulfilled shipped unit.

When is the CSBA fee charged?

Similar to referral fees, the CSBA fee is charged when you ship a self-fulfilled unit. Your fee rate for the month will be decided on the first day of every month. We will charge the fee rate on each self-fulfilled unit shipped in that particular month. For example, if your fee rate for October is $0.10, then we will charge you $0.10 on each self-fulfilled unit you ship in October.

Note: Once you enroll, you will receive a 30-day free service to try CSBA. The CSBA fee will be charged automatically after your 30-day free trial expires.

What will be my fee rate if I am a new seller or I joined CSBA in the middle of the month?

Once you enroll into CSBA, you will receive a 30-day free trial. After your free trial, we will calculate your fee rate based on your available CPU in the previous three months. In some cases when your CPU performance is unknown or unreliable (for example, 30 or fewer units in the previous three months), we will charge you as per the standard fee rate of $0.25 per self-fulfilled unit, until we have enough information to decide your fee tier.

What is Contacts per Unit (CPU)?

Contacts per Unit (CPU) is a way to measure your customer service performance. CPU is the number of contacts that are order related customer inquiries (for example, calls, instant messages, and emails) that Amazon handles on your behalf per self-fulfilled shipped unit. CPU calculation only includes order related customer inquiries handled by the CSBA team. It does not include FBA or SFP order related queries handled by Amazon or pre-order customer inquiries handled by you through the Buyer-Seller Messaging Service. We take the previous three months CPU data to decide your monthly fee tier as it improves CPU stability and reduces abrupt fee changes due to short-term customer service performance variations.

Can I reduce my fee rate?

Yes. You can reduce your fee rate by improving your CPU. CPU is a measure of customer service performance. As you perform better, your CPU will improve and your fee rate will be lowered. Here are some tips to help you improve your CPU:

Delivery experience

  • Provide valid tracking information to your order after shipment.
  • Select a carrier that provides end-to-end tracking information.
  • Set achievable shipping and delivery dates for your orders.
  • Ship the orders on time.

Return, Refund, and Cancelation

  • Show clear return and refund policies on the policy page.
  • Provide an accurate return shipping address.
  • If you can provide a better return and refund policy than Amazon’s standard policy, share it on your policy page.
  • Provide accurate stock volume information to avoid pre-fulfillment cancelation.

Product details

  • Provide accurate product information (for example, product color and size) and regularly update the product detail page.
  • Regularly update the frequently asked questions (FAQs) on the product detail page.
  • Improve packaging and product quality.
