How to Modify an Existing AWS Marketplace Contract Using an Agreement-Based Offer (ABO)

Last updated: October 9, 2025

Need to add new services, expand contract value, or adjust pricing for an existing AWS Marketplace customer? Agreement-Based Offers (ABOs) are the key.

An ABO allows you to modify an active AWS Marketplace contract mid-term, giving you flexibility to adapt deals as customer needs evolve — without waiting for the current contract to expire.

🎯 When to Use an Agreement-Based Offer

ABOs are ideal in scenarios such as:

  • Adding additional products or services to an existing contract

  • Expanding contract value due to customer growth

  • Early renewals with new pricing or extended terms

🛠 How to Create an ABO in Clazar

Follow these steps to build and submit an Agreement-Based Offer directly from your Clazar dashboard:

  1. Go to the Private Offers tab in Clazar

  2. Click “Add Offer”, then select “Agreement-Based Offer” from the dropdown

  3. Enter your customer’s AWS Account ID

  4. Click “Get All” to fetch existing contracts tied to that account

  5. Choose the contract you want to modify

  6. Configure the new terms:

    • 🔁 Updated end date (if extending the term)

    • 💰 New pricing (only include the additional amount for price increases)

    • 📆 New payment schedule

  7. Review everything carefully and submit the offer



⚠ Key Considerations for ABOs

Before you proceed, keep these important notes in mind:

  • ✅ Once accepted, ABOs completely replace the previous contract terms

  • 📈 For price increases, only include the incremental amount in the ABO — not the full contract value. Important: If modifying usage dimension pricing for an offer where the customer has already been invoiced, set the contract value to $0 to avoid generating additional invoices. Only update the usage dimension pricing in the new offer.

  • 🧾 If there are unpaid installments from the current contract, ensure they are properly included or carried forward

  • 🔄 ABOs can only modify contracts under the same AWS listing — you cannot switch products using an ABO

  • ❌ If you want to terminate a contract instead of modifying it, you must submit a cancellation request via AWS Support
