Everyday Usage: How to Change a Listing from FBM to FBA
Transitioning your product listing from Fulfilled by Merchant (FBM) to Fulfilled by Amazon (FBA) is a frequent task for Amazon sellers aiming to scale, leverage Prime benefits, or optimize logistics. This process allows you to move from handling orders yourself (or through a third-party warehouse) to using Amazon’s sophisticated fulfillment network.
Everyday scenarios where the conversion is necessary include:
- Introducing new products where you want Amazon to handle storage, packing, and shipping.
- Scaling up a best-seller and no longer wanting to personally manage fulfillment.
- Seeking to win the Buy Box or make your listing Prime-eligible.
- Addressing restock limits, logistics, or seasonal demand by shifting inventory strategies.
Most sellers manage this process through Amazon Seller Central, either on a product-by-product basis (manual) or in bulk (using inventory file uploads or integrated third-party tools).
Benefits of Changing Your Listing from FBM to FBA
Switching an Amazon listing from FBM to FBA offers several key advantages:
- Prime Eligibility: FBA listings are automatically eligible for Amazon Prime shipping, boosting their visibility and desirability.
- Buy Box Advantage: FBA sellers are prioritized for the Buy Box, increasing conversion rates.
- Scalability: Amazon manages storage, packing, customer service, and returns, freeing you to focus on scaling your business.
- Faster Shipping: Customers perceive FBA as more reliable and expect rapid delivery.
- Reduced Workload: You no longer need to arrange shipping or handle customer queries about delivery.
- Trust Signals: FBA and Prime badges increase customer trust and can result in higher sales.
- Potential for International Expansion: Amazon can fulfill international orders for you.
- Improved Seller Metrics: Reduced risk of late shipments or order defects, as Amazon’s processes are highly standardized.
How to Choose the Right Conversion Method
When deciding how to convert your listing from FBM to FBA, consider:
- Number of Listings to Convert: For fewer than 5–10 items, manual conversion in Seller Central is fastest. For large catalogs, use bulk inventory file uploads or third-party tools.
- Familiarity with Amazon Processes: Beginners may prefer manual conversion to avoid file mistakes; experienced sellers can leverage file uploads for efficiency.
- Resource Availability: Have access to Excel (for bulk uploads), or subscriptions to third-party tools, if automating.
- Type of Products: Products with hazardous materials or batteries require additional information during conversion.
- Readiness to Ship Inventory: Only convert to FBA if you’re prepared to send inventory to Amazon’s warehouses.
- Desire for Parallel Listings: Sometimes, sellers want both FBM and FBA listings for the same ASIN. This is allowed (using different SKUs for FBA and FBM), but must be managed carefully to avoid overselling.
- International vs. Domestic Fulfillment: Ensure your FBA set-up matches your intended sales geography.

FAQ
- What is the difference between FBM and FBA on Amazon?
FBM (Fulfilled by Merchant) means you or a third party handle order storage, packing, shipping, and customer service. FBA (Fulfilled by Amazon) means Amazon manages those logistics for you, providing Prime shipping and often better customer service.
- Can I convert an active FBM listing directly to FBA, or do I need to create a new listing?
You can convert an existing FBM listing to FBA without creating a new ASIN or listing. Use the ‘Change to Fulfilled by Amazon’ action in Seller Central.
- Does converting to FBA delete or overwrite my original FBM listing?
No, the system maintains both fulfillment methods for the same ASIN, but each uses a unique SKU. You can run FBM and FBA offers simultaneously, insurance against stockouts.
- What information is required before converting to FBA?
You must provide accurate hazardous materials (hazmat) data, battery details (if applicable), packaging specs, and barcode preferences. This ensures compliance and determines FBA eligibility.
- How long does it take for conversion from FBM to FBA to show on Amazon?
Usually, the changed listing appears in ‘Manage FBA Inventory’ within 10–20 minutes after completing all prompts and data. Errors or missing compliance info can cause delays.
- Can I convert multiple listings from FBM to FBA at once?
Yes. Use the inventory file upload method or a third-party batch tool for bulk conversions. This saves time for large catalogs and ensures uniform compliance.
- What are the most common errors during conversion?
Typical issues include missing hazmat/battery information, incorrect SKUs or barcode preferences, and template formatting problems (for bulk uploads). Always validate your file before uploading.
- Will my item automatically become Prime eligible after converting to FBA?
Yes. Once inventory is received and checked in at an FBA warehouse, your listing gains the Prime badge, making it more attractive to Prime customers.
- Can I revert an FBA listing back to FBM?
Absolutely. Use the same process in reverse—’Change to Fulfilled by Merchant’—in Manage Inventory. Manage your stock accordingly, as FBA inventory must be removed from Amazon first.
- Should I switch all my products to FBA?
Not always. Evaluate factors like product dimensions, storage fees, sales velocity, category restrictions, and your ability to meet customer service expectations for FBM. Some products perform better in FBA; others, particularly oversized or low-volume items, may suit FBM.
