Amazon require that, when sending stock updates to merchant listings, ChannelGrabber must also provide the Fulfilment Latency, sometimes also referred to as Handling Time in the same feed.

There are a couple of different ways you can manage this in ChannelGrabber.
​

1.  Navigate to Settings > Channel Management > Sales Channels and click the Manage button on the Amazon account profile:

2.  Under the Miscellaneous section, you will find various FBA related settings, and under those you will find the overall Fulfilment Latency setting for that Amazon account:

3.  Set this to the number of days that you are happy to commit to dispatching an Amazon order within, from the date the order was placed ie. if the order was placed on Monday, and you would be confident you could ship by Wednesday at the latest, set this to "2".  
​Amazon have strict penalties if you do not dispatch within the fulfilment latency that you have set, so be sure to give yourself enough slack to avoid upsetting Amazon by not meeting this deadline.

4.  Click the Save button below and this will then be the default Fulfilment Latency that ChannelGrabber sends along with the stock feed to your listings for this Amazon account.

5.  If you have more than one Amazon account connected to ChannelGrabber, repeat these steps for each separate account as needed.

In addition to the above default Fulfilment Latency, if you drop-ship, or rely on different suppliers to deliver your products, or even make products to order, you may find that different products have different handling times between the order being received and being ready to be dispatched, even though they are sold through the same Amazon account.  

If this applies to your business model, then we have the additional option to enable Product-based fulfilment latency, which means that your products in CG will utilise the default value for the overall Amazon account, unless you manually overwrite that by adding a different Fulfilment Latency at the product/SKU level.
​ 

1.  Complete the overall default Fulfilment Latency as above, then on the Miscellaneous section of your Amazon account settings, click the Product-based fulfilment latency toggle to set it to ON, then click the Save button:

2.  Navigate to your main Products page:

3.  On the main Listings tab, next to the Available stock level, you will see a main Fulfilment Latency column, which you can use to set an overall Fulfilment Latency per SKU, which will then be applied to all Amazon accounts where that SKU is listed:

4.  If you want to go a layer deeper and have a different Fulfilment Latency per SKU AND per Amazon Account, you will then see subsequent Fulfilment Latency (FL) columns for each Amazon account that you have connected to ChannelGrabber. Just make sure you do a stock push after making any changes to the FL for your listings. 

In this example, I want to have my Amazon EU handling time as 2 days for this SKU, but I want to give myself a extra day for US orders, so I set my Fulfilment Latency for the Amazon US account to 3:

 
Using this approach gives you greater flexibility to offer different delivery estimation dates to customers, which Amazon calculate based on your Fulfilment Latency and the Shipping Methods that you offer on each item, based on which SKU and which Amazon account the customer is buying from.

We hope this guide is useful and that this feature helps you take greater control of your Amazon listings/stock management in ChannelGrabber.
