How can I set different prices for units in my Multi-Quantity Listings?

Multi-quantity listings can be a great long-term revenue stream on eBay, especially when you’ve found a reliable source for an item in high demand. The challenge comes when you restock. Each new batch might come from a different location or at a different price, making it harder to track your true revenue and profit. Flipwise solves this by letting you record unique acquisition data for individual units—or groups of units—within a single multi-quantity listing. You do this by creating separate Acquisition Lots.
What is an Acquisition Lot?
An Acquisition Lot (often called a "Lot" within Flipwise) is a collection of units within a multi-quantity listing. Each lot can have the following unique features:
- Purchase Price
- Purchase Location
- Purchase Date
- Storage Location
Example: You decide to start reselling boxes of paperclips. You find a great deal at Joe's Office Supply and purchase 20 of them for $1 a box. You create an eBay listing with a quantity of 20, and they start selling for $5 each. You are starting to get low on supply so you look for more boxes, and find an okay deal at Bob's Office Supply store, so you buy 10 more boxes at $2 each. You want to increase the quantity of your listing, but you want to make sure to track that some of those boxes have a higher purchase cost, and therefore lower profit. This is where you create separate lots, one for the initial purchase of 20 boxes, and one for the second purchase of 10 boxes.
How do I create new Acquisition Lots?
There are two ways to create a new Acquisition Lot for an item: in Flipwise, or in eBay,
Updating the Quantity on Flipwise
Find your item in Flipwise and go into the item detail page. You will see an edit icon next to the Quantity Purchased value.
Click on this icon and the following dialog window will appear:
This gives you two options. If you don't want to create a new lot, you can just update the existing quantity for the item by changing the number and clicking "Update quantity". But if you would like to create a new Acquisition Lot, click "+Add new lot", and a new dialog will appear (below) that lets you enter the specific information for the new lot of items that you have purchased. Note that you can enter the cost of these new items either by putting the overall cost of the lot, or by putting the individual unit cost. Flipwise will automatically calculate the other value.
When you have finished, click "+Add" and you will be taken to a new screen where you can view and manage your lots:
As you can see, there are 20 units purchased from Joe's Office supply on 10/1/2025 for $1 each, and 10 units purchased from Bob's Office Supply on 10/15/2025 for $2 each. Both are stored in Bin A, but they could also be recorded as being stored in different places.
You can continue to add new lots from this page by clicking the green "Add new Lot" button. And now that there are multiple lots, whenever you click on the edit button next to Quantity Purchased, it will take you directly to this new page.
Important: Creating a new lot in Flipwise will not increase the quantity in your eBay listing. You will need to specifically edit your eBay listing and increase the quantity to match the new total (the sum of all values in the "LEFT" column).
Updating the Quantity on eBay
You can also create a new lot simply by updating your quantity on the eBay listing itself. For example, if you changed the quantity of the eBay listing from 20 to 30, then a new Acquisition Lot is automatically created within Flipwise. This new lot won't have any acquisition data attached to it, and will be considered missing data, so you will need to go to Flipwise and input the missing data.
Go to your item in Flipwise, click the edit button next to Quantity Purchased, and then you can click on any of the values for the new lot and enter new values. Note that editing the Cost will let you change either the total price or the unit price, and then automatically calculate the other value. Read more about editing and deleting lots.
What happens when I sell an item that is part of a listing with multiple Acquisition Lots?
Now that you have multiple lots recorded within your listing, what happens when you make a sale? How does Flipwise determine which lot the sold item comes from? We use a concept called First-in First-out (FIFO for short). This means that Flipwise will look for the oldest available unsold unit (by Purchase Date) and attach that to the sale.
You can see here for example, that 5 boxes of paperclips have been sold, and they have all come from the first lot, so each of these sold units will have the purchase price of $1 when calculating Net Return. Units will continue to be pulled from this lot until all 20 have been sold, after which they will start being pulled from the second lot, and the profit will be based on a purchase price of $2/unit.
There may be cases where someone purchases multiple units, and those units will come from different lots, based on availability. In these cases, you will see multiple Sales Events in your item timeline for a single sale, so that it can properly calculate net return for each unit.
Note: The ordering used for this determination is based on Purchase Date. If you change the Purchase Date values of the different lots, the sale events will be reallocated so they continue to adhere to the FIFO standard.
