How to Change Quantity on eBay Listings (2026 Seller Guide)

This guide shows how to update quantity on eBay one listing at a time, across a whole catalog, and automatically when the stock sits in a supplier's warehouse instead of yours. Every eBay rule below was checked against eBay's own help pages in September 2026, and the sources are listed at the end.

Quick answer: find the listing in Seller Hub or My eBay, select Edit (My eBay calls it Revise), change the Quantity field and save. You can change the quantity of a fixed-price listing at any time, including after it has sales and while an offer is open. Multiple quantities are a fixed-price feature, and eBay doesn't let you change an auction's format by editing, so an auction needs a new fixed-price listing. For a dropshipped catalog, our pick is Ecomli, our own non-API browser extension: its Stock Monitoring reads the Amazon or AliExpress supplier behind each listing and updates the eBay quantity by the rules you set.

• eBay counts the quantity down as units sell, so the field shows what is left, not what you first listed.
• Add new stock to the listing you already have. eBay says a listing's sales history is one of the things that decides its position in Best Match.
• Cancelling an order because you're out of stock counts as a transaction defect under eBay's seller standards.
• Turn on "Listings stay active when you're out of stock" and a zero quantity hides the listing instead of ending it.
• When a supplier holds the stock, the quantity needs regular re-checks, not a one-time entry.

How to update quantity on eBay: three manual routes

eBay gives you three ways into the same field. They all save to the same listing, so choose by how many listings you're touching and what else you need to change.

Seller Hub: edit the number in the listings table

1. Go to Seller Hub, open Listings, then Active.
2. Find the listing's row and hover over the figure in the quantity column until the edit link appears.
3. Type the new number and confirm.

This is the fastest route for one or two changes because the full listing form never opens. It's also the first method given in eBay's community forum thread on changing quantity.

My eBay or Seller Hub: Revise the listing

1. In My eBay, open Selling Activity and find the listing. In Seller Hub, tick the box beside it on the Active listings page instead.
2. Select Revise from More actions (in Seller Hub, use the Edit drop-down).
3. Scroll to the Pricing section and change Quantity.
4. Select Revise it to save the updated listing.

Use this route when you're changing more than stock in the same pass, such as the price, shipping details or photos. eBay's revise a listing page says there's no fee to revise unless you add a paid listing upgrade.

The eBay app

On your phone, go to Selling, open your active listings, choose to revise the one you want, then open Pricing and change Quantity. That's the path sellers give for the app in the same community thread, and it saves to the same listing as the desktop form, so there's nothing to redo later on a computer.

One detail catches people out on every route. eBay keeps track of the quantity as units sell, so the box shows what is still available, not what you first listed. List 20, sell 7, and the field reads 13. Type 20 back in and you're offering 20 more units, not topping the listing back up to 20.

What eBay lets you change, and when

Quantity is one of the most flexible fields on a listing. eBay's revise rules lock many fields once a listing has sales or an open offer, but the quantity of a fixed-price listing stays editable in every state below.

There is one move that changes quantity without you typing a number. From Seller Hub Active Listings, eBay lets you send a fixed-price listing to auction with Change to auction. If the fixed-price listing holds more than one item, one item goes to the auction and the fixed-price quantity drops by one. If it holds only one, the fixed-price listing ends. The views and watchers from the fixed-price listing don't carry over to the auction.

Why can't I update quantity on eBay?

When the quantity won't change or won't stay changed, the cause is almost always one of these five.

• It's an auction. Multiple identical items are a fixed-price feature, and eBay's revise rules say that in most cases you can't change a listing's format. Create a fixed-price listing for the item and set the quantity there.
• The listing has already ended. Without the out-of-stock preference, eBay ends a fixed-price listing when the last unit sells, so there is no live listing left to edit. Relist it, and turn on the preference before the next sellout (covered below).
• Another tool keeps overwriting it. In the community thread linked above, a seller raised the quantity, saw it back at 1 on the next edit, and mentioned that the listings were linked to Printful. Any inventory sync does this by design, Ecomli's Stock Monitoring included: it sets the number from its own rules on the next run. Change the rule in the tool, not the figure on eBay.
• You're editing the wrong level of a variation listing. Each variation carries its own quantity and price, so update the row for the size or color that changed. Once a variation listing has sales, eBay lets you add or remove variations but not edit the existing ones.
• A bulk file is still processing. A Seller Hub Reports upload isn't applied until eBay finishes processing it, which eBay says usually takes less than 15 minutes. Very large files take longer.

What quantity means on an eBay listing

Quantity is the number of identical items for sale in one fixed-price listing. You set it when you create the listing, and eBay subtracts each unit as it sells. With the default settings, the listing ends when the number reaches zero. Fixed-price listings are Good 'Til Canceled, so the listing stays active until you sell the quantity you set or you end it.

You always see the exact number left. Your buyers see it only if you allow it. The switch sits in Selling preferences under Multi-quantity listings, labeled Buyers can see exactly how many items are left.

Buyers sometimes see a message saying the provided quantity is not available. That generally means they asked for more units than the listing has left at that moment, often because other orders used up the stock or the seller lowered the number. If buyers report it on an item you can still supply, raise the quantity and it clears.

What the number controls once you change it

eBay gives two reasons to keep the quantity current in its multi-quantity listings help page, and both are commercial. First, a listing's sales history is one of the things that determines its position in Best Match results, so eBay tells sellers to add new stock to the existing listing rather than create a new one. The breakdown of how Cassini ranks eBay listings covers the other ranking inputs.

Second, overselling costs you. Under eBay's seller standards policy, an order the seller cancels because the item was out of stock counts as a transaction defect. Top Rated sellers must keep the transaction defect rate at no more than 0.5%, and the minimum standard allows no more than 2%. On a small store, a handful of stock-outs moves that rate fast. The seller performance metrics that decide your store health shows how those defects feed into your seller level.

Three smaller effects follow from the same edit:

• Fee timing. eBay charges a Good 'Til Canceled listing an insertion fee every month until all the items sell, you end it, or eBay ends it. A listing you keep alive keeps renewing.
• Buyer display. Whether shoppers see the exact count depends on your multi-quantity preference, not on the number itself.
• Concentrated history. Ten sales on one listing build one sales record. The same ten spread across ten duplicate listings build ten thin ones.

Once you pass a few hundred listings, keeping those numbers straight becomes its own job. The inventory system that scales past a few hundred listings covers how to organize it.

Setting quantity when the stock is not yours

Most quantity guides assume you're looking at a shelf. A dropshipper is looking at someone else's stock level on someone else's website, and that number moves without warning. Whichever supplier you use, the quantity you advertise is a promise you have to keep.

Run the numbers once and the risk is plain. Say a supplier page shows 14 units and you advertise 10. The supplier is selling the same item to everyone else at about four units a day. Two days later the supplier is down to six while your listing still says ten. One buyer ordering seven leaves you a unit short on an order you've already accepted.

Three habits prevent that:

• Advertise a fraction of the shelf. Publish a number you could still fill after a couple of days of the supplier's own sales, not their current total.
• Size the buffer by sales speed. A slow-moving part with 200 units in stock can carry a quantity of 20. A trending item with 14 units carries two or three.
• Re-read the supplier often. A copied stock figure is true only at the moment you copied it. Past a few dozen listings, checking by hand stops being realistic, which is the job Ecomli's Stock Monitoring does for Amazon and AliExpress listings.

The same checks protect margin when a supplier raises a price instead of running low, which is a separate failure with the same root cause. The guide to setting an eBay repricer around a margin floor works through that pricing side.

How to bulk update eBay listings

One listing is a click. Four hundred listings is a project, and the row-by-row route stops making sense somewhere around fifty. eBay's bulk listing tools cover most of it, and the right one depends on where your stock numbers already live.

Seller Hub multi-select edit

On the Active listings page, tick the listings you want and use the Edit drop-down to change them together. It suits a change that applies to a whole group, such as a category you're winding down.

Seller Hub Reports upload

This is the route when every listing needs a different number. eBay's Seller Hub Reports page gives the steps:

1. Open the Reports tab in Seller Hub and select Upload.
2. Select Get template, choose Listings as the source, and pick the template type for editing price, quantity or deleting listings.
3. Fill in the new quantities, then select Upload template and upload the file as .csv or .xlsx.
4. Wait for the "Your upload is complete" message and download the report of what changed.

Business sellers are opted in to Seller Hub automatically, and private sellers get access after at least one sale. Templates made in the older File Exchange tool don't carry over to Reports, so download a fresh template.

The Inventory API

Developers whose listings are managed through eBay's Inventory API can use the bulkUpdatePriceQuantity call, which updates up to 25 inventory items and their live offers per call. It needs a developer account and code, so most small sellers skip it.

Automation that sets the number for you

The first two routes still need someone to know the right figure. A tool that reads the supplier and writes the quantity removes that step, so the weekly spreadsheet ritual goes away. If you're still building the catalog rather than maintaining it, the four ways to bulk list on eBay compares the upload routes, the eBay seller tools comparison covers the wider software options, and the roundup of eBay order management software covers the tools on the order side. Watch your ceiling too: a quantity increase that pushes your monthly totals up can hit the selling limits on your account before it hits demand.

How to do this in Ecomli

Ecomli is a non-API browser extension for eBay dropshippers. It works through the eBay seller account already signed in to your desktop Chrome browser, so there is no API connection to authorize. For quantity, the job is to put your listings under Stock Monitoring and choose what happens when a supplier runs low or sells out.

1. Get your listings into Ecomli. New listings come from Create Listings: paste Amazon or AliExpress supplier links, or send picks from Product Hunting, and Ecomli fills in eBay's listing form in your seller session. Listings you already have can come across through Migration from AutoDS, EcomSniper or the eBay Active Listings CSV from Seller Hub. Ecomli reads the supplier from the Custom label (SKU) or a supplier-URL column, and holds rows it can't read for you to add the Amazon or AliExpress link. Your listings stay live on eBay throughout.
2. Set your Stock Monitoring rules. Choose your markup, the out-of-stock rule (set the quantity to 0 or end the listing), the restock quantity to restore when stock returns, and a price-change tolerance so small supplier price moves are ignored.
3. Turn on eBay's out-of-stock preference if you choose quantity 0. With "Listings stay active when you're out of stock" on, a zero hides the listing and keeps its sales history instead of ending it.
4. Run Stock Monitoring with Chrome open. Ecomli checks each supplier's stock and price, then updates the eBay price and quantity, or ends out-of-stock items, and shows the results. It runs in your desktop browser while the browser is open, so the timing depends on when your browser is running. If a supplier page can't be read, the listing is held unchanged instead of being ended, and it appears in the results for you to check.
5. Handle the orders that come in. Starter uses manual ordering. On Pro, you click Auto Order and Ecomli places the supplier order in your own browser. On Scale, Advanced Auto Ordering runs on Ecomli's servers and places the supplier order for new eBay orders without a click, as long as each order is within your buying limits (maximum purchase price and maximum loss).

Every plan includes Stock Monitoring and unlimited active listings, and you can create an Ecomli account when you want to set these rules on your own store.

When zero is the right quantity to set

Zero is a real setting, and it behaves differently depending on one account preference. By default, a fixed-price listing ends when the last unit sells. Turn on the out-of-stock option and the listing stays active but hidden from search results until you raise the quantity again. To switch it on, go to Selling preferences, scroll to Multi-quantity listings, and select the toggle beside Listings stay active when you're out of stock.

The rules worth writing down, all from eBay's multi-quantity help page:

• The preference applies to all your existing and future multi-quantity listings until you turn it off.
• A listing reaches zero either because everything sold or because you set it there, and it reappears in search when you increase the quantity.
• If a listing sits at zero for 180 consecutive days, eBay ends it.
• If a Good 'Til Canceled listing holds zero for a whole monthly billing period with the option on, you may qualify for an insertion fee credit and a credit for any advanced listing upgrade fees for that period.
• eBay says the option may help protect you from a transaction defect for running out of stock.
• If you relist a variation listing, any variations at zero come back at their original quantity, so check the numbers before it goes live.

Choosing between hiding and ending comes down to whether the supplier is coming back. A seasonal item from a supplier who restocks every spring belongs at zero with the preference on. An item the supplier has stopped carrying is better ended and replaced. The full walkthrough of eBay out-of-stock control sets out that decision with the fee cycle attached, and when you do bring something back, the relisting playbook covers what carries over and what resets.

How much stock to put behind one listing

The last decision is how much of your available stock to advertise on a single listing. A high number concentrates sales history in one place, which helps visibility, and it also concentrates your exposure if the supplier runs short. A cautious number does the reverse. Here is how the four common approaches compare.

For most dropshipped catalogs the small buffer is the safer choice. It captures multi-unit orders without betting your account on another company's warehouse. The exception is a supplier you've watched hold deep stock for months, where matching their number is reasonable as long as something checks it. Variation listings need the same call per variant, which the dropshipper's guide to eBay variation listings breaks down, and an auction that ended with more interest than stock can be a candidate for a second chance offer to the underbidders rather than a straight relist.

Who Ecomli suits here, and who it doesn't

Ecomli is a good fit if you:

• Dropship on eBay from Amazon or AliExpress and have more listings than you can re-check by hand.
• Work from a desktop Chrome browser you can leave open while Stock Monitoring runs.
• Want to bring an existing catalog across from AutoDS, EcomSniper or an eBay Active Listings CSV without taking listings down.

It's the wrong tool if you:

• Hold your own stock and change quantities a few times a week. eBay's own revise form and Seller Hub Reports are enough.
• Buy from suppliers other than Amazon and AliExpress, because Stock Monitoring reads those two.
• Sell on channels other than eBay. Ecomli is built for eBay only.

Frequently asked questions about eBay listing quantity

How do I update quantity on an eBay listing?

Find the listing in Seller Hub or My eBay, select Edit or Revise, change the Quantity field in the Pricing section, and save. In Seller Hub you can also hover over the quantity in the Active listings table and edit it in place. On the app, go to Selling, open the active listing, revise it and change Quantity under Pricing.

Why can't I update quantity on eBay?

The usual causes are an auction-style listing (multiple quantities are a fixed-price feature), a listing that already ended when it sold out, another tool that overwrites the number on its next sync, or a variation listing where the quantity has to change on the specific variation. Fix the cause and the edit will stick.

Can I change the quantity while a Best Offer is open?

Yes. eBay's revise rules say that when an offer is sent or received you can still change the available quantity. What you can't change at that point are the item specifics, the existing shipping details and the description.

Does changing quantity reset my listing's sales history?

No. Revising the quantity edits the same listing, so its sales history stays with it. That's the reason eBay tells sellers to add new stock to the existing listing instead of creating a new one: sales history is one of the things that determines Best Match position. Ending the listing and creating a new one is what starts the record from scratch.

How do I bulk update quantity on eBay?

For a group change, tick the listings in Seller Hub Active listings and use the Edit drop-down. For a different number on every listing, download the price and quantity template from Seller Hub Reports, fill it in, and upload it as .csv or .xlsx. For dropshipped Amazon and AliExpress listings, a tool like Ecomli's Stock Monitoring sets the numbers from the supplier for you.

What does quantity mean in an eBay listing?

It's the number of identical units still available to buy in a fixed-price listing. eBay subtracts each unit as it sells, so a listing that started at 20 and has sold 6 shows 14. Reading it as the original figure is the most common way sellers accidentally double their advertised stock.

How often should I update listing quantity?

It depends on how fast the source moves. Stock you hold yourself can be reconciled whenever it changes, or weekly. Stock held by a supplier who also sells to everyone else changes far more often than anyone can track by hand, which is why dropshippers let a tool like Ecomli read the supplier and write the number on each Stock Monitoring run.

What is the best way to keep eBay quantity in sync with a supplier?

For Amazon and AliExpress dropshipping, our pick is Ecomli. We make it, so weigh that. Its Stock Monitoring checks each supplier's stock and price, updates the eBay quantity and price by your rules, and holds a listing unchanged when a supplier page can't be read. If you hold your own stock, eBay's Seller Hub Reports upload does the job without extra software.

The bottom line

Treat the quantity box as a number with a maintenance schedule, not a field you fill in once. Kept current, it protects the sales history that earns your listings placement and keeps out-of-stock cancellations off your defect rate. For a few listings you stock yourself, the Seller Hub edit takes seconds. For a dropshipped catalog, Ecomli is our pick: it reads the Amazon or AliExpress supplier, sets the eBay quantity by your rules, and places supplier orders within your buying limits from the Pro plan up.
