Been using this now for 3 years and it's worth every penny. It's saved me SO much time having to make sure all of the items I have are listed particularly when the CRAYON EATERS here at Ebay started putting dollar and quantity limits on seller inventory. What the 3333 is that all about anyway?

Killed my listing
I lost my number one listing with over 5,000 sales because it closed on me. I had it set to 15 qty and after a customer purchased 15 it closed. It was fine when customers purchased once or twice. Already called eBay and eBay mentions if an app is not compatible with eBay listings, it would cause the listing to get messed up and ended itself. It's very important if the app is compatible since eBay mentions that they are always running updates. It took my four years to get to this point and now I have nothing to show for it. The app should be constantly updated to match eBay's updates to ensure it's in working condition.

Liked it. I was setup for autopay but it cancelled
Sorry if this is an ebay issue and not related to the app but the app company should have sent an email with a warning or something before cancelling. It really messed up some of my longstanding ebay ID's that had good sales history and will take years to get back not to mention all the sales I lost. I noticed that it was overdue which was weird cause for years it was just taken out of my paypal so I added my paypal again and also manually paid for my outstanding balance so I assumed all was good. Guess not

My account was hacked and the hacker signed me up for quantity manager so they could commit more FRAUD on my account. I was told that I cannot cancel this, and that I would have to pay for the service, even though FRAUD was documented on my account. It was probably Quantity Manager who hacked me, so they could get their money. EBAY and QUANTITY MANAGER ACTIVELY PROMOTE FRAUD. I disconnected my paypal account and will most likely stop using ebay entirely due to their absolutely terrible customer support

Bad billing practices and deceptive cancellation process and missing key features
- Kept billing me months after cancellation - 'Contact Us' links in ebay don't work so you cant actually talk to anyone when you have a problem - Numerous 'down times' when the App didn't work - Keeps the quantity steady in your ebay add after purchase, unless someone buys all you have listed in the ad and then the ad will end, really want the app to keep your items in stock even if you have someone buy all the listed items.

Solved all my relist problems!
If you are listing a large inventory this is the app to get to help you keep track of your quantities! Before this app I'd have to refund once a week on inventory sold that I didn't have. NOW with this app I NEVER WORRY ABOUT INVENTORY LEVELS EVER! Just put in the correct quantity the first time you list it and Quantity Manager handles the rest. I keep all my listings showing a quantity of 2, because if you are running a sale and it shows only a quantity of 1, the item will relist but that will end that item in the sale, so to keep it simple I just leave it at 2 showing and my sales run perfect now. Love Quantity Manager and it is well worth the price I pay for it so as not worry anymore about inventory levels!

Better than expected, great customer service!
This app was a real saver this season! In previous years, I manually changed quantities to keep the look of my inventory low. I bulked up on inventory this year compared to past and that combined with the QM app led to a 400% increase in Nov/Dec! Very easy to use and make changes. You receive email updates when an item is low or out of stock. After using for a couple weeks, I noticed the inventory alert emails gave the ebay item # but there was no info on the item but there was on the out of stock email. I contacted customer support and w/in 1 day I received a response. They updated the alert email! Now has the item description included in the email AND the variation if there is one. Easier b/c there are certain items I know I don't need to bother researching at a glance rather than investgating every email. The ebay item # also appears as link

This app is fantastic.
I always used to keep my inventory low manually----usually around 7 or so items, and I'd have to manually fix my inventory every 12-48 hours, depending on sales. This was a problem for several reasons: First, it was time consuming. Second, there were a few times where my items sold out while I was sleeping (thus unable to increase the quantity remaining). This app solves all these issues, and for a very low cost. I highly recommend it.

Life Saver!
Being a new seller on eBay, I am up against "selling limits". With as many items as we have listed, it is hard and time consuming to manage availability numbers since every item counts against us. This has been tricky to do and not have items end on us due to selling out. Enter QM...this app is easy to set up and works perfectly. No longer do I have to sit down and update quantities and check my dashboard to make sure I am not getting to close to the selling limits. I set a huge number globally for inventory, then set 3-5 on the display....then walk away! Well worth the money in time savings.

Easy to Set Up and Run - Intuitive and Logical User Interface
QM was easy to get up and running - it had clear step by step instructions presented in simple language that referenced specific entries on the screen. The User Interface is intuitive yet powerful. Tech support responded promptly to my one question. I gave up on a similar program offered by a different vendor because, unlike QM, it was difficult to set up and use - and lacked clear instructions. QM works exactly as advertised.

QM has made my life much easier
I like the QM as it has made the on hand count showing in ebay a lot easier then the way I was doing it. I have been using it for about 3 weeks. Checking each item sold after it happened was a pain and time consuming. I read your reviews before I signed up for it and learned what not to do by the reviews claiming your system did not work, they simply did not follow directions. I have over 1300 items listed now on ebay and Quantity Manager has made this part of the process automatic, I no longer have to monitor the quantites shown available for sale. If someone purchases all of the item QM immediately puts it back up on ebay so I don't miss any future sales. I highly recommend this application. Be sure to read and understand the instructions. Read the reviews of the people that were not happy and learn from their mistakes by reading the replies from the application tech guy. These are real helpful. I had this installed and running in less then 15 minutes.

I had an issue the first relist set, but they were very quick to correct the bug and restore my images? after midnight (my time) on a Sunday! You have to get out of the habit of changing inventory amounts via eBay, best to do that from QM. Is great for keeping inventory stock apparently low. I do not recommend that setting on items you could sell all of to one buyer. You know that though. :) Keeps perfect track of my inventory and relists as auto relist should -- with sold items deducted. LOVE! Absolute time saver! Wonderful!

This App cost me money
Way too confusing. I thought it would be simple. I listed an item with a quantity of 20. I told the app to say there was 2 left, like the app was designed to do. I sold 2 and the listing was ended. I had to list the item again. I thought maybe I made a mistake so I was careful to make sure I did it right the next time. I sold two more and the item ended again. I had to relist it AGAIN! As far as I'm concerned this app owes me $10. Why would I continue to give this app so much control over my listings? Not anymore!

Excellent Application - Excellent Service
I couldn't be more happy with this app. I mainly use it to manage inventory counts. Due to a lack of storage space, my inventory levels can't be very deep, so I am constantly receiving more inventory. Using eBay's edit function to revise quantities was cumbersome. With Quantity Manager it is a matter of a couple clicks and I'm done. No more waiting for slow pages to load and it even handles variations. On some items I use it to display less than I actually had on hand to give the buyer a sense of urgency and that really worked for me. The customer service is outstanding. They promptly answer every question. It is the first company I have ever dealt with that listened to my suggestions and actually implemented some of them. The fact that QM doesn't work well in conjunction with other apps that revise inventory counts (Turbo Lister, Prostores) hasn't been a problem since I knew this in advance and it makes sense. For the seller that is using eBay to revise quantities, QM is the ticket.

Not for big sellers
QM requests that you edit quantity directly from their interface. You cannot add more quantity from like Turbor Lister, it has to be done from QM. For a small seller that's fine but when you have 200 listings, you don't want to go to another program just to change quantity. Overall, it's not worth it because it will throw your entire inventory off if you don't do it on QM.
