page and click the button that says &#8220;Display = Inventory&#8221;.\u00a0 This tells QM to display on eBay exactly what you have in stock.\u00a0 Once this button is clicked a notification will appear stating that your listings will be modified shortly.\u00a0 For performance reasons QM does not do bulk updates immediately but instead puts them in a queue to be performed by a separate process.\u00a0 The entire process should not take more than 10 minutes unless you have several thousands listings on eBay.\u00a0 Also, MVL listings usually take longer to update than normal listings due to eBay limitations.\u00a0 Once you have verified that your listings are back to normal you are free to unsubscribe.<\/p>\n<p><big><strong>But I didn&#8217;t follow directions and my Inventory is wrong.\u00a0 How do I fix it?<br \/>\n<\/strong><\/big><\/p>\n<p>If you do happen to unsubscribe but have ignored the instructions above you are not alone.\u00a0 There are two easy solutions to this issue.<\/p>\n<p>You can resubscribe to one of our monthly plans and then follow the directions above.\u00a0 Keep in mind that you must correct for any sales you&#8217;ve made since you unsubscribed because QM did not see them.\u00a0 Once you have fixed your listings simply unsubscribe again.\u00a0 Monthly plans are prorated so the most this could cost you is $0.18.<\/p>\n<p>The other solution is to simply contact us and request that we send you your Inventory counts.\u00a0 When you unsubscribe your listing details are not immediately purged and most likely we still have them.\u00a0 Keep in mind that we must have a way to verify who you who you claim to be as we are not going to send your details to anyone who just asks for them.\u00a0 Sufficient proof would include contacting us through our helpdesk or website using an IP address you logged into our service from or requesting details sent to the email address you had on record.<\/p>\n<p><big><strong>Will QM ever be able to restore listings on unsubscribed users?<\/strong><\/big><\/p>\n<p>Unfortunately this will probably never be possible.\u00a0 The only way it could work is if eBay allowed a grace period between unsubscribing and token revocation.\u00a0 We believe this would be a bad idea because it could lead to apps getting stuck mid way during cleanup.\u00a0 It is not a good idea to assume that the user really does want their quantities restored at the end.\u00a0 We&#8217;ve spoken to many users over the years and some simply didn&#8217;t want QM to reset their Inventory before unsubscribing.\u00a0 Thus, the best solution is to leave responsibility of final quantities levels to the subscriber.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This is the third post in a series explaining certain technical limitations with Quantity Manager.\u00a0 Today we\u2019ll cover something that affects all third-party tools for eBay.\u00a0 It is very likely that this is also an issue with all third-party applications that connect to any service through an API.\u00a0 In particular we\u2019ll be addressing the situation [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[4],"tags":[23,22,21,20,19,18,15,24],"class_list":["post-107","post","type-post","status-publish","format-standard","hentry","category-features","tag-api-access","tag-authentication-token","tag-ebay-third-party-tools","tag-inventory","tag-limitations","tag-not-a-bug","tag-quantity","tag-unsubscribing"],"_links":{"self":[{"href":"https:\/\/www.qtyman.com\/blog\/wp-json\/wp\/v2\/posts\/107","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.qtyman.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.qtyman.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.qtyman.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.qtyman.com\/blog\/wp-json\/wp\/v2\/comments?post=107"}],"version-history":[{"count":15,"href":"https:\/\/www.qtyman.com\/blog\/wp-json\/wp\/v2\/posts\/107\/revisions"}],"predecessor-version":[{"id":227,"href":"https:\/\/www.qtyman.com\/blog\/wp-json\/wp\/v2\/posts\/107\/revisions\/227"}],"wp:attachment":[{"href":"https:\/\/www.qtyman.com\/blog\/wp-json\/wp\/v2\/media?parent=107"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.qtyman.com\/blog\/wp-json\/wp\/v2\/categories?post=107"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.qtyman.com\/blog\/wp-json\/wp\/v2\/tags?post=107"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
