Most FBM fulfillment pages read like they were written by someone who never packed a box. This one is written by someone who has.<\/p>\n<p>I&#39;ve been selling on Amazon for about ten years, and I co-run 365PrepCenter with Oleg, who runs the floor day to day. When we started offering FBM fulfillment alongside our prep work, the thing that surprised sellers most wasn&#39;t the pricing &mdash; it was how much of FBM fulfillment is just discipline around timing and inventory accuracy. There&#39;s no Amazon inbound plan to fall back on. If an order goes out wrong, it&#39;s on you, not a warehouse queue.<\/p>\n<p>So this article isn&#39;t a sales pitch. It&#39;s what we actually do when an order lands in our queue, what it costs, and where sellers usually get tripped up switching from doing it themselves or from another 3PL.<\/p>\n<h2>How FBM Order Flow Actually Works at Our Warehouse<\/h2>\n<p>Orders come in through your Amazon Seller Central, Shopify, Walmart, TikTok Shop, eBay or Etsy account &mdash; the same floor, the same rates, regardless of channel &mdash; and we pull them on a schedule tied to our cutoff: 11:59 AM, Monday through Friday. Anything received before that cutoff ships same day. Anything after rolls to the next business day. This isn&#39;t a marketing number; it&#39;s how our pick-pack team structures the morning. Tatiana, who handles most of the physical pick-pack work, starts pulling orders around 9 AM so there&#39;s a buffer before cutoff for anything that needs a second look &mdash; mismatched SKU, damaged unit, low stock flag.<\/p>\n<p>What the per-order rate covers: pick, pack into a 13&times;15&quot; polymailer (or a box where the product needs one), carrier label, and handoff to USPS, UPS or FedEx the same day. Package weight limit is 25 lbs.<\/p>\n<p>Pricing depends on your daily order volume, which matters more than most sellers expect:<\/p>\n<ul>\n<li>10 or more orders per day &mdash; $2.00\/order<\/li>\n<li>Under 10 orders per day &mdash; $2.50\/order<\/li>\n<li>Each additional unit in the same order &mdash; +$0.30<\/li>\n<li>Oversized or fragile orders &mdash; from $2.50, depending on what the packing actually takes<\/li>\n<\/ul>\n<p>If you&#39;re doing 6 orders one day and 14 the next, we price on your actual daily average, not a strict per-order lookup &mdash; worth asking about directly if your volume swings seasonally.<\/p>\n<p>One detail specific to Amazon FBM: for orders sold on Amazon, we buy labels through Amazon Buy Shipping. That keeps the shipment inside Amazon&#39;s own protection against A-to-Z claims and keeps your on-time delivery metrics clean. Orders from your other channels ship on standard carrier rates.<\/p>\n<p>There&#39;s no setup fee and no long-term contract, which matters if you&#39;re testing a new sales channel and don&#39;t want to commit to a 12-month 3PL agreement before you know if the channel even works.<\/p>\n<h2>Where FBM Fulfillment Breaks Down (and Why It&#39;s Usually Not the 3PL&#39;s Fault)<\/h2>\n<p>Most fulfillment problems we see aren&#39;t packing errors. They&#39;re inventory sync issues. A seller&#39;s storefront says 40 units in stock, our floor count says 12, and nobody caught the gap until an order got backordered.<\/p>\n<p>This is why every client gets their own login to Ysell.pro, the WMS platform we run the warehouse on &mdash; real-time inventory counts, cubic footage and storage cost visible 24\/7, not a weekly email update. Ysell isn&#39;t our software; it&#39;s a platform built by Fulfillmentbox that we use and give our clients access to, and it&#39;s also where your FBA shipments get created when you&#39;re running both models. If you want the full walkthrough of setting it up, our<a href=\"https:\/\/365prepcenter.com\/ysell-guide\">&nbsp;<\/a><a href=\"https:\/\/365prepcenter.com\/ysell-guide\">Ysell login guide<\/a>&nbsp;covers it step by step.<\/p>\n<p>The second thing that trips sellers up is storage assumptions. The first 7 days after receiving are free&nbsp;&mdash; that&#39;s a landing window so inventory can be counted, measured and put away before the meter starts, not a monthly freebie. After that it&#39;s $1.00\/cubic foot per month or $40\/pallet per month, depending on how your goods are stored. Storage is always billed by volume, never by box count, and there are no volume discounts on it &mdash; the rate is the rate.<\/p>\n<p>Receiving is separate and small: $0.10\/unit&nbsp;if we&#39;re storing the goods for you, free&nbsp;if the shipment is going straight out to Amazon FBA without storage, or $25\/pallet&nbsp;for palletized inbound. Pallets get received on the floor and measured before anything goes into rotation, so the cubic footage in Ysell reflects what&#39;s actually sitting there, not an estimate.<\/p>\n<p>Returns&nbsp;are the other place FBM differs sharply from FBA. When a customer sends something back to your storefront&#39;s return address, we process it at $1.50\/unit for small and standard items&nbsp;and $3.00\/unit for oversized goods&nbsp;&mdash; inspecting condition, confirming it matches the original order, grading it New \/ Used \/ Garbage, and flagging what goes back into sellable inventory versus written off. Disposal is free for up to 10 units; beyond that it&#39;s $15 per box.&nbsp;If you&#39;re running FBM alongside FBA removals, it&#39;s worth reading how<a href=\"https:\/\/365prepcenter.com\/amazon-prep-center-pricing\">&nbsp;<\/a><a href=\"https:\/\/365prepcenter.com\/amazon-prep-center-pricing\">FBA removals processing<\/a>&nbsp;works separately, since receiving and inspection are handled differently there.<\/p>\n<p>One thing to know upfront: returns and removals processing come as part of our prep and fulfillment service. We don&#39;t take them on as a standalone contract for inventory we don&#39;t otherwise handle.<\/p>\n<h2>The Hybrid Setup Most Growing Sellers End Up With<\/h2>\n<p>Sellers rarely stay pure FBM or pure FBA. The setup that works best for most of the accounts we run: keep the bulk of your inventory with us, ship FBM from here, and send small replenishment batches into FBA &mdash; 100 to 200 units at a time. You cut Amazon&#39;s storage fees, you stop paying for slow-moving units sitting in their network, and you still have depth on the shelf so an FBA stockout doesn&#39;t put you out of stock on the listing. If you&#39;re testing a new SKU or a new season, this is usually the cheaper way to find out whether it moves.<\/p>\n<h2>What We Won&#39;t Do, and Why That Matters<\/h2>\n<p>We don&#39;t take large furniture, anything frozen or requiring refrigeration, or lithium batteries. Hazmat is case by case &mdash; ask before you ship it. This isn&#39;t a legal disclaimer buried in fine print; it&#39;s a real limit on our 1,200 sq ft climate-controlled space in Lebanon, Ohio. We&#39;d rather tell a seller upfront that we&#39;re not the right fit than take on inventory we can&#39;t store or ship safely.<\/p>\n<p>Everything else &mdash; food (ambient, shelf-stable), cosmetics, supplements, electronics, apparel, oversized palletized goods &mdash; we handle across Amazon FBA and FBM, Shopify, Walmart, TikTok Shop, eBay and Etsy from the same facility.<\/p>\n<h2>FAQ<\/h2>\n<p>How fast will my FBM orders actually ship?&nbsp;Same day, if the order is in our system before the 11:59 AM cutoff, Monday through Friday. Anything after that ships the next business day. This is a hard cutoff tied to our pick-pack schedule, not a rough target.<\/p>\n<p>What does FBM fulfillment cost?&nbsp;$2.00 per order at 10 or more orders a day, $2.50 per order below that, plus $0.30 for each additional unit in the same order. Oversized and fragile orders start at $2.50. Full rates are on our<a href=\"https:\/\/365prepcenter.com\/amazon-prep-center-pricing\">&nbsp;<\/a><a href=\"https:\/\/365prepcenter.com\/amazon-prep-center-pricing\">pricing page<\/a>.<\/p>\n<p>How do I get set up with Ysell to track my inventory?&nbsp;Once you complete intake, you get your own login and personal ID at Ysell.pro, typically the same day. If it&#39;s been longer than 24 hours and you haven&#39;t received credentials, reach out directly &mdash; usually it&#39;s a step in intake that got missed, and we resolve it within 24&ndash;48 hours.<\/p>\n<p>Do you charge extra for storage in the first week?&nbsp;No &mdash; the first 7 days after we receive a shipment are free. After that it&#39;s $1.00 per cubic foot per month, or $40 per pallet per month, based on how your inventory is stored. Storage is billed by volume, not by number of boxes.<\/p>\n<p>What happens to returned items on FBM orders?&nbsp;Returns get inspected against the original order, graded New \/ Used \/ Garbage, and either restocked or flagged. $1.50\/unit for small and standard items, $3.00\/unit for oversized. Disposal is free up to 10 units, then $15 per box.<\/p>\n<p>Is there a contract or setup fee to start?&nbsp;No setup fee and no long-term contract. A $50 minimum monthly charge applies once your account is active. You pay for the work we do.<\/p>\n<p>Do you only work with Amazon sellers?&nbsp;No. FBM is the Amazon-specific term, but the same pick-pack operation runs Shopify, Walmart, TikTok Shop, eBay and Etsy orders at the same rates from the same building.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>&nbsp;FBM fulfillment explained by an Ohio prep center operator: same-day cutoff, real pricing, order flow, storage and returns &mdash; and what to check before you switch 3PLs.<\/p>\n","protected":false},"author":1,"featured_media":346,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[5],"tags":[],"class_list":["post-347","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-fbm-fulfillment"],"_links":{"self":[{"href":"https:\/\/365prepcenter.com\/blog\/wp-json\/wp\/v2\/posts\/347","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/365prepcenter.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/365prepcenter.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/365prepcenter.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/365prepcenter.com\/blog\/wp-json\/wp\/v2\/comments?post=347"}],"version-history":[{"count":0,"href":"https:\/\/365prepcenter.com\/blog\/wp-json\/wp\/v2\/posts\/347\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/365prepcenter.com\/blog\/wp-json\/wp\/v2\/media\/346"}],"wp:attachment":[{"href":"https:\/\/365prepcenter.com\/blog\/wp-json\/wp\/v2\/media?parent=347"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/365prepcenter.com\/blog\/wp-json\/wp\/v2\/categories?post=347"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/365prepcenter.com\/blog\/wp-json\/wp\/v2\/tags?post=347"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
