By Karla Urdaneta, Operations Manager at ShipHouse. Karla's team receives, inspects, and restocks returns for ecommerce brands at our New Jersey and Delaware warehouses.
Reverse logistics is everything that happens after a customer sends a product back: authorizing the return, getting it to a warehouse, inspecting it, deciding what to do with it, and refunding the customer. For an ecommerce brand, it's where a sale either recovers its value or turns into a loss.
The numbers are large. The National Retail Federation and Happy Returns estimated that U.S. consumers would return $849.9 billion in merchandise in 2025, or 15.8% of retail sales. Online purchases come back more often, at 19.3%. Returns are a normal part of selling online. The question is how much of each return you get back.
This guide covers the returns process step by step, how warehouses grade returned items, what to do with each grade, the 2026 return rules on Amazon, Walmart, eBay, Shopify, and TikTok Shop, and the cost math behind each decision.
Reverse logistics vs. returns management
The two terms overlap, but they're not the same:
- Returns management is the customer-facing part: your return policy, the return portal, labels, refunds, exchanges, and store credit.
- Reverse logistics is the physical part: moving the item back, receiving it, inspecting it, and routing it to the right place. It also covers things that aren't customer returns, such as damaged goods, recalls, and unsold stock sent back from retailers.
A good returns program needs both. A generous policy without a fast warehouse process means refunded items sit in boxes losing value. A fast warehouse without clear policy rules means every return needs a judgment call.
The returns process, step by step
- Return request. The customer starts a return through your store, a return portal, or the marketplace. Your policy decides eligibility: the return window, condition rules, and excluded items.
- Authorization and label. The return gets an RMA (return merchandise authorization) number or a marketplace return ID, plus a prepaid label or drop-off instructions. The RMA is what lets the warehouse match the parcel to the order.
- Transit. The item travels back to your returns address. The closer that address is to your customers, the faster you can inspect and resell. Most U.S. online shoppers live east of the Mississippi, which is one reason brands use East Coast fulfillment.
- Receiving. The warehouse scans the parcel, matches it to the RMA, and records what actually came back. Wrong items, missing parts, and empty boxes get caught here.
- Inspection and grading. Each item is checked against your condition criteria and assigned a grade, ideally with photos.
- Disposition. Based on the grade, the item is restocked, repacked, refurbished, liquidated, returned to the vendor, donated, recycled, or disposed of.
- Refund, exchange, or credit. Depending on the channel, this happens before or after inspection (see the marketplace section below).
- Data. Return reasons and grades go back to the merchandising and product teams so the same returns happen less often.
How warehouses grade returned items
There's no industry-standard grading scale, so each brand defines its own. Here's the framework we use as a starting point with new clients:
Grade | Condition | Typical disposition | What you recover |
|---|---|---|---|
A: Like new | Unopened, or opened with tags, seals, and packaging intact | Restock as new | Full value |
B: Repackable | Unused, but packaging is opened, creased, or missing | Repack (new poly bag or box), then restock | Full value, minus repack cost |
C: Used or minor damage | Signs of use, missing accessories, or cosmetic damage | Refurbish, sell as open-box or B-stock, or return to vendor | Partial value |
D: Not resellable | Damaged, soiled, expired, or unsafe | Liquidate in bulk, donate, recycle, or dispose | Little or none |
Hold | Wrong item, possible fraud, or missing serial number | Quarantine and photograph for review or a claim | Depends on the outcome |
Your rules decide which category goes where. A cosmetics brand may treat any opened unit as Grade D for safety reasons, while an electronics brand may test and refurbish Grade C units. Write the rules down once, with photos of examples, so every return gets the same decision.
Disposition options
- Restock. The best outcome. The faster an item is back on the shelf, the more likely it sells at full price, especially for seasonal and fashion products.
- Repack. A new poly bag, box, or label turns many Grade B items into sellable stock at a small cost.
- Refurbish. Cleaning, testing, or replacing parts. Worth it for higher-value items.
- Secondary channels. Open-box listings, outlet sales, or B-stock marketplaces.
- Return to vendor. Defective items covered by a supplier agreement.
- Liquidate. Selling Grade C and D items in bulk lots at a fraction of their value.
- Donate or recycle. Keeps unsellable items out of landfill, and may have tax benefits.
- Dispose. The last resort, for unsafe, expired, or contaminated products.
Disposal is getting harder to justify. In the EU, large companies have been banned from destroying unsold clothing, accessories, and footwear since July 19, 2026. The U.S. has no equivalent rule as of late 2026, but brands selling in both markets increasingly use the same donate-or-recycle rules everywhere.
2026 return rules by sales channel
Each channel sets its own rules, and they decide when you lose the money and when you get to inspect the item.
Channel | Key 2026 return rules for sellers |
|---|---|
Amazon FBA | Amazon receives and handles returns at its fulfillment centers. Returns processing fees apply in some categories and for products above Amazon's return-rate thresholds. See FBA vs FBM. |
Amazon seller-fulfilled (FBM) | U.S. seller-fulfilled returns use Amazon's prepaid return label program. Amazon notified sellers that from December 18, 2026, they must upload a prepaid label within 7 days of a return request or issue a returnless refund; otherwise Amazon may refund the buyer and charge the seller. |
Walmart Marketplace (seller-fulfilled) | At least a 30-day return window, starting 7 days after the ship date. You need a U.S. return center (no P.O. boxes, Hawaii, Alaska, or territories), and you can't charge customers for return shipping. Refunds are issued at the first carrier scan, before you've inspected the item. See Walmart Fulfillment Services. |
eBay | Top Rated Plus listings need free returns for at least 30 days. A U.S. returns address makes that practical. See eBay fulfillment. |
Shopify | You set the policy. Customers can request returns from their account, and you approve them and send labels. See Shopify fulfillment. |
TikTok Shop | Buyers can request returns within 30 days by default. See TikTok Shop fulfillment. |
The pattern across marketplaces is clear: the refund often happens before the item is inspected. On Walmart, the money goes back at the first carrier scan. That makes inspection speed and good records more important, not less. If a return arrives empty or with the wrong item, photos and receiving records are what support a claim.
What a return really costs
Optoro, a returns technology company, estimates that processing a return costs on average 27% of the item's purchase price. That cost is made up of:
- The return label. Often paid by the seller, and on some channels required to be free for the buyer.
- Receiving and inspection labor. Opening the parcel, matching it, checking it, and taking photos.
- Materials. New poly bags, boxes, and labels for repacking.
- Lost value. Items that can't be sold as new, plus the price drop while stock waits to be processed.
- Fraud. NRF and Happy Returns estimate that 9% of returns are fraudulent, including empty boxes and swapped items.
When a returnless refund makes sense
Sometimes the cheapest return is no return at all. Compare the cost of bringing the item back with what you'd recover. In this illustrative example, return costs are $12 per item ($8 label + $3 handling + $1 repack):
$25 phone case (cost $6) | $120 jacket (cost $45) | |
|---|---|---|
Cost to bring it back | $12 | $12 |
Value if restocked as new | $6 in inventory | $45 in inventory |
Better choice | Returnless refund: the return costs more than the item | Process the return: you recover far more than it costs |
Returnless refunds work best for low-value, low-fraud-risk items. Set a dollar threshold, and cap how often a single customer can use it.
Return KPIs to track
KPI | What it tells you |
|---|---|
Return rate by SKU | Which products have sizing, quality, or listing problems |
Return reasons | Whether to fix the product, the photos, the size chart, or the packaging |
Dock-to-stock time for returns | How fast returns become sellable again |
Recovery rate | The share of returned value you get back |
Grade mix (A/B/C/D) | Whether returns are mostly resellable or mostly losses |
Exception rate | Wrong items, empty boxes, and missing parts that need a claim |
How to reduce returns at the source
The cheapest return is the one that never happens:
- Better product pages. Accurate size charts, measurements, and photos from several angles.
- Fit and use notes. "Runs small" or "best for" notes from customer reviews.
- Better packaging. Fewer items damaged in transit means fewer "arrived damaged" returns.
- Accurate picking. Shipping the wrong size or color creates returns that weren't the customer's fault.
- Exchanges first. Offering an exchange or store credit before a refund keeps the revenue.
Returns policy also affects sales. In the same NRF report, 82% of shoppers said free returns are a major factor in where they buy, and 71% said they're less likely to buy again after a bad return experience.
Should you outsource returns to a 3PL?
Many retailers already do. In the NRF and Happy Returns survey, 49% of retailers said they work with third-party logistics partners to handle holiday returns. Outsourcing makes sense when:
- Returns are taking space and staff time away from shipping new orders.
- Items sit unprocessed for days or weeks, losing value.
- You sell on several marketplaces with different return rules.
- You sell internationally and need a U.S. returns address.
A 3PL that also handles your outbound orders can restock returns into the same inventory pool, so a returned item can ship to the next customer the same week. At ShipHouse, returns are received, matched, inspected against the rules you approve, photographed, and routed to restock, repack, quarantine, or your chosen disposition, typically within 24 hours of arrival.

Frequently asked questions
What is reverse logistics in ecommerce?
Reverse logistics is the process of moving products back from the customer and deciding what happens to them: authorizing the return, shipping it back, receiving and inspecting it, then restocking, refurbishing, liquidating, or disposing of it.
What's the difference between returns management and reverse logistics?
Returns management is the customer-facing side, including the return policy, portal, labels, and refunds. Reverse logistics is the physical side: transport, receiving, inspection, and disposition.
What is the average ecommerce return rate?
NRF and Happy Returns estimated that 19.3% of online sales would be returned in 2025, compared with 15.8% of all retail sales. Rates vary widely by category, and apparel is usually higher.
How much does it cost to process a return?
Optoro estimates the average cost at 27% of the item's purchase price, including shipping, labor, materials, and lost value.
What is an RMA?
An RMA (return merchandise authorization) is a number assigned when a return is approved. It lets the warehouse match an incoming parcel to the original order and the reason for the return.
How do 3PLs grade returned items?
Most use a simple scale, such as A (like new), B (repackable), C (used or damaged), and D (not resellable), based on condition rules the brand approves. Each grade maps to a disposition.
What are the disposition options for returned inventory?
Restock, repack, refurbish, sell through secondary channels, return to the vendor, liquidate, donate, recycle, or dispose.
When should I offer a returnless refund?
When the cost of bringing the item back (label, handling, and repacking) is more than the value you'd recover, typically for low-cost items with low fraud risk.
How do Amazon's prepaid return labels work for seller-fulfilled orders?
U.S. seller-fulfilled returns use Amazon's prepaid return label program. Amazon notified sellers that from December 18, 2026, they must provide a prepaid label within 7 days of the return request or issue a returnless refund.
What are Walmart Marketplace's return rules for sellers?
Seller-fulfilled items need at least a 30-day return window starting 7 days after shipping, a U.S. return center, and free return shipping for customers. Walmart refunds the customer at the first carrier scan.
How fast should returns be restocked?
As fast as possible. Items lose value while they wait, especially seasonal and fashion products. Many 3PLs aim to process returns within 24 to 48 hours of arrival.
How do I reduce return fraud?
Match every parcel to its RMA, photograph contents on arrival, check serial numbers and seals, and set limits on returnless refunds per customer.
The bottom line
Returns are part of selling online, but losing money on them isn't. Clear grading rules, a fast inspection process, and a disposition plan for every grade decide how much of each return you recover. Marketplace rules that refund customers before inspection make speed and good records even more important.
