Every warehouse has a bad week. When the same problems keep coming back on your devices and your current partner can't fix them, it's time to look for a new one.
It's time to switch electronics fulfillment partners when the same problems keep coming back after you've raised them. Five come up most often for device brands:
A single miss happens anywhere. A problem that repeats, and that your partner can't fix, is the reason to move.

Every 3PL has off days. A carrier runs late, a storm closes a road, a count comes up wrong once. Switch over one incident and you take on a move and a new set of unknowns to escape a problem that may never come back. What matters is whether the same failure keeps happening on the same SKUs, and whether your partner can name a fix and make it last.
Electronics carry batteries and serial numbers, cost a lot per unit and come back often. Each of those gives a weak warehouse a place to slip, and device brands tend to see the same few failures again and again. Once they start repeating, you're looking at more than bad luck.
Judge each one by how your current partner performs for you.
Lithium batteries are Class 9 dangerous goods, and a partner that classifies them wrong often gets your parcels refused or charged extra. Shipping a power bank as if it were equipment is one of the most common mistakes. The fix is to record every battery SKU's UN number and watt-hour rating, then ship it by ground or air to match. Battery classes are explained under power bank and charger fulfillment, and the small electronics fulfillment overview covers each kind of device.
Warranty, activation and dispute questions usually come back to a device's serial number. If your partner can't show you which unit left on which order, a warranty claim or a friendly-fraud dispute gets much harder to settle. A sound setup records the serial at receiving and scans it again at pick and pack; serial number tracking and warranty fulfillment has the detail.
Electronics cost a lot per unit, which makes them a target for theft and for costly miscounts. A partner that keeps devices on open shelves and never counts them between annual inventories takes that loss straight out of your margin. If your counts keep coming up short and nobody can say where the units went, the controls are what's failing. Look for access-controlled storage, cycle counting and a scanned pick, each described in high-value and theft-sensitive fulfillment security.
When returned devices pile up in a corner, your money sits there with them. A returned device can't simply go back on sale. Someone has to inspect and grade it first, and a partner that never gets to it is costing you every week. We receive each return against its original order, inspect it, and restock what can sell or send the rest on by your rules, so the money in a returned unit is recovered where it can be, and the rest stops taking up space. Testing, repair and refurbishment go deeper, and are worth raising at the start. The steps are laid out in electronics returns, RMA and reverse logistics, and the service itself is returns and reverse logistics.
Some partners make you email and wait to learn what's on hand, how many units of each serialized item you hold, or where an order stands. That leaves you running the business without its own numbers, and with expensive, serialized stock the gap costs real money. We run every service on BestOMS, with Deposco behind it and Dropstream handling the channel connections, so you see your orders and inventory on one platform. For more, see our technology platform and our distributed fulfillment network.
Most of the risk in switching sits in the handover. Expensive, serialized stock has to leave one building and arrive in another counted, correct and matched to its serials. A gap along the way can strand orders, or break the link between a serial and its order that you'll need for a warranty claim later.
The safe way to move is a reconciled transfer. Your stock is received and counted in. Serials are captured where your program tracks them. The count is checked before any order goes to the new building. That way the count and the serial records that go into inventory are the same ones used to pick.
After that, orders from your site, your marketplaces and retail come in through BestOMS without anyone typing them in again. You can split your stock across several of our warehouses, and from them, ground service reaches 99.77% of the US in 1-3 days.
Before the first order, have the watt-hour rating and UN number ready for each battery SKU, and confirm the lithium-shipping and hazmat scope for those SKUs with our team. Some brands move every SKU at once. Others stage the move around a launch or a peak. We plan the timing with you around your catalog.
Each of these is easy to take for granted and costly to get wrong, so check it against what the partner actually does.
No set number decides it, but a pattern counts for more than any one miss. One problem that your partner admits and fixes is a working relationship doing its job. Two or more that keep coming back on the SKUs that earn your revenue, after you've raised them, make the case for moving.
Staying has a cost, and you pay it again every month until the partner changes:
Before you pick the next partner, work through our questions to ask an electronics 3PL with whoever you talk to. For how devices are handled from receiving through returns, see small electronics fulfillment.
When the same problem keeps coming back after you've raised it, and your partner can't fix it. Every warehouse has a bad week now and then, and one bad week isn't a reason to move. A miss that repeats on the same SKUs is. For device brands the repeat offenders are battery parcels refused or surcharged at the carrier, serial or IMEI records too thin to trace a warranty claim or dispute, expensive stock that keeps shrinking, returns left ungraded for weeks, and theft-prone devices stored with no security controls.
Five come up again and again for device brands. Battery products get refused or surcharged on air because they were classified wrong. Serial or IMEI records have gaps, so warranty and dispute questions are hard to answer. Expensive stock shrinks and nobody controls who can reach it. Returns pile up without being graded. And you can't see your serial-level stock without asking for it. Each of these comes from how the warehouse works rather than from bad luck, which is why they keep happening until the partner changes.
Usually because the battery was classified wrong. Lithium batteries are Class 9 dangerous goods, and the carrier checks how each one is labeled. Cells and batteries shipped alone are UN3480 or UN3090, batteries in or with equipment are UN3481 or UN3091, and a power bank counts as a battery, not equipment. What can fly depends on the watt-hour rating and the charge level. By air the excepted limit is 20 Wh per cell and 100 Wh per battery, and lithium-ion has to be at 30 percent charge or less. Highway and rail shipments can carry up to 300 Wh per battery, on a package marked forbidden aboard aircraft and vessel. Before you move stock, find out from us what our hazmat and lithium shipping covers.
The move itself is where the risk sits, so it should be done as a counted, checked transfer. Your stock is received and counted in. Serials are captured where your program tracks them. The count is checked against what was shipped before any order goes to the new building. With us, orders run on BestOMS with Deposco behind it, and you can spread inventory across several of our warehouses, which together reach 99.77% of the US in 1-3 day ground. Talk to our team about the timeline for your SKU and serial count.
Start with hazmat and lithium scope. Ask whether the partner classifies batteries by UN number and watt-hour, and what it can actually ship by air. Then ask how deep its serial tracking goes. Capture and match before shipping is the minimum, and if you need activation or data-wipe, ask whether it does those. Next, find out whether its returns work stops at inspect, grade and route, or goes on to function testing and refurbishment. Last, check the security controls on high-value stock. We'll answer all four for your catalog.
We receive incoming stock against each SKU and count it in, capturing serials where your program tracks them. That way the count that goes into inventory is the count we pick from. Your sales channels connect to BestOMS through Dropstream, so orders arrive without anyone typing them in again. You can place stock across several of our warehouses, so the first orders ship from the one nearest each customer. We'll build the migration plan for your catalog with you.
