Common Problems Faced by Beginner Sellers
The problems that actually sink new Amazon sellers are rarely the ones they were worried about — and a few of them got materially worse in 2026.
Updated September 1, 2026. Updated for 2026: the 75-character title cap, the New Selection programme launched 30 July 2026, and the January 2026 FBA fee increases that changed the maths on low-price items.
New sellers usually arrive worried about the wrong things. Sourcing and ads get all the attention; the things that quietly end businesses are duller than that.
The policies are not the problem — the enforcement timing is
Most sellers do not fall foul of an exotic rule. They fall foul of a routine one at the worst possible moment, and discover that the appeal takes weeks.
Two 2026 changes worth knowing before they bite:
Title compliance. Since 27 July 2026 titles are capped at 75 characters including spaces, in all categories except Media. Amazon has said it will replace non-compliant titles with its own generated versions, with a review window for brand owners. If you launched on a template from 2024, your titles are already over.
On-time delivery enforcement. From 28 February 2026 Amazon moved to targeted deactivation for OTDR failures rather than blanket account freezes — more surgical, but it means specific high-volume listings can go dark while the rest of the account looks fine. If your best SKU stops selling and you cannot see why, check the metric before you blame the algorithm.
The practical defence is boring: read the Account Health dashboard weekly, not when something breaks.
Choosing a product on the wrong criteria
Most beginner product research optimises for demand and ignores return rate, unit economics after fees, and whether the item can survive being posted.
FBA fees rose on 15 January 2026 — an average of about $0.08 per unit, with steeper increases on low-price items; small standard units under $10 saw around $0.12. That does not sound like much until it is a third of your margin.
The related trap is returns-heavy categories. Apparel and footwear picked up additional return processing fees in February 2026, on top of already carrying the highest return rates on the platform. A product with a 4% margin and a 25% return rate is a hobby with paperwork.
If you are starting now, there is one genuinely useful programme: the New Selection benefits that took effect on 30 July 2026 — reduced referral fees on early units of new-to-FBA products, coupon and Vine credits, and a window of free storage and returns. It is worth reading before you send your first shipment rather than after.
Inventory: the two ways to get it wrong
Too little and you go out of stock, lose ranking momentum, and spend months recovering a position you had already paid to build.
Too much and you pay storage on inventory that is not moving — and note that from 1 March 2026 removal and disposal fees are charged per unit processed rather than on order completion, which changes when the cash actually leaves.
There is no clever answer. There is only knowing your lead time honestly and reordering before you feel like it.
The listing they build once and never look at again
This is the one we see most, and the one closest to our own work, so weigh it accordingly.
A new seller builds a listing during launch week, when they are busy and stressed, using whatever photography the supplier sent. It converts badly. They respond by increasing ad spend, which buys more traffic for a listing that was already failing to convert — so the loss just gets bigger and faster.
Three checks worth more than a week of ad tinkering:
- Look at your main image at thumbnail size on a phone. Not on your monitor. If you cannot tell what it is at that size, nothing else in the gallery matters.
- Is there a size reference anywhere? If not, expect returns from people who imagined something different.
- Does the title still fit in 75 characters, and does it say what the thing is? A great many do not, since the cut lands mid-word.
Doing everything at once
The last one is not an Amazon problem. New sellers try to run ads, build a brand, expand the catalogue and open a second marketplace simultaneously, and do all four badly.
One product, listed properly, that converts and does not come back, teaches you more than five that are all slightly broken. It is also the only version of this that is still enjoyable a year in.
