EU Customs Fees, Amazon Ad Budgets & Top Seller Mistakes

Leon joins as new co-host alongside Ali for a packed episode: the e-commerce news that actually matters this month, the questions brands ask most before launching on Amazon, and the mistakes that cost sellers the most money and time.

In this episode: Ali Shariat and Leon Rymer cover global e-commerce trends, new EU customs fees, Amazon's AI cost pressures, and the most common questions and mistakes from real seller accounts.

Key takeaways

Global e-commerce grew 9.5% year-on-year in June, partly driven by Prime Day shifting into June and general "excuse to buy" momentum from World Cup season.
The EU's new de minimis exemption removal adds a €3 fee per customs classification per parcel, aimed at Temu, Shein and AliExpress, but small and medium sellers shipping single orders will feel it too. Sending stock into Amazon or a 3PL warehouse avoids it.
The UK has moved its own de minimis relief end date forward to October 2028, still later than the US and EU, meaning the UK stays an open target for low-value imports in the meantime.
Amazon and Anthropic are renegotiating pricing from compute-based to token-based, which could squeeze Amazon's margins and, historically, cost pressure on Amazon has meant slower seller disbursements.
For ad budget when starting from scratch, expect to spend 20-30% of revenue on ads while entering a category, dropping as organic rank builds. Budget off your revenue target, not a fixed ad number.
Don't expect to break even before month six, and budget stock, ads, and inventory replenishment as three separate pools from day one.
Get a trademark before launch. Without one you can't get Amazon Brand Registry, which controls how your listings can be edited and protected.
The most expensive recurring mistakes: driving traffic to unoptimised listings, running out of stock (the single most common issue seen across all client accounts), treating a forecast as fixed instead of updating it weekly, and assuming a retail pack format works for Amazon fulfilment without adjustment.

The detail

What ad spend to expect when starting from scratch
Most sellers ask what ACOS or monthly ad spend to expect, but the more useful number is TACOS, total ad spend divided by total revenue, since ACOS alone only judges individual campaigns. As a rule of thumb, expect to spend 20-30% of revenue on ads while entering a category, since you're buying visibility you don't have yet. That percentage should fall as Amazon's organic ranking rewards consistent sales, shifting weight away from paid. Budget should start from a revenue target and work backwards to an ad percentage, not the other way round. For the full breakdown of TACOS benchmarks by category, see What's Actually a Good TACOS?

How long until you break even
Sales stay low until ads are switched on, and even then they build gradually. Don't expect to break even on monthly sales before around month six, with overall break-even (covering the early loss-making months) taking longer still. Budget for this in three separate pools from day one: stock, ad spend, and replenishment, since relying on future sales to fund any of the three is where accounts run into trouble. It's also common for someone outside the Amazon side of the business, an accountant or bookkeeper looking only at monthly figures, to flag a "loss" that's actually just the expected early curve, so keep the full picture in view before reacting.

The stock and forecasting mistake that costs the most
Running out of stock is the single most common issue seen across client accounts. Amazon will search-suppress listings with less than roughly 3 days of stock cover in the UK or 45 days in the US, so aim to hold 6-8 weeks of cover at all times. Forecasts should inform production orders, but they're a starting estimate, not a fixed promise, they need weekly review and adjustment as real sales data comes in, especially with long manufacturing lead times of 3-4 months. Shelf-life products carry an extra trap: Amazon won't accept stock with less than 105 days of shelf life remaining, and will stop selling stock once it drops under 45 days remaining, even if it's already in the warehouse.

Matching pack format to how Amazon customers actually buy
Retail shelf-ready packaging (designed for a human stacker to shelve) isn't the same as pack formats that make sense for an online buyer, or packaging that survives Amazon's pick, pack and post process. A 12-pack might suit a supermarket shelf but not a first-time online buyer, who's more likely to try a mixed variety pack first, often 60-80% of early sales come from exactly that. Build "ship-ready" packaging and a trial-size mixed pack into the launch plan rather than assuming retail formats transfer as-is.
