The 2026 marketplace problem

Selling on marketplaces costs more and forgives less.

These are the pressures hitting brands on Amazon, Walmart, and other channels right now. Which ones sound familiar?

01

Fees are eating your margin.

Referral cuts, fulfillment fees, inbound placement, low-inventory and storage charges stack up per unit. Lower-priced items can quietly turn unprofitable.

What we checkTrue profit per SKU after every fee.
02

Purchase orders stop with no explanation.

Vendors lose margin to chargebacks, co-op, and return allowances. When margin falls below a retailer's threshold, a product can be flagged CRaP and POs halt.

What we checkVendor margin leaks and chargeback root causes.
03

Your Buy Box disappears.

Marketplaces watch prices across channels. A discount from a retailer, a reseller, or your own site can suppress your offer somewhere else.

What we checkWhich source is breaking price parity.
04

You pay more just to defend your own brand.

Sponsored placements push organic results down and competitors bid on your branded terms, so ad costs climb without real growth.

What we checkAd spend that defends versus ad spend that grows.
05

Resellers and hijacked listings undercut you.

Gray market sellers break your pricing, and conflicting 1P and 3P edits can overwrite your approved content and variations.

What we checkUnauthorized sellers and listing control gaps.
06

Listings and payouts get blocked.

Verification and compliance checks, including documentation, labeling, and regional rules like GPSR and EPR, can trigger takedowns or held disbursements.

What we checkDocumentation and account verification gaps.

Your vendor and seller accounts are planned together, so a price move or listing edit on one side never wrecks the other.

03

Senior strategists, always

We stay deliberately lean. That means the person who audits your account is the same person managing it, with no junior hand-offs and no account churn.

04

A path into new markets

FAQs

Straight answers to common marketplace problems.

Why did Amazon stop sending purchase orders for my product?

One common cause is a product's profitability dropping below the retailer's internal threshold, often called CRaP (Can't Realize a Profit). Chargebacks, co-op allowances, and cost increases push margin down. Reviewing your vendor terms and unit economics shows where it is slipping and what can be done.

Why did I lose the Buy Box?

Price is the usual trigger. Marketplaces compare your price against other channels, and a discount from a retailer, a reseller, or your own site can suppress your offer. We trace which source is driving it and how to stop it.

Should I sell 1P, 3P, or both?

It depends on your margins, cash flow, and how much pricing control you need. 1P brings scale and less operational work but gives up pricing control. 3P gives you control but adds fees and logistics. Many brands run both, which only works when the two are coordinated. We manage both models, plus transitions from Vendor to Seller Central.

What kind of brands do you work with?

E-commerce brands of every size, from brands just launching to established sellers doing eight figures, on Amazon, Walmart, and other channels.

Do you work beyond Amazon?

Yes. Amazon is our deepest specialty, but we run full-funnel strategy across Walmart, Target, Best Buy, eBay, TikTok Shop, Shopify, and other major channels. We also help brands expand into new locales and marketplaces through our direct relationships, when the timing is right.

How do you measure success?

Against KPIs we agree on together: profitability, ROAS, and market share, tracked in a live reporting dashboard, not a monthly PDF.

What does an engagement cost?

Every partnership is scoped to the brand. After your free review, you'll get a proposal with clear pricing and deliverables. No surprises.
