Frequently asked questions

Seller 365 runs your whole workflow — sourcing, listing, repricing, feedback, and profit tracking — from one account instead of a stack of separate logins. It also recovers money Amazon owes you automatically, and for brands, keeps you selling across every channel from one place.
Reseller plans start at $69/month, Brand plans at $179/month. Every plan includes full access to all tools for your model — the difference between tiers is scale (seats, limits, support), not features.
Seller 365 includes core versions of both — reimbursement recovery on every plan, multichannel selling as an add-on (Reseller) or built-in (Brands). If either is your primary need rather than a piece of a bigger workflow, UniCon and Margin Pro serve that at a dedicated level.
Start your free trial directly from this page — no sales call required. You'll get 7 days instantly, with 7 more unlocked when you connect your Amazon Seller Pro account.
Every plan includes industry-leading support. Pro adds premium support with under-30-minute response times.
You'll get a heads-up before you hit a cap, and can upgrade to the next tier at any point — there's no service interruption or hard cutoff. Need more seats without changing tier? Additional users are $15/mo each on Reseller Teams and Pro and on every Brands plan (Reseller Standard is single-user).

As Acquco scaled across channels and geographies, margin leakage piled up across marketplace fees, inventory discrepancies, and international shipping contracts. Margin Pro recovered the fees and discrepancies automatically, renegotiated the shipping contracts, and optimized supplier yield.

“Protecting margin is a continuous discipline, not a one-time initiative.”

Wiley ZhangCOO, Acquco

MinimalInternal effort

With over $50M in annual logistics spend, even small inefficiencies compounded into serious lost margin. Margin Pro benchmarked Grainger's contracts against industry data and renegotiated agreements across every service level – without switching a single carrier.

“Large logistics budgets magnify the impact of small inefficiencies.”

Bryan MeyersDirector of Global Logistics, Grainger
$3.5MAnnual savings
Rock-SolidAgreement quality

Amerex had already negotiated strong carrier rates – but in fashion, shipping costs erode margin fast even after the first win. Margin Pro became a long-term extension of their logistics team, re-examining contracts every cycle to keep stacking savings.

“Initial optimization does not eliminate future margin leakage.”

Even with existing audit processes in place, Celsius was leaving money on the table across a fast-growing marketplace footprint. Margin Pro's automated audit surfaced leakage across fees, inventory, and chargebacks – recovered fast, with almost no internal lift.

Stadium Goods needed a massive catalog live on Walmart Marketplace before peak season, with zero tolerance for listing errors or oversells. CedCommerce's accelerated onboarding and real-time sync got the full catalog live and selling immediately.

“Real-time synchronization is non-negotiable for large-scale inventories.”

For Rebag, every handbag and jewelry piece is one-of-a-kind — a single oversell breaks the authenticity promise buyers pay premium prices for. CedCommerce's real-time sync and embedded trust signals kept 25,000 unique items accurate across every channel.

“Luxury resale depends on credibility and operational precision.”

As David Protein scaled its Amazon FBM operations, order data inconsistencies were creating fulfillment bottlenecks and eating up manual audit time. CedCommerce's dedicated sync infrastructure closed the gap and eliminated the manual work entirely.

“Operational precision is not optional — it is foundational to growth.”
