Seller Operations Software
High-performance software and automation tools for Amazon, Walmart, and multi-channel marketplace operations.
We built this software for our own store first
Ez Cloud started in 2013 by automating the parts of selling online that nobody wanted to touch — reimbursements nobody chased, inventory numbers nobody trusted, reports that took a person a day to assemble. We built the tools for that work, then other sellers asked for them.
Thirteen years later we’re an official Amazon Software Partner and a Walmart Approved Solution Provider, and marketplace operations is still the sharpest part of our engineering. These days we build the whole operational side for sellers — anything from a single integration to the system the business runs on.
The same five problems, every time
Once you’re past a few million in sales, the tools you started with stop keeping up and the gaps get filled by people doing manual work.
Whatever the operation needs
These are the areas we’re asked for most often, but the list isn’t the offer — we build to your process. If your problem isn’t here, it’s still probably something we’ve done.
Reimbursement recovery
Finds discrepancies the marketplace owes you for — lost and damaged units, fee errors, returns never restocked — and files the claims on a schedule instead of when someone remembers.
Inventory reconciliation
One figure everyone works from, checked across the marketplace, your warehouse or 3PL and your accounting, with the differences flagged rather than averaged away.
Profit intelligence
True margin per SKU, per channel and per order, with fees, storage, returns, ad spend and cost of goods in one place. Usually the first time an owner sees which products actually make money.
Multi-channel operations
Listings, pricing, stock and orders across every channel from one console, so adding a marketplace doesn’t mean adding a person to watch it.
Repricing & buy box logic
Pricing rules that follow your margin floors and your strategy, not a generic tool’s idea of them — including the products you’d rather not win at any price.
Integrations to your stack
SP-API, Walmart, eBay, Shopify wired into your ERP, WMS, carriers and accounting — with retries and logging, because these APIs fail and you need to know when.
Marketplace data has rules attached
Both marketplaces reviewed our security and our processes before letting us touch seller data. That review is the reason we can build on the official APIs instead of scraping screens.
Amazon Software Partner
Listed in the Selling Partner Appstore, developer audit passed.
Walmart Approved Solution Provider
Cleared to build and run seller-facing integrations.
When a subscription is enough
If a standard app covers what you need, use it. We’ll say so on the call — there’s no version of this where we recommend building something you can rent for a hundred dollars a month.
Custom starts making sense when your process isn’t standard: your own margin rules, your own warehouse logic, categories with unusual fee structures, or an operation big enough that the per-order pricing of a SaaS tool now costs more than owning the software. It also makes sense when the data has to reach your ERP and accounting properly rather than through a monthly CSV.
What you get either way is a fixed price, code you own, and tools that run in your own cloud account — including if you stop working with us.
