Know what you actually made — on every SKU, in every marketplace.
MeshMargin joins your Amazon and eBay data into one mesh and reconciles every cost against every sale: referral and FBA fees, inbound shipping, ad spend, refunds, and your COGS. What's left is the number that matters — your true margin per SKU.
- Built for sellers whose listings span Amazon US, Canada, Japan, and eBay — not just one storefront.
- Read-only API access through Amazon SP-API and the eBay Sell API. Disconnect anytime.
- Designed by a multi-marketplace seller, after one too many profit reports that didn't survive a second look.

The problem
Your profit tools are reading your business wrong.
Most margin dashboards were built for a single storefront in a single country. Sell across borders and marketplaces, and the numbers quietly stop meaning anything.
Zero stock that isn't zero
With Remote Fulfillment with FBA, your Canada or Mexico listing draws on your US inventory pool — there is no local stock to count. Tools that read local inventory report 0 and call the listing dead while buyers are still ordering. MeshMargin models the shared pool, so availability and margin reflect how the listing actually sells.
Fees scattered across every report Amazon and eBay publish
Referral fees in one file, FBA and inbound shipping in another, ad spend in a separate console, refunds somewhere else — and eBay's final value and promoted-listing fees in a different world entirely. Stitching that together in spreadsheets is a monthly chore, and it's stale the day you finish it.
A healthy store average, sick SKUs underneath
A blended 22% margin can hide a SKU losing money on every order once ads and shipping land. Decisions — reprice, restock, discontinue — happen at SKU level. Your profit view should live there too, per marketplace, in one currency.
How it works
Mesh first. Margin second.
The mesh is the join: every marketplace, fee type, and currency normalized into one ledger per SKU. The margin is what falls out of it — no spreadsheet archaeology.
Connect your marketplaces
Authorize Amazon (SP-API) and eBay (Sell API) with read-only access. MeshMargin pulls orders, fees, settlements, inventory, and ad spend automatically — including remote-fulfillment listings that share one inventory pool.
The mesh reconciles everything
Fee types are mapped to a single cost model, currencies converted, and your COGS attached per SKU. Every dollar a marketplace kept is accounted for against the sale that caused it.
Act on true margin
See per-SKU, per-marketplace margin you can defend. Spot losers early, reprice with the full cost picture, and restock the SKUs that actually pay for the shelf.
What we're building
The profit view multi-marketplace sellers actually need.
MeshMargin is in active development. Waitlist members get early access as each piece ships — and a direct line to the roadmap.
True per-SKU margin
Revenue minus every marketplace fee, shipping cost, ad dollar, refund, and COGS — per SKU, per marketplace, per period.
One mesh across marketplaces
Amazon US, Canada, and Japan plus eBay in a single view — no more reconciling four dashboards that each tell a different story.
Inventory truth for shared pools
Remote-fulfillment and cross-border listings modeled the way they really draw stock, so “zero” only shows when it's actually zero.
Currency, normalized
USD, CAD, and JPY results rolled into the reporting currency you choose, with the original figures one click away.
Negative-margin alerts
The week a SKU slips underwater — a fee change, a creeping ad cost — you hear about it, not at quarter-end.
Exports your accountant will accept
Clean per-SKU P&L exports that tie back to marketplace settlements — built to be checked, not just admired.
Exploring next — margin-gated ad guidance. Once MeshMargin knows a SKU's true landed margin, it can say how much that SKU can actually afford to bid. We're exploring an ads-intelligence add-on that caps suggested bids at what the margin supports — no more campaigns that “work” on ROAS and lose money on every order.
Early access
Join the waitlist.
Early access rolls out to the waitlist in small batches as the Amazon and eBay connections come online. Tell us where you sell and what your current profit reports get wrong — it directly shapes what ships first.
No spam, no list-selling, ever. One email when your batch opens, and occasional development updates you can opt out of with one click.
You're on the list.
Thanks for joining. We'll email you when your early-access batch opens — and if you described a reporting headache, it's already on the roadmap wall.
Questions
Before you ask.
When does MeshMargin launch?
It's in active development now. Rather than a big-bang launch, early access opens in small batches to waitlist members as the Amazon and eBay connections are completed — join the list and you'll hear as soon as your batch opens.
Which marketplaces are supported first?
Amazon — including multi-marketplace setups like US + Canada + Japan and Remote Fulfillment with FBA listings — and eBay are the launch connections, because that's where the margin picture is most fragmented today.
I already use a profit dashboard. Why switch?
If your current tool reads your business correctly, don't. MeshMargin exists for the cases the incumbents get wrong: shared inventory pools that report as zero stock, fees split across disconnected reports, and store-level averages that hide losing SKUs. If that sounds familiar, you'll feel the difference in the first sync.
How does MeshMargin access my seller data?
Through the official Amazon SP-API and eBay Sell API, with read-only authorization you grant and can revoke at any time from your seller account. MeshMargin never asks for your seller password.
What will it cost?
Pricing isn't final yet — it will be set with early-access members, and waitlist members will hear the founding pricing before anyone else.
