The platform

One operating layer over every marketplace you sell on.

Unison sits across your channels as a single system of record, with a command layer on top. Three jobs: connect, unify, operate.

01 · Connect

Plug in the marketplaces, once.

We install dedicated, permissioned connections into each channel you sell on: Shopify, Amazon, Walmart, Faire, WooCommerce, eBay, Etsy, TikTok Shop, and the ones after those. You authorize once. We own the API plumbing, rate limits, and token refreshes.

Read and write: listings, price, and inventory, on the marketplaces themselves.
Runs in the background. No window has to stay open for a launch to finish.
Scoped per marketplace. You see exactly what is granted, and you can revoke it.
02 · Unify

One record of the product. Yours.

Every marketplace lands in one database that belongs to you. Orders, catalog, inventory, payouts, and the price history behind them. The same SKU across channels becomes one row, with current state and the full trail.

Reconciled: one product, however many listings it has.
Historical: today's numbers, and the month you will ask about later.
Yours: exportable any time. We are the operator, not a data landlord.

Question it. Command it.

Ask in plain language and get the answer from your marketplaces, one channel at a time when the question is about all of them. Give an instruction and it writes back, with a reason, a captured before-state, and one-step rollback.

Answers: growth last month, margin by SKU, which channel is out of cover.
Actions: launch this item, raise this price, hold a listing that fails the band.
The same leash everywhere: a change that is fine on Shopify is still checked before it hits Walmart.
One channel
“Launch the Aurora Candle everywhere.”
“How much did we grow last month?”
“Raise Aurora to $34.99 on every channel.”
“Which SKUs are under 20 days of cover?”
“Rewrite this listing for each marketplace.”
The operating loop

A system that gets sharper every week.

SENSE

Daily guards

Each morning it checks price drift, days of cover, and listing errors against your baselines.

ACT

Proposals and approvals

It proposes the fix, or applies it inside your bands. You choose what is automatic and what waits.

LEARN

Scored changes

Every price and listing change keeps its baseline and is scored days later, on your catalog.

The record

The record Unison keeps.

Five parts of the business, kept current, with the trail behind each one. The database belongs to you.

Orders

Every order, named by marketplace, SKU, and the day it landed. Fourteen months stay available to ask about.

Catalog

One row for the SKU. Each marketplace listing stays on that row, with its own title and price.

Inventory

On hand, reserved, and days of cover, from live sales. The morning cover check reads this number.

Payouts

Fees, net, and the marketplace that paid. Margin by SKU keeps the fee beside the deposit.

Listings

Title, price, and stock as they sit on the channel now, and the value from before the last change.

Read and write

Read access, and the write that goes live.

Read is orders, catalog, inventory, and payouts. A write is a listing, a price, or stock, and it stays inside the band the brand set.

Read

Orders, catalog, inventory, and payouts. Ask in plain language and the answer comes from this record. The listing on the marketplace stays as it is.

Write

A listing, a price, or stock. It goes live on the marketplace, inside the band the brand set, with the prior value saved.

The leash is on security & control. Schedule a call and we will walk a read and a write on your catalog.

On each marketplace: Amazon, Walmart, Faire, Shopify, WooCommerce, eBay, Etsy, and TikTok Shop.

Retail channels, inventory systems, ERPs, and shipping tools sit on the same record when they have an API or an MCP server. The full catalog.
