Multichannel Inventory · Built by a CFO

Stop overselling.

One inventory. Every channel. And it tells you when something breaks.

Selling on Shopify, Etsy, and WooCommerce at the same time? ROSTA keeps one stock number across all of them — and alerts you the moment a sync stops working, instead of letting you find out from an angry customer.

The Problem

Your sync says "connected." It isn't working.

A sync that fails loudly is annoying. A sync that fails silently is expensive. Sound familiar?

😬
You sold what you don't have
The same item sells on two channels within minutes. Now you're emailing a customer to cancel — and eating the review.
💸
Ads running on out-of-stock items
Your catalog says it's available. You find out days later, after the ad spend is gone.
🔕
Nobody told you it stopped
A token expired. A webhook backlogged. Everything still looks connected. Nothing is updating.
📉
Your numbers are quietly wrong
Wrong stock means wrong COGS. Wrong COGS means wrong margins — and eventually a wrong tax filing.
📋
You're fixing it in spreadsheets
Manual entry "just to be safe" — the workaround that becomes a second job.
🕵️
You find out from a complaint
Your customer is your monitoring system. That's not a system.

What ROSTA Does

One stock number. Everywhere.

Built by someone who spent 12 years signing off financial statements — then wrote the code himself.

🔄
Sell once, everywhere updates
An order on Shopify drops the count on Etsy and WooCommerce too. Shopify updates in real time; Etsy and Woo sync automatically.
🚨
It tells you when it breaks
If a channel stops syncing, you get an email — not a customer complaint. This is the part most tools skip.
📚
Books that actually tie out
Every sale posts to a real general ledger. Your inventory, COGS, and margins agree — because they come from the same source.
🧾
US sales tax, built in
All 50 state rates included. Add county rates when you need them. No plugin, no spreadsheet.
🔗
Works with QuickBooks — or without
Keep QuickBooks and add an inventory layer on top, or run ROSTA standalone with full accounting built in.
📊
Reports you'd hand an auditor
P&L, balance sheet, cash flow, trial balance, AR/AP aging, audit trail. GAAP and IFRS. Not a dashboard — real statements.

Pricing

Pay for the channels you actually sell on.

Three different products, not three sizes of the same one. Pick the one that matches how you keep your books, then add $100/month per sales channel (Shopify, Etsy, WooCommerce — Amazon and eBay coming soon).

Why ROSTA

Most sync tools are built by engineers.
This one was built by a CFO.

Engineers see inventory as data moving between two systems. I see it as something that lands in your books — and eventually, in front of an auditor.

🏛️
12 years as a CFO
Consolidated financial statements audited by EY, PwC, and Deloitte. I know what "wrong inventory" costs when it reaches the books.
⌨️
30 years across both worlds
Building software since 1999, and running finance the whole time. Not a team of engineers guessing at accounting — one person who has done both.
🤝
You talk to the person who built it
No ticket queue, no offshore support script. Email the founder — that's the whole support process.

Sell on more than one channel?

Ask your current tool one question: "How would I know if you stopped working?"
If there's no clear answer — let's talk.
