Everything You Need

Multichannel inventory software built for how you actually sell

Not enterprise bloatware. Not a spreadsheet. The right tools for growing multichannel sellers.

Real-Time Inventory Sync

Every sale on any channel triggers an instant update across all others. No delays, no batch jobs, no stale numbers.

Single Dashboard

View and manage stock levels across all your channels from one place. No more switching between browser tabs.

Low Stock Alerts

Get notified when any product drops below your threshold on any channel. Restock before you run out.

Variation Support

Sync individual variants (size, color, style) independently. A sale of one variant only decrements that specific option.

Bulk Updates

Update quantities across multiple products and channels at once. Restocks, corrections, and price adjustments in seconds.

Oversell Prevention

Real-time locking prevents the same item from being sold twice across channels, even when sales happen simultaneously.

Before & After

From chaos to one clean source of truth

Here’s the difference between managing multichannel inventory manually and using software built for it.

✗ Without Commerce Kitty

  • Five browser tabs open, five sets of stock counts to maintain
  • Every sale requires manual updates on every other platform
  • Inevitable oversells during busy periods or when you’re away
  • Canceled orders accumulate and hurt ratings across all channels
  • No single view of what you actually have available right now
  • Scaling to more channels means multiplying the manual work

✓ With Commerce Kitty

  • One dashboard. All channels. Always accurate.
  • Sales on any channel automatically update every other channel
  • Zero oversells. real-time sync with race condition protection
  • Clean account history, stronger ratings, more repeat buyers
  • One number to check: your real available stock
  • Add more channels without adding more work

We sell on Shopify, Amazon, eBay, and Etsy. Before Commerce Kitty, inventory management was a part-time job. Now it’s completely automatic. We added two new channels last month and it didn’t add a minute of work.

FAQ

Multichannel inventory software questions

How many channels can I connect?
You can connect as many channels as you need. Commerce Kitty currently supports Shopify, Amazon, Etsy, eBay, WooCommerce, and BigCommerce. New integrations are added based on seller demand. if you need one that isn’t listed, let us know.
How is Commerce Kitty different from ChannelAdvisor or Linnworks?
Commerce Kitty is built for independent sellers who need powerful sync without enterprise complexity or enterprise pricing. No implementation consultant, no minimum contract, no six-figure annual fee. Set up yourself in minutes, free plan included.
What happens if two customers buy the same last unit simultaneously?
Commerce Kitty uses optimistic locking to handle simultaneous sales. The first confirmed transaction updates all channels. The second customer sees the item as unavailable. You never accidentally commit to two orders you can only fulfill once.
Can I set different stock levels per channel?
Yes. You can configure per-channel stock buffers. For example, you might want to hold back 2 units on eBay while showing the full count on Shopify. Commerce Kitty handles the math automatically.
Do I need to keep my spreadsheet once I connect?
No. Commerce Kitty replaces your spreadsheet as the central source of truth. Set stock levels once, and they propagate across every channel. You can export reports at any time if you need a snapshot.

Your inventory shouldn’t require a spreadsheet and five browser tabs

It’s 2025. Your multichannel inventory should sync itself. Start free and see why sellers replace their spreadsheets with Commerce Kitty.
