Selling on Shopify and Amazon? You’re Probably Overselling.

Avoid overselling on Amazon and Shopify with unified ERP system

Why You’re Losing Sales Without Realizing It

If your eCommerce brand sells on both Shopify and Amazon, there’s a high chance you’re already experiencing Shopify Amazon inventory sync issues.

Although orders may be flowing in steadily, the backend can often be chaotic. Overselling is one of the most common and damaging results of poor system sync—and most of the time, it’s invisible until customers start complaining.

For example:

  • Stock shows as available

  • Customers place orders, but the item turns out to be out of stock.

  • But the item is out of stock

As a result, This forces businesses to cancel orders, face bad reviews, and manage unhappy customers

What Causes Overselling in Multichannel Setups?

Many growing brands operate with a similar setup:

  • Shopify for direct-to-consumer sales

  • Amazon for marketplace orders

  • One or more plug-ins to sync inventory

  • Spreadsheets for edge cases

  • A warehouse management system that’s only partially connected

However, this setup often creates more problems than it solves.

The main reason is that these systems don’t sync in real time. Instead, Most systems update inventory in delayed batches—or sometimes skip it altogether.. Because of this, you end up selling inventory that’s already gone.

As the business scales, these sync delays grow from an occasional inconvenience into a consistent bottleneck. Meanwhile, your customers expect flawless order fulfillment.

Consequently, the same stock gets sold on two platforms, pickers are misled, and warehouse teams operate blindly. Therefore, overselling continues unless the system is rebuilt to support real-time updates.

Why Sync Tools and Spreadsheets Are Not Enough

At first, using sync apps or spreadsheets might seem like an affordable way to manage multichannel inventory. However, they only delay the inevitable.

Here’s why:

  • Most tools sync every 10–15 minutes (or longer)

  • Teams often process returns manually.

  • Sales data is siloed from finance and accounting

  • No real-time overview of inventory movement

  • Human errors increase with every disconnected workflow

As a result, many brands are forced to manually reconcile data between platforms. This manual process wastes hours and often causes new errors. also introduces new errors. Over time, the cost of maintaining this setup outweighs the cost of upgrading.

Moreover, relying on spreadsheets limits collaboration and creates confusion when more team members get involved. Instead of simplifying, it complicates.
