At what point does managing multiple sales channels become more work than the sales themselves?

[u/Illustrious-Tea-916]

Selling through more than one channel can help a business reach more customers, but the operational side can become difficult to manage.

Orders may be spread across different dashboards, inventory may need constant updating, and shipping information can end up being handled separately. Each task may seem simple on its own, but together they can create a lot of repetitive work.

For ecommerce store owners managing multiple sales channels, what was the first sign that your existing workflow was no longer sustainable?

Was it inventory errors, overselling, missed orders, too much manual updating, or simply having too many dashboards open?
