How do I manage inventory across both events?

Question

As an e-commerce business owner, I'm struggling to effectively manage my inventory during multiple sales events like Black Friday and Cyber Monday. I need strategies to track stock levels, prevent overselling, and ensure I can fulfill orders across both high-traffic periods without running out of popular items or getting stuck with excess inventory. My current system feels manual and error-prone, and I'm worried about potential lost sales or customer disappointment due to inventory mismanagement.

Managing Inventory Across Black Friday and Cyber Monday
The BF-CM stretch is the most inventory-intensive period of the year. The brands that manage it best treat it as one continuous planning horizon, not two separate events. Inventory decisions for Cyber Monday should be made before Black Friday starts, not after it ends.

Shopify as IMS
For most Shopify merchants, Shopify itself is the inventory source. Use Locations to separate BF-only stock from CM-reserved stock if needed. Real-time sync across online store and POS is built in.

Third-Party IMS (Cin7, Linnworks, etc.)
For multi-channel brands with warehouse fulfillment, a dedicated IMS syncs to Shopify and all other channels. Ensure the sync is real-time, not batch-updating every few hours.
