Challenges Faced before Sumtracker

As sales expanded across Amazon FBA, Shopify, and multiple warehouse locations, the cracks in their inventory process started to show.

What once felt manageable became a constant source of errors, delays, and wasted effort. Without a unified system to keep everything in sync, small issues quickly turned into costly problems.

Here’s where the cracks began to show:

• No Unified Inventory View
  With sales happening on both Amazon FBA and Shopify, stock levels were fragmented between platforms, making it hard to get a single source of truth.

• 3PL and Internal Stock Managed Separately
  The 3PL updated Shopify directly, while internal and sample stock were tracked in spreadsheets, creating gaps and delays in visibility.

• Component Stock Was Invisible
  Labels, packaging, and raw materials weren’t consistently tracked in one system, leading to missed reorder points and production delays.

• Bundles Were Hard to Keep Accurate
  Shopify and Amazon handled bundles differently, making it difficult to sync and maintain correct stock levels across both channels.

• Restocking Was Always Late
  Without automated forecasting or reorder suggestions, replenishment only happened after items ran out, risking stockouts on bestsellers.

• Manual Work Drained Resources
  Spreadsheet-based updates for both products and components ate up hours each week that could have been spent on growth activities.

How Sumtracker Stepped In

After mapping out their pain points, the team implemented Sumtracker to bring every part of their inventory process under one roof. Here’s how it changed the game:

• One Source of Truth Across Channels
  Shopify and Amazon FBA were integrated with flexible rules, Shopify stayed the inventory master for 3PL locations, while Sumtracker took control of internal and sample stock.

• Centralized Bundle and Component Tracking
  Finished products were linked to their raw materials, packaging, and labels inside Sumtracker, ensuring every sale automatically updated component stock.

• Clean, Streamlined Product Data
  Non-sellable components were moved out of Shopify and tracked solely in Sumtracker, reducing clutter and preventing duplication.

• Smarter Stock Movement
  Internal transfers to the 3PL were handled directly in Sumtracker, keeping all location-level stock data accurate in real time.

• Sample Stock Finally Tracked
  All sample giveaways were logged as stock adjustments with clear reasons, making it easy to report monthly marketing costs.

• Faster Day-to-Day Operations
  Reordering warehouse lists in Sumtracker put the most-used locations at the top, saving time on daily inventory checks.
