How Ozdingo Eliminated Inventory Errors with Sumtracker

About Ozdingo

Ozdingo is one of Australia’s fastest-growing multi-category online retailers, known for its wide assortment of household essentials, lifestyle products, beauty items, pet supplies, gifts, and general merchandise.

Unlike niche stores, Ozdingo operates as an “all-in-one everything store”, serving both individual shoppers and small businesses across the country.

Their inventory spans thousands of SKUs, many of which are sold as bundles, multi-packs, or curated sets. This bundle-first selling model creates higher order value for customers but adds complexity behind the scenes.

Every sale can involve multiple component items that need to be deducted accurately and instantly.

Ozdingo sells across two Shopify stores and Amazon FBA, all fulfilled from a single physical location. This means their operations depend heavily on reliable, real-time inventory visibility across all platforms.

The Operational Challenges They Faced

As Ozdingo continued to expand its product range and order volume, its existing manual workflow began to create avoidable friction.

The combination of bundle-heavy sales, frequent supplier restocks, and multi-channel fulfillment made it increasingly difficult to keep inventory accurate in real time.

1. Bundle Inventory Issues

Ozdingo’s catalogue relies heavily on bundles and multi-packs. Every bundle sale should deduct multiple component SKUs instantly, but manual updates caused delays. This led to inconsistent stock levels for individual components, making it harder to maintain accuracy.

2. Manual PO Mistakes

Purchase orders were created manually using spreadsheets. With multiple suppliers, varying pack sizes, and frequent cost changes, errors were common, including incorrect quantities, wrong purchase prices, or missing line items.

3. Multi-Channel Sync Gaps

Ozdingo sold across Shopify, Amazon FBA, and a second Shopify store. Stock had to stay perfectly aligned across all platforms, but manual syncing led to discrepancies. Even small delays resulted in mismatched inventory numbers between Shopify and Amazon.

4. High-Volume Stock Pressure

With thousands of SKUs and steady order volume, the team had little margin for delays or missed updates. Any inaccuracy in stock adjustments quickly caused downstream issues in fulfillment and customer orders.

5. Frequent Restock Complexity

Supplier restocks were frequent, and each restock needed to account for pack sizes, varying purchase prices, and updated quantities. Handling these manually increased the chances of incorrect inventory adjustments and misaligned costs.

6. Spreadsheet-Heavy Workflow

Most of the operational workflow ran through spreadsheets, POs, supplier details, cost changes, and stock updates. This made processes slow, repetitive, and prone to human error. It also made it difficult to maintain a single source of truth.

7. No Unified Inventory View

Inventory details were scattered between spreadsheets, Shopify, Amazon, and internal notes. Without a centralized system showing real-time stock across all channels, the team relied on manual checks and constant double-verification.

8. Risk of Overselling

Because stock updates were manual and delayed, especially for bundles, certain fast-moving items would occasionally show incorrect availability online. This created the risk of overselling, leading to backorders or customer service issues.

How Sumtracker Solved Their Stock & PO Problems

Sumtracker replaced Ozdingo’s manual, spreadsheet-heavy processes with a centralized system that automated every critical part of their inventory workflow.

Instead of updating stock across channels by hand or double-checking purchase orders, the team now relies on fast, real-time syncing and structured PO management that eliminates human error.

1. Real-Time Bundle Syncing

Every time a bundle is sold, Sumtracker instantly deducts the correct quantities from each component SKU. This ensures accurate stock levels at all times and removes the delays that previously caused mismatches or overselling.

2. Automated, Error-Free Purchase Orders

Sumtracker’s PO module handles supplier details, pack sizes, restock quantities, and purchase prices in one place. Ozdingo can now create POs without manual calculations, preventing quantity mistakes, incorrect costs, and missed line items.

3. Unified Shopify + Amazon FBA Sync

Stock updates flow automatically between their Shopify stores and Amazon FBA. Sumtracker keeps all three channels aligned so every platform reflects correct inventory, regardless of where sales occur.

4. Instant Inventory Adjustments

Instead of waiting for spreadsheets or staff updates, Sumtracker applies stock changes immediately. This speed is especially critical for fast-moving items and bundle components that require precise tracking.

5. Centralized Inventory View

Every SKU, bundle, purchase order, supplier, and restock sits inside a single system. The team now sees real-time stock levels, pending POs, and movement history without switching tools or double-checking values.

6. Reduced Manual Work and Operational Stress

By automating bundles, POs, and multi-channel syncing, Sumtracker removed the slow, repetitive tasks that consumed hours each week. The team now spends time on growth, not correcting manual errors.
