Serialized vs. Bulk Inventory in TWICE Commerce 2.0: Which Tracking Method is Right for You?

Choosing the Right Inventory Tracking Strategy: Serialized vs. Bulk

Effective inventory management is the backbone of any circular business, but not all assets require the same level of granularity. TWICE Commerce 2.0 offers the flexibility to manage inventory through both serialized records and bulk tracking, allowing you to tailor your operations based on the value and nature of your items.

Serialized Inventory for High-Value Assets

For high-value items where individual history matters—such as cars, heavy machinery, or premium electronics—serialized tracking is essential. By treating every single item as a unique row in your database, you ensure:

  • Specific Usage Tracking: Monitor specific metrics like mileage or hours used per unit.
  • Maintenance History: Keep a precise log of repairs and service for that specific asset.
  • Lifecycle ROI: Calculate the exact return on investment for each individual unit.

Bulk Tracking for High-Volume Accessories

Conversely, tracking every single unit individually can create unnecessary friction for lower-value or high-volume items, such as ski poles or cables. In TWICE Commerce 2.0, you can utilize bulk inventory records where a single row represents a quantity greater than one.

  • Aggregated Financials: Track income and expenses at a product level rather than an item level.
  • Operational Efficiency: Speed up check-outs and returns without scanning unique IDs for every accessory.

The Trade-Off

The decision comes down to data granularity versus operational speed. While bulk tracking simplifies management for generic items, it aggregates data. This means you lose the ability to connect specific wear-and-tear or income to a specific physical object in the real world. By leveraging the flexible infrastructure of TWICE, you can mix and match these approaches to build the optimal composable commerce stack for your rental or resale business.

Karri: Is the inventory always serialized? Is every single item one row in TWICE or are you also able to use bulk inventory records?

Tuomo: You can do kind of what is often referred as bulk tracking. Let's imagine you have your inventory open in TWICE 2.0. In that table every row can have a quantity and every row can have one or many unique stock codes that are used when reading barcodes and so on, that kind of references that inventory record.

The only difference is that if that row has a quantity above one, you kind of aggregate all of the information under that one inventory record.

So for something like a car, you probably want to know separate the actual mileage between two cars and the usage because they're so valuable assets. Now if you go to a category like, I don't know, skiing poles where it's not necessarily as important to know which one of these poles actually gathered the usage, but you rather want to track income and expenses on an aggregated level, then you might have a quantity for that inventory record level.

So yes, you can do bulk tracking. The only kind of cost, so to say, is that you lose some tracking capabilities when it comes to connecting the knowledge of which actual item in the real world incurred this cost or income or maintenance.
