In traditional linear retail, inventory is simple: one SKU represents thousands of identical items. However, in circular commerce—whether buying back goods, renting them out, or selling secondhand—this model breaks down. The core assumption of the circular economy is that every single item in your stock is unique in its nature.
Because uniqueness is unstructured, what matters to one business might not matter to another. A luxury handbag reseller needs to track condition grading and authenticity certificates, while a heavy equipment rental company needs to track engine hours and maintenance schedules.
Standard inventory management systems often fail here because they force merchants into rigid taxonomies. To scale a circular business, you need an inventory management solution that supports specific, individual-level tracking.
At TWICE Commerce, we have engineered our Recommerce OS to handle this complexity through Dynamic Attributes. This allows merchants to:

Tuomo: A core assumption of circular commerce, whether it's buying back goods or renting goods or selling secondhand, is that each one of your items that you have in your stock is unique in its nature.
There's so many ways on how to be unique that if you want to have an inventory management solution that supports that, you first have to enable this uniqueness on a tracking level. So every item needs to be able to be tracked on an individual level. But also this uniqueness is quite unstructured. What is unique to my business might not be the same as how someone else models it.
So you need very dynamic ways of attributing or describing items. It cannot really come from the OS itself forcing you to say that this is the taxonomy in which you have to describe things. You need to be able to be very flexible in saying what kind of stuff you track and store per item.
And this uniqueness is something that we've spent a lot of time in, allowing you to have completely dynamic attributes, for example, for every asset that you have. Basically meaning that you can store whatever data you want per asset, even doing things like calculated attributes where, for example, residual value for a used item is calculated based on other attributes like usage hours or purchase price.
