Rent it. Buy it. Trade it in. One operation. One system.
For companies offering customers multiple ways to access and return products — BIYU manages all of those flows simultaneously, with one source of truth across every channel and every asset.
All commercial models in one storefront
One asset record across every flow
Automated transitions, no manual reconciliation
Intelligence on when to shift models
The market is moving towards circular commerce — brands and operators offering customers the choice to rent, buy, subscribe, or trade in, sometimes all from the same checkout. The companies building for this shift are moving now.
Running multiple commercial models on separate systems is how operations break. Inventory splits across platforms. Asset records become inconsistent. Finance teams lose visibility. Operations teams work around the gaps. BIYU unifies all of it — one platform for every commercial model you run, with every asset tracked through every flow regardless of how it moves.
The flows your operation needs to handle.
Circular ecommerce is not one model. It is several running simultaneously — and BIYU handles all of them without manual reconciliation.
Rental + buyout
A customer rents a product, decides they want to keep it. The rental converts to a sale. The asset record updates. Billing adjusts. No manual intervention.
New stock + refurbished resale
New inventory sits alongside refurbished stock from returned or traded-in assets. Both available in the same storefront, priced differently, tracked separately.
Trade-in feeding rental fleet
Customers trade in products that are graded, refurbished and moved directly into the rental fleet. Pre-loved stock levels managed automatically.
Try before you buy
A customer receives a product on a trial basis. At the end of the trial they buy, return or subscribe. Each outcome routes the asset correctly without manual handling.
Sell off aging fleet
Rental assets that have reached the end of their useful rental life are relisted for resale. Asset ROI data tells you exactly when that point is reached.
Every asset. Every flow. One record.
In a circular operation, the same physical asset might be sold new, traded back in, refurbished, added to a rental fleet, and eventually relisted as pre-loved — all within two years. BIYU follows that asset through every one of those transitions.
One record. Full history. No gaps. Your operations team sees where every asset is. Your finance team sees what every asset has earned across its entire lifetime. From the same system.

Know when to keep renting. Know when to sell.
The most valuable thing a circular operation can know is not just where an asset is — it's what to do with it next. As rental revenue per cycle declines and an asset's residual resale value becomes more attractive, BIYU surfaces the recommendation: keep it in the fleet, or relist it and recover that value now.
This isn't an average or a rule of thumb. It's a per-unit calculation, based on the actual performance history of that specific asset.
Rent vs. Sell
Is it more valuable to keep renting this item, or sell it now at its current residual value? BIYU models projected rental income against depreciation and residual price to give you a clear break-even view.

Consumer behaviour is already circular. Operations need to catch up.
Klarna and eBay's integration drove one million resale listings in three months. Bol.com now sells refurbished products alongside new ones. Brands that once sold only new products are launching rental and trade-in programmes. The companies winning in this environment are the ones whose operations can handle all of it without adding headcount or systems.
BIYU is the infrastructure for that.
Real operations. Real results.

Frequently asked questions
Circular ecommerce is a retail model where products are sold, rented, traded in, or resold through a single connected operation — rather than separate linear channels. Instead of a product moving from warehouse to customer and ending there, it moves through multiple lifecycle stages: initial sale or rental, return, refurbishment, and resale or re-rental.
A circular ecommerce platform is software that manages multiple access models — new sales, rental, subscription, trade-in, resale — through one operational backbone. It keeps inventory, availability, fulfillment, and asset history in a single system rather than fragmenting across separate tools for each channel.
Yes. BIYU integrates with existing ecommerce storefronts to add rental, subscription, and trade-in options alongside standard purchase — without rebuilding the storefront. Inventory, availability, and order management are handled by BIYU, connected to the existing customer-facing experience.
It means that a single system holds the complete record for every physical asset — its current location, condition, availability status, full order history, refurbishment history, and lifetime economics. When inventory, orders, fulfillment, and analytics are managed in separate tools, that record gets fragmented. A unified circular ecommerce platform maintains it in one place.
BIYU is designed for businesses running more than one access model at the same time — for example, selling new products, renting the same SKU, and running a trade-in programme in parallel. Inventory allocation rules, pricing logic, and fulfillment workflows are configured per model and per product category, while all assets are managed through the same operational system.
