The Operating System for Circular Commerce
One platform can't do it all. Neither can one team. From your first rental to your ten-thousandth, you get three platforms — each built by specialists obsessing over subscriptions, assets, and fraud. So you can obsess over growth.
Three platforms. One workflow.
Shopify's circular revenue engine
Subscriptions. Rentals. Leases. Buyouts. The revenue cycle in circular commerce isn't a straight line — it loops. Firmhouse handles the full cycle with Shopify: from first checkout to recurring payment to buyout to re-rent.
Everything Shopify Native
No separate rental sites, no external carts. Customers choose rent or lease right at checkout.
Any Recurring Model
Monthly. Weekly. Flex. Minimum term. Rent-to-own. Configure your model, not someone else's template.
Revenue Recovery Built In
Failed payments don't mean lost revenue. Smart dunning retries, communicates, and recovers automatically.
Works With Your PSP
Mollie, Adyen, Stripe. Deposits, recurring charges, buyouts, refunds. The money moves, you don't chase it.


The circular native operating system
Scale your subscription business with a platform built for the complexities of access over ownership. BIYU orchestrates the entire physical lifecycle of your assets, ensuring operational excellence from order placement to the final refurbishment.
Real-Time Availability
Our smart engine prevents overbooking by calculating exact future availability based on rental periods, return shipping times, and refurbishment buffers.
Asset Tracking & DPP
We build a Digital Product Passport for every unit, tracking its location, usage history, refurb & repair history and condition throughout its lifecycle.
Flexible Fulfillment
Whether you outsource warehousing or manage in-house, we support every workflow: customer pick-up, 3PL integration, or your own delivery fleet.
Refurbishment Workflows
Streamline inspections, cleaning, and repairs with digital checklists. Every returning asset is graded, serviced, and instantly ready for the next customer.
Stop fraud before you ship
Every fake customer costs you a real product. Guzco.ai screens every transaction automatically, flagging risk before you pack the box — without slowing down legitimate customers.
Risk Scoring
Every order gets a fraud score before it ships. High risk? Flag it. Low risk? Ship it. Set your own thresholds.
Cross-border Compatible
Built specifically for rental and subscription fraud patterns, not generic e-commerce rules that miss the real threats.
Automated Decisions
Set your risk thresholds. Orders that pass go straight through. No manual review bottleneck for good customers.
Protect Without Friction
Legitimate customers don't feel a thing. Fraudsters get stopped. Your margins stay protected.
