The problem
My brother was starting a Shopify store renting out moving equipment: boxes, containers, that kind of thing. Shopify is built for selling products, not lending them, and he had no simple way to track rental inventory, bookings, and returns inside the admin he already used.
About
RentalFlow adds rental inventory, bookings, and availability to the Shopify admin. It was built for businesses that already use Shopify and do not want a separate system for rentals.
Method
How it works
Install the app
Add RentalFlow to your store from the Shopify App Store.
Set up your rentals
Mark products as rentable, set pricing periods, and configure availability rules.
Manage bookings
Track active rentals, upcoming returns, and inventory availability from one dashboard.
Key decisions
Build for one real customer, then list it
I built RentalFlow around one real workflow before listing it anywhere. I sat down with my brother, walked through how boxes and containers would go out, come back, and get counted, and turned that into requirements: what counts as a rental in Shopify terms, what a booking has to track, what the admin needs to show at a glance. Once the app fit his workflow, I listed it on the Shopify App Store to see whether other rental businesses had the same problem.
Service Notes
What went wrong
His store never opened. He ran into health problems right as he was getting ready to launch, and by the time he had recovered he had taken a job instead. So RentalFlow went to the App Store without the customer it was built for.
The Shopify App Store review took three to four weeks. After shipping seven apps through Apple's review, I had expected the process to feel familiar. Instead, I learned how much the review timeline and requirements can vary by platform.
One store started a paid plan, then cancelled with the feedback "not the correct app for my store." That was disappointing, but it also exposed a gap between the listing and the workflows the app actually supports. I still check usage, but it remains a low-priority bet unless demand gives me a reason to change that.
Results
- No paid marketing
- The listing is live on the Shopify App Store. One paid plan started and cancelled. Not a current priority.
