BookThatApp Alternatives for Shopify Rentals (2026)
The best alternative to BookThatApp for Shopify rental businesses is RentalFlow. It is purpose-built for physical product rentals with overbooking prevention, a delivery and returns dashboard, and damage tracking. Those are areas where BookThatApp falls short for rental stores, going by its listing and some merchant reviews on the Shopify App Store.
Why Merchants Look for BookThatApp Alternatives
BookThatApp is a long-running Shopify booking app with 418 reviews and a 4.7-star rating. It handles appointments, classes, tours, and rentals in a single app. But for merchants who specifically rent physical products, several common challenges surface repeatedly in App Store reviews:
Overbooking issues
Multiple merchants report that BookThatApp's availability checking is not always reliable. As one merchant wrote: "The app kept accepting bookings even when a limit was set, resulting in overbooking." For rental businesses where each physical item can only be in one place at a time, unreliable overbooking prevention means refunds, angry customers, and lost revenue — see how to prevent double bookings.
Mobile calendar bugs
The booking calendar has reported display issues on mobile devices. One merchant noted: "Calendar constantly resets itself to the same view" — a problem reported across 30+ devices. When most of your customers are booking from their phones, a broken mobile calendar directly impacts conversion rates.
Slow loading times
Some merchants report performance issues: "Very slow and takes minutes to complete." Page speed affects both user experience and search rankings. A booking widget that slows down your product pages can hurt conversion rates across your entire store.
Complex setup process
Because BookThatApp handles many booking types, the configuration can be overwhelming for merchants who only need rental functionality. As one review put it: "The system settings are not easy to configure and require an expert." Rental business owners should not need a developer to set up date-based booking.
Support concerns
While many BookThatApp reviews praise support, some merchants report difficulties getting issues resolved. Specific complaints include support being "unable to reproduce issues" and providing "condescending responses." When your rental business depends on an app working correctly, responsive and empathetic support matters.
None of this means BookThatApp is a bad app. Most of its 418 reviews are five stars. But for merchants who specifically rent physical products and need reliable overbooking prevention and operational tools, these limitations can be deal-breakers. If you also sell appointments, classes or tours, BookThatApp is still the better pick.
How RentalFlow Solves These Problems
Overbooking prevention. RentalFlow checks how many you own against every overlapping booking when the customer clicks Add to Cart. It does not just track dates — it validates that the physical item is available for the requested period before it goes in the cart. Learn more about how overbooking prevention works.
Fast, mobile-first booking widget. The RentalFlow date picker is designed for mobile devices from the ground up. No calendar resets, no slow loading — customers pick their delivery and pickup dates in seconds.
Simple setup. RentalFlow is built for one thing: physical product rentals. There are no appointment settings, class configurations, or tour options to navigate around. Install the app, add the widget to your product pages, set your default rental length and service area, and you are live in a few minutes.
Delivery and returns dashboard. BookThatApp handles the booking but leaves the operational logistics to you. RentalFlow includes a full delivery and returns dashboard — manage deliveries, confirm pickups, track return condition, and flag damage or lost items, all from your phone.
Calendar sync. Sync your rental schedule to Google, Apple, or Outlook Calendar. See all upcoming deliveries and pickups in the calendar app you already use. Read about calendar sync.

Other Alternatives to BookThatApp
RentalFlow is the best alternative for physical product rental businesses, but depending on your needs, other options may also be worth considering (see our full best Shopify rental apps comparison):
IzyRent
IzyRent ($24.99/month) is a solid choice for simple calendar-based booking. It has a 4.6-star rating across 129 reviews, and reviewers often praise its support. Its listing does not mention delivery management or damage tracking. Best for merchants who need basic booking without operational logistics. See our full RentalFlow vs IzyRent comparison.
Product Rentals Pro
Product Rentals Pro (free plan for 10 rentals, then $19.95-89.95/month) offers configurable gaps between bookings, which helps if you need turnaround time for cleaning or inspection. It has a 5.0-star rating across 52 reviews. The downsides are rental count caps on every plan, no calendar sync on its listing, and admin tools for fulfilments and returns rather than full delivery scheduling.

FlexCon
FlexCon (free for up to 10 rental orders a month, then $19.99-59.99/month) rents by the hour or the day and has a 5.0-star rating across 24 reviews. It launched in July 2025 and has order caps on every plan. Best for merchants who want to start for free at low volume.
