Imagine 250 homeowners vying for 21 prime lake buoys, with a reservation system held together by spreadsheets and good intentions. That was the reality for one homeowners’ association (HOA) until Brian Anderson of Tahoe Web Company stepped in to help with a custom built WooCommerce reservation system.
This case study covers how Brian helped a Northern California HOA move from chaos to control using Rental Products for WooCommerce and some clever custom logic to build a seasonal booking solution that:
- limits the total number of rentals available to members,
- simplifies admin work for administrators,
- and keeps everyone happy. Well, almost. (We’ll come back to the one or two grumbles.)
While Rental Products for WooCommerce handled the core availability and booking logic, this build required additional customization to enforce the HOA’s strict 21-day seasonal limit. Brian’s own detailed write-up goes deep into the technical side of his custom implementation.
What follows here in this post is our take on the business challenge, the product thinking, and how WooCommerce can power smarter booking systems when paired with purpose-built tools.
We also touch on how you can implement a similar (albeit slightly less perfectly-suited for the specific use-case) setup without custom code!
The challenge: enforce reservation limits without annoying members
The homeowners’ association needed a way to manage summer reservations fairly:
- Each member gets 21 peak-season days (June-August)
- Buoys must only be booked by approved, insured boat owners
- No duplicate accounts, link-sharing, or overbooking
- System had to be intuitive for non-technical users
Their old setup running Squarespace, manual form approvals, and a third-party calendar wasn’t cutting it.
There was no way to control who booked what, or for how long. It was really just a bunch of patchwork solutions that relied on a few familiar people to keep on top of just about everything. And it relied, actively, on the honor system to ensure people weren’t setting themselves up with more dates than they deserved.
“We had to cancel reservations manually, refund people, and try to enforce the 21-day rule with spreadsheets and good intentions. It just wasn’t sustainable.”
In a lot of ways, the possibility for abuse was a bigger problem than any real abuse.
People knew that other people might be taking more than their fair share, and the possibility was a mild frustration for everybody involved, even if they had no intentions of taking advantage of the loopholes themselves.
Why building a WooCommerce reservation system with Rental Products made sense
Brian tried several rental plugins before choosing Rental Products to build his WooCommerce reservation system. Most couldn’t handle one critical nuance: WooCommerce doesn’t track rental duration by default. A 1-day and 10-day rental both appear as a quantity of one, making it nearly impossible to enforce limits based on time.
Rental Products stood out because it was built to handle real-world rental logic.
It uses a calendar-based system to track availability and duration, supports blackout dates and seasonal rules, and integrates seamlessly with WooCommerce’s checkout, payment, and refund flows. It also offers flexible shortcodes that made it easier to combine with custom logic.
While it didn’t include built-in support for enforcing duration limits across multiple orders, Rental Products was the best foundation Brian was able to find to build on. Especially for a dev who wanted to keep the user experience simple and admin-friendly.
The solution: Rental Products plus custom enforcement logic
To enforce the 21-day max, Brian wrote a custom plugin that hooked into WooCommerce’s core order and cart logic.
By examining a member’s past orders and the contents of their current cart, it could tally how many on-peak days had already been booked, how many were about to be added, and whether the total exceeded the allowed 21 days.
Rather than introducing a new admin interface, Brian opted for a single shortcode placed in the reservation flow. That shortcode checked totals in real time, displayed a message showing the member’s current usage, and blocked checkout automatically if the limit was exceeded. The plugin even accounted for cancellations and refunds, ensuring that returned days went back into the member’s available quota.
Everything in Brian’s WooCommerce reservation system worked with existing WooCommerce and Rental Products data. No extra dashboards. No complicated manual workflows. Just a smart, seamless layer of logic built for the specific needs of his client, reserving buoys only to people who should have access.
Launch results: $20K in bookings, zero chaos
Once the homeowners association opened up reservations, usage spiked immediately:
- Over $20,000 in bookings in the first 48 hours
- Most users hit their 21-day cap within days
- Invalid users and bypass attempts were shut down cold
The launch was more than just a technical success. It changed the dynamics for the HOA team who had to manage the system. Instead of fielding dozens of support requests, manually verifying eligibility, or cross-referencing spreadsheets, admins could sit back and watch the system enforce rules on their behalf. For members, the process was faster, clearer, and more transparent. Everyone knew where they stood.
And looping back to the fact that not everybody was completely happy: yes, some people were frustrated they couldn’t “cheat the system” anymore. But that frustration was proof it worked. Thanks to Brian’s WooCommerce reservation system, and for the first time, the HOA had real policy enforcement and it didn’t come at the cost of a good user experience.
Takeaways for other WooCommerce builders
This wasn’t a massive custom SaaS. It was WordPress, WooCommerce, and a few carefully chosen plugins:
- Rental Products gave the client a visual, flexible scheduling interface
- WooCommerce handled payments, refunds, and user accounts
- Custom logic added rules that mattered to this specific community
If you run or serve clients with:
- Limited-access resources
- Duration-based pricing or restrictions
- Seasonal booking policies
…you can follow this same approach. Especially if you want something fast, familiar, and extensible.
This project is a great reminder that with the right tools, WooCommerce can power serious reservation logic.
We’re already thinking about how future versions of Rental Products could support more usage-based rules out of the box. If you’ve built something clever, let us know!

Bonus: Want the no-code version of a WooCommerce reservation system?
If you’re not up for writing custom plugins, there’s another way to build controlled reservation systems with WooCommerce:
- Use Constellation to create gated access. Only members with an active membership can book products or services.
- Combine with Account Funds to give members credits or “vouchers” they can use during specific seasons or limits.
- Use categories and purchase restrictions to ensure only certain products are accessible during the right time windows or membership tiers.
It won’t replicate Brian’s full logic out of the box, but for many sites looking to implement a similar system without customization, this combo gets you 90% of the way without custom code.
We’re always excited to see what WooCommerce and Rental Products can do in the wild, and this project is one we’ll be bragging about for a while.
