What clubs say

Real words from real admins

Member Splash has completely transformed our ability to track membership, manage events, and run our Snack Bar with the POS. Most importantly, it has made our processes easier for members, staff, and volunteers. We cannot stress enough the value it has brought to our club.

Drew Powers · Bower Hill Swim Club

Before Member Splash, our membership system was literally a card box. I spent weeks tracking down payments by hand. Now everything is streamlined — payments, check-ins, and more in one place. Member Splash has saved me countless hours and completely changed how smoothly our club operates.

Lauren DiStefano · Oakwood Valley Swim Club

Photo IDs stopped membership misuse, streamlined payments and reservations, and guest passes can now be purchased in bulk with no lost revenue. It simplified operations for both our staff and our volunteer board.

Ryan Wenstrup-Moore · Mt. Lookout Swim Club

We switched in 2017 and have never looked back. It's by far the easiest registration system we've ever used. The support staff is responsive, professional, and always kind. The level of service makes the whole experience truly priceless.

Frequently Asked Questions

Everything clubs, HOAs, and pool management companies ask before switching to Member Splash. Tap any question to see the answer.

Member Splash is an all-in-one club management platform built specifically for swim clubs, tennis clubs, aquatic facilities, homeowner associations (HOAs), and pool management companies. Instead of relying on multiple software products for memberships, payments, reservations, communications, check-in, reporting, and daily operations, Member Splash brings everything together into one connected platform.

Built on more than 16 years of real-world industry experience, Member Splash helps organizations simplify operations, improve the member experience, increase revenue opportunities, and reduce administrative work. From the first online registration through daily facility operations and season-end reporting, Member Splash provides the technology clubs need to operate more efficiently while delivering a modern digital experience for their members.

Member Splash was purpose-built for organizations that manage memberships, facilities, seasonal operations, and community engagement. Our platform is trusted by:

  • Swim Clubs
  • Tennis Clubs
  • Aquatic Centers
  • HOA Communities
  • Property Management Companies
  • Pool Management Companies

Whether your organization is managed by volunteers, a professional staff, or a management company overseeing multiple facilities, Member Splash provides the tools needed to streamline operations, improve communication, and create a better experience for both administrators and members.

Member Splash includes everything organizations need to manage memberships and daily operations from one connected platform. Core features include:

Rather than forcing clubs to manage several disconnected systems, Member Splash combines these capabilities into one platform that shares data across every part of your organization.

Running a successful club involves hundreds of repetitive administrative tasks every season. Member Splash automates many of those processes so your staff and volunteers can spend less time managing paperwork and more time serving members.

Instead of manually tracking memberships, collecting payments, processing registrations, checking members into facilities, managing reservations, and answering routine questions, Member Splash centralizes these workflows into one easy-to-use system.

Administrators gain real-time visibility into memberships, finances, attendance, reservations, and operational activity while members enjoy faster registrations, convenient online payments, digital communication, and self-service access to their accounts. The result is a smoother experience for everyone involved.

Yes. Member Splash includes tools specifically designed for pool management companies that oversee multiple facilities, communities, and client organizations.

Management companies can centralize memberships, communications, reservations, staffing, reporting, and facility operations while maintaining individual branding and administration for each client location. Managers gain visibility across every facility without sacrificing the flexibility each community requires.

Whether you're managing five pools or hundreds, Member Splash helps standardize operations while reducing administrative workload across your entire organization.

Many organizations initially choose Member Splash to simplify operations, but quickly discover it also helps create new revenue opportunities.

Features like online payments, guest pass sales, facility reservations, swim lesson registration, event registration, Splash Cards, and automated billing make it easier for members to purchase services while reducing missed payments and administrative bottlenecks.

By removing friction from the purchasing process and making club services more accessible, organizations often see increased participation and improved revenue collection — all while reducing the workload required to manage those programs.

Absolutely. Member Splash was designed with both administrators and members in mind. Members can register online, manage their accounts, purchase guest passes, reserve amenities, sign up for programs, receive communications, and access important club information from any modern device.

The interface is intuitive and mobile-friendly, allowing members to complete common tasks in just a few clicks while reducing support requests for club administrators.

A better member experience leads to happier families, fewer administrative questions, and more efficient club operations.

Unlike generic membership platforms, Member Splash was built specifically for the unique needs of swim clubs, aquatic facilities, HOAs, and pool management companies.

General membership software often requires extensive customization or multiple third-party products to handle reservations, guest passes, seasonal memberships, photo check-in, Splash Cards, and aquatic-specific workflows. Member Splash was designed around these operational challenges from day one.

The result is a platform that feels like it was built specifically for your organization — because it was. Instead of adapting your operations to fit generic software, Member Splash adapts to the way clubs actually operate.

Member Splash offers simple, transparent annual pricing designed specifically for swim clubs, HOAs, and pool management companies.

Unlike many software providers that charge by the number of members, add expensive implementation fees, or require purchasing multiple modules, Member Splash keeps pricing straightforward and predictable. Our plans are designed to fit organizations of different sizes while providing exceptional long-term value.

We encourage organizations to compare features side-by-side to determine which plan best fits their operational needs. View our Pricing Comparison page to explore all available plans, included features, and pricing options.

We believe software should support your organization's growth — not penalize it.

Many membership platforms charge based on the number of members in your system or place limits on how many members you can manage before requiring a more expensive plan. As your club grows, so do your software costs. Member Splash takes a different approach.

Our flat annual pricing gives your organization predictable costs throughout the year, making budgeting easier for volunteer boards, management companies, and community organizations. Instead of worrying about unexpected fees every time membership increases, you can focus on growing your club, serving more families, and improving the member experience.

You'll always know what your annual investment will be, allowing you to budget confidently while avoiding the surprise costs often associated with per-member pricing models.

Absolutely. Member Splash was built with growth in mind.

Whether your organization expands its membership, adds new amenities, launches additional programs, or increases staffing, our platform is designed to scale with you. Unlike many membership systems that place limits on the number of members you can manage or increase your subscription simply because your membership grows, Member Splash is configured to help your organization succeed — not charge you for succeeding.

We believe healthy clubs should be encouraged to grow. That's why we don't impose artificial member caps or use per-member pricing that penalizes organizations for attracting more families.

If your operational needs evolve and additional capabilities become valuable, upgrading to another Member Splash plan is simple and seamless. Your members, data, settings, history, and configurations remain intact, allowing you to unlock additional features without rebuilding your system or migrating to another platform.

Our goal is to become a long-term technology partner that grows with your organization — not one that profits from limiting it.

Yes. Member Splash includes Poseidon AI — AI assistance built directly into the platform, not a separate product.

Poseidon AI currently gives boards and members a hand with specific, everyday tasks: scheduling facilities, generating club media, and guiding new users through onboarding. It's available today, with more capabilities on the way.
