CRM & Portals
Membership accounts, renewals, payments, bookings and resources, a portal that runs itself so your committee or team does not have to.
This is the member portal development NZ clubs, associations and gyms turn to when renewals, payments and bookings eat the committee's evenings. Superstack builds a portal where members join, pay, renew and book themselves, and the treasurer sees it all reconciled in your accounting software without a spreadsheet.
the committee is the software
member portal development that renews itself
Off-the-shelf membership portal software makes your club fit its tiers and fees. We build around your rules: who joins, what each tier gets, when renewals fall due and what the committee sees.
01 of 8
Each member has an account with tier, status and history. Tiers carry their own fee, benefits and rules: a junior member needs a guardian, a corporate member covers staff. A rowing club sets up family memberships once, and the portal knows who belongs to whom.
02 of 8
Renewals run on the dates you set. The portal reminds the member, takes payment by card or direct debit and updates their status. A gym on monthly memberships never chases a failed payment: the portal retries, then sends a link to update the card.
03 of 8
Members book courts, classes or event tickets from the portal, with limits by tier and a waitlist when a session fills. Any payment is taken at booking. A netball association opens winter registrations on Monday night and sees team numbers by Tuesday.
04 of 8
Documents, recordings, templates and guides sit in a searchable library with access by tier. An industry association puts its bulletins and template contracts behind the member login, so a new member finds years of material on day one, not buried in old newsletters.
05 of 8
Members find each other through a directory they control: each person chooses what to show, from name only to full contact details. A professional body's members search by region and area of practice. Non-members see nothing, and a member can opt out.
06 of 8
Send email or SMS to the right members: everyone, one tier, or the people who booked a cancelled session. Members set their own preferences, and every message is logged. A community organisation announcing a venue change texts only the members booked for that night.
07 of 8
The committee gets the monthly meeting numbers without anyone compiling them: members by tier, renewals due and overdue, income by month, event attendance. The treasurer exports a reconciled list that matches your accounting software, and any committee member with the right role can look.
08 of 8
Members use their phones, so every screen suits a thumb: renew in two taps, show a membership card at the door, book a class from the car park. A gym member portal that works on a cracked phone is the one they keep using.
A new member joins on the website, picks a tier and pays. The portal creates the account, the receipt and your accounting software entry, and opens the resource library. They book the season launch. Months later the renewal reminder goes out, and on the due date the portal charges the card on file. The committee reads the report and sets the fees. Nobody chases.
Stripe takes card payments and GoCardless takes direct debits, each payment tied to a member and a period. Your accounting software receives invoices and payments. Mailchimp gets your member segments for newsletters. Google Workspace and Microsoft 365 handle committee sign-in, and Twilio sends the SMS reminders.

HubSpotAI is optional. Renewals, payments and bookings run on rules without it, and we add AI only where it saves a volunteer time. See how we use AI and business process automation.
A member asks about grading rules and gets the answer from your documents.
A list like lapsed members who used to attend events, from a plain description.
Members whose attendance and logins have dropped before renewal, so someone rings them.
The committee run the portal from a browser: approving applications, setting tiers and fees, publishing events and pulling the monthly report. Roles keep the treasurer's view separate from the coach's.
Members who want an app get one: a digital membership card, push reminders for bookings and renewals, and the same login as the portal, which suits gyms and clubs with daily check-ins.
The member login website is where most members live: join, renew, pay, book and read resources. All three share one database, so a card updated in the app pays the next renewal.
Season registrations, family memberships and court bookings, with numbers ready for the AGM.
Industry associationsAn association member portal with tiered corporate memberships, a technical library and event registrations.
Gyms and studiosMonthly direct debits, class bookings, a digital card and failed-payment recovery.
Community organisationsRenewals and event RSVPs that run without a volunteer remembering to chase.
Professional bodiesCPD records, member grades, a searchable directory and annual renewals.
Quickest start
We customise the existing Superstack membership module with your tiers, fees and renewal dates, the fastest route to renewals on autopilot.
Most common
We combine membership with event booking, resource booking, waivers and a customer app into one platform.
Fully bespoke
A bespoke build for national bodies with branches, complex grading or affiliation rules, or several organisations under one roof.
Off-the-shelf platforms work until your rules stop matching theirs: a family tier they cannot model, a grading system, a regional fee. Then you pay per member to work around it. We build the rules you have, charge for the build rather than per member, and connect it to your accounting software and Stripe you already use.
Yes. Stripe handles card payments and GoCardless handles direct debits, and members choose at sign-up. Recurring memberships renew on the stored method, with retries and an email when a payment fails. One-off purchases like event tickets go through the same checkout. Every payment carries the member, period and fee, so reconciliation is done.
Yes, because the core is the same: people, tiers, money and dates. A club membership portal needs season registrations and family memberships. A gym needs monthly debits, class bookings and check-in. An association needs corporate tiers, a resource library and a directory. We build the modules you use and leave out the rest.
Yes. The portal works on any phone, and we can add an app that shares its database: a digital membership card, push notifications for bookings and renewals, and faster check-in at the door. Start with the portal and add the app once members ask for it. Our customer app development page has more.
Member and payment details are the most sensitive data a club holds. Card and bank details never touch our database: Stripe and GoCardless hold them. Everything else sits in an encrypted database with access by role and a log of who viewed what. Members can see and correct their own record.
Yes. Bring the spreadsheet or the old platform's export. We match the columns to your new tiers, remove duplicates and bad emails, and load a trial copy for the committee to check. Joining dates and history come too. Stored cards come across where the old provider allows it, otherwise members enter a card once at renewal.
