What you can try
- Join as a member: create an account, confirm your email, pay with the test card
- Gift a membership as a voucher
Set up a plan, honour its perks and watch it grow.
Set the price, billing period and perks, with limits that reset each period.
Everything you need to run a paid membership, from the first sign-up to the hundredth renewal.
Create plans with your own price, billing period, benefits and free trials. Members join online through your customer portal and can see their plan and perks at any time.
Payments are taken every period through your own payment account, with refunds and credit notes kept in line. Failed payments get a grace period that you set before access stops.
Set benefits such as "two free coffees a week". Staff open the member, press Redeem, and the allowance resets each period, so perks are fair and easy to honour.
Rank your plans and set the visits or spend that earn an upgrade. Members who qualify are flagged for an offer.
Sell plans to companies for their staff under one account, and let members use their membership across your sites. Visits at each site are recorded.
Active members, monthly recurring revenue and churn for every site, in one view. Spot a plan that’s losing members before it shows up in your takings.
Everything below comes with every plan, at one price per site, with no add-ons or per-user fees. Open each area underneath for the rest.

Work three ways: do it yourself, ask your AI teammate, or let them draft it and take over. A draft lands as a normal item you can edit, not a block of text to copy and paste.

Monthly, quarterly or yearly plans, free trials, perks with limits and plans that work across sites.

Payments are taken every period, failed payments get a grace period, and a new plan sets up its own billing.
Do it yourself: build plans in the Plans screen.
Ask Dev: Dev drafts the pricing and perks of a new plan.
Or take over the draft: it lands as a normal plan in the Plans screen once you approve it.

FREE · NO ACCOUNT · NO CARD
Give it a simple brief and the AI team builds a campaign, emailed to you with a read-only link. The picture shows what came back for a demo hotel’s brief.
A separate membership system and the manual work around it.
Glofox, ClubRight and Mindbody are another subscription with another customer list and another log-in for your team. Here memberships come with your plan and sit on the same customer record as everything else.
No more honouring benefits from memory or a note behind the bar. Every redemption is recorded against the member, and limits are enforced at every site.
Renewals, failed payments, refunds and cancellations are handled for you, with reminder emails and a clear status for every member, so nobody has to chase cards by phone.
YOUR AI TEAM, ON MEMBERSHIPS
Switch it on and it works around the clock. Nothing goes out without your approval.
Watches each plan for members who are set to cancel and members who have stopped coming in, and raises them before their renewal date so you can act in time.
Drafts a personal win-back message for members who have lapsed, in your voice and with an offer you choose, ready for you to approve.
Suggests new plans, offers and pauses for you to review, based on how members actually use their benefits. Nothing is created until you approve it.
Set up by real people, supported by AI. An mDOS Expert Partner sets up your plans, perks, trials and billing with you, and the AI team watches renewals and lapsed members once you switch it on.
Keep your current membership system while its contract runs out. We bring your members and their history across, and agree a switching plan that moves billing over without a gap in anyone’s membership.
Signing members up is half of it. Keeping them is the rest. mDOS adds AI agents that watch renewals and a team that helps you keep members.

Memberships and subscriptions with perks, automatic billing and renewals, with every member on one customer record.

AI agents spot members set to cancel or who’ve stopped coming in, draft a personal win-back message and suggest new plans, all for you to approve.

An mDOS Expert Partner sets up your plans, perks and billing with you, and partner marketers plan the emails that keep members engaged.
Working websites built on mDOS for invented businesses. Open one and try it the way your customers would.
