Two ways in

Run your business on it.Or build on top of it.

Kylosys is a suite of business tools called modules. Owners use it as their whole back office. Developers and creators plug it into the apps, courses and client sites they ship.

For business owners

Your phone, inbox, customers, tickets, bookings and invoices in one friendly app, set up in an afternoon with no IT person.

Phone, inbox, customers, tickets, bookings and invoices in one friendly app.

  • Business phone system with local and toll-free numbers
  • CRM, helpdesk and shared inbox that share one customer record
  • Booking, invoicing and Stripe-powered payments
Explore all 18 modules

For developers & creators

Stop rebuilding accounts, billing and support for every launch. Connect Kylosys once and every new project ships with a back office.

For developers & creators

Your next launch alreadyhas a back office.

Every app, course or client site needs the same plumbing: accounts, billing, support and a way to get in touch. Kylosys is that plumbing, so you can spend your time on the part people actually came for.

01

Users, synced

Connect your sign-up flow to the API and every new account appears in your CRM with its source.

02

Support email, handled

Forward support@ to your own Kylosys inbox address. Every message becomes a conversation your team can answer.

03

Tickets & help centre

Turn messages into tickets with reply timers, and publish answers in a help centre on your domain.

04

A toll-free number today

Buy a toll-free number inside Kylosys and start taking calls and texts right away.

05

Billing, powered by Stripe

Subscriptions, invoices and payments run through Stripe, straight into your own account.

// 1. When someone signs up to your app
await kylosys.contacts.create({
  email:  user.email,
  name:   user.name,
  source: "signup",     // in your CRM instantly
});
// 2. React to what happens next
kylosys.on("invoice.paid", unlockCourse);

Independent or together

Stands alone.Works as one.

Switch off anything you don’t need and it simply leaves your sidebar. Nothing is deleted. Keep modules on, and they share one customer record so work flows from one to the next.

HELPDESK

Ticket #1052 opens

Priya writes to support@. The ticket already knows her plan and history.

PHONE

Priya calls the toll-free line

Her name, plan and open ticket pop up before you answer.

One record, every module. A caller in Phone is the same person as the contact in CRM, the requester on a ticket and the name on an invoice, so nobody types anything twice.

The modules

18 tools. One suite.

From a business phone system to Stripe-powered payments, every module is a complete tool on its own page, and every one is included in the suite.
