Lead forms

One attribute. That's the whole integration.

Add data-sleekcms to any form - your HTML, your design - and every submission is captured. No backend, no action URL, no JavaScript.

Customer leads dashboard

Every submission lands in your dashboard, grouped by form. View, filter, and manage leads without leaving the platform.

Straight to your inbox

Email notifications to any mailbox, so your team hears about every lead the moment it arrives.

Webhooks to your CRM

Fire each submission at HubSpot, Salesforce, Mailchimp, or any HTTP endpoint - leads flow into the tools you already use.

Online booking

Add one field. Get a booking system.

Give a form a date-time input and SleekCMS turns it into a full scheduling flow: the input becomes an availability slot picker, and submissions become appointments - with your open hours, slot length, and capacity in control.

Your customer gets

A confirmation email, a calendar invite, and a manage link to reschedule or cancel - no account, no login, no phone tag.

You get

Appointments in your dashboard next to your leads, availability rules you control, and optional owner confirmation before anything is locked in.

It fits your design

The picker inherits your site’s accent color and lives inside your own form markup - it looks like you built it.

Built for appointment businesses

If customers book time with you, this is for you.

From first enquiry to confirmed appointment - without a separate scheduling subscription bolted onto your website.
