Sniza Appointment Scheduler is a self-hosted booking system for sites that sell instructor time in prepaid blocks. Students draw down minutes from packages assigned by an admin or purchased through WooCommerce, and book appointments against per-instructor availability.
Features:
<ul>
<li>Per-instructor weekly availability (timeblocks) and ad-hoc time off</li>
<li>Configurable package definitions in 30 minute increments up to 4 hours</li>
<li>Admin-assigned prepaid packages with optional expiration date and notes</li>
<li>Optional WooCommerce integration: mark packages as purchasable and auto-grant minutes when an order completes</li>
<li>Frontend month calendar with day-level availability indicators</li>
<li>Weekly time-slot view with status colours (available, booked, time off, blocked by another user, too soon, current)</li>
<li>Mobile single-day scheduler with mini calendar</li>
<li>Per-user appointment booking and cancellation, with a configurable cancellation cutoff</li>
<li>“My Lessons” view with AJAX-powered Future / Past filter and in-place cancellation</li>
<li>Admin Appointments screen with instructor and date-range filters (defaults to the next 3 days, hides cancelled lessons)</li>
<li>Configurable maximum appointment length (admin setting)</li>
<li>Sample-data tool for seeding and wiping a fixed demo dataset</li>
<li>Timezone-aware: each instructor has their own timezone, and end users see times in the site timezone</li>
</ul>
Available shortcodes:
<ul>
<li><code>[sniza_scheduler]</code> — booking UI (month calendar + week grid)</li>
<li><code>[sniza_packages]</code> — store front for purchasable packages (requires WooCommerce)</li>

This plugin adds a “Quick Reserve” widget to your wordpress weblog sidebar. With this widget you can display a list of services that you provide on the sidebar, so that your customers can make reservations online. In development of this plugin, we assume that your service is priced by time length.
Instructors, counsellors, lawyers, language teachers, etc, as long as you price your service by time length, this plugin gives you a good start point.
This plugin does NOT put HEAVY burden on your site, rather it uses a dedicated backend site. This means that you don’t have to be worried about many website settings and scripting work, such as emailing, user account menagement, gathering user information, calculating vacant time, avoid room conflicts, etc. It also avoids building a large number of database objects on your site, so that you don’t have to be worried about renting for strong enough servers to afford the heavily accessed database. In short, this plugin simply eliminates the expertise as a requirement of building a reservation site.
The backend is provided by Uniwits.com’s online reservation service (UORS) at http://reserv.uniwits.com . When using this plugin, you are publishing services that you create on UORS. Please to go UORS, register an account, and upgrade to business, for free, then follow the wizard to publish a service.
This plugin is developed under WordPress 3.0.1, but it only uses very basic functions.
