Aboutthistool.
SlotWise by Mytsys Software Solutions is a full-featured appointment booking plugin that auto-configures itself for your industry. Choose from 12 business categories (music studio, medical clinic, hair salon, beauty, car wash, fitness, dental, tutoring, massage, pet grooming, photography, cleaning) and the plugin pre-loads appropriate services, staff, time slots, and form fields — ready in minutes.
Customers book through a modern, step-by-step booking flow — choose a service, pick a staff member (or “any available”), tap a date and time, answer your questions and pay — that works beautifully on phones and fits into any theme. A complete admin dashboard manages bookings, staff, services, packages, discount codes and payments.
Key Features
Industry Setup Wizard — One-time wizard auto-configures services, staff, forms, and packages for 12 business types
Dynamic terminology — Admin labels, page titles, and menus update to match your industry (e.g. “Consultations” for medical, “Treatments” for beauty)
Step-by-step booking flow — Service → staff → date & time → details → review & pay, with a live summary bar, phone-friendly layout and an “Add to calendar” button
Per-staff availability — Customers choose a staff member or “any available”; each person can be booked at the same time and double-booking is prevented at database level
Two booking modes — Standard booking flow and Package booking flow
Multi-session packages — Create packages with name, description, price, session count, and featured badge
Service listings grid — Display all your services in a stylish card layout
Four payment methods — Card (Stripe Elements), PayPal Standard, Stripe, and Cash App
Discount & promo codes — Percentage or fixed amount, date ranges, usage limits, service restrictions, live front-end validation
Visual drag-drop form builder — Reorder, show/hide, and relabel booking form fields from admin
Admin dashboard — View, search, and manage all bookings; update status; filter by date/status; one-click cancellation with customer email
Email notifications — Automatic confirmation to customer + admin new-booking alert with HTML template
Data safety on update — Plugin upgrades never delete your data; dbDelta() + schema migration only adds columns, never drops them
Fully translatable — Uses standard WordPress i18n with .pot file (text domain: slotwise )
Theme-safe — All CSS is scoped to plugin wrappers; no global resets or overrides

Privacy
Customer data (name, email, phone, booking details) is stored in custom database tables on your WordPress installation. No data is sent to third parties except as required to process payments — see the External Services section below for full details.
No data is collected or sent to Mytsys Software Solutions.
External Services
This plugin connects to the following third-party services to process payments. These services are only contacted when a customer submits a booking with the corresponding payment method selected. You must enable each payment method explicitly in Settings — none are active by default.
Stripe
Used for card payments and Stripe-powered payment processing.
What is sent: When a customer submits a booking using card or Stripe payment, the customer’s card details are tokenised entirely in their browser by the Stripe.js library (loaded from https://js.stripe.com/v3/ ) and a secure payment token is sent to your Stripe account via the Stripe API ( https://api.stripe.com ). Raw card numbers never pass through your server. The customer’s name and booking amount are also sent to Stripe to complete the charge.
When it is sent: Only when a customer completes a booking using Card or Stripe payment methods.
Stripe Terms of Service: https://stripe.com/legal/ssa Stripe Privacy Policy: https://stripe.com/privacy
PayPal
Used for PayPal Standard payment processing.
What is sent: When a customer selects PayPal as their payment method, they are redirected to PayPal’s website where they complete payment. The booking amount, your PayPal email address, and a booking reference are passed to PayPal. PayPal then sends an Instant Payment Notification (IPN) callback to your site to confirm payment.
When it is sent: Only when a customer clicks to pay via PayPal at checkout.
PayPal Terms of Service: https://www.paypal.com/us/legalhub/useragreement-full PayPal Privacy Policy: https://www.paypal.com/us/legalhub/privacy-full
Cash App
Used for Cash App Pay payment processing (US market only).
What is sent: When a customer selects Cash App as their payment method, they are directed to send payment to your configured $Cashtag. The booking amount and reference are displayed to the customer. No customer data is automatically sent to Cash App’s servers by this plugin — the customer initiates the transfer themselves through their Cash App account.
When it is sent: Only when a customer selects Cash App as their payment method.

Frequently asked questions.
Does upgrading the plugin delete my data?
No. The upgrade system uses dbDelta() which only adds missing tables and columns — it never drops or modifies existing data.
What industries are supported by the Setup Wizard?
Music Studio, Medical / Doctor Clinic, Hair Salon, Beauty & Aesthetics, Car Wash / Auto Detailing, Fitness / Personal Training, Dental Practice, Private Tutoring, Massage Therapy, Pet Grooming, Photography Studio, and Cleaning Services. You can switch industry at any time from Settings — it reloads seed data but never touches your real bookings.
What is the difference between the two booking forms?
[slotwise_booking_form] is the full form: the customer selects a service, level, duration, date, time, and pays.
[slotwise_package_booking] is the simplified form: the customer picks a package (which includes a fixed number of sessions at a fixed price), selects a date and time, and pays. No service or level dropdown needed. Is card payment PCI compliant?
Yes. The card form uses Stripe Elements, which tokenises card data in the browser. Raw card numbers never pass through your server.
Can I customise the appearance?
Yes — go to SlotWise > Appearance to change the accent colour, background colour, fonts, and font size. Changes apply instantly on all pages that show the plugin shortcodes. The plugin also auto-detects your active WordPress theme colours on activation.
Are discount codes validated server-side?
Yes. Discount amounts are always recalculated on the server before any charge is applied. The discount code and amount from the browser POST are never trusted — the code is re-validated and the saving recalculated server-side before being applied to the payment.
