What You Will Build

By the end of this guide, you will have a working WordPress-as-a-Service platform where visitors can self-service sign up, pick a site template, choose a plan, and receive a fully provisioned WordPress site.

Tutorial Goals

Component	What you will set up
Plans	1 free plan (basic features, no payment required) + 1 paid plan (monthly via Polar)
Billing	Polar as primary payment provider
Templates	At least 1 site template customers can choose from
Frontend	Signup page, template browser, tenant dashboard
Flow	End-to-end: visitor → select template → pick plan → pay (if paid) → site created

Customer Signup Flow

Here is what your customers experience:

Visit signup page - sees available plans and pricing
Pick a template - browses the template gallery with tags/filters
Choose a plan - free or paid
Enter site details - subdomain slug, email
Pay (if paid plan) - redirected to Polar checkout
Site provisioned - customer receives their WordPress site URL
Access dashboard - manage site, billing, custom domain, backups

What Each Plugin Does

GrabWP Tenancy (Base)

The foundation. Handles tenant routing (subdomain → correct database tables), table-prefix isolation, and basic tenant management. Every tenant shares the same MySQL database but has isolated tables.

GrabWP Tenancy Pro

Adds advanced isolation and management:

Dedicated databases - each tenant gets its own MySQL database or SQLite file
Content isolation - separate themes, plugins, uploads directories per tenant
S3 storage - offload uploads to cloud storage
Backup & restore - per-tenant backup and restore
Tenant cloning - create templates by cloning existing tenants

GrabWP Tenancy WaaS

The self-service layer that turns your WordPress into a SaaS platform:

Plans - define free and paid tiers with features and pricing
Billing - Polar and WooCommerce integration for payments
Templates - template gallery with tags, groups, and plan restrictions
Signup flow - complete provisioning pipeline from signup to site delivery
Tenant dashboard - customer-facing dashboard for site management
Custom domains - let customers use their own domains
Subscriptions - lifecycle management with grace periods
