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:

1. Visit signup page — sees available plans and pricing
2. Pick a template — browses the template gallery with tags/filters
3. Choose a plan — free or paid
4. Enter site details — subdomain slug, email
5. Pay (if paid plan) — redirected to Polar checkout
6. Site provisioned — customer receives their WordPress site URL
7. 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
