PD Google Cloud PostgreSQL for WHMCS

PD Google Cloud PostgreSQL lets a hosting company sell managed PostgreSQL databases as its own product. Your customer orders in your WHMCS cart, a dedicated Cloud SQL for PostgreSQL instance is created in your Google Cloud project, and your customer runs it from your client area: connection details, trusted addresses, databases and database users. Google bills you at cost, you set the price, and the difference is your margin.

It is built for hosts whose customers build on PostgreSQL, such as Django, Rails, Laravel and Node.js developers who want a managed database with a current version and no server to patch. You get the product without building a control panel, and your customers never need a Google Cloud account.

Why hosts choose PD Google Cloud PostgreSQL

Four supported versions to sell. PostgreSQL 18 is the default, with 17, 16 and 15 alongside it. Customers can pick a version at checkout, or you fix it per product. A blank setting uses 18, and the setting says so, so you can keep older projects on the version they were built for.

A dedicated instance for every order. Each order gets its own Cloud SQL instance and its own credentials, created in the region the customer chose from more than 40 Google Cloud regions. Nothing is shared between customers.

Orders set themselves up. A paid order creates the instance with no step from you. It is built in the background and the connection details appear on their own once Google reports it running. If a create fails, Google's reason is shown in the service's activity, and the order is never left spinning as "creating".

Less support for you. Trusted addresses, databases, database users and password changes all live on the customer's own service page.

Nothing left billing. Terminating a service deletes the instance and the module confirms it is gone, even when your licence has lapsed.

Your Google account stays yours. The service-account key is stored encrypted on your WHMCS server and never reaches a customer page or message.

How it works

1. Connect your Google Cloud project. Create a service account with the Cloud SQL Admin role, paste its JSON key into a WHMCS server record and press Test Connection, which makes one read-only call. A missing role, a disabled API, a project without billing, or an organisation policy that blocks key creation is named in plain words, with the Console path and gcloud command for the policy.
2. Create your product. Set a default region, plan, PostgreSQL version and storage, then generate the cart options in one click: Region, Plan, Engine version and Storage. Generated choices start at zero for you to price.
3. Your customer orders. They choose their options at checkout and pay. The instance is created and named with your prefix. Until it is ready the customer sees a "being set up" message, not an error.
4. You get paid, they manage it. WHMCS keeps billing. Plan and storage upgrades use WHMCS's own upgrade flow.

What you get in WHMCS

Selling and pricing

• Cart options generated for you and linked to the product: Region, Plan, Engine version and Storage
• Choose which options customers see; hidden ones are fixed to your product setting
• Prices you set survive a sync. Rebuild from Google Cloud re-reads the catalogue and warns that prices return to their starting value
• Plans from shared-core db-f1-micro and db-g1-small up to db-custom vCPU and RAM sizes, from a catalogue curated against Google's published lists
• Storage from 10 GB, which can be sold as an option
• A name prefix on every instance, so names read as yours

Provisioning you can trust

• Running Create again never builds a second instance; the recorded one is reused
• Upgrades and downgrades resize the instance in place and keep the data. Storage grows in place and a smaller size is refused
• A plan and storage change together applies both
• Changes to one instance are applied one at a time, and a request that arrives mid-change is told to try again in a minute
• Suspend stops the instance and keeps the data. A suspension that arrives while Google is busy is queued rather than dropped. Google still bills storage for a stopped instance, so terminate to stop all billing
• An instance deleted directly at Google is detected and flagged to you, without changing your billing

Running it day to day

• Clients and Databases lists every instance against its service, with its state
• An activity log of provisioning, upgrades and password resets, each with its outcome
• Read-only assistant tools report a service's instance, engine, version, size, region and state, list your databases and show recent provisioning. They cannot create, resize, delete or restore anything

What your customers get

• Connection details to copy: host, port 5432, the postgres login, a password to show or copy, and a ready psql connection string. Connections can use SSL/TLS
• Trusted sources: a new instance accepts no connections until the customer adds an address. They manage the list, invalid entries are refused with a message, and changes apply within a minute
• Their own databases, created and dropped from the client area, with system databases protected
• Their own PostgreSQL users with passwords they choose; the postgres login and system accounts are protected
• A new postgres password in one click, shown in the connection details
• Recent activity with the outcome of each action
• Confirmation first in an in-page dialog before anything destructive

Each section is a switch on the product: Firewall, Connection details, Users and Databases. Switch one off and the customer cannot see it and the server refuses it. The pages render on WHMCS's Six, Twenty-One and Nexus themes and are fully translatable with wording overrides that survive updates.

Every instance is created with automated daily backups and point-in-time recovery switched on. Restores are done by you in the Google Cloud console; customers ask you.

Security built in

• Your Google key is encrypted on the server record and never shown to a customer.
• Each database password is stored encrypted and shown only to the signed-in owner.
• Customer actions need a signed-in owner and a valid security token.
• Failures on your side, such as a missing role or a policy, show the customer a neutral message and put the detail in your log.
• Customer data, credentials and connection details are never sent to us. Only Google's Cloud SQL Admin API and the licence check are called.

One product, every feature

PD Google Cloud PostgreSQL is one paid module with everything included. There are no tiers and no per-instance fees to us; you pay Google at cost and keep the margin. It adds its own tables and templates, leaves WHMCS files alone, and uninstalls cleanly.

If your subscription lapses, your customers' databases keep running. The module never stops, deletes or alters an instance. New provisioning and your management screens are withdrawn while read-only visibility stays, and everything returns once you are in good standing.

Requirements

• WHMCS 9 or later on PHP 8.2 or later, with the ionCube Loader
• A Google Cloud project with billing and the Cloud SQL Admin API enabled, and a service-account key with the Cloud SQL Admin role
• PD Modules, the free control panel every PD module installs into
