PD SMS Manager for WHMCS

PD SMS Manager adds text messages to WHMCS as a proper notification channel. Your clients get a text when an invoice is created or paid, when a service is activated or suspended and when staff reply to a ticket. You and your team get a text when a new order lands or something fails to set up. You can also message a filtered group of clients in one go. Every message goes through your own SMS provider account, and you pay that provider directly at its own rates.

It is built for hosting companies who know that a missed email is a late payment or an avoidable ticket, and who want the one channel people actually read at the moments that matter. Its biggest difference from a single-provider SMS module is that you are never tied to one carrier: you connect as many gateways as you like and choose which one carries each kind of message.

Why hosts choose PD SMS Manager

One module, every provider you might use. Amazon SNS, Azure Communication Services, Twilio, Vonage, Clickatell and any gateway with an HTTP API are all supported in one place, plus a Test gateway that sends nothing. Add several at once and mark one as the default. A single-provider module means a rebuild if you change supplier or need a second route. Here, you add a gateway and carry on.

Send each kind of message down the right route. Every trigger and every campaign can name its own gateway, or use the default. Put payment and security texts on a dependable transactional route, and promotions on a cheaper one. If a provider has an outage, you can point a trigger at another gateway without touching anything else.

Pay your provider, not us. No message credits are sold and nothing is marked up. Your provider's own rate is the cost of every text, and the segment counter shows what a message will cost before you send it.

Reach people at the moments that matter. Triggers send automatically for invoice created, invoice paid, service activated, service suspended or unsuspended, ticket replies, failed domain renewals and sign-ins to an account.

Stay on the right side of consent. Clients choose which kinds of text they receive, promotional texts are agreement-only by default, and an opt-out made while a message waits in the queue is honoured.

Text-message sign-in. The same gateway can send one-time codes as a second step at sign-in, for your clients and for your own staff, with no separate service to buy.

How it works

1. Connect a gateway. Go to SMS Manager, then Gateways, and add your provider with its credentials. Test connection checks them without sending anything. Send test SMS delivers a real message to a number you give.
2. Set the basics. Choose a default sender ID, which client field holds the mobile number, and whether to send through the queue.
3. Turn on the messages you want. Pick templates and map them to events, or leave them off and send by hand.
4. Watch it work. The dashboard shows what went out today and this month, and History records every message with its gateway and status.

What you get in WHMCS

Sending

• Send a one-off message to a client picked by name, email or client ID using the number on file, or to any number you type
• Count segments shows how many SMS segments the message uses before you send, counted the way providers bill: 160 characters for GSM-7, 70 for Unicode, with emoji and extension characters counted correctly
• Drop a saved template into the message on the Send screen and in the campaign builder
• Text a client from their own admin profile, which also shows the number we would use, where it came from and when you last texted them
• Numbers are converted to international format automatically, adding the country code from the client's country

Templates and triggers

• A library of templates grouped by category, each switched on or off
• Merge fields for first name, client name, company, invoice number, total and due date, product, domain, ticket subject and ticket number; an empty field is left blank, never shown as raw braces
• Triggers for invoice created, invoice paid, service activated, service suspended or unsuspended, staff ticket reply, failed domain renewal and client sign-in
• Each trigger can use its own gateway and respects the sending queue

Campaigns

• Target clients by status and client group, and send now or schedule
• Preview audience and cost shows exactly how many clients a campaign reaches and how many segments it will cost
• Only clients who agreed to marketing texts are included, and progress shows sent and failed against the total
• Cancel a campaign and the unsent messages are dropped

Staff alerts

• Each administrator sets their own mobile number and the events that text them: new order, paid invoice, new ticket and cancellation requests, plus failures to provision, suspend, unsuspend, terminate or change a package, and failed domain registrations, transfers and renewals
• Alerts, manual sends and sign-in codes are never held by quiet hours

Running it day to day

• A sending queue that your WHMCS cron drains in batches, with retries for messages the provider rejects and optional quiet hours
• History with search and filters for status, gateway and date; open any message to see its full text, the provider's reference and any error, and resend it in one click
• Honest statuses: sent, failed, or unknown when a provider did not answer in time. No message is shown as delivered when it may not have been
• A Health report that says whether a gateway is ready, what failed this month and whether the queue is draining
• Test gateway: record messages in History without sending them, to try templates and triggers without spending credit

What your customers get

• A Text messages page in their client area listing recent texts and what they have agreed to, with a link to change it
• Preferences on their Account Details page, beside their email preferences, each with a plain explanation
• Simple, honest choices. A customer who unticks a category is not texted in it, even for messages already waiting
• Text-message sign-in, when you switch it on, with a countdown and a way to request a new code

The pages render on WHMCS's Six, Twenty-One and Nexus themes, and their wording can be changed in a file that survives updates.

Security built in

• Provider credentials are stored encrypted and never shown again after saving
• A disabled gateway never sends, even if a trigger names it
• Sign-in codes are stored hashed, and History records only that a code was sent. A code is destroyed after five wrong guesses, and one person can get at most one code a minute, so the sign-in page cannot drain your SMS balance
• If the sending engine is ever missing, sign-in is refused rather than waved through
• Number and message go only to the provider you connected. Nothing about your clients comes to us

One product, every feature

PD SMS Manager is one paid module with everything included: all gateways, triggers, campaigns, staff alerts, client preferences and text-message sign-in. There are no tiers. It installs into PD Modules in one click and uninstalls cleanly.

If your subscription ever lapses, your data is kept. After a 14-day grace period admin features lock, then customer-facing features stop, and automatic texts and campaigns pause until you renew, when the queue resumes and nothing is lost.

Requirements

• WHMCS 9 or later on PHP 8.2 or later, with the ionCube Loader and cron running
• An account with at least one SMS provider
• PD Modules, the free control panel every PD module installs into
