Thank you so much Bruno, for sharing your feedback. We’re truly happy to hear that our Proxmox Module is helping streamline your processes and provide greater autonomy to your clients. Your kind words mean a lot to our entire team and are a great motivation for us to keep improving and delivering reliable, high-quality solutions. We sincerely appreciate your continued trust and support since 2019. Thank you for being a valued client!

I've been working with this company since 2019 and, throughout that time, I've always received excellent service. They are attentive, reliable professionals committed to quality service. The Proxmox module is positively surprising us. It's a very functional tool that has been streamlining our processes and providing even more autonomy to our clients. We recommend the company and, especially, the purchase of the Proxmox module!

You should start by checking the WHMCS cron logs for the months where the invoices were missed, since a failed or delayed cron could explain the issue. Then check the client’s transaction and credit history to see what created the unexpected credit and when it was applied.

We are in the EU, but we use WHMCS invoices as "pro forma" and create the "real invoices" later via our central ERP system. The latest update is not suitable for us...

Shame that advertising like this isn't allowed here, huh? 🤫

I can help you with this for a small fee.

Is there anyone who can guide me?

Two new ModulesGarden releases are now available for WHMCS users. Proxmox VE VPS & Cloud For WHMCS 4.4.0 The latest update introduces an entirely new Automations tool. It allows administrators to define triggers for events occurring in WHMCS and the module and connect them with predefined follow-up actions. Workflows can send notifications, open support tickets, create administrator tasks, execute commands, resize virtual machine disks, and launch other supported module operations. Individual automations can also be limited to selected customer groups. Version 4.4.0 additionally introduces centralized Connection Details management for server access credentials and smarter control over which package changes require a virtual machine reboot. Explore the release: https://www.modulesgarden.com/blog/proxmox-ve-vps-cloud-for-whmcs-4-4-0/ Anti-Fraud & Email Verification For WHMCS 1.0.0 Our new module provides an automated way to verify client email addresses and reduce unwanted activity in WHMCS. Verification may be required during checkout or before access to the client area. Clients can confirm their addresses through a clickable email link or a manually entered code. The module also includes CAPTCHA protection, request rate limits, automatic bans, and blocklists for email addresses, domains, and IP addresses. Configurable reminders and lifecycle rules help manage accounts that remain unverified. Administrators can monitor verification records, review recent activity, manage statuses, and follow related events through detailed logs.

Hi, Since the update with Invoice immutability was introduced it has caused us major issues with automatically generated credit notes. Example, customer domain renewal expires, they paid it a week later, the system automatically generates the credit note (even though I didn't want it) There's no way to delete the credit note. Then when the next invoice is generated the credit note deducts the amount off their invoice even though the customer has fully paid the first invoice. Is there a way to stop the automatic credit note generation as this doesn't work with our workflow? Thanks in advance.

I also have the same question because this looks like it could be related to how the different support department email addresses are authenticated or associated with the SMTP account. It seems that the support address can send successfully because it matches the SMTP account, while addresses such as sales, billing, abuse, and general are being rejected when the system tries to use them in the `MAIL FROM` command. The 550 message specifically mentioning that `support@example.com` cannot send emails from `sales@example.com` makes me wonder whether each department address needs to be configured separately or whether the SMTP server needs to explicitly authorize those sender addresses. I’d also be interested in knowing the recommended setup when multiple departments and users need to send replies from their own department addresses. If all four addresses are supposed to use the same SMTP account, there may be a sender-alias, mailbox, or permission setting that needs to be configured on the mail server. Since the same error is appearing repeatedly in the activity log, it seems like the application is attempting to send the message correctly but the SMTP server is rejecting the sender identity. Hopefully someone who has configured multiple support departments with separate From addresses can clarify what needs to be changed.

Actually, WHMCS has been doing it this way for at least 10 years… 😂

I added the setting to my config file to allow for invoice editing, but I notice the late fees still go into the "ledger" section without any type of label showing it is a late fee. And that section doesn't appear to be editable. How can I get back to being able to remove late fees?

Any chance of getting a copy? Sounds perfect for my needs too!

Thanks. If you have any questions we will be happy to assist you.

Have an email notifier to let me know of new tickets. I'd really like to have the name of the person who opened it included, but notification merge files in the "default" template don't offer that. Even the email of the client that opened it would be helpful if not the name. Currently I get only Ticket opened (with link) and by user # at the end of that user's link. Any way to get the user name or email also? Can't seem to find it. Admin email notification only.

Well its been 8ish months since release and about 55% of whats been released has been security fixes. I'm usually the first to update (including to beta), but I held back on 9.x, and I'm glad I did - Here we are 8 months on, and from the feedback it seems most are still recommending staying on the 8.x branch till fixes are implemented for all the invoicing issues and concerns. After you take security out, what is left is maintenance: ~1% of all post-GA updates is a new feature ~12% is billing correctness ~10% is making Nexus behave ~20% is module/platform plumbing and deletions What is in each bucket Billing / invoices / credits / reports (11) Downgrade credit calc, invoice chunking, invoice generation errors, cancelled services renewing by mistake, mass-pay late fees, late fees on 9.0 upgrade, admin invoice currency, billing notes excluded from income stats and cashflow, invoice-merge hook, Stripe admin capture logic. Platform / ops / compatibility (10) jms/serializer bump, ClassLoader error on update, Smarty-tag handling, S3 default region, Setup Tasks list, PHP-version health check, deprecated-module health check, Recaptcha error handling, activity-log error handling, persist Sign-In Integration notice. Nexus / theme / cart (9) Inclusive tax, renewals visibility, product deletions, domain addons, URL rewrites, path references, cart error handling, session handling in the Nexus theme, 360 Monitoring landing-page crash. Modules / integrations, not security (8) Plesk integration, suspend/unsuspend, and change-password updates; Enom variable name; Digicert SSL expiry; Stripe + Invisible reCaptcha errors; OAuth call errors; Sign-In Integrations handling. Removals (2) HipChat notification module; Asiapay, Gate2shop, Inpay, and Paypoint dropped from the package. New feature (1) Stripe Dynamic Payments in 9.0.3. If I had to guess, your development team is flat out using AI to plug all the big holes. If this is the case, great - Let us know. If this isn't the case, then very little has been done in the way of meaningful changes to the GA release. How bout decent passkey support - There is NO WAY im buying a third party addon for this.

Just a quick update, Lara v9.0.1 is fully compatible with WHMCS v9.0.8 (security update).

Hi there everyone I am lee im a software programmer from melbourne Australia

Interested in experiences migrating from self-hosted to cloud, especially regarding avoiding downtime, etc. Who's done this and can you share lessons learned? Thanks!

We are looking for an experienced Electron + React + TypeScript developer to build a custom desktop application for real-time event monitoring and bidirectional communication. Scope of work: • Implement two-way event ingestion through local sockets and daemon bindings. • Develop a secure authentication flow with key/credential handshake. • Maintain an immutable event timeline: deleted, retracted, dropped, or cleared records must remain visible as clearly marked archived placeholders rather than being removed. • Build a clean, modular and maintainable React interface. • Ensure reliable operation of persistent background streams within Electron’s IPC architecture. Requirements: • Strong commercial experience with Electron, React and TypeScript. • Practical experience working with long-running, high-availability background processes and real-time data streams. • Good understanding of Electron IPC and secure credential handling. • Ability to structure the application into clear, maintainable modules. If you have relevant experience, please share examples of recent projects or similar work. Include your Telegram contact in your private message.

Hi @azzepis, We have indeed included some maintenance updates to the Plesk module to address this in 9.0.8: WHMCS-27532 — Update Suspension and Unsuspension in Plesk WHMCS-27812 — Update Change Password in Plesk Whilst older versions won't be getting a similar update, you can grab the following files from the 9.0.8 patch set and upload them, overwriting the existing files: /modules/servers/plesk/templates/api/1.0.0.0/webspace_set_status.tpl /modules/servers/plesk/templates/api/1.0.0.0/webspace_set_password.tplwebspace_set_status.tpl These files aren't tied to a specific version of WHMCS, so will work with EoL and LTS versions.

Oh, sure. Why not, people don't need fully functional billing system, they need safe one! Good work, as always

Hi @azzepis, We do not currently plan to make these updates to the Plesk module in 8.13. 8.13 is currently in Long Term Support, meaning it receives critical security updates. Maintenance occurs in the General Availability release (currently 9.0). New features and continued compatibility updates - such as these - are, as much as possible, planned for new feature releases (9.1, 9.2 etc.)
