Every module recommended for the one you already have in your shopping cart now comes with a $10 discount, and when you go for an Open Source product, you receive $25 OFF on top!  What makes this even better is that these discounts work together with our Deal of the Week, Deals of the Day, and every single promo code that comes your way. It is entirely possible to combine up to four discounts at once! If you feel like exploring what those new discounts could look like for you, here is a 5% promo code as a starting point for your own experiments: Promo Code: 5%Mix&Match Sometimes the best configuration is the one you discover by mixing!

Discover how flexible ontract logic can look in practice!   3. Google Analytics For WHMCS 1.2.0 - 25% OFF You probably have access to plenty of data already. Orders, invoices, support history. Yet understanding how customers actually move through your system is a different story. Google Analytics For WHMCS was designed to connect those dots. By sending structured WHMCS data directly into Google Analytics, it allows you to analyze behavior across the full purchasing journey. Its latest release, version 1.2.0, ensures full compatibility with WHMCS 9.0.1. You can observe where interest turns into action, where users pause, and how different steps influence conversion. Instead of relying on assumptions, you gain measurable insight that can guide real improvements. For less than 48 hours, the module can be ordered with a massive 25% discount!

WHMCS 9.0 marks a new stage for the platform, and for many teams it naturally raises a broader question: what should evolve next? If you have been thinking about custom software development, whether that means building something entirely new or refining what already exists, this season offers a practical incentive. Our Winter Promotion provides up to 30% OFF custom projects! The deal covers: Brand-new WHMCS modules, Tailored extensions to our existing products, Updates that bring older custom projects in line with WHMCS 9.0.1.

EasyDCIM v1.24.0 with Provisioning Profiles for OS Installation As infrastructure grows, OS installation logic tends to accumulate complexity. EasyDCIM introduces a structural answer to that challenge in the form of Provisioning Profiles. Instead of embedding all installation logic directly into templates, you can now separate it into reusable, clearly defined components. Beyond this core enhancement, the 1.24.0 release also: Expands PDU Management with support for ServerTech STV 4511C devices, Enables custom VMware ESXi installation templates from vendor specific or custom ISO images, Adds automated installation support for Fedora 43 Server. With each release, the path toward EasyDCIM 2.0 becomes shorter. The direction is clear, and the practical benefits are already visible in daily use. Separate your OS provisioning logic and make it easier to maintain!   7. PanelAlpha v1.7.0 with the WordPress Migrator Plugin WordPress migrations are rarely scheduled at convenient moments. They often appear suddenly, under pressure, and demand reliability more than anything else. PanelAlpha approaches migrations from a practical perspective. The new Site Migrator Plugin brings automated transfers handled entirely within the PanelAlpha dashboard, reducing the need for manual coordination between environments. You can choose a plugin-based workflow by providing wp-admin credentials or installing the plugin manually on the source site. For more complex scenarios, the FTP/SFTP method remains available. Larger databases and media heavy installations are handled through asynchronous transfers, improving stability during the process. At the same time, PanelAlpha Engine has been updated with broader PHP support, enhanced security measures, and stability improvements across web servers and background services. Together, these updates turn daily tasks around WordPress hosting into something you can plan calmly instead of react to under pressure. If site transfers regularly land on your to-do list, PanelAlpha v1.7.0 should make them far easier to handle. Try the new Site Migrator Plugin and streamline your next migration!   Need WHMCS Module Development For Your Business? Get Your Free Quote Now!

@WHMCS John I have identified another issue introduced with the latest update. I have a client who owns two different products with different due dates, which resulted in two separate invoices being generated with different due dates. Both invoices passed their due date and, as expected, a 2% late fee was applied to each one. The client then used the "Mass Payment" option, selected both overdue invoices, and completed the payment. However, during this mass payment process, the late fees were not charged at all. Only the original invoice amounts were paid. As a result, both invoices remained partially unpaid with the pending late fee balance, and the services were not renewed. I only became aware of this issue because the system automatically suspended a client’s service even though the client had already paid what was presented during checkout. In practice, the payment flow allowed the client to pay the invoices without the late fees, but the system still considered the invoices as open due to the remaining interest amount, preventing service renewal. This creates a serious inconsistency, as the client believes everything is paid while the system does not finalize the invoice correctly.

Merhabalar, Arkadaşlar geçenlerde bir konuda Whmcs TR karakter sorununu çözümünü bulamamıştık herkes geçici çözümler söylemişti. Konu hakkında kalıcı bir çözüm ürettim kullanmak isteyen kullnabilir dilediği gibi. Öncelikle bu konu hakkında Whmcs tarafında bir makale paylaşılmış ben yeni denk geldim belki denk gelen vardır bilmiyorum. Kısacası Whmcs diyor ki Sunucu tarafında nginx apache htacess vb işlem yapmanıza gerek yok basit bir hook ile sorunu çözebilirsiniz. bu Hook dosyasını yazdım kullanmak isterseniz; Whmcs kurulu olan dizinde: includes/hooks/transliteration_tr.php dosya oluşturup içine aşağıdaki kodları yerleştirin <?php /** * WHMCS Türkçe Karakter Transliterasyon Hook * URL ve Modül verilerindeki karakterleri otomatik dönüştürür. * Ali Comez */ function hook_transliterate($string) { $search = array('ç', 'ş', 'ğ', 'ü', 'ö', 'ı', 'Ç', 'Ş', 'Ğ', 'Ü', 'Ö', 'İ'); $replace = array('c', 's', 'g', 'u', 'o', 'i', 'C', 'S', 'G', 'U', 'O', 'I'); $string = str_replace($search, $replace, $string); return $string; } Not: Bu hook dosyası eski URL'lere birşey yapaaz zaten oluşturulmuştur. yeni oluşturulacak olan URL'ler için geçerlidir. Eski URL'lerin dönüşümü için bilgi bankası veya duyurularınızı yeniden düzenleyip kaydetmeni gerekiyor ki whmcs bunları yeniden oluştursun. Sağlıcakla kalın...

php versions have never changed, nothing has changed

Here is the procedure we followed to replace the `vendor` folder. 1. Renamed the Existing Folder We renamed the current messy `vendor` directory to separate it from the live site without deleting data. mv vendor vendor_old   2. Deployed the Fresh Folder We extracted the clean `vendor` directory from the **WHMCS v9.0 Full Release** zip file and placed it in the root directory. unzip -q whmcs_v901_full.zip "whmcs/vendor/*" mv whmcs/vendor ./ rm -rf whmcs *(If you did this via FTP, you simply uploaded the fresh `vendor` folder to `public_html/`)*   3. Safety Retention Do not delete `vendor_old` yet. Keep this folder on the server for several weeks. If any custom modules or hidden dependencies break in the new environment, we can reference or restore files from this backup. Once the system is confirmed stable after a few billing cycles, you can remove it.

Yes, I agree they should be an option 

Hi, I have the same problem, did you find the solution??   

The user is getting the WHMCS error Domains must begin with a letter or a numbeR even though the domain format is correct. This message usually isn’t about the domain itself it often happens when there’s missing domain pricing for the currency being used or a configuration issue with the domain pricing setup in WHMCS. It’s recommended to check Domain Pricing in System Settings and make sure all TLDs have prices in every currency you offer, otherwise WHMCS shows this confusing error.
