With invoice immutability being pushed on us, we really need a way to properly calculate taxes before invoices are published and can't be changed any more. There are multiple areas in the world where WHMCS's tax rules are too limiting, but there is no tax calculation hook where addons can overwrite the incorrect tax calculations. A simple hook that we can use after WHMCS calculated its taxes (for orders and invoices) where we can overwrite the tax calculations is all that is needed so tax compliance is not limited as much by WHMCS any more. As a user, if you need to have taxes calculated differently, please vote at https://requests.whmcs.com/idea/hook-for-tax-calculation_1 to convince WHMCS to implement a way to have the option to have any taxes you need calculated by an addon at least. WHMCS: This shouldn't take too long to program and document, and if you only have one new subscriber because they can use your system now, it'll pay for itself.

18 years later and still not resolved. If you came here looking for a solution, please vote at https://requests.whmcs.com/idea/hook-for-tax-calculation_1 to convince WHMCS to implement a way to have any taxes you need calculated by an addon at least.

Clearly a need for a feature request. 😇

The demand is there. This needs to be developed in your latest version.

@WHMCS John I agree. There has to be an upgrade process. Making it harder for customers and business owners is not the right answer.

@WHMCS John If you want this to be the new default Stripe module, a migration path from the current default Stripe module will be necessary.

1. Deal of the Week: Proxmox VE VPS & Cloud For WHMCS 4.3.0 Not every module gets to call itself a long-time #1 bestseller. Our Proxmox VE VPS & Cloud For WHMCS can, and it has just welcomed a fresh round of improvements! Among the highlights of version 4.3.0, you'll find: Change Password is now available as a service action button for VPS and Cloud services, making password updates much quicker for clients.

We've got you covered - our Installation Services are currently 50% OFF for both the updated modules and the rest of our marketplace too! 3. For everything that's not in the default package Most of you know us through our ready-made modules, and for good reason. After all, they've been a core part of what we do for years. But what many may not know is that we also spend a good deal of our time building custom software around platforms like cPanel, Plesk, DirectAdmin, Enhance, and HestiaCP. Why? Because every now and then, a business needs something that isn't quite there yet. Maybe it's an integration you've always wished existed, a process that's still more manual than it should be, or a feature that would make everyone's day just a bit easier. So if there's something you've been wishing your software could do, we'd be happy to discuss it. Our Software Advisors can help you explore the options and see whether a custom solution could be the right way forward. Let's make your custom idea happen! 4.

Yep. That'll be it. These credit notes don't respect transaction actions.

@AbsoluteLocal You are in the wrong site. Send your issue at https://secure.5cloudhost.com/submitticket.php?step=2&deptid=1 or other offline option they got. This community (and WHMCS) will not assist you for a third-party provider.

It's actually very easy to fix whmcs' importassist addon, but the addon is encrypted so I can't close the bug and fix the flow for importing from the blesta database which has lots of column and table relation name errors.

Not as a transaction, but a credit note. Maybe that's the difference here. No transaction recorded for it.

They are. They rely on the domain's next due date in WHMCS - but they Domain Sync changes the next due date if the expiry date with the registry doesn't match the value in WHMCS.

Credits (including the new credit notes) have changed it seems. When you look at the invoice that was paid by the existing credit does the credit payment appear as a transaction at the very bottom of the invoice? Also checkout the Transaction tab for this client. It seems that the payment gets processed but the renewal 'action' remains pending.

Never once happened to us here, that the due date in domainsync was "changed" to the same date, nor that it was seemingly triggered to be correct by marking the renewal task as completed (it was delayed by investigating this time). Weird. I'd have assumed invoices are separate and didn't rely on registrar reporting.

This is not a result of upgrading to v9. It has always been like that. If client pays an invoice for domain renewal, the next due date and expiry date is updated automatically by WHMCS. When WHMCS runs the Domain Sync task, it queries the registrar for domain details and it finds the expiration date is now inconsistent, so it changes it. This also updates the next due date. It has been like that for as long as I can remember.

More information and download: https://soluzioniphp.it/en/info/sumup-module-for-whmcs.html Feedback and suggestions are welcome.

It wasn't until I marked the task of renewing it as completed did it update the next due date. That really should not be relying on domain renewal, if it's setting the next date to invoice. Way less reliable than "invoice paid, increment next due date".

It sounds like your Automation Settings include DomainSync and Sync Next Due Date, which query the registrar, if supported, to generate these values. If so, the registrar might have been reporting the expiration date incorrectly or the domain was not successfully renewed at registrar.

Hi all, I just wanted to advise that we are currently aware of another issue with MS365 authentication, which we believe is caused by a recent change that was made on Microsoft's end. If you see a blank page after completing authentication with MS365 upon being redirected back to WHMCS's callback, it is most likely caused by the Cross-Origin-Opener-Policy (COOP) enforcement in your browser. It'll look like this: A case is open to get a solution implemented on our end, but in the meantime there is a workaround. Sadly, Chromium based browsers (Google Chrome, Brave, Edge, etc.) enforce COOP usage and do not provide a way to disable it. However, it is possible with Firefox, though you should only do this temporarily, as COOP is an important security feature. Open Firefox, navigate to about:config, search for browser.tabs.remote.useCrossOriginOpenerPolicy and set it to false. Once that's done, you should be able to complete the auth flow as expected. Once you've done that, make sure you re-enable COOP by setting that flag to true again. As always, feel free to reach out to our Support team via ticket if you continue to experience issues.

We've migrated from CentralNic to OpenProvider, and it's been mostly without issues. We've had to contact OP support a few times but have almost always gotten a quick reply. Their WHMCS module is fine. It needs work here and there but they're open to suggestions - and their entire module is open source so anyone can make PRs. I've submitted a few and got them approved. Their API can be slow from time to time, but this was also an issue with CentralNic. Unfortunately, OpenProvider's API has a few more stability issues than CentralNic's. Switching to OpenProvider won't necessarily release you entirely from the hands of CentralNic, though. OpenProvider use CentralNic for a lot of TLDs - but OpenProvider's pricing generally better, even for those TLDs.

Marked the task as done, and on the domainsync that followed it updated correctly. One would have thought paying the invoice would be the trigger for updating the next invoice due date. Strange.

Moved to v9, we encountered an odd issue today. We manually process domain renewals after invoices are paid. Overnight, an invoice was generated for a domain, and fully paid by credit. A few hours later, the domain sync cron ran and gave me this: domain.tld: Next Due Date updated to 06/29/2026 (domain obscured for this post). That was the original due date, and having just been paid a few hours earlier, this should have been updated to next year. This is how it had always worked before v9, and system date is accurate. I've since manually renewed (which incremented the expiry correctly), and will monitor the next domain sync(s) to see if that changes, but it's really odd in that a paid invoice should trigger the due date, not renewal status, no?

Hi @hmaddy Have you opened an invoice? The added credit and debit notes should be displayed directly on the invoice.

No, php 84 will be available in future releases
