Accepting Payments in WHMCS 8.x in Israel: Tranzila Tokenization & Automated Tax Invoices

Hosting providers, cloud platforms, and digital agencies in Israel rely on WHMCS to automate recurring billing, domain renewals, and service provisioning. However, connecting WHMCS to an Israeli clearing processor like Tranzila presents two local engineering challenges: handling 3D Secure and recurring card tokenization on modern PHP 8.1+ servers, and issuing compliant Israeli tax invoices (חשבונית מס / קבלה) strictly upon payment capture. Here is how our Israsky Tranzila for WHMCS module solves both out of the box.

1. PCI-Safe Iframe, 3D Secure, and Recurring Card Tokenization

For subscription businesses, customers expect to enter their card once and have monthly or annual renewals processed automatically without storing raw card numbers on your server:

• Hosted Iframe & 3D Secure verification: initial card entry takes place inside Tranzila’s secure iframe with full 3DS support.
• Automated token charges & admin refunds: WHMCS stores only the encrypted Tranzila token, enabling the daily billing cron to charge renewal invoices automatically and allowing administrators to trigger partial or full refunds directly from the WHMCS invoice screen.

2. Automated Israeli Tax Invoices (חשבונית מס / קבלה) on Capture

Under Israeli tax regulations, the pro-forma invoice generated by WHMCS prior to payment serves only as a payment request (חשבון עסקה). A legally signed tax invoice and receipt (חשבונית מס / קבלה) must be issued only after the transaction succeeds.

Israsky Tranzila for WHMCS automatically triggers Tranzila Invoices upon successful payment capture, passing line items, VAT calculations, and automatic USD / EUR to ILS currency conversion at checkout.

3. Off-the-Shelf Gateway Module vs. Custom WHMCS Engineering

For standard WHMCS 8.x installations, our ready-made module covers the complete billing and invoicing lifecycle immediately.
