India GST Invoicing for WHMCS
GST tax invoices from WHMCS: CGST + SGST or IGST worked out by state, GSTIN checks, SAC codes, financial-year invoice numbers and GSTR-1 exports.

Tap Payments for WHMCS connects your WHMCS to Tap, the payment gateway used across Kuwait, Saudi Arabia, the UAE, Bahrain, Qatar and Oman. Your clients pay invoices with the method they already use at home.
Clients pay on Tap's secure page with Visa, Mastercard, American Express, mada, KNET, Benefit, Apple Pay and the other methods enabled on your Tap account. Card details never touch your server, 3D Secure is handled by Tap, and the page opens in English or Arabic.
When the client returns from Tap, or when Tap notifies your WHMCS directly, the module asks Tap for the payment and credits the invoice only for a payment this WHMCS created, and only once. Nothing has to be configured in the Tap dashboard.
Open the invoice, choose the transaction and press "Refund through Gateway" — in full or in part. No need to sign in to Tap.
Tap supports AED, BHD, EGP, EUR, GBP, KWD, OMR, QAR, SAR and USD. For clients billed in another currency, pick one of these under the WHMCS setting "Convert To For Processing" — the invoice is still credited in its own currency.
Upload the module, activate "Tap Payments" under Payment Gateways, paste one secret key and save. A test key takes test payments; switch to your live key when you are ready.
You need your own Tap account. Clients pay each invoice on the Tap page; cards are not stored for automatic recurring charges.
