I'm using Paylink by PointCheckout in UAE, which generates a payment link which I can send via email/SMS and WhatsApp

Most of our clients don't provide their email address and even for those who do, the lead time to payment is much longer compared to when we send our clients the payment summary and attach the PDF invoice over WhatsApp, which is why we don't integrate to 'regular' payment gateways as they automate sending the invoice and payment link over email (which isn't what we need) 

I'll have a poke at the exporter tool - thanks!
