The business

Zinen Technologies is a software company at Bazaar Plaza on Moi Avenue, Nairobi, led by its director, James Mwangi. It sells business systems to companies across East Africa: ERP, point of sale, websites, networking and CCTV.

Selling systems like these runs on paperwork: a quotation first, then an invoice, then the payment.

What they set up

Zinen runs those three steps through WhatsApp on Haiya:

Quotations are handled on WhatsApp.
Invoices are handled in the same chat.
Payments are received through Haiya.

Every one of those chats sits in Haiya’s shared inbox, where the whole team can see it.

The results

Zinen Technologies’ numbers are not on this page yet. When they are, each one will say which months it covers and how it was measured.

At Zinen Technologies Ltd we use Haiya every day, and it has made team communication much easier. When a WhatsApp message comes in, we assign the lead to the right team member. From there, they can create a quote, send an invoice and even request payment through M-Pesa, all in one place. This has helped us a lot. We’re very satisfied and looking forward to more features.
