Custom CRM development

We build CRM systems around the way your team sells — by phone, email, Viber or in meetings. Customers, deals, quotes and conversations are all in one place, while tasks show who needs to do what. That is how Saitami ERP works too — our system with CRM, a built-in phone and PDF quotes.

What you get

  • Built around your sales process

    Deal stages, roles and quotes follow your sales process.

  • Quotes in PDF

    Quotes are generated as PDFs from customer data, just like in Saitami ERP.

  • Phone system built in

    Browser-based calls linked to the customer’s profile, just like in Saitami ERP.

  • Every customer channel in one place

    Email, phone, Viber and WhatsApp in the customer history, just like in the “Contact Center” demo.

  • Tasks and reminders

    Every sales rep can see what they need to do today.
