Grow CRM allows you to set up your own SaaS business. You can create free or paid plans. Your customers will have their own instance of the CRM, running on a subdomain (example: customer.yourdomain.com). For maximum efficiency, each account will have its own database. You will be able to accept payments via credit card(Stripe, Paystack) or via Paypal. You can also access offline payments.
It also comes with a beautifully designed landing page and a content management system for you to edit the content of the landing page.
