We personally love WhatsApp when it comes to forms of communication. Payment terms we're super flexible. We quote our proposals on an hourly rate but are more than happy to break it up in milestones. Whatever the client wants we are more than happy to do. When we finish each milestone or app project our Net 30 terms go into play. Which means if we don't receive payment within the 30 days a late fee will be added to the project.
Our team is super flexible with anything that we do. We're constantly going to be communicating with you through out the project to build your trust and most importantly develop the app you want developed.
