  • Description
    Do you want to elevate your brand? We're here to assist you in developing an app that prioritizes the needs of your users.

    Out-of-the-box software does not always provide the desired solution or is overly complex, making it difficult to use. Web applications, or custom online software, are the ideal option. Custom software has the advantage of completely matching the requirements of your staff, organization, and/or consumers. For increased productivity, cost savings, and user-friendliness, we deliver custom software that is perfectly matched to your business process.

    By flawlessly aligning your needs and combining them with our 'top of the range' skills, our dedicated team will become an extension of your organization. We can assist you with your most complex (unique) requirements as well as your greatest digital fantasies.

“They’re really helpful and quick to respond.” Project summary: Flatline Agency has provided web design and development services for a high-end jewelry company. They’ve completely redesigned the WordPress website and created an ordering system for B2B and B2C clients. Feedback summary: The website is ready to launch, and external stakeholders have given excellent feedback. Flatline Agency has designed a site that’s straightforward and easy to navigate, and the team stands out for their responsiveness. Overall, they communicate well through WhatsApp, Slack, and emails. OPPORTUNITY / CHALLENGE We needed to completely redesign our website and ordering system for the B2B clients. We hadn’t updated our site since 2015, so the main challenge was to get everything up to date with the latest trend and create the whole ecosystem behind it for our B2B and B2C clients. SOLUTION What was the scope of their involvement? We initially provided Flatline Agency with our guidelines and all our brand stories. They started by asking us questions about who we wanted to target and made a persona. Additionally, they researched trends. The team has developed the website on WordPress and used some plug-ins for the site. However, they’ve mainly created custom code. They’ve also advised us on cybersecurity, handled the testing, and provided maintenance services. What is the team composition? We have direct contact with eight teammates, including a co-owner, a project manager, and some developers. How did Flatline Agency perform from a project management standpoint? It’s been easy to communicate with them; we use WhatsApp, a Slack channel, and emails. They’re very responsive; it doesn’t matter if it’s 11:00 p.m. or 6:00 a.m., they always respond within a few minutes and answer our questions. Overall, giving them feedback is easy because they have their own spreadsheet for comments. What did you find most impressive about them? They’re really helpful and quick to respond.
