Frequently Asked Questions

  • Do you think I need a new website??

    Well, chances are, if you are asking this question, then you probably know the answer. Your organization or business may not need the most cutting edge website, but its design should feel relevant and fresh. If your website is more than 5 years old, then the answer is most likely, yes, it’s time for a redesign. Also, if you don’t like the look of your website, why should your viewers feel any different?

  • The process I use to build your website takes a certain amount of time and a lot of planning and research. Unlike other agencies, I DON’T use templates. I build your website from scratch, which means you get a unique design tailored around your business. Buying a website from me should not just simply be seen as a business expense as your website is a sales tool that should earn you money.

  • Before we begin working together, we’ll usually have an initial chat on the phone or via Zoom or whatever is suitable for both of us to discuss the project. Once we get started, most of the communication will take place over email. This makes the process a lot easier as we’ll have all of the information saved and can come back to it later. Once I’ve finished the development process of the project, we will have a test session together and make revisions if necessary.

  • It really depends on what type of website you want. We’ll be able to discuss this on our discovery call before we start working together. Depending on which package you select I could need…

    • Images of you and your team
    • Images of your workplace
    • Content for the website e.g. text, videos PDFs etc
    • Logo
    • List of custom functionalities
  • Before I build your new website, I'll design a mockup of the pages. I’ll design a layout in Photoshop first, that way you’ll get to see our initial designs within approximately 3 days. This is your opportunity to give us feedback and if you really don’t like it, you don’t have to move forward. Best part is, this won’t cost you anything.

  • Yes, I split the payment into two. The first 50% is usually taken once you have seen the mockup of your homepage and you’re happy to move forward. The following 50% is taken 2 days before the deadline we will fix.

  • Yes, you get 1 year free hosting service on all packages. You'll receive a reminder 1 month before the end of the free hosting period to upgrade to a paid service, or to prepare for a website migration to an other service. If you fail to upgrade to a paid service, your website will be automatically shutdown.
