I was recently asked to update a website that was built using software native to the previous developer’s machine. Unfortunately, I do not own this software so I cannot take over the site as it sits. This is exactly why I encourage people to have their sites built with web based software such as WordPress or Squarespace, etc. It’s important to realize that your existing developer may not be around for the life of your business and you may need someone else to update your website. Ask your developer to make the change while they’re still your site service provider.
