Stay with Thryv if
Stay with Thryv if you use the platform, not the page. The customer database, appointment booking, messaging, invoicing and listings management are the reason people pay for it, and the website is bundled alongside them. Cancelling the platform to change your website would be an expensive way to buy a website.
Stay if the Starter tier is doing the job at $99 a month. If you build your own pages, keep them current, and only need the site to exist, adding a separate website relationship is spending money to solve a problem you do not have.
