Frequently Asked Questions

How long does a website take for a Mission business?
A custom site takes 4–10 weeks including design rounds and content; e-commerce 8–16 weeks. If an agency promises a custom site in one week, it's a template with your logo on it.
What does ongoing maintenance cost?
$50–$300/month depending on the stack, covering updates, backups, security and small changes. It's optional — you always own the site either way.
Do you build AI automation for Mission companies?
Yes. AI workflows, voice agents that answer your phones, and chatbots trained on your business — from $1,500. Mission service businesses use these to answer every lead within minutes, around the clock.
