This is where quotes get tricky. These items are often extra, but not always made clear upfront:
Ongoing hosting. Your website needs to live somewhere. Hosting costs anywhere from $10 to $50 per month depending on your needs. Some developers include the first year, others don't. Ask.
Domain name. Your web address (like yourbusiness.com.au). Usually around $20-50 per year. You should own this yourself, not have it in the developer's name.
Content writing. The words on your site. Many developers assume you'll provide this. If you need someone to write it for you, that's usually extra. Same goes for editing or restructuring content you provide.
Photography. Professional photos of your business, team, or products. Stock photos can work in a pinch, but they won't look as good as the real thing. If you need a photographer, budget for it separately.
Future updates. Once the site launches, you might want to change things. Add a new service page, update your prices, add team members. Some developers include a few hours of updates, others charge hourly. Clarify this before you sign.
Advanced features. Online booking systems, e-commerce, member logins, custom calculators. These add significant time and cost. If you need them, make sure they're in the quote. For more on costs, see how much a website costs in Gippsland.
