- Brochure sites : these can either be static or editable with various levels user engagement (login areas etc) and self managed through a content management system. Prices range from $1k to $5k depending on depending on features & requirements
- E-commerce site – integrated with a payment gateway such as Paypal, Stripe or banks like Barclays or HSBC. Prices range from $5k to $20k depending on features & requirements
- A progressive web application – when a website requires lots of bespoke functionality or processes it generally falls under the web application category. Prices range from $10k to $30k depending on features & requirements.
