Choose a category on the left, tick the features your project needs, and watch the live preview and total update on the right. Some features automatically bring in what they depend on — for example, PayPal needs a cart, a dashboard and an admin panel to work properly, so those are added for you.
Estimate only — I'll confirm the final scope and price before anything is booked.
If the options feel like too many choices, just tell me what the business does — I'll come back with a suggested feature list and price.
