A laundry with home pickup does not take an order the same way a shop with counter collection does. Checkout is now a sequence of steps you arrange, so the form matches your operation instead of the other way round.
Arrange the Steps You Need
Services, address, date and time, contact details, special instructions and payment are separate steps. Include the ones that apply, drop the ones that do not, and set the order.
Booking and Delivery Options
Pickup and delivery windows are configured behind the schedule step, so customers only choose from slots you can actually service.
Customers Can Move Back and Forth
Each step keeps its own place in the browser address bar, so a customer can go back to fix an address without losing everything they have already entered.
