The purchase form is worth designing on the basis of the information needed for implementation. Readable fields and understandable messages help to move from the selected product to the correct order.
Explain every question
With each field, save the data to which the data will be used. Some information is needed for delivery, some for the sales document, and others can only be auxiliary. Separate these goals instead of transferring all the fields available in the system to the form.
Do not treat each group of customers identically. If the company purchases require a different set of data, show it in the appropriate context. The final scope is agreed with those responsible for the implementation and requirements of the store.
Show error where it was created
The general “form contains errors” does not help to improve the order. Show the field and explain the expected format with a understandable language. Keep the information entered correctly so that the customer does not have to repeat all the work.
For example, the error in the postal code should lead to the correction of this field, rather than clearing the address and selecting delivery. Also check that the message does not disappear before the recipient can read it.
Prepare a rehearsal on the phone
Take the actual order scenario, but use the safe test data. Go through it without the help of the designer. Note the labels, the visibility of the next step and the behavior after opening the screen keyboard.
The sample shall include:
- transition between fields;
- correcting an incorrect alert;
- change the type of data to the document;
- return to the previous stage;
- re-check the summary;
- a clear confirmation of receipt of the contract.
Do not add targets in the last step
The loyalty program, newsletter and additional recommendations may take place, but should not obscure the main activity. In the project set their priority and way of conscious choice. For the store serving Warsaw, also check the difference between delivery data and reception in the item. Related materials describe basket and confirmations after purchase.
