Checkout Usability
Part of Checkout conversion and usability
Finding unnecessary fields in a checkout form
Audit checkout inputs by order journey, find fields with no necessary purpose and make conditional requests easier to understand.
List every input a buyer sees, then ask what the store cannot complete correctly without its value for that order. Remove fields with no necessary checkout purpose. Show a field only on the journeys that need it when the checkout supports that rule. Keep genuinely required details and explain less obvious requests.
Inventory the form by journey
Record fields as they appear to a new guest buyer, if guest checkout is offered. Repeat for returning buyers and materially different order types. Delivery, click and collect and digital fulfilment can require different information. Include visible choices as well as text boxes: an optional company name or open billing-address section still asks for attention.
For each field, note its label, required or optional status, when it appears and which process uses its value. Include fields supplied by apps or payment components in the visual inventory. Check any proposed change to those components against the actual platform and provider integration.
| Question for each field | Decision it informs |
|---|---|
| What order task uses this value? | Keep it if that task cannot work correctly without it. |
| Does every journey need it? | Show it only for relevant products or fulfilment choices where possible. |
| Has the buyer already supplied it? | Reuse it where accurate and appropriate. |
| Is it optional but prominent? | Mark it optional and consider a less intrusive presentation. |
| What happens when it is blank or wrong? | Explain the error and offer a way to correct it. |
Checkout field requirements by order journey (Australia)
- Delivery (standard)
- Click and collect
- Digital download
- Business purchase (ABN required)
Challenge the field, not the customer
A delivery address has an obvious role when goods are shipped. A collection order calls for a separate check of what information pickup actually needs. A phone number may support a particular delivery or contact process; if it is required, explain why. Do not keep a field mandatory merely because the current form requires it.
Check whether the form asks for the same address twice without a reason or splits a value into inputs buyers struggle to use. A billing address cannot simply be discarded when a payment or business process requires it. The aim is an accurate rule for each journey, not the smallest field count.
Make the remaining fields easier to complete
Give controls clear, persistent labels. Mark both required and optional fields so buyers need not infer which they can skip.
Place brief instructions beside unusual requests. If validation finds an error, identify the affected field and explain how to fix it in text. Preserve other correct entries where safe.
For Australian orders, include an address with a unit number when checking the form. If the store accepts overseas orders, review those address formats separately. These are proposed checks, not results for a particular checkout.
Steps to simplify checkout forms in Australia
- Label all fields clearly and consistently
- Mark required and optional fields explicitly
- Provide brief instructions for unusual requests
- Validate errors with clear feedback
- Test address formats including unit numbers
Decide what to change
Assign each field an outcome: keep, make conditional, make optional, combine or remove. Record the reason and the process that uses it.
Check affected order types through fulfilment and payment before release so removing an input does not break a later task. After release, review validation errors and customer contacts alongside completion; a shorter form can shift work to support.

- What order task uses this value?
- Does every journey need it?
- Has the buyer already supplied it?
- Is it optional but prominent?
- What happens when it is blank or wrong?
