Reduce form friction on the way to purchase
Every field you ask for before purchase is a chance for the shopper to give up.
In short
- The average checkout carries ~3 fields it doesn't need: 11.3 asked vs. 8 required (Baymard).
- A 'Continue as guest' button instead of a register wall was worth +45% sales / ~$300M a year in the classic case study.
- Autofill isn't a nice-to-have: Shopify guest checkouts with autofill convert 45% higher than those without.
Shoppers stall on fiddly form fields on the way to pay.
Fix applied
Fewer fields, smarter inputs, mobile-friendly layout.
Illustrative. Measured on your traffic first.
Most checkouts ask for about three fields they don't actually need. Baymard puts the average flow at 11.3 fields when 8 would close the sale. Every extra one is a moment where a tired thumb on a phone decides this isn't worth it. The shopper already wants to buy; the form is the thing standing between intent and revenue.
What's the problem?
Forms and inputs on the way to purchase, like gift notes, account creation prompts, and address fields, create drop-off, especially on mobile.
Why does this happen?
- Optional fields are presented as required or unavoidable.
- Account creation is forced before checkout.
- Mobile keyboards and fiddly inputs frustrate shoppers.
- The order total only resolves at the final step. When tax, shipping, or a surcharge appears for the first time after the address form, the shopper has already invested effort and then gets a surprise number, which read…
- Address fields are split into too many pieces. Separate inputs for street, apartment, city, state, ZIP, and country each demand a tap, a keyboard switch, and a decision. On a phone, this is where people quietly close th…
- Autofill silently fails. If your form uses non-standard field names or custom widgets, the browser can't recognize them, so the shopper hand-types everything they normally never type, friction that's invisible to you i…
- Error handling punishes the shopper after the fact. Validation that only fires on submit, wipes the form, or rejects a phone format without explaining why turns one typo into a reason to leave.
What does the research show?
Independent researchFigures below are from independent studies, not StorePilot data. They're why this problem is worth testing on your own store.
-
The average ecommerce checkout has 11.3 form fields but only needs about 8 to complete a purchase: roughly 3 unnecessary fields per checkout.
Baymard Institute ↗ -
When a major retailer replaced a forced 'Register' step with a 'Continue' button and optional guest checkout, sales rose 45%, about $300 million in the first year (the '$300 Million Button').
User Interface Engineering / Jared Spool (Center Centre) ↗ -
Being required to create an account drives 19% of intended-purchase checkout abandonments, tying it with credit-card trust as a top reason.
Baymard Institute (Checkout Usability study) ↗ -
In Shopify testing, guest checkouts that used autofill converted 45% higher than guest checkouts without it; across sites, autofill cut checkout abandonment 75% and form-completion time 35%.
Shopify, via Google (Chrome blog) ↗ -
Across 20.1 million checkout sessions only 54.4% complete, and completion is worse on mobile (51.4%) than desktop (56.9%): the mobile friction gap is real.

How does StorePilot AI fix it?
- StorePilot detects abandonment around input-heavy steps on the path to purchase.
- It tests reducing or deferring non-essential fields on the cart and pre-checkout surfaces.
- It measures completion to confirm fewer fields means more buyers.
How do you fix it, step by step?
-
Count your fields and cut to the bone
List every input on the path to payment and mark each as required-to-fulfill or nice-to-have. Anything in the second bucket (gift notes, 'how did you hear about us', second phone, company name) comes off the main path or moves to optional, aiming for the ~8 that actually ship the order.
-
Make guest checkout the default route
Lead with a 'Continue' or 'Continue as guest' button, not a register/login wall. If you want accounts, offer one-click creation after the order is placed, when you can pre-fill it from the details they just typed.
-
Fix autofill so the browser does the typing
Use standard HTML autocomplete attributes (e.g. given-name, family-name, postal-code, address-line1) and standard input types so Chrome and Safari recognize the fields. Test a real autofill on a phone. If it doesn't populate the whole address in one tap, your field naming is the blocker.
-
Collapse the address into fewer taps
Default the country, combine fields where you can, and add address autocomplete so one selection fills street, city, and ZIP. Set correct keyboard types (numeric for ZIP and card number, email keyboard for email) so shoppers aren't fighting the wrong layout.
-
Show the real total before the form, not after
Surface shipping cost (or a clear estimate) and any fees before the shopper invests in typing. The total appearing as a surprise at the end is its own abandonment trigger, separate from the fields themselves.
-
Validate inline and keep what they typed
Check each field as they leave it, write error messages that say exactly what to fix, and never wipe the form on a failed submit. One rejected phone format shouldn't cost you the order.
An illustrative example
Demo data- What StorePilot detects
- Shoppers stall at a pre-checkout step that nudges account creation, then abandon.
- The fix it builds & tests
- Defer account creation to post-purchase and make non-essential fields clearly optional.
- The projected outcome
- Example projection: more shoppers reaching checkout. (Illustrative demo figure.)
Key takeaways
- The average checkout carries ~3 fields it doesn't need: 11.3 asked vs. 8 required (Baymard).
- A 'Continue as guest' button instead of a register wall was worth +45% sales / ~$300M a year in the classic case study.
- Autofill isn't a nice-to-have: Shopify guest checkouts with autofill convert 45% higher than those without.
- Only 54.4% of checkouts complete, and mobile (51.4%) lags desktop (56.9%), so test the cut on a phone, not your laptop.
