Classify each field by necessity
Any field not required to create the account is flagged as a candidate to remove or postpone — this is the single biggest lever for reducing signup abandonment.

List every field on your signup form and get each one scored as essential, deferrable, or removable — so signup only asks for what's truly needed to create an account.

How it works
Score signup leanness
The ratio of required to total fields becomes your leanness score — fewer non-essential fields means a shorter, less intimidating first step.
Recommend where deferred fields belong
Non-essential fields aren't necessarily deleted — profile/company/role-type fields are recommended for a post-signup onboarding step instead of blocking account creation.
Frequently asked questions
Isn't collecting company/role info useful for sales?
Yes, but it doesn't need to happen before the account exists — collecting it during onboarding or a first-login step gets the same data without adding friction to the moment most likely to cause abandonment.
Should I ask for a password at all, or just use magic links?
Both are legitimate MVP choices — if you do use a password field, that's the only "security" field this tool assumes is required; email verification/2FA can be deferred separately.
How many fields should signup have?
As few as truly needed to create the account — for most B2B SaaS, that's just email and password (or email alone for a magic-link flow); everything else can typically move to onboarding.
How is this different from CheckoutSketch?
SignupTrim trims the account-creation flow specifically; CheckoutSketch trims the purchase/payment flow, which is a separate step even when the two happen close together.
