The best form software for a small business site is not one product but the one whose free tier does the site's job and whose paid tier is priced for one site rather than an agency. Ranked on that criterion, three WordPress plugins from the public directory come out ahead for the jobs a small site actually has, a contact form, a quote form with conditional logic and a payment form, and the ranking below says why each, with the vendor's own listing linked so the free and paid lines can be read rather than trusted. It then does what no software listing does: works the form out first, on the free sheets on this site, so the software is chosen to fit a form whose charge, entries and fields are already known.
Best form software: the ranking, and the criterion
Ranked on one criterion, whether the free version does a small site's job and what the paid version adds, read from each plugin's own directory listing. No figure from any listing is repeated here; the listings are linked.
- WPForms Lite: the free version builds a contact form in minutes with a drag-and-drop editor and stores entries; conditional logic and payment fields are on the paid side, so a site that needs a quote or payment form is pricing the licence
- Contact Form 7: free throughout for the contact form, placed with a shortcode, with no entry storage and no logic built in; the right answer for a site that needs one form and reads its email
- Formidable Forms: the free version stores entries and handles calculations, which makes it the free tier closest to a quote or order form; conditional logic and payments are on the paid side
The criterion: the free tier and the job
A contact form with six fields is every plugin's free tier, so for that job the ranking is about entry storage and the shortcode. A quote form needs conditional logic and a payment form needs a payment field, and those are the two features most often behind the licence, so for those jobs the ranking is about the paid tier's price for one site. Read each listing for those two lines before the name; the ranking above is that reading on the day this page was written, and the listings will move.
Work the form out before the software
On the payment form calculator a form charging $243.56 has the processor keeping $7.36 and $236.20 reaching the account, so a builder that takes a share of each payment is priced against $7.36, not against a monthly fee. On the contact form design sheet a page with 1,200 visitors produces 36 entries a month, which is the figure to size a free tier's entry cap against. On the request a quote form sheet a four-service form shows 8 of 17 fields, which is what the conditional logic has to do.
What form software does not do, and the register
None of the three works the form out beforehand, and each keeps the entries in its own table while the licence is paid. Shortcodo Pro is the register: every form with its logic and shortcode, every entry with its status and payment, whichever plugin rendered the form, at a flat $9 a month. The plugin builds the form on the page; the register is where the form's design and its entries live, and the sheets are where the form is worked out first.
Questions people ask about best form software
Why are only WordPress plugins ranked?
Because the site owner this page is for runs a WordPress site, and the public directory is where the free and paid lines can be read by anyone. Hosted builders are compared by category in the plugin guide.
Is the ranking paid for?
No. Nothing on this site is an advertisement and no vendor pays a commission; the criterion is stated and the listings are linked so the reading can be checked.
Does Shortcodo replace the plugin?
It works the form out first and keeps the entries as a register. The form on the page can be any of the three; the register does not care which.
