Key features of this saas subscription signup form template
Everything you need to launch this form in minutes, share it with your team, and collect submissions reliably.
Plan picker that fits any tier structure
Radio fields with descriptive labels (Starter / Pro / Business / Enterprise) let users see what they get before they commit. Pair with monthly/annual toggle to surface the discount.
Conditional fields for self-serve vs. sales-assist
Show "Number of seats" only when team size is 10+. Hide payment fields when the user picks Enterprise and route them to a sales call instead.
CRM-ready field labels
Field names match HubSpot and Salesforce defaults out of the box — no mapping headaches when you wire up the integration.
Promo code field with validation
A simple text field your billing system can check at checkout. Strips whitespace, uppercases input, and won't block submission if invalid.
Mobile-optimized in one column
No multi-column layouts that break on phones. 60% of B2B trial signups now happen on mobile — this form respects that.
Built-in consent capture
Terms and Privacy Policy checkbox is recorded with a timestamp on every submission, giving your legal team the audit trail they need.

Ways to use this template
Pricing page primary CTA
Replace your "Start Free Trial" button with a link to this form. Pricing-page visitors who click already have intent — keep the form short, capture plan and email, and pass everything else to onboarding.
Sales-assisted trial signup
Send the link from a sales email after a demo. Pre-fill known fields via URL parameters so the prospect only sees the new questions, and let your AE jump in if the team-size field crosses 50.
Partner or reseller signup
Add a "Partner code" field and route those submissions to a separate Slack channel for your partnerships team. Different plan options can be shown via conditional logic based on the partner type.
Product-led growth onboarding
Drop the form inside your product after a user hits a paywall. The "use case" field lets you personalize the next-step email and route to the right CSM based on company size.
Migration from a competitor
Add a "current tool" dropdown and a file upload for their export. Marketing offers a white-glove import for users coming from specific competitors — this is where they self-identify.
Annual plan upgrade campaign
Send existing monthly customers a link with the billing-cycle field pre-set to annual. The discount math is shown inline, and submissions feed straight into your billing system via webhook.
Workflow integrations
Connect this form to your existing tools with no middleware. Every submission triggers your workflow automatically.
Real-time sync
Data appears in your CRM or spreadsheet within 1–2 seconds of submission — no cron jobs, no delays.
Conditional routing
Route submissions to different Slack channels, HubSpot pipelines, or Airtable bases based on field values.
Two-way data flow
Pre-fill form fields with CRM data for returning visitors. Update existing records instead of creating duplicates.
Why choose Flexform?
Frequently asked questions
Does this form handle actual payment processing?
No — this form captures signup intent and customer details, then hands off to your billing provider (Stripe, Chargebee, Paddle) via the Webhook integration. Most SaaS teams prefer this split because it keeps PCI scope out of the form layer and lets you change billing providers without rebuilding the signup flow.
Can I customize the plan options to match my pricing tiers?
Yes. Open the form in FlexForm, click the plan field, and replace the options with whatever your tiers are called. Or use the AI editor — type "change the plans to Hobby, Studio, and Agency" and it rewrites the field for you in a second or two.
How do I route new signups to my sales team in real time?
Connect the form to Slack and a new message lands in your chosen channel within seconds of submission, with the company name, plan, and team size in the message body. For higher-intent signups (Enterprise plan, team size 50+), set up a conditional Slack notification to a separate channel so AEs see them first.
Will this work for an annual-only or usage-based pricing model?
It will. Hide the billing-cycle field if you only sell annual, or replace it with a "Monthly usage estimate" dropdown for usage-based pricing. The AI editor handles both changes from a single prompt.
Can I embed this signup form inside my mobile app?
Yes. The FlexForm Kotlin Multiplatform SDK lets you embed any form inside an Android or iOS app with a single integration. The form respects your app theme, works offline-then-sync, and submissions hit the same integrations as the web version.
What happens if someone abandons the form halfway through?
You can turn on partial saving in the form settings, and incomplete submissions are written to the form_sessions table as drafts. Your marketing team can then trigger an abandoned-signup email via the Webhook integration to your ESP — typically recovers 10-15% of drop-offs.
Is the free plan enough to run real signup traffic?
For most early-stage SaaS, yes. The free plan covers unlimited submissions and the core integrations. You only need to upgrade if you want custom branding removed, advanced conditional logic, or higher API rate limits for the webhook integration.
Does it capture UTM parameters for attribution?
Yes. UTM tags in the form URL are captured automatically on every submission and passed through to HubSpot, Google Sheets, or your webhook payload. No extra setup — they appear as hidden fields in the submission record.
