Building a Subscription Business on Bubble.io: The Complete Model
Recurring revenue is the most valuable model in software. Complete subscription data architecture, the trial-to-paid conversion flow that maximises upgrades, plan limit enforcement with code, and why framing limits as growth moments converts better than error messages.
Why Recurring Revenue Changes Everything
A subscription business — where customers pay monthly or annually for ongoing access — is the most valuable business model in software. It creates predictable revenue, reduces customer acquisition pressure, and compounds over time as retention improves. Building the subscription model correctly in Bubble.io requires deliberate architecture across your data model, Stripe integration, plan limits, and renewal flows. This guide covers the complete pattern.
What You Need in Your Data Model
Workspace
subscription_status
option set: Trialing / Active / Past_Due / Cancelled / Paused
plan
-> Plan data type
stripe_customer_id
text (created on workspace creation)
stripe_sub_id
text (set by checkout.completed webhook)
trial_ends_at
date (trial expiry)
current_period_end
date (next billing date)
seats_used
number (denormalised member count)
mrr
number (monthly revenue from this workspace)
// Plan data type
Plan
name
text (Starter / Growth / Scale)
stripe_price_mo
text (Stripe Price ID for monthly billing)
stripe_price_yr
text (Stripe Price ID for annual billing)
seat_limit
number (0 = unlimited)
record_limit
number (0 = unlimited)
trial_days
number (14 or 30)
is_active
yes/no (can new workspaces subscribe to this plan?)
The Most Important Customer Journey
Workspace created: start trial automatically
On workspace creation, set subscription_status = Trialing and trial_ends_at = today + Plan’s trial_days. Schedule a backend workflow to fire 3 days before trial_ends_at with a conversion prompt email. Schedule another to fire on the trial end day.
Trial ending email: 3 days before expiry
Send a personalised email showing what the workspace has accomplished in the trial (records created, team members, feature usage). Remind them what happens when the trial ends. Include a single upgrade button linking to your Stripe Checkout session.
Trial end: grace period, not hard cutoff
When trial_ends_at passes without conversion, do not immediately block access. Set subscription_status = Trial_Expired and show an upgrade banner inside the app. Give a 3-7 day grace period where they can still use the app but see persistent upgrade prompts. Hard cutoffs on trial end cause panic and churn; soft landings with urgency convert better.
Post-conversion: onboard paying customers differently
When checkout.completed fires and subscription_status becomes Active, trigger a different email sequence. Paying customers should receive a confirmation, a getting-started guide relevant to their plan tier, and an offer of a 1:1 onboarding call from the founder for the first 30 days.
How to Technically Restrict Features by Plan
// Check record count against plan limit before creating
Step 1 Only when
: Workspace’s record_count < Workspace's plan's record_limit
OR Workspace’s plan’s record_limit = 0
// If condition fails: show upgrade modal instead of creating
// Upgrade modal text: make it a growth moment, not an error
// ‘You’ve created [count] projects! Upgrade to Growth for unlimited.’
// NOT: ‘Error: you have reached your project limit.’
// Seat limit check (before inviting a new member)
Step 1 Only when
: Workspace’s seats_used < Workspace's plan's seat_limit
OR Workspace’s plan’s seat_limit = 0
Frame Limits as Growth Moments, Not Errors
When a customer hits a plan limit, the way you frame it determines whether they feel frustrated or motivated. ‘You have reached your 5 project limit’ produces frustration. ‘You have created 5 projects — you are growing fast! Upgrade to Growth for unlimited projects’ produces motivation to upgrade. The data is the same. The framing is everything.
