Job stripe-nextjs-supabase-subscriptions · revised 9 October 2026
Add monthly and yearly Stripe plans to a Next.js app
One test account can buy, renew and cancel the agreed plan; Supabase reflects the correct current access state without duplicate subscriptions.
You might be seeing
- Users cannot choose and pay for an existing plan
- The database cannot decide whether a member should retain access after a renewal or cancellation
No passwords, keys, card details or admin invites needed to start.
What usually happened
An existing Next.js/Supabase app has login but no verified Stripe subscription lifecycle, so charging a customer and granting, renewing or removing plan access cannot be handled safely.
Who it’s for: Owner of an existing Next.js and Supabase service that already has accounts but no paid plans.
Usually starts when: The owner has named Pro and Team plans but cannot charge or enforce their monthly and annual subscriptions.
The result: One test account can buy, renew and cancel the agreed plan; Supabase reflects the correct current access state without duplicate subscriptions.

Checks you can run yourself
Compare test-mode price IDs
In Stripe test mode, list the four monthly/yearly prices and map each to its access rule.
Look for: If any price or rule is missing, do that before discussing a fixed build.
What you get
- Reviewed Next.js route and Supabase migration/permission changes
- Four-price checkout matrix, renewal/cancellation, Billing Portal and access-control test evidence
Included
- Wire two named plans with monthly and yearly prices through hosted Stripe Checkout
- Handle paid, failed, renewed and cancelled states in a test-mode webhook; expose Stripe Billing Portal
Not included
- Custom card-number collection or Stripe Connect payouts
- Tax advice or VAT settings
- Migrating old subscriber records
- A new login system or additional plan catalogue
How we know it’s done
Agreed with you before work starts. Each check produces evidence you keep.
A successful test-mode Checkout activates the purchased plan on one account and a replay creates no second subscription row
Evidence: Stripe test event ID and redacted Supabase plan row
A failed renewal or cancellation removes or changes access according to the owner-approved rule, not merely the browser redirect
Evidence: Test event log and before/after account access screens
Each of the four test price IDs (two plans, monthly and yearly) opens Checkout and grants only its agreed plan to the matching disposable account.
Evidence: Four-row matrix of price ID, subscription ID, plan and observed protected-page access.
A successful simulated renewal preserves access; Billing Portal shows the correct account subscription and cancellation changes access at the owner-agreed effective date.
Evidence: Stripe test-clock/event results, portal walkthrough and access checks before and after cancellation.
Invalid webhook signatures are rejected; replayed and stale test events do not regress entitlement; a different signed-in user cannot read or change another subscription.
Evidence: Negative-test log, Supabase row-policy checks and duplicate/stale event results.
Sign-off. You inspect the named test result and sign off before payment. Your authorised account holder performs and verifies any live change.
If it fails. If the agreed test fails, you do not pay for this fixed scope. We hand over the findings and agree whether to stop or re-quote; no surprise work.
When it fits, and when we stop
It fits when
- The app already has working login and a Supabase user identifier
- The owner can create the four Stripe prices in test mode and authorise plan rules
We stop and tell you if
- The app has no stable user identifier to attach to Stripe customers
- The buyer needs marketplace payouts, legal tax configuration or an unsupported bespoke checkout
What could go wrong
Keep the previous code or configuration on a named test copy. The handover lists every change and its reverse; live database changes or external effects require a separate owner-approved plan.
Scroll the table sideways to read it all.
| Risk | How we handle it |
|---|---|
| Wrong plan unlocked or cancelled | Use price IDs and owner-approved access mapping, then review all four lifecycle cases. |
| Stale or duplicated webhook events corrupt status | Store event IDs and compare current Stripe subscription status before applying access changes. |
An independent reviewer checks the specific data, payment and permission risks, the redacted test result and whether the owner can safely reverse the change.
How we deliver
We arrange the work and independent review, then show you the result against the agreed checks. You keep authority over your systems.
- Map each test price to the app user and plan record
- Implement hosted Checkout, Billing Portal and verified, idempotent webhook updates
- Test paid, failed, renewal and cancellation events; independently review access control
- Hand over the reviewed change, evidence and reversal steps; the owner controls the live switch.
This is a one-off job, not emergency cover or a subscription. We confirm eligibility, the total price, a start window and a delivery date before you accept. Work starts only after agreed inputs, secure access, any licences and necessary permissions are in place. Hosting, platform and supplier charges are excluded unless the written quote includes them. No charge or booking is created by an enquiry.
Need to keep it working?
After implementation, discuss maintaining test-mode subscription lifecycle and access-control checks as plans or code change.
Ongoing work is separately scoped and quoted: no monitoring, response-time guarantee or automatic subscription is included in this job.

What you can check
This is a new service. We have not delivered this job for a client yet.
Other ways to get this done
- Ask the original platform or app vendor whether its support can fix this under your existing plan.
- If someone already maintains this system for you, ask them to test this exact failure on a copy first.
Questions
Can a success page alone unlock my plan?
No. The verified Stripe event updates the account; the success page is only a message.
Who creates my live Stripe prices?
You control your account. We hand over the tested mapping and you approve the live switch.
Start with an email
Send us
- Plan names, proposed monthly/annual amounts and intended access per plan
- Redacted auth and database schema sketch, without keys
Later, once you agree
- Test-mode plan IDs and a disposable account through owner-controlled secret settings
- Read-only code handoff and test database with dummy users
- A company-controlled secure handoff agreed before access: no live passwords, keys, private code or customer records by ordinary email.
You keep the live service, account, production keys and customer records. Agents work only on an authorised copy with synthetic data and a company-controlled handoff; a person owns Synthetic Industry and remains accountable. Your authorised account holder approves and carries out the live change.
