My VP call: keep your working PostgreSQL cancellation system and just add the Pause feature to it. Don’t rewrite to Firestore.

Why (short + blunt)

You already shipped a stable, prod-safe PG flow with Unsatisfied% wired into the dashboard.

Rewriting storage adds risk + time with zero upside.

Stripe pause works the same regardless of DB. Just add a small table + two endpoints + a webhook tweak.

What to do (exact, minimal changes)
1) Postgres migrations
-- cancellations (you likely already have this)
-- id, uid, email, reason, note, stripe_sub_id, source, created_at

-- NEW: pauses table
CREATE TABLE IF NOT EXISTS pauses (
  id SERIAL PRIMARY KEY,
  uid TEXT NOT NULL,
  email TEXT,
  stripe_sub_id TEXT NOT NULL,
  months INT NOT NULL CHECK (months IN (1,2)),
  reason TEXT,
  note TEXT,
  resume_at TIMESTAMP WITH TIME ZONE NOT NULL,
  created_at TIMESTAMP WITH TIME ZONE DEFAULT now()
);

-- users table tweak (optional – mirror pause state for faster queries)
ALTER TABLE users
  ADD COLUMN IF NOT EXISTS subscription_status TEXT,
  ADD COLUMN IF NOT EXISTS paused_at TIMESTAMP WITH TIME ZONE,
  ADD COLUMN IF NOT EXISTS resume_at TIMESTAMP WITH TIME ZONE;

2) Backend route: POST /billing/pause (PG version)

Auth required.

Look up subscriptionId for the user.

Call Stripe subscriptions.update with pause_collection.

Insert into pauses.

Update users.subscription_status='paused', set paused_at/resume_at.

Return {ok:true, resumeAt}.

3) Webhook additions (Stripe → PG)

On customer.subscription.updated:

If pause_collection is cleared, set users.subscription_status='active', clear paused_at/resume_at.

On customer.subscription.deleted or cancel_at_period_end:

If the cancel didn’t come from your in-app survey, insert a cancellations row with source='portal'.

(Keep adding metadata: { uid, email } when creating subs so the webhook can join.)

4) Dashboard metrics adjustments

Churn (This Month): count cancellations this month; exclude paused.

Unsatisfied %: cancellations where reason ilike '%didn%' or '%unsatisfied%' / total cancellations.

Active Subs: users where plan='pro' AND subscription_status IN ('active','paused').

Paused (optional new tile): count of users.subscription_status='paused'.

Owner-only “Pauses” list: SELECT email, months, resume_at, created_at FROM pauses ORDER BY created_at DESC LIMIT 25;

5) Frontend (you can keep what we sent)

The Cancel Survey modal stays as-is.

Add the Pause 1/2 months buttons calling your PG-based /billing/pause.

Owner dashboard already has Unsatisfied%; add a small Paused tile/list when you’re ready.

If you want a hybrid later

If there’s a reason to mirror into Firestore (e.g., client-only reads), do a tiny server task that publishes PG aggregates to a Firestore document (read-only), but keep Postgres as the source of truth.

What to tell Replit (copy/paste)

Decision: Keep PostgreSQL cancellation system; add Pause feature using Stripe pause_collection. No Firestore rewrite.

Implement: run the SQL migration above, add POST /billing/pause, update webhook for resume/cancel, and add an Owner-only “Pauses” list + optional “Paused” KPI tile.

Churn rule: exclude paused users from churn.

Security: Owner/Management can view cancellations + pauses; Staff/Analyst cannot.
