+## 2. Stripe Billing & Checkout
+
+### Plans & Pricing
+
+| Plan | Monthly | Annual (25% off) | Unit Limit |
+|------|---------|-------------------|------------|
+| Starter | $29/mo | $261/yr ($21.75/mo) | 50 units |
+| Professional | $79/mo | $711/yr ($59.25/mo) | 200 units |
+| Enterprise | Custom | Custom | Unlimited |
+
+### Stripe Products & Prices
+
+Each plan has **two Stripe Prices** (monthly and annual):
+
+| Env Variable | Description |
+|-------------|-------------|
+| `STRIPE_STARTER_MONTHLY_PRICE_ID` | Starter monthly recurring price |
+| `STRIPE_STARTER_ANNUAL_PRICE_ID` | Starter annual recurring price |
+| `STRIPE_PROFESSIONAL_MONTHLY_PRICE_ID` | Professional monthly recurring price |
+| `STRIPE_PROFESSIONAL_ANNUAL_PRICE_ID` | Professional annual recurring price |
+| `STRIPE_ENTERPRISE_MONTHLY_PRICE_ID` | Enterprise monthly recurring price |
+| `STRIPE_ENTERPRISE_ANNUAL_PRICE_ID` | Enterprise annual recurring price |
+
+Backward compatibility: `STRIPE_STARTER_PRICE_ID` (old single var) maps to monthly if the new `_MONTHLY_` var is not set.
+
+### Two Billing Paths
+
+| Path | Audience | Payment | Trial |
+|------|----------|---------|-------|
+| **Path A: Self-serve (Card)** | Starter & Professional | Automatic card charge | 14-day no-card trial |
+| **Path B: Invoice / ACH** | Enterprise (admin-set) | Invoice with Net-30 terms | Admin configures |
+
+### Webhook Events Handled
+
+| Event | Action |
+|-------|--------|
+| `checkout.session.completed` | Triggers full provisioning pipeline (card-required flow) |
+| `invoice.payment_succeeded` | Sets org status to `active` (reactivation after trial/past_due) |
+| `invoice.payment_failed` | Sets org to `past_due`, sends payment-failed email |
+| `customer.subscription.deleted` | Sets org status to `archived` |
+| `customer.subscription.trial_will_end` | Sends trial-ending reminder email (3 days before) |
+| `customer.subscription.updated` | Syncs plan, interval, status, and collection_method to DB |
+
+All webhook events are deduplicated via the `shared.stripe_events` table (idempotency by Stripe event ID).
+
+---
+
+## 3. 14-Day Free Trial
+
+### How It Works
+
+1. User visits `/pricing`, selects a plan and billing frequency
+2. User enters email + business name (required)
+3. Clicks "Start Free Trial"
+4. Backend creates Stripe customer (no payment method)
+5. Backend creates subscription with `trial_period_days: 14`
+6. Backend provisions org with `status = 'trial'` immediately
+7. User receives activation email, sets password, starts using the app
+
+### Trial Configuration
+
+| Setting | Description |
+|---------|-------------|
+| `REQUIRE_PAYMENT_METHOD_FOR_TRIAL` | `false` (default): no-card trial. `true`: uses Stripe Checkout (card required upfront). |
+
+### Trial Lifecycle
+
+| Day | Event |
+|-----|-------|
+| 0 | Trial starts, full access granted |
+| 11 | `customer.subscription.trial_will_end` webhook fires |
+| 11 | Trial-ending email sent ("Your trial ends in 3 days") |
+| 14 | Trial ends |
+| 14 | If card on file: Stripe charges, subscription becomes `active` |
+| 14 | If no card: subscription cancelled, org set to `archived` |
+
+### Trial Behavior by Plan Frequency
+
+- **Monthly trial**: Trial ends, charge monthly price
+- **Annual trial**: Trial ends, charge full annual amount
+
+### Trial End Behavior
+
+Configured in Stripe subscription: `trial_settings.end_behavior.missing_payment_method: 'cancel'`
+
+When trial ends without a payment method, the subscription is cancelled and the org is archived. Users can resubscribe at any time.
+
+---
+
+## 4. Monthly / Annual Billing
+
+### Pricing Page Toggle
+
+The pricing page (`PricingPage.tsx`) features a segmented control toggle:
+- **Monthly**: Shows monthly prices ($29/mo, $79/mo)
+- **Annual (Save 25%)**: Shows effective monthly rate + annual total ($21.75/mo billed annually at $261/yr)
+
+The selected billing frequency is passed to the backend when starting a trial or creating a checkout session.
+
+### Annual Discount
+
+Annual pricing = Monthly price x 12 x 0.75 (25% discount):
+- Starter: $29 x 12 x 0.75 = **$261/yr**
+- Professional: $79 x 12 x 0.75 = **$711/yr**
+
+---
+
+## 5. Provisioning Pipeline
+
+When a trial starts or `checkout.session.completed` fires, the backend runs **inline provisioning**:
+
+1. **Create organization** in `shared.organizations` with:
+   - `name` = business name from signup
+   - `schema_name` = `tenant_{random_12_chars}`
+   - `status` = `trial` (for trial) or `active` (for card checkout)
+   - `plan_level` = selected plan
+   - `billing_interval` = `month` or `year`
+   - `stripe_customer_id` + `stripe_subscription_id`
+   - `trial_ends_at` (if trial)
+   - Uses `ON CONFLICT (stripe_customer_id)` for idempotency
+
+2. **Create tenant schema** via `TenantSchemaService.createTenantSchema()`
+3. **Create or find user** in `shared.users` by email
+4. **Create membership** in `shared.user_organizations` (role: `president`)
+5. **Generate invite token** (JWT, 72-hour expiry)
+6. **Send activation email** with link to set password
+7. **Initialize onboarding** progress row
+
+### Provisioning Status Polling
+
+`GET /api/billing/status?session_id=xxx` (no auth required)
+
+Accepts both Stripe checkout session IDs and subscription IDs. Returns: `{ status }` where status is:
+- `not_configured` -- Stripe not set up
+- `pending` -- no customer ID yet
+- `provisioning` -- org exists but not ready
+- `active` -- ready (includes `trial` status)
+
+---
+
+## 6. Account Activation (Magic Link)
+
+### Validate Token
+
+`GET /api/auth/activate?token=xxx` -- returns `{ valid, email, orgName, orgId, userId }`
+
+### Activate Account
+
+`POST /api/auth/activate` -- body `{ token, password, fullName }` -- sets password, issues session
+
+---
+
+## 7. Guided Onboarding Checklist
+
+| Step Key | UI Label | Description |
+|----------|----------|-------------|
+| `profile` | Profile | Set up user profile |
+| `workspace` | Workspace | Configure organization settings |
+| `invite_member` | Invite Member | Invite at least one team member |
+| `first_workflow` | First Account | Create the first chart-of-accounts entry |
+
+---
+
+## 8. Subscription Management & Upgrade/Downgrade
+
+### Stripe Customer Portal
+
+Users manage their subscription through the **Stripe Customer Portal**, accessed via:
+- Settings page > Billing card > "Manage Billing" button
+- Calls `POST /api/billing/portal` which creates a portal session and returns the URL
+
+### What Users Can Do in the Portal
+
+- **Switch plans**: Change between Starter and Professional
+- **Switch billing frequency**: Monthly to Annual (and vice versa)
+- **Update payment method**: Add/change credit card
+- **Cancel subscription**: Cancels at end of current period
+- **View invoices**: See billing history
+
+### Upgrade/Downgrade Behavior
+
+| Change | Behavior |
+|--------|----------|
+| Monthly to Annual | Immediate. Prorate remaining monthly time, start annual cycle now. |
+| Annual to Monthly | Scheduled at end of current annual period. |
+| Starter to Professional | Immediate. Prorate price difference. |
+| Professional to Starter | Scheduled at end of current period. |
+
+Stripe handles proration automatically when configured with `proration_behavior: 'create_prorations'`.
+
+### Subscription Info Endpoint
+
+`GET /api/billing/subscription` (auth required) returns:
+```json
+{
+  "plan": "professional",
+  "planName": "Professional",
+  "billingInterval": "month",
+  "status": "active",
+  "collectionMethod": "charge_automatically",
+  "trialEndsAt": null,
+  "currentPeriodEnd": "2026-04-18T00:00:00.000Z",
+  "cancelAtPeriodEnd": false
+}
+```
+
+---
+
+## 9. ACH / Invoice Billing
+
+### Overview
+
+For enterprise customers who need to pay via ACH bank transfer or wire, an admin can switch the subscription's collection method from automatic card charge to invoice billing.
+
+### How It Works
+
+1. **Admin** calls `PUT /api/admin/organizations/:id/billing` with:
+   ```json
+   { "collectionMethod": "send_invoice", "daysUntilDue": 30 }
+   ```
+2. Stripe subscription is updated: `collection_method = 'send_invoice'`, `days_until_due = 30`
+3. At each billing cycle, Stripe generates an invoice and emails it to the customer
+4. Customer pays via ACH / wire / bank transfer
+5. When payment is received, Stripe marks invoice paid and org remains active
+
+### Access Rules for Invoice Customers
+
+| Stage | Access |
+|-------|--------|
+| Trial | Full |
+| Invoice issued | Full |
+| Due date passed | Read-only (past_due) |
+| 15+ days overdue | Admin may archive |
+
+### Switching Back
+
+To switch back to automatic card billing:
+```json
+{ "collectionMethod": "charge_automatically" }
+```
+
+---
+
+## 10. Access Control & Grace Periods
+
+### Organization Status Access Rules
+
+| Status | Access | Description |
+|--------|--------|-------------|
+| `trial` | **Full** | 14-day trial, all features available |
+| `active` | **Full** | Paid subscription, all features available |
+| `past_due` | **Read-only** | Payment failed or invoice overdue. Users can view data but cannot create/edit/delete. |
+| `suspended` | **Blocked** | Admin suspended. 403 on all org-scoped endpoints. |
+| `archived` | **Blocked** | Subscription cancelled. 403 on all org-scoped endpoints. Data preserved. |
+
+### Implementation
+
+- **Tenant Middleware** (`tenant.middleware.ts`): Blocks `suspended` and `archived` with 403. Sets `req.orgPastDue = true` for `past_due`.
+- **WriteAccessGuard** (`write-access.guard.ts`): Blocks POST/PUT/PATCH/DELETE for `past_due` orgs with message: "Your subscription is past due. Please update your payment method."
+
+---
+
+## 11. Authentication & Sessions

+### Token Architecture
+
+| Token | Type | Lifetime | Storage |
+|-------|------|----------|---------|
+| Access token | JWT | 1 hour | Frontend Zustand store |

+## 16. Manual Intervention & Ops Tasks
+
+### Stripe Dashboard Setup
+
+1. **Create Products and Prices** for each plan:
+   - Starter: monthly ($29/mo recurring) + annual ($261/yr recurring)
+   - Professional: monthly ($79/mo recurring) + annual ($711/yr recurring)
+   - Enterprise: monthly + annual (custom pricing)
+   - Copy all Price IDs to env vars
+
+2. **Configure Stripe Webhook** endpoint:
+   - URL: `https://yourdomain.com/api/webhooks/stripe`
+   - Events: `checkout.session.completed`, `invoice.payment_succeeded`, `invoice.payment_failed`, `customer.subscription.deleted`, `customer.subscription.trial_will_end`, `customer.subscription.updated`
+
+3. **Configure Stripe Customer Portal**:
+   - Enable plan switching (allow switching between monthly and annual prices)
+   - Enable payment method updates
+   - Enable cancellation
+   - Enable invoice history
+
+4. **Set production secrets**: `INVITE_TOKEN_SECRET`, `JWT_SECRET`, `WEBAUTHN_RP_ID`, `WEBAUTHN_RP_ORIGIN`
+
+5. **Configure SSO providers** (optional)
+
+### Ongoing Ops
+
+- **Refresh token cleanup**: Schedule `RefreshTokenService.cleanupExpired()` periodically
+- **Monitor `shared.email_log`**: Check for failed email deliveries
+- **ACH/Invoice customers**: Admin sets up via `PUT /api/admin/organizations/:id/billing`
+
+### Finding activation URLs (dev/testing)
+
+```sql
+SELECT to_email, metadata->>'activationUrl' AS url, sent_at
+FROM shared.email_log
+WHERE template = 'activation'
+ORDER BY sent_at DESC
+LIMIT 10;
+```
+
+---
