WITHMIA v1.0.7 — Billing & Checkout, Complete

Note (July 2026): the Business and Enterprise plans are now called Team and Max. Prices are unchanged.

v1.0.6 perfected the login experience. v1.0.7 makes sure everything to do with payments works without a hitch: checkout, subscriptions, overage charges and extra seats.

The problem: a 500 error at checkout when the card was already on file

When someone tried to subscribe and their card was already registered with Flow.cl, the system failed with a 500 error. The worst part: Flow.cl had already charged the customer, but the system couldn’t send them to the success page.

Why it happened

The Flow.cl checkout flow has two steps:

1. createSubscription() — creates the subscription and charges automatically if the card is already on file
2. registerCustomer() — generates the payment URL so the customer can enter their card

The catch: when the card was already registered, createSubscription() charged successfully, but registerCustomer() threw an exception because the customer already existed in Flow.

The fix

registerCustomer() is now wrapped in a try/catch. If it fails (card already on file), the system assumes the payment went through and activates the subscription directly:

• It sets status = 'active' in the database
• It calculates ends_at based on the billing cycle (monthly or annual)
• It returns active to the frontend instead of a redirect URL
• The frontend picks that up and shows a success notification with an automatic redirect

Plan synchronisation with Flow.cl

We built the flow:sync-plans Artisan command, which syncs all 6 subscription plans (3 tiers × 2 cycles) straight to the Flow.cl API:

• Pro Monthly: $24.990 CLP
• Pro Annual: $254.990 CLP
• Business Monthly: $44.990 CLP
• Business Annual: $459.990 CLP
• Enterprise Monthly: $149.990 CLP
• Enterprise Annual: $1.529.990 CLP

No more creating plans by hand in the Flow dashboard.

A full audit of the billing system

We verified that every charging flow is correctly implemented and consistent with the pricing page:

Recurring subscriptions ✅

• The Flow.cl webhook confirms payments, renews ends_at and generates an Invoice
• Declined payments are handled (status → past_due or cancelled)

AI message overage ✅

• Tracking: AiUsage records messages used per company per month
• Limits: Free=500, Pro=2,000, Business=8,000, Enterprise=25,000
• Price: $5.990 CLP per additional 1,000 messages
• Cap: 5,000 extra messages per period, maximum
• Automatic charging: the ChargeOverageBilling command runs monthly
• Alerts: warning emails at 90% and 100% of the limit

Extra seats ✅

• Price: $10.500 CLP/month or $107.100 CLP/year per extra member
• One-off payment via Flow.cl or dLocal when inviting from the dashboard
• The webhook creates the invitation, sends the email and increments max_agents

AI models by plan ✅

• Free: GPT-4o-mini (basic)
• Pro: GPT-4o-mini + GPT-4o
• Business: GPT-4o + Claude
• Enterprise: all of them + fine-tuning
• Automatic smart routing by plan via getRecommendedModel()

Add-on pricing corrected

We fixed the copy in the team panel that still showed “$9.990/month” (the old price) — it now correctly reads “$10.500/month” and “$107.100/year”, in line with Flow.cl and the landing page.

Consistency verified across the board

The three sources of truth are perfectly in sync:

Source	Status
config/billing.php (backend)	✅ Correct
SubscriptionPage.tsx (app)	✅ Correct
Pricing.tsx (landing page)	✅ Correct
Flow.cl dashboard	✅ Correct
