Accounting¶

MDU implements PGC (Plano Geral de Contabilidade) double-entry bookkeeping integrated with Stripe webhooks.

Overview¶

All financial transactions flow through Stripe and are recorded as double-entry journal entries in the local database. The system supports automated VAT evidence collection and AIFSACCT-compatible export.

Tax Strategy¶

VAT: Included in all prices (tax-inclusive)
Stripe automatic_tax: Disabled
Declaration: Manual quarterly submission to accountant
Evidence: Billing address collected at checkout (billing_address_collection: required)

AIFSACCT Export¶

Stripe Custom Domain¶

billing.minidreamuniverse.com → CNAME hosted-checkout.stripecdn.com
This is a Stripe Custom Checkout Domain — never change to A record

Warning

The billing domain DNS must remain a CNAME to Stripe CDN. Changing it to an A record breaks checkout for all apps.
