B2C home-services platform

Key decisions

1. 1. Business logic in the database, thin apps

   Pricing, discounts, order states and money are computed in PostgreSQL functions, and row-level security policies enforce access. Users hit the database under their own role; the secret key exists only on the server. Result: one source of truth for money, whichever app sends the request.

2. 2. Outbox for the outside world

   Notifications and Telegram messages are written to an outbox in the same transaction as the order change and delivered by a separate service. Nothing gets lost, and nothing is sent about an action that didn't happen.

3. 3. Payments behind a switch

   bePaid handles immediate charges or an authorization hold until work starts, refunds, chargebacks, webhooks and reconciliation. The payment mode is an owner-controlled switch, with no release needed. Extra work is billed only after the customer approves it in their account.

4. 4. Data and access

   SMS one-time codes for customers and specialists, password + TOTP for staff. Addresses and personal data are stored encrypted in a separate schema. Every operator action on money or data requires 2FA and lands in the audit log.

5. 5. Remote quality control

   Specialists follow a checklist, take before/after photos and mark stages (arrived, started, finished) with geolocation and timestamps. Operators accept the result or send it back.

6. 6. Pricing rules as a product decision

   Fixed published price, +10% at peak times, total discount capped at 20%, bonus points cover up to 15% of an order. Discounts come out of the platform's share; the specialist's share stays intact.
