# System Services

> Foundational capabilities your app needs — auth, payments, notifications, file storage, audit logs, and multi-language support.

System Services covers the foundational capabilities every modern app needs but most teams shouldn't have to build from scratch. Archie pre-selects the services your app needs based on the plan; you tune the configuration here.

## Available services

The catalog includes:

* **User Management** — authentication methods, role-based access, onboarding flows. Configure email/password, Google, Microsoft, Facebook, Apple sign-in. Toggle a guided onboarding wizard for new users.
* **Notifications** — in-app, email, and SMS channels. Pick which channels to enable per notification category.
* **File Storage** — managed file storage for images, videos, and documents. Used by the [Assets](/docs/features/assets/overview) surface.
* **Payment Processing** — payment types (one-time, subscriptions, usage-based, invoices) and methods (cards, ACH, digital wallets, manual). Drives the Stripe integration.
* **Audit Logs** — record system events. Levels: Basic (security events), Standard (security + business actions), Advanced (full traceability — coming soon).
* **Multi-Language Support** — internationalization for the generated frontend.

## What this drives

Each service influences:

* **Backend infrastructure** — auth providers and token handling, file-storage buckets, notification channels, audit-log tables
* **Integrations** — turning on Payment Processing pulls Stripe into the integration set; turning on SMS pulls Twilio
* **Frontend flows** — sign-in screens, onboarding wizards, notification preference panels
* **Data model** — `users`, `roles`, `audit_logs`, and similar shared tables come from these services

## Editing

Toggle services on or off, change configuration (e.g. enable Apple Sign-In, change audit-log level), and Archie re-generates the relevant parts of the code on the next generation pass. You don't need to re-run the plan.

## FAQ

<AccordionGroup>
  <Accordion title="What's the difference between a system service and an integration?">
    A system service is a capability (Notifications, Payments). An integration is the third-party provider that powers it (Twilio, Stripe). Turning on a service usually adds the corresponding integration to the project — you can swap the integration but not skip having one if the service is enabled.
  </Accordion>

  <Accordion title="Can I add my own custom service?">
    Not as a first-class system service today. Custom capabilities live in [Custom Functions](/docs/features/backend/custom-functions/overview) and your data model. The system-services catalog is the curated list of cross-app capabilities Archie maintains.
  </Accordion>

  <Accordion title="Why is Advanced audit logging marked as coming soon?">
    Advanced (compliance-ready) audit logging — full traceability of every data change — is in development. Basic and Standard levels work today and cover most use cases.
  </Accordion>

  <Accordion title="Do enabled services cost extra?">
    The services themselves are part of the platform. Their underlying integrations have provider costs (Stripe transaction fees, SendGrid email volume, Twilio per-message charges) — those are billed by the provider, not by Archie.
