# Integrations overview

> Connect accounting and payroll tools after the core time loop works.

Org admins connect integrations under **Settings → Integrations** (`/settings/integrations`) and **ADP Payroll** (`/settings/adp`).

| Integration    | Use it for                                    |
| -------------- | --------------------------------------------- |
| **QuickBooks** | Push or sync invoice/accounting data          |
| **Wave**       | Accounting sync for Wave-based firms          |
| **ADP**        | Payroll file numbers and ADP-related settings |

## Before you connect

1. Confirm [clients, projects, and team](/admin/invite-team) are in place.
2. Run one full loop: submit → approve → [invoice from WIP](/billing/invoice-from-wip).
3. Connect the integration with an account that has permission at the provider.

<Note>
  Exact field mapping and reconnect steps vary by provider. If a sync fails, disconnect/reconnect from Integrations and retry after fixing credentials at the provider.
