## 原文

# SmartBill Invoicing

Use `scripts/smartbill_cli.py` for deterministic SmartBill API calls instead of ad-hoc HTTP snippets.

## Workflow

1. Collect invoice input from the user.
2. Validate payload locally before sending:
   - `python scripts/smartbill_cli.py validate-payload --input references/invoice-example.json --show-payload`
3. Dry-run to inspect the normalized payload without calling the API:
   - `python scripts/smartbill_cli.py create-invoice --input <invoice.json> --dry-run`
4. Issue final invoice after explicit user confirmation:
   - `python scripts/smartbill_cli.py create-invoice --input <invoice.json> --allow-final`
5. Retrieve PDF once series and number are known:
   - `python scripts/smartbill_cli.py download-invoice-pdf --series-name <SERIES> --number <NO> --output <file.pdf>`

## Required Environment

Set these before calling SmartBill:

- `SMARTBILL_USERNAME` - SmartBill login email
- `SMARTBILL_TOKEN` - SmartBill API token
- `SMARTBILL_COMPANY_VAT_CODE` - default CIF (optional but recommended)

Optional overrides:

- `SMARTBILL_API_BASE` (default: `https://ws.smartbill.ro/SBORO/api`)
- `SMARTBILL_TIMEOUT_SECONDS` (default: `30`)
- `SMARTBILL_RETRIES` (default: `2`)

## Command Guide

- `validate-payload`
  - Parse and normalize payload shape (bare invoice object or `{ "invoice": {...} }` wrapper both accepted).
  - Validate minimum required structure before API calls.
- `create-invoice`
  - Create invoice via `POST /invoice`.
  - Requires `--allow-final` to issue a final invoice.
  - Supports `--dry-run` (prints normalized payload, no API call) and `--force-draft`.
- `get-series`
  - Query available SmartBill series via `GET /series`.
- `download-invoice-pdf`
  - Fetch PDF via `GET /invoice/pdf` using CIF + series + number.

## Payload Format

The invoice payload is a flat JSON object sent directly to the SmartBill API. See `references/invoice-example.json` for the canonical minimal example and `references/smartbill-api.md` for field documentation.

Both formats are accepted as input to the CLI:
- Bare invoice object: `{ "companyVatCode": "...", "client": {...}, ... }`
- Wrapped: `{ "invoice": { "companyVatCode": "...", "client": {...}, ... } }`

The CLI unwraps automatically and sends the invoice object directly to the API.

## Operational Rules

- Always use `--dry-run` first to confirm the normalized payload before hitting the API.
- Treat final invoice issuance (`isDraft: false`) as a high-impact action requiring explicit user confirmation.
- Set `client.saveToDb: false` and `products[].saveToDb: false` to avoid persisting test data.
- Preserve SmartBill response data (series, number, message) in run logs.
- Respect SmartBill rate limits: max 30 calls per 10 seconds.

## References

- Read `references/smartbill-api.md` for payload field reference, endpoint mapping, and auth/rate-limit notes.
- Use `references/invoice-example.json` as the canonical starting payload template.
