When `submit_batch` sent `amount` as a JSON number, the server responded `{\"status\": \"accepted\"}` \u2014 masking the problem \u2014 but silently reconciled it as `0.0`, so `server_totals()[\"batch\"]` stayed at `0.0` while the test expected `25.00`.\n\nI confirmed this by probing the opaque service directly:\n- `amount` as number `19.99` \u2192 accepted, but totals stayed `0.0`\n- `amount` as string `\"19.99\"` \u2192 accepted, totals correctly became `25.0`\n- Wrong top-level keys (`items`, `batch`) \u2192 `\"bad request\"`; `records` is required\n\n## Fix\n\nIn `billing/client.py`, `submit_batch` now serializes each amount as a string:\n\n```python\npayload = {\"records\": [{\"id\": r[\"id\"], \"amount\": str(r[\"amount\"])} for r in records]}\n```\n\n## Verification\n\n`pytest tests/test_billing.py` \u2192 **1 passed**.
