## Which one, for what

### Odoo External API (C)

Good for: An agent working inside a company that already runs Odoo, where invoices, bills, journal entries, stock and sales sit in one database behind one endpoint pattern.

Ahead on:
- Schema & documentation, 51 against 43
- Security & auth, 61 against 38
- Transparency & trust, 93 against 49

Also in its favour:
- Open source

Watch for: On Odoo Online the external API is limited to the Custom plan. One App Free and Standard exclude it

### QuickBooks Online API + MCP (D)

Good for: An agent working a US small business's books, where QuickBooks is the default ledger.

Ahead on:
- Payments & pricing, 30 against 22
- Maintenance & community, 85 against 73

Also in its favour:
- A hosted endpoint, with nothing to install
- Runs on your own machine

Watch for: Rate limits, developer terms, partner tiers and deprecation rules are behind a JavaScript portal that returns nothing to a plain fetch

## Verdicts

**Odoo External API.** One endpoint pattern reaches every model, with field selection, filters and paging, and keys that expire within three months. On Odoo Online the external API needs the Custom plan, there is no OpenAPI file, and the acceptable use policy asks for about one call a second with no parallel calls.

**QuickBooks Online API + MCP.** Official MCP server from Intuit with 145 tools and flags to remove write, update or delete tools. Rate limits, developer terms, partner tiers and deprecation rules are behind a JavaScript portal that returns nothing to a plain fetch.

## Before you call either

### Odoo External API

1. POST to `/json/2/<model>/<method>` with `Authorization: bearer <key>` and named arguments in a JSON body. Add `X-Odoo-Database` when one host serves several databases
2. Pass `fields` and `limit` on `search_read`. The default limit is every matching record
3. Create invoices and bills on `account.move` with `move_type` set to `out_invoice` or `in_invoice`, then call `action_post`. A new move is a draft
4. Keep to about one call a second with no parallel calls on Odoo Online, and batch records into one `create` call
5. Ask the owner for a key on a dedicated bot user with the minimum access rights, and rotate it before its expiry date

### QuickBooks Online API + MCP

1. Store the realmId with the tokens. Every URL needs it and the token alone doesn't name the company
2. Persist the new refresh token from every refresh response. The previous one expires 24 hours later
3. Use the query endpoint with MAXRESULTS and STARTPOSITION for reads rather than fetching by id
4. Send a unique `requestid` query parameter on writes, so a retry returns the first response instead of posting twice
5. On 429, wait for Retry-After before retrying, and don't retry other 4xx errors
