## Verdicts

**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.

**Zoho Books.** The public OpenAPI files cover 885 operations with OAuth scopes per module and operation, and the Free plan allows 1,000 API requests a day. No report endpoint, official SDK, SLA or dated API changelog was found, and the documented token calls put the client secret in the URL.

## Before you call either

### 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

### Zoho Books

1. Send `organization_id` as a query parameter on every call. Read it from `GET /organizations` first
2. Use the `api_domain` returned with the token, since each of the nine data centres has its own host (zohoapis.com, zohoapis.eu, zohoapis.in and others)
3. Send `Authorization: Zoho-oauthtoken <token>` and refresh hourly. Each user keeps at most 20 refresh tokens and the oldest is deleted
4. Stay under 100 requests a minute and the plan's daily cap. Codes 44, 45 and 1070 on a 429 mean minute, day and concurrency limits
5. To repeat an update safely, send `X-Unique-Identifier-Key`, `X-Unique-Identifier-Value` and `X-Upsert` with a unique custom field. Creates have no idempotency key
