QuickBooks Desktop
Windows accounting, integrated through the Web Connector
QuickBooks Online
Cloud accounting with a REST API and webhooks
QuickBooks Desktop vs QuickBooks Online, side by side
| Dimension | QuickBooks Desktop | QuickBooks Online |
|---|---|---|
| Integration method | QuickBooks SDK and qbXML, through the Web Connector | REST API over HTTPS |
| Where it runs | A Windows app on the same machine or local network as QuickBooks | Intuit's cloud |
| Authentication | Registered with a .qwc file; your SOAP service implements the Web Connector WSDL | OAuth 2.0; access tokens last an hour, refresh tokens at most five years |
| Network | The Web Connector starts every connection, so no firewall ports open | Your app calls Intuit's API |
| Change notifications | Scheduled polling, no shorter than 1 minute, only while the Web Connector runs | Signed webhooks, plus change data capture for the last 30 days |
| Limits | Polling interval set by you and overridable by the user | 500 requests a minute per company; 10 a second per company and app |
| Test environment | Your own company file | Up to 10 sandbox companies, valid for two years |
| File imports | Excel or CSV for lists; IIF imports transactions but cannot export them | CSV, Google Sheets or Excel, under 1,000 rows per import |
| Product status | New US Pro Plus and Premier Plus subscriptions ended September 30, 2024; Enterprise unaffected | Sold and supported |
| Where it breaks for automation | Nothing syncs when the Windows machine or Web Connector is off, and the 64 bit SDK is not backward compatible | Data out calls are metered by partner tier, and webhooks can arrive late or out of order |
Where QuickBooks Desktop wins
QuickBooks Desktop wins on locality. The Web Connector starts every connection from inside your network, so nothing is exposed and no firewall ports open, and the company file never has to live in someone else's cloud. Enterprise is still sold, and the current qbXML 17.0 SDK is 64 bit and supports QuickBooks 2024 (R18 and later) and 2023 (R16 and later). For a business that wants the books on its own server, Desktop is still automatable.
- Businesses staying on QuickBooks Enterprise
- Books that must stay on your own network
- Batch syncs that can run on a schedule
- Teams with a Windows machine that stays on
Where QuickBooks Online wins
QuickBooks Online wins on everything an automation needs. OAuth 2.0 instead of a desktop app, webhooks signed with HMAC SHA256 and retried for hours, change data capture to catch anything a webhook missed, clear published limits, and up to 10 sandbox companies to test against. Data going in (Core calls) is unmetered under Intuit's App Partner Program, and the free Builder tier includes 500,000 data out calls a month.
- Real time syncs from cloud apps
- Event driven automation with webhooks
- Teams without an always on Windows machine
- New setups that want a supported product
The honest answer for automation
For a new automation project, QuickBooks Online is the easier and safer base: event driven, cloud to cloud, and actively sold. Choose Desktop only when you are staying on it anyway, usually Enterprise, and then design around the Web Connector: keep a Windows machine running, expect polling rather than events, and pin your SDK version. Desktop users are not stuck, but every automation has to pass through that one machine.
Lean QuickBooks Desktop
Lean QuickBooks Desktop if you are on Enterprise, want the books on your own network, and can keep a Windows machine running the Web Connector.
Lean QuickBooks Online
Lean QuickBooks Online if you want real time automation from cloud tools, with webhooks instead of polling.
QuickBooks Desktop vs QuickBooks Online: FAQ
- Does QuickBooks Desktop have an API?
- Not a cloud REST API. Intuit's route is the QuickBooks SDK and qbXML, usually through the QuickBooks Web Connector, a Windows app on the same machine or local network that calls your web service on a schedule.
- Does QuickBooks Online have webhooks?
- Yes. QuickBooks Online sends signed change notifications for connected companies. Intuit asks endpoints to respond within 3 seconds, retries failures for hours, and recommends a change data capture call to catch missed events, since events can arrive out of order.
- Can I still buy QuickBooks Desktop?
- In the US, new subscriptions to Pro Plus, Premier Plus, Mac Plus and Enhanced Payroll ended on September 30, 2024. Existing subscribers are not affected, and neither is QuickBooks Enterprise.
- Does the QuickBooks Online API cost money?
- Under Intuit's App Partner Program, data in (Core) calls are unmetered. Data out (CorePlus) calls are metered: the free Builder tier includes 500,000 a month, and paid tiers start at Silver, $300 a month for 1 million.
- What are the QuickBooks Online API limits?
- Intuit lists 500 requests a minute per company, 10 requests a second per company and app, 40 batch requests a minute, and at most 1,000 records per query response.
