Specify integrations early
Integrations are the most common cause of timeline slippage, because they depend on third parties you don't control — their API quality, their approval process, their availability. Listing them during scoping rather than mid-build materially reduces risk. See How long does a custom development project take?.
For each one, establish: which direction data flows, whether the vendor's API supports it, whether you already hold an account, and what happens when that service is unavailable.
On the standard platform, these integrations already exist — see Can the platform integrate with third-party systems?.
