The timelines
A production B2B website takes 4 to 6 weeks from signature to go-live. An AI agent system takes 5 to 8 weeks. A full platform takes 8 to 16 weeks. A Diagnostic Sprint takes 2 weeks and produces the specification the others are built from.
What causes delays
Product data, almost every time. A catalogue build needs your products in some structured form, and the gap between "we have a price list" and "we have clean product data" is usually two weeks of extraction and correction. The Santosh catalogue was assembled from nine separate price-list PDFs.
After that: waiting on brand assets, waiting on decisions from someone who was not in the kickoff, and scope added mid-build. The last one is handled by fixed scope and a written change process rather than goodwill.
How to make it fast
Send whatever product data exists on day one, however messy. Name one decision-maker who can approve without a committee. Book the weekly review call as a recurring slot rather than scheduling it each week. Those three things account for most of the difference between a four-week build and a nine-week one.
