Implementation week versus five minutes — they are not the same product decision
Our table says SaudaFlow is live in five minutes and Sell.Do takes about a week, and read carelessly that looks like a straight win. It is not. Five minutes gets you a provisioned workspace with your projects loaded and your first lead landing. It does not migrate eleven years of enquiry history, reconcile four spreadsheets of channel-partner brokerage, or retrain sixty people who have muscle memory for another system.
For a firm of eight to sixty people with data mostly in spreadsheets and WhatsApp, five minutes is the honest number and the week would be overhead. For a developer with a legacy CRM, an agency in the loop and a booking process that has to keep working through the switch, the week is doing real work and skipping it would be reckless.
The practical test is what your data looks like today. If the answer is "a sheet, a group and everyone’s phone", speed helps you. If the answer is "a system of record with years in it", you want somebody planning the migration.
