Short answer
Excel and WhatsApp are enough while there is one source of truth and low volume. Switch to a system when information duplicates, roles collide, and the owner rebuilds status by hand.
What Excel and WhatsApp do well
- Instant start.
- Total flexibility.
- Almost zero license cost.
- The team already knows them.
What they cannot hold
- Three copies of the same schedule.
- Field notes that never return to the office.
- Costs and stock rebuilt after the fact.
- An owner acting as the human glue of the process.
Five-minute test
- Can you state an order's status without asking on chat?
- Is there one place with the current price?
- Can a new hire understand the flow without a week of shadowing?
- Can the field update the system without calling the office?
If the answer is no on two or more, it is no longer a discipline problem: it is a system problem.
How to switch without stopping the company
Digitize one bottleneck. Ship a usable phase. Only then connect the store or ads. That is the Bazan method: diagnosis, written scope, visible phases.
FAQ
Can I stay on Sheets with automation?
Sometimes. Lightweight Google Workspace tools fix small pains. When roles and complex statuses appear, an app fits better.
How much is the jump?
It depends on scope. Diagnosis at no cost; written budget if there is a fit.
