The real cost in practice
The displayed entry price is almost never the real price for daily users. With a tool like Sierra, two classic traps blow the budget: quotas that run out fast and add-ons billed separately.
Joute rule of thumb: for daily professional use, budget 1.5 to 2x the displayed price. For Sierra that would put the real monthly bill around ?-? €/month over time.
