Can Nassima forecast my revenue?

Yes. You'll find it under Marketing, not Reports — go to Marketing, then Forecasts, pick a metric, and generate the projection.

Nassima builds the forecast from your own business history, not a template or an industry average. 30 metrics are supported, spanning finance, operations, marketing, and HR, including:

Revenue, tracked daily, weekly, and monthly Demand-related metrics, such as inventory reorder demand, stock consumption, and service demand by category Staffing, including staff workload and technician capacity

For demand forecasting specifically, including planning around your busier and quieter periods, see Demand forecasting.

Each metric needs a minimum run of history before Nassima will forecast it: 30 data points for a daily metric, 12 for a weekly one, 6 for a monthly one. Below that, Nassima reports that there isn't enough data yet rather than generating a number anyway.

Forecasts are available on the Growth plan and above.

The point is planning: staffing, inventory, and budgets built on your own numbers instead of a guess.
