The idea is the following.
Have products and services that pass through different states (order,
committed, reviewed, approved, slope, bill, invoice), these may belong to a
period or many (period = months).
The filter may include the client query or not.
La idea es la siguiente.
Tengo productos y servicio que pasan por distintos estados (pedido,
comprometido,revisado, aprovado, pendiente, a facturar, facturado), estos
pueden pertenecer a un periodo o a muchos (periodo=meses).
El filtro del query puede incluir el cliente o no.

Hard to say without seeing an actual query ...
Is the state field the only one used to filter the result set?
