The challenge. Solar energy.
In a solar energy group it is common to have one company per plant or project, each with its own CNPJ and its own bank accounts. Every month finance repeats the same routine for each company: log into the bank, download the statement, post fees and yields, identify transfers between the group's companies and put together the supporting documents for the audit.
