I prepared an invoice, so why do my client’s margin and bonus/loss not take it into account?

Invoice preparation creates invoices to be validated, which are not yet posted to the sales journal and are not yet taken into account in profitability analysis reports. The corresponding direct debits are not yet created either.
They do not yet have a number: they are only drafts marked with a "Draft" watermark.
They cannot yet be transferred to accounting.
Deleting them automatically removes the "Invoiced" indication next to the budgets, time or expenses that may have been used as the basis for their preparation, allowing automatic preparation again in case of error.

Once invoices to be validated have been reviewed by the person responsible for validation, they can be transferred to the sales journal. They then receive their number, can be sent to clients and exported to accounting, and are included in revenue and the various reports.
