Выражение встречается в следующем контексте:

In- and out payments receipts should be avoided as far as possible. The aim should be that the only kind of in- and out payments receipts is the safe difference adjustments. All other transactions of money into or out from the safe should be made in other ways.

а "into or out from the safe" ?.. - вне безопасных ... (сделок?)

Expense due to representation
Invoice - **The question is for free**, in many cases the restaurants accept to send an invoice after the restaurant visit.
If invoicing is no option, the expense will be transferred to the bank account of the employee with use of a specific form, Out payment receipt, Appendix 1. The employees need to be informed that it will take up to a week to have the money at the bank account in time. The handling for this should be added to the “expense routine” for the country.

подразумевается "вопрос открыт" или "неоднозначен" ?
