Domestic accounts

I take it to mean the accounts in the country where the business belongs (i.e. the opposite of foreign accounts). But I could well be wrong.

'Domestic accounts' is not a standard expression. Domestic means belonging to the home country. As to domestic accounts, it depends on the context of the question.

A question I did basically said that candidates although asked to explain managing receivables by domestic accounts some explained factoring and invoice discounting.... so I was just wandering whether it was a term used for standard in house management ie. For managing receivables -Producing statements, credit checking customers, issuing final demands etc ..... so it is not a standard term?

It simply means managing receivables in their own country (as opposed to how to manage receivables for sales to foreign countries)
