Italian to English Bus/Financial Accounting

Talking about disputes (quantities of goods, invoice totals etc.) arising between companies in the same group who buy and sell from/to each other. I think I know what they mean here (they've got to get the thing sorted and the two sets of books have to tally, right?), but I can't find an accounting term for "correspondenza".

"Definita la controversia nei modi e nei tempi suindicati, le parti, se necessario, dovranno porre in essere le opportune scritture di rettifica al fine di garantire la corrispondenza contabile delle rispettive posizioni".
