Hi @Flyingkiwi,
Thank you for your reply, as well as for sharing an update on your situation. I'll point you in the right direction for support with your query.
At this point, I suggest you contact our Technical Support team for assistance. They can remotely access your computer, with your permission, and investigate these outstanding balances.
You can keep this article for reference: Contact QuickBooks Desktop support. It also has their hours of operation, so you know when they're available.
Open this article as well: AR balance on the Chart of Accounts does not match AR balance on reports. It has the steps you can take if you're in a situation where A/R amounts don't match.
Let me know in the comments below if you have other questions about your QBDT balances. I'll be around to help you out.
Thanks...
I ended up fixing these 6 and 10 year old transactions myself this afternoon.
For some reason, back then, QB allowed foreign currency deposits to be credited to Accounts Receivable in a different currency. (I am pretty sure that is now blocked). So the amounts credited to invoices was at a zero (1:1) rate, while the bank and financial side was correctly exchanged.
I 'fixed' it by changing the original transaction to credit a suspense account instead of A/R, then created a payment for the home currency debt from the suspense account, which zeroed out everything.
(All entries at original 2015 and 2011 dates to keep my auditor happy... I hope!)
Case closed.. but thought to leave the documentation in case someone else running multi currency has payments in multi currency to a single debt, and finds the open invoices report reading strange.
