Hi @Kaz24
Ignore everything in the previous reply - it's bot-rendered gibberish!
Do you use QBO to send weekly/monthly invoices to your Contractor & they pay on these invoices?
Or do you use Bank Account matching & Sales Receipts to log things into QBO?
If Invoices/Payment, you will have sent them an invoice as usual & they've overpaid. Don't worry too much about CIS at this stage (QBO doesn't deal with it correctly anyway).
Use Receive Payment to enter the payment at full amount but only select last month's invoice - QBO will clear that & leave the overpayment as a credit on their account.
Next month, use Receive Payment to enter the (under)payment & use the remaining credit to clear the invoice in full.
I don't use Bank Matching / Sales Receipts but let me know & I'll rethink the above.
Now for the CIS bit:
Caveat ... I don't actually use QBO to file CIS so this may be a bit vague (as above, Intuit/QBO have no idea how it works & no apparent interest in getting it right so I steer clear).
QBO accounts for CIS on invoices sent not on payments received (which is wrong), so the CIS on the overpayment will be carried over to next month. This is fine - as long as you can show what's happened is genuine, not even HMRC will get in too much of a tizz over it.
(it might be a bit more complicated if you're off-setting CIS Suffered against PAYE or Corporation Tax & the two month's straddle the end/start of the tax year / your financial year)
Hope this helps.
