I am new to QB, only ever used Sage, can you post more than 1 payment to any single CIS invoice? On Sage you cannot. Cant find anything here anywhere to explain!

Hi christine-bulbec, thanks for joining the Community - you can record multiple payments against the CIS invoice by selecting 'Make payment' (on the bill) > on the following bill payment screen, enter the payment details and then edit the amount in the 'bill payment' box. You can then select save & new to record another payment, or save & close to record this at a later date. The total amount owing on the open bill will be reduced by the payment applied. You'll also see a pro-rata CIS deduction (less CIS) on the CIS return (Taxes > CIS). You can check out this CIS guide for more help and see how to run CIS reports for further insight. 🙂

Hi @christine-bulbec 

You should be able to post any number of payments against a Bill > via Bill Payments or (from the Invoice itself > Make Payment).

Similarly, Receive Payments to post against Invoices.

The CIS-ness of the Bill/Invoice shouldn't matter. 

However, exactly how QBO will treat for CIS purposes, I'm not sure - I have CIS activated in QBO but do not use it for CIS submissions.  QBO doesn't (unless it's been fixed) deal correctly with CIS Supplier Credits.

Your best bet is to try applying multiple payments - check whether it affects the CIS Return as you'd expect, if not post a follow up & see if a workaround can be found.

Hope this helps.
