can i merge multiple invoices into one? and if so how?

You can use the Statement feature instead of merging multiple invoices into one, as this is unavailable in QuickBooks, Tania-nassim.

Sending customer statements is a way to show all activity for a period (all invoices, credits, and payments) and ask for a single payment manually, without having to merge or change the original invoices.
