Hello,
is there any report regarding sales invoice …how many Sales per day and how many pay amount against invoice or old amount and also showing old balance amount in one report
Date wise report
No, there is not a single report that includes all the things you mentioned. You should look at the Sales Invoices Totals by Item, Sales Invoices Totals by Customer, and Aged Receivables reports. You could also try to create a custom report. (Other users have posted their versions of similar reports on the forum.)
