Do you mean the "paid" numbers?
The "paid" total in the detailed report will only show the total amount paid against completed invoices, but not payments made against deleted, pending, or unfinished invoices.
The "paid" total on the payment report will show any payment made into the system for any invoice status.
So those numbers will not necessarily be the same.
If you have additional questions or if I'm misunderstanding your question, please email the relevant screen shots to support@dotnetinvoice.com.
