From PhpCOIN Documentation
phpCOIN v1 does not support "Statements" in the traditional sense, but it can be faked in an "all or nothing" deal for a specified customer:
will display a list of transactions (invoices and payments) for customer xxxxx.
The listing may be in separate "Credits" and "Debits" sections, so [Admin] -> [Parameters] -> [layout] -> [invoices] -> [Invoice Transaction Listing: Enable Split Listing] -> [NO] will display the output in a single section arranged in transaction date-order.
Once the listing is on-screen, a [print] button is available, which will normally print the current module output without the site header/columns/footer
