Assemble the RR support workpaper as one PDF. Drop the whole invoice-and-check folder under the first tab, add the Bank Statements under the second, then generate the final report. The tool reads the file names: a check ends in “- check” or “- check EFT”, so each invoice is followed by its own check, pairs run in the order of the leading number, and the Bank Statements close the report. Either tab may hold any number of files or none. Everything runs in your browser; nothing is uploaded, so file size is limited only by your machine.
