Attachment Bundler by Atesen Software helps bookkeepers export a selected set of QuickBooks Online attachments. Filter supported transactions by date, type, vendor or customer, account and amount, then preview matching files before downloading ZIP parts with readable filenames and CSV/Excel indexes. QuickBooks Online already provides bulk ZIP downloads; Bundler adds transaction filtering and organised indexing. Unlimited previews and the first 25 files per company are free. It reads QuickBooks Online without changing records. QuickBooks Desktop is not supported, and this is not a full backup service.
