Can I batch action closed transactions and assign missing "property"?

You can only edit transactions individually, kevintwells.

You'll have the option to invite an accountant to reclassify the transactions by batch. Let me guide you on how:

1. Go to Settings and select Manage users.
2. Select the Accounting firms tab.
3. Select Invite.
4. Enter your accountant's info and select Save.

Your accountant will receive an email with a link for signing in to your company. Accountants have the advantage to undo reconciliations, reclassify, and write off invoices.
