How does ProFlow360 help you document a Massachusetts tenancy?

ProFlow360 records and organizes inspection evidence; it does not tell you what the statute requires or allows. What it records, for any state:

  • Move-in, routine, pre-move-out and move-out inspections with photos timestamped at capture.
  • Each move-out photo beside its move-in match, filed under the tenancy.
  • Itemized lines with your classification, the amount you entered, and the estimate or invoice attached.
  • An issued record that is sealed, shared by a link that expires and can be revoked.

Do this in ProFlow360

Keep the photos, the call and the invoice on the same line

Every deduction line carries the move-in and move-out photos, your classification and its documents, so the record can be followed by someone who was not there.
