What 86Hours does
Everything you need to keep an unpaid-invoice case moving.
From the first calculation to a reviewable Evidence Pack, 86Hours keeps the facts, communication and next task connected. Every capability below reflects the available product and its stated limits.
One connected recovery record
Give every unpaid invoice its own workspace
Recovery Pack customers can keep one saved case; Pro customers can manage multiple cases for one business. Payment is handled by Stripe and card details are not stored by 86Hours.
See every action in date order
Record communications, notes and current case events in date order. The timeline is an administrative record; it does not validate the underlying statement.
Keep evidence attached to the story
Each accepted customer upload receives a permanent exhibit reference, is linked to the matching timeline entry and stays selected for the full Evidence Pack. File-security checks remain automatic and fail closed.
Export a complete, reviewable record
Generate a chronology and Evidence Register whose exhibit references match the timeline. Each verified safe static copy is attached; the exact original stays private with its integrity hash and provenance. The export is not court-approved or independently authenticated.
Send an approved, branded payment email
Pro and Bookkeeper customers can send through a supported connected Gmail or Microsoft account where configured. You approve each message, it comes from your connected business address, and 86Hours adds its brand and website automatically. Automatic outbound recovery messages remain disabled.
