Turn work that would otherwise disappear into a record. HaulStamp is a simple tool for tracking waiting time and cargo-handling time as the work happens. When did the waiting begin? How long did cargo handling take? How many items were handled, and what was the weight per item? Details that feel obvious in the moment can become hard to remember later. HaulStamp keeps them together as one record you can return to. Review saved records anytime in History. If something needs correcting, you can edit it; the previous values, edit time, and reason for the change are kept in the record history. Set separate hourly rates for waiting and cargo handling to see a reference amount based on the time you recorded. Record quantity and weight per item to see the total weight. Export and share records as PDF, CSV, or plain text. Key features - Track waiting time - Track cargo-handling time - Record quantity and weight per item - See total weight - Set separate hourly rates for waiting and cargo handling - Calculate a reference amount from recorded time and hourly rates - Review past records - Edit records while keeping previous values, edit time, and reason - Export as PDF, CSV, or text - Switch among 55 interface languages HaulStamp is not a large management system. It is a small tool for keeping the work you did today in a form you can check again later. Reference amounts are estimates based on the hourly rates you set and the time you record. They do not represent an invoice amount, unpaid amount, or legally recognized amount. The initial release does not provide a way to delete saved records.
