Paperhawk — Bill reader for Windows

(01) The problem

Every month, a stack of utility bills had to be typed into spreadsheets, one unit at a time.

(02) The idea

Point it at a folder. It reads every bill, finds the right row and fills it in, then saves a new copy and leaves the original alone.

(03) What I built

Inside it.

  1. 01

    Reads PDFs

    Invoice number, account and amount go into the right row.

  2. 02

    Reads scans too

    Windows’ built-in text recognition handles paper bills that were scanned.

  3. 03

    Knows the bill type

    It looks at the first file and sets itself up.

  4. 04

    Checks the numbers

    Flags any bill that looks very different from last month.

  5. 05

    Private by design

    Nothing leaves the office PC. No cloud, no account.

(05) Result

Hours of typing turned into one click.
