QuietSignal
Invoice software

Invoice automation for small business that checks, not just files.

The problem

Automation that only files the PDF still leaves the checking to you. The invoice is in a folder, the total is in a spreadsheet, and whether the lines add up to that total is still your job.

How QuietSignal handles it

  • Connects to the Gmail inbox your vendors already send to; nothing changes for them.
  • Reads each new invoice attachment line by line as it arrives.
  • Multiplies each line out and checks the sum against the printed total.
  • Matches the same invoice sent twice before it is paid again.
  • Holds anything that does not add up, with the reason in plain words.

Common questions

What does the automation actually do?
It reads, checks and files. Every invoice is read as data, the math is checked, duplicates are matched, and what does not add up is held for you.
Do I need to change how my vendors send invoices?
No. Connect the inbox they already send to. You can also forward or upload.
What is not automated?
The decision. Anything that does not add up waits for you with the reason stated.
