How we did it

  1. Step 1
    Protected Field Set

    8 specific human-editable fields are shielded from every automated sync.

  2. Step 2
    Placeholder Detection

    Treats placeholder values as empty so a real edit is never mistaken for a blank.

  3. Step 3
    Platform-Aware Merging

    Keeps leads from different source platforms from collapsing into one row.

  4. Step 4
    Proven Across Our Own Systems

    The only one of five sheet-CRM implementations that solves this cleanly.
