No guarantee. This is an estimate of potential based on stated assumptions — not a forecast and not a promise. Your results depend on your market, your team and how you use ROIS.

Assumptions (not facts)

These ranges are our working assumptions for small and mid-sized businesses. They are not measured for your business — if you know better numbers, the estimate changes with them.

  • 30–50% of missed callers wanted to buy or book (the rest are suppliers, existing customers or wrong numbers).
  • 25–40% of those reply to a text sent within a minute of the missed call.
  • Answering new enquiries within minutes instead of hours lifts your conversion rate by 5–15% (relative: 20% becomes about 21–23%).
  • 30–50% of quotes get no structured follow-up today.
  • 5–12% of those are won with a timely, structured follow-up.
  • 5–15% of ad spend sits in campaigns that don't pay back and can be cut or moved.
  • Extra gross profit = extra revenue × your gross margin + the marketing saving.
