Estimates only. Preset numbers are typical ranges for small operators, last reviewed 2026-09-15 — your own CRM or invoicing data beats every preset, so replace them. The follow-up lift and speed-to-lead drop are assumptions you can change, not measurements of your business. Not financial or legal advice.
