Fast decision guide

Use this checklist when a firm is spending money on marketing but cannot explain which sources create qualified consultations, signed matters, and collected fees. The goal is not more reporting. The goal is deciding what to cut, what to fix, and what to scale.

Use software first if the firm lacks basic call tracking, CRM fields, or source capture.
Use a growth program first if the data exists but weekly accountability, intake scripts, follow-up, and budget decisions are inconsistent.
Do both when paid ads, referrals, and SEO are all active but no one owns source quality from first contact to signed matter.

Simple lead source ROI formula

Use the same formula across every source so the firm does not overvalue high-volume, low-quality channels.

Metric	Formula	Decision signal
Qualified lead rate	Qualified leads / total inquiries	Low rate means targeting or intake screening is weak.
Consultation show rate	Completed consultations / booked consultations	Low rate points to reminders, urgency, or lead quality problems.
Signed matter rate	Signed matters / completed consultations	Low rate suggests consult quality, pricing, fit, or follow-up problems.
Source ROI	(Collected fees – source cost) / source cost	Negative ROI means pause, repair, or narrow the source before adding budget.

Weekly accountability rhythm

Review this in a 30-minute weekly meeting. Pick one source, one bottleneck, one owner, and one follow-up date. Without that rhythm, even good tracking data becomes noise.

Review the top three sources by signed matters, not raw leads.
Find the largest drop-off: inquiry to qualified lead, qualified lead to consult, consult to signed matter, or signed matter to collected revenue.
Assign one experiment for the next seven days, such as a stronger callback script, faster first response, source-specific follow-up, or budget pause.
Record the result before changing more than one variable.

A law firm lead source ROI checklist helps small firms compare referrals, paid ads, SEO, directories, events, and repeat clients by actual signed matters instead of raw lead volume.

ROI fields to track

Field	Why it matters	Common mistake
Source	Identifies the channel or relationship that produced the lead.	Using “internet” for everything.
Qualified lead	Separates fit from noise.	Counting every call as equal.
Consultation	Shows whether intake can turn interest into appointments.	Ignoring no-shows.
Signed client	Connects marketing to actual case starts.	Optimizing only cost per lead.
Collected revenue	Shows the channel’s business value.	Stopping at signed retainers.
