What Does a PI Firm's Marketing Budget Look Like at Different Revenue Levels?

PI firms at different revenue levels don't just spend different amounts on marketing — they spend it differently. The channel mix shifts, the vendor relationships become more complex, and the reporting requirements change substantially. Understanding what typical marketing budgets look like at your revenue level can help you calibrate your own spending and identify where you might be over- or under-invested.

The following breakdowns are based on patterns we see across PI firms, not prescriptive formulas. Use them as reference points, not targets. Every market, case mix, and firm culture is different.

Firms at $2M Annual Revenue

At $2 million in annual gross revenue — roughly $167,000 per month — most PI firms are investing between $15,000 and $40,000 per monthon lead generation. That's typically 9–24% of gross revenue, with the higher end being more common for younger firms that haven't yet built strong referral pipelines.

Typical Channel Mix

At this revenue level, most firms are concentrated in one or two primary channels. A common configuration:

• Google Ads or LSA: 50–70% of marketing budget
• One or two lead vendors: 20–40%
• Referral/organic (minimal direct cost): 10–20% of case volume

Social advertising is often tested but rarely accounts for a major share of the budget at this stage. Firms are learning which channels work in their market before diversifying.

Key Characteristics

The managing partner is often still involved in marketing decisions — or making them entirely. Attribution is usually manual: a spreadsheet updated monthly, if at all. Cost per case is known approximately but not precisely by vendor. Intake is typically one to three people, sometimes with heavy attorney involvement in consultations.

Firms at $5M Annual Revenue

At $5 million annually — about $417,000 per month — lead generation spend typically ranges from $50,000 to $120,000 per month. The range reflects significant variation in case mix: a firm focused on high-value catastrophic injury cases can generate $5M from far fewer cases than an auto-focused firm, and may spend less on lead generation as a result.

Typical Channel Mix

Channel diversity increases at this level. A common configuration:

• Google Ads: 30–45% of budget
• LSA: 10–15%
• Lead vendors (2–4 active): 30–40%
• Social media ads: 5–15%
• Referral and content programs: 5–10%

TV and radio spending begins to appear at this level, particularly for firms in mid-size markets where broadcast advertising remains cost-effective. Digital remains dominant for most, but the mix is more varied.

Key Characteristics

Firms at $5M often have a dedicated marketing manager or director for the first time, though they may still rely heavily on agency partners for channel management. Vendor management starts becoming complex — tracking four or five vendors manually is feasible but time-consuming. Partners want to see ROI data but often don't have systems to produce it reliably. This is the level where attribution pain is most acutely felt.

Firms at $10M Annual Revenue

At $10 million annually — approximately $833,000 per month — lead generation budgets typically range from $100,000 to $250,000 per month. Marketing spend as a percentage of revenue often stabilizes or slightly decreases at this level as organic and referral channels mature and paid channel efficiency improves.

Typical Channel Mix

The channel portfolio is more mature and deliberately constructed:

• Google Ads: 25–35%
• LSA: 8–12%
• Lead vendors (3–6 active): 30–40%
• Social and programmatic: 10–15%
• TV/radio (where applicable): 10–20%
• Content and SEO investment: 5–10%

Firms at this level often have multiple active vendor contracts and are making monthly or quarterly decisions about which vendors to increase, cut, or renegotiate. Budget allocation decisions at $200,000/month carry real consequences — a 20% reallocation is $40,000 that needs to be justified.

Key Characteristics

A dedicated marketing director is standard, often with one or two marketing coordinators. Agency relationships are more formal, with monthly reporting expectations. Partners are increasingly engaged in marketing ROI conversations. The need for cost per case visibility by vendor is acute — the manual tracking approach that worked at $2M is no longer sustainable, and budget decisions are being made on incomplete data.

Firms at $20M Annual Revenue

At $20 million annually — about $1.67M per month — lead generation budgets typically range from $200,000 to $500,000 per month. Some high-growth firms spend above this range. The marketing operation at this scale is a serious organizational function.

Typical Channel Mix

At $20M, firms have typically identified the channels that perform best in their market and allocated heavily to those, while maintaining a testing budget for new channels:

• Google Ads: 20–30%
• LSA: 5–10%
• Lead vendors (5–10+ active): 30–40%
• TV/OTT/streaming: 15–25%
• Social and programmatic: 10–15%
• Content, SEO, referral programs: 5–10%
• Testing allocation: 5–10%

Key Characteristics

Marketing teams at this level include a director plus two to five specialists. Agency relationships are managed by the director with formal review cycles. Managing partner involvement is at the strategic level — reviewing quarterly dashboards, approving annual budgets — rather than day-to-day decisions.

Attribution and reporting are no longer optional luxuries. At this scale, a 10% improvement in cost per case efficiency across the portfolio is worth $20,000–$50,000 per month. The ROI of good data systems is unambiguous.

How Channel Mix Shifts as Firms Scale

A few patterns are consistent across firm sizes:

• Google Ads becomes a smaller share of budget as firms grow. Not because it performs worse — it's often the most reliable channel — but because other channels scale more easily. Google Ads has diminishing returns in most markets; lead volume doesn't scale proportionally with spend above certain levels.
• Vendor diversification increases with firm size. Larger firms have more negotiating leverage and more intake capacity to absorb multiple lead streams. They can afford to test more vendors and run them in parallel.
• Broadcast and out-of-home advertising appears later. TV, radio, and billboard spending is more common among larger firms because the economics require scale. Building brand recognition through broadcast requires sustained investment; the payoff is long-term case volume and referral rates, not immediate CPL improvements.
• Content and SEO investment tends to lag where it should be. Organic search is one of the highest-value long-term channels for PI, but it requires sustained investment before it produces results. Many firms underspend here because the ROI timeline is longer than paid channels.

The One Constant Across Revenue Levels

Regardless of firm size or marketing budget, the single biggest determinant of marketing efficiency is whether the firm knows its cost per case by source. Firms that have that visibility can optimize their budget continuously. Firms that don't are making allocation decisions without the information they need.

The reporting requirements change as firms scale, but the fundamental need — to know which channels and vendors are producing cases at what cost — is constant from $2M to $20M and beyond.
