What to know
- Define the inquiry or matter cohort and reporting date.
- Distinguish revenue return from contribution-based return.
- Use comparable acquisition costs in the calculation.
- Keep practice areas and collection timing visible.
- Label attribution gaps and open matters instead of inventing precision.

Choose the question the calculation should answer
Partners may want to know whether a campaign generated revenue, whether acquisition produced a positive contribution or where the next budget should go. Those questions are related, but they do not use identical measures.
Write the purpose before collecting numbers. A revenue-to-spend ratio can describe revenue associated with a campaign, while a return calculation using contribution addresses a different economic question. Calling both ROI without a definition creates confusion.
Decide which practice and period are being assessed. A blended firm figure can hide differences in matter type, payment structure and the time needed for outcomes to become meaningful.
Use the firm's approved financial records and accounting definitions. Marketing reports should not invent a financial result from a contact count or an assumed average matter value.
Distinguish the financial stages
Recorded or billed revenue is not always the same as cash collected. Contribution is another measure, reflecting the firm's chosen treatment of relevant delivery costs. The calculation should state which figure it uses.
A recently retained matter may not yet have produced a meaningful financial outcome. Keep it visible as open rather than assigning a final value simply because a campaign report needs a number.
If a planning forecast uses expected future value, label it as an assumption-based forecast. Do not mix it with observed collections and present the combined total as money already generated.
The aim is an understandable model. A partner or finance colleague should be able to reproduce the result from the definitions and records supplied.
Use a clearly labeled contribution example
The following figures are hypothetical budget units used only to explain the arithmetic. They are not a benchmark, a Pulse case study or a forecast of legal fees.
| Input | Hypothetical value | Definition |
|---|---|---|
| Acquisition cost | 5,000 units | The stated marketing costs assigned to the cohort |
| Attributable gross contribution | 8,000 units | The defined contribution before acquisition cost |
| Contribution after acquisition | 3,000 units | 8,000 minus 5,000 |
| Simplified return | 60% | 3,000 divided by 5,000 |
The result excludes any costs not included in the stated contribution and acquisition definitions. It should not be called the firm's final net profit return if overhead or other relevant expenses remain outside the model.
A revenue-only ratio would answer a different question. If the model uses revenue before delivery costs, label it accordingly rather than borrowing the contribution-based interpretation.
Keep the cost basis consistent
List the acquisition expenses included: media, provider work, relevant production or other costs within the chosen method. Explain how one-time foundation work is treated so periods can be compared sensibly.
A platform's media-only cost can be useful for account management. It is not automatically equivalent to a complete acquisition cost used for a partner-level decision. Keep the distinction visible.
Do not compare a full quarter of costs with a month of outcomes without explaining the timing. The numerator and denominator need a compatible basis or the resulting ratio has little decision value.
Where costs support several practices, state the allocation method. An imperfect but transparent rule is more useful than a hidden assumption that makes one practice appear unusually efficient.
State the attribution rule
A prospective client can encounter a referral, organic search and advertising before contacting the firm. Decide how the report assigns credit and explain the limits of that choice.
Do not add every platform's claimed conversions and assume the sum represents unique people. Different systems can credit the same journey under different rules. Google documents discrepancies involving attribution, counting, dates and reporting delays.
Use appropriate identifiers and approved systems to connect records without copying confidential legal narratives into marketing tools. The acquisition analysis usually needs an outcome category and source evidence, not the substance of the matter.
Where the source is unknown, retain an unknown category. Guessing creates false precision and can direct future spending toward an unsupported conclusion.
Connect later outcomes only through an appropriate process
Google supports offline conversion approaches for connecting later events with earlier ad interactions. The existence of that capability does not mean every firm has implemented it or that every type of data should be uploaded.
Review current technical guidance, eligibility, privacy requirements and the firm's own obligations before sharing data. Do not assume a generic integration tutorial settles those questions for legal intake.
The business can still use internal outcome reporting where platform uploads are inappropriate or not implemented. A useful partner discussion does not require exposing confidential matter details to an advertising system.
Keep implementation claims accurate. Ask the provider what is actually connected, which event is returned and what remains a manual or internal process.
Interpret the result with practice context
Compare like practices and matter types where they differ materially. A high-volume service with a shorter financial cycle should not silently dominate a blended report and conceal another practice's fit problem.
Look at progression as well as the final ratio. A poor return can begin with unsuitable inquiries, missed intake, low engagement or later financial outcomes. The calculation shows the result under its method; it does not establish the cause by itself.
Use a sensitivity view when assumptions materially affect the conclusion. Show what changes if an open outcome remains uncertain rather than presenting one optimistic value as settled fact. Keep the model understandable and grounded in the firm's records.

Your questions, answered
Is revenue divided by marketing spend the same as ROI?
It is a revenue-to-spend ratio unless the calculation includes and defines the relevant costs for a return measure. Label the method so it is not mistaken for profit or contribution.
Should law firm ROI use billed or collected revenue?
Choose the financial question and use the firm’s approved definitions. Keep billed, collected and contribution measures distinct, especially when timing differs.
How should open matters be treated?
Show them as unfinished and update the cohort as evidence develops. Any expected value should be labeled as a forecast rather than observed financial return.
Can we add conversions from every marketing platform?
Not without reconciling duplicates and attribution rules. Several systems may credit the same prospective client under different methods.
Do we need to upload legal matter details to measure marketing?
A useful internal analysis generally needs defined stages and outcomes, not confidential narratives. Review any data-sharing implementation through the firm’s appropriate technical and professional process.
