Measuring profitable mobile notary services
Measure profitable mobile notary services with contribution per door-to-door hour, including collected revenue, direct costs, unpaid time, and failed bookings.
No service is automatically the most profitable. Profitability depends on geography, calendar, and the service's costs and time demands, not the service label alone.
The same loan signing pays well for a notary ten minutes from three title offices. It loses money for one who drives forty minutes each way to reach the first.
So instead of a ranking, here is the arithmetic that produces your own comparison, using letters rather than invented figures. Fill it in from your records; no outside list can account for your routes, cancellations, and unpaid time.
What to take away
- The measure is contribution per door-to-door hour. Anything measured per job flatters long, distant work and hides the cost of getting there.
- Cancellations belong in the calculation, not in a footnote. A service that fails often is less profitable than its completed jobs suggest.
- Printing-heavy work carries a cost that is incurred before you know whether the job will complete, which is a different kind of risk from ordinary time.
- You need eight to ten completed jobs of a service type before the number means anything.
The variables
Symbol / Meaning
- R
- Revenue collected for one completed job of this type
- D
- Door-to-door minutes, from leaving to returning
- W
- Unpaid minutes afterwards: scanning, uploading, invoicing, chasing
- M
- Miles driven for the job
- K
- Your all-in cost per mile
- P
- Printing and supplies consumed for the job
- C
- Share of bookings of this type that produce no completed act
- L
- Minutes and miles spent on those failed bookings, on average
R is what you actually collected, not what you invoiced. That distinction matters more in this trade than people expect, because some client types pay reliably and some do not.
Variables that drive contribution
- RRevenue collected per completed job
- DDoor-to-door minutes
- WUnpaid minutes afterwards
- MMiles driven per job
The calculation
Contribution for one completed job is: R − (M × K) − P.
Contribution per hour in four steps
- Contribution = R minus (M x K) minus P
- Time = D + W
- Waste per job = (C / (1 minus C)) x L
- Contribution per hour = Contribution / (Time + waste)
Time consumed for one completed job, in minutes, is: D + W.
But a completed job is not the whole picture, because failed bookings consumed time and miles and produced nothing. Include unrecovered costs from failed bookings in the costs you allocate across completed jobs, and include failed-booking time in the total hours.
Then the number to compare across services is: (total revenue collected for completed jobs − total direct costs for completed and failed bookings) ÷ total hours spent on completed and failed bookings.
Do this for each service type you offer. The ranking that falls out is yours, and it will not match anyone else's.
What the arithmetic usually reveals
Three patterns show up often enough to be worth watching for. None is a rule, and each has to be tested against your own numbers.
Short, close jobs with a low failure rate often beat long, distant jobs with a high fee. D is the denominator, and it does not care how impressive the fee looked.
Work booked through an intermediary is often worth less than it appears once W is counted honestly. Someone else's portal, scanning requirements and payment cycle are all your unpaid time.
And a service with a high C can be net negative even when every completed job looks profitable. That is why the cancellation term is in the formula rather than in a comment.
Test all three. The point of writing the arithmetic down is that it can contradict you.
Where the fee comes from, and where it does not
R has two components and they are governed differently. The fee for the notarial act is set by your state's statute, and what you may charge is not a commercial decision. The travel and service charges around it are yours, subject to whatever your state says about how a travel fee is presented or limited.
That split is the pricing question in this trade. The lever you control is the second component and the efficiency of D.
For any state, check its commissioning authority for the applicable cap and fee rules before setting the act charge. In California, that authority is the California Secretary of State.
Collecting the inputs without a new system
You need eight to ten jobs per service type, and you can collect them on paper.
Collecting the eight inputs on paper
- Note departure and return times for D
- Note odometer or mileage log for M
- Weekly unpaid finishing minutes divided by jobs for W
- Log failed bookings with minutes and miles for C and L
- Quarterly vehicle costs divided by miles for K
- Monthly printing supplies divided by jobs for P
Keep it as ordinary business records, following IRS Publication 583, Starting a Business and Keeping Records. Keep it separate from your notarial journal, a statutory record with its own rules. Commercial data does not belong there.
Choose the service types you actually offer and record each separately; the comparison uses your own job mix, not a universal catalog.
What to do with the answer
The result is not an instruction to drop the low scorers. Three cautions.
A service can score badly and still be worth keeping because it brings the client who books the profitable work. Care facility visits and small individual jobs often do exactly this.
A service can score badly because you are new at it. Measure again after the twentieth job before deciding.
And a service can score well and still be one to refuse, because the risk is not yours to carry. Volume does not fix a signing you are not competent to handle.
The reasonable move after the first ranking is usually to change the mix at the margin. Accept more of the top two, decline the bottom one when the calendar is tight.
Record how each booking reaches you as well as the service type; an intermediary can add portal, scanning, and payment work to W. For a sequence for getting the underlying records started, see the gates before taking money.
A word about publishing the answer
Whatever you conclude, be careful about turning it into a claim. Saying a service is the most profitable, or that you are the fastest or cheapest in an area, is an advertising claim and has to be supportable before you publish it. The Federal Trade Commission's Advertising FAQs: A Guide for Small Business explains the rules for advertising claims.
Your own arithmetic is evidence about your own business. It is not evidence about anyone else's, and it does not support a comparative claim.
When the driving is not yours
The whole calculation changes when someone else does the driving. D stops being your time and becomes a wage. That converts a time constraint into a cost, and the services that rank well shift accordingly.
Before assuming it improves the picture, work the numbers again with the labor cost included, and read what a second commissioned notary changes, because the second person cannot act under your commission.
Common questions
Are loan signings the most profitable work?
They carry the highest fee per job in most areas and also the most unpaid time, the heaviest printing, and a real chance of postponement after printing. Whether they win depends on your distance to the source and your failure rate. Run the arithmetic.
Why not just count revenue per appointment?
Because it treats an hour and four hours as the same thing. It is the single most common reason an operator is busy and not earning.
What if I do not have enough jobs to measure?
Then you have a provisional answer and you should say so to yourself. Keep the records, and revisit at eight to ten jobs per type.
Does this apply to remote work if my state allows it?
The structure applies, with D close to zero and different variables in its place, including whatever the technology and registration cost. Whether remote work is available to you at all is a question for your commissioning office.
