Pay-Per-Plan vs. Subscription: How Estate Planning Software Pricing Actually Works

You’re looking at a pricing page for estate planning drafting software. One vendor wants $600 a month. Another charges $100 every time you generate a plan. Neither page tells you which is cheaper for your practice, because neither one knows the only number that decides it: how many estate plans you actually produce in a month.

That’s the whole thing. Estate planning software pricing looks like a comparison of two numbers. But it’s really a bet on your own volume, and most attorneys place that bet without doing the math.

One quick clarification, because the words overlap: this is about what a software vendor charges you, not what you charge clients. If that’s the question on your mind, start with how flat-fee billing changes your practice economics.

It’s also worth knowing before you shop: 55.4% of solo firms told the ABA they have no technology budget at all, and document assembly adoption among solos has sat flat at 37%. Most people reading this are buying in this category for the first time.

The Four Ways Drafting Software Gets Priced

Estate planning drafting software is priced four ways: per-seat subscription (a flat monthly fee for each user); pay-per-plan (a fee charged each time you generate a document set); tiered subscription (a monthly base that includes a set number of drafts plus an overage rate); and hybrid (where one vendor offers both and lets you choose).

Tiers exist for a reason, and it isn’t generosity. Harvard Business Review’s good-better-best framing explains it: a low tier pulls in price-sensitive buyers, a high tier captures the ones willing to spend more, and the middle tier is where the vendor wants you. That doesn’t make tiers bad. It just means the middle option isn’t neutral.

Price is one evaluation axis. What the software actually does with your data — deterministic estate planning document drafting — is arguably the more important one.

How to Find Your Crossover Point

Your crossover point is the monthly plan volume at which a subscription becomes cheaper than paying per plan. To find it, divide the subscription’s monthly price by the per-plan price. That’s how many plans you need to produce each month before the subscription starts winning. Below that number, you’re paying for drafts you didn’t make.

Monthly subscription ÷ plans per month = your effective cost per plan

Run it both directions with illustrative numbers — say a subscription at $300 a month against pay-per-plan at $75 a plan.

At 3 plans a month. The subscription costs $300 ÷ 3, or $100 per plan. Pay-per-plan costs $225 total. Pay-per-plan wins by $75 a month, and by more in any month you draft nothing.

At 14 plans a month. The subscription costs $300 ÷ 14, or $21.43 per plan. Pay-per-plan costs $1,050. The subscription wins by $750 a month — $9,000 a year you didn’t know you were spending.

The crossover there is $300 ÷ $75 = 4 plans a month. Four and up, subscribe. Three and under, pay per plan. Tiered pricing makes that one step longer, not harder: base fee plus overage rate times any plans beyond what’s included, compared to your per-plan alternative at the same volume.

Now the part most attorneys don’t think to do is running the calculation on your slowest month, not your average. A fixed monthly fee is a fixed monthly fee in February. If your volume swings between 2 and 12 plans, your average of 7 is a number that never actually happens. Decide whether you can absorb the subscription in the 2-plan month, because that’s the month that will make you resent the line item.

If you want to go past cost comparison into what the tool returns, you can run the full ROI calculation on a drafting tool separately. This section is about which price tag is smaller. That one is about whether either is worth paying.

The Costs That Aren’t on the Pricing Page

The sticker price is rarely the price. Five costs routinely appear after you sign: implementation fees, charges for additional users, template migration, annual contract minimums, and renewal increases. Any one of them can swamp the difference between two vendors’ monthly rates in year one.

Onboarding and implementation. Some vendors charge a one-time setup fee — sometimes several hundred dollars, sometimes several thousand. The SBA’s framing helps: separate one-time costs from recurring ones before you compare anything. A $500 setup fee on a $200/month tool is a 21% increase in year one and zero in year two.

Per-seat charges. “Per-seat” means per person. If your paralegal needs her own login and the plan bills per seat, your $200 tool is a $400 tool. Ask how many seats the base price includes and what each additional one costs.

Template migration. If you’re bringing your own template set, ask who converts it, how long it takes, and what it costs. Then ask what happens when you need to change a clause next year. Keeping your template set current and consistent is real work whether or not the vendor prices it as a line item.

Annual commitment. Monthly pricing advertised at the annual rate is common. Check whether the discount requires a 12-month term, and what exit looks like if the tool doesn’t fit.

Renewal increases. Ask, in writing, how much the price can rise at renewal and with how much notice. Vendors that won’t answer are telling you something.

Then there’s the cost that never appears on an invoice. BLS puts the median lawyer wage at $159,670 a year, or $76.76 an hour, as of May 2025. Every hour spent re-keying client data into a template is priced at your rate, not the software’s — which is why the unbilled hours manual drafting already costs you are the real baseline you’re comparing against.

One practical note: software is generally a deductible business expense for a law practice, which changes the after-tax math. IRS Publication 334 covers the general rules for small businesses. Talk to your accountant before treating that as a discount.

When Pay-Per-Plan Is the Right Call

A pure pay-per-plan is right when your volume is low, lumpy, or unknown. It turns a fixed cost into a variable one, so a slow quarter costs you nothing instead of costing the same as a busy one. For a practice with uneven cash flow, that’s not a small thing.

It fits three situations cleanly:

• You produce fewer than four or five plans a month. Below the crossover, the arithmetic is simply on your side.
• You’re new. A first-year practice can’t forecast volume, and guessing wrong on a tier is expensive in both directions.
• You’re testing. Paying per plan is the cheapest way to learn whether a tool fits your workflow before committing a year to it.

The honest counterpoint: pay-per-plan is the most expensive model per unit, and it stays that way. At 14 plans a month in the example above, you’re paying roughly three and a half times what a subscriber pays per plan. If your volume grows and your pricing doesn’t change with it, you’re funding someone else’s discount.

If that’s you, estate planning software built for solo practitioners is the right starting point — right-sized tools, low setup, no obligation to buy capacity you won’t use.

When a Subscription Is the Right Call

A subscription is right when your volume is predictable and above your crossover point. At 10 or more plans a month, the effective cost per plan drops far enough that the fixed fee stops looking like overhead and starts looking like a discount you take on every matter.

Three signals you’re there:

• Predictable volume above the crossover. Six months of consistent output, and you can name your floor.
• More than one producer. An attorney and a paralegal both drafting usually pushes you past per-plan pricing fast.
• You need budget predictability. A known monthly number is easier to plan around than a variable one, even when the variable one occasionally costs less.

That last point is also the counterpoint. Fixed costs don’t care about your quarter. If your practice has a genuinely slow season, you’ll pay full freight through it. Decide in advance whether that’s a trade you’ll make.

Most firms hit this transition while dealing with several others at once — those are the growing pains that push firms past per-plan pricing, and pricing is usually the smallest of them. If you’re staffing up, what a growing estate planning firm needs from software is a broader question than cost per plan.

What Estate Engine Charges (And Why We Offer Both)

We’ll be direct, since the rest of this has been. Estate Engine runs a hybrid model, which is the honest reason we can explain both sides without picking one.

Pay-as-you-go is $50 per plan generated, with no monthly commitment. You’re billed when a client completes intake and a draft is generated — not for having an account.

The subscriptions are tiered with included drafts and a lower overage rate at each level:

• Starter at $200/month for 5 included drafts and $40 per additional draft
• Growth at $420/month for 12 drafts and $35 per additional
• Scale at $597.50/month for 20 drafts and $30 per additional.
• Enterprise is custom for firms well past 20 plans a month.

(Current figures live on our pricing page.)

Run the crossover on those yourself. Starter divided by pay-as-you-go is $200 ÷ $50 = 4 plans a month. Under four, pay-as-you-go is cheaper, and we’d rather you use it than buy a tier you don’t need. Over four, the tier is cheaper and the per-draft rate keeps falling as you move up.

We offer both because a solo doing 3 plans in a slow February and 11 in a good June is the same firm, and charging them as though they’re two different customers is how attorneys end up resenting their software.

So before you compare any two vendors, write down your slowest month’s plan count and your busiest. Run both through both models. The answer is usually obvious once it’s on paper, and it’s almost never the answer the pricing page wanted you to reach.
