Per-Unit vs. Flat vs. Per-User Pricing Explained

The best pricing model depends on how many units you manage, how many people use the system and how fast you expect to grow. Per-unit pricing suits portfolios that change size often, flat tiers suit owners who sit comfortably inside a band, and per-user pricing suits a very small team managing many doors. The way to decide is to calculate the break-even point between models using your own numbers, not to rely on the headline rate.

All figures here are illustrative. Replace them with current prices from the vendors you are comparing.

Per-unit pricing

You pay a rate for each unit each month. Some vendors define a unit as any leasable space, others count only occupied or active leases.

Strengths

• Cost tracks your portfolio. Acquire ten units and the bill rises by a known amount.
• Easy to budget per door, which helps when you set rents and owner management fees.
• Often includes unlimited users, which is helpful if you have several staff or part-time help.

Weaknesses

• Large portfolios can become expensive unless the vendor offers volume tiers.
• Monthly minimums penalize very small portfolios.
• Vacant units may still be billed.

Example. At an illustrative 2.20 dollars per unit, 40 units cost 40 x 2.20 = 88 dollars per month, or 1,056 dollars per year. At 100 units the bill is 220 dollars per month.

Flat-tier pricing

You pay a fixed amount for a band of units, a bundle of features or both.

Strengths

• Predictable. The invoice does not change when a lease turns over.
• Cheaper than per-unit if you sit near the top of the band.

Weaknesses

• Price jumps when you cross the band boundary.
• You may pay for headroom you never use.
• Features can be locked to higher tiers.

Example. An illustrative flat plan costs 110 dollars per month for up to 50 units and 190 dollars for 51 to 100 units. At 50 units you pay about 2.20 dollars per unit. At 51 units you pay 190 dollars, about 3.73 dollars per unit, a big jump caused by one extra door.

Per-user pricing

You pay for each seat. Units may be unlimited or capped.

Strengths

• Excellent for a one- or two-person operation managing many units.
• No penalty for growth in the number of properties.

Weaknesses

• Cost climbs as you add assistants, bookkeepers or maintenance coordinators.
• Some vendors charge for read-only or owner-portal users.
• Pressure to share logins, which is a security and audit risk.

Example. At an illustrative 45 dollars per user per month, a two-person team pays 90 dollars regardless of whether it manages 40 or 200 units. A five-person team pays 225 dollars.

Side-by-side comparison

Finding the break-even point

Break-even is the unit count at which two plans cost the same. For a per-unit plan with rate r and a flat plan with price F, break-even is F divided by r.

Worked example (illustrative). Per-unit rate 2.20 dollars, flat plan 110 dollars. Break-even = 110 / 2.20 = 50 units. Below 50 units the per-unit plan is cheaper. At 50 units they tie. Above 50 units the flat plan is cheaper only until its cap is reached.

For a per-user plan against a per-unit plan, set users x seat price = units x unit rate. With 2 users at 45 dollars (90 dollars) and a per-unit rate of 2.20 dollars, break-even is 90 / 2.20, about 41 units. A two-person team with more than 41 units would pay less on the per-user plan, while a team with fewer units would pay less on the per-unit plan.

Use the monthly cost estimator to test several rates in a row, and keep a note of the result for the next renewal.

Hybrid models

Many vendors blend the models: a platform fee plus a per-unit rate, a per-unit rate with a user cap, or a flat tier with paid add-ons. For hybrids, calculate each component separately and sum them. A low per-unit rate with a high platform fee can look cheap until you divide the total by your unit count.

How growth plans change the answer

Estimate your unit count at three points: today, in twelve months and in thirty-six months. Calculate the cost under each model at each point, then choose the model that wins over the period you expect to stay. If you plan to sell units or lose a large building, include that too, since per-unit pricing falls when your portfolio shrinks and flat tiers may not.

Also factor in how the vendor treats volume. Ask whether the per-unit rate steps down at stated thresholds, and whether the step applies to every unit or only to the units above the threshold. The difference can change the annual bill noticeably.

Questions to ask each vendor

1. What exactly counts as a unit, and are vacant or off-market units billed?
2. Which features are in my tier, and what is the price of the next tier up?
3. Are owner, tenant and vendor portal users free?
4. Is there a monthly minimum or a platform fee?
5. What happens to the price at renewal?

When to consult a professional

If you are choosing a model for a firm that manages other owners' properties, ask your accountant how to allocate software costs across owners and whether any can be charged back under your management agreement.

Frequently asked questions

Is per-unit always cheaper for small landlords?

Not always. Monthly minimums can make the effective rate high for very small portfolios. Compare against flat and free plans.

Why do vendors prefer per-unit pricing?

It ties revenue to the size of your business, so they earn more as you grow. It also keeps the entry price low, which helps marketing.

Can I negotiate a flat price on a per-unit plan?

Larger portfolios often can. Ask for a fixed price for a stated unit range and a cap on renewal increases.
