Competitor Seat Fees and Add-Ons: 12-Month TCO (2026)

Summary

Model 12-month TCO of clinic software with per-seat pricing and add-ons using volume scenarios, labour cost, and price escalation. It covers why list price misleads, building the tco model, example: 5-staff clinic, 12-month tco comparison, and price escalation risk.

Real Cost of Competitor Seat Fees and Add-Ons: 12-Month TCO Model (2026)

The advertised price of practice management software is rarely the price you pay. For platforms built on per-seat (per-user) pricing with add-on modules, the gap between the entry-level quote and the actual 12-month cost can be substantial — especially when a clinic grows, adds staff, or discovers that the features they actually need are in higher-priced tiers or separately priced add-ons.

Total cost of ownership (TCO) modelling replaces the vendor's best-case quote with a realistic projection across three volume scenarios: the practice at current size, the practice at expected growth, and the practice at a higher-growth scenario. Running all three produces a cost range rather than a single number, which is a more honest basis for comparison.

This guide covers how to build a 12-month TCO model for clinic software with per-seat pricing and add-ons, using examples from common competitor pricing structures.

Why List Price Misleads

Per-seat pricing escalates with growth

A platform priced at EUR 30 per user per month sounds reasonable for a two-practitioner clinic. At five staff members (two practitioners, two support staff, one manager), the cost is EUR 150/month — EUR 1,800/year. At eight staff members (as the clinic grows), it's EUR 240/month — EUR 2,880/year. The cost has scaled directly with headcount, but the platform's value to the business has not necessarily scaled proportionally.

For clinics in growth mode, per-seat pricing creates a double burden: paying more exactly when you're least able to absorb it (during the investment phase of growth).

Add-ons are often necessary, not optional

Platforms with a low base price frequently gate essential functionality behind add-ons:

Online booking: EUR 15–30/month extra
Client portal: EUR 20–40/month extra
SMS reminders: EUR 10–25/month (or per-message billing)
Reports and analytics: EUR 15/month extra
Multi-location support: EUR 20–50/month extra

The "starter" package that looked affordable at EUR 30/user/month quickly becomes EUR 80–100/user/month when essential features are added. The comparison should be total functional cost, not base price.

Annual commitment and lock-in

Many per-seat platforms offer a significant discount for annual commitment (20–30% discount). This sounds attractive, but it also means 12 months of minimum payment regardless of whether the software meets expectations. If the platform disappoints in month three, you're paying for nine more months regardless. The discount should be weighed against the lock-in risk — especially for a growing clinic that may outgrow its initial requirements faster than expected.

Building the TCO Model

Step 1 — Define volume assumptions

For each of the three scenarios, define:

Number of users (staff who need active accounts)
Appointment volume per month
Number of locations
Modules required (online booking, SMS, portal, multi-location, reports, etc.)

Conservative scenario: Current headcount, current locations, all essential features. Expected scenario: Current headcount +2 staff, same locations, all essential features + one or two growth features. Growth spike scenario: Current headcount +5 staff, two locations, full feature set.

Step 2 — Calculate per-scenario costs

For each scenario and each platform being evaluated, calculate:

Cost line	How to calculate
Base subscription	Base price × seats × 12 months
Add-on modules	Sum of required add-ons × 12 months
Per-message / per-transaction fees	Estimated volume × per-unit rate × 12 months
Implementation / onboarding	One-time fee (often waived at higher tiers)
Training	One-time cost or included
Support tier	Basic (often email-only) vs. priority (phone)
Annual commitment discount	Subtract if committing annually

Step 3 — Include internal labour cost

The software's direct cost is only part of the TCO. Internal labour — staff time spent on administration that the software either automates or fails to automate — is often the largest line item and the most overlooked.

Estimate time cost for:

Manual workarounds: if the software doesn't support a feature natively, how much staff time per week is spent on the workaround? (e.g., manually SMS-ing appointment reminders: 30 minutes per day = 26 hours per quarter = EUR 650 at EUR 25/hour)
Data reconciliation: exporting data from one system and importing to another, or reconciling between disconnected modules
Software administration: user management, configuration changes, report generation that requires manual steps
Support time: time spent on calls with the vendor's support team, waiting for responses, and implementing workarounds for bugs

EUR 25/hour × 5 hours/week = EUR 6,500/year in internal labour cost — a number that is invisible in the software pricing comparison but is very real in the P&L.

Example: 5-Staff Clinic, 12-Month TCO Comparison

Assumptions: 5 users, 1 location, features required: appointments, client management, online booking, SMS reminders, billing, basic reports, client portal.

Competitor A (per-seat model):

Cost item	Monthly	Annual
Base plan (EUR 35/user/month × 5)	EUR 175	EUR 2,100
Online booking add-on	EUR 25	EUR 300
Client portal add-on	EUR 30	EUR 360
SMS reminders (per-message, 500/month × EUR 0.08)	EUR 40	EUR 480
Reports (basic included; advanced EUR 20/month)	EUR 20	EUR 240
Total	EUR 290	EUR 3,480

At 8 staff (growth scenario), the base plan scales to EUR 280/month (EUR 3,360/year in base alone), bringing the total to EUR 4,740/year.

Tregovia (flat rate):

Cost item	Monthly	Annual
Base plan (up to 2 staff, up to 100 clients (extra users EUR 10/month per 5 seats))	EUR 47	EUR 564
Online Booking module	Included in base plan	EUR 0
SMS module availability	Included in base plan; message usage billed separately	Usage-dependent
Reports (included in base)	EUR 0	EUR 0
Total	EUR 55	EUR 660

At 8 staff, 6 additional users require 2 extra-user packs (EUR 10/month each): EUR 47 + EUR 20 = EUR 67/month before SMS usage, payment costs, or optional modules.

Price Escalation Risk

Per-seat software pricing is subject to annual price increases. A platform that charges EUR 35/user/month today may charge EUR 42/user/month in two years. For a 10-user team, that's a EUR 840/year increase — without any additional feature delivered.

Base-plan plus seat-pack pricing models make this risk easier to model: growth in team size maps to published seat packs instead of a separate full-price subscription for every user.

In the TCO model, include a price escalation sensitivity test: what does the 12-month cost look like if the vendor increases the per-seat price by 20% after the annual commitment period?

Setting Up in Tregovia

Tregovia's pricing model is designed to eliminate per-seat escalation:

EUR 47/month base plan: Up to 2 staff accounts and up to 100 clients. All baseline modules included. Additional users beyond 2 are available in 5-seat packs at EUR 10/month per pack, so a team of 7 needs 1 extra pack (EUR 57/month total), and a team of 12 needs 2 extra packs (EUR 67/month total).

Module pricing (pay for what you need):

Online Booking: included
Follow-up Sequences: EUR 8/month
Memberships: EUR 12/month
Unified Inbox: EUR 12/month
White Label: EUR 99/month

Module prices are published monthly add-ons. Check staff limits, client limits, SMS usage, and payment-processing costs when comparing total monthly cost.

What's included in the base plan: Clients, appointments, billing, estimates, discounts, refunds, reports, SMS, calendar sync, data import, support tickets. No add-ons required to access core functionality.

14-day free trial: Trial access for evaluation. Confirm which optional modules and usage limits are enabled in the trial before comparing against paid plans.

FAQ

Why does the advertised price often differ so much from the actual 12-month cost?

Because most per-seat software platforms advertise their entry-level price — the lowest tier, fewest seats, minimum features — which is rarely the configuration a growing clinic actually uses. The useful comparison is total cost at the configuration the clinic will actually run: realistic seat count, all required modules, SMS billing at expected volume. Running this comparison for three volume scenarios (conservative, expected, growth) produces the range of likely actual cost over the next 12 months — a far more useful number than the advertised starting price.

What internal labour costs should be included in a TCO model?

Any staff time spent on tasks that the software either automates or fails to automate. The most material items: manual workarounds for missing features (time spent doing manually what the software should do automatically), data reconciliation between disconnected systems, and support time (time spent on vendor calls or waiting for bug fixes). In a well-run 5-staff clinic, these costs typically add EUR 2,000–5,000 per year to the real cost of inadequate software — costs that never appear in a software pricing comparison but are visible in the time tracking data.

How should clinics account for lock-in risk in the TCO model?

Include a "switching cost" estimate in the conservative scenario: if the software disappoints, what would it cost to switch? Typically: remaining months of the annual commitment (if any), data migration cost, staff retraining time, and the operational disruption during transition. A EUR 3,000/year platform with a EUR 2,000 switching cost has a real minimum commitment of EUR 5,000 for the first year. A month-to-month platform with no minimum commitment has a switching cost of essentially zero. This asymmetry should be visible in the TCO model.

Is flat-rate pricing always better for clinics?

Better for clinics that expect to grow or that have variable staffing. Per-seat pricing is most cost-effective for very small, stable teams with limited feature requirements — a solo practitioner with one support staff member who needs only basic scheduling and billing may find a well-priced per-seat tool adequate. The crossover point — where flat-rate pricing becomes cheaper than per-seat pricing — depends on the specific platforms being compared, but for most clinics with five or more active staff accounts, the flat-rate model produces a lower 12-month cost. Run the numbers for your specific team size before deciding.

What is the most common error in clinic software TCO analysis?

Comparing only the base subscription costs, ignoring add-ons and usage fees. A clinic that compares "EUR 35/user/month" against "EUR 47/month flat" and concludes the per-seat option is cheaper for their four-person team (EUR 140/month vs. EUR 47/month) is missing the EUR 75–100/month in add-ons that the per-seat platform requires to match the feature set included in the flat-rate plan. The correct comparison: what does it cost to get the functionality you need from each platform, at your team size, over 12 months? The answer almost always differs significantly from the comparison of base prices alone.
