Key Takeaways
- Neither model is always cheaper. Subscriptions usually win for small teams and short horizons. One-off pricing tends to win as headcount and time horizon grow.
- Compare total cost of ownership (TCO) over 5 years, not the first invoice. Include implementation, support, hosting, upgrades and internal IT time.
- A simple break-even formula shows the headcount at which a one-off purchase pays back.
- The worked example below uses illustrative numbers only. They are not Kunos or any other vendor’s prices.
Software pricing looks simple until you have to compare it. One vendor quotes a small monthly fee per user. Another quotes a single larger figure and says “no monthly fees”. Which one costs less? The honest answer is “it depends”, but you can make it depend on numbers instead of instinct.
This guide shows how to compare one-off and subscription business software over five years, with a formula, a worked example, a hidden-cost checklist and a decision guide. It is written for finance, HR and IT leads in Malaysian organisations weighing systems such as Kunos, our AI-powered business operating system.
Is one-off software cheaper than a subscription?
One-off software is often cheaper over five years for organisations with many users and stable needs, because the cost does not scale with headcount. Subscriptions are usually cheaper for small teams, short projects or fast-changing requirements, because they need little upfront cash and shift upgrades to the vendor. The crossover point depends on your headcount, price per user and the ongoing costs of the one-off option.
How do you calculate the 5-year cost of business software?
Use total cost of ownership: the purchase price plus every cost of running the system across its life. IBM describes TCO as covering direct costs, such as the purchase price, and indirect costs, such as time spent adjusting to new systems. Here is a practical version for each model.
| Model | 5-year cost formula |
|---|---|
| Subscription | (Users × price per user per month × 60 months) + add-on modules + expected price rises + implementation and training + internal admin time |
| One-off | Licence or system fee + implementation and training + annual support, hosting and maintenance × 5 + upgrades + internal IT time |
For a fair comparison, use the same scope on both sides: same modules, same users, same integrations, same support level. Where costs land in different years, BDC notes it is worth adjusting future costs to today’s value, because the timing of money matters. Ask your finance team whether to include that adjustment.
What does a 5-year comparison look like? A worked example
Illustrative assumptions only, not real prices: the subscription costs RM10 per user per month. The one-off system costs RM60,000 for licence and setup, plus RM6,000 a year for support and hosting, and its price does not change with the number of users. Both cover the same modules.
| Users | Subscription over 5 years | One-off over 5 years | Cheaper option |
|---|---|---|---|
| 50 | RM30,000 | RM90,000 | Subscription |
| 100 | RM60,000 | RM90,000 | Subscription |
| 150 | RM90,000 | RM90,000 | Break-even |
| 300 | RM180,000 | RM90,000 | One-off |
The one-off total is RM60,000 plus five years of RM6,000 support (RM30,000), which comes to RM90,000. The break-even formula is: users = one-off 5-year total ÷ (price per user per month × 60). Here that is RM90,000 ÷ (RM10 × 60) = 150 users. Below 150 users the subscription is cheaper. Above it, the one-off option is.
Now add a price rise. If the subscription increases by 5% each year, the 150-user total grows from RM90,000 to about RM99,461, so the one-off option is already ahead at that headcount. Real contracts vary, so check each vendor’s renewal terms. Also test the other direction: if a one-off price scales with users or modules, the break-even moves.
What hidden costs do people forget?
With subscriptions
- Price rises at renewal, and per-user charges that grow as you hire.
- Paid add-ons for features you assumed were included, such as AI tools, extra storage or integrations.
- Ongoing dependency: if you stop paying, you may lose access and have to migrate your data.
- Data export fees or limits when you leave.
With one-off purchases
- Annual support, hosting and maintenance, which are often not included in the headline price.
- Upgrade costs for new versions, and whether security patches are covered.
- Internal IT time to run on-premise infrastructure, if you choose it.
- Vendor risk: if the vendor stops supporting the product, you carry the migration cost.
With both
- Implementation and data migration.
- Staff training and change management.
- Integrations with accounting and other systems. See how this works in our guide to integrating AutoCount or SQL Accounting with your HR system.
- Security and compliance work. Hosting choices affect your PDPA risk. Use our PDPA checklist for HR software when you compare vendors.
How should you decide between one-off and subscription pricing?
| Choose one-off when… | Choose a subscription when… |
|---|---|
| Headcount is large or growing, so per-user fees multiply. | Your team is small and growth is uncertain. |
| Your processes are stable and you want predictable long-term cost. | Your needs are changing fast and you want flexibility to switch. |
| You need data control, such as on-premise or regional hosting. | You want the vendor to handle hosting, updates and scaling. |
| You can plan a larger upfront investment and have budget for support. | You need low upfront cost or prefer operating expenditure. |
| You plan to use the system for 5 years or more. | You may replace the system within 2 to 3 years. |
Ask your finance team and tax adviser how each model is treated in your accounts and for tax. That treatment can change the real cost, so this guide does not assume it either way.
Questions to ask every vendor
- What exactly is included in the price: modules, users, storage, AI features, integrations?
- What are the annual support, hosting and upgrade costs, in writing?
- What happens to price at renewal, and how much notice do we get?
- Can we export all our data in a usable format if we leave?
- Who owns the customisations and configurations you build for us?
- What is the implementation timeline, and what does it cost?
- Where is our data hosted, and can we choose?
- Can you model our 5-year cost using our real headcount?
How does Kunos pricing work?
Kunos is offered as a one-off system investment tailored to your organisation, with no monthly subscription fees. There are three tiers. Core covers dashboard and reporting plus staff and leave management, with AI Document OCR and Finance & Inventory as optional add-ons. Operations adds AI Document OCR and custom workflows. Enterprise adds Finance & Inventory, custom workflows and a dedicated manager. Modular AI SmartPacks can be added to any tier.
Kunos pricing is set through a personalised demo rather than a public price list, so the numbers above are for method only. When you request a quote, use the formula in this guide and ask about annual support, hosting and upgrade terms so you can compare like for like. A one-off model is not automatically cheaper for every organisation, and we would rather you model it than take our word for it. Most organisations are configured and running within 2 to 6 weeks. Kunos also fits organisations that need on-premise or regional cloud hosting, including government-linked companies.

Frequently Asked Questions
Is one-off software cheaper than a monthly subscription?
Not always. One-off software tends to be cheaper over five years for organisations with many users and stable needs, because cost does not grow with headcount. Subscriptions tend to be cheaper for small teams and short horizons. Work out your break-even point using your own numbers.
How do I calculate the break-even point?
Divide the one-off 5-year total by the subscription cost per user over 5 years. In formula form: users = one-off 5-year total ÷ (price per user per month × 60). Below that headcount the subscription is cheaper. Above it, the one-off option is cheaper.
What is included in total cost of ownership for business software?
Total cost of ownership includes the purchase or subscription price, implementation, training, integrations, annual support and hosting, upgrades, security and compliance work, and internal staff time. Count both direct and indirect costs across the whole period.
Does one-off pricing mean there are no ongoing costs?
No. One-off pricing usually removes monthly licence fees, but you may still pay for support, hosting, maintenance and upgrades. Ask for these in writing so you can compare properly.
Is Kunos a subscription or a one-off purchase?
Kunos is offered as a one-off system investment with no monthly subscription fees, tailored to the organisation. Pricing is confirmed through a personalised demo. Ask about annual support, hosting and upgrade terms when you request a quote.
How long should I compare software costs over?
Five years is a common horizon for core business systems, because it is long enough to capture renewals, support and upgrades. If you expect to replace the system sooner, use a shorter period.
