SaaS Subscription vs. One-Time Purchase: The 5-Year Cost Breakdown

2026-07-186min

Using 50 stores as an example, break down initial investment, upgrade costs, operational expenses, and flexibility to provide a reusable calculation template.

1Is the annual subscription more expensive than a one-time purchase?

Perpetual licensing incurs hidden costs in upgrades and maintenance: major version upgrade fees, server hosting, and dedicated support accumulate annually. Subscription models bundle these into an annual fee and allow scalable adjustments at any time.

2Solution: 5-Year Projection Table

For example, with a 50 store: the buyout model requires an initial investment of approximately ¥60 for hardware and software, plus annual maintenance and upgrades of about ¥8; the subscription model charges per store annually, starting at ¥5–¥10 in the first year, with additional costs as you expand.

3Data Validation: Focus on Exit Costs

Confirm that historical data can be fully exported, and devices remain usable or portable after subscription expiration to avoid vendor lock-in.
