Introduction: Are you tired of making monthly payments?
"Another software bill this month..."
"I don't use it often, but I might use it someday, so I can't cancel."
"Before I knew it, the monthly fee alone was over 50,000 yen."
For those of you who are having these kinds of concerns.
Did you know that SaaS tools actually come with a "one-time purchase" option? Overseas, this is called a "Lifetime Deal" (LTD) and is gaining a lot of attention among startups and freelancers.
What is one-time purchase software (LTD)?
A new option that you can pay once and use forever
A lifetime deal is a pricing model where you pay a one-time fee and can use the software forever . There are no monthly or yearly fees, and you can continue to use it for as long as the service is available.
Key points:
One-time payment : First payment only, no additional fees
Permanent access : Available for as long as the service lasts
Updates included : In most cases, future updates are also provided for free.
Why do companies offer one-time purchases?
There are actually strategic reasons for this:
Early funding : Startups get money quickly
Rapid user base growth : Acquire a large number of users in a short period of time
Gathering feedback : Gather valuable input from enthusiastic early users
Difference from subscription: How much better is it?
See the real savings
item | One-time purchase (LTD) | Subscription type |
Initial cost | 15,000 yen (one-time only) | 3,000 yen per month |
Total amount after one year | 15,000 yen | 36,000 yen |
Total amount after 3 years | 15,000 yen | 108,000 yen |
Savings (3 years) | - | Save 93,000 yen! |
If you use multiple tools, such as project management tools, design software, and SEO tools, saving hundreds of thousands of yen per year is not a dream.
It's commonplace overseas! LTD success stories
The LTD movement is spreading worldwide
In fact, overseas, LTD (Lifetime Deal) has already become a major purchasing method .
Representative platforms:
AppSumo : Over 1.5 million users and over $1 billion in cumulative sales
StackSocial : 2 million members
Dealify : Europe's largest LTD platform
Examples of tools provided in practice
Examples of LTD prices for famous tools:
Notion Alternative : $20/month → $59/month (Save 95% for Lifetime)
Canva-like design tool : $15/month → LTD $49
SEO analysis tool : $99/month → LTD $299
Email automation tool : $50/month → LTD $149
These tools have been purchased by tens of thousands to hundreds of thousands of users at LTD and are actually being used.
The three major benefits of one-time purchase software
1. Overwhelming cost reduction
The longer you use it, the more you save. Overseas, there are many reports of people being able to reduce their software costs by more than 90% annually.
2. Stable management with zero fixed costs
Eliminating fixed monthly costs means:
Improved cash flow
Easier to plan your budget
Free yourself from subscription fatigue
3. Early Access Benefits
Many one-time purchases are offered in the early stages of new services:
Early access to the latest AI technology
The development team is close, so feature requests are easily accepted.
Disadvantages to know
1. Initial investment hurdles
The biggest issue is the initial cost, but if you consider that you can use it forever for just three months' worth of monthly fees, it's not that expensive.
2. Risk of Service Termination
As these services are often provided by startups, there is a chance that they may close down, but you can minimize the risk by choosing a trusted platform or a company with a proven track record.
3. Restrictions on some functions
There may be limits on the number of API calls and storage capacity, so be sure to check before purchasing.
Recommended for:
Particularly suitable for:
Those who plan to use the same tool for more than 3 years
Small business owners who want to reduce fixed costs
Freelancers who use multiple tools
Want to try out new tools early?
People who should carefully consider:
Short-term use of less than 3 months
Those who always need the latest features
Three checkpoints before purchasing
1. Calculate your break-even point
Consider how often you use the service and see if LTD is really a good deal.
2. Check the reliability of the company
Number of users and review ratings
Update frequency (ideally at least once a month)
Active community
3. Check the Terms of Use
Details of function restrictions
Data export function
Definition of "lifetime" (usually the service lifespan)
