- outright purchase, with free major and minor upgrades for life
Subscription payments and purchase + maintenance are nice, if you can get them. They give a more predictable cash flow for a business and you can generally charge a higher lifetime price than you can with a single payment. But this isn’t appropriate for all types of software. For example, it doesn’t make much sense for lower priced desktop software. Assuming subscription or purchase+maintenance isn’t an option, the question boils down to – should we charge for major upgrades?
Let’s look at the numbers for a simple (contrived) example. AcmeSoft sells 1000 licences of v1 of their product in year 1, 2000 licences of v2 of their product in year 2, 3000 licences of v3 of their product in year 3 etc. Each year 50% of the customers who bought the previous version (new or as an upgrade) pay to upgrade to the latest version. The upgrade costs them 50% of the initial purchase. How much is the upgrade revenue worth? We can create a simple model in Excel:
Income new licences (blue) vs income from upgrades (red). Click to enlarge.
Percentage of annual income from upgrades. Click to enlarge.
In year 8 the upgrade income is actually worth more the new licence income. By year 10 upgrades are worth some 60% of yearly income for the product. If the product has a 10 year lifespan, nearly 50% of the total income from the product will be from upgrades. So it only makes commercial sense to give free upgrades for life if this will at least double the conversion ratio. This seems highly unlikely. You can always try changing your upgrade policy and measure what effect it has on your conversion rate. Not much, I would guess (if anyone has tried it, I would be interested to know the results).
Even in a more pessimistic model where only 30% of customers upgrade and they only pay 30% of the new licence fee, upgrades still account for nearly 25% of total income over 10 years. You can download the spreadsheet and play with the parameters yourself.
Upgrade income becomes particularly important when:
- A product has a long life span.
- Customers are very likely to upgrade to a new version.
- There is little growth in new sales.
In the worst case you could end up with a product with a huge customer base built up over a long period, but which makes very few new sales as it has saturated the market. Free major upgrades would mean that each major release is then going to result in large expense (developent and support) but very little income. Microsoft must be very happy they didn’t offer free upgrades for life on Windows or Office!
I don’t see anything unreasonable about charging for major upgrades. The vendor has to do additional work to add the new features and existing customers can choose whether the new features are worth the upgrade fee. However customers have certain (not unreasonable) expectations for paid upgrades:
- The fact that the customer is expected to pay for major upgrades needs to be made clear before purchase.
- Any major bugs in version n should be fixed before releasing version n+1.
- A major upgrade should have significant new features.
- Major upgrades should not be released more than once every 12 months.
- The upgrade fee should be reasonable. Around 40% of the cost of a new licence seems typical.
- There should be a grace period for free upgrades. E.g. If I buy v1 of a product on 01-Jan I don’t expect to have to pay an upgrade fee for v2 released on 02-Jan. Typically this grace period is 3-6 months.
If you are offering free upgrades for life currently, you can change your policy to paid major upgrades. But, obviously, you will need to honour free upgrades for everyone who purchases before the change of policy.
There are some, apparently successful, companies that offer free upgrades for life (Axialis for example). But I have heard many tales of small software vendors regretting their initial decision to give free upgrades for life. The easiest customer to sell to is the one you already have. If you don’t charge for major upgrades, are you leaving large amounts of money on the table?
Ignoring inflation, interest etc.
