A finance manager renews a licence she has paid for since 2018. The software sits on one machine in the corner office. When that machine died last winter, the company lost four days finding the installer, the licence key and someone who remembered the configuration.
Cloud software removes that particular failure and introduces different ones. The trade is real, and the marketing on both sides is dishonest about it. Vendors selling subscriptions never mention the five year cost. Vendors selling perpetual licences never mention the maintenance you absorb.
This guide explains what cloud software is, where it genuinely wins, where it genuinely loses, what it costs over time, and how to decide for your own business rather than by fashion.
What is cloud software?
Cloud software runs on servers owned by a provider and reaches you over the internet, usually through a browser. You do not install it, patch it, or size the hardware. You rent access, normally per user per month, and the provider handles the machinery underneath.
The formal definition still worth reading is the NIST definition of cloud computing, which sets out five characteristics including on demand self service and measured usage. It is four pages long and clearer than most vendor documentation written since.
How is it different from installed software?
Installed software gives you a copy you control on hardware you own. Cloud software gives you access to a copy the vendor controls and updates for everyone at once. The difference shows up most sharply when something goes wrong, because your options narrow to what the vendor allows.
| Dimension | Cloud software | Installed software |
|---|---|---|
| Upfront cost | Low, often none | High licence fee |
| Ongoing cost | Continuous, rises with headcount | Optional support contract |
| Updates | Automatic, not optional | Your schedule, your risk |
| Access | Anywhere with a connection | Wherever the machine sits |
| Data location | Vendor decides, within limits | You decide |
| Customisation | Configuration only | Deep, if you have the skills |
| Failure mode | You wait for the vendor | You fix it, or nobody does |
| Exit | Export and hope it is complete | Keep running the old version |
That last row is the one people discover too late. A perpetual licence keeps working after a dispute. A subscription stops. For a fuller comparison see SaaS versus traditional software.
What are the real advantages?
Three advantages hold up under scrutiny. You stop maintaining infrastructure. You get security patches without deciding to install them. You can add or remove users in minutes instead of procurement cycles. Everything else on the average sales slide is a restatement of these three.
The patching benefit is underrated. Most breaches of self hosted systems exploit flaws that were fixed months earlier by a patch nobody applied. Handing that job to a provider with a dedicated team is a genuine security upgrade, as covered in SaaS security.
Speed of change matters too. Adding fifteen seats for a seasonal push takes a few clicks. Doing the same with installed software means licences, hardware and a week of somebody’s attention.
Where does cloud software genuinely lose?
It loses on long horizon cost, on deep customisation, on offline work, and on control of timing. If your process is unusual and stable, a configured cloud product will fight you for years. If your connection is unreliable, browser based tools stop being tools at all.
- Forced updates. The interface changes on the vendor timetable, sometimes during your busiest week.
- Price escalation. Renewal increases arrive once you are dependent, and switching cost is your negotiating weakness.
- Feature removal. Vendors retire features you rely on, and you have no version to stay on.
- Integration limits. You can only connect what the interface exposes, not what the database contains.
When those limits bite hard enough, firms build their own. That is when custom web development starts to make financial sense rather than emotional sense.
What does cloud software cost over five years?
More than the monthly figure suggests, and usually more than a perpetual licence. A tool at 40 dollars per user per month across 20 users costs 9,600 dollars a year, or 48,000 dollars over five years before any price rise. That comparison is rarely put on a slide.
Cloud still often wins, because the alternative includes servers, backup, patching time and the person who does it. The honest calculation includes those. Build the five year model with headcount growth and an annual increase of five to eight percent, which reflects recent vendor behaviour rather than optimism. Pricing structures vary widely, and how SaaS pricing works covers the common models.
Who owns your data in the cloud?
You own it in almost every reputable contract. Ownership is not the useful question. Access is. What matters is whether you can export everything in a usable format, how long the vendor keeps data after cancellation, and which subprocessors touch it along the way.
In Europe and the United Kingdom the relationship is governed by processor obligations set out in Article 28 of the GDPR, which requires a written contract covering exactly these points. Test the export while you are still a paying customer. An export that omits attachments and history is a common and unpleasant discovery.
What happens when the vendor goes down?
You wait. That is the whole answer, and it deserves to be stated bluntly before you sign. Published availability targets of 99.9 percent still allow around 43 minutes of downtime each month, and service credits refund a fraction of your subscription rather than your lost trading.
Plan for it rather than resent it. Keep an offline copy of the records you need to trade, know the status page address before you need it, and decide in advance what your team does during an outage. The mechanics are covered in what SaaS uptime really means and how providers handle downtime.
What types of cloud software exist?
Three layers, from most managed to least. Software as a service gives you a finished application. Platform as a service gives you somewhere to run your own code without managing servers. Infrastructure as a service gives you raw machines and leaves the rest to you.
Most businesses only buy the first. Development teams use all three. The layer underneath your applications is described in SaaS infrastructure, and the shared architecture that makes the economics work is explained in multi-tenant software.
How do you decide for your own business?
Answer four questions honestly. Is this process standard or genuinely unusual. Will headcount grow. Can you tolerate an outage you cannot fix. Do you have anyone who would competently maintain the alternative. Three cloud answers out of four means buy the subscription.
The pattern we see most often is sensible. Standard functions such as email, accounting and support go to the cloud, because your version of those is not special. The one process that genuinely differentiates the business gets built and owned, as in our Orbit multitenant platform work. Renting your commodity and owning your edge is a defensible strategy. Renting everything is a decision made by nobody in particular.

Frequently asked questions
Is cloud software the same thing as SaaS?
Not quite. SaaS is one layer of cloud software, the finished application you log into. Cloud software also covers platform services for running your own code and infrastructure services that rent you raw servers. Every SaaS product is cloud software, but not every cloud service is SaaS.
Is cloud software cheaper than buying a licence?
Cheaper to start, often more expensive across five years. Model the full period including headcount growth and annual increases of five to eight percent. Then add what you would otherwise spend on servers, backups and the person maintaining them. Cloud usually still wins, but by less than the sales pitch suggests.
What happens to our data if we stop paying?
Most vendors keep it accessible for a grace period of 30 to 90 days, then delete it. Check the exact window in your contract, because it varies more than people expect. Export a full copy before you cancel, and confirm the export includes attachments, history and any custom fields.
Can cloud software work without an internet connection?
Some products cache data for limited offline use, but most stop working. If your team works in places with unreliable connectivity, test that scenario during the trial rather than trusting the feature list. Offline support is one of the most commonly overstated capabilities in the category.
Is our data safe with a cloud provider?
The infrastructure is usually safer than what a small business can run. The risk shifts to your configuration, your user accounts and the third party apps you connect. Providers secure the platform and you secure the way it is used, which is where most incidents actually begin.
When should a business avoid cloud software?
When the process is genuinely unusual and stable, when regulation fixes where data may live, when connectivity is unreliable, or when you need control over exactly what changes and when. Those four cases are less common than people claim, but they are real and worth checking.
