Custom Software vs SaaS
Custom Software vs SaaS: Which Costs Less Over Five Years?
Custom software vs SaaS is really a question about time. One bill ends. The other never does, and it rarely stays flat.
Free, no obligation, and no sales sequence afterwards.
The Rent Never Stops
A subscription looks cheap in month one. Then your team grows, so you add seats. Later your data grows, so you cross a record cap. Eventually a feature you use moves up a tier.
None of that is unusual. Airtable changed what its plans included in 2023, and paying customers absorbed it. Knack raised prices twice in about a year. Vendors are allowed to do this, because it is their software.
Custom Software vs SaaS, Side by Side
| Rented platform | Software you own | |
|---|---|---|
| Cost shape | Monthly, rising | One build, then upkeep |
| Users | Often per seat | Unlimited |
| Records | Capped by tier | Your database, your limits |
| Feature set | Vendor decides | You decide |
| Exit | Migration project | You already have the code |
Run Your Own Numbers
Take your current monthly bill. Multiply by sixty. Then add the seats you expect to add, plus the tier jump waiting at your next record cap.
That figure is your five year rent. Compare it against a fixed build cost plus modest upkeep. Sometimes rent still wins, and we will say so.
Where Rented Tools Genuinely Win
Speed to start, obviously. Also templates, mobile apps, and a support team you did not have to hire.
If your needs are simple and your team is small, stay put. A free tier beats a build every time at that size. The case for owning gets strong once you hit occasional users, big record counts, or client portals.
The Risk Nobody Prices In
Vendors change hands. Podio moved from Citrix to Progress. In August 2026 Bending Spoons agreed to acquire Airtable, and that deal has not closed yet.
Nothing has changed for Airtable customers so far. Still, the point stands: your roadmap belongs to someone else. Owning your code removes that variable entirely.
Questions
Common Questions
If I pay for custom software, do I own it?
Only if the contract says so in writing. This is the most expensive misunderstanding in software contracts, and it catches experienced buyers. Under US copyright law the author owns the work, and for software the author is whoever wrote the code. Paying an invoice does not move that. Ownership transfers through an express written assignment and nothing else. Without one, you may hold only an implied licence to use what you paid to build.
Does a work for hire clause cover it?
Usually not, and that is the trap. Work made for hire is narrow. It covers employees acting within their job, and beyond that it covers only nine specific categories the statute lists, such as translations, compilations, and contributions to collective works. Commissioned software often fits none of them. So a contract can say work for hire, mean it sincerely, and still leave the copyright with the developer. Ask for an assignment clause instead.
What is the difference between source code access and ownership?
Access lets you read it. Ownership lets you act. A contract can hand you a copy of the source and still keep the rights, which means you cannot legally modify it, hire someone else to work on it, or deploy it where you like. Ownership means you can do all three, and keep using it if the relationship ends. Ask which one you are being sold, because the words are often used interchangeably.
Is custom software slower than buying a subscription?
At the start, yes, and the honest comparison is not day one. A subscription runs this afternoon. A build ships in stages over weeks. What changes is the direction of travel: the subscription gets more expensive and more constrained as you grow, while the build is finished and yours. See how the build process works for the stage by stage timeline.
What if you disappear?
You keep everything, and there is a test that proves it. Hand your repository and setup documentation to a developer who did not build the app, and ask them to run it locally. If they succeed without calling us, the handover is real. If they need us, it was never a handover. Run that test at the end of any build, with any vendor, including this one.
Do I have to replace everything at once?
No, and usually you should not. Most tools are not all bad. One workflow is miserable and the rest is fine, in which case a Chrome extension can fix the painful part and leave the platform alone. Full rebuilds make sense when the platform itself is the constraint. That is most often Knack, Airtable, or Smartsheet.
