Build vs. Buy
"Buy, don't build" was the right default when building was slow and expensive. AI changed the math. When the software is your operation — and you're paying per seat for it every year — building and owning it is often the cheaper, better call. Run the numbers below.
The calculator
Per-seat pricing scales with your headcount and climbs at renewal. A custom build is a fixed cost, and the software is yours to keep. Enter your numbers:
That's recurring, forever, and it grows with every hire and every renewal. A Slingr build is a scoped first phase and then one monthly tier, regardless of seats — and the code, data and specs we build are yours to keep. No seat meter, no renewal creep.

A straight answer
We're not anti-SaaS. We're anti-paying-rent-on-your-own-operation. Here's the honest line.
Email, payroll, expense reports, generic CRM for a small team — if it's not your differentiation and the off-the-shelf tool fits, rent it. Don't build what you can buy and forget.
The workflows that are your business — how you quote, produce, comply, serve — shouldn't be bent to fit someone else's template or held on their roadmap. Own them.
When you're paying per seat for software the whole company touches, the bill grows with headcount while the value doesn't. A flat, owned build breaks that curve.
If your data is siloed inside a vendor's platform and getting it out is a project, you don't own your operation — you rent access to it. Owning the software frees the data.
The reframe
AI-accelerated development ships custom software at a fraction of traditional cost and time — the old "building is too expensive" assumption no longer holds.
Per-seat pricing climbs every renewal, and AI features are increasingly billed per seat again. The rented option keeps getting pricier.
On a glide path — surround, substitute, sunset — you replace what you rent with what you own, without a big-bang cutover. See the full per-seat breakdown →
Questions buyers ask
It depends on scope and seat count, but the math has shifted: AI-accelerated development cuts build cost to a fraction of traditional cost, while per-seat SaaS compounds with headcount and renewals. For software the whole company uses, owning it is often cheaper over 3-5 years — run the calculator to compare your numbers.
Buy when it's a commodity that isn't your differentiation and the off-the-shelf tool fits well — email, payroll, generic tools. Build when the software is your actual operation, when per-seat pricing punishes your scale, or when your data is trapped in a vendor's platform.
It's yours to keep, but you don't have to staff it. Slingr can build it and then run it for you on a monthly tier, or hand it to your team with full documentation. Your call.
