Cost guide
The real cost of custom business software. And why the sticker price lies.
Custom software has a reputation for being expensive and slow. That reputation comes from how it was built, not from what it is worth. Here is the honest breakdown.

Why traditional custom software quotes balloon
A traditional agency quote starts at one number and ends at another. Discovery, design, build, revisions, and the inevitable change requests all stack on top of each other. By launch you have paid two to three times the original estimate, and you still owe for maintenance.
The reason is simple. Every line of code is written by hand, billed by the hour, and owned by the agency until they hand it over. The incentive is more hours, not a faster launch.
The new math
What a platform costs when AI does the heavy lifting
SpinFlow builds your platform with AI doing the repetitive work and a human team directing it. That collapses the timeline from months to weeks and removes the hourly billing trap entirely.
You pay a flat monthly subscription, typically one fifth to one tenth of what your current software stack costs. There is no surprise invoice, no change-request tax, and no separate maintenance contract.
Total cost of ownership
The number that actually matters
Upfront price is the wrong thing to compare. Total cost of ownership over three years tells the truth. Add up licenses, seats, integrations, the consultants who glue it together, and the time your team loses switching between tools.
A custom platform replaces that whole column with one line. Own the asset instead of renting a stack that gets more expensive every renewal.

Common questions
Questions about the cost
How much does a custom platform cost per month?
Pricing is custom because every business runs differently. Most clients land at one fifth to one tenth of their previous software stack cost, billed as a flat monthly subscription with unlimited seats.
Is there a large upfront fee?
No. The build is folded into the subscription. You are not paying tens of thousands before you see anything working.
What happens if I need changes after launch?
Changes are included. When a new requirement comes up, it usually ships the same week, not the next billing cycle.
Do I own the software?
Yes. Unlike most agency builds, the platform is your asset, not something you rent indefinitely from a vendor.
