The classic custom-software story goes like this. You scope a project, sign a fixed bid, and wait. Months pass. What ships is what you described at the start, which is never quite what you need by the end. Now every change is a new quote, a new negotiation, a new wait.
Why fixed-bid spirals
Fixed bids reward scope-locking, not outcomes. The incentive is to ship the contract and bill the extras. Speed drops as the codebase grows, because nothing was built to keep changing. Soon you're maintaining a thing nobody wants to touch, and the relationship turns adversarial.
What a subscription changes
A subscription flips the incentive. The provider only keeps you by shipping useful changes, month after month. There's no per-feature haggling because feature requests are unlimited, all part of one flat monthly price.
The result
You get a real platform in 2 weeks, then grow it forever, without the death spiral, the change-request backlog, or the six-figure surprise.
