Most of this page is about when each model is the wrong choice, because that is the part nobody tells you and the part that costs money later.

Our engineers inside your team and your process.

Side by side
| Attribute | Fixed price | Dedicated team | Staff augmentation |
|---|---|---|---|
| Billing | Per milestone, against agreed deliverables. | Monthly, per allocated person. | Monthly, per person. |
| Commitment | The project. No ongoing obligation after handover. | Usually a minimum term, then rolling. | Usually a minimum term, then rolling. |
| Who carries the risk | We carry the estimate risk, so the price includes a buffer for it. That is the honest trade: certainty costs a margin. | You carry the scope risk and get the flexibility in return. Cheaper than fixed price when the scope really does move. | You own delivery and direction. We supply capability, not management. |
We have deliberately left rates and timelines off this page. Both depend on what you are building, and a number here that changes in the first call is worse than no number.
