Frequently Asked Questions

There are three options which you can choose from:
  • Fixed-price fixed-scope model: If you have well-defined requirements and a pre-decided timeline for your project in mind, a fixed-cost model would work best for you.
  • Time-and-materials model: If you are unable to decide on a fixed scope, timeframe, or cost for your project, you can go for this model. Your project can be divided into smaller phases over time, incurring controlled costs.
