It's important to establish working conditions with the contractor beforehand. Most studios typically operate under the following format:
- Develop a technical specification (TS)
- Estimate the development cost
- Sign a contract with a fixed payment amount
Usually, this involves a 50% down payment before starting development, followed by the remaining payment after project completion.
At first glance, this seems straightforward, but this approach might not suit zero-to-one development projects. Not every client can accurately write their TS.
