The most critical problem here is invoices and contracts, not behind.
If the other party is not requested by regular invoices and qualified companies, he only finds such a company, through them. In general, the routine is a 10% commission that the company, the tax paid by the invoice. In fact, this approach is not very suitable.
Copyright Generally, to see if the other party is required, this can be used as a basis for the improvement price. If the project itself is simple, the development cost does not exceed 60% of the investment amount (can change), the other party can request copyright. After all, business processes and information are provided by each other.
Because I don't know what I want to develop, I don't say how to control costs here. In short, the project is not very large, as much as possible reduces all unnecessary troubles and procedures, do not plan, directly develop, guide users through the interface, then go out, and then modify while doing.
Acceptance generally depends on the requirements of the user, this must be controlled, and the contract must be written so that the two sides can have a determined content.
The first payment requirements should be higher, at least more than 80% of your development costs, then, after the arrival is installed, it will receive the second payment. If the second pay is not in place, it refuses to continue the revision, the reason is very understand. Otherwise, you may never get the second payment. In short, all things must be clear to the paper, the relationship is good, and must do this, otherwise, both parties may really go.
Be cautious, cautious!
