What questions should be asked when ordering a service?

Question

Law in IT

Good evening!
I am placing an order for a service. A fairly large project, mobile applications will also be implemented. The provider is responsible for developing and maintaining the service.
I wanted to discuss what issues need to be raised to the performers (excluding technical issues)?
1. Guarantees after service development and bug fixes in the system. Guarantee period.
2. The cost of maintaining the system
3. Note in the contract that the contractor will not develop competing projects (prohibition to develop similar services for this topic) for a period of 5 years.
The theme of the project is consultation of individuals on taxes and assistance in preparing documents (but the system itself is unique - Multifunctional Portal).
The development cost is about 1.5 million rubles only for the service itself.

Answer 1

IMHO:
1) Hardly any guarantees can be. There is a development contract. There is TK. There is a final check. Bugs are corrected according to the TOR. Wishlist is added according to the price list. Bugs after the acceptance of the act on the work done is already your headache (you can agree on some critical errors, but in theory they should be revealed at the acceptance stage). The most pleasant option - you pay for the correction of errors to the same employee on his usual terms.
2) It all depends on the meaning invested in the "maintenance of the system." Every day for 12 hours to edit something is one thing. Checking everything once a month for an hour is another thing.
3) If your project is just code and quite simple, then all your prohibitions are... Meaningless. You have to invest something of your own in this service. Those. a developer, even with a complete codebase, should not be able to launch the project. And the meaning is not in the code, something of its own, but something other than an IT project: connections, agreements, a source of content, something else.
Well, it would be nice to give figures about the project: approximate amounts, in what area, what complexity?
