We don't start work without contract and annex signed.
If you're a new client (we haven't received payments from you before) we start work only after prepayment.
An account manager is responsible for the kick-off.
An account manager is responsible for telling client that works can be started only after docs signed.
A partner can take responsibility for starting works without documents signed. In that case, hours won't be reimbursed if the client cancels the collaboration.
We have only two types of contract: Dedicated Team and T&M.
If you need an estimate we can do it in 3 ways:
Free estimate if the project is small (<= 1 month)
Technical Discovery workshop (if you have complete prototype and requirements) - 8h (solution architect)
Design Thinking workshop (if you don't have complete prototype and requirements) - 16h (designer, solution architect)
