I'm a bit confused by one of the conditions in the contract which I've just been offered. According to one paragraph I agree to reimburse the agency for all reasonable expenses occurred on my behalf (anything over a certain amount has to be authorized by me in advance). What worries me is that the contract states I have to pay these expenses within two weeks of receipt of an invoice, or at the agent's sole option, these expenses might be deducted from the proceeds of the novel's sale. Is that normal? I don't much like the idea of getting a bill (for $295.00, worst case scenario) if the novel hasn't even sold yet.
