We've been asked to undertake a review of the Accounts and other financial documents of a small company, by the person who is interested in buying it. Until their contact with us, we didn't know this person and have only spoken to them by phone,
In the past we would peform such work, issue the report to the person, and then send the invoice to them for payment: the risk being that they would have the report but wouldn't pay us. These jobs are typically less than £500 ones.
Just wondered what others do? Would you charge in advance of undertaking the work (so protecting the hours it takes to do it), or do the work but not release the report until they've paid, or take a deposit for example?
