All terms “Net 30” for companies or firms of which we are an approved W-9 submitted vendor.

Gateway Investigations works on a retainer basis for private citizens. After discussing your case in an initial free consultation, we will estimate the anticipated time and expense necessary to bring the investigation to a successful conclusion and set the retainer amount accordingly.

Payment may be made by cash, check, credit card or PayPal.

We will not exceed the estimated budget – or the amount of the initial retainer – without your prior approval.

At the conclusion of the case, we will issue you a detailed invoice itemizing all charges, and any remaining amount from the initial retainer will be refunded. Should you choose to cancel an investigation at any time, we will immediately refund all unused funds from the retainer.
