Hello XXXXXXXX,
In trade transactions, a pro forma invoice is a document that states a commitment from the seller to sell goods to the buyer at specified prices and terms. It is used to declare the value of the trade. It is not a true invoice, because it is not used to record account receivable for the seller and accounts payable for the buyer.
Sales quotes are prepared in the form of a pro forma invoice which is different from a commercial invoice. It is used to create a sale and is sent in advance of the commercial invoice. The content of a pro forma invoice is almost identical to a commercial invoice and is usually considered a binding agreement although the price might change in advance of the final sale.
Unfortunately you might be locked into that error unless you can show that this was a clear error and does not normally occur in this deal or transaction. Of course if the contract agrees that it was an error then you will not be locked in and can change it. However if they relied on the error then you are locked in.
Please let me know if you have any other questions, or require clarification of this matter. Otherwise please hit "ACCEPT", so I may receive credit for my response. Thank you
