If Feb. is closed, create a vendor credit for each invoice and enter the same Category/Item details on the vendor credit that are on the invoices. Then, apply the vendor credits to the invoices. If Feb. isn't closed (or you're a small business that doesn't have a formal close), you can delete the invoices. If you create vendor credits and apply them, your P&L will show the expenses in Feb. and a reduction in those expenses in Apr. If you delete them, the expenses on Feb.'s P&L will be reduced.
