Paying invoices

Good night,

I have a listing in Jamaica W.I  but I live in the U.S. Booking.com does not offer Jamaicans a convenient way to pay. I received an invoice for a small amount. On the invoice it says wire amount to a U.S. based bank of America with account number and other details. I tried wiring which could work but the cost of wiring $50 is $25  on to of the $50 invoice. Seems bonkers to me. So I canceled that. I then discovered I can put in the same info as a bill pay from my bank account. I did that and added the accommodation number and invoice number in the memo. The money has left my account and has been deposited but to date my invoice says unpaid on booking.com.
