Using T-Rex, you can prepare your bulk transactions off-line and then upload them to the T-Rex Server. The T-Rex Server then enters the transactions on your behalf and sends you a detailed e-mail with status when the batch is completed.
Transactions supported include single and double-sided bookkeeping entries (BK1, BK2), trades (PS1, CROSS) as well as tax (RAJ, BKW) and stock record transactions (SR1).
