No longer can we batch email invoices and have them paid on time. Noooo, now I get to generate our invoice, then log into the "portal", and re-enter everything in their invoice template. We have one customer for which we use this pile of crap, and were they not one of our bigger accounts, we'd dump them as a customer rather than use Tungsten. Entering an invoice takes longer, POs that I received a month ago aren't entered into the system when the job is complete and I go to invoice, so I have to manually type everything in. Some POs just never show up for me to accept, some show up right away, some show up eventually; it's like PO Roulette. The interface is kludgy, and even though I have *one* customer that forces me to use this, I still have to enter the shipping address *every time* because it's different from billing. I saved it in the address book, but every time, it doesn't fill in the state and complains that it's a required field. Best of all, we get the privilege of paying to send invoices. I'd always thought invoicing was where customers pay us for work we've done, but no; it's where we pay some random middleman company, and eventually, our customers pay us. Stay far, far away from Tungsten; it is the WORST.
