Hi Ricardo,
We use RMS POS (Windows Dynamics) solution (just the POS) to process point of sale transactions, and integrate to Adagio with Link2POS.
It is a standalone multiuser POS with automated Adagio integration showing all customers, customer pricing, inventory items, and replicates pricing and taxation of Adagio Order Entry, and allows you to process payments on invoiced sales from Adagio Order Entry, POS, or payments on customer accounts.
What it doesn't do is (as Doug has noted), is link to a popup for a credit card processor, to complete the credit card payment within OE invoicing. You can complete the OE sales invoice and then pay for it in RMS POS. The payment entry simply scans the bar code of the Adagio Invoice and applies the payment with, single or multiple tenders. We have a number of high volume Adagio sites using in both USA and Canada.
Please feel free to contact us for details at 800-540-3164 or your Adagio dealer for details.
Best,
Brian
