POS interface for qb

Job ID: 31499421

Budget: $250 – $750 USD

Need to develop basic web based POS with QuickBooks Desktop app CRM for:
- Invoicing
- Credit Notes
- Refunds on the credit notes/invoices
- Customer Record
- Payment on invoice
- Payment

Primary Interface is web based with multi-language support (which can be added later as well), the CRM is Quickbooks (any edition) like standard, pro or enterprise.
Quickbooks already supports and provides APIs for the required functions.

Web should support scaling to all devices (desktop, mobile, tab).

Need xml based interfacing so can be further interfaced with other solutions if need be.
