Does anyone have experience of salesorder.com?
I work with an Italian-owned food importer (£1.8m sales) who have been using Sage (line50) since 1992 (!) and wish to upgrade to an ERP system with stock accounting that copes with Landed Cost and is an integrated part of the double-entry system.
We are at the early stage of evaluation and wonder if anyone can warn us of potential pitfalls.
(We know Netsuite will cope with almost anything but the costs are high and the compulsory consultancy fees are heading in the direction of SAP consultants! Too expensive and probably user-unfriendly for a small company lacking an IT dept.)
Any comments are welcome.
Thanks
