Sage Online Tools - Biggest mistake to let them create our online ordering site!!

We chose Sage Online Tools to create our e-commerce online ordering website, as we thought: 1. Sage/Pastel is a well know brand 2. We use Pastel as our accounting package , so it would sync with our system and avoid double work. WORST decision we ever made!! The online ordering site is so limited with functions, you cant use zapper or any new payment methods. You cant use coupons or special discount codes, you cant automate e-mail responses, you cant create specials, you cant, you cant, you cant... Then they create the site and after it has been created, when it does not want to sync with pastel, to update the orders, update stock, then they say it is not compatible with our system...something they should have checked from the start. The online site, if out of stock, you can keep on pressing 1, over and over and a clients can order 1000 units of an item you only have 1 in stock and you will need to explain afterwards. Everything is so basic, you cant up-sell, it does not use AI, it cant promote, you have a basic ordering system that is in line with something of 15 years ago. Client registers an account and it does not keep record of their orders, who needs that, they ask? Every time you want to arrange your delivery, you have to re-enter your province, it cant store it and if you don't enter it, your province shows -1. Asking to have it compulsory to complete or store the info, is not possible, as the UK has to approve and design and develop... So for all business out there, thinking of using Sage for your online ordering site, PLEASE don't, it is terrible and their customer service is always with excuses that are not solvable of your fault. I don't know how they still do business, it is shocking!!!
