Heres a useful site for IT people in schools.
If you answer yes to any of these questions, then I would consider schoolquote.
1. Do you need to produce 3 quotations to your senior managers before the order being accepted.
2. Do you need written quotations of items sent via email before you place any orders.
If you answer is yes to one or both of these, then I would consider using schoolquote.co.uk.
Schoolquote allows you to get quotations for projects, hardware, software even furniture!!! and it allows you to state all your requirements, if you know what you want you can give them model numbers etc and then reputable companies who are registered as a supplier with schoolquote will then come back to you with a written quotation via the site.
The good thing about this is that schoolquote don't disclose any details to the supplier of who has asked for a quote, its completely anonymous.
Can be very useful when you looking to get quotations quickly and don't have time to contact all your regular suppliers You could even use it to get an idea on pricing and then what ever the cheaper price is you can go back to an account manager that you trust and place an order with your regular suppliers.
It be good to hear others feedback on this. Members who are already with schoolquote if you could provide positive or negative feedback that would be great.
BTW its free to signup.
