Linking to legal documents in quotations

With the express purpose of making my documentation lighter, I was wondering if I were to put a link on my quote’s sign acceptance section to a page on my website spelling out my generic terms and conditions. The client signing the quotation would therefore be “accepting said terms and conditions”.

Would this be a strong enough legal bind to conduct business safely?

Does anyone have first hand knowledge of this method of spelling out the terms of engagement?

My main reason for this is that my current terms and conditions (on my single page quotation) include the following:

Terms & Conditions
By Acceptance of the Quotation and Invoicing Terms you agree to be bound by the following terms and conditions. Subject to change and alteration from time to time at the sole discretion of Allchorn Design.
Deposit
Where applicable you agree to deposit 50% of the quotation value into the account specified on the Quote prior to commencement of the project.
Validity
All quotations are valid for 14 days from the date of issue.
Termination
Should you decide to cancel the quotation prior to commencement of work, the deposit will be retained to cover expenses incurred and no refunds will be made. Should you decide to cancel after the work has been completed you will be liable for the remainder of the quotation amount on completion.
Payment Terms
Payment is strictly COD (cash on delivery). Unless other terms have been priorly negotiated and issued in writing by Allchorn Design Management.
Late or non-payment
Allchorn Design reserves the right to charge interest on late payments at the prime interest rate of South Africa + 5% compounded on a monthly basis.
Timely Delay
Should the client for any reason delay the supply of information necessary for completion of the work, as accepted in the quotation, for a period exceeding 60 days the client will be invoiced in full for work completed to that date. We reserve the right to adjust our standard terms and agreements from time to time.

I would like to include aspects like that the purchase of stock imagery for use in any designs will be charged at cost + 10% handling fee, hosting is a separate cost with their hosting provider and other factors that clients assume will be included, but infact aren’t unless quoted for (copywriting, photography, illustration etc.)

It might be very useful to do that. However, it would be very hard to prove that the client clicked on, read, and understood the terms. So, it could be a bit risky if there were a dispute because the other party could claim that no contract was made because they were aware of all the terms, etc. In order for a contract to be enforceable, you need the other party to have been informed of and completely understood the terms of the contract. So, you need to make it easy and simple for them to do that.

IANAL but I assume there is a reason that whenever I sign a contract they make me initial each page individually and sign at the end.

To prove that I saw every page and had the opportunity to read each one of them.

If you just reference another page, how do you prove that they read it? Or what was actually on the page at the time of reading?
