Free Quote Gberator for business?

Enigmaman

I run a small business and some of my suppliers have recently sent me quotes with a button Inviting Me to "Accept Quote" and pay.

I would like to introduce this as it seems a very neat way of encouraging customers to pay upfront.

Does anyone have any recommendations for apps/websites that can do this, preferably free ones?

Is it not clear who your suppliers are using?

Enigmaman

No, it isn't.

The two quotes concerned seem to be using some kind of custom-built form.

Then what they are doing may be a custom built solution... a link may provide some clues to what they are using but unless you intend to replatform your whole website or are happy using a link to Sage or similar accounting software then you are probably better off looking at plugins for your existing CMS
