Let your competitors eat the cost of IE6 dev then Always charge as LEAST as much as is required to make you either not care or actively want the client to buy a feature So if IE6 makes the site 2x as difficult, charge them for the site using modern browsers, and line item (basic IE6 testing for at least limited functionality) at whatever price makes you not care. Charge for them to maintain an outdated site, charge a lot. Then you won't care if they want IE6 support or not
