Adjust billing on a layout project?


Hey, Typophiles! Turning to you for advice: I bill by the project, and have just finished laying out a report that I billed at 2.25 days. Only problem is that (for once!) I overestimated how long it would take – I really worked about 1.5 "days" on the project, including admin.

My question: do I follow-up once the project closes and adjust my fee downward, making clear the reason? Or do I take the money and run, since we all agreed on the scope and the rate in advance?

What to do? Client wants me to use a font I don't have, but I can't bill for it and buying it negates the profit.

I picked up a client that uses Optima as their standard face. Despite it's ubiquity, I don't actually own Optima. It's a small email blast, so billing for the font would send the client elsewhere. Likewise, purchasing the Optima family would negate my profits.

Is there an ethical and legal solution here that still lets me make money on the project?

Can I obtain and use Optima for free (like a printer does) for use solely on this project because the client has already purchased it?

Any ideas out there?
