It sounds as though you've already looked at the job and discussed it with the property owner.

What I dont know is if I should seal the grout or not as we did not talk about it...
Did they not ask for a price then? If you have already priced the job, they may not look kindly on additional charges. But, since you didn't discusss sealing, you might be OK. Make sure you can explain the benefits of sealing the grout. Is it just office space that you'll be cleaning? If you have already priced the job I do think you missed your opportunity to sell color sealing as it is considerably more than using an impregnator.
My pricing for a commercial clean and clear seal is about $1.00/sqft. Depends on the size of the tile, the layout, and condition of the grout. I've been able to get around this price in offices and better commercial settings (like showrooms) but have not any luck with this pricing at places like Dunkin Donuts and Subway. (I've given what I consider rock-bottom prices and they still think it's too expensive. Yet if they call, they always seem to complain about the previous guy. They just don't get it!) Not sure exactly what you're dealing with but that's the comparison I can offer.
You have to be careful with discounting. There is no economy of scale with multiple locations if you need to travel, set up, and breakdown for every job.
