If you don't go through a tank a week, stick to using the jerry cans. If business picks up to run the equipment more, then the cost of purchasing an in bed tank makes it worth while. If for some reason business slows after you purchase the tank, you're out that much more money that you could've put toward related bills, etc.
I looked into getting a portable tank, i'm not sure what the DOT regs are in the US, but if you carry more than 100gallons you need TDG (transportation of dangerous goods) signs on the vehicle in question. With gasoline I go through maybe 75L a week for my equipment - small, I know. It only takes a minute to get the cans ready to fill and another minute to put them back.
On a positive side, when I had my snowmobiles it was a pita filling those up in -35C weather from small 2-3gal fuel cans. I know you mentioned you'd use the tank for diesel fuel, but there are also many ways to utilize a portable tank in the future. It's just questioning if the purchase price worth while, right now..
