I know what it means. I've seen delta-V charts. But I don't know if Robert Heinlein wrote this down, or simply said it off-the-cuff to somebody.
Variations include:
"Reach low orbit, and your halfway ..." (See Space Access Society logo http://space-access.org)
"Make orbit, and you're halfway ..."
If we want to attribute this to him, a citable source would be handy.

Just for the record, it should be noted that Heinlein seemed to have a good understanding of orbital mechanics. Books he wrote as early as the 1940' describe maneuvers that sound reasonable, not the usual "shoot from earth to mars in a couple hours".

I don't know where, but it is true because if you escape elliptic gravity then it is so much cheaper to go anywhere you want. Any little thrust any direction is effective immediately.

This phrase was quoted by Jerry Pournelle in an article entitled "Halfway to Anywhere" first published in the Galaxy Magazine in the April 1974 Issue in his column "A Step Farther Out". This article was then collected with others into his book of the same name.
Here's the article's opening:
One of my rivals in the science-writing field usually begins his columns with a personal anecdote. Although I avoid slavish imitation, success is always worth copying. Anyway, the idea behind this column came from Robert Heinlein and he ought to get credit for it.
Mr. Heinlein and I were discussing the perils of template stories—interconnected stories that together present a future history. As readers may have suspected, many future histories begin with stories that weren't necessarily intended to fit together when they were written. Robert Heinlein's box came with The Man Who Sold the Moon. He wanted the first flight to the moon to use a direct Earth-to-moon craft, not one assembled in orbit—but the story had to follow Blowups Happen in the future history.
Unfortunately, in Blowups Happen a capability for orbiting large payloads had been developed. "Aha," I said. "I see your problem. If you can get a ship into orbit, you're halfway to the moon."
"No," Bob said. "If you can get your ship into orbit, you're halfway to anywhere."
He was very nearly right.
