Early in the game, a "business investment" can be something as simple as a few spiral notebooks and pens to keep track of notes and conversations with clients. One investment in my business that I wish I had made much sooner was a wireless laser printer. The one I have is a Brother HL-2270DW. It doesn't do color, and graphics aren't its long suit, but it's perfect for printing out research materials. Mine cost just over $100, and you can get store brand toner cartridges for around $20. Before I had this printer, I used an inkjet printer, and always felt like I was wasting ink, no matter how useful a printed copy of material was to my work. Those worries are all but gone with this printer. There's no telling how much I would have spent on ink over the last year had I stuck with the inkjet printer. Like I said, this isn't the printer for those who need good graphics or color, but for researchers who need to print out text, it's perfect. You can set it to 300 dpi and automatic duplex to keep toner and paper consumption to a minimum. And I've had no trouble whatsoever with the wireless connection, even though the printer is in another part of the house than my office.
I'll be honest: the first couple of years I was doing this, spending $100 on a printer would have felt like the pinnacle of frivolous consumption. But between the money I've saved on ink cartridges and the lack of stress over printing out necessary research materials that I can annotate and mark up, it has been one of the best investments I've made in my business.
