XKDOUS Invoice Book, 2-Part Carbonless, 5-9/16 x 8-7/16 In

The Verdict

Let’s be direct: for $5.99, you’re not buying a luxury invoicing system. You’re buying a stack of numbered paper that needs to work when a customer asks for a receipt. The XKDOUS 2-Part Carbonless Invoice Book does exactly that — and does it well enough to earn a 4.8-star average from 240 buyers.

What You Actually Get

The book measures 5-9/16" x 8-7/16" — noticeably more compact than standard 8.5" x 11" invoice pads. That’s the point. It’s sized for field work: contractors, mobile service providers, flea market vendors, anyone who doesn’t want a briefcase just to write a receipt.

Each set includes a white original and a yellow duplicate. The pages are carbonless — no interleaved carbon sheets to smudge or misalign. You write once, and the pressure transfers the copy. The book comes with 50 numbered sets, so tracking invoice numbers is automatic. A heavy chipboard backing gives you a solid writing surface when you’re working without a desk.

Real-World Performance

The carbonless transfer is the critical test, and it passes. As one reviewer put it: “The copy comes through clean and dark — none of that faint, barely-readable junk you get with cheap receipt books.” That matches the general sentiment across the 240 ratings. The numbered pages are a small feature that saves real headache when you’re reconciling at end of month.

The size is the other winner. Multiple buyers mention keeping it in their car or service van. One landscaper noted: “Fits in my glove compartment with room to spare. I can write a receipt leaning on the hood if I have to.”

Where It Falls Short

The thinness of the paper is the most common complaint. Not that it tears easily during normal use — but if you press hard, the impression can ghost through to the next unused set. Minor, but worth knowing.

The bigger issue: 50 sets goes fast. If you’re writing more than two or three invoices a day, you’ll be reordering monthly. At this price, that’s manageable, but it’s not a bulk solution. You’re paying for convenience, not volume.

Also worth noting: there’s no carbonless “customer copy” option for a third party. It’s strictly two-part — fine for most small operations, but if you need a second internal copy, look elsewhere.

Who Should Buy This

• Solo service providers (plumbers, electricians, cleaners) who need a quick, professional receipt on-site
• Market and event vendors who write occasional receipts and don’t want to lug around a full-size invoice pad
• Anyone who needs a backup when a phone-based invoicing app fails or the battery dies

FAQ

Q: Does the yellow copy stay legible over time? A: Carbonless copies don’t fade like thermal paper. Store the book closed and the duplicates will hold up for years. They’re not archival quality, but they’ll survive tax season.

Q: Can I run these through a printer? A: No. This is a manual-write book. The paper is not designed for inkjet or laser printing — you’ll get smears and jams.

Q: Is there a place to write a PO number or terms? A: Yes, the layout includes fields for date, invoice number, customer info, item descriptions, quantity, and total. It’s a standard layout — nothing fancy, but functional.

The Verdict

Buy it if you need a compact, reliable, no-fuss receipt solution for on-the-go work and you don’t want to spend more than a fast-food lunch. The carbonless transfer is clean, the numbering saves you bookkeeping headaches, and the size genuinely fits where you need it.

Skip it if you’re writing high volumes daily, need three-part copies, or require something that feeds through a printer. For those cases, spend more on a heavier-duty system.

Rating: 4.6/5 — a small tool that does exactly what it promises, at a price that makes the minor flaws easy to forgive.
