If you’ve priced out custom packing slips before, you’ve probably noticed the range is huge — a few cents a sheet for plain stock you print in-house, versus fifteen to twenty cents a set for carbonless multi-part forms shipped straight from a print shop. The right answer depends on what the slip actually needs to do: sit in a box as a receipt, or travel with the order as a signed proof of delivery, return authorization, or internal copy.
This guide walks through the two main formats businesses order, what they actually cost at real quantities, what sizes and stocks are available, and how long you should expect to wait once you hit “place order.” The goal is to get you from “I need packing slips” to a spec sheet you can hand to a printer with confidence.
Single-part vs. carbonless: which custom packing slip do you actually need
Most sellers default to a single-part packing slip: a plain or lightly branded sheet that your shipping software (ShipStation, Shopify, Shippo) generates and your laser or inkjet printer outputs on demand. There’s no minimum order and no lead time, because you’re not pre-printing anything — you’re printing a template onto blank or custom letterhead stock as each order ships. This is the right call if your packing slip only needs to exist once, inside the box.
Carbonless NCR forms are a different product entirely. These are pre-printed, multi-copy sets — usually 2-part or 3-part — where writing or printing on the top sheet transfers to the copies underneath via a chemical coating instead of actual carbon paper. Businesses order these when the packing slip needs to produce a second or third copy on the spot: one copy ships with the order, one stays in a driver’s or warehouse log, one goes to accounting. If you run wholesale, B2B, or will-call orders where someone hand-writes adjustments at the point of pickup, this is the format that makes sense — and it’s ordered in bulk ahead of time, not printed per-order.
What custom packing slips actually cost
Pricing on custom packing slips scales the way most print jobs do: a steep per-unit drop as volume increases, then diminishing returns past a few thousand units. The clearest real-world numbers come from carbonless form pricing, since that’s a fixed, pre-printed product with published tiers rather than a per-sheet office-printing cost that varies by printer and toner.
Single-part stock: the cheaper default
If you’re printing on demand, custom letterhead-style packing slip paper runs a few cents per sheet even before ink — the paper stock itself is the main cost, not the printing, since you’re doing that in-house at ship time. This is why most direct-to-consumer sellers use single-part stock: there’s no bulk order to plan around, no minimum, and no risk of sitting on 5,000 forms with an outdated logo.
Why 3-part forms cost what they do
The jump from single-part to multi-part isn’t really about the printing — it’s the carbonless paper itself (which costs more per sheet than plain bond) plus the collating and gluing step that binds the sets together. That’s also why these forms are sold in fixed lot sizes rather than “however many you want.”
Sizes and paper stock options
8.5″ x 11″ full sheet is the standard size for custom packing slips, and it’s what most shipping software defaults to. It gives you room for a full itemized order, return instructions, and branding without anything getting cut off.
Half-sheet (8.5″ x 5.5″) formats exist mainly for combined label-and-slip printing — the shipping label occupies the top half of the page, the packing slip content sits below, and you tear or fold the sheet before inserting it. It saves paper and a print pass, but it’s a tighter layout: orders with eight or more line items tend to get squeezed or truncated, so it works best for stores that ship simple, low-SKU orders.
On stock, plain 20lb bond is standard for single-part slips; carbonless sets come in white, canary, and pink sheet combinations, with the extra colors serving as the retained copies. If you want your packing slip to double as a light piece of brand collateral, ask your printer about a lightly coated or heavier stock for the top (visible) sheet — it won’t change the format, just how it feels in hand.
Lead times: what to plan around
This is where the two formats diverge most in practice. Single-part packing slips have effectively zero lead time because you’re printing them yourself as orders come in — the only constraint is your own printer and paper supply.
Carbonless multi-part forms are a different story, because they’re a manufactured product with a collating step. Standard production runs about 5–7 business days once art is approved. Budget accordingly, and if you’re a growing operation, order your next batch before you’re down to your last box — running out mid-week and needing a rush job is the most expensive way to buy these.
What to put on the slip
Whichever format you choose, the content is the same job: tell the recipient what’s in the box and what to do if something’s wrong. At minimum, include the order number, itemized SKUs and quantities, the ship-to and bill-to (if different), and a returns or contact line. If you’re using a 3-part form for wholesale or will-call, leave a signature line and a blank field on the retained copy for internal notes — that’s the whole reason to pay more for the multi-part format, so don’t skip it.
Keep branding restrained on the printed area itself if you’re using single-part stock through a laser printer: heavy color fills print unevenly and slowly on most office equipment. A logo, a single accent color, and clean typography read better than a full-bleed design that your printer chokes on.
How to place the order
For single-part stock, most printers just need your template (PDF or the built-in ShipStation/Shopify template) and a stock selection — there’s no proof-and-collate step, so turnaround is closer to standard document printing. For carbonless forms, expect a proof step before your order goes into production, since errors are far more expensive to fix after 1,000 sets are collated and glued than before. Confirm sheet colors, numbering (sequential form numbers are a common add-on for audit trails), and perforation if you want the copies to tear apart cleanly. Get the proof signed off in writing before it goes to press — a $150 order isn’t worth reprinting over a typo, but it’s also not free to redo.
Frequently asked questions
What’s the minimum order for custom packing slips?
Single-part stock you print yourself has no meaningful minimum — you’re buying blank or lightly branded paper and printing on demand. Pre-printed carbonless (NCR) forms are typically sold starting at 250 sets, with common break points at 500, 1000, 2500, and 5000.
How much do custom packing slips cost per unit?
For 3-part carbonless forms, expect roughly $0.15–$0.19 per set depending on volume, based on current published pricing for 250–1000 unit orders. Single-part stock is cheaper per sheet but you’re paying for printer ink and paper separately rather than a finished, pre-printed product.
Do I need carbonless (NCR) forms or can I just print a regular packing slip?
If the slip only needs to travel with the order once, a regular single-part sheet printed from your shipping software is simpler and cheaper. Choose carbonless multi-part forms only if you need a physical duplicate copy created at the point of writing or printing — common for wholesale, will-call, or driver-signed deliveries.
What size should a custom packing slip be?
8.5″ x 11″ full sheet is standard and gives the most room for itemized orders. Half-sheet (8.5″ x 5.5″) works for simple, low-line-item orders where the slip is combined with the shipping label on one page.
How long does it take to get custom packing slips printed?
Standard production on pre-printed carbonless forms runs about 5–7 business days. Single-part stock has no production lead time since you print it yourself as orders ship. Rush service, where offered, can bring carbonless form turnaround down to 24–48 hours for an added fee.
Can I add sequential numbering to packing slip forms?
Yes — sequential numbering is a common add-on for carbonless multi-part forms and is useful if you need an audit trail for wholesale or will-call transactions. Ask your printer to include it during the proofing step, since it has to be set up before the print run, not after.
The bottom line
The decision on custom packing slips usually comes down to one question: does this slip need to make a second copy on the spot? If not, single-part stock printed through your shipping software is cheaper and has zero lead time. If it does — wholesale accounts, will-call pickups, driver sign-offs — budget for a 3-part carbonless form, order in one of the standard lot sizes, and build in the 5–7 day production window so a routine reorder never turns into a rush fee.
