A third-party logistics provider, or 3PL, is a company you pay to hold your stock in its warehouse, pick and pack each order that comes in, and hand it to a carrier. You keep the store, the marketing and the customer relationship. They keep the shelves, the tape and the labels.

It concerns anyone who ships physical products and has reached the point where packing boxes eats the hours that should go to selling. That point comes earlier than most people think, often somewhere between 100 and 300 orders a month.

What is third-party logistics (3PL)?

A 3PL is an outsourced warehouse plus an outsourced packing team plus negotiated carrier rates, sold as one service. You send them pallets or cartons of inventory. Their software connects to your store. When an order is paid, it appears on their screen, someone picks the items from a shelf, puts them in a box with your packing slip, prints a label, and the parcel leaves the same day or the next. Tracking flows back to your store and to the customer.

What a 3PL is not:

  • It is not a dropshipping supplier. With a 3PL, you own the stock. You bought it, it sits in their warehouse under your name, and you decide what to do with it.
  • It is not a carrier. UPS, DHL, USPS or La Poste move parcels. A 3PL prepares parcels and then hands them to those carriers, usually at rates better than you could get alone.
  • It is not a fulfillment marketplace program like the one Amazon runs for its own sellers. A 3PL is neutral. It ships orders from your own storefront, your link in bio, a marketplace, or all three.

Related vocabulary you will meet in quotes and contracts: receiving (checking in your inbound stock), pick and pack (the per-order labor), storage (rent per bin, shelf or pallet per month), kitting (bundling several SKUs into one sellable unit), returns processing, and SLA (the promised cut-off time, for example "orders received before 2 pm ship today").

Why it matters

Packing is invisible work. It never appears in your revenue chart, but it decides whether you have time to make content, answer customers and launch new products. It also decides your delivery speed, and delivery speed shapes reviews.

Take a concrete case. A ceramics brand ships 250 orders a month. Each order takes about 8 minutes to pack, label and drop at the post office, including the trips. That is 2,000 minutes, or 33 hours a month. At even $20 an hour of the founder's time, packing costs $660 a month before a single box or label is bought. Their own carrier rate averages $7.90 per parcel.

A regional 3PL quotes them $2.60 per order for pick and pack, $0.40 per extra item, $35 a month for storage, and a negotiated carrier rate averaging $6.40. Monthly cost for 250 orders with 1.4 items on average: $650 pick and pack, $35 storage, $1,600 shipping, total $2,285. Their old cost was $1,975 in postage plus $660 of labor, total $2,635. The 3PL is cheaper by $350 a month and gives back 33 hours. That is the usual shape of the decision, and it flips in favor of the 3PL sooner than intuition suggests.

The other side of the coin: at 40 orders a month, the same fees plus a minimum monthly charge of $250 would cost more than doing it yourself. Volume is what makes a 3PL pay.

How it works

The workflow from your side, step by step:

  • Send inventory. You ship cartons to the warehouse with a packing list. The 3PL counts and scans them in. Discrepancies are reported within a day or two.
  • Connect the store. The 3PL's software pulls paid orders from your store by API. Your SKUs must match theirs exactly, otherwise orders stall.
  • Orders flow automatically. Each paid order becomes a pick ticket. No manual export, no spreadsheet.
  • Pick, pack, ship. A worker collects the items, packs them with your inserts if you provided any, applies the label and hands the parcel to the carrier at the daily pickup.
  • Tracking comes back. The tracking number is written back to the order and the customer gets the shipping email from your store.
  • Stock syncs. The warehouse quantity is pushed back to your store so you never sell what is not on the shelf. Some 3PLs sync every 15 minutes, others once a day. Ask.
  • Returns. Returned parcels arrive at the warehouse, are inspected, and restocked or set aside according to rules you set.

You pay a monthly invoice with lines for storage, pick and pack, materials, shipping and any special projects such as relabeling.

Benchmarks and examples

Typical fee ranges seen by small brands in North America and Western Europe:

  • Pick and pack: $2 to $4 for the first item, $0.25 to $0.75 per additional item.
  • Storage: $0.50 to $1.50 per bin per month, $15 to $40 per pallet per month.
  • Receiving: $25 to $50 per hour or a flat $5 to $15 per carton.
  • Minimum monthly fee: $0 at small, hungry 3PLs, $250 to $500 at established ones.
  • Onboarding or setup: $0 to $500, sometimes waived.
  • Cut-off: orders before 12 pm to 3 pm ship the same day.

Situations where it makes sense:

  • A creator selling merch drops of 500 to 2,000 units a few times a year. A 3PL absorbs the spike without hiring friends for a weekend.
  • A skincare brand at 400 orders a month with 12 SKUs. Packing at home no longer fits in a flat.
  • A small store selling in two countries. A 3PL with a second warehouse abroad cuts shipping cost and delivery time for the second market.

Situations where it does not:

  • Fewer than roughly 100 orders a month with cheap, light products. The minimum fees eat the margin.
  • Products that are hand-finished or personalized at the moment of order. Most 3PLs will not engrave, embroider or mix.
  • Very fragile or oversized items where your own packing is a competitive advantage.

Common mistakes

  • Choosing on the pick fee alone. A $1.90 pick fee with a $400 minimum and $12 per carton receiving can cost more than a $2.80 pick fee with none of that. Model your real monthly bill with your real order count.
  • Sending stock without clean SKUs and barcodes. Every unlabeled unit gets relabeled at your expense, and mismatched SKUs mean orders sit unfulfilled.
  • Ignoring the stock sync frequency. If the warehouse syncs once a night and you launch at 6 pm, you can oversell for hours.
  • Forgetting returns. Ask what happens to a returned item, how much it costs to inspect, and how fast it goes back on the shelf.
  • Signing a 12-month contract at the start. Start month to month. If they are good, they will not need to lock you in.

Best practices

  • Calculate your all-in cost per order before and after. Include your own hours. Most founders undercount them by half.
  • Ask for a test month with 50 orders. You will learn more from 50 real parcels than from any sales deck.
  • Standardize packaging first. Two or three box sizes and one insert. Fewer decisions at the packing bench means fewer errors and lower material fees.
  • Keep inventory counts honest. Cycle count monthly. Compare the 3PL's numbers with your store's numbers and reconcile the gap.
  • Set clear rules for stockouts. Decide whether the 3PL should hold partial orders or ship what is available. Write it down.
  • Look at their carrier mix. A 3PL with three carriers can route each parcel to the cheapest option for that weight and zone. That alone can save 10 to 20 percent.
  • Keep a small reserve at home. For influencer sends, replacements and photo shoots. It avoids a $5 pick fee for a gift.

In Roctify

Roctify is not a 3PL and does not run warehouses. What it gives you is the clean order and product data a 3PL needs. Every paid order from your link in bio or your online store lands in one place with the customer's address, the items, their SKUs and the chosen shipping method. Stock lives in the shared catalog, so when you update quantities after a warehouse count, every channel shows the new number at once.

Practically, you export or connect your orders to the 3PL's system, ship stock to them, and keep selling. The 0% transaction fee on every plan matters here: when a 3PL already takes $3 per order, you do not want your platform taking another cut on top of the payment processor.

FAQ

At what order volume should I switch to a 3PL?

There is no single number, but most small sellers see the math turn positive between 100 and 300 orders a month, sooner if the products are bulky or the founder's time is worth a lot. Run the calculation with your real fee quotes and count your own hours honestly. If packing is what stops you from launching the next product, that is also a valid reason to switch earlier.

Do I lose control over the customer experience?

You lose direct control over the box but not over the experience. You choose the packaging, the inserts, the cut-off promises and the carriers. What you gain is consistency: a warehouse packs the same way on a Monday morning and on Black Friday, which a founder at their kitchen table does not.

Can I use a 3PL for only part of my catalog?

Yes, and it is a common setup. Send the fast-moving, standard items to the warehouse and keep personalized, fragile or slow items at home. Your store needs to know which products ship from where, so tag them clearly and make sure both locations report stock back to the same catalog.
