How to Choose a 3PL: A Buyer's Checklist for Ecommerce Brands

Key Takeaways

  • Score 3PLs on five dimensions: pricing transparency, SLAs, integrations, location, and operational maturity.
  • Demand a written same-day cutoff time and a >99.5% order accuracy SLA — both should be in the contract, not the brochure.
  • Storage and pick-and-pack fees only tell half the story. Long-term storage, returns, and account-management fees are where margin leaks.
  • If a 3PL won't share a sample invoice from a similar brand, walk away.

What is a 3PL, and why does the choice matter?

A third-party logistics provider (3PL) receives your inventory, stores it, and picks, packs, and ships orders on your behalf. For an ecommerce brand doing more than a few hundred orders per month, the 3PL becomes the operational backbone of the business — slow shipping, broken integrations, or inventory errors will show up directly in your reviews, refund rate, and repeat-purchase numbers.

Switching 3PLs is painful: it typically takes 4–8 weeks, costs thousands in inbound freight, and risks a stockout during the transition. Choosing the right partner up front is one of the highest-leverage decisions an ecommerce operator makes.

How do you evaluate a 3PL? The five-dimension scorecard

Score every 3PL you talk to on the same five dimensions. If you don't, you'll end up comparing apples to oranges and choosing on price alone.

  1. Pricing transparency — Are receiving, storage, pick-and-pack, kitting, returns, and account-management fees all spelled out? Hidden fees are the #1 complaint about 3PLs.
  2. Service-level agreements (SLAs) — What is the order-cutoff time for same-day shipping? What's the guaranteed order accuracy? What happens when they miss?
  3. Integrations — Native Shopify, Amazon, TikTok Shop, NetSuite? Or a paid middleware layer (e.g., Celigo, Zentail) bolted on top?
  4. Warehouse location(s) — Single facility vs. multi-node. A single Midwest facility hits ~2-day ground to ~95% of the U.S.; coastal-only adds a zone and a day to half your customers.
  5. Operational maturity — How long have they been operating? What's their headcount? Do they cycle-count weekly? Can they show you a sample WMS dashboard?

What questions should you ask in a 3PL discovery call?

  • What is your same-day order-cutoff time, and what % of orders ship same day?
  • What's your contractual order accuracy and on-time-ship rate?
  • Can I see a redacted invoice from a brand my size?
  • What's the all-in cost per order for a brand shipping ~1,000 orders/month with a 0.5 lb average package?
  • Who is my day-to-day account contact, and what's their response-time SLA?
  • How do you handle a stockout, a damaged inbound, or a carrier-caused delay?
  • How are returns received, inspected, and restocked — and what does that cost?

What are the red flags?

  • No published or written SLAs — only verbal promises.
  • Pricing presented as 'we'll customize a quote' with no rate card you can sanity-check.
  • No native ecommerce integrations; everything routes through a third-party connector you have to pay for.
  • High minimums or long lock-in (12+ months) for a brand under 5,000 orders/month.
  • Vague answers about ownership, headcount, or how long the facility has been operating.
