5 Questions to Ask Before Choosing a 3PL Partner

Choosing a 3PL is like choosing a business partner. Get it right, and they make you look good. Get it wrong, and your customers blame you for their mistakes.

We've been in fulfillment for over 30 years. We've seen brands come to us after nightmare experiences with other providers. The horror stories have patterns.

Here are the five questions that would have saved them the pain.

Why This Matters

Every 3PL will tell you they're accurate. Press them on the number.

Industry standard is around 97%. That sounds good until you do the math: at 1,000 orders/month, 97% accuracy means 30 wrong orders. Thirty angry customers. Thirty replacement shipments. Thirty hits to your reputation.

Good 3PLs operate at 99%+. Great ones hit 99.5-99.8%.

What to Listen For

• Specific numbers — Vague answers like "very high" are red flags
• How they measure — Do they track errors caught before shipping AND errors that reach customers?
• Trend data — Is accuracy improving or declining?

Why This Matters

Things will go wrong. Products will be damaged. Orders will be mispicked. Shipments will get lost. The question isn't if — it's how they handle it.

What to Listen For

• Clear escalation process — Who do you contact? How fast do they respond?
• Proactive communication — Will they tell you about problems, or do you have to discover them?
• Resolution ownership — Do they fix the problem, or do they hand you a credit and wish you luck?
• Root cause analysis — Do they figure out why it happened to prevent repeats?

Ask for specific examples. "Tell me about a time a major error happened and how you handled it." Their answer reveals their culture.

Why This Matters

Anyone can provide a glowing reference from a new client in the honeymoon phase. The real test is clients who've been through the ups and downs.

What to Listen For

When you talk to that reference, ask:

• "What's the most frustrating thing about working with them?"
• "Have you ever considered switching? Why or why not?"
• "How have they handled your growth?"
• "What do you wish you'd known before signing?"

If they can't provide long-term references, ask why. High client turnover is a massive red flag.

Why This Matters

Your 3PL might be great at handling your normal 500 orders/week. But what happens during Black Friday when you hit 2,000? Or when a product goes viral and you 10x overnight?

What to Listen For

• Staffing flexibility — Can they scale labor up quickly?
• Space availability — Is there room to expand, or are they already at capacity?
• Communication expectations — How much notice do they need for volume changes?
• Peak season track record — How did last Q4 go?

Why This Matters

3PL pricing is notoriously opaque. The per-order rate you're quoted is rarely what you'll actually pay.

Hidden Fees to Ask About

• Receiving fees — What does it cost to check in inventory?
• Storage fees — Per pallet? Per cubic foot? Per SKU?
• Pick fees — Is it per order or per item? What about multi-item orders?
• Packaging materials — Are boxes/tape/filler included or extra?
• Account management fees — Some charge monthly minimums or platform fees
• Integration fees — Connecting to your Shopify/WooCommerce/etc.
• Return processing fees — What happens when items come back?
• Special handling fees — Kitting, bundling, gift wrapping

Ask for a sample invoice from a client with similar volume and complexity. If they won't show you one, walk away.

The Bonus Question

Here's one more that separates good 3PLs from great ones:

A 3PL that says they're perfect for everyone is lying. Good partners know their strengths and weaknesses. They should be able to articulate:

• The types of clients they serve best
• Volume ranges where they excel
• Industries or product types that aren't a good fit

If they're honest about their limitations, they're more likely to be honest about everything else.

The Real Test

Here's what these questions really measure: transparency and communication.

A 3PL that answers these questions directly, with specifics, without getting defensive? That's a partner who'll communicate the same way when problems arise.

A 3PL that dodges, deflects, or gives you marketing speak? That's what you'll get when something goes wrong with your orders.

Choose accordingly.
