How to Choose a 3PL for Your E-commerce Business (From Someone Who's Done It)

Choosing a 3PL is one of those decisions that feels like it should be straightforward but absolutely isn't. I've been through this process multiple times, both for my own DTC brand and with clients, and I've learned the hard way that the flashy sales pitch rarely matches the day-to-day reality.

When it's actually time to switch to a 3PL

Not every business needs a 3PL. If you're shipping 20 orders a day from your spare room and it's working, there's no rush. But when fulfilment starts eating into your time so much that you can't focus on growth, or when you're turning down wholesale opportunities because you can't handle the volume, that's when it's time.

The tipping point is usually somewhere between 50-150 orders per day, depending on your product complexity. If you've got simple SKUs and standard packaging, you can push the in-house model further. If you've got kitting, subscriptions, or custom inserts, the complexity pushes you toward a 3PL sooner.

What to actually evaluate

Forget the glossy capability decks. Here's what actually matters:

• Location relative to your customers. Where are most of your orders going? A 3PL based in the Midlands makes sense for broad UK coverage. If 40% of your orders go to London, maybe a site closer to the M25 is worth the slightly higher per-unit cost because you'll save on shipping.
• Tech integration. Can they plug directly into your Shopify store? Do they support Recharge for subscriptions? What does the integration actually look like? Is it a proper API connection or are they downloading CSV orders twice a day? Real-time sync matters more than you think.
• Minimums and pricing structure. Some 3PLs charge per pick, some per order, some a flat monthly fee. Understand the model and run the numbers on YOUR average order. A cheap per-pick rate is useless if your average order has 4 items and they charge per pick.
• Error rates. Ask them directly: what's your mis-pick rate? What's your damage rate? Then ask for references and check. A 2% error rate sounds small until you realise that's 20 angry customers per 1,000 orders.
• Flexibility. Can they handle seasonal spikes? What happens at Black Friday? Will they do custom packaging, handwritten notes, or marketing inserts? Some 3PLs are brilliant at standard fulfilment but fall apart when you need anything bespoke.

The questions nobody thinks to ask

• What happens when something goes wrong? What's the escalation process? Who's my day-to-day contact?
• How do you handle returns? Is there a grading process or does everything go back to shelf?
• What's the onboarding timeline? (If they say less than 2 weeks, be sceptical.)
• Can I visit the warehouse before signing? (If they say no, walk away.)

Red flags I've seen

• No dedicated account manager, and you're just emailing a generic inbox.
• They can't clearly explain their billing structure.
• Their tech platform looks like it was built in 2008.
• They won't share current client references in your product category.
• They charge penalties for low volume months.

How to run a proper evaluation

Don't just go with the first one that quotes you. Shortlist 3-4, visit at least 2 in person, and run a trial period with your actual products if possible. Send test orders. See how they handle a mis-pick. Test their customer service response time.

The right 3PL becomes a genuine partner in your business. The wrong one becomes an expensive headache that your customers feel every day.
