If you've started googling "how to stop shipping orders myself," you've already found about fourteen conflicting opinions. FBA evangelists, 3PL salespeople, and Reddit threads from five years ago all seem equally confident that they have the answer. The reality is that the right fulfillment model depends almost entirely on your product, your volumes, and the stage of your business. This is a plain-English breakdown of the real tradeoffs — written for brands doing serious volume without enterprise scale.
The three models — what each one actually means in practice
Before comparing, it's worth being clear about what you're actually choosing between.
Self-fulfillment means you — or your team — pick, pack, and ship every order yourself, from your own location. You buy postage, you manage inventory, you handle the printer jam at 9pm before a shipping cutoff. It's the most control, and the most work.
FBA (Fulfillment by Amazon) means you send inventory to Amazon's warehouses, and Amazon ships orders to your Amazon customers. When someone orders through Amazon, the logistics happen automatically. The catch: you have to sell on Amazon, you play by Amazon's rules, and your product needs to work within their system.
Third-party logistics (3PL) means you send inventory to a fulfillment warehouse, and they ship your orders on your behalf — regardless of where you sell. Your Shopify store, your website, marketplaces other than Amazon. A 3PL is logistics infrastructure you rent rather than own.
FBA — where it works, where it doesn't, and the hidden costs people forget
FBA is genuinely excellent for the right product. If you're selling a commodity with consistent dimensions, standard packaging, and high volume on Amazon, FBA's economics can be hard to beat. The Prime badge, the integrated logistics, the automated returns — it's a powerful system when you fit inside it.
The problem is the "when you fit inside it" part.
FBA charges you for every cubic inch your product sits in their warehouse, on a monthly basis that doubles during Q4. Products that don't sell fast enough get hit with long-term storage fees. Products that don't meet their labeling requirements get rejected or returned at your cost. Products with unusual dimensions, fragile components, or any hazmat flags enter a whole separate compliance process.
And critically: FBA fulfills Amazon orders. If you're selling through your own website, through a specialty retailer, through any channel that isn't Amazon, FBA does nothing for those orders. Multi-channel fulfillment (MCF) exists, but the fees are higher and the delivery promise is weaker.
FBA works best for: Commodity products, high volume on Amazon, standard dimensions and packaging, non-specialty goods.
FBA doesn't work well for: Specialty or niche products, multi-channel sellers, brands who don't want to be dependent on Amazon, products with unusual requirements.
Third-party logistics — what to look for, what to avoid, and when it makes sense
A 3PL fulfills your orders from their warehouse, using your inventory. The right 3PL gives you professional-grade logistics without owning the infrastructure: warehouse space, packing staff, carrier relationships, and the operational systems to run it all.
The 3PL market is wide. At one end, you have enterprise operations with sophisticated warehouse management systems, automated conveyors, and minimum volume requirements in the tens of thousands of orders per month. At the other end, you have smaller, more focused operations — like us — built specifically for brands that don't yet have enterprise scale.
What to look for in a 3PL:
- Transparent per-order pricing, not bundled tiers that obscure the real cost
- No long-term contracts or steep minimums if you're still growing
- A real person to talk to — not a ticket system as your only contact
- Clear SLAs: when does your order actually ship?
- Returns handling, not just outbound shipping
What to watch for:
- Vague setup fees or onboarding costs
- Volume minimums you can't reliably hit
- Lock-in contracts that make it hard to leave if the relationship isn't working
- No clear answer on what happens to your inventory if something goes wrong
3PL works best for: Brands doing consistent volume across any channel, specialty products that don't fit FBA, brands who want to own their customer relationship, and anyone who needs more than Amazon fulfillment.
Self-fulfillment — what it really costs when you count everything honestly
The postage is the easy part.
Most founders who ship their own orders undercount the true cost significantly. The postage and packaging materials show up on the credit card statement and feel like the cost of fulfillment. But there's a longer list.
The costs most people count:
- Postage (usually at retail rates, not commercial rates)
- Packaging materials
- Label printer, tape, scales
The costs most people undercount:
- Your time, at whatever your hourly rate is worth
- Errors — mispicks, wrong labels, damaged goods — and the customer service they generate
- Weekend and evening hours to hit shipping deadlines
- Space — whether you're paying for it or using personal space that has a real opportunity cost
- The mental load of managing inventory as your store of record
The costs almost no one counts:
- The sales you didn't make because you were packing orders
- The product improvements you didn't ship
- The relationships you didn't build
Self-fulfillment is the right answer at the very beginning, when volume is low, margins are thin, and every dollar counts. It becomes the wrong answer somewhere between 50 and 200 orders a month for most brands — not because you can't handle it physically, but because the opportunity cost starts to outweigh the savings.
A simple decision framework
If you're shipping fewer than 50 orders a month and margins are thin: self-fulfill. It's not worth the fixed cost of a 3PL yet.
If you're on Amazon with a standard product and growing volume: FBA is worth serious evaluation.
If you're doing 50–5,000 orders a month, selling across your own channels, and your product doesn't fit Amazon's mold: a 3PL that's built for your scale is probably the right answer.
If you're losing weekends, making errors, and struggling to keep up: you've already answered the question. The question now is just which 3PL.
The questions to ask before you commit to any model
Before signing anything or sending your first inbound shipment:
- What's the real per-order cost, including storage and postage?
- What happens to my inventory if I want to leave?
- Who is my actual point of contact day-to-day?
- What's the returns process, and what does it cost?
- Can I see an example of a real invoice?
The right answers aren't always the same for every brand. But the willingness to answer them clearly is usually a good signal about the partner you're about to work with.
