Cost per order — fully loaded.
Self-fulfilment fully-loaded cost: $7–$12 per order at 500–2,000 orders/mo. Includes: lease ($3,000+/mo), labour ($25–$30/hr loaded), packaging, software (WMS/OMS/shipping), insurance, equipment depreciation.
3PL fully-loaded cost: $5.50–$8.50 per order in the same volume band. Includes pick & pack, storage, hidden fees but excludes shipping (similar in both models).
Where self-fulfilment wins.
Very low volume (under 200 orders/mo) — 3PL minimum fees punish you, you can do it from a garage cheaply.
Very high volume (10,000+ orders/mo and growing) — at this scale you can negotiate carrier rates directly, lease your own warehouse, hire skilled ops staff and beat 3PL economics by 10–20%.
Highly custom or complex products where the operational know-how is a competitive moat — supplements brands with proprietary kitting, fashion brands with finished-goods QA, etc.
Where 3PL wins.
200–10,000 orders/mo — the wide middle where 3PL economics win on labour, lease, software and carrier rate access.
Multi-city distribution — running your own warehouse in Sydney + Brisbane + Melbourne is operationally heavy; 3PLs offer this as a service.
Peak-season variability — 3PLs flex up; your own warehouse has fixed cost when volume drops post-peak.
Hidden costs of self-fulfilment.
Founder time: the most expensive resource in the business, often spent picking and packing instead of growing.
Software stack: WMS, OMS, shipping platform, returns, inventory management — typically $400–$1,200/month combined.
Carrier access: a brand of your own can't access the volume rates a 3PL has — you typically pay 15–35% more on shipping per parcel.
Capacity planning: peak season requires hiring, training, returning the team — dead cost between peaks.
When to switch from self to 3PL.
When you're past 300 orders/mo and growing.
When founder time on the warehouse floor is preventing growth activities.
When you need geographic distribution beyond your home city.
When peak season creates capacity pain you can't easily flex through hiring.

Get matched →Frequently asked
- At what order volume does 3PL become cheaper than self?
- Typically around 200–400 orders/month, depending on category complexity and how aggressively you're costing your own time. Below 200, self is hard to beat. Above 500, 3PL is hard to beat for most brands.
- Can I move back from 3PL to self at scale?
- Yes — many high-volume brands eventually take fulfilment in-house when they hit 8,000+ orders/month consistently. The economics flip back. But it's a major operational shift.
- What's the most underestimated self-fulfilment cost?
- Carrier rates. Brands that fulfil themselves often pay 20–35% more per parcel than a 3PL with negotiated volume rates. The shipping line on the P&L is the silent killer.
