Most articles comparing 3PL to self-fulfilment are written by 3PL providers, and they reach the conclusion you would expect. This one is written by one too, so it is worth saying plainly at the start: for a lot of Australian brands, self-fulfilment is still the right answer, and pretending otherwise would waste your time and ours.
The useful question is not "is outsourcing better". It is "at what point does the arithmetic change".
What self-fulfilment actually costs
The reason self-fulfilment looks cheap is that most of its cost never appears on an invoice.
Your time. Picking, packing, labelling and getting to the post office. At 100 orders a month and roughly four minutes per order end to end, that is about seven hours — most of a working day, every month, that is not spent on product, marketing or customers.
Space. Stock in a spare room, a garage or a rented storage unit. Sometimes genuinely free, often not, and almost always constraining how much stock you can hold before peak.
Postage rates. Individual senders rarely get the volume rates a fulfilment operation can access. This one is measurable and frequently underestimated.
Errors and their consequences. A wrong item shipped costs you the return postage, the replacement postage, the packing time twice, and sometimes the customer.
The ceiling. The real cost is the one you cannot see: the growth you do not pursue because you already know you cannot pack it.
What a 3PL actually costs
Fulfilment cost breaks into receiving, storage, pick and pack, packaging, returns and postage. Across the Australian market, pick and pack runs roughly A$2 to A$4 per order plus A$0.40 to A$1.50 per additional item, with storage around A$20 to A$45 per pallet per month. The full breakdown is here.
But the number that decides this question for smaller brands is not any of those. It is the minimum monthly charge — commonly A$300 to A$500 per month at Australian providers, applied regardless of volume.
Where the line actually sits
Under about 50 orders a month. Self-fulfil. Almost certainly. The minimum charge alone will exceed your usage cost, and the time you save does not yet outweigh what you pay for it. Any provider telling you otherwise is selling.
Roughly 50 to 150 orders a month. The genuinely difficult zone. Packing is now eating real time, but most national providers either will not take you or will price you against a minimum you do not reach. This is where brands get stuck, and it is the range smaller, growth-focused providers exist to serve.
Roughly 150 to 500 orders a month. Outsourcing usually wins on time alone, and you are approaching the volume where more providers want your business. Worth getting quotes.
Above 500 orders a month. Self-fulfilment is now actively constraining the business. The question is which provider, not whether.
These are ranges, not rules. A brand shipping 80 heavy, slow-moving orders is a different problem to one shipping 80 lightweight accessories.
Four questions that decide it faster than a spreadsheet
- How many hours a week does fulfilment take you? Multiply by what an hour of your time is worth to the business, not by minimum wage.
- Is stock capacity limiting what you order? If you are under-ordering because of space, that is lost revenue.
- What happens if you take two weeks off? If the answer is "orders stop", you do not have a business yet — you have a job.
- Would you be invoiced a minimum charge? If your usage cost is below it, you are paying for capacity you will not use.
The honest recommendation
If you are shipping under 50 orders a month, keep packing. Revisit it when packing starts costing you a day a month or stopping you taking a break.
If you are somewhere between 50 and a few hundred and every quote you have received assumed you were bigger, that is a pricing problem rather than a fulfilment problem — and it is the specific gap Parcelo is built for. We do not apply a minimum monthly invoice, so a quiet month costs less rather than the same.
