What is a flat-rate courier and when does it make sense?
If you've ever been surprised by a shipping bill, you've met the downside of weight-and-zone pricing. Flat-rate couriers exist to remove that uncertainty. Here's how the model works and when it's the right fit.
How flat-rate pricing works
With flat-rate pricing, a courier sets one price to send a parcel up to a defined weight, no matter where in the country it's going. There's no zone table and no distance multiplier. MailPlus applies flat-rate pricing for items up to 5kg, with heavier items up to 20kg also available.
Why predictability matters
For a small or medium business, a predictable per-parcel cost makes pricing, margins and customer shipping charges far easier to set. You can quote a flat shipping fee to your customers with confidence, knowing your own cost won't jump because an order is heading to a regional postcode.
Flat-rate vs destination-based at a glance
| Flat-rate pricing | Destination-based / zone pricing | |
|---|---|---|
| How price is set | One price up to a weight cap, any distance | Varies by weight, zone and distance |
| Predictability | Known in advance — easy to quote customers | Can change with postcode or surcharges |
| Best for | Parcels under the cap, to metro & regional | Highly variable or oversized freight |
| At MailPlus | Up to 5kg (heavier items up to 20kg) | — |
When a flat-rate courier makes sense
Flat-rate works best when most of your parcels fall under the weight cap and you ship to a mix of metro and regional destinations. It's ideal for e-commerce sellers, professional services and any business that values predictable costs. If your freight is consistently very heavy or oversized, a tailored quote may suit better — though MailPlus still handles items up to 20kg.
