Getting Started with Click Post for a Shopify Store
If you have opened a Shopify store but still feel stuck on shipping, Click Post is often the easiest place to start.
For small and lightweight products, it gives you a flat nationwide rate, tracking, and mailbox delivery without requiring a complicated setup. This article walks through what Click Post is, what you need before your first shipment, and how it fits into a Shopify workflow.

What Click Post Is
Click Post is a Japan Post service for small parcels.
| Item | Details |
|---|---|
| Price | 185 yen nationwide |
| Size limit | 34 cm x 25 cm x 3 cm |
| Weight limit | 1 kg |
| Tracking | Yes |
| Delivery style | Mailbox delivery |
| Compensation | No |
| Payment | Yahoo! Wallet or Amazon Pay |
It is a strong fit for cables, accessories, stickers, books, and other non-fragile items. For a more detailed product fit check, see What Types of Products Work Well with Click Post?.
How it differs from other options
Standard mail may look slightly cheaper for very light items, but the lack of tracking often creates more support burden later. Yu-Packet is also reliable, but usually costs more than Click Post at the same thickness.
Account Setup
What you need
To start using Click Post, you need either:
- A Yahoo! JAPAN ID with Yahoo! Wallet
- Or an Amazon account with Amazon Pay
Basic registration flow
- Visit the official Click Post site
- Log in with Yahoo! JAPAN ID or Amazon
- Agree to the terms
- Finish registration
There is no long screening process, so setup is quick.

What to Prepare Before the First Shipment
The minimum equipment
You do not need a warehouse setup. For most small stores, these are enough:
| Tool | Purpose |
|---|---|
| Printer | Print Click Post labels |
| Envelopes | Outer packaging |
| Cushioning | Protect the product if needed |
| Scale | Confirm the parcel stays under 1 kg |

How Click Post Connects to Shopify
The standard flow is CSV export
Click Post does not directly connect to Shopify as a native shipping carrier. The common flow is:
- Export order data from Shopify or an app as CSV
- Upload the CSV through Click Post bulk application
- Complete payment for each shipment
- Print labels and ship the parcels
- Reflect tracking numbers back into Shopify
The important detail is that bulk application means bulk address registration, not bulk payment. You still finalize each shipment individually.

The first pain point is usually tracking sync
Most first-time users are fine until labels are created. The part that becomes tedious is copying tracking numbers back into Shopify order by order.
It is okay to do this manually when you are just learning. Once your order volume grows, that is usually the first workflow worth improving.

How to Finish the First Shipment
Start with one order, not a large batch
Your first shipment should be a single test order, not a full batch. That lets you understand the screens and sequence without pressure.
Recommended first run:
- Confirm one Shopify order
- Create the shipment manually or from a small export
- Print the Click Post label
- Pack the item and attach the label
- Post it and mark the order fulfilled in Shopify
Once one shipment feels clear, move to CSV for daily use.
Common Questions
Does registration cost money?
No. You only pay per shipment.
Can I drop off Click Post at a convenience store?
No. In practice, Click Post is dropped into a mailbox or brought to the post office.
Do labels expire?
Yes. After payment, you need to ship within the valid period shown by Click Post.
Summary
Click Post is a practical starting point for Shopify merchants selling small, lightweight products. Setup is simple, and the equipment you need is minimal.
Start with one shipment, understand the full flow, then move to CSV-based operations once you are comfortable. If you later want to streamline export and tracking sync together, you can also try Instant Shipping for Click Post.
