Credits and Refund Policy

1. Credit lifetime

Credits can be used for 1 year from your most recent purchase. A new purchase adds the credits together and restarts the 1-year period. Expired credits are lost in full.

2. Tester package (50 free slips)

Given once per mobile number. It has no cash value and cannot be exchanged for money or refunded.

3. Refunds

• Package fees are not refunded in any case
• Paying twice or paying too much by mistake: the excess is refunded or turned into credits, as the customer chooses, within the time the team tells you
• A fault in Checkslip's own system that takes a credit without a real check: the credit is given back

4. Paid but no credits

Send the proof of payment and your account email through LINE OA. The team checks and adds the credits within 1 business day.

5. Payment channels

Pay through Stripe by card or PromptPay QR, with credits added automatically, and any other channel the Company sets.
