Five terms to check before topping up: balance, refunds and expiry, question by question

Why ask before paying

Prepayment is fundamentally you lending it money, interest-free and unsecured. Your only evidence is the terms it publishes on its pages.

And the overwhelming majority of people do not read the terms at the moment they pay. When refund season arrives, they discover the terms contained a pile of conditions nobody noticed.

The five questions below take ten minutes to settle before paying.

Question one: does the balance expire?

What to ask, in plain words: "Does the topped-up balance have an expiry date? Will it be zeroed or frozen at some point?"

Common answers and the risk they carry:

Always read the actual terms. Some sites advertise "valid forever" on the page while the terms say "final interpretation rests with the site".

Question two: refund conditions and fees?

What to ask, in plain words: "Can the balance be refunded? Under what conditions? What is the fee? How long until it arrives?"

Four conditions to be wary of:

1. "Minimum X to qualify for a refund." A threshold is not unreasonable in itself, but a high one signals reluctance.
2. "20% to 30% processing fee." That is far above what a payment channel actually costs, usually 0.6% to 1%. The difference is what the site keeps.
3. "Refunds take 30 business days." Stalling is a signal that cash is tight.
4. "Bonus credit is non-refundable." Reasonable, but check whether it counts your paid top-up as part of the "bonus". Some sites define it that way.

A relatively healthy answer: "Refunded at the remaining paid amount, 5% fee, within 7 business days." That structure shows a refund process exists and the cost is transparent.

Question three: what if it disappears?

The real purpose of this question is not the answer — of course it will say "we will not disappear" — but to watch the reaction:

• It answers directly and gives information about the operating entity → relatively credible.
• It replies only "we will not disappear" and dodges the entity question → high risk.

What you can actually do about risk:

1. Check the entity. Is there a company you can look up? Does the site's footer show a registration number? Sites operating compliantly in mainland China usually carry an ICP filing.
2. Check how long it has existed. Domain registration date, history of community discussion. New sites, under six months old, carry the highest risk for large prepayments.
3. Do not prepay large amounts. This is the most effective measure; everything else is secondary.

One hard rule: a single top-up should not exceed one month of your actual usage. Then even a total loss costs you one month. Any "top up more for a bigger discount" temptation should be measured against this rule.

Question four: package or balance first?

What to ask, in plain words: "If I have both a subscription package and a top-up balance, what is the deduction order? If the package is not fully used, does the balance expire?"

Very few people ask this, and it is very practical:

• If the balance is deducted before the package, you will never get to the package while your balance drains.
• If the package has its own expiry, you may have paid for it and barely used it.

Ask it to state the deduction order explicitly and publish it on the page.

Question five: can the billing basis be confirmed in writing?

What to ask, in plain words: "What official baseline price does the multiplier refer to? Are input and output priced the same? Is there a platform fee or minimum spend?"

Why it has to be asked:

• "0.5x" has a different baseline at different sites. Some use the official input price, some the official output price, some an average.
• The ratio between input and output pricing varies a lot, with output typically three to five times more expensive. If the multiplier only applies to input, the actual bill differs substantially.
• Some sites have a minimum spend or monthly fee that is not prominent on the page.

How to verify: after topping up, run a small reconciliation. Send one request with a known input and output length and check whether the charge equals (input tokens × unit price + output tokens × unit price) × multiplier. Within 5% is normal, given token-counting differences. Above 30% is a question worth asking.

A pre-payment checklist

[ ] Balance expiry - a clear statement, consistent with the terms
[ ] Refund conditions and fee - fee under 10%, arrival within 15 business days
[ ] Operating entity verifiable - registration number or company information
[ ] Site longevity - domain registered over 6 months, ongoing update history
[ ] Deduction order - priority between package and balance is clear
[ ] Billing basis - multiplier baseline, input/output parity, minimum spend
[ ] Single top-up <= one month of usage   <- more important than everything above

One last word

If all six items get clear, written answers, the site passes on transactional propriety.

But no set of terms prevents a shutdown. Terms only improve your odds of recovering something afterwards. They do not reduce the probability of it happening.

What actually protects you is your top-up strategy, not reading the terms. Treating "never prepay large amounts" as an unbreakable rule beats studying any set of terms. Our monitoring data can help you watch how a site's stability changes over long-term use — but again, that is a judgement aid, not a guarantee.
