Hidden Costs Breakdown

1

Unexpected Charges Despite Free Credits

critical overage

Multiple users report being charged real money despite having free trial credits or startup credits that were not applied. Credits are often siloed and do not apply to all services, leading to unexpected debt.

trustpilot

Accidentally incurred €327 in API costs despite having €264 in free startup credits that weren't used. Support is intentionally hidden and unreachable - clearly designed to prevent refund requests.

trustpilot

I have been charged 20 pound while i have around 200 pound credit. They hidden their customers service like cowards . I couldnt even reach a human to talk too or email after half hour absolutely ridiculous.

2

No Hard Spending Limits Available

high overage

Google Cloud does not offer hard spending caps for pay-as-you-go services. Billing alerts exist but do not prevent charges from exceeding a set threshold. Users who misconfigure services or experience unexpected usage spikes can accumulate large bills with no automatic stop.

trustpilot

The inhability to stablish hard limits for expenses in pay-as-you-go services is predatory. I understand that is targeted to avoid service interruptions, but there must be a hard limit option to stablish some cuantity avobe wich a business cannot continue operating.

3

Opaque Billing and Credit Applicability

high addon

Google Cloud's billing structure is reported as non-transparent, with credits not automatically applied to all services. The $300 free trial credit does not cover all API products, creating confusion for new users who assume credits apply universally.

trustpilot

The platform advertises a flat '$300 Free Trial Credit' with zero front-facing warnings or asterisks indicating that this credit is explicitly walled off from the Gemini Developer API (AI Studio).

trustpilot

They hype up "free credits" from promotions like Gemini Code Assists or startup programs, but these don't actually prevent charges—sudden debits hit without warning or clear breakdowns.

4

Security Incident Costs Not Covered

critical support

Users who suffer security attacks (such as API key compromise or permission escalation) report being held liable for charges incurred during the attack, with no recourse or refund from Google Cloud.

trustpilot

We were the victim of a permission escalation attack which cost us thousands of pounds. The details of which is publicly known and can be found if you search: "truffle security google api keys" Despite the fact that Google knows about this security issue and publicly stated they were going to resolve it, when we were a victim of this attack they said we were liable.
