How to avoid surprise bills when free credits run out

Know when your credits end

Credits usually end in one of two ways: they expire on a date, or they get used up. Many grants have both limits, and whichever comes first wins.

Some grants are also split into parts with different end dates, or unlock in stages. If yours works that way, note each part separately. It is easy to assume you have a year of credits left when part of the balance ends much sooner.

1. Find the expiry date in your billing console, not just in the welcome email. The console is the source of truth.
2. Check the remaining balance and divide it by your current daily spend. That tells you roughly when you will run out.
3. Put both dates in your calendar, with a reminder two weeks before.
4. If you hold several grants, keep them in one list. PerkRadar's claimed page lets you mark the perks you have claimed so they are all in one place.

Set budgets and alerts on day one

Every major cloud lets you set a budget and get an email when spending crosses a threshold. Do this before you launch anything.

A useful pattern is three alerts: one at half your monthly budget, one at 90%, and one at 100%. Make sure the alerts go to an inbox someone actually reads, not just the founder who signed up.

One important detail: on many platforms, budget alerts are based on your gross usage, before credits are applied. That is useful, because it shows what you will pay once credits are gone. Check how your provider calculates it so you are not confused by the numbers.

Alerts are warnings, not brakes. On most clouds, a budget alert does not stop your resources. If you want a hard stop, look for a spending cap or an automatic action, and test it.

Some AI and API providers let you set a hard monthly usage limit on your API keys. Use it, especially for keys that run in production or in agents.

Find out what the credits do not cover

Credits rarely cover everything. You can be well inside your credit balance and still get a bill. Common exclusions to check for in your grant's terms:

• Products bought through a marketplace from third-party sellers.
• Premium support plans.
• Domain registrations and some upfront or reserved purchases.
• Certain services, regions or GPU types, depending on the program.
• Taxes, which may be charged on top of usage.

Hunt down the usual suspects

When a bill surprises someone, the cause is usually something they forgot was running. Look for these regularly, and especially before your credits end.

• Idle servers and GPU instances left on after an experiment.
• Managed databases sized for a launch that never needed that much.
• Disk snapshots, backups and old storage buckets that keep growing.
• Load balancers, static IP addresses and NAT gateways that charge by the hour even with little traffic.
• Data transfer out to the internet or between regions, which is easy to overlook.
• Logging and monitoring that ingests far more data than you read.
• Test projects created by teammates or by AI agents and never deleted.

Tag every resource with a project name and an owner when you create it. When the bill arrives, you can see exactly who and what is spending money.

Plan the landing before you fall off

About a month before your credits end, take an honest look at your real costs. Ask what your monthly bill would be at full price, and whether the business can pay it.

If the number is too high, you have options. You can right-size servers, turn off environments outside working hours, move cold data to cheaper storage, or switch some workloads to a provider with lower prices. Committed-use or reserved pricing can cut costs for steady workloads, but only commit once your usage is stable.

You can also look for a next grant. Some providers have higher tiers you can apply for as you grow, and other platforms run their own startup programs. Browse current offers on PerkRadar, but do not rely on approval. Plan as if you will pay full price.

Do not forget AI and API usage

Cloud servers are not the only source of surprise bills. AI model APIs, speech and voice services, scraping tools and search APIs all charge by usage, and usage can grow very quickly.

A bug that calls a model in a loop, a public endpoint that anyone can hit, or an agent left running overnight can use up a credit grant in hours. Once the grant is gone, the same usage lands on your card.

1. Create a separate API key for each app or environment, so you can see which one is spending.
2. Set a monthly usage limit on every key where the provider allows it.
3. Add rate limits to any public endpoint that calls a paid API.
4. Log the number of paid calls your app makes each day and check it weekly.
5. Revoke keys you no longer use, and never commit keys to a code repository.

Shutting down cleanly

If you decide a project is finished, delete the resources rather than just stopping them. Stopped servers often still pay for attached disks and IP addresses.

Then check the bill for the next cycle to confirm it is zero. If you want to close the account entirely, follow the provider's official account closure steps, and download anything you need first. Finally, remove the card from the account if the provider allows it.
