Format numbers as currency

This is real work, not a feature someone invented — it comes from real job ads and real questions people asked. Below are four ready AI prompts: get it done, make it easy for the next person to say yes to, work out the right move when you are stuck, and stop it coming back.

The same task, four prompts

Take the price of the new server, 12,500, and the old server's trade-in value, 3,000, and display the net cost on the invoice for the client, formatted as US dollars.

Before showing the final quote to the client, make sure all the line item costs and the total for the new servers are formatted as currency, so there's no confusion about what they're paying, especially the tax.

The client is balking at the invoice total, saying it looks like a plain number not money.
I just sent the invoice for the server upgrade to Sarah and she's saying the numbers look wrong, like raw digits instead of currency. I'm afraid she'll think we're unprofessional and delay payment. I can't tell if it's just her browser or if I missed a step. How do I quickly confirm it's formatted correctly for her and what's the best way to fix it if it's not?

I keep getting questions about number formats on client-facing documents.
I'm constantly getting questions from clients, and even internally from sales, about how numbers are displayed on quotes and invoices. It's usually about currency or percentages. This wastes a lot of time and makes us look sloppy. What habit should I change to ensure all financial figures are always correctly formatted before anyone else sees them?

Questions people actually ask

honest answers, no sign-up

Every task here was seen in the real world. Someone doing the job named it, a real job ad asked for it, or a lot of people asked about it online.

If nothing real showed a task, it is not on the page. That is the whole rule.

They are the same job approached four ways, because what you need depends on where you are.

Get it done today. Make it easy for the next person to say yes to. Work out the right move when you are stuck. Learn the pattern so the job stops coming back.

For most of these jobs it can carry the heavy thinking - draft it, sort it, check it, rehearse it with you.

It cannot sit in your chair, take the blame when a number is wrong, or notice what nobody wrote down. Let it do the first 80%. Keep the last 20% that is truly yours.

No. Copy any prompt and paste it into the AI you already use. No account, no score, no wall in the way.

Any of them. The prompts describe the work rather than naming a product, so they are not tied to one assistant.

That is also why they keep working when you switch.

Change it freely. Every prompt is a starting line, not a rule.

Put in your real numbers, your real names and your real deadline. The more you make it yours, the better the answer comes back.

The tasks come from real job ads, published job data and the questions people ask in public forums.

The steps come from JavaScript's own documentation, with practitioner sources for the traps the manual does not mention.

Push once. Ask it to sharpen the weakest part and to say what it assumed.

Most wrong answers come from a missing detail rather than a bad prompt - tell it the thing it could not know.
