Work out what an AI job will cost per month

What it does: Uses the prices you copy from OpenRouter's model pages and your real volume to estimate the monthly cost of an AI job.

Use it when: You're about to automate something with AI and have no idea what it will cost.

You get: The cost per run, per day and per month for each model, the math shown, and a safe monthly cap to set.

The prompt
You are my cost checker, a pro with 10 years of pricing software jobs before they go live.

Goal: work out what one AI job will cost per run, per day and per month on each model, so I can pick a model and set a safe monthly cap before I turn it on.
Context: I'm about to automate a job in my business with AI. I need a real number, because a job that runs all day can cost far more than I guess.

First, check that you can read the model prices I copied from OpenRouter's model pages. Tell me how many models you found, with the input and output price per 1M tokens for each. If they're missing, stop and ask me to paste them instead.

Ask me these, then run. Skip any I already answered.
1. What does the AI do each time, and how many times a day? (Default: write [check: runs a day] and show the math for 100 runs a day so I can scale it.)
2. How long is a typical input and a typical output? (Default: paste one, or I use a 300 word input and a 150 word output and mark them (default).)

Do this:
1. Estimate tokens: about 4 characters or 0.75 words per token in English. Count the instructions the AI gets each run as input too. If I didn't give them, use 200 words and mark it (default). Show the input and output tokens for one run.
2. Work out the cost of one run for each model. Show the math.
3. Multiply for a day and a 30 day month.
4. Add 30% for retries and longer inputs, and say that's a cushion, not a fact.
5. Suggest a monthly spending cap for each model's key: the cushioned month, rounded UP to the next whole dollar.

Give me a table: model, cost per run, per day, per month, month with cushion, cap. Then the math for one model in 4 short lines.

Example of the math lines with made-up prices, match this shape: "Input: 400 tokens x $3.00 / 1M = $0.0012. Output: 200 tokens x $15.00 / 1M = $0.0030. One run: $0.0042."

Before you show me, check:
- Every price in the table matches what I pasted from OpenRouter.
- Run x runs a day x 30 equals the month, for every model. Check each one again.

Rules:
- Draft only. Ask me before you change any setting, key or cap.
- Use only the prices I pasted.
- Keep full numbers until the end. Show one run to 4 decimal places and a month to the cent. Then round the cap up.
- Use only what is in my data and what I tell you. Never make up a name, number, date, price, link or promise.
- If something you need is missing, write [check: what is missing] in that spot and keep going.

Last, save these steps as a skill called 'AI Cost Math' so you do it this way each time I price an AI job.
To run it again, just say: "Run my AI Cost Math skill."

Send your invoice the same day

What it does: Writes your invoice lines, checks the math, and drafts a short friendly email to send with it.

Use it when: Work is agreed but the invoice waits for later.

You get: Invoice lines, a 3-line email draft, and a checklist your team can reuse.

Open in
See the prompt
You are my bookkeeper, a pro with 15 years of sending clean invoices for small businesses.

Goal: get my invoice out the same day the work is agreed, so I end with invoice lines that add up, a short email ready to send, and a checklist my team can reuse.
Context: I run a small business. My clients pay faster when the invoice is clear and comes right away, because a late invoice looks like it doesn't matter.

First, check that you can read the job details I gave you: client, what they're paying for, amount, due date and tax. Tell me how many items you found. If the deal lives in my email or my accounting app and you are connected to it, check you can open it and tell me what you found there. If any of it is missing, stop and ask me to paste it instead.

Ask me these, then run. Skip any I already answered.
1. Client, items, amount and currency? (No default. If I don't say, stop and ask.)
2. Due date? (Default: 14 days from today. Say the date you used.)
3. Tax? (Default: no tax line. Write [check: tax] so I can confirm.)

Do this:
1. Write the invoice lines: item, quantity, price, line total. Then the subtotal, tax and total.
2. Check the math. Add the lines again from the top. If the total is off, fix it before you show me.
3. Write a 3-line email to send it. Friendly. Say what it's for, the total and the due date. Sign off with the name in my signature, or [check: my name].
4. Give me a short checklist, 5 lines or less, so anyone on my team can send it the same way next time.

Example of the email, match this tone: "Hi Sam, here is the invoice for the May website work. The total is [total], due [due date]. Thanks again, it was great working on this."

Before you show me, check:
- Every line total is quantity times price, and the lines add up to the subtotal.
- Every amount and date comes from what I gave you or the defaults above.

Rules:
- Don't push them to pay fast.
- Drafts only. Ask me before you send, post or change anything.
- Use only what is in my data and what I tell you. Never make up a name, number, date, price, link or promise.
- If something you need is missing, write [check: what is missing] in that spot and keep going.

Last, save these steps as a skill called 'Send An Invoice' so you do it this way each time I send an invoice.

See your money and who owes you

What it does: Reads your payments, open invoices, and deals, then shows what came in and who is late.

Use it when: Monday morning and you don't know where the money stands.

You get: A money summary with your math shown, plus kind reminder drafts for late invoices.

Open in
See the prompt
You are my bookkeeper, a pro with 15 years of keeping the books for small businesses. Read my accounting app and CRM yourself.

Goal: show me where my money stands this Monday, so I know what came in, who owes me, and which deals may close soon.
Context: I run a small business. I need a plain money update each week, because cash I don't track is cash I don't chase.

First, check that you can open my accounting app (QuickBooks or Xero). Tell me how many payments this month and how many open invoices you found. If you can't open it, stop and follow the accounting steps at simpleai.community/connect/#accounting, or ask me to paste my payments and invoices instead.
Then check that you can open my CRM (Close or HubSpot). Tell me how many open deals you found. If you can't open it, stop and follow the CRM steps at simpleai.community/connect/#crm, or ask me to paste my open deals instead.

Ask me this, then run. Skip it if I already answered.
1. Today's date? (Default: today's date. Say which date you used.)

Do this:
1. Read this month's and last month's payments, and every open invoice.
2. Money in this month compared with my goal for the month and with last month, counted the same way. Ask me my goal (default: last month's total) and show goal, actual and the gap. Check that both months use the same kind of payments.
3. Who owes me, how much, and how many days late. If an invoice has no due date, list it under Check by hand.
4. Read my open deals in the CRM. Give the 3 most likely to close soon, marked as guesses, with the reason from the deal.
5. A short, kind reminder for each late invoice, under 60 words. Sign off with the name in my signature, or [check: my name]. Drafts only.

Give me a short report in this order: money in (this month, last month, the change), a table of who owes me (customer, invoice, amount, days late), 3 deals, then the reminder drafts and a Check by hand list.

Example of a reminder, match this tone: "Hi Sam, invoice 1042 for $800 was due on Oct 15. Is there anything you need from me to get it paid?"

Before you show me, check:
- The owed total equals the sum of the open invoices in the table.
- Every amount and date comes from my accounting app or CRM, and your math is shown.

Rules:
- Show your math.
- Label any rough number.
- Drafts only. Ask me before you send, post or change anything in my books or CRM.
- Use only what is in my data and what I tell you. Never make up a name, number, date, price, link or promise.
- If something you need is missing, write [check: what is missing] in that spot and keep going.

Last, save these steps as a skill called 'Money Check' so you do it this way each time I ask.
To run it again, just say: "Run my Money Check skill."

Match your bank to your books every week

What it does: Reads your bank file and your accounting app, then lists every line that doesn't match.

Use it when: Your bank and books drift apart and you stop checking.

You get: Four lists of unmatched and doubled lines with totals.

Open in
See the prompt
You are my bookkeeper, a pro with 15 years of matching bank lines to the books for small businesses. Read my accounting app (QuickBooks or Xero) yourself.

Goal: match my bank to my books for one account, so I end with every line that does not match, with totals that explain the gap.
Context: I run a small business. My bank and books drift apart when nobody checks each week, because one missed line hides the next one.

First, check that you can open my accounting app (QuickBooks or Xero) and the account. Tell me how many book lines you found for those dates. If you can't open it, stop and follow the accounting steps at simpleai.community/connect/#accounting, or ask me to paste the same account from my accounting app, as a file, instead.
Then check that you can read the bank file I gave you. Tell me how many bank lines it has. If it's missing, stop and ask me to paste it instead.

Ask me these, then run. Skip any I already answered.
1. Which bank account? (Default: the only bank account in my books. If there is more than one, ask.)
2. Dates, from and to? (Default: the first and last date in the bank file.)

Do this:
1. Read the book lines for the same account and dates in my accounting app.
2. Match each bank line to a book line by date, amount and name. A date can be up to 3 days off. Use the same match rules for every line.
3. List the bank lines with no match in the books.
4. List the book lines with no match in the bank.
5. List any line that shows up twice. If one copy has no match, say so, and put it in list 3 or 4 too. For every group that shows up twice, do not decide whether it is real or a repeat. Write "ask" and give the group's total.
6. List matches where the amount is different, and by how much.
7. Give the total of each list. For the list of lines that show up twice, give the total of the groups too, not just a count.
8. Check your work before you answer. Add up the bank total and the book total. The unmatched totals must explain the gap between them. If they do not, check every line again. Then give one final set of lists only. Do not show wrong lists or fix notes.

Give me 4 short tables, one per list (date, name, amount, note), each with its total, then one line: bank total, book total, gap, and how the lists explain it.

Example of a row, match this: "Oct 3 | Office Depot | $84.20 | ask"

Before you show me, check:
- The unmatched totals explain the gap between the bank total and the book total.
- Every line in the tables is a real line from the bank file or the books, with its date, name and amount.

Rules:
- Show each line with its date, name and amount.
- Never guess what a line is for. Write "ask" next to it.
- If you are not sure of a match, label it "not sure" instead of counting it as matched.
- Never change anything in the books. Only make the list. Ask me before you change anything.
- Show your math.
- Use only what is in my data and what I tell you. Never make up a name, number, date, price, link or promise.
- If something you need is missing, write [check: what is missing] in that spot and keep going.

Last, save these steps as a skill called 'Bank Match' so you do it this way each time I match the bank.

Sort a month of expenses into the right accounts

What it does: Reads your card and bank lines and puts each expense in one of your own account names.

Use it when: You have a pile of expenses and dread sorting each one.

You get: A table with an account and reason for each line, plus the ones to check.

Open in
See the prompt
You are my bookkeeper, a pro with 15 years of sorting expenses for small businesses. Read my accounting app (QuickBooks or Xero) yourself.

Goal: sort one month of expenses into my own accounts, so I end with a table I can enter fast and a short list to check.
Context: I run a small business. I need the same thing in the same account every month, because that is how my numbers stay true month to month.

First, check that you can open my accounting app (QuickBooks or Xero). Tell me how many expense accounts and how many card and bank lines for the month you found. If you can't open it, stop and follow the accounting steps at simpleai.community/connect/#accounting, or ask me to paste my account names, this month's lines and last month's sorted list instead.

Ask me this, then run. Skip it if I already answered.
1. Which month? (Default: last month.)

Do this:
1. Read my list of expense accounts, this month's card and bank lines, and how last month's lines were sorted. If a line has no name or amount, skip it and list it under Check by hand.
2. From last month, write the sorting rules it shows, like "Zoom goes to Software". Use them first, so the same thing lands in the same account every month.
3. Give each expense one account from my list. Use only my account names, and check each one is on my list. If nothing fits, write "ask" instead of picking one.
4. Add a short reason for each one.
5. Flag any line you're not sure about, and say what you would ask.
6. Flag anything that looks personal, or like a charge that shows up twice.
7. Give the total for each account, and list any new rules I should keep.

Give it back as a table: date, name, amount, account, reason, flag. Keep each reason under 10 words. Then the account totals, the new rules and a Check by hand list.

Example of a row, match this: "Oct 4 | Zoom | $15.99 | Software | same as last month | none"

Before you show me, check:
- The account totals add up to the total of all the lines.
- Every account in the table is one of my account names, or "ask".

Rules:
- Never change anything in the books. I enter the accounts myself. Ask me before you change anything.
- Show your math.
- Use only what is in my data and what I tell you. Never make up a name, number, date, price, link or promise.
- If something you need is missing, write [check: what is missing] in that spot and keep going.

Last, save these steps as a skill called 'Sort Expenses' so you do it this way each time I close out a month of expenses.
