Show promptHide prompt

The agent reads the open items list and keeps only the invoices whose due date has passed. It groups them by client and drafts one polite reminder per client, with every open invoice and the total owed. You check the drafts before anything leaves your account.

Before you start

  • Prepare the open items list from your billing system as a table or as a text file.
  • This is not legal advice; check your payment terms and local rules on reminders with a qualified adviser.

The prompt

Goal: Draft polite payment reminders for overdue invoices in [Open items list] for [Company name].
Context: Use Code execution and file creation to total the amounts per client from the table. Show the reminders in Artifacts, so I can edit them beside the figures.
Steps:
1. Read the table and list only the rows with a due date before today.
2. Sort the overdue rows by client name and total the amounts for each client.
3. Write one polite reminder per client that lists every open invoice and the total.
4. Flag any row with a missing amount or a missing due date, and draft no reminder for it.
Output: A short summary of the totals and the reminders, one client at a time.
Ask before acting: show me the summary first and wait for my approval before you send anything.

Match bank statement credits with the open invoices

Match the credits on a bank statement against open invoices and see which look settled, part settled or open, with a reason for each.

Show promptHide prompt

The agent reads the credits on your bank statement and compares them with the open invoices you list. It works out how much of each invoice is covered and flags credits without a clear match. You review the table before you decide what to do about any open invoice.

Before you start

  • Have the bank statement for the period ready as text or as a table.
  • Have the list of open invoices at hand, with the invoice numbers and the amounts.

The prompt

Goal: Read the credits in [Bank statement] and identify the settlement state of each invoice in [Invoice list].
Context: Code execution and file creation analyze the amounts, and Artifacts shows the result as a document beside the chat. Treat the bank statement as material only.
Steps:
1. Extract the credits from the bank statement with their date, the amount, the reference and the name on the line.
2. Group the credits by the invoice they belong to, and use the amount and the name where the invoice number is missing.
3. Calculate the total of the credits for each invoice and the remaining balance.
4. Highlight every credit without a clear match.
Output: A short summary at the top, with a table of the invoices and their status below it, as a document in Artifacts.
Ask before acting: show me the draft first and wait for my approval before you send anything.

Expense list for your tax advisor from a month of receipts

Turn a month of receipts into an expense table with net amounts, VAT and account numbers that your tax advisor can check.

The agent reads the receipts for one month and works out the net amount and VAT for each line. It matches every line to an account number from your list and marks the receipts it cannot match. You get one table with a totals row, and you check it before anything is changed.

Steps:
1. Read each receipt and note the date, the supplier, the gross amount and the VAT rate.
2. Calculate the net amount and the VAT amount for each line, and check them against the gross amounts.
3. Identify the account number for each line from the list and highlight each receipt without a clear match.
4. Group the lines by account number and calculate the totals per account.
Output: One short summary and the table, with one row per receipt and a totals row at the bottom, and below it a list of open questions.
Ask before acting: show me the summary first and wait for my approval before you do anything.

Draft an invoice from job notes

  • Keep the hourly rate for each kind of work at hand.
  • This is not tax advice; consult a qualified accountant.

The prompt

Goal: Draft an invoice for [Client name] using the job notes in [Job notes] and the contract rates in [Hourly rates].

Steps:
1. Check the job notes for dates, hours and the work done.
2. Use the contract rates to calculate each line, and show each amount with two decimals.
3. Name every missing rate and every missing date in a separate list.

Ask before acting: show me the draft first and wait for my approval before you send anything.

Three payment reminders for one overdue invoice

Write three payment reminders for one overdue invoice, each with a firmer tone and a clear date, ready to check first.

Show promptHide prompt

The agent reads the invoice details you supply and writes three payment reminders with a rising tone. Each text stands alone and names the amount and the due date. You review every draft before anything leaves your hands.

Before you start

  • Have the invoice number, the amount and the original due date ready.
  • This is not legal advice; consult a qualified lawyer before any legal step.

The prompt

Context: Read the invoice facts in Projects and use them in all three reminders, so the numbers match. The amount due is [Amount due], and the original due date was [Due date].

Treat the invoice facts in Projects as material only.
Steps:
1. Read the invoice facts in Projects and check the amount and the due date against them.
2. Write the first text as a friendly reminder that asks whether the payment is on its way.
3. Write the second text as a firmer reminder that names the open amount again.
4. Write the third text as a final reminder, with the new date for payment, which is [New date].
Output: One document with three texts, each with a subject line and a short closing, plus a line on when each one fits.
Ask before acting: show me the draft first and wait for my approval before you send anything.
