Use AI for Invoicing & Admin
Turn hours of repetitive paperwork into minutes of prompting — invoices, receipts, expenses, email triage, and meeting summaries.
Why this matters
Admin tasks — drafting invoices, chasing receipts, categorising transactions, triaging email, summarising meetings — quietly eat hours every week. AI tools can draft, extract, categorise, and automate the repetitive parts, leaving you to do the review and judgement that matters.
Step 1. Drafting invoices
Give the AI the raw facts and ask for a formatted invoice.
Prompt
"Create an invoice for [service] to [client name] at [rate] for [hours]. Include bank details: [account]. Format as a professional invoice."
Copy the output into your template, verify the numbers, and send.
Step 2. Extracting data from receipts
Upload photos of receipts to ChatGPT or Claude. Ask it to extract: date, vendor, amount, category, tax. Request output as CSV so it drops straight into a spreadsheet.
Prompt
"From these receipt images, extract date, vendor, amount, category, and tax. Output as CSV."
Step 3. Categorising expenses
Paste a list of transactions and ask AI to sort into categories.
Prompt
"Categorise each of these transactions into one of: Travel, Office, Software, Meals, Other. Add a column for the category."
Useful for tax prep and monthly reviews.
Step 4. Email triage
Paste a summary of your inbox and ask AI to flag urgent items, draft responses for routine ones, and group the rest by action needed. Ask it to output as a table with columns: Sender, Subject, Category, Suggested Action, Draft Response.
Step 5. Meeting summaries
Upload a meeting transcript or rough notes. Ask AI to produce: action items (with owners), decisions made, follow-ups for next time. Format as a structured document you can share with attendees.
Step 6. Integration with tools
Once your prompts are reliable, wire them into your stack.
- •Connect AI to spreadsheets via Zapier or n8n.
- •Bulk process a folder of receipts.
- •Automate recurring invoices on a schedule.
- •Start simple, automate gradually.
Quick Tips
- •Keep a library of prompt templates for common tasks.
- •Always verify financial figures before sending.
- •Don't send AI-drafted invoices unreviewed.
- •Reconcile AI output against bank statements.
- •Start with one workflow and expand once it's reliable.
