Expense Report Generator: Receipts In, Reports Out
Forward receipts as they happen and get a polished expense report with categories and totals when you need it.
What You Will Get
Expense reporting is one of those tasks that is simple in theory and miserable in practice. You stuff receipts in a folder, forget about them for three weeks, then spend a painful evening squinting at crumpled paper trying to remember what that $47.82 charge was for. Tax season makes it worse.
With this setup, you forward receipt emails or snap photos of paper receipts and send them to your agent on WhatsApp or Telegram throughout the month. The agent extracts the vendor name, amount, date, and category (meals, travel, software, office supplies) and logs everything. At month-end — or whenever you ask — it generates a formatted expense report with line items, category subtotals, and a grand total.
The report is clean enough to hand to your bookkeeper or attach to a reimbursement request. No more end-of-month receipt archaeology. Setup takes about 10 minutes and the ongoing effort is literally just forwarding emails as they arrive.
Setup Steps
Get your expense pipeline running in about 10 minutes.
Enable Gmail Access with gog
Connect the gog skill to your Gmail so the agent can read forwarded receipt emails. This lets it extract amounts, dates, and vendor names directly from email bodies and attachments.
Define Your Expense Categories
Message your agent: 'My expense categories are: Meals & Entertainment, Travel & Transport, Software & Subscriptions, Office Supplies, Professional Services, and Miscellaneous. Categorize each receipt into one of these.'
Set Up the Forwarding Workflow
When you get a receipt email, forward it to your agent's email trigger or paste the details into WhatsApp. For paper receipts, snap a photo and send it with a message like '$24.50 lunch with client, March 12.'
Configure the Report Format
Tell the agent how you want the final report: 'At the end of each month, compile all expenses into a report sorted by category. Include date, vendor, amount, and category for each item. Show subtotals per category and a grand total at the bottom.'
Test with Recent Receipts
Forward five recent receipt emails and then ask: 'Show me my expenses so far this month.' Verify the categories and amounts are correct. Adjust the categorization rules if the agent misfiles anything.
Set a Monthly Reminder
Schedule the agent to send you a complete expense report on the last day of each month. Add a mid-month check-in too — 'Send me expense totals so far on the 15th' — so you can catch any missing receipts early.

Tips and Best Practices
Forward Immediately
The moment a receipt hits your inbox, forward it. This takes 3 seconds and eliminates the end-of-month scramble entirely. Build the habit and it becomes automatic.
Use a Consistent Format for Manual Entries
For cash purchases, stick to a simple format: '$[amount] [what] [when]'. Example: '$15.50 parking downtown March 14.' This makes extraction reliable.
Review Categories Monthly
Check the mid-month summary for miscategorized items. Correcting the agent early means it gets more accurate over time as you refine the rules.
Export for Your Accountant
Ask the agent to format the report as a CSV-friendly table. Your bookkeeper can drop it straight into their accounting software.
