The Challenge
Business Problem
Employees spend hours filing expense reports. Finance teams spend even more time verifying receipts, checking policy compliance, and processing reimbursements.
The Approach
Solution Overview
Connect Gmail MCP Server with QuickBooks and Slack to create an automated expense processing pipeline: scan receipts, categorize expenses, check policy, route for approval.
Step-by-Step
Implementation Steps
1
Scan Receipts
Use OCR to extract data from receipt images: merchant, amount, date, category.
2
Auto-Categorize
Classify expenses into categories (travel, meals, software, office supplies) based on merchant and amount.
3
Check Policy Compliance
Verify expenses against company policy: per-diem limits, pre-approval requirements, receipt requirements.
async function processExpense(receipt) {
const data = await ocr.extractText({ image: receipt.image });
const expense = parseReceipt(data);
const policyCheck = checkPolicy(expense);
if (policyCheck.violations.length > 0) {
await slack.sendMessage({ channel: expense.submitter, text: `Expense flagged: ${policyCheck.violations.join(', ')}` });
} else {
await quickbooks.createExpense({ ...expense, status: 'pending_approval' });
}
}4
Route for Approval
Send compliant expenses to the appropriate manager for approval via Slack.

Policy Checker
function checkPolicy(expense) {
const violations = [];
if (expense.category === 'meals' && expense.amount > 75) violations.push('Meal exceeds $75 limit');
if (expense.category === 'travel' && !expense.preApproved) violations.push('Travel requires pre-approval');
return { violations, compliant: violations.length === 0 };
