Core Workflows
Workflow 1: Expense Capture & Recording
Document expenses accurately and consistently
- Required Information
- Date: When the expense occurred (transaction date) - Amount: Total amount spent (including tax) - Vendor/Payee: Who was paid - Category: Type of expense (see categorization below) - Payment Method: Cash, credit card, check, ACH - Description: What was purchased and business purpose - Receipt: Photo or PDF attachment
- Capture Methods
- Manual Entry: Key in details from receipt - Receipt Scanning: Photo → auto-extract data - Credit Card Import: Connect accounts for auto-sync - Email Forwarding: Forward receipts to expense email - Mobile App: Capture on-the-go
- Best Practices
- Record expenses within 24-48 hours (while fresh) - Always save receipts (digital or physical) - Note business purpose for tax deductibility - Flag personal expenses mixed in business accounts - Batch similar expenses (e.g., weekly mileage)
Workflow 2: Expense Categorization
Organize spending into meaningful categories
- Standard Categories
- Cost of Goods Sold (COGS): Direct costs of products/services sold - Materials, inventory purchases - Manufacturing costs - Shipping/fulfillment - Operating Expenses: - Salaries & Wages: Employee compensation, contractors - Rent: Office, warehouse, retail space - Utilities: Electric, water, internet, phone - Marketing & Advertising: Ads, campaigns, events - Software & Subscriptions: SaaS tools, licenses - Office Supplies: Stationery, equipment, furniture - Travel & Entertainment: Business travel, client meals - Professional Services: Legal, accounting, consulting - Insurance: Liability, property, health - Taxes & Licenses: Business taxes, permits, fees - Depreciation: Asset depreciation (non-cash) - Miscellaneous: Other operating costs
- Categorization Rules
- Use consistent categories across all periods - Create sub-categories for detailed tracking (e.g., Marketing > Facebook Ads) - Map credit card descriptions to categories automatically - Review and recategorize monthly for accuracy - Document category definitions for team clarity
- Tax Deductibility Flags
- Mark expenses as deductible, non-deductible, or partial - Track personal vs. business use percentage - Document business purpose for audit defense - Separate capital expenses (assets) from operating expenses
Workflow 3: Budget Management
Set spending limits and monitor against budget
- Budget Creation
- Set budgets by category and time period (monthly, quarterly, annual) - Base on historical spending + growth plans - Align with revenue projections and cash flow - Build in contingency buffer (5-10%)
- Budget Tracking
- Compare actual vs. budget by category - Calculate variance: (Actual - Budget) / Budget - Identify over-budget categories early - Forecast end-of-period spending based on run rate
- Budget Alerts
- Set thresholds for alerts (e.g., 80% of budget spent) - Notify stakeholders of overages - Require approval for over-budget purchases - Review and adjust budgets quarterly
- Flexible Budgeting
- Adjust budgets for variable costs tied to revenue - Example: Marketing budget = 20% of revenue - Automatically scale up/down with business performance
Workflow 4: Expense Reporting & Analysis
Generate reports for decision-making and compliance
- Standard Reports
- Expense by Category: Total and % of total for each category - Expense Trends: Month-over-month, year-over-year comparisons - Budget Variance: Actual vs. budget by category - Vendor Spending: Total spend by vendor (find savings opportunities) - Expense by Project/Department: Track cost centers - Tax Deduction Summary: Total deductible expenses for tax prep
- Time-Based Analysis
- Daily: Track daily burn rate - Weekly: Review team expenses, flag anomalies - Monthly: Close books, reconcile accounts, analyze trends - Quarterly: Budget reviews, forecast adjustments - Annual: Tax preparation, year-end reporting
- Cost Optimization
- Identify top expense categories (80/20 rule) - Find duplicate subscriptions or unused services - Negotiate vendor contracts for high-spend categories - Benchmark spending vs. industry standards - Track cost per customer/revenue metrics
Workflow 5: Reimbursement & Approval
Manage employee expense reimbursements
- Expense Submission
- Employee submits expense report with receipts - Categorizes expenses per company policy - Notes business purpose and attendees (for meals) - Submits for manager approval
- Approval Workflow
- Manager reviews for policy compliance - Checks receipt accuracy and business purpose - Approves, rejects, or requests clarification - Finance validates and processes payment
- Reimbursement Processing
- Set payment schedule (weekly, bi-weekly) - Pay via payroll, direct deposit, or check - Track reimbursement status (submitted → approved → paid) - Provide payment confirmation to employee
- Expense Policy Enforcement
- Define spending limits by category and role - Require pre-approval for large expenses - Specify allowed expense types - Set receipt requirements ($25+ threshold common) - Establish timely submission rules (within 30 days)

- Burn rate (monthly cash out)
- Runway (months of cash at current burn rate)
Budget Metrics:

- Budget utilization rate (% of budget spent)
- Forecast vs. actual variance
Efficiency Metrics:
