FinFlow Finance Suite

A painting and construction services company generating $3.2M in annual revenue was running its entire financial operation on spreadsheets, paper invoices, and a bookkeeper who worked 3 days a week. Cash flow was unpredictable, invoicing was slow, and the owner spent 12+ hours per month chasing overdue payments instead of running the business.

Invoices were created manually in Word, saved as PDFs, and emailed individually. Average time from job completion to invoice sent: 6 business days. Some jobs went 3+ weeks before invoicing

28% of invoices were overdue at any given time. Follow-up was manual: the bookkeeper checked a spreadsheet, identified overdue accounts, and sent individual reminder emails. No escalation logic, no automation

Expense tracking lived in a shoebox of receipts and a monthly spreadsheet reconciliation. The bookkeeper spent 2 full days per month categorizing expenses from bank statements and receipt photos

Cash flow forecasting didn't exist. The owner checked the bank balance daily and made spending decisions based on what was in the account, not what was coming in or going out

Financial reporting was a quarterly event. The bookkeeper compiled P&L and cash flow statements manually. Reports arrived 3-4 weeks after quarter end, too late to act on

Tax preparation required 2 weeks of scrambling to organize receipts, reconcile accounts, and produce reports the accountant could work with

The business was profitable but financially blind. Every dollar decision was reactive instead of planned.

I built a financial operations platform that automates invoicing, tracks expenses in real time, forecasts cash flow, and delivers financial reporting on demand. Designed so the business owner gets a clear financial picture without waiting for the bookkeeper.

Job done → invoice sent. Same day. Every time.

✅ Scenario modeling: "what if Client X pays 2 weeks late?" or "what if we hire another crew?" with instant impact visualization

✅ Low-balance alerts triggered when projected cash flow drops below configurable thresholds

📊 Outcome: Owner went from checking bank balance daily to reviewing a cash flow forecast weekly. Caught a projected $45K shortfall 6 weeks in advance, allowing proactive invoice acceleration

Quarterly scramble replaced with real-time visibility.

✅ Auto-generated P&L, cash flow statements, and balance sheets pulling from live transaction data

✅ Tax-ready export packages with categorized expenses, income summaries, and receipt archives organized by quarter

✅ Configurable dashboards for the owner (high-level health metrics) and the bookkeeper (transaction-level detail)

📊 Outcome: Quarterly reporting from 3-4 week delay to instant generation. Tax preparation time reduced from 2 weeks to 2 hours. Accountant fees dropped 30% due to cleaner, pre-organized data

Why I chose this stack and what tradeoffs I made.

PostgreSQL with double-entry ledger schema — Financial data demands audit trails and balance integrity. Every transaction records as a debit-credit pair with immutable entries. Corrections create new entries rather than modifying existing ones. This adds storage overhead but eliminates reconciliation errors

Stripe for payment processing over direct bank integration — Card and bank transfer acceptance with automatic reconciliation. Stripe's webhook-driven payment confirmation eliminates polling and ensures invoice status updates within seconds of payment

AWS Lambda for OCR processing — Receipt scanning is bursty (most uploads happen Monday mornings). Lambda scales to handle 50 concurrent uploads during peak and costs nothing during quiet periods. Textract handles OCR with 94%+ accuracy on printed receipts

Next.js for the owner dashboard — The business owner checks financials on mobile between job sites. Server-rendered dashboard with responsive layout loads in under 2 seconds on 4G. Critical metrics visible without scrolling
