Amina used to spend the first two days of every month chasing down client payments in a spreadsheet, manually coloring rows and rebuilding reports for her accountant. She often missed small outstanding balances because the data lived in too many places.

With BillPulse, she uploads bills, marks payment status, and generates a polished monthly PDF in minutes. The report clearly separates paid and unpaid bills, calculates outstanding amounts automatically, and syncs to Google Sheets, giving her a cleaner close process and a more professional client-facing record.

Technical Needs

  • Frontend built with Next.js and TypeScript for fast interactive tables and report preview.
  • Backend API using Node.js with NestJS or Express for billing records, reporting, and sync orchestration.
  • PostgreSQL for relational storage of clients, bills, payment statuses, and audit logs.
  • Background jobs with BullMQ and Redis for PDF generation and Google Sheets sync retries.
  • PDF rendering service using Playwright or Puppeteer to generate pixel-consistent branded reports.
  • File storage on AWS S3 or equivalent for generated PDFs and uploaded CSVs.
  • Authentication with secure session handling and role-based access control.

Integration Points

  • Google Sheets API via Google OAuth
  • Google Drive API for report file storage or optional export
  • Email delivery via SendGrid or Postmark
  • Auth via Google Sign-In and email magic links
  • Optional Stripe billing for product subscriptions

Data Storage & Privacy

  • Store client bill data in a tenant-isolated schema or tenant_id partitioned model.
  • Encrypt sensitive fields and all files at rest using managed cloud encryption.
  • Use TLS 1.2+ in transit for all client, API, and integration traffic.
  • Provide data export and deletion workflows to support GDPR and CCPA requests.
  • Keep an audit log of changes to payment status, exports, and sync actions for compliance and debugging.

Scalability & Performance

  • Support asynchronous report generation so dashboard interactions remain responsive.
  • Cache monthly summary aggregates to avoid repeated table scans on every dashboard load.
  • Design bulk imports to process at least 10,000 rows per workspace without timeouts.
  • Use queue-based retries and rate limiting for third-party sync APIs to avoid integration failures.

Potential Challenges

  • CSV imports may have inconsistent column formats; mitigate with column mapping and preview validation before commit.
  • Users may expect automatic bank reconciliation; mitigate by clearly scoping this as bill tracking and status reporting, not bank feed matching.
  • PDF branding can break layout with long client names; mitigate with responsive table truncation, wrapping rules, and multi-page pagination.
  • Google Sheets sync may fail due to revoked permissions or rate limits; mitigate with re-auth prompts, retries, and clear sync status indicators.
  • Multi-currency and partial payments can create calculation confusion; mitigate by showing explicit currency labels, outstanding formulas, and immutable originals in the audit log.

1. Authentication and workspace setup with company name, logo upload, and default currency
2. Dashboard with month filter, totals cards, client table, status chips, overdue highlights, and quick actions
3. Bill create/edit modal and CSV import flow with column mapping and validation preview
4. Monthly report builder with report preview and PDF generation/download
5. Google Sheets connect screen with OAuth, spreadsheet selection, and sync history
6. Audit log and report history screens

Data model:
Workspace: id, name, logo_url, default_currency, created_at
User: id, workspace_id, name, email, role
Client: id, workspace_id, name, contact_email, notes

Report: id, workspace_id, month, pdf_url, totals_json, created_at, created_by
SyncJob: id, workspace_id, provider, spreadsheet_id, status, error_message, created_at
AuditLog: id, workspace_id, entity_type, entity_id, action, before_json, after_json, actor_id, created_at

Build with Next.js 14, TypeScript, Tailwind CSS, shadcn/ui, PostgreSQL, Prisma, NextAuth, Redis, BullMQ, and Playwright/Puppeteer for PDF generation. Use S3-compatible storage for uploads and generated PDFs. Use Google Sheets API with Google OAuth. Add server actions or API routes for CRUD, background jobs for PDF and sync tasks, and optimistic UI for inline edits.

Important behaviors:
Support single and bulk CSV import with mapping and validation errors.
Generate monthly PDF asynchronously and show progress/loading states.
Calculate totals for paid, unpaid, partially paid, and outstanding amounts automatically.
Preserve edit history in an audit log.
Make the UI look premium with strong typography, spacious tables, elegant status badges, and a polished PDF template that matches the app branding.
