Integrated Financial Reporting Platform

I need a finance-grade reporting system that plugs straight into the major accounting suites my team already uses (QuickBooks, Xero, NetSuite are the initial priorities). The platform should pull ledger data automatically, map it to our chart of accounts, and present consolidated statements without forcing users to export and re-upload files.

Seamless integration is the centerpiece of this build; if the connection layer works flawlessly the rest of the workflow becomes simple. Real-time dashboards and highly customizable layouts are on the horizon, so an architecture that leaves room for those modules is appreciated, but phase one is all about dependable synchronisation and clean, verifiable outputs.

For delivery I expect:
• Production-ready code with clear setup instructions
• A short technical note that documents the integration method (API endpoints, auth flow, data model)
• A working demo environment showing live data pulled from at least one accounting package

If you have previous experience building finance or accounting integrations, especially around journal data, that will help us move fast. Let me know which stacks you prefer and how you would secure data in transit and at rest.
