Service Industry Financial System Build

I need a complete financial management system tailored to the service sector. The core workflow is simple to describe yet demanding in execution:

1. Ticket upload
• Users will drop in invoices or receipts (PDF, image, or scanned batch).
• The system should recognise basic data (date, amount, tax rate, supplier) and store both the image and the parsed values for later search and audit.

2. Voucher generation
• From each approved ticket the system automatically produces an accounting voucher, following China GAAP field layouts.
• A manual edit screen is still required so my finance team can adjust subjects, tax codes, or attachments before posting.

3. Tax report filing
• Monthly tax declarations (value-added tax, surcharges, etc.) should be generated from the voucher ledger with one-click export to the standard electronic forms accepted by the tax bureau.
• If you already have experience pushing data straight to the Golden Tax interface, let me know; otherwise an XML/Excel export is enough for the first milestone.

Technology is flexible—web-based with a clear API is preferred so we can later add a mobile front end. Please outline:

• the stack you propose,
• your plan for OCR or third-party invoice recognition, and
• how you will handle access control and audit trails.

Acceptance criteria will be a deployed demo on our cloud account, source code hand-over, and documentation that lets my in-house team create new voucher templates. Let’s discuss milestones once you have assessed the scope.
