Features
Every Hong Kong document type, read in detail
From handwritten 銷售單 to IRD forms and cashier orders, InvHelper classifies and extracts with the detail audit and tax work need.

Bilingual receipt & invoice OCR
Chinese, English and mixed documents, including handwritten invoices and delivery notes.
Government & bank documents
IRD, Companies Registry and MPF forms by form code; BR vs. BR renewal demand notes; statements and advices by bank and purpose.
Cheques & cashier orders
Payee, cheque number, bank and amount in figures and words.
E-wallet & FPS records
Octopus, FPS, AlipayHK, WeChat Pay and delivery-app orders — without confusing a payment line on a shop receipt for an e-wallet receipt.
Multi-slip splitting
Several receipts on one page are counted, cropped and checked so none is lost or merged.
Content-based duplicate detection
The same file uploaded twice under different names is flagged before it reaches your ledger.
Transaction chains
Invoices, delivery notes, cheques and payments grouped into one transaction with billed, received and outstanding amounts.
Review queues
Unclassified, unmatched and split documents each have their own queue so nothing slips through.
Excel ledger export
One flat, chronological sheet with the source file on every row, plus per-issuer exports.
Built for volume
Background processing handles 500 to 5,000 documents per company and keeps running after you close the browser.
Search everything
Find any document by amount, text, invoice number or file name.
Traceable corrections
Edit any extracted value inline; your corrections stay attached to the document.
