Invoice processing in New Zealand
InvoiceHaven is an AI-powered invoice-to-data platform for New Zealand businesses: it turns PDF, scanned and photographed invoices into structured, reviewable Excel data.
A New Zealand business processes invoices in InvoiceHaven by uploading them, letting OCR and AI extraction capture the supplier, invoice number, dates, currency, subtotal, GST, total and line items, reviewing the flagged values, and exporting the result as an Excel workbook. The whole workflow is Upload → Extract → Review → Export.
Invoice data extraction
Extraction reads the OCR text and assigns each value to a named field, so an invoice arrives as rows rather than as a document to retype. The field-level detail lives on invoice data extraction, and the reading step is explained on what is invoice OCR.
NZD invoices and GST information
Currency
Currency is captured as a field, so NZD invoices are handled directly while invoices in other currencies are still processed.
GST
GST amounts are extracted and checked arithmetically against the subtotal and total. When an invoice has no GST amount, the check is reported as not applicable rather than as a pass. More detail on GST invoice processing in NZ.
Supplier and invoice details
- Supplier name.
- Invoice number.
- Invoice date and due date.
- Currency, subtotal, GST amount and total.
Line items
Line items are captured alongside the header fields and are included in the Excel export, so a multi-line supplier invoice does not collapse into a single total.
Validation checks
- Subtotal, GST and total are recalculated and invoices that do not add up are flagged.
- A missing GST amount is reported as not applicable rather than as a pass.
- Possible duplicate invoices are flagged for a closer look.
Manual review
Every extracted value stays editable on the Review screen. Flagged invoices are meant to be checked by a person, and the values you approve are the values that get exported.
Excel export
Select one or many reviewed invoices and export them as a multi-sheet Excel (.xlsx) workbook containing header fields and line items. See invoice to Excel and PDF invoice to Excel.
Workflow: Upload, Extract, Review, Export
- Upload — drag in PDF, JPG or PNG invoices, or photograph one with a phone camera.
- Extract — OCR reads the pages and AI extraction fills the invoice fields and line items.
- Review — check flagged values and correct anything that was misread.
- Export — download the selected invoices as an Excel workbook.
