Local invoice data entry, no cloud

Read a whole folder of invoices - PDFs, scans, photos - and fill in an accounting table on-device, free and offline.

quick-start.sh

git clone https://github.com/tetherto/qvac-examples
cd qvac-examples/qvac-invoice-manager-demo
npm install
npm start

QVAC Invoice Manager is an illustrative example that reads a folder of invoices and fills in an accounting table, entirely on-device and for free. Point it at a hierarchy like 2026/<supplier>/ and it works through PDFs, scans, and photos with the right reader for each, flags fields it is unsure about, checks that net + tax equals total, and exports a CSV with European semicolon formatting - without uploading a single document anywhere.

Prerequisites

Node.js 22.17 or later
8 GB RAM minimum for one model, 16 GB+ recommended
~2.5 GB disk for the text model, ~1.6 GB for the vision model
Apple Silicon (Metal) or a Vulkan GPU preferred - CPU works, just slower
A folder of supplier invoices to test with (or use the samples in demo/)

Before downloading any models, run the QVAC diagnostic tool to confirm your RAM, disk space, and GPU support are sufficient.

doctor.sh

npx -y @qvac/cli doctor

Clone qvac-examples and install the invoice-manager-demo package. This pulls in the QVAC SDK and the local text/vision models it needs.

setup.sh

git clone https://github.com/tetherto/qvac-examples
cd qvac-examples/qvac-invoice-manager-demo
npm install

npm start launches the app. Select a folder such as 2026/<supplier>/ - QVAC Invoice Manager walks the whole hierarchy and chooses a text or vision reader per file, so PDFs, scans, and photos are all handled in the same pass. No invoices yet? Sample documents ship in demo/.

start.sh

npm start

Final result

Folder of invoices scanned, with a text or vision reader applied per file
Custom accounting columns populated with extracted values
Low-confidence fields flagged, net + tax vs. total validated automatically
Table exported to CSV with European semicolon formatting
Nothing uploaded - every document stayed on the machine it started on

QVAC Invoice Manager is an illustrative example, not a product - it is not an accounting, bookkeeping, or tax tool, and a local model will misread some documents. Fork it from github.com/tetherto/qvac-examples and swap in your own columns, readers, or export format.
