ORAAccounting deserves better tools.

A Mac and Windows application connecting documents, accounting modules and an AI assistant, with verifiable results.

My role: Independent developer and technical lead
Context: Since 4 October 2026 · in production, with ongoing development

ORA application: accounting module catalogue in the staging environment — ORA application v1.193, staging environment, October 2026. Screenshots supplied for this contribution, using demonstration data.

The starting point

Accounting firms work with documents, spreadsheets and sensitive data every day. ORA brings these workflows together to reduce manual re-entry and prepare analysis while keeping people in control of the results.

What I took responsibility for

I took over an existing application to improve reliability, secure its operation and continue development. My scope covers the application, backend, data, infrastructure, tests and releases. I also translate needs, prioritise work and integrate the project owners’ business modules.

Inside the application

Staging screens with demonstration data. Open any screenshot to see it at full size.

ORA bank statement settings using a demonstration FEC file — Prepare processing: journal, bank account and suspense account, with settings validated by the user.

ORA demonstration bank statement result and Excel export — Check movements and totals before downloading the Excel workbook. Displayed amounts are fictional.

ORA Atlas demonstration company folder, documents and access management — Atlas: organise files by company and financial year, with private or shared access.

ORA demonstration balance sheet with document assistant and source page references — Read and question a document in the same interface, with answers linked to source pages.

The decisions that matter

AI with sources you can check
The assistant answers from documents and exposes the passages and pages used. Pseudonymisation reduces identifying data sent to models, without promising perfect anonymisation.
Processing you can verify
PDF bank statements to Excel, amount checks, reconciliation and regression tests. An FEC file can help suggest accounts; users still validate the settings.
Reliability beyond the interface
Access isolation between firms, independent encrypted backups, restoration tests, separate staging and production environments, installers and signed Mac packages.

What the project demonstrates

A production application I help evolve across its technical layers, with continuous attention to data, processing and releases.

Under the hood

To be precise

Technical takeover and evolution. Business modules are developed with the project owners; I do not claim sole authorship.
