What the app covers
Business administration without scattering the work.
MyCompany is a Windows application for people who want client records, invoices, credit invoices, purchase invoices, article numbers, financial visibility, backups, migration continuity, and accountant-ready export in one local-first workspace.
See what needs attention first
The home overview surfaces unpaid totals, overdue work, monthly revenue, purchases, net balance, and reporting exports from one place.
Create, duplicate, export, and follow up faster
Sales and purchase invoice managers use grouped toolbars, clearer payment actions, CSV export, date filters, and duplicate flows for repeated work.
Review open payment items deliberately
The payment overview focuses on open invoices and purchase invoices, making paid items quiet and upcoming or overdue items easier to act on.
Move toward professional invoice documents safely
A next-generation PDF export path adds cleaner layout, branding, payment instructions, language support, and Dutch margin/VAT arrangement handling behind a fallback setting.
Use your own logo, color, and company identity
Users can configure company details, choose a branded accent color, and upload a logo so the application and exported invoice documents feel like their own business environment rather than a generic template.
Protect data before risky work
Settings now include a manual JSON backup entry, while migration prompts and archive pages keep older data paths understandable.
Use the app in the mode and language that fits
Dark and light themes, branded control color, restart prompts, and five languages are part of the daily app experience instead of hidden extras.
Feature detail
What the current release actually gives a small business operator.
The product is strongest when it is explained as a working desktop environment instead of a short feature list. These are the main surfaces and why they matter in daily use.
Client and article management
Client records and article numbers stay available inside the same workspace shell as invoicing. That keeps addresses, VAT-related details, standard descriptions, and reusable items close to the document workflows instead of pushing them into a separate external system.
Sales and purchase document handling
Sales invoices and purchase invoices each have their own managers, but they follow the same visual rhythm. Users can add, edit, duplicate, save, export to PDF or CSV, review due dates, and change payment state without relearning the workspace.
Credit invoices as a first-class workspace
Version 7.0 adds a dedicated credit invoice manager. Users can create a corrective document from an existing paid invoice or create one manually, keep it in the same local archive, and export it with the same PDF flow as the rest of the document family.
Operational overview instead of a decorative home screen
The home view is not a landing page. It is where users see open totals, overdue work, purchase exposure, balance context, trend charts, and report exports so the next action is obvious before they open a manager.
Client account context during follow-up
The client workflow is not limited to address data. The app can now surface account-style context such as open invoices, overdue exposure, paid history, and recent activity, which makes the client workspace more useful during real contact moments.
Follow-up and review support
Due state and payment state are kept separate. That means users can tell the difference between an invoice that is paid, an invoice that is still open but on time, and one that needs attention because it is approaching or past the due date.
Document output with branding and language support
The PDF path is moving toward more professional invoice layout while keeping a fallback path available. Branding, language support, payment instructions, and Dutch VAT-margin behavior can be handled without forcing risky one-way changes on existing users.
Branding and company identity across the app
MyCompany is not limited to storing invoices. Users can configure company details, upload their own logo, and choose a branded control color so the application shell and generated documents reflect the business they are actually running.
Local control, backup, and migration continuity
Backups, archive context, and migration visibility are treated as product features rather than afterthoughts. Users can create a backup before risky changes and keep confidence that older installs and datasets still have a visible route forward.
Backup, restore, migration, and accountant export
Data management in 7.0 is more explicit. Users can create a local backup, restore a compatible backup, migrate an older dataset, and prepare an accountant export package without dropping into technical folders or external helper tools.
What changed in 8.0.0.0
A productivity and modernization release on top of the 7.x foundation.
Version 8.0 keeps the calm 7.x workflow and business cockpit, then adds professional productivity features: comprehensive undo/redo, one-click email delivery, multilingual support in 5 languages, .NET 10 modern framework, and zero-warning quality.
1
Undo/Redo brought safety to invoice editing
Full Ctrl+Z and Ctrl+Y support across all invoice item editing with a 401-test-proven implementation, 50-action stack, and smart change tracking. Mistakes are now one keystroke away from being undone.
2
Email integration and multilingual support opened new markets
One-click email delivery with auto-generated PDF attachments, plus full UI localization in English, Dutch, German, French, and Spanish with runtime switching. The app is now globally accessible.
3
.NET 10 migration brought modern foundation and professional polish
Complete migration to .NET 10, MVVM Toolkit adoption, zero compiler warnings, DataGrid perfection across all 7 grids, and consistent dark/light theme support throughout the application.

Ready to install the current release?
Version 7.0.0.0 is the recommended release. Version 6.1.0.0 remains on the site as the previous stable line, while 6.0.0.0 stays available for archive and fallback context.
The current installer is built for Windows 10 and Windows 11 on x64 systems. If the required .NET 10 desktop runtime is not already present, the installer handles that dependency path automatically.
