Your data stays yours
Everything lives in one database file on your own computer, which you can copy, keep on an external drive or take with you. Your data doesn't sit with any outside vendor.
FOR BUSINESSES THAT MAKE OR SELL GOODS
Quotes, invoices and stock in one place. On your own computer.
From quote to delivery note and invoice, with inventory, purchasing and production in the same program. It runs on one Windows PC; your team opens it in a browser.

WHY SVALOG
Your business, your computer, your rules.
One install, whole team
Install Svalog on one Windows PC. Everyone else just opens a browser on the office network - phones, tablets, laptops. Up to ~20 people, nothing to install on their machines.
Only the modules you need
Sales, purchasing, manufacturing, accounting, analytics - each is a module you can switch on or off. Start with invoicing, grow into production planning when you're ready.
FROM QUOTE TO CASH
The paperwork handles itself.
01
Quote → Order
Send a quote, and when the customer says yes, one click turns it into a sales order - with stock reserved automatically so you never promise what you don't have.
02
Ship & Invoice
Shipping creates the delivery note, books the stock out, and writes the invoice in a single step. Partial shipments included.
03
Payments and e-invoices
Record payments and keep an eye on overdue invoices from the dashboard. For every invoice, Svalog creates an e-invoice in the EN 16931 / e-SLOG 2.0 format.
04
Month-end in one ZIP
At the end of the period, Svalog bundles every PDF, e-invoice XML and CSV summary into one ZIP and emails it straight to your accountant.
MODULES
Switch on what your business needs.
Every business domain in Svalog is an installable module. Enable them from the built-in marketplace - each one adds its own pages, documents and reports.
Free
Sales
Customers, quotes, sales orders, delivery notes, invoices, credit notes and payments. The complete quote-to-cash chain.
Free
Purchasing
Suppliers, purchase orders and goods receipts. Approve a PO, receive the goods, and stock updates itself.
Free
Inventory & Products
Product catalogue, stock levels and a full movement ledger so every quantity can be traced to a document.
Temporarily free
Manufacturing
Bills of materials, production orders and units of measure. Consume components, output finished goods, scrap factored in.
Temporarily free
Analytics
Sales, purchasing, inventory and production reports, plus AR/AP aging so you always know who owes whom.
Free
Accounting
VAT summaries, profit & loss, period locking and the one-ZIP export your accountant will thank you for.
HOW IT WORKS
Up and running before the coffee gets cold.
- 1
Install on one Windows PC
Run the installer on any Windows computer in your office. Svalog sits quietly in the system tray and starts with the machine.
- 2
Open a browser
Everyone on your network goes to the Svalog address. The setup wizard walks you through company details, your logo, and the first user account.
- 3
Send your first quote
Add a customer and a product, hit Send. That's the whole onboarding.
BUILT RESPONSIBLY
Small app. Serious foundations.
Roles & permissions
Admin, manager and staff roles keep settings, prices and documents in the right hands.
Audit trail
Every create, change and status switch is logged with who and when.
Automatic backups
Automatic database backups to a folder you choose (a NAS, a USB drive, anywhere).
Signed modules
Every module is cryptographically signed; Svalog refuses to load tampered code.
Immutable stock ledger
Stock history is append-only. Quantities always add up, and you can prove it.
Works offline
No internet? No problem. Svalog runs on your LAN; the internet is only needed for email and updates.
PRICING
Start free. Pay only for what grows.
What you pay depends on how many people and which modules you use. Three rules:
- 1
The core is free forever.
One user, full quote-to-cash: products, inventory, customers, quotes, orders, delivery notes, invoices, purchasing and accounting export. A complete one-person business runs on €0.
- 2
Extra users are free for now.
Each additional user will be €12 per year. While we're getting started, you can add them for free, with no limit on how many.
- 3
Paid modules are a one-time purchase.
Buy them when your business needs them, and they're yours for good. The core always stays free.
QUESTIONS
Frequently asked.
Is it really free?
Yes - for one user with the core modules, free forever, no trial clock. Adding users will cost €12/year each (free for now while we're getting started), and some modules are one-time purchases - but the core always stays free.
Do I need a server?
No. Any reasonably modern Windows PC works - the one at the front desk is fine. Svalog runs in the background and uses very little memory.
Does it work on Mac, Linux, tablets or phones?
Svalog itself installs on one Windows PC. After that, any device on the same network - a Mac, a Linux machine, a tablet or a phone - can use it through a web browser. There's nothing to install on those devices; you just open Svalog's address in the browser.
How many people can use it?
Svalog is designed for teams of up to about 20 people using it at the same time over a local network.
Is my data in the cloud?
No. Everything is stored in a single database file on your PC, in a folder you choose. Svalog works entirely on your local network.
What about backups?
Svalog backs up the database automatically to a folder you pick - a NAS or an external drive is ideal. Restoring is copying one file.
Can I use it in Slovenian?
Yes. The whole app - including its PDF documents - is available in English and Slovenian. Invoices, quotes and other documents print in the language set for your company, with Slovenian number and date formats, and e-invoices use the Slovenian e-SLOG 2.0 format.
Does Svalog create e-invoices?
Svalog generates structured e-invoices to the EN 16931 European standard and the Slovenian e-SLOG 2.0 format, and your accountant gets a clean period export (PDF, XML and CSV). Sending e-invoices through an e-invoice provider or the Peppol network - mandatory between Slovenian businesses from 1 January 2028 - is not built in yet.
What if I outgrow it?
Your data is a standard SQLite database and every list exports to CSV. There is no lock-in - migrating away is as easy as migrating in.
Can it do something specific to my business?
Possibly already - check the module marketplace. If not, the module SDK lets any developer extend Svalog with new pages, documents and logic.
