SDOS saves you time.
From creating an order to issuing an invoice — in under a minute.
For small business owners and small sales teams.
Real workflow
From order to invoice — in under a minute.
Customer → Order → Planner → Invoice
A new customer comes in — the card is already at hand.

The order is entered right away — products, quantities, prices.

The follow-up lands in the Planner with a deadline.

The invoice is built from the order data — print or PDF.

SDOS saves you time. Daily work gets done faster — so there is no more stitching your workflow together from Excel, notebooks, chats and scattered files.

Load products quickly and instantly see current stock levels.

A clear picture of your work and detailed reporting.
