Uku finds the 15–30% of revenue your 360 Księgowość invoice can't see.
Your team tracks the work. Uku turns it into invoices 360 Księgowość gets the same day. No spreadsheets, no missed minutes, no end-of-month panic.
360 Księgowość holds the books. Uku runs the practice. Here's exactly what moves between them — and which way. No black boxes.
Uku → 360 Księgowość
Your team's tracked time and contracts become invoices in Uku. Review, approve, and they land inside 360 Księgowość — header, line items, VAT, due date.
360 Księgowość → Uku
Every 360 Księgowość customer lands in Uku via API. Uku auto-creates API keys for each client on activation.
Clients with mismatched register codes are imported but flagged for review.
360 Księgowość → Uku
Your 360 Księgowość products become Uku billing templates — articles, VAT rates, units and resource codes.
Each article is tied to one VAT rate. Create separate articles per rate (e.g. AUDIT-23, AUDIT-0).
360 Księgowość → Uku
Uku auto-imports the actual volume of work per client — documents, entries, sales and purchase invoices, bank entries, VAT entries, and more. One interactive report, no switching between clients.
Imports actual entry counts for last month, including changes inserted into previous periods.
360 Księgowość → Uku
When 360 Księgowość marks an invoice paid, Uku closes the loop on the same client.
Automatic if enabled in billing settings.
