Uku 360 Księgowość

Invoices

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.

  • Due date
360 Księgowość Uku
  • Clients

    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.

  • Articles & tax rates

    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).

  • Work volume data

    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.

  • Payment status

    When 360 Księgowość marks an invoice paid, Uku closes the loop on the same client.

    Automatic if enabled in billing settings.

Invoice export on demand · Payment status checked automatically · Re-sync clients any time.

FAQ

Questions about the 360 Księgowość integration

How do I connect 360 Księgowość?

Go to Uku App Store → 360 Księgowość → Activate. Enter your 360 Księgowość email and password. Uku auto-creates API keys for all clients. You need Admin or Manager permissions in Uku and a 360 Księgowość Pro or Premium plan.

Is client sync one-way or two-way?

One-way: 360 Księgowość → Uku. Customers, addresses and register codes flow into Uku. We deliberately don't push client edits back — your books stay the single source of truth.

What exactly flows between Uku and 360 Księgowość?

From 360 Księgowość → Uku: customers, articles, tax rates, units, resource codes, purchase and sales invoice counts, payment status. From Uku → 360 Księgowość: invoices, line items, VAT rates, due dates.

Can I bill per invoice count?

Yes. This is the killer feature: 360 Księgowość reports the number of sales and purchase invoices per client per month, and Uku uses that number to bill your volume-based contracts automatically.

Why can't I assign multiple VAT rates to one article?

In 360 Księgowość (and Merit Aktiva), each article is tied to a single VAT rate. If you need the same service at different VAT rates, create separate articles — e.g. AUDIT-23 and AUDIT-0.

Can I send pre-activation invoices to 360 Księgowość?

No. Only invoices created after the integration is activated can be exported. Invoices created before activation cannot be sent retroactively.

What if two-factor authentication blocks the import?

2FA on 360 Księgowość may prevent client import. Contact Uku support — we have workarounds to complete the connection.
