Sound familiar?

A good system that does not talk to KSeF costs you time and control.

You have your own system

You use tailor-made software or an old ERP that has worked for years, and you have no intention of changing it.

KSeF passes you by

Your system does not support KSeF. You send invoices to the accounting firm by hand or look for makeshift workarounds.

You lose time and control

Employees send documents by email, invoices get lost, and you have no up-to-date view of costs and receivables.

Our solution

A dedicated microservice: a bridge between your system and KSeF

We build a dedicated microservice that integrates your system with Administy. Administy handles all communication with KSeF, the document flow, cost approval and passing data to the accounting firm.

You do not change your system. We give it the wings it lacks.

  • Communication with KSeF handled on the Administy side
  • Document flow and cost approval
  • Passing data to the accounting firm
Document flow

How does the integration work?

Two scenarios, one goal: full automation with no manual sending of documents.

1

Domestic invoices (from KSeF)

No foreign invoices: the whole flow goes through KSeF.

  1. Your system (ERP / legacy)
  2. Microservice integrating the system with Administy
  3. Administy
  4. Sending invoices to KSeF
    Downloading cost documents from KSeF
  5. The accounting firm downloads documents from KSeF
2

Domestic + foreign invoices

Administy consolidates documents from KSeF and foreign invoices (OCR) in one place.

  1. Your system (ERP / legacy)
  2. Microservice integrating the system with Administy
  3. Administy
  4. Downloading documents from KSeF
    Foreign invoices added via OCR and sent to KSeF
  5. The accounting firm downloads documents from Administy

In both scenarios no document reaches the accounting firm by hand. The flow is fully automated by Administy.

Bonus

Your system gets wings

By integrating with Administy, your system gains access to all the platform's features, with no rewriting or migration.

Who it is for

Who is this solution for?

Companies with their own ERP system

Do you have tailor-made software? We build a microservice that links it to Administy and KSeF, with no data migration.

Accounting firms

Do you serve many clients? Administy automatically pulls data from KSeF and delivers it in a ready form. You focus on advisory work.

Companies with foreign invoices

Lots of foreign costs? Administy consolidates them with data from KSeF and passes them to the accounting firm in one place.

Capital groups and holdings

Many companies, different systems? We build a microservice architecture for the whole group with a single KSeF integration point.
