Frequently Asked Questions
Will the App support future UJP e‑Faktura API endpoints?
Yes. The App is architected to quickly enable new UJP endpoints (e.g., status retrieval, inbound purchase invoices, corrections) as they become publicly available. No re‑implementation is required — features are activated via updates.
Do I need additional middleware or a separate tool?
No. Preparation, digital signing, submission, and monitoring of e‑invoices are performed directly inside Business Central. There’s no parallel portal work or manual uploads.
What if my company doesn’t use Business Central?
Use the Gateway Solutions: Shared On‑Prem, Dedicated Cloud, or Self‑Hosted — depending on your ERP, infrastructure, and governance policies. All of them run on the same LSM API engine.
Is the App aligned with the UJP e‑Faktura pilot and future phases?
Yes. The App supports outbound documents (sales invoices and credit memos) per the current phase and is ready to extend when UJP publishes additional functional areas.
What technical prerequisites are required?
You need a Business Central environment, a UJP‑accepted digital certificate, and the installation of LSM Reusables and LSM API Connector. These are part of our standard, proven component stack.
Can our finance team operate the process without IT involvement?
Yes. Finance works entirely in Business Central — viewing statuses, messages, and EUIDs; performing corrections; and reviewing logs. The process is designed to be operational, not technical.
