ERPNext Implementation & Support Across Poland
Polish manufacturers have just absorbed KSeF, mandatory for all B2B invoicing since April 2026, and they compete on precision and price against suppliers across Europe. Per-user ERP licensing works directly against that advantage. Sigzen, a certified ERPNext and Frappe partner, implements ERPNext with KSeF connected so invoices flow from the order record, full production depth for aerospace and automotive supply, and open-source licensing that keeps software cost fixed as the team grows.

Why Polish manufacturers work with Sigzen on ERPNext
Small and mid-size manufacturers in Polish are caught between ERP systems priced for corporations and accounting software that stops at the office door. ERPNext closes that gap with full production depth and open-source licensing. Sigzen, a certified ERPNext and Frappe partner, implements it with the local compliance layer built in and working hours that overlap the European day.
Operating with KSeF already mandatory
KSeF became mandatory for large taxpayers in February 2026 and for all B2B transactions from April 2026, with the smallest businesses following in January 2027. Sigzen connects ERPNext to KSeF so structured invoices are generated from the sales order and submitted through the national system, and the returned identifiers are stored against the invoice record.
No per-user licence fees
ERPNext is open source. A forty-person Mittelstand supplier pays for implementation and hosting, not for seats, and the next ten users cost nothing in software. Against quotes that scale per user per month, that difference often decides whether the project happens.
Your data stays where you decide
ERPNext can be self-hosted on your own servers or with an EU hosting provider of your choice, which keeps GDPR data-residency questions simple to answer. There is no vendor holding your production data hostage to a subscription.
Built for job shops, not just ledgers
Work orders, routings, operation-wise costing, quality checks and quoting from real bills of materials are the core of ERPNext, not add-ons. Estimators quote from what similar jobs actually cost, and margin per order is visible while the order is still running.
Documentation your customers audit
Whether you hold ISO 9001, IATF 16949 or EN 9100, customers audit records rather than intentions. ERPNext maintains lot and serial traceability, inspection results, nonconformance records and calibration schedules linked to every delivery.
Cost base that fits Polish manufacturing
Polish suppliers compete on precision and price, and an ERP that charges per user per month eats into exactly that advantage. Open-source licensing keeps the software cost fixed while the team grows.

How We Implement
How an ERPNext implementation runs in Poland
European manufacturers rarely have staff to spare for a two-year ERP programme. Sigzen's approach puts a working system into a small team's hands quickly and deepens it from there, with every session scheduled inside your working day.
- 1
Discovery in your hours
Sigzen maps how your plant actually runs: quoting, purchasing, the route a part takes through the shop, inspection points, dispatch and invoicing. India sits three and a half to four and a half hours ahead of Central European Time, so these sessions run in your morning and afternoon rather than at either side's inconvenience.
- 2
Set up the KSeF integration
The KSeF connection is configured and tested in the test environment before go-live, with structured invoice generation, submission and identifier storage running from the same record that holds the order.
- 3
Configure the shop floor
Bills of materials, routings, work orders, operation-wise job costing and quality checkpoints are configured to mirror the mapped flow, with scrap and rework captured exactly where material is actually lost.
- 4
Migrate data cleanly
Customers, suppliers, parts, bills of materials, open orders and balances move across from your existing system or spreadsheets after verification and de-duplication. Historical job costs come too, because that history is what makes future quoting accurate.
- 5
Test with your own orders
Recent real orders run end to end before go-live: enquiry, order, purchase, production, inspection, delivery note and invoice. Testing on your own parts exposes the gaps while they are still cheap to fix.
- 6
Train by role, recorded
Estimators, buyers, shop supervisors, quality and accounting each learn their daily screens on your own data. Sessions are recorded so the next hire trains from the same material.
- 7
Go live, then keep improving
Sigzen supports the first weeks live during your working day, including the first month-end close. After stabilisation the work turns to the reports owners actually run on: margin per order, on-time delivery, scrap by reason, quote-to-win rate.
Good to Know
Frequently asked questions
Does ERPNext work with KSeF?
Yes, with configuration. Sigzen connects ERPNext to KSeF so structured invoices are generated from the sales order, submitted through the national system and their returned identifiers stored against the invoice record. The connection is tested in the test environment before go-live. KSeF has applied to large taxpayers since February 2026 and to all B2B transactions since April 2026, with the smallest businesses following in January 2027.
Why do Polish manufacturers choose ERPNext over local ERP vendors?
Cost structure and depth together. ERPNext has no per-user licence fees and still covers quoting, work orders, routings, quality, traceability and accounting in one system, which protects the price advantage Polish suppliers compete on.
Can ERPNext meet aerospace and automotive audit requirements?
Yes. Revision control, lot and serial traceability, inspection and calibration records, nonconformance and corrective actions are maintained as work happens, configured to your existing EN 9100 or IATF 16949 quality system.
Where is our data stored?
Wherever you decide. ERPNext can be self-hosted on your own servers or with an EU hosting provider, which keeps GDPR data-residency questions straightforward.
How does a Polish company work with an ERPNext partner in India?
India runs three and a half to four and a half hours ahead of Central European Time, so Sigzen's team covers your full working day. Implementation is remote with on-site visits where a project needs them, and sessions are recorded.
Can ERPNext handle export sales to Germany and western Europe?
Yes. Multi-currency sales, export documentation and EU VAT treatment run alongside domestic PLN invoicing in one system.
