Codelines

Codelines is a nearshore software house in Poland. We build and run the systems our clients' daily operations depend on: warehouse, transport, sales and billing. We also take on the integrations others avoid, like real-time SAP, e-invoicing (KSeF), payments, GPS tracking and AI.

What we do:

• Custom software built around your process
• Web application and SaaS development, from concept to production

System integration: ERP/SAP, payments (Stripe), messaging (Twilio, WhatsApp), carriers (DHL)

• Logistics software: WMS, deliveries, real-time tracking
• Web portals and dashboards
• Staff augmentation

Why clients stay:

Long-term ownership. We have run a global logistics provider's warehouse management system since 2010. It handles hundreds of thousands of shipments, documents and transactions a year, with no critical outage and no data loss. We have been developing Tesoro (real-estate SaaS) and TransHans (transport) since 2022. No key client has left.

Low team turnover. The engineers who build your system are the ones still supporting it years later. That is the point of nearshoring done right.

You talk to an engineer, not a sales rep. We start with your process, not a tech stack, and tell you plainly what can be done and what can't.

We are not the cheapest option and not a website factory. If your business runs on a system that has to keep working, let's talk about your process.
