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.
