We are Codelines

We build and run the systems our clients' daily operations depend on: warehouse, sales, billing. We stay with them when things get hard.

Who we are

About us

We're a software house based in Poland. We build software for companies where the system isn't an add-on but the foundation: warehouse, transport, sales, billing. When that system goes down, the whole business stops. We treat it that way.

We don't disappear after launch. We've been with Rulewave since 2010, and have run its current warehouse system since 2019. Hundreds of thousands of operations a year, no critical outage, no data loss. We've been developing Tesoro and TransHans since 2022. You get one partner for the long run, not a carousel of freelancers you onboard from scratch every time. For anyone choosing a nearshore partner, that's the whole point: our turnover is low, so the engineers who learn your system are the ones still supporting it years later.

We're not the cheapest option, and we're not a website factory. We don't sell a "modern stack" or "a passionate young team". Everyone says that, and it proves nothing. We start with your process, not a list of technologies, and we tell you plainly what can be done and what can't.

How we work

Code is a tool

Code is the means, not the point. What matters is whether the system works, supports the operation and stays maintainable for years. So:

  • Process first, code second

    Before we write a line, we understand how your operation runs. We build for the process, not for a fashionable framework.

  • We own what we build

    We maintain the systems we ship. When SAP changes its API or a new carrier comes in, we pick up the phone. Five years on, too.

  • We take on the hard integrations

    Real-time SAP, e-invoicing, GPS tracking, payments. Where others turn back, we've already shipped it to production.

Get in touch

Let's talk about your system

Got a process running on spreadsheets, or a system no one supports anymore? Tell us what you actually want to fix, and we'll tell you how we'd approach it.

  • Real systems, not prototypes

    WMS, CRM, SAP / e-invoicing / GPS integrations, live in production.

  • A partner for the long run

    we've run Rulewave since 2010; Tesoro and TransHans since 2022. No key client has left.

  • You talk to an engineer, not a salesperson

    we say plainly what we'll do and what it means for your business.
