Custom software development
Web applications, internal tools, and customer-facing products, built on a stack chosen for your team's constraints rather than ours.
Kraków, Poland
Software and financial process work, built to hold up under real use.
ESQUERCUS Sp. z o.o. designs and maintains business software, and advises on the financial and reporting processes that run behind it. One team, two disciplines, working from Kraków for clients who need both to work together.

About the company
A small firm built around a specific overlap.
ESQUERCUS Sp. z o.o. is registered in Kraków under PKD codes covering software development (62.01.Z) and other financial service activities not elsewhere classified, excluding insurance and pension funding (64.99.Z). In practice, that means we take on the kind of work that usually gets split between two vendors: the system that runs a business process, and the financial logic that process depends on.
We keep engagements small enough to stay hands-on. That usually means a compact team assigned to your project from kickoff to handover, direct access to the people doing the work, and documentation you can actually hand to your own staff afterwards.

Services
Where we spend our time
Five areas cover most of what clients bring to us — from a first prototype to the reporting process that has to run every quarter after it ships.
Systems & integration
Connecting the software you already run — accounting platforms, CRMs, internal databases — so data moves between them without manual re-entry.
Financial & process advisory
Reviewing how figures move through a business — from source records to management reports — and tightening the steps that introduce risk or delay.
Data & reporting
Dashboards and recurring reports built from your own data, so the numbers a founder or a board sees are pulled, not assembled by hand each month.
Support & maintenance
Ongoing fixes, small feature work, and monitoring once a system is live, under a retainer sized to how much change your product actually sees.
Security & access review
A practical pass over authentication, permissions, and data handling in existing systems, with a short list of fixes ranked by actual exposure.
Why clients stay with us
What working with us is actually like
-
You talk to the person doing the work
No account layer between you and the engineer or analyst on your project — questions get answered by someone who knows the answer.
-
Scope is written down before work starts
Every engagement begins with a short written brief covering deliverables, timeline, and cost, agreed before any billing begins.
-
Software and finance logic reviewed together
Because both disciplines sit under one roof, a reporting requirement doesn't get lost in translation between "the dev team" and "the finance team."
-
Handover includes documentation
At the end of a project you receive plain-language notes on how the system works, not just the code and a shrug.
