Our web projects

What we build for clients

Products are the public part of our work. Most of what we have built over two decades is custom web software for companies: delivered as a working system, hosted, and maintained. This is what that usually looks like.

Niche SaaS tools

Subscription tools for narrow professional tasks where off-the-shelf software does not exist. FX Diff is ours and it is live: FIFO exchange-rate differences for Polish sole traders, at fxdiff.pl.

Online calculators and quoting tools

Price calculators built into your site that turn a visitor's specification into an order. We built online printing calculators with order placement for Printstore Group, and they run the front of the sales funnel.

Custom CRMs and internal tools

Order management and client tracking shaped around one company's workflow, instead of forcing the company into generic software. Printstore Group manages customer orders in a CRM we built for them.

B2B ordering portals

Portals where your clients place and track orders themselves. The Paperstore paper-ordering service we built for Printstore Group is exactly that: customers order, staff process, nobody retypes emails.

Escaping the spreadsheet

When Excel stops scaling: several people editing at once, formulas nobody dares to touch. We turn a working spreadsheet into a web system and keep the logic people already trust.

We do not bill by the hour. You approve a fixed scope and a fixed price, and you get a finished product on the agreed date. Once the spec is signed off, there are no surprises.
