Bespoke line-of-business software, built around how you actually work
We design and build bespoke B2B applications — internal tools, portals, integrations, and workflow systems — engineered to match how your business runs rather than forcing it into off-the-shelf constraints.
Most companies reach a point where the spreadsheets, disconnected tools, and manual handoffs stop scaling. The work that keeps the business running lives in people's heads and in files no one else can see. A custom application turns that into a system your whole team can rely on — built for your process, your data, and your users.
Mariyano takes these engagements end to end: discovery, design, build, integration, and ongoing support. We connect to the systems you already run, model the workflows that matter, and deliver software that fits cleanly into daily operations rather than adding another silo. We favour clear, maintainable code over clever shortcuts, so the result is something your team can grow with.
As the company behind Zipflow, YokoCart, UltraBI, and Fezo, we bring product-grade engineering to client work. Where one of our platforms is the right foundation we will say so; where bespoke is the right call, we build it properly, with no lock-in to tooling only we can maintain.
Move critical operations out of fragile spreadsheets and email threads into a single system with proper validation, access control, and an audit trail.
Tie together the tools you already run so data moves automatically between them, eliminating duplicate entry and the errors that come with it.
Give external parties a secure place to transact with you — requests, approvals, documents, and status — without overloading your team with manual back-and-forth.
When your workflow is specific enough that off-the-shelf tools force compromises, we build software shaped around how your business actually operates.
