Custom web applications and SaaS products

We build web applications that replace spreadsheets, connect systems and serve customers: from an internal panel for your team to a subscription product. We know what it looks like from the other side, because we develop and maintain our own SaaS products.

Sound familiar?

When does a company need its own web application?

The company runs on spreadsheets that only one person understands, and dreads that person's vacation.

You type the same data by hand into three systems that don't talk to each other.

Off-the-shelf software does 80% of what you need, and you work around the rest manually.

You have an idea for a SaaS product but no team to build and maintain it.

An app written years ago slows down with every new customer and nobody wants to touch it.

The data is sensitive and cannot go to an external cloud.

What we build

The web applications we create

A few examples from projects we run.

Internal panels and systems

A production panel for a print shop with PDF generation, printer support and shipping via InPost and DPD. A helpdesk that has handled over 63,000 tickets.

Parking with Dahua cameras

Cameras read licence plates, and the system checks the reservation and the whitelist before opening the barrier. Staff see a photo of every entry and the system's decision in the panel. Cameras from other manufacturers and external systems connect through adapters and an API.

New products from a phone to Subiekt and the shop

An employee at the goods scans the EAN code and takes photos. The app pulls data from Subiekt, removes the background and prepares an AI-written description, and the product goes to the shop and back to Subiekt. It works on a phone like an app (PWA).

SaaS products

Subscription apps with customer accounts, billing and multiple companies on one instance. Our own products are built this way.

Integrations and automation

We connect the app to e-commerce, Allegro (Poland's largest marketplace), BaseLinker, ERP and CRM. Automatic matching of bank transfers to orders freed up one full-time position at B2Wed.

AI in the app

Document search, text recognition from scans, chats based on company knowledge. Locally run models for sensitive data.

AI automation →

Monitoring and market data

Tools that track competitor prices and marketplace listings, then suggest price changes or make them automatically.

Taking over and developing an existing app

Code review, tests where they are missing, dependency updates and a plan for developing the app without rewriting everything from scratch.

Our products

We build and maintain SaaS ourselves

That is how we know what matters in an app after a year of use, not just on launch day.

ASAPChat

AI chat for online shops. Handles a website widget, Messenger, WhatsApp, Instagram, Allegro and email. Laravel, Octane, Typesense, Redis.

asapchat.io →

asapbase

Orders from multiple shops and marketplaces in one panel. A multi-tenant Laravel app with live data refresh.

asapbase.com →

SamorzadAI

An AI assistant for local government offices: it answers residents, digitises documents and helps officials.

How we work

How a web application gets built

Workshop and scope

We discuss the process the app is meant to handle and the people who will use it. We agree what must be in the first version.

Proposal

Within 1–2 business days you get the scope, stack, schedule and quote.

Iterative build

Every few weeks we deliver a working part of the app. Every change goes through code review.

Deployment

We launch the app on your server or ours, with backups and monitoring.

Growth

We keep developing the app, or hand it over to your team along with documentation.

Case studies

Applications that changed how our clients work

SaaS · AI

−40%

ASAPChat

AI chat for e-commerce. Customer service costs lower by up to 40%, Allegro disputes resolved 70% faster.

Automation

1 FTE

B2Wed

Bank transfers matched to orders automatically, with the help of AI. The manual work is gone.

Warehouse

+40%

Faster order picking

A label and picking app: a product list with warehouse locations, and a scan changes the order status.

Cost

How much does a web application cost?

The price depends mainly on: the number of features and user roles, integrations with other systems, security and data storage requirements, and whether we design the interface from scratch.

Not sure yet what exactly you need? Start with an MVP, meaning a first version with what matters most. After a conversation, we send a proposal with the scope, stack and quote within 1–2 business days.

Alongside your systems

A web application alongside your ERP and other systems

We do not replace what works for you. We build an application that adds the missing function next to your current systems and does not disrupt day-to-day work.

We connect, we do not replace

The application plugs into your e-commerce, Allegro, BaseLinker, ERP and CRM. The data stays where it is, and we remove the manual re-entry between systems.

Fitting your rules

We keep to your technology, security policies and way of deploying. The application can run on the client's server, on-premise or in the cloud.

The missing function, not a revolution

An off-the-shelf system does 80% of the work you need. We build the other 20%, so the team does not have to work around it by hand or change a core that works well.

Support for your IT team

We work with your team, not instead of it. You get the code, the repository and the documentation, so your own IT can keep developing and maintaining the application.

FAQ

Questions about web applications

How much does a custom web application cost?

It depends on the number of features and user roles, integrations with other systems and data requirements. After a conversation, we send a proposal with the scope, stack and quote within 1–2 business days.

What technologies do you use to build web applications?

Most often Laravel on the server side and React and Next.js on the interface side. We choose the technology to fit the problem: a panel for five people is built differently from a SaaS for hundreds of companies.

Can the application run on our server?

Yes. We deploy applications in the cloud, on our servers or on-premise at the client. For sensitive data, such as medical data, everything including AI models can run locally.

Will we own the code?

Yes. You get the code, repository access and documentation. You can keep developing the app with us or with your own team.

Will you take over an application written by someone else?

Yes. We start with a review of the code and infrastructure, then propose a plan: what to fix right away, what to rewrite and what to leave.

Where do I start if I'm not sure about my idea?

With an MVP, meaning a first version with a minimal set of features that you can show to users. We usually build it in about 6 weeks.

Do we have to replace our current systems to get a web application?

No. We adapt to what already works for you and add a layer on top: an application that connects to your ERP, CRM, shop or Allegro and takes over what you now do by hand. We do not touch a core that works well.
