Custom CRM and ERP Systems

We design and build systems tailored to your processes — CRM, ERP, B2B portals, and workflow tools. Instead of adapting your company to off-the-shelf software, we adapt the software to how your company actually works.

What kinds of systems do we build?

Every company works differently — that's why we don't sell off-the-shelf packages. Below are the most common types of systems we design and deliver for B2B clients.

Start a Project

CRM Systems

Customer relationship management tools built around your sales process — not the other way around. Contact history, sales pipeline, quotes, reminders, and reporting in one place.

ERP and ERP-class Systems

Company resource management: orders, inventory, production, documents, finance. We build both complete systems and modules that complement your existing environment.

B2B Panels and Portals

Dedicated platforms for your business partners: placing orders, individual price lists, credit limits, transaction history and documents — available to clients 24/7 without involving a sales rep.

Workflow and Document Management Systems

Automation of internal processes: requests, multi-level approvals, document flow, notifications, and a full change history.

Internal Panels and Operational Tools

Systems supporting a specific department or process — project management, scheduling, settlements, operational reporting.

Industry-specific Systems

Solutions tailored to industry specifics that no off-the-shelf software covers — from logistics and manufacturing to professional services.

What does your company gain?

Processes, not workarounds

The system mirrors how you actually work — no more side spreadsheets, manual data re-entry, or working around a tool's limitations.

One source of truth

No more data scattered across Excel, your inbox, and three different systems. Everything in one place, up to date, and accessible to the right people.

Automation of repetitive work

Notifications, document generation, approvals, recurring reports — tasks that take hours today now happen on their own.

Scalability without rising fees

Adding a user or a module doesn't mean another subscription. The system grows with your company, on your terms.

Control over data and security

Your data stays in infrastructure of your choosing, with permissions matched to your organization's structure and production-grade security standards.

Real reporting

Metrics calculated the way your management actually needs them — not the way an off-the-shelf software vendor decided.

Custom system or off-the-shelf software?

It's worth asking this question before you start looking for a contractor. Not every company needs a system built from scratch — and we say that outright.

Off-the-shelf software

Quick start, standard processes, a stable number of users.

  • Fit to your processes

    You adapt the way you work to what the system offers

  • Time to first result

    Fast — within the ready-made features

  • Users

    Works well for a small, stable number of people

  • Integrations

    Only where the vendor has a ready-made connector

  • Feature scope

    You pay for a package — including what you don't use

  • Cost over time

    The subscription grows with users and features

  • Development

    Changes depend on the vendor's roadmap

Custom system

We build exactly what you need — no unnecessary modules, full control.

  • Fit to your processes

    The system mirrors the processes that give you an edge

  • Time to first result

    First working version in weeks, not a year

  • Users

    Grows with your company, no license limits

  • Integrations

    Even with legacy systems and where there's no ready API

  • Feature scope

    We build what you need; no unnecessary modules

  • Cost over time

    An investment in your own system, no rising license fees

  • Development

    Your company sets the priorities

Choose off-the-shelf if…

Your processes are standard and don't require deep customization.

  • Your processes are standard and fit what's available on the market
  • You need a working solution in a short time
  • The number of users is small and stable
  • You have no specific integration requirements

Choose a custom system if…

Your edge comes from a process that can't be replicated in a standard tool.

  • Off-the-shelf systems force you to work around their limitations instead of supporting how you work
  • You pay for features you don't use, and the key ones are missing
  • You need integrations with systems that have no ready-made connectors
  • Your competitive edge comes from a process that can't be replicated in a standard tool
  • Subscription costs are growing faster than your company

Integrations — a system that talks to the rest of your environment

A custom system only makes sense if it works together with the tools you already use. We build two-way integrations — data flows both ways, without manual exports.

ERP systems

Comarch, SAP, enova, Symfonia, as well as custom-built solutions and legacy systems without a modern API

E-commerce

PrestaShop, WooCommerce, Shopify, headless storefronts

Multichannel sales platforms

Base (formerly BaseLinker), marketplaces

Accounting and invoicing systems

Automated sales document workflows

Communication tools

Email, calendars, internal company messengers

Warehouse and logistics

Stock levels, courier integrations, WMS

Payments

Payment gateways, deferred payments, B2B credit limits

External APIs

Business registries, VAT validation, exchange rates, any service with API documentation

Why we build systems in modern technology

Most CRM and ERP systems still running today were built on decade-old technology.
They work, but using them feels like working in 2010 software.

An interface employees don't avoid

We build systems in Next.js and React — the same technologies modern SaaS applications are made of. The result: the interface responds instantly, and the team actually uses it instead of going back to Excel.

Lower maintenance cost

PostgreSQL and open-source technologies instead of costly licenses and a narrow pool of specialists in outdated solutions. Any competent team can maintain your system.

Faster iterations, earlier results

A modern stack lets us work incrementally. You see the first working version of the system in weeks, not a year — and you can actually influence it.

Ready for what comes next

An API-based architecture means the system is prepared for extensions: a mobile app for your sales reps, a portal for your business partners, integrations with AI tools.

A flexible approach

We're not dogmatic about technology. Next.js and PostgreSQL are our default choice because they work best in most projects. If your environment calls for a different approach, we'll match the stack to the project, not the other way around.

What does working together on building a system look like?

01

Process and requirements analysis

We start by understanding how your company actually operates — who does what, and in what order. At this stage, it often turns out some processes are worth simplifying before we build them into the system.

02

Functional design and architecture

We map out the modules, data model, and integration plan. We decide what goes into the first version and what comes in later stages — so you see real value sooner.

03

Interface design (UX/UI)

We design screens and user flows. An internal system has to be comfortable to use — that's what determines whether your team will actually use it.

04

Development and integrations

We build the system incrementally, with regular demos. In parallel, we implement integrations with your existing environment.

05

Deployment, training, and ongoing development

We launch the system into production, train your team, and hand over documentation. After launch, we provide SLA support and keep developing the system as your company's needs evolve.

Do agencji PAGEART trafiłam po 2 nieudanych projektach strony mojej Kliniki Medycyny Estetycznej. Zaproponowano mi od samego początku świetną wizualizację, która w 100% spełniła moje oczekiwania. Kontakt z agencją PAGEART był bardzo dobry i wszystko należycie mi wyjaśniono.


Serdeczne podziękowania kieruje dla Pana Sebastiana, Pana Kamila oraz dla reszty zespołu 🙂

Miałem przyjemność współpracować przy realizacji dwóch projektów. Cały proces przebiegał sprawnie, zadania zostały wykonane szybko i zgodnie z ustaleniami. Bardzo dobry kontakt, elastyczne podejście i realne wsparcie na każdym etapie. Na pewno skorzystam ponownie.

Cieszę się, że trafiłem na PAGEART. Zespół zrealizował projekt kompleksowo: od koncepcji i projektu wizualnego po techniczne wdrożenie gotowej strony. Przez cały proces reagowali na potrzeby, wychodzili z inicjatywą i proponowali konkretne rozwiązania dopasowane do oczekiwań. Byli nastawieni na rozwiązywanie problemów, a nie ich tworzenie. Końcowy rezultat dobrze oddaje założenia, które wspólnie wypracowaliśmy. Pozdrawiam serdecznie całą ekipę.

Pageart to już trzecia agencja, która z nami współpracuję. Jeśli ten wysoki poziom się będzie utrzymywał – to na pewno ostatnia 🙂 Jako firma jesteśmy bardzo wymagającym klientem, ale to pokazuję, że po drugiej stronie mamy ambitnego kontrahenta, który nie boi się wyzwań, dlatego liczę, że to partnerstwo na lata. Pageart, od roku dba o naszą stronę internetową (fenbro.com), wdraża nowe usprawnienia i zapewnia stabilność działania (obecnie zajmują się stroną w wersji EN i DE) ….

Serdecznie polecam! Współpracowałam z agencją PageArt przy tworzeniu sklepu internetowego, którego projekt i realizacja przekroczyła moje oczekiwania. Sama współpraca przebiegła bardzo dobrze – dobry kontakt zarówno z Panem Sebastianiem jak i Projekt Managerem. Dziękuję za wykonaną pracę i polecam!

Polecam firmę Pageart. Wiedza specjalistów jak i jakość wykonania sklepu internetowego, stoi na najwyższym poziomie. Czułem się zaopiekowany na każdym etapie współpracy. Nie należę do najlżejszych klientów, ale agencja Pageart zrobiła na mnie wrażenie.

Świetni specjaliści! Miałam okazję współpracować z nimi z ramienia dwóch firm i w zupełnie różnych tematycznie branżach. W każdej ze stron świetnie poprowadziliśmy wszystkie kwestie developerskie, audytorskie i serwisowe. Polecam i mam nadzieję, że będę miała jeszcze okazję nie raz z nimi współpracować.

Bardzo profesjonalna agencja, która pomogła mi ruszyć w końcu ze sklepem internetowym. Miły kontakt, fachowe doradztwo, które było mi jako laikowi bardzo potrzebne. Do tego terminowa realizacja zleconych prac. Dziękuję i polecam!

Opinia Google


Zlecenie polegało na unowocześnieniu szaty graficznej firmy, chłopaki jednak od nowa napisali całą stronę dzieki czemu stała się wreszcie zauważalna w internecie i dotarła do szerszego grona konsumentów. Szybkość wykonania usługi na najwyższym poziomie.

Profesjonalna kadra która poważnie podchodzi do powierzonych im zadań. Polecam firmę do współpracy.

Frequently asked questions

Didn't find the answer?

Ask us anything
Cost depends mainly on the number of modules, process complexity, and integration scope. Narrow-scope systems handling a single process are significantly cheaper than a complete ERP environment. An accurate quote requires a conversation about scope — you can book a free consultation through the quick quote form.
The first working version covering a key process is usually ready within a few to several weeks. A complete ERP-class system with multiple modules and integrations is a project measured in months. It's worth noting that modern AI tooling can significantly speed up this process today. We work in stages, so you can use the first features before the whole system is complete.
No, and we usually advise against it. It makes more sense to start with the single most painful process, deploy it to production, and then grow the system with further modules. This way you see results sooner and can adjust direction along the way.
Yes — it's one of the most common elements of these projects. We integrate with systems such as Comarch, SAP, Enova, or Symfonia, as well as with custom-built solutions. If a system doesn't expose a modern API, we build a middleware layer that translates the data.
You do. We hand over the full source code along with documentation. We don't lock clients into working with us — if you decide to switch to another team in the future, they'll be able to take over development of the system.
Off-the-shelf systems offer a broad, generic set of features that your company has to adapt its processes to — and they're billed as a per-user subscription. A custom system mirrors how you actually work, doesn't include features you don't need, and its cost doesn't grow with your headcount.
Most often Next.js and React on the frontend, and Node.js and PostgreSQL on the backend and database side. We match the stack to the project — if the specifics of a client's environment call for a different approach, we propose the right solution.
We design systems to be understandable without a manual, but at launch we run a team training session and hand over documentation. For larger implementations, we also provide support during the first weeks of use.
We offer SLA-based support — ongoing technical care, security updates, monitoring, and development of new features. Most clients continue working with us after the main implementation is complete.
Yes. In that case we start with an audit of the existing code and architecture, to assess what's worth keeping and what needs rebuilding. Based on that, we put together a plan of action along with a quote.
