Comarch XL, Enova365, Subiekt GT: which ERP for a B2B company

Three ERP systems dominate conversations with Polish B2B companies planning to integrate with an e-commerce platform: Subiekt GT, Enova365 and Comarch XL. Each has different strengths, different implementation costs and different demands on the store platform. The choice is not a technical matter; it is a decision about how the company wants to run its operations for the next several years.

We write this from the integration perspective, because that is where our work sits: a well-matched ERP means less effort connecting it to the store, fewer architectural compromises and fewer problems during deployment. A poorly matched ERP means a project that costs twice as much as planned.

Subiekt GT: proven choice for retail and straightforward B2B sales

Subiekt GT is an Insert product that has been present in Polish small and medium trade companies for years. Its main advantages are low licence cost, Polish documentation and support, fast deployment and an interface that non-technical staff can use without much training.

In the e-commerce context Subiekt GT works well alongside the Sello module (also from Insert), which handles multichannel sales, Allegro integration and a basic connection to an online store. For companies selling finished products with a relatively simple pricing model that is often enough.

Where Subiekt GT reaches its limits: complex B2B pricing structures (per-customer pricelists, tiered discounts, framework agreements), multi-warehouse management, project-based billing, advanced production management. As the company grows and processes become more complex, Subiekt GT requires workarounds or customisation that over time cost more than migrating to a different system.

For whom: trading companies with one or a few warehouses, straightforward B2B sales without complex commercial terms, implementation budgets below a few tens of thousands of PLN.

Enova365: modular flexibility for growing companies

Enova365 (Soneta) won its mid-market popularity through a modular pricing model. You buy and pay only for the modules you actually use: trade, warehousing, accounting, HR and payroll, CRM. It is available as SaaS (subscription) or as a perpetual licence with on-premise installation, giving flexibility depending on the company’s IT policy.

From the e-commerce integration perspective Enova365 has well-documented API and proven integration patterns. Synchronising stock levels, prices, contractors and orders is achievable without custom-built solutions. We see this system in projects where the client plans from the outset for the B2B store to be a frontend layer on top of ERP-managed processes.

The strong HR and payroll module means Enova365 is sometimes chosen for reasons unrelated to e-commerce, with the store integration coming as a later step. That works because the system is designed with openness in mind.

Where Enova365 reaches its limits: highly complex manufacturing processes, multi-entity group accounting, requirements at large-corporate scale. With a few dozen users and standard trade processes Enova365 handles everything comfortably. With several hundred users and non-standard processes a ceiling becomes visible.

For whom: growing companies with 10 to 150 employees, a need for a reliable API for e-commerce integration, a preference for rolling out modules incrementally without paying for unused features.

Comarch XL: a system for complex corporate operations

Comarch XL is built for companies with complex manufacturing processes, extensive logistics, multiple warehouses and legal entities, or those selling in industries where batch tracking and documentation are required (manufacturing, FMCG, pharmaceuticals).

The configuration options are broad, which translates to a long implementation timeline and a high project cost. Integrating Comarch XL with an e-commerce platform is technically feasible but requires experience: the system has its own data exchange standards (XL API) that differ from typical REST APIs. We have seen projects where underestimating the ERP-side integration work doubled the store implementation budget.

On the other hand, companies that have been running on Comarch XL for years rarely want to move away from it because the system is deeply embedded in their processes. In that case the question is not “which ERP to choose” but “how to integrate it well with the platform,” and team experience makes the difference there.

For whom: manufacturing or trading companies with corporate-level processes, holding groups, industries with strict regulatory requirements (batch tracking, certificates), companies already running Comarch XL that need e-commerce integration.

How to choose an ERP for a B2B company

Comparing ERP systems only makes sense when you are asking about specific processes, not generic features. A few questions we ask at the start of every conversation:

How many warehouses do you have, and does one system manage them all? The more locations, the more important multi-warehouse ERP capabilities become. Subiekt GT handles this less robustly than Enova365 or Comarch XL.

Do you have individual commercial terms per contractor? Per-customer pricelists, discount groups, framework agreements. The more complex these are, the more important it becomes that the ERP exports them to the B2B store in a clean, usable format.

Are you planning document automation? Invoices, corrections and warehouse documents generated automatically from the store are standard in mature B2B setups. Different ERP systems have very different levels of readiness for this.

What is your growth horizon? A system deployed for three years has different requirements than one expected to run for a decade. Migrating between ERP systems mid-growth is expensive and risky.

ERP and store integration: where the actual work is

Choosing an ERP is a starting point. The real challenge is a well-designed integration that synchronises data in both directions without duplicating errors, delays or losing consistency. We cover this in the article on integrating B2B platforms with ERP and PIM systems.

If you are also selecting a PIM system for product catalogue management, read our comparison of Pimcore, Ergonode and Akeneo, because PIM and ERP choices should be architecturally consistent.

We work on both greenfield ERP deployments with store integration, and on projects where the ERP is already in place and needs to be connected to a new or migrated store. Details on the ERP and PIM implementation service page and on the integrations and platform automation page.
