Integrations
Each external system (ERP, CRM, courier, payment) adds mapping, error handling and testing on real data. Systems without an API cost more.

Pricing / Estimates
How much does custom software cost? Indicative ranges by project type
Exact prices depend on scope, but you should not have to book a call to learn the order of magnitude. Below are typical ranges for the projects we do most often, in PLN net, and what moves the price up or down.
- Discovery
- API
- MVP
- B2B + ERP
- Modernisation
- Support
Ranges
Indicative ranges by project type
| Project | Typical range | Time | What it usually includes |
|---|---|---|---|
| Discovery and system audit | 5–15k PLN | 1–3 weeks | Process and data map, review of current systems, scope, estimate and risk list. |
| API integration (one flow) | 15–50k PLN | 3–8 weeks | For example orders from the shop to the ERP, with logs, retries and an error panel. |
| Web application MVP | 40–120k PLN | 2–4 months | One core process, roles, admin panel, first integrations and deployment. |
| B2B platform with ERP integration | 75–250k+ PLN | 3–6 months | Customer accounts, price lists, orders, documents and two-way ERP sync. |
| PHP / Laravel modernisation | from 8k PLN audit, then stages of 20–60k | per stage 1–2 months | Audit, tests, upgrades and replacing modules step by step without stopping the system. |
| Maintenance and development | monthly package by hours | ongoing | Monitoring, updates, fixes and small changes with agreed response times. |
PLN net. Ranges for typical scope; the final estimate follows a short discovery. EUR ≈ PLN / 4.3.
Cost drivers
What drives the price
Roles and business rules
Customer-specific prices, approvals and permissions are usually the bulk of a B2B system, more than the screens.
Data migration
Moving data from spreadsheets or an old system takes cleaning and verification – often underestimated.
Security and compliance
SSO, audit logs, NIS2 documentation or on-premise deployment add work, but are cheaper planned up front than added later.
Languages and design
Each language version and a custom design system add work; a clean, consistent UI based on components costs less.
Deadline
A fixed date with fixed scope needs a bigger team. Flexible scope keeps cost down.
Delivery model
How we get to a fixed price
30-minute call
You get the order of magnitude straight away.
Discovery
1–3 weeks; ends with scope, estimate and risk list.
Price per stage
Fixed price for each stage, paid per milestone.
Further stages
Next stages are priced after you see the first one working.
FAQ
Questions before starting
Why do you not give one fixed price on the website?
Because two systems called “B2B platform” can differ several times in scope. Ranges show the order of magnitude; the fixed price per stage comes after discovery.
Do you work fixed price or time and materials?
Both. Defined stages usually go as fixed price; ongoing development and support as a monthly package of hours.
Is a ready-made system cheaper?
At the start usually yes. Custom software pays off when the process is a competitive advantage or needs integrations a product does not support.
How much does maintenance cost?
It depends on the size of the system and response times. Most clients use a monthly package of hours with monitoring and updates included.
