1

Itransition

Large global IT services group with a Warsaw entity, working in ERP, CRM, Microsoft Dynamics, Salesforce and data.

Clutch: 4.9 (42 reviews)Rate: 25–49 USD/hMin. project: 25,000 USDPremier Verified

Best for: Mid-size and large companies rolling out Microsoft Dynamics, Salesforce or an ERP that want a global vendor with a Polish invoice.

Pros

• Itransition has been a Microsoft partner since 2008. The site also lists Odoo Silver, Salesforce and AWS partnerships.
• The job boards showed 27 open roles, 24 of them remote.

Cons

• The Polish company belongs to Itransition Holdco Limited, and Clutch puts the group headquarters in Decatur, GA.
• The declared rate of 25 to 49 USD is the offshore band, so ask where your team will sit.
• GoWork shows few employee reviews, all negative (0 positive, 4 negative), and 2 of them mention layoffs.

From their website and Clutch profile

• The homepage claims 3,000+ engineers, 800+ clients and over 25 years in business. The Polish company in KRS dates from 2017 (source).

Verdict. Pick Itransition for Dynamics, Salesforce or ERP rollouts at company scale. For a small custom product, the 25,000 USD minimum and the global delivery model are a poor fit.

2

Verdict. Use Andersen to scale a team you lead, backed by 129 Clutch reviews. Check who signs the contract, given the thin Polish margin and the multi-entity setup.

Web development and WordPressMobile appsAI development and chatbotsCustom softwareWebsite maintenance (SLA)Search experience optimizationAI

Verdict. Develtio fits websites and small apps, where its client reviews matter more than scale. The filings do not support the team size on the site, so ask who will do the work.

All companies in the data set, with the same score. Companies without a confirmed office, sole traders, body-leasing firms and product companies are listed but not ranked.

Who is not in the top 10, and why

What they charge

Check any agency yourself in 10 minutes

1. React Native lets a web team ship mobile apps, which is its strength and its trap. Ask for apps in the stores you can install today and how they handle the new architecture.
2. Find the legal entity in the National Court Register: the seat, the share capital and the shareholders. An office here with a seat in another city is a sales office, not a team.
3. Read the last financial statement on rejestr.io: revenue, profit or loss, and whether it was filed on time.
4. Check the VAT white list: active, and the name matches the contract.
5. On the Clutch list hover over the company link; a link through ppc.clutch.co is an ad. Then read the reviews themselves.
6. On GoWork read the employee reviews, not the stars, and look for layoffs and rotation.
7. Ask who exactly will work on your project, and check those people on LinkedIn.
