Compliance note

Financial promotions communicated on apps regulated under FSMA 2000 must be approved by an FCA-authorised person (Section 21)-this is a criminal liability issue, not an optional compliance step.

Buyer's Checklist

What to look for in a fintech & finance mobile app developer in Krakow

These are the questions and checks that separate fintech & finance specialists from general app agencies who will list your sector on their homepage after you sign.

Demonstrated understanding of FCA financial promotions rules-confirm the agency knows that CTA copy on regulated pages must be signed off by an FCA-authorised person

Secure form handling for sensitive financial data: TLS 1.3, explicit no-storage policy for application data submitted via web forms

Calculator and comparison tool architecture: hardcoded rate sliders are not compliant; rates must pull from a backend with an audit log

FSCS protection wording display: this must appear in the correct format on the homepage and relevant product pages-agencies that don't know this will need post-launch legal correction

Load speed for product pages: Google strongly favours fast-loading financial pages because slow financial sites lose to comparison platforms in organic rankings

Platforms & Tech Stack

Which platform for fintech & finance in Krakow?

Next.js (custom)

The dominant choice for FCA-regulated web products in Krakow-gives full control over data handling, metadata, and component architecture without the compliance risks of page-builder CMS platforms.

React + Headless CMS (Contentful/Sanity)

Suitable for content-heavy financial services sites where legal and compliance teams need to update product information without developer involvement-with version control and approval workflows.

WordPress (custom theme-not page builders)

Acceptable for financial advisory firms and accountants with lower compliance complexity. Must be custom-themed-Elementor and Divi introduce security and accessibility vulnerabilities incompatible with FCA-regulated contexts.

Embedded compliance tools

Konsentus, Comply Advantage, and Onfido provide AML/KYC and PEP screening embeds. These are separate from app development but the agency should know how to integrate them without breaking page performance.

Questions & Answers

Fintech & Finance mobile app development in Krakow - common questions

Pre-brief questions that fintech & finance businesses in Krakow ask before commissioning an app project.

Do financial apps in Krakow need FCA approval before going live?+

Financial promotions communicated by FCA-regulated firms (or on their behalf) must be approved by the firm's compliance function or an FCA-authorised third party under Section 21 FSMA. This applies to product descriptions, rate claims, and CTAs on apps. Unauthorised financial promotions carry criminal liability. Any Krakow app development agency working in financial services should flag this at the brief stage, not after launch.

Can I use WordPress for a fintech app?+

WordPress is acceptable for lower-complexity financial advisory and accounting apps. It is not recommended for FCA-regulated product pages, client portals, or any site handling financial application data-the security attack surface of public plugins and the data handling of page builders like Elementor are incompatible with FCA-regulated environments. Next.js custom builds are the defensible choice for regulated products in Krakow.

How much does a financial services app cost in Krakow?+

An accountancy or financial advisory app costs £3,000–£9,000. An FCA-regulated product landing site with compliant copy and secure form handling costs £8,000–£25,000. A fintech startup marketing site with product integrations is £12,000–£40,000. These figures exclude legal review of financial promotions copy, which is a separate cost typically £1,000–£3,000 per compliance review.

What should a Krakow business look for in a contract before hiring a web developer?+

A properly scoped mobile app development contract for a Krakow business should include: a fixed-price quote (not hourly with uncapped scope), a detailed scope of work document, a timeline with specific milestones and delivery dates, ownership of all source code and assets on completion, a warranty period of at least 30 days post-launch for bug fixing, and clear terms for revision rounds. Avoid any contract that includes a retainer obligation as a condition of handover — this is a red flag in the Krakow mobile app development market.

How long does a Krakow web project typically take from brief to launch?+

A standard business app for a Krakow company takes 2–4 weeks from brief to launch (assuming content is provided on time). A custom web application with integrations typically takes 6–12 weeks. E-commerce sites with product catalogue setup take 3–8 weeks. The most common cause of delays in Krakow web projects is late content delivery from the client — agree a content deadline before the project starts and the timeline holds reliably.

Should a Krakow business hire a local web developer or work with a remote agency?+

For most Krakow businesses, a remote mobile app development agency delivers equivalent or better results than a local studio — at 20–40% lower cost. The key factors are: quality of portfolio (verifiable through live URLs, not PDF screenshots), communication responsiveness (same-day replies are the baseline for professional agencies), and clear ownership transfer on handover. Physical location has not been a meaningful differentiator for mobile app development quality since 2018. Tkist serves clients across Poland and 40+ countries entirely remotely.

How can a Krakow business verify a web developer's experience before signing?+

The three most reliable verification methods for Krakow businesses evaluating mobile app developers are: 1) Live portfolio links — the agency should provide direct URLs to live sites they built (not PDF mockups), which you can test for speed, mobile quality, and design; 2) Client references — ask for contact details for two recent clients in a similar sector; 3) Technical audit — ask the developer to explain how they would handle a specific technical challenge for your project. A developer who cannot answer this clearly has not built what they claim. Tkist provides live portfolio URLs, verified client references, and a free technical scoping call for every Krakow project enquiry.
