WislaCode Solutions

BACKGROUND

I am the CEO of GlobalTips

GlobalTips helps hospitality businesses accept payments, collect cashless tips, gather reviews and build guest loyalty through one platform.

OPPORTUNITY / CHALLENGE

• Increase repeat usage and guest spend in the GlobalTips iOS app by introducing a full loyalty programme: points, membership tiers with discounts, and a rewards catalogue from partner restaurants.
• Raise payment conversion across European markets by adding local payment methods to the app: BLIK and eBLIK in Poland, MB WAY in Portugal, and open-banking Pay by Account.
• Modernise the product across iOS and web: a shared design system, rebuilt digital menu, in-app analytics with A/B testing, and a scalable localisation pipeline for the whole ecosystem.
• Give waitstaff full self-service control over their earnings: real-time balances, tip pool distribution, a savings account, bank payouts, and a personal statistics dashboard.

SOLUTION

• Online Search
• Referral

• Good value for cost
• Referred to me
• Company values aligned

We have been working with WislaCode since July 2025. Our cooperation started with a single project related to the loyalty program in the GlobalTips guest app and gradually expanded into WislaCode taking responsibility for a significant part of our frontend development across the guest app, staff app, and web products. 

During this period, the team delivered a wide range of product improvements, including our loyalty program, restaurant messaging and push notifications, local payment methods such as BLIK, MB WAY and Pay by Account, digital menu search and navigation, migration to our new design system, analytics and A/B testing, localization infrastructure, and a redesigned onboarding flow for restaurant staff.

Some of these improvements have had a measurable impact on the product. In Poland, BLIK now accounts for almost 15% of payments made through our platform, and in Lithuania Pay by Account has reached a similar share. The loyalty program has helped increase guest return rates to participating restaurants, while the redesigned staff onboarding flow improved onboarding efficiency by approximately 30%.

They have also worked extensively on our web products, including restaurant and digital menu interfaces, payment page improvements, and our business, sales, admin, and staff panels.

One of the strongest aspects of our cooperation is delivery reliability. We work in monthly development cycles, and over 14 consecutive months WislaCode consistently delivered a new release, including regression testing and production-ready builds. For a fast-moving product company, this predictability is extremely valuable.

Another thing we appreciate is that the team does not simply implement specifications. They understand the product and regularly suggest technical improvements themselves. For example, they proposed improvements to our localization architecture and networking layer that made further development easier and faster.

Over time, WislaCode has moved from being an external development supplier to working much more like an integrated part of our product team. They are responsive, pragmatic, and able to work with changing priorities without losing the delivery rhythm.

If I had to name an area for further development, I would encourage the team to continue becoming even more proactive on the product side: challenging requirements and suggesting UX or product improvements in the same way they already proactively suggest technical improvements.

Overall, we are very satisfied with the cooperation and would recommend WislaCode to companies looking for a reliable long-term development partner rather than just additional engineering capacity.

RESULTS & FEEDBACK

The engagement grew from a single iOS feature to the entire frontend of the ecosystem: the guest app, the staff app and web, all delivered by the same team.

Thirteen consecutive monthly delivery cycles completed since January 2025, each closing with a production release to the App Store. The fourteenth is running now. No cycle was skipped.

All deadlines were met.

2-5 Employees

Describe the scope of work in detail. Please include a summary of key deliverables.

We needed an Android middleware between our POS partner HioPosCloud and payabl. POS terminals, and we needed it fast: merchant onboarding was blocked until the integration existed. WislaCode delivered it in one month, covering the full transaction lifecycle including refunds, reversals, batch closing and tips.

RESULTS & FEEDBACK

What were the measurable outcomes from the project that demonstrate progress or success?

Middleware delivered in 1 month, which unblocked merchant onboarding. First release covered the full transaction lifecycle: payments, refunds, reversals, batch closing and tips, plus retry and fallback handling for the unstable network conditions where POS integrations usually break.

Describe their project management. Did they deliver items on time? How did they respond to your needs?

The team consistently met deadline, communication was excellent and feedback loops very fast.

What was your primary form of communication with WislaCode Solutions?

• Virtual Meeting
• Email or Messaging App

What did you find most impressive or unique about this company?

What stood out was how WislaCode Solutions handled the unglamorous parts: retries, fallbacks, and error handling for unstable networks, which is exactly where payment integrations usually break in production. Communication was transparent throughout, and we always knew where the project stood.

Are there any areas for improvement or something WislaCode Solutions could have done differently?

Nothing
