Why Brussels companies invest in software
With eU institutions, associations and financial infrastructure, businesses in Brussels face growing pressure to digitise operations, serve customers online and integrate with partners. The most common requests we receive from Brussels are digital wallet & E-Wallet app, telemedicine & patient app and crypto payment gateway.
Because Brussels draws talent from ULB and VUB, many companies here run lean in-house teams and use NNT Software to add product engineering, QA, DevOps or AI skills on demand — with delivery scheduled around CET working hours.

- Start with the workflows that matter most to eU institutions — usually top-ups & cash-out and virtual cards.
- Meet stakeholders in the European Quarter or online for a one-to-two-week discovery workshop.
- Plan hosting and integrations around brussels Airport and the CET working day.
- Combine your local team — often hired from ULB — with NNT engineers for design, development and QA.

What Brussels businesses need from software
The core economy of Brussels
Businesses here typically need reliable, integrated software that removes manual work and scales with growth, and measure progress on manual hours saved, error rate and customer response time.
Payments infrastructure in Brussels
Payments infrastructure companies typically need high approval rates, local payment methods, payouts and automated reconciliation, and measure progress on authorisation rate, cost per transaction and payout time.
Pharma in Brussels
Pharma companies typically need protected patient data, interoperability with clinical systems and validated, auditable workflows, and measure progress on appointment no-show rate, clinician admin time and data-sharing turnaround.
Logistics in Brussels
Logistics companies typically need live shipment visibility, warehouse accuracy, carrier integrations and digital proof of delivery, and measure progress on on-time delivery rate, cost per drop and warehouse pick accuracy.
Digital Wallet & E-Wallet App for Brussels
A digital wallet app stores money or payment credentials so users can pay, transfer and top up from their phone. For Brussels clients we usually begin with virtual cards (issuing via card-programme partners) and bill payments, then add ledger & reconciliation and kyc tiers. Pricing is set as per your requirements and budget.

A telemedicine platform lets patients book and attend video consultations, receive prescriptions and pay online. For Brussels clients we usually begin with ehr integration (hL7/FHIR record sync) and payments & insurance, then add remote monitoring and booking. Typical first release: 10–16 weeks.
Crypto Payment Gateway for Brussels
A crypto payment gateway lets merchants accept Bitcoin, Ethereum and stablecoins such as USDT and USDC, with instant conversion to fiat if required. For Brussels clients we usually begin with merchant onboarding (kYB, API keys and settlement preferences) and checkout & plugins, then add stablecoin rails and auto-conversion. Typical first release: 10–16 weeks.
Remittance & Money Transfer App for Brussels
A remittance app lets users send money abroad to bank accounts, mobile wallets or cash-pickup points.

Typical first release: 14–22 weeks.
Example project in Brussels
Picture a payments infrastructure business in Brussels that needs a digital wallet & E-Wallet app. Discovery and a clickable prototype take about two weeks; the first release — top-ups & cash-out, virtual cards and bill payments — follows in 12–20 weeks.
Customers pay with Payconiq, personal data is handled under EU GDPR, the product is hosted on Google Cloud St. Ghislain, and the team reviews authorisation rate and cost per transaction every month.
