Retail chains, franchises, commercial networks: the IT challenge in retail across Spain and Portugal is brutally operational. When the POS goes down in a store during Saturday's peak, there is no technical debate — there are customers in line and lost sales. When the payment gateway turns intermittent during the Christmas campaign, every minute counts in revenue.
Impulso Tecnológico has spent over 20 years deploying IT infrastructure in retail chains across the Iberian Peninsula. Our approach combines replicable architecture, strict SLAs for commercial-critical systems, and on-site support when needed at any store in Spain or Portugal.
Typical challenges in retail
- Unstable POS during commercial peaks: outages on Black Friday, sales or Christmas campaigns. Intermittent payment gateway, silent ERP integration failures.
- Unreliable store connectivity: links without 4G/5G backup, without proactive monitoring. When the carrier fails, the store finds out when the POS stops billing.
- Ungoverned customer WiFi: a single WiFi for corporate, staff personal devices, and guest courtesy. No segmentation, no filtering, no captive portal.
- Slow openings: a new store takes 6 weeks to be IT-operational when the commercial calendar asks for 3.
- Inconsistent customer-experience tech: digital signage, beacons, self-service kiosks that work in one store and not in another.
- Loss prevention without central visibility: video surveillance with local DVRs, no integration, no cross-store alerts.
How we tackle it at Impulso
We design retail-specific IT with SLA differentiated by criticality:
- POS with critical SLA: real-time payment gateway monitoring, proactive alerts before the store manager calls, preferential vendor escalation, <15 min response during commercial hours.
- Redundant store connectivity: primary fiber + 4G/5G managed backup, automatic failover, 24/7 monitoring. When there's an outage, we contact the carrier before the store notices.
- Segmented Aruba WiFi: three SSIDs per store (corporate for POS/back-office, guest courtesy with captive portal, IoT for signage). QoS prioritization for POS. Central Aruba Central management.
- Opening playbook: new store IT-ready in 3 weeks from contract signature. Cabling, WiFi, POS, printers, telephony, signage, Verkada cameras — all replicable by checklist.
- Managed Verkada surveillance: cloud-native cameras with event detection, integration with the sales system, cross-store alerts accessible from HQ. GDPR compliance for commercial-zone recording.
- Extended support during campaigns: helpdesk reinforcement during critical periods (Black Friday, sales, holidays), with technicians available for express dispatch on critical POS incidents.
Regulatory compliance in retail
- PCI-DSS: applies to any merchant processing cards. Mandatory network segmentation, audited technical controls, periodic evidence. Impulso prepares and maintains the PCI scope of the store network.
- GDPR and local data laws (LOPDGDD in Spain, Law 58/2019 in Portugal): particularly sensitive for loyalty programs (newsletters, points, purchase profiling). AEPD and CNPD inspections in retail have risen in recent years.
- Commercial video surveillance: mandatory signage, processing register, maximum retention periods (30 days unless justified). Verkada simplifies documentary compliance.
- Electronic invoicing: TicketBAI / Veri*factu in Spain, e-Fatura in Portugal — POS integration and real-time validation with AEAT / AT.
