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.
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 and monitoring during the coverage window expressly included in the accepted scope. 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: delivery timing for cabling, WiFi, POS, printers, telephony, signage and cameras is documented after the site, access, scope and assigned resource are confirmed.
- 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.
