What WT does

WT SRL (also styled WT SRLS) is an Italian private software company headquartered in Patti, Sicily, that builds vertical SaaS for the domestic ISP/WISP telecommunications market. Its flagship product, WT-GEST, is a management platform purpose-built for Internet Service Providers and Wireless ISPs, integrating recurring billing (monthly to annual cycles plus custom periodicities), automated invoice generation, postal bollettino 896 payment slips, SEPA Direct Debit processing, payment reconciliation from Poste Italiane and bank channels, reseller/agent commission calculation, contract and CPE configuration, and Radius-driven automatic service suspension and reactivation for delinquent customers. The platform also integrates with TIM's NGASP API for real-time bitstream diagnostics on ADSL/FTTC/FTTH lines and with A2Billing for VoIP CDR import.

Complementing WT-GEST, WT operates FE-HUB-WS, an electronic invoicing API and web services platform that handles Italian FatturaPA-compliant XML invoice submission, reception, and digital preservation via the SDI (Sistema di Interscambio), with automatic digital signature, multi-company support, and white-label branding for software houses and system integrators. The portfolio extends further into a standalone browser-based Piattaforma di Fatturazione and a combined web+API Hub Fatturazione tier, broadening monetization beyond the ISP/WISP vertical.

WT monetizes through customized annual subscriptions for WT-GEST, usage-based prepaid invoice packages for FE-HUB-WS, professional services for custom development and integration, and channel partner licenses for wholesale resellers running multi-tenant operations. Distribution runs through a sales-led direct motion (demo-driven website funnel), a domestic reseller/wholesale channel, and a global API/developer channel targeting software houses seeking embedded invoicing capability. The customer base is concentrated in the Italian mid-market ISP/WISP segment, with no disclosed enterprise anchors, no disclosed revenue or funding, and an 11-50 employee footprint.

WT competitors and assessment

Company assessment

Emerging players

Fatture in Cloud: Fatture in Cloud is a leading Italian SaaS for electronic invoicing and accounting, directly competing with FE-HUB-WS in the SDI-integrated invoicing market and a potential substitute for WT's invoicing module.
UISP (Ubiquiti): UISP is Ubiquiti's ISP/WISP management platform combining network device control with billing and customer management — overlapping with WT's ISP operator toolset though tied to Ubiquiti hardware.

Broad incumbents

TeamSystem: TeamSystem is a large Italian software house offering accounting, invoicing, HR, and ERP solutions to Italian SMBs and businesses — competing broadly with FE-HUB-WS and potentially encroaching on ISP-side billing workflows.
Zucchetti: Zucchetti is one of the largest Italian software providers spanning ERP, HR, and accounting — a broad incumbent whose invoicing and billing modules overlap with WT's electronic invoicing and customer management capabilities.
InfoCert (Tinexta Group): InfoCert is a leading Italian digital trust and electronic invoicing provider (Digital Hub) integrated with SDI — competing directly with FE-HUB-WS in certified e-invoicing services for Italian businesses.
Aruba: Aruba is a major Italian cloud, hosting, and digital services provider including PEC and electronic invoicing — competing broadly with FE-HUB-WS in SDI-integrated invoicing and with broader ISP-adjacent services.

Direct peers

Splynx: Splynx is a billing and management platform purpose-built for ISPs and WISPs, offering Radius integration, invoicing, and customer management — directly comparable to WT-GEST's core functionality, though operating globally rather than Italy-only.
ViSP.net (Virtual ISP Software): ViSP is billing and management software targeted at ISPs/WISPs with Radius integration and customer lifecycle management — directly comparable in category and customer type to WT-GEST.
Powercode: Powercode provides billing and management software for ISPs and WISPs, including provisioning, ticketing, and Radius integration — directly overlapping with WT-GEST's ISP operator focus.
Sonar (by Stickman Ventures): Sonar is an ISP billing, network management, and CRM platform for internet service providers. Comparable to WT-GEST in serving ISP/WISP operations with billing, provisioning, and customer workflows.
