OUR SOLUTION

Fiber Network Software —
for Open Access, Wholesale, and ISP Operation

COS Systems provides fiber network software for ISPs, open access infrastructure owners, municipalities, and wholesale carriers. The product suite covers the full operational lifecycle: demand aggregation and pre-build planning (COS Prospector), subscriber management and billing (COS Business Engine), wholesale and open access operations (COS Wholesale Engine), and field service management (COS FSM). COS supports retail, open access, wholesale, and hybrid broadband business models. The platform is cloud-hosted, API-first, and designed for automation across commercial, operational, and field workflows.

The four COS products operate as a unified suite across three layers of fiber network operations: pre-build and demand aggregation (COS Prospector), subscriber and commercial operations (COS Business Engine), and wholesale and multi-ISP orchestration (COS Wholesale Engine). COS FSM integrates across all layers to manage field execution from first install through ongoing maintenance. Operators deploy products individually or in combination depending on their business model.

Four Critical Challenges. One Integrated Solution:

COS delivers end-to-end automation across the entire fiber lifecycle for traditional ISP models, Open Access, and hybrid approaches.

Which Customer Groups Do We Serve?

COS Systems is purpose-built for fiber network operators worldwide, with active deployments across North America, the Nordics, and Europe, including customers in the United States, Sweden, Finland, and Austria. The platform serves ISPs, open access network owners, wholesale carriers, and municipal broadband providers that run open access, wholesale, retail, and hybrid broadband business models. COS supports networks at all stages of maturity: from greenfield municipal builds through established multi-market ISPs scaling toward automation and zero-touch provisioning.

Municipalities & Utilities

Cities, counties, and utility providers building and operating fiber networks for their communities — typically using an open access model where multiple ISPs compete on shared infrastructure.

Open Access Network Operators

Neutral host operators and infrastructure owners who provide wholesale fiber access to multiple ISPs and need software to manage onboarding, billing, and operations across service providers.

Internet Service Providers (ISPs)

Internet service providers of all sizes — from regional and community operators to larger multi-market ISPs — who serve subscribers directly on their own or third-party fiber infrastructure and need an integrated BSS/OSS to automate orders, provisioning, billing, and field operations at scale.

Wholesale Fiber Carriers

Infrastructure owners and wholesale carriers who provide layer 2 or layer 3 access to multiple ISPs and need automated wholesale billing, revenue assurance, and multi-provider operations management.

Hybrid Retail & Wholesale Operators

Operators running both retail ISP services and wholesale open access on the same or different markets — using COS Business Engine and COS Wholesale Engine together in a unified platform.

Managed Service Providers

Partners and managed service providers who operate fiber networks on behalf of municipalities or infrastructure owners, and need a software platform that supports full end-to-end operations across multiple client networks.

Choosing Your Core Engine

Whether you operate as a retail ISP, a wholesale infrastructure owner, or both in different markets, COS gives you a clear path:

Choose COS Business Engine if you:

  • Operate as a retail ISP (single or multi-brand)

  • Want a complete BSS/OSS platform including CRM, marketplace, billing, provisioning, and automation

  • Need zero-touch provisioning and automated workflows from order to activation

  • Want to combine retail and wholesale operations in one unified system

Choose COS Wholesale Engine if you:

  • Operate open access or wholesale-only infrastructure

  • Need to onboard multiple ISPs and brands on shared fiber or FWA

  • Want to keep ISP BSS/OSS stacks in place and orchestrate everything via APIs

COS FSM can be added to both to standardize and automate field operations across your own and your partners’ crews.

Integrations and API:s

COS operates on an API-first architecture. Where integrations add value, the COS platform supports full integration with provisioning vendors, billing platforms, documentation tools, and CRM systems — and functions equally well as a standalone platform when no external stack is required. Supported integrations include provisioning vendors such as Adtran, Nokia, and Calix; network documentation tools such as Vetro FiberMap and IQGeo; billing platforms such as Stripe; and CRM and support tools such as GOCare. Integration delivery can be managed by COS or handed off to the operator’s own team.

Partnerships to establish your end-to-end process

COS maintains an ecosystem of technology and service partners across provisioning hardware, network documentation, billing infrastructure, and managed services. This includes partnerships with vendors whose products integrate directly with COS at the API level, and with managed service providers who operate COS-powered networks on behalf of municipalities and infrastructure owners. Where a partner delivers part of the end-to-end workflow — from survey and design through to subscriber activation — the COS platform is built to connect with them without requiring custom development.

Frequently Asked Questions

Everything you need to know about COS Systems and fiber network software.

What does COS Systems do?
+

COS Systems provides software for fiber network operators, covering the full network lifecycle from demand discovery and build planning through to subscriber management, billing, wholesale operations, and field execution. COS is purpose-built for open access, wholesale, and municipal broadband business models.

What products does COS Systems offer?
+

COS Systems offers four products: COS Business Engine (BSS/OSS for retail fiber operators), COS Wholesale Engine (wholesale billing and operations for open access networks), COS FSM (field service management for fiber installation and maintenance), and COS Prospector (demand aggregation and network expansion planning).

What is an open access fiber network?
+

An open access fiber network is infrastructure owned by one entity — typically a municipality, utility, or neutral host — that multiple competing ISPs can use to deliver services to subscribers. The network owner provides the physical layer; ISPs compete on service, price, and customer experience. COS Systems specializes in software for operating and monetizing this model.

What software do open access fiber networks use?
+

Open access fiber networks typically require software that can manage multiple ISPs on shared infrastructure, handle wholesale billing between the network owner and service providers, automate subscriber provisioning per ISP, and produce clean revenue reporting. COS Wholesale Engine is designed specifically for this use case.

How do fiber operators manage field service and installations?
+

Fiber operators use field service management (FSM) software to schedule technicians, dispatch crews, manage work orders, and handle customer appointment booking. COS FSM provides skill-based scheduling, self-service appointment booking for subscribers, and route optimization for technicians — and integrates directly with COS Business Engine so that a completed order triggers a scheduled installation automatically.

How does wholesale billing work for open access networks?
+

In a wholesale open access model, the infrastructure owner charges ISPs for access to the network, while ISPs bill their own subscribers separately. COS Wholesale Engine automates this by tracking usage per ISP, generating wholesale invoices, and keeping billing and reporting clean across multiple service providers — without requiring ISPs to replace their own BSS/OSS systems.

What is the difference between COS Business Engine and COS Wholesale Engine?
+

COS Business Engine is for operators who serve subscribers directly as a retail ISP — it handles the full customer lifecycle including CRM, marketplace, provisioning, billing, and support. COS Wholesale Engine is for operators who own the infrastructure and wholesale access to multiple ISPs — it manages ISP onboarding, wholesale billing, and multi-provider operations. Both can be combined for operators running hybrid retail and wholesale models.

Can COS FSM be used independently, or does it require COS Business Engine?
+

COS FSM can be deployed as a standalone field service management platform or integrated with COS Business Engine or COS Wholesale Engine. In standalone mode it manages scheduling, dispatch, and work orders. When integrated with Business Engine, it creates a zero-touch flow from customer sign-up to completed installation with no manual handoff.

What types of operators does COS Systems serve?
+

COS Systems serves fiber network operators including municipal and utility fiber providers, regional and community ISPs, open access infrastructure owners, wholesale fiber carriers, and operators managing hybrid retail and wholesale business models.

How does COS Prospector support network expansion?
+

COS Prospector gives operators address-level demand intelligence to prioritize where to build. Sales teams and field staff can qualify addresses, check build zones, and sign up customers on the spot. When combined with COS FSM, a new subscriber can have an installation scheduled at the point of sale — connecting demand aggregation directly to deployment.
