COS Wholesale Engine

The API-first Open Access Network Orchestrator for multi-ISP,
multi-vendor, and M&A-ready operations.

COS Wholesale Engine is an API-first Open Access Network Orchestrator that allows an infrastructure operator to manage several Service Providers on a single shared infrastructure, with full automation and subscriber visibility. As wholesale broadband software, it covers the full wholesale layer: service locations, multi-vendor provisioning, cross-operator ticketing, and per-ISP invoicing.

API-first Open Access Network Orchestrator

Built for wholesale. Ready for Open Access and M&A

Standards-oriented integration layer (REST APIs), enabling ISPs to plug in their own BSS/OSS and support/NOC systems.

This solution is also a strong fit for mergers and acquisitions (M&As), serving as a normalization layer across disparate tech stacks, allowing operators to integrate acquired networks faster and more cost-effectively, and to keep acquired ISPs’ customer-facing tech stacks in place for migration over time.

What COS Wholesale Engine does

A single orchestration layer for locations, services, provisioning, ticketing, and wholesale billing

  • Service locations & build lifecycle

    Areas, address/service locations, and deliverability rules are provided as the single source of truth that ISP partners use to sell and operate.

  • Zero-touch provisioning & multi-vendor support

    EMS/NMS integrations allow multiple EMSs to be controlled in parallel—ideal for operators using several technology vendors or for avoiding rip-and-replace in M&A scenarios.

  • Disruptions & ticketing for cross-organization collaboration

    Built for fast incident handling, escalation, and communication between the network operator and participating ISPs.

  • Standardized integration layer (APIs)

    ISPs’ BSS/OSS tech stacks integrate via a standards-oriented integration layer (REST), with straightforward API extensions when needed.

  • Wholesale broadband billing with automatic accuracy

    Billing is generated from live order activations to eliminate disputes and “free riders.” Data is aggregated monthly per ISP

M&A Readiness

ISP Consolidation Is Accelerating. The Bottleneck Is Usually the BSS/OSS Stack.

Private equity is rolling up regional ISPs. Municipalities are acquiring last-mile assets. Tier 1 operators are entering new markets through acquisition rather than greenfield build. Every deal creates the same operational problem: two networks, two subscriber bases, two billing systems, and one deadline to make it work.

The default answer is rip-and-replace. The timeline is 12 to 18 months. The plans are usually too optimistic. And the revenue risk is real: forced migrations trigger churn at exactly the moment synergies are supposed to emerge.

The smarter path is to separate where you take cost from where you protect revenue.

One orchestration layer. No forced migration.

COS Wholesale Engine sits above acquired networks as a normalization layer. The acquired ISP keeps its brand and customer portal. Its billing stack keeps running. COS manages service locations, provisioning, wholesale billing, and cross-organization incident handling across every entity in the portfolio.

Multiple ISPs and brands operate on the same infrastructure simultaneously. Multiple EMS/NMS systems run in parallel via a standards-oriented REST API. System consolidation happens in controlled phases — on your timetable, not a migration vendor’s.

For ISP Executives

Acquired customers stay on a known experience. Churn risk during the transition window drops. Local brand equity — built over years — stays intact and keeps generating revenue.

For Operations and Build Teams

Multiple EMS/NMS systems run in parallel under one orchestration layer. Multi-vendor infrastructure is an operational asset, not a liability. No rip-and-replace required to unify NOC and field operations.

For Investors and Portfolio Operators

Profitability rises twice: first from revenue retention and cross-sell across all brands, then from phased system consolidation that methodically lowers unit costs. Wholesale billing is generated from live activations — auditable and accurate from day one.

Why choose Wholesale Engine?

Why Operators Choose Wholesale Engine

  • Separation of Infrastructure and Customer Operations

    Traditional telco stacks are vertically integrated. COS Wholesale Engine enables clean separation while keeping both sides fully synchronized—giving operators agility and scalability operators have never experienced before.

  • Open Access / Wholesale Readiness

    Multiple ISP partners can operate on the same infrastructure with full visibility and full network integration. This boosts take-rates both in multi-brand markets and new Open Access builds.

  • Enables Cross-Selling

    Multiple ISPs can be active in any market with no risk of syncing errors or clashes. In M&A scenarios, all brands can remain active, maximizing take-rates across selected or all markets.

  • Reduced Time to Market

    By allowing most systems to remain intact during M&A consolidation, integration time is dramatically reduced. BSS systems can be consolidated gradually if desired.

  • Hardware-Agnostic Automation

    Supports major vendors and multi-vendor networks, reducing lock-in and allowing “rip-and-replace-free” mergers.

  • Automated Network Operations

    Operators gain full control of network operations without needing to replace customer-facing BSS systems.

  • No Wholesale Billing Disputes

    Clear, auditable wholesale invoicing aligned to activations eliminates billing friction.

Frequently Asked Questions

What is COS Wholesale Engine?

COS Wholesale Engine is a BSS/OSS platform for infrastructure operators running open access networks, wholesale fiber, or multi-ISP environments. It manages service locations, zero-touch provisioning, cross-operator ticketing, and wholesale billing across multiple service providers on a single shared infrastructure — via a standards-oriented REST API that connects to each ISP’s existing tech stack.

How does COS Wholesale Engine support ISP mergers and acquisitions?

COS Wholesale Engine acts as a normalization layer across disparate BSS/OSS stacks. In an M&A scenario, the acquired ISP keeps its customer portal and billing systems running. COS sits above them as the operational spine — handling provisioning, service locations, and wholesale billing across all entities. BSS consolidation happens in controlled phases, on the operator’s timeline, which eliminates the churn and revenue risk that comes with forced Day-1 migrations.

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

COS Business Engine is designed for retail ISPs managing their own subscriber base — it covers the full customer lifecycle from signup through billing and support. COS Wholesale Engine is designed for infrastructure operators who provide network access to multiple ISPs. It manages the wholesale layer: service locations, multi-provider provisioning, cross-operator ticketing, and wholesale invoicing. Operators typically run one or the other based on their business model, though some open access operators use both.

Does COS Wholesale Engine require replacing existing ISP billing systems?

No. COS Wholesale Engine connects to existing ISP BSS/OSS platforms via REST API. Each service provider on the network retains its own billing stack and customer-facing systems. COS manages the infrastructure and wholesale layer above them. This is specifically designed for M&A scenarios and multi-vendor environments where rip-and-replace is operationally and financially impractical.

How does wholesale billing work in COS Wholesale Engine?

Wholesale billing is generated directly from live order activations, not from manual data entry or reconciliation. This means invoices are accurate by default and aggregated monthly per ISP. There are no billing disputes caused by timing gaps between activation and billing records — the data source is the same for both.

What network technologies and vendors does COS Wholesale Engine support?
