Business Engine: End-to-End BSS/OSS for Fiber Networks
Last updated: June 2026 | COS Systems
COS Business Engine is the core BSS/OSS platform for fiber network operators. It covers the full subscriber lifecycle: demand capture, marketplace, order orchestration, provisioning, billing, and the customer portal — and supports retail, open access, and hybrid business models directly. COS Wholesale Engine adds the multi-ISP orchestration and wholesale billing layer for operators managing multiple service providers on shared infrastructure. COS FSM integrates as the field execution layer, connecting installation scheduling directly to activation outcomes. COS Prospector supports pre-build demand aggregation and address-level expansion planning upstream of the operational workflow.
Built for ISP, wholesale, and open access business models — with an API-first architecture for easy integration.

From interest to active service — one automated flow
Business Engine connects your commercial workflow to your operational workflow so every step is predictable, trackable, and scalable.
1) Capture demand
Collect surveys and signups to guide rollout decisions and improve take-rates.→
2) Sell through a marketplace
Publish services with rules by group, area, or customer segment and allow subscribers to self-order.3) Provision automatically
Orders trigger provisioning and activate services with minimal manual handling.→
4) Bill and report with confidence
Billing aligns with activation status and lifecycle events — reducing leakage and disputes.End-to-end automation is what lets you scale the network without scaling headcount.

Why operators choose an integrated BSS/OSS for FTTH
Most operators don't fail because they lack funding or network plans — they struggle because operations don't scale. Business Engine standardizes the "business of fiber" so growth doesn't require proportional headcount growth.

In Use Across North America
Fiber First migrated its multi-state ISP operations onto COS Business Engine and COS FSM after outgrowing its previous BSS/OSS. Sales teams now see real-time serviceability data and book broadband installations at the point of sale — across markets running on Ubiquiti open access infrastructure. California markets have been successfully migrated; tens of thousands of subscribers across remaining markets are next.
PRIME FiBER selected COS Wholesale Engine for its open access fiber expansion in Sun City, Arizona, powering wholesale operations and AT&T integration at scale. "COS Wholesale Engine gives us the operational foundation to efficiently support our wholesale model and automate complex partner interactions," said Rob Johnson, CTO of PRIME FiBER.
Frequently Asked Questions
Common questions about COS Business Engine and BSS/OSS for fiber networks.
What is COS Business Engine?
COS Business Engine is a cloud-hosted BSS/OSS platform for fiber network operators. It covers the full subscriber lifecycle — demand capture, marketplace, order orchestration, provisioning, billing, and the customer portal — in one integrated system. It supports retail ISP, open access, and hybrid broadband business models, and is built on an API-first architecture for integration with provisioning vendors, field systems, and third-party platforms.
What is a BSS/OSS platform for fiber networks?
A BSS/OSS platform combines the commercial and operational systems required to run a broadband network. BSS — Business Support Systems — covers subscriber management, ordering, billing, and the customer portal. OSS — Operations Support Systems — covers provisioning, service lifecycle, and network visibility. For FTTH operators, an integrated BSS/OSS eliminates the handoff gaps between commercial and operational workflows, reducing manual effort and time-to-revenue.
Does COS Business Engine support open access fiber networks?
Yes. COS Business Engine supports open access operations directly, including multi-provider marketplaces, partner access to service and order data, and settlement-ready billing reporting. For operators managing multiple ISPs on shared infrastructure who require full multi-ISP orchestration and automated wholesale invoicing between the network owner and service providers, COS Wholesale Engine provides that layer.
What is the difference between COS Business Engine and COS Wholesale Engine?
COS Business Engine is the core BSS/OSS platform for operators serving subscribers directly — as a retail ISP, an open access operator, or both. It handles the full customer lifecycle including ordering, provisioning, billing, and the customer portal. COS Wholesale Engine is designed for operators who own the infrastructure and provide wholesale access to multiple ISPs — it manages ISP onboarding, wholesale invoicing, and multi-provider network orchestration. Both products can be deployed together for operators running hybrid retail and wholesale models on the same or separate markets.
How does automated billing work in COS Business Engine?
Billing in COS Business Engine is aligned to service activation and deactivation events, not manual inputs. This means invoices reflect actual service delivery status, eliminating revenue leakage from unbilled activations or delayed cancellations. Billing runs automatically on a configured cycle with no manual trigger required. For operators running wholesale or open access models, Business Engine also produces settlement-ready wholesale billing reports that can feed directly into wholesale invoicing workflows.
Does COS Business Engine include zero-touch provisioning?
Yes. COS Business Engine connects subscriber orders directly to provisioning actions via integrations with network equipment vendors including Adtran, Nokia, and Calix. When a subscriber order is confirmed, the provisioning workflow triggers automatically — activating the service without manual intervention. This zero-touch flow reduces time-to-activation, removes the risk of manual provisioning errors, and scales without requiring additional operations headcount.
Do I need COS FSM to use COS Business Engine?
No. COS FSM is a separate product that can be deployed standalone or integrated with COS Business Engine. Business Engine manages the subscriber lifecycle end-to-end without FSM. When COS FSM is integrated, it extends that automation into field execution — connecting a completed subscriber order to a scheduled installation with no manual handoff between commercial and field operations teams.
What types of fiber operators use COS Business Engine?
COS Business Engine is used by retail ISPs, open access network operators, municipal and utility fiber providers, and hybrid operators running both retail and wholesale services. Deployments span North America, the Nordics, and Europe. The platform is designed for operators at any scale — from community fiber networks in early build phases to multi-market ISPs with large subscriber bases requiring high-volume automation across ordering, provisioning, and billing.
How does COS Business Engine integrate with existing systems?
COS Business Engine is built on an API-first architecture and supports integration with provisioning vendors (Adtran, Nokia, Calix), network documentation tools (Vetro FiberMap), billing platforms (Stripe), CRM and support tools (GOCare), and other BSS/OSS systems via REST APIs. COS can manage integration delivery, or hand off to the operator's own technical team. The platform is designed to work alongside existing systems where integration adds value, and as a standalone platform where it does not.
