For large retail enterprises, every store, system and customer-facing service depends on the network operating effectively. But as organisations modernise their connectivity environments through SD-WAN and other network transformation initiatives, cost complexity can increase quickly. Multiple sites, providers, contracts, billing lines and SLA commitments make it difficult to understand where money is being spent, where value is being lost and which suppliers are performing as expected. This was the challenge facing a leading retail enterprise managing SD-WAN and connectivity costs across more than 900 stores. The organisation needed a more governed way to manage network costs, improve supplier accountability and recover value from its connectivity environment. Key challenges included limited visibility across distributed network spend, complex supplier billing, missed SLA credit opportunities and the need to reduce cost leakage across a critical transformation programme. # What our client achieved with OneView and 1Nebula → Governed SD-WAN costs across more than 900 stores → Reduced network costs by up to 40% → Recovered millions in SLA credits → Improved supplier accountability and performance visibility → Identified billing anomalies and unnecessary spend → Strengthened financial control across network and connectivity services → Protected the financial value of a major network modernisation initiative [DOWNLOAD THE FULL CASE STUDY](https://www.1nebula.com/hubfs/OV_0061_Banking_Voice_Case_Study_V3.pdf) #### Top posts [![](https://www.1nebula.com/hubfs/ON_0064_SOC2_V1.png)](https://www.1nebula.com/blog/1nebula-soc-2-type-ii-attestation/) ##### [1Nebula Achieves SOC 2 Type II Attestation](https://www.1nebula.com/blog/1nebula-soc-2-type-ii-attestation/) 1Nebula is proud to announce that it has achieved **SOC 2 Type II...** [![](https://www.1nebula.com/hubfs/1Nebula_Why_Every_Team_Needs_a_Fourth_Question_V1.png)](https://www.1nebula.com/blog/why-every-team-needs-a-fourth-question) ##### [Why Every Team Needs a Fourth Question](https://www.1nebula.com/blog/why-every-team-needs-a-fourth-question) “Stop, Start, Continue” has run team retrospectives for a decade....
