What are the deployment options for an ERP system ?

When considering deployment options for an ERP system, Lighthouse gives you Choice: On-premise, hosted or Cloud ERP deployment. Providing three deployment options gives you the flexibility to choose the best solution for your company, and your budget.


Higher initial cost of ownership due to upfront cost of hardware and software acquisition, but the lowest long-term cost of ownership because software license is perpetual.


Lower initial investment as hardware hosting costs are spread over time and lower long-term cost because software license is perpetual. Lowers in-house hardware IT footprint and eliminates issues with end-of-life hardware.


Lowest cost of initial investment because software and hardware costs are spread over time, but highest long-term costs because software licenses are leased, not owned in perpetuity.
