The dominant factor difference between livewire and vue is not technology — it is almost always uncertainty. Every open question in the requirements is converted into a buffer in the estimate. A team that cannot see the edge cases must assume the more expensive option. Investing a few days in requirements work often reduces the final cost far more than haggling over hourly rates.

Connections to other systems tend to be the second big multiplier. A form that saves data is easy to estimate; the same feature wired into a legacy ERP is not. The cost sits in the other system: rate limits and sandbox access, slow approval cycles, fields that mean something different on each side. Ask each bidder to list every external system, as this is the usual source of overruns.

Non-functional requirements silently change the number. A tool used by a small internal team is a very different build from the same functionality handling public traffic. Audit and compliance requirements, uptime targets, scalability, traceability and localisation add real engineering time. State them early or expect them to arrive later as change requests.

The team you are quoted changes the arithmetic. An hourly rate says little on its own: a senior engineer at a premium rate frequently turns out to be cheaper overall than a pair of junior hire laravel developers who require constant review. Also ask which is better laravel or .net roles are billed: project management, QA, DevOps and design are legitimate costs, but they should be named rather than hidden inside a blended rate.

The quoted figure is never what you will actually spend. Budget for cloud costs, subscriptions and web app development services licences, logging and alerting and a change budget annually. A common working assumption is that software in active use consumes a noticeable fraction of the initial investment per year for updates, security patches and small improvements. Ignoring this has always been the classic mistake.
