How Much Does Computer Aided Dispatch Software Cost in 2026?

Three bands, and most centers should be looking at the cheapest one

Before the line items, the uncomfortable recommendation. For most communications centers, our advice is not to build the dispatch core at all. Build the layer around the CAD you already run. A dispatch core is a continuously operating, life safety system with a support obligation that outlives whoever signs the contract, and replacing one that basically works is rarely the best use of a capital request. The band that pays is the one nobody quotes you, because the incumbent vendor prices those pieces as change orders and your integrator prices them as a whole new system.

The wrapper layer, $90,000 to $220,000. Everything your CAD will not do, built alongside it.

• Real time data feed out of the CAD, $20,000 to $50,000. Your own incident and unit status data, out of the vendor's database and into something you can query, in seconds rather than in a nightly report. Every other item on this list depends on it.
• Interfaces the vendor quotes as change orders, $25,000 to $70,000. The records system, the fire RMS, the ePCR, an AVL feed, station alerting. Each one is its own small project, and the price varies more with the far end than with the CAD end.
• Dispatcher tools the vendor will not build, $20,000 to $50,000. The second screen your dispatchers built out of sticky notes and a shared spreadsheet: premise hazard lookups, the tow rotation, the on call list, the unit availability board that matches how you actually deploy.
• Operational reporting and regional views, $15,000 to $40,000. Response time analysis your chiefs trust because the definitions are yours, not the vendor's.

The custom dispatch core, $180,000 to $400,000. Call taking and incident entry at $35,000 to $70,000. Run cards and the unit recommendation engine at $40,000 to $85,000, which is the piece that genuinely does not fit a product if your deployment model is unusual. The status model and unit tracking at $25,000 to $55,000. Mapping with AVL at $30,000 to $70,000. The dispatcher console at $30,000 to $65,000. Redundancy, failover and a backup center posture at $25,000 to $60,000.

The full multi agency CAD, $500,000 to $1.2M. Adds mobile data for field units, station alerting integration, the ANI and ALI feed, cross agency boundary and mutual aid logic, the interface set to records, fire records and ePCR, and a support model that answers the phone at 3am.

What specifically drives the range up

• Disciplines, not agencies. Three police agencies on one system is largely configuration. Police plus fire plus EMS is three different status models, three different unit recommendation logics and three different definitions of when a call is closed. Adding a second discipline typically adds 35 to 50 percent, not 10.
• The interface count, at $25,000 to $70,000 each. Records, fire records, ePCR, station alerting, AVL, the state message switch, mapping data. Six interfaces is a $200,000 line item on its own, and your other vendors charge for their side. Get every one of those quotes before you set a project budget.
• Continuous availability. No maintenance window means redundant everything, tested failover, a backup center that is actually exercised, and deployment practices that let you ship without dropping a call. This is $25,000 to $60,000 of engineering in the build and a permanent operating cost afterwards.
• State message switch access. Reaching the state and national law enforcement databases from your console carries security, auditing and certification requirements that add $30,000 to $80,000 and a recurring audit obligation.
• Mobile data in vehicles. Field units running on cellular in dead zones need offline behaviour, message queuing and a status model that reconciles when the unit comes back. Budget $60,000 to $150,000 and treat it as its own phase.

What pulls the number down

• Keeping the core and buying the layer. This is a $400,000 decision. It also removes the risk that the hardest system in the building is now maintained by whoever answers your support email.
• One discipline in phase one. Fire only or police only, with the other agencies staying where they are until the model is proven live.
• Keeping the vendor's mapping. Mapping and AVL is $30,000 to $70,000 that you may not need to spend twice.
• Deferring mobile. Dispatch first, field units later. The center is where the pain is.
• Sequencing interfaces by pain. Build the two that dispatchers work around daily. The other four can wait a year and some of them turn out not to matter.

A worked example: a consolidated center taking 180,000 calls a year

Three police agencies, two fire departments, one aging CAD with a usable database but no API worth the name, and a records system the vendor quoted $85,000 to interface with on a nine month queue.

• Discovery, status model documentation and read replica design: $14,000
• Real time data feed out of the CAD, change data capture off a replica: $38,000
• Records system interface, built directly rather than through the CAD vendor: $34,000
• Fire records and ePCR feed: $27,000
• Dispatcher second screen: premise hazards, tow rotation, on call lists, availability board: $41,000
• Station alerting interface for the two fire departments: $22,000
• Response time reporting with the chiefs' own definitions: $19,000
• Redundant hosting posture, failover test plan and runbooks: $16,000
• Training across four shifts and a phased cutover with no downtime: $11,000

That totals $222,000, just above the wrapper band, and it delivers the records interface for $34,000 that the CAD vendor priced at $85,000 with a nine month wait. Replacing the core to get the same outcomes would have started at $500,000 and put a life safety system on a new codebase. This is the arithmetic most centers never see laid out, because the incumbent has no reason to show it to you.

How the spend lands across the calendar

Four to seven months for a wrapper layer, six to ten for a dispatch core, twelve to twenty four for a full multi agency system. The wrapper spends like this.

• Weeks 1 to 4, roughly 12 percent. Documenting the status model and run card logic that currently exists only in the heads of three senior dispatchers, and getting read access to the CAD database agreed in writing.
• Weeks 3 to 12, roughly 35 percent. The real time feed. Everything downstream is blocked on this, so it goes first and it gets the strongest engineer.
• Weeks 10 to 22, roughly 38 percent. Interfaces and dispatcher tools, running in parallel.
• Weeks 20 to 28, roughly 15 percent. Failover testing, shift by shift training and cutover.

Two schedule realities specific to a comm center. Training happens four times because you have four shifts and they will never be in a room together. And you cannot rehearse cutover during a busy period, so your go live date is negotiated against weather, holidays and your call volume curve rather than against the development schedule.

The costs nobody puts in the quote

Dispatch is the one public safety system where the running cost genuinely rivals the build, and it is because the building never closes.

• On call engineering, 20 to 30 percent of build cost a year. Not the 15 to 20 percent that applies to records or inspection systems. A dispatch dependency that fails at 2am on a Saturday needs somebody who can fix it at 2am on a Saturday, and that rota costs what it costs. On a $220,000 build, budget $44,000 to $66,000.
• Redundant hosting, $12,000 to $60,000 a year. Two of everything across separate failure domains, plus the backup center posture. A single region deployment is not a design your county attorney will enjoy explaining.
• Failover exercises, $6,000 to $15,000 a year. Untested failover is not failover. Somebody has to run the drill, fix what it exposes, and document it for your accreditation file.
• Interface maintenance, $10,000 to $30,000 a year. Your CAD vendor, records vendor and ePCR vendor all upgrade on their own schedule, and every upgrade is a retest. With six interfaces this becomes a standing quarterly task.
• Security recertification, $8,000 to $25,000 per cycle. Criminal justice information audits recur, and evidence collection is work whether or not anything has changed.
• Dispatcher training, $8,000 to $20,000 a year. Telecommunicator turnover is among the highest in public safety. You are not training once. You are training continuously, and the material has to be maintained by someone.

When not to build

Do not build a custom dispatch core because your current screen looks dated. A modern console on a product you can buy is the cheaper answer, and the difference funds two dispatcher positions.

Do not build if you cannot staff the system for the next decade. This is the single most common failure in custom CAD. The build goes well, the center is delighted, and four years later the two people who understood it have moved on and the county has no line item for the rota that keeps it alive. If your finance director will not commit to the annual support number above, buy a product and put your custom money into the layer around it.

A full custom core is justified in a narrow set of cases: a large consolidated or regional center, a deployment model that genuinely does not fit any product on the market, and an organisation with the budget and the staffing to own a life safety system for ten years. Everyone else is better served by keeping the core, buying your own data back out of it, and building the interfaces and dispatcher tools your vendor keeps putting at the back of the queue.
