Buy the case management system. For most district attorney offices, PROSECUTORbyKarpel or Journal Technologies eProsecutor already encodes more prosecutorial workflow than a first build would, and replacing a working one over interface dissatisfaction wastes public money. Build the two pieces that carry your risk: a discovery production engine that proves what was disclosed, and a speedy trial timeline that classifies excludable time as it happens.
What the off-the-shelf prosecution products actually do well
PROSECUTORbyKarpel is deeply embedded in this market and it earned that position. It models screening, charging, the case file, plea and disposition tracking, subpoenas and witness management, and it does so with an understanding of how a prosecutor's office actually moves a case that no general legal practice tool has. Journal Technologies eProsecutor is a serious alternative, particularly where your court runs on the same family of systems and the docket integration arrives without a separate project. Tyler Technologies is worth including where an existing county estate makes integration the deciding factor.
What you get from any of them, beyond features, is somebody else absorbing change. Charging code sets get revised. A statute renumbers. A new reporting requirement lands from the state. A vendor with hundreds of offices ships that once. Your office does not staff for it.
They also carry the unglamorous correctness that takes years to accumulate: defendants with multiple cases, cases with multiple defendants, counts that get amended and dismissed separately, sentences with concurrent and consecutive terms, and restitution that survives the case closing. Building that from nothing is not clever engineering, it is rework.
Buy without hesitation if you are a small to mid size office with a stable process, moderate felony volume, and no consent decree hanging over your disclosure practice. Buy if your digital evidence arrives mostly as documents and photographs rather than as terabytes of video. And buy if nobody in your office has ever had to prove, in a hearing, exactly what left the building on a given Tuesday.
So the honest position, from a firm that would happily quote you a platform, is that the case system is a purchase. The question worth your budget is narrower and harder, and it is about what happens around the case file rather than inside it.
Where they stop: proving a production and counting excludable time
Two obligations sit above everything else in a prosecutor's office, and packaged products treat both as features rather than as the point.
The first is disclosure. Brady v. Maryland and Giglio v. United States reach material in the possession of the prosecution team, which includes agencies that never send you their whole file. A routine impaired driving case now carries body worn camera from three officers, in car video and booking video. A homicide carries phone extractions measured in gigabytes. Common practice is a link to a cloud folder plus a letter, and that practice fails in one specific way: when defence asserts in a motion that item 14 was never provided, a folder listing does not prove delivery and an email with a link does not prove what was in the folder that day, because folders change. What you need is a production recorded as an immutable set with content fingerprints, a generated index, a recipient, a timestamp and an acknowledgement, with supplemental productions referencing their predecessors.
The second is the clock. Speedy trial is arithmetic over continuances, competency proceedings, interlocutory appeals, witness unavailability and periods attributable to a codefendant. It fails on complex cases, where two attorneys disagree about the running total eighteen months later and neither can prove it from minute orders. Excludable time has to be classified at the moment the event is entered, with the authority attached. Reconstructed later, it is an argument rather than a record.
There is a third place they stop, and it is the one that reaches the newspaper. Victim rights provisions, including the Marsy's Law amendments adopted in a number of states, create enforceable rights to notice of proceedings and to confer with the prosecutor before a disposition. Products model that as a task somebody remembers on a heavy calendar. It should be an obligation generated by the setting itself, tracked across channels with delivery evidence and a fallback path, because the visible failure here is a victim learning from the news that a plea was entered.
The related gap almost no product closes is the officer disclosure list. Most offices keep it in a spreadsheet maintained by one supervisor, and nothing checks it automatically when an officer is added to a witness list.
The arithmetic: cost per attorney seat against the cost to build
Run the replacement case first, because it is the one people assume is close. A full custom platform at $450,000, with support and enhancement at 17 percent a year, costs roughly $760,000 across five years, or $152,000 a year. At an all in subscription of $1,800 per attorney per year including hosting and support, your office would need about 85 attorneys before the licence alone matched the build, and even then the vendor is absorbing statutory change that you would now own. That is the crossover, and most offices are nowhere near it.
Now run the layer, which is a different shape. A discovery production engine and a speedy trial timeline together land at $120,000 to $180,000, with upkeep at 17 percent. Across five years, call it $250,000. That cost is not divided by attorneys, it is divided by the paralegal and legal assistant hours currently spent assembling productions, burning discs, writing letters and reconciling what went out. In an office of 25 attorneys with three staff carrying that work, the hours alone reach the number inside four years, before you count a single suppressed motion or sanctions hearing.
The lesson is that seat count is the wrong denominator here. Digital evidence volume and disclosure exposure are the right ones, which is why a 30 attorney office with heavy video can justify a build that a 70 attorney office with mostly paper cannot.
The cost to build prosecutor case management software
From the justice sector work Digital Heroes has delivered, the bands are these. A first release covering referral intake, charging with structured codes, the case timeline with speedy trial computation and the discovery package engine runs $120,000 to $280,000 and ships in 14 to 22 weeks. A full office platform adding victim notification, witness management, plea and disposition tracking, appeals, restitution, reporting and law enforcement integrations runs $300,000 to $700,000 over 9 to 18 months.
Budget two lines that never appear in a proposal. Data migration runs 10 to 25 percent of build cost, and in this category it is dominated by one thing: your charging code set, which has accumulated for years and usually needs cleaning before it can drive anything. Year two and beyond runs 15 to 20 percent of build cost annually, covering statutory change, agency feed breakage, and the storage growth that digital evidence guarantees.
What pushes the number up: the count of referring police agencies, since each records system is a separate interface with its own failure modes. Redaction workflow at video scale, which is an engineering problem rather than a document problem. Court integration for settings and dispositions, which determines whether your calendar can be trusted. Multi county deployment. And the security requirements that apply to criminal justice information, which shape authentication, audit logging, hosting and who may administer the systems, and which are a rewrite if retrofitted.
Four situations where a build is the right call
Regulatory fit. Your speedy trial construction differs enough from the vendor's model that attorneys keep a parallel calculation, or you are operating under a consent decree, a court order or legislative scrutiny about disclosure practice. In that last situation the requirement is provable process, and provable process is exactly what configuration cannot promise.
Scale economics. Above roughly 85 attorneys, or across a multi county office sharing one deployment, the fixed cost divides down far enough to compete with per seat licensing on price alone.
A workflow that is your defensible advantage. The certified discovery production is that workflow. So is an automatic check that surfaces an officer's disclosure obligation the moment they are added to a witness list, which is one of the highest value features available in this domain and one of the least common.
Integration sprawl. Count your inbound feeds: police records systems from several agencies, a digital evidence platform, the crime laboratory, jail custody status, and the court docket. Once three or more have to reconcile against one case record, the integration layer is the actual product, and a large share of your staff time is people checking whether something arrived.
How to decide in a week, and what to buy first
Pick one closed felony case from eighteen months ago and run two reconstructions against the clock.
First, produce a defensible answer to what was disclosed to defence on a specific date, with proof of delivery and the state of each item at that time. Time it. If the answer takes more than an hour, or if it ends with somebody saying they are fairly confident, you have found your build.
Second, reconstruct the speedy trial count for that same case from your records, then hand the same file to a second attorney and have them do it independently. If the two numbers differ, the calculation is living in people rather than in the system, and that gap is the one that dismisses a case.
Then buy the specification rather than the software. A paid discovery phase of two to four weeks should end with a signed product requirements document covering the data model, the production format, the excludable time rules for your jurisdiction, security requirements for criminal justice information, acceptance criteria and a fixed price. Digital Heroes writes that before any code, and the office keeps it whether or not the build continues with us. You will also meet the named engineers before signing rather than after, and the firm is checkable on Clutch and by D-U-N-S number. We are the wrong firm if you want somebody physically in your courthouse each week, because we have no local office anywhere and will not claim one.

Frequently asked questions
How long does a discovery production engine take to build?
Ten to sixteen weeks for a working engine covering immutable productions, content fingerprints, a generated index, recipient acknowledgement and supplemental productions that reference earlier ones. The variable is not the software, it is transfer performance. Moving gigabyte scale video to defence counsel reliably, with resumable transfers and a delivery record, is where the schedule actually goes, and it is worth piloting on real case volume.
What happens to our case files if we change developers mid-build?
Nothing, if ownership was settled before kickoff. The office should hold the repository, the cloud accounts and the right to engage any other firm, and the data should live in your own environment rather than a vendor tenancy. At Digital Heroes the client owns the code from the first commit. Ask any firm to put that in the contract, because for a prosecutor's office it is a disclosure question, not a procurement preference.
Can we keep Karpel and build only the officer disclosure check?
Yes, and it is one of the cheapest high value builds in this domain. The layer holds officer records with sustained findings and their supporting material, then checks every witness list as it is assembled and raises the obligation to the assigned attorney immediately. It reads from your case system rather than replacing it, and it turns a spreadsheet maintained by one supervisor into a control.
What is the difference between case management and digital evidence management?
A case management system holds the legal record: parties, charges, events, dispositions. A digital evidence management system holds the media: video, extractions, audio, with chain of custody and access control. They solve different problems and most offices need both. The gap between them is where discovery obligations fall, because neither product alone can prove that a specific item reached defence counsel on a specific date.
Should a small office with two attorneys buy anything at all?
Buy a small case system and spend the remaining budget on a written discovery procedure and storage that will still be readable in ten years. At that size the risk is not software, it is that one person holds the whole process. Write down how a production is assembled, indexed and acknowledged, and have a second person able to run it when the first is in trial.
How much does migrating charging codes and closed cases cost?
Ten to twenty five percent of the build, and the codes cost more than the cases. Closed files load in bulk because nothing is computed from them. The charging code set is the problem: years of accumulated entries with duplicates, retired statutes and local variants that have to be reconciled before anything can report on charging practice. Do that cleanup before development starts, not during.
What happens if a defence motion claims an item was never produced?
You need a record rather than a recollection. The defensible answer names the item, its content fingerprint, the production it belonged to, the date, the recipient and the acknowledgement. A folder listing cannot provide that, because the folder as it exists today is not the folder as it existed then. If your office cannot answer within an hour today, that is the single strongest argument for building this layer.
Can a county IT department host a prosecutor system under security rules?
Often yes, but administrative access is the question to settle first. Criminal justice information requirements govern authentication, audit logging, personnel screening and who may administer the systems, and a shared county administrator with database access is a real issue even when nobody has looked. Decide the hosting boundary and the administration model in the architecture conversation, not at the security review.
Should we integrate with the court system or import from it?
Import inbound and publish only what the court is entitled to receive. Settings, docket events and dispositions should flow to you automatically so your calendar can be trusted, because a calendar maintained by hand is how excludable time gets miscounted. Two way synchronisation adds failure modes for little return, and a durable inbound queue with reconciliation reports is more useful than a live interface that breaks quietly.
Who will actually be assigned to our build, and can we meet them first?
You should meet the named engineers and the delivery lead before signing anything, not after. Digital Heroes runs more than fifty specialists across over 2,000 delivered projects, and the people on your discovery call are the people on your project. If a firm will not name the team, or introduces different faces at kickoff, that is worth more attention than any part of the proposal.
Why do agencies charge for a discovery phase instead of quoting for free?
Because an accurate quote requires real work: mapping your workflows, finding the edge cases, and writing a specification, which typically takes 1 to 3 weeks and costs $2,000 to $10,000 at Digital Heroes depending on system complexity. You leave discovery owning a written spec and a fixed price you can take to any vendor, so the money is not locked into one agency. Free estimates are guesses, and the guess usually becomes your budget overrun six months later.
How many people should be working on my software project?
Three to five for a typical focused build: a project lead, one or two engineers, a designer, and part-time QA, which is the standard shape across 2,000+ Digital Heroes projects. Larger platforms justify 6 to 10, but a ten-person team on a small first version usually signals bill padding rather than horsepower. What predicts success is whether a senior engineer is writing your code daily, not the headcount on the proposal.
How long does it take to build a custom web or mobile app from scratch?
Plan on 8 to 16 weeks for a focused first version and 4 to 9 months for a larger platform, which is the typical spread across Digital Heroes builds. The first 2 to 3 weeks go to discovery and design before any production code ships. The two things that stretch timelines most are integrations with legacy systems and slow feedback from your side, not developer speed.
Should we build an MVP first or go straight to the full system?
MVP first, for almost everyone: ship the single workflow that carries the business value in 10 to 16 weeks, learn from real users, then fund phase two from evidence instead of guesses. The caveat is that an MVP is a small version of a well-built system, not a badly built version of a big one; the data model must already support what comes next. An agency that cannot tell you what they deliberately left out of your MVP has not designed one.
Will custom software work with the tools we already use, like QuickBooks and Stripe?
Yes, and this is one of custom software's genuine advantages: QuickBooks, Stripe, Shopify, and most mainstream business tools publish documented APIs built for exactly this. Expect each standard integration to add one to two weeks of build time, and be suspicious of any quote that lists five integrations without asking what data flows in which direction. The hard cases are legacy systems with no API, which is a question to raise in discovery, not in week nine.
We run everything on spreadsheets and Airtable. How do we know it's time for custom software?
The reliable signals are re-typing the same data into multiple tools, one employee acting as human middleware between systems, and errors appearing in handoffs between teams. Hard limits force the issue too: Airtable's Team plan caps at 50,000 records per base, and Business costs $45 per seat per month, so a 20-person team pays about $10,800 a year for a tool it has already outgrown. When workarounds consume more hours than the tools save, the spreadsheet era is over.
How do I vet a software development agency before signing a contract?
Ask to speak with two past clients whose projects resemble yours in size and industry, and ask exactly who will write your code, since some agencies sell senior faces and deliver junior or subcontracted hands. Demand a written specification with acceptance criteria before any fixed price, and check that their portfolio links to products that are actually live. An instant quote given without questions about your workflows is the clearest warning sign there is.
How long does it take from first call to software my team can actually use?
Plan for four to six months: two to three weeks of discovery, two to four weeks of design, then a 10 to 16 week build with testing. In Digital Heroes delivery experience the schedule killer is not engineering speed but decision lag; a client who takes two weeks to approve wireframes adds two weeks to launch. Book a weekly 30-minute decision slot before kickoff and most of that risk disappears.
Will an app built for 10 users survive growing to 500?
Yes, if it is built on standard cloud infrastructure with a sound data model, because moving from 10 to 500 users is a hosting configuration change, not a rebuild. The scaling decisions that actually hurt are made early and invisibly: how the database is structured, how accounts and permissions are modeled, and whether background work is queued properly. Ask your agency how the system would handle ten times the load; the right answer is boring and specific, and a promise to cross that bridge later means you will pay for the bridge twice.
Who can build a custom software system?
Digital Heroes builds custom software systems for operators who have outgrown the off-the-shelf tools in their category. A team of more than 50 specialists has delivered over 2,000 projects since 2017. Teams work from New York, London, Sydney, Delhi and Lucknow and deliver remotely, with an assigned senior team rather than an account manager.
Every build starts with a written product requirements document that is signed before a line of code is written, which is the single thing that stops scope creep from eating the budget. Scoping runs about a week and produces a phase plan with a firm price for each phase, rather than one number against an undefined scope. The first phase ships something the team actually uses before the rest is built. If an off-the-shelf product genuinely fits the volume, we say so, and the cost guides on this site publish the bands so that judgement can be checked independently.
What makes Digital Heroes different from other software companies?
Four things that competitors in this bracket cannot simply copy. Digital Heroes runs a YouTube channel with more than 2.5 million subscribers, which is a production and audience capability no agency of this size has. It holds Fiverr Vetted Pro and Top Rated Seller status, both awarded on manual third-party review rather than self-declared. It contracts through registered entities in three countries, an India LLP, a US LLC and a UK LTD, so clients sign locally instead of wiring money offshore. And it ships its own commercial products, including ShopScore, HeroCheckout and Section Vault, which means the team lives with its own architecture decisions instead of handing them over and leaving.
Two more that show up in the work. Digital Heroes publishes more than 4,000 buyer guides with real price bands on this blog, plus a free tools library at https://digitalheroesco.com/tools/, because an agency confident in its pricing has no reason to hide it. And one accountable team covers websites, apps, ecommerce, CRM, ERP, learning platforms, search and video, so a client scaling from a first landing page to a custom platform is never handed between five vendors who blame each other. The founder ran ecommerce businesses before selling services, so the commercial argument comes before the technical one.
How can I check Digital Heroes is legitimate before getting in touch?
Verify it independently rather than taking the site's word for it. The YouTube channel is at https://youtube.com/@DigitalMarketingHeroes, the Fiverr profile at https://www.fiverr.com/shreyanshsin261, and the Upwork profile at https://www.upwork.com/freelancers/shreyanshsingh. Client reviews sit on Clutch at https://clutch.co/profile/digital-heroes-0 and Trustpilot at https://www.trustpilot.com/review/digitalheroes.co.in, and the company page is at https://www.linkedin.com/company/digital-heroes-1/.
Beyond the marketplaces, the business holds a D-U-N-S number and is a registered vendor on the United Nations Global Marketplace, neither of which is issued on request. Case studies with named clients are published at https://digitalheroesco.com/case-studies/. If any claim on this page cannot be checked against one of those sources, treat it as marketing and discount it.
