The only proof this system works is a wholesale invoice that never arrives, so judge candidates on how they take events out of the call path and what graduated actions they wire back in. Expect $80,000 to $175,000 for real-time detection with automated blocking over 12 to 18 weeks. If your outbound international exposure is small, buy a destination whitelist and stop.
You will judge this build by something that does not happen. A customer's on-premise private branch exchange with a weak SIP password gets registered by someone else on Friday night, and by Monday there is nothing but a short list of blocked attempts in a queue. No invoice, no argument with your upstream carrier, no conversation about who absorbs a five figure loss for traffic that genuinely traversed the network and was genuinely paid for downstream.
That makes it hard to buy. Nothing in a demo separates a system that would have caught last quarter's international revenue share fraud from one drawing charts about traffic you already understood. Worse, you are hiring someone to write code that touches production signalling and then acts on it, handing a stranger the power to bar a customer's outbound line at three in the morning. Most agencies have never built anything that shape and will not volunteer it.
What a telecom fraud management development company actually does
The screens are a case queue and a dashboard, maybe a quarter of the work.
Events come off your softswitch, session border controller or class 4 platform out of band, so detection never sits inline with signalling and can never break calling. Rolling counters run per customer, per trunk, per destination prefix and per originating address, on windows measured in seconds rather than on call detail records arriving after mediation. Baselines are per customer, because a dental practice that has never dialled abroad and a freight forwarder calling Lagos daily cannot share a threshold. Then graduated action wired into your own controls: cap concurrent channels to a destination without dropping live calls, bar one prefix range for one customer, suspend international outbound while domestic and emergency calling stay up, deregister a compromised endpoint. Every tier reversible, scoped to one account, logged with the rule version and the evidence that fired it.
And a case object built properly on day one: the first anomalous event, each action with actor and timestamp, the rule set in force at that moment, every customer notification. That file is what you hand your upstream carrier when the argument over payment starts.
What it really costs in 2026
Bands from Digital Heroes delivery experience across 2,000+ projects, for an operator with one primary traffic source.
| Scope | Cost | Timeline |
|---|---|---|
| Shadow mode detection only, outbound international, one platform, alerting to a queue | $45,000 to $90,000 | 8 to 12 weeks |
| Real-time detection, per customer baselines, editable rule engine, graduated automated action, case queue with audit | $80,000 to $175,000 | 12 to 18 weeks |
| Multi source correlation, learned scoring, SIM swap and subscription fraud, reconciliation against wholesale invoices | $220,000 to $500,000 | 8 to 14 months |
| Rule tuning and new pattern response | 15% to 20% of build per year | Retainer |
Two costs get left out of almost every proposal.
The tuning window. A quote ends at handover, and the system defends nothing at handover, because rules must run in shadow mode against live traffic long enough to see a month end, a campaign ramp and a holiday weekend before anyone arms them. Four to eight weeks of an engineer's attention afterwards is the real number. A firm that has not priced it has quoted a delivery date, not a defence.
Your tenant hierarchy. Proposals say integration, singular. In a reseller structure the account you must suspend sits two or three levels below the account you bill, and the endpoint you must deregister belongs to a customer of a customer. Suspending at the wrong level either misses the fraud or takes out a partner's entire base. Model the hierarchy in discovery, before anyone estimates the action layer.
One detail that is not a cost and will cost you anyway: barring international outbound must never disturb emergency calling. Your suspension logic has to keep 911 or 112 routing intact for every tier, and that requirement belongs in the specification rather than in a code review comment in week ten.
Signals of a strong partner
- They refuse to sit inline with signalling. A competent telecom engineer says this before you ask, because fraud detection must never be able to break calling.
- They describe the international revenue share fraud signature precisely. The short test calls first, why concurrency matters more than call count, and why a destination being new to that customer is the strongest single feature.
- They propose graduated tiers, not a kill switch. A firm offering only suspend has not thought about the false positive that silences a hospital's outbound line.
- They want the rule engine in your hands. Your team should be able to write a rule on Saturday, run it in shadow against live traffic, and arm it when convinced.
- They push machine learning to phase two. With no labelled history of confirmed cases and confirmed false positives, a model is a random number with a confidence score.
- They ask about your upstream dispute window. Evidence only has value inside the period your wholesale contract allows for raising a traffic dispute.
- You own the rules from the first commit. Those rules are your accumulated knowledge of how you get attacked, and they are worth more than the code around them.
Red flags
- Detection built on post-mediation call detail records. That data arrives hours or a day late. It is fine for revenue assurance and it is an expensive way to read your own invoice early.
- Global thresholds with no per customer baseline. Support raises the limit for every complaining customer, and within a quarter the control has quietly stopped existing.
- Automated action with no reversal path. Every tier needs a documented undo and a named person who can execute it at three in the morning.
- No shadow mode. Arming untested rules against live traffic turns a fraud project into an outage.
- Vendor hosted rules. You cannot be filing a ticket to change a threshold while an attack is running.
Questions to ask on the first call
- How do you get call events out of our platform without touching the call path?
- Describe what the first ninety minutes of an international revenue share fraud attack looks like in your data.
- Which graduated actions would you build, and how is each one reversed?
- How does a suspension keep emergency calling available?
- In our reseller hierarchy, at which level does an automated action apply, and how do you avoid taking out a partner's whole base?
- How long does shadow mode run before anything is armed, and who tunes it?
- What do you do about a call centre that legitimately ramps concurrency for a campaign?
- How does the case file support a dispute with our upstream carrier, and what evidence does it hold?
- Who owns the rule set, the repository and the infrastructure accounts if we part ways?
A simple way to decide
Buy a paid discovery phase before a build. Three to five weeks, commonly $8,000 to $18,000, with one deliverable you own outright: a specification naming your event sources and their shapes, the baseline features, the action tiers with reversal paths, the tenant hierarchy, the shadow mode plan and a phased estimate. Send that same document to three firms. Until it exists, each prices a different imagined system and the cheapest is the one that imagined least.
Before that, run the cheap test. Send a candidate one week of call detail records and a description of your last incident, and ask which rule would have caught it and how early. A firm with real telecom experience answers in days with a specific feature. A generic anomaly detection shop answers with a methodology.
Digital Heroes is the wrong choice if your customers rarely call internationally. Set a destination whitelist, bar international by default with opt in, cap per customer credit, and spend nothing. We are also wrong for a large carrier with a staffed fraud function, where the depth in Subex or Mobileum earns its price. We fit hosted voice, wholesale and CPaaS operators in between, sitting between customers they do not control and carriers they owe. We work product requirement document first, you own the code and the rules from the first commit, and we contract through an India LLP, a US LLC or a UK LTD so intellectual property assigns under your own law. Checkable through D-U-N-S, Clutch and Trustpilot.

Frequently asked questions
What is the difference between a fraud management system and revenue assurance software?
Revenue assurance reconciles what happened on the network against what was billed, working from records after mediation, and it finds money you failed to charge for. Fraud management works on live traffic in seconds and stops money leaving. They share data sources and answer opposite questions. Buying a revenue assurance tool to prevent international revenue share fraud gives you an accurate account of a loss you already took.
How long before a new fraud system is actually blocking anything?
Detection can be live in twelve to eighteen weeks, but it will be watching rather than acting. Rules need to run in shadow mode against real traffic through a month end, a customer campaign and a holiday weekend before anyone arms them, which adds four to eight weeks. Any timeline that ends at handover has quoted a delivery date rather than a working defence.
Can automated blocking take down a paying customer by mistake?
It can, which is why the design uses graduated tiers rather than a single suspend. Capping concurrent channels to one destination, then barring one prefix range, then suspending international outbound while domestic and emergency calling continue, each scoped to a single account and each reversible, keeps the blast radius small. The alternative, alerting only, means your defence is whether somebody happens to be watching on a Saturday.
Who owns the detection rules if an agency writes them?
You should, explicitly, in the contract. The rules encode how your business gets attacked and they become more valuable than the code around them. Insist the rule set lives in your repository from the first commit, is exportable in a readable format, and carries no residual licence to the developer. A vendor holding your rules can charge you for your own accumulated experience.
Should we buy Subex or Mobileum instead of hiring a development company?
If you are a large carrier with a staffed fraud function, multiple networks and appetite for a multi quarter deployment, yes. Their domain depth is real and rebuilding it would be foolish. The mismatch appears at smaller scale, where tuning is a professional services engagement each time and you cannot change a rule at midnight during an attack. That iteration speed is usually the deciding factor.
Do we need machine learning for telecom fraud detection?
Not at the start, and starting there is backwards. You have no labelled history of confirmed fraud and confirmed false positives, so a model has nothing to learn from. Rules plus per customer behavioural baselines catch the catastrophic cases. Once a year of labelled case outcomes exists, scoring on top of the rules genuinely improves precision and shrinks the review queue. Sequence matters more than technique.
What happens if we are attacked while the system is still in shadow mode?
You handle it the way you do today, and the shadow system tells you whether it would have caught the attack and how early. That is exactly the value of the window. Keep existing controls, credit ceilings and destination barring in place throughout, and treat every incident during shadow mode as a free labelled example for tuning. Do not remove an old control until a new one has been armed and proven.
Can international calling be barred without affecting emergency calls?
Yes, and it must be. Emergency routing has to survive every suspension tier, including a full international bar and an endpoint deregistration. This belongs in the written specification as an explicit requirement with its own test case, not as something discovered in a code review. Ask any candidate how they test it, and expect a specific answer about their regression suite.
How much does rule tuning cost after launch?
Budget roughly fifteen to twenty percent of the build cost per year, or a small monthly retainer, and treat it as running cost rather than a defect. Attack patterns change faster than any release cycle, and a system whose rules stop being edited degrades within months. The cheaper alternative is training your own engineer to write and shadow test rules, which is a good reason to insist the rule engine is usable by your team.
Can we recover the money from the customer whose PBX was compromised?
Rarely in full. The calls genuinely traversed the network, your upstream carrier genuinely paid termination, and the premium revenue has already been shared across parties you cannot reach. You can pursue the customer whose equipment was breached, and they will point at your platform, and pursuing them usually costs the relationship without recovering the money. Prevention is the only reliable economics here.
What does a $50,000 custom software budget actually buy?
One core workflow done properly: 10 to 15 screens, two or three user roles, a couple of integrations, an admin panel, and automated tests, delivered in roughly 12 to 14 weeks. What it does not buy is that workflow plus a mobile app plus AI features plus five more integrations. The discipline of picking the one workflow that matters is what separates $50,000 projects that ship from $50,000 projects that stall at 70% complete.
What does it cost to keep custom software running after launch?
Budget 15-20% of the original build cost per year, which on a $100,000 system means $15,000 to $20,000 for security patches, dependency updates, bug fixes, and small improvements as real usage reveals what the spec missed. Cloud hosting for a typical business application adds $50 to $300 a month on top. Skipping maintenance does not save the money; in Digital Heroes rescue work, unmaintained systems typically need a far more expensive rebuild within about three years.
Our developer disappeared mid-project. Can another team pick up the code?
Yes, this is a routine engagement, provided the code exists somewhere you can access, so your first move is securing the repository, hosting, and domain credentials today. A takeover starts with a one to two week paid code audit that ends in one of three verdicts: continue the build, keep the design but rebuild the weak parts, or start over. Digital Heroes has inherited enough projects to say plainly that sometimes the rebuild is cheaper than the rescue, and an honest agency will tell you which one you have before taking your money.
How do we get years of data out of our old system and into the new one?
Treat migration as a planned sub-project: a field-mapping document, at least one dry run on a copy of your data, then a cutover with the old system kept read-only for 30 days as a safety net. On Digital Heroes projects it consumes 10 to 15% of the budget when the old system has an export, and more when data must be pulled out screen by screen. Ask any vendor to walk you through their last migration before you sign.
If an agency builds my software, who actually owns the code?
You should own everything, assigned in writing: the contract transfers full IP to you on final payment, the code lives in your GitHub organization, and hosting runs in cloud accounts you control. The red flag is a proposal that mentions the agency's proprietary platform or framework, which usually means you are renting, not buying. Digital Heroes structures every build this way precisely so a client can fire us and lose nothing but the relationship.
What should I have ready before I contact a development agency?
Three things, none of them technical: a one-page description of the problem in your own words, a list of the tools and spreadsheets the new system must replace or connect to, and a must-have versus nice-to-have split of features. Add a budget range, even a wide one, because it changes the conversation from fantasy to engineering. You do not need a formal specification; producing that is what a discovery phase is for.
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.

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.
