Shortlist three firms that have shipped media localisation tooling rather than generic workflow apps, and judge them on how they handle a picture change mid project. Expect $60,000 to $130,000 for a first release in 12 to 18 weeks, and $190,000 to $420,000 for a full platform with dubbing and delivery packaging. Below roughly one hundred language versions a year, keep OOONA and a good producer.
Commissioning subtitling and dubbing workflow software is like re-laying track under a train that does not stop. Your slate keeps arriving, linguists keep working, and the new system has to take over a running operation without dropping a delivery date. There is no quiet weekend in media localisation.
What makes this category awkward to buy is that the visible product is the part you should not build. A firm can show you a lovely editing surface and still have no idea what happens when a studio issues a new picture version in week six and thirty language tracks fall out of conform. The layer that decides whether you make money, meaning your quality control rules, your delivery profiles, your linguist pool and your dubbing schedule, has no demo. You are buying judgement you cannot see in a sales call.
What a media localisation development company actually does
The code that draws a subtitle on a timeline is perhaps a fifth of the engagement. The rest is modelling work that decides whether your operation gets faster or simply gets another login.
A firm worth hiring spends its first weeks on the object model. A title carries explicit versions, each with its frame rate and timecode start, and language tracks bind to a version rather than to the title. That one decision is what lets a new picture version light up every track that has gone stale, and show the stage each one sits at. After that comes the quality control engine, where reading speed in characters per second, characters per line, minimum duration, gap between events and shot change adherence become a profile per client instead of a habit in a reviewer's head.
Then delivery. Each platform specification is expressed as structured data, the package is generated from it, and the generated package is validated before it leaves the building. Underneath all of that sits media infrastructure: proxy transcoding, secure streaming to linguists in a dozen countries, storage, and whatever watermarking your studio clients require. That is engineering, and it is also a monthly bill that never stops.
What it really costs in 2026
These are the bands we quote and see quoted for custom localisation platforms. A firm landing far under them has priced a different brief than the one you sent.
| Scope | Cost | Timeline |
|---|---|---|
| Workflow core: title and version model, per language tracks, linguist pool with capacity and rates, automated quality control | $60,000 to $130,000 | 12 to 18 weeks |
| Full platform: conform automation, delivery profiles with package validation, dubbing casting and session scheduling, margin per title reporting | $190,000 to $420,000 | 7 to 12 months |
| Linguist portal and client facing status, multi language interface | $35,000 to $90,000 | 6 to 10 weeks |
| Support, defect cover and enhancements after launch | 15 to 20 percent of build cost a year | Retainer |
Two line items go missing from almost every quote in this category. The first is media running cost. Transcoding proxies, holding mezzanine files and streaming them to distributed linguists is operating expenditure that scales with your slate, and it does not appear on a build quote at all. Ask for a monthly figure at your current volume and at double it.
The second is delivery profile authoring and content security. Every platform you deliver to is a separate profile to write, test and maintain, and specifications get revised without asking you. Separately, studio clients increasingly expect a content security posture assessed against the Trusted Partner Network programme, and discovering that requirement after the architecture is chosen means re-engineering where assets live and how they stream. Confirm what your contracts already oblige you to do before anyone draws a diagram.
Signals of a strong partner
- They ask about frame rates before they ask about screens. Material authored against 23.976 and delivered against 25 without conversion reaches the viewer as a defect, and a firm that has shipped here raises it unprompted.
- They talk you out of building the editor. An editing surface professional linguists will accept is a multi year product effort. A partner who says so is protecting your budget rather than ducking work.
- Validation runs on the generated package. Checking source files proves little. Rejections come from naming, folder structure, encoding and audio track labelling in the thing you actually shipped.
- They treat a picture change as a fan out event. Listen for versioned sources, tracks bound to a version, change lists and targeted re-timing rather than a project marked as needing rework.
- They price media infrastructure as a running cost. Proxy generation, storage and egress recur monthly, and anyone who has operated one of these systems hands you a number instead of a shrug.
- They ask what your studio clients require of you contractually. Content security obligations decide where assets live. That belongs in week one, not in a security review three days before launch.
- Your repository and your cloud accounts from the first commit. Not a handover at the end. You should be able to hire somebody else on any Monday without a negotiation.
Red flags
- They lead with a better subtitle editor. It is the most demonstrable part of the domain and the least valuable thing you could commission. It signals they have not worked out where your margin comes from.
- A fixed price before they have read one delivery specification. The specification is the requirement. Quoting without it means the change orders are already written, just not by you yet.
- Version handling is a status field. If a new picture version sets a flag rather than invalidating bound tracks, your producers keep doing the fan out by email and you have paid for a dashboard.
- Media appears in their architecture as a file upload. No proxy strategy, no streaming plan, no storage lifecycle. That gap surfaces the first week a linguist in another country cannot play the video.
- They want to hold your assets in their own cloud account. That is a dependency dressed as convenience, and with studio material under contract it can also be a breach of your own obligations.
Questions to ask on the first call
- Show me how you would represent one title with three picture versions and eighteen language tracks sitting at different stages.
- Which of our quality checks would you automate outright, and which would you deliberately leave to a human reviewer?
- How would you express a platform delivery specification so a package can be generated from it and then validated against it?
- What happens to a dubbing session already recorded against the previous picture, and how does the system surface that?
- Where does 23.976 to 25 conversion logic live, and how do you test it?
- Whose account holds our mezzanine files and proxies, and what is the monthly infrastructure cost at our current volume?
- How do linguists get playback without us handing them a master file?
- What do you need from our existing subtitle editor, and how do we keep using it after go live?
- What exactly do we own on the last day, and what happens if we hire a different firm in month nine?
A simple way to decide
Do not pick from proposals. Buy a paid discovery phase from your top two firms and run them either in sequence or side by side. Two to four weeks at a defined fee should leave you owning a written specification: the title and version model, the quality control rule set, one delivery profile expressed in full, a media architecture with a monthly running cost attached, and a build plan priced by phase. That document belongs to you. You can hand it to any other firm on your list, or to none of them.
If discovery does not produce something you could hand over, the firm sold you a start date rather than a plan. Digital Heroes works this way by default, writes a product requirements document before any code, and contracts through an India LLP, a US LLC or a UK LTD so the intellectual property assigns under your own law. We are the wrong choice if you deliver under a hundred language versions a year: stay on OOONA, hire a stronger producer, and spend the difference on linguists.

Frequently asked questions
How long does it take to build a media localisation workflow platform?
A first release covering the title and version model, per language tracks, the linguist pool and an automated quality control engine ships in roughly 12 to 18 weeks. A full platform with conform automation, delivery packaging, dubbing casting and scheduling runs 7 to 12 months. Media infrastructure decisions usually set the pace, because proxy generation, secure streaming and storage have to be settled before much else can be built.
Who owns the code and the media assets when an agency builds this?
You should own the repository, the cloud accounts holding your proxies and masters, and the unrestricted right to hire another firm to continue. Settle it in writing before kickoff rather than at handover. It matters more here than in most categories, because studio contracts often place obligations on you about where content is stored and who can reach it, and you cannot honour those from someone else's account.
What happens if the studio delivers a new picture version halfway through a project?
In a well built system, every language track is bound to a specific source version, so a new version immediately shows which tracks are stale and at what stage. Where a change list is supplied, timing offsets apply automatically after each edit point and only affected regions go for human review. Dubbing sessions recorded against the old picture need their own review path, because audio cannot be nudged the way a subtitle can.
Can we keep using OOONA and still have custom workflow software?
Yes, and that is usually the right shape. Keep the editing surface your linguists already know and build the operational layer around it: assignment, capacity, quality control rules, delivery profiles, dubbing scheduling and margin reporting. The integration work is a redirect or an export and import path rather than a rewrite. Replacing a mature editor is a multi year effort with no commercial payoff.
Should we outsource this offshore or hire an in house engineering team?
Hire in house only if localisation tooling is a product you intend to sell, since keeping two or three engineers busy on internal tooling year round is difficult to justify. For most vendors an outside firm builds the platform against a written specification, then a single technical owner inside your operation handles change requests and holds the roadmap. Insist on documentation and code ownership so that swap is possible.
What is the difference between a subtitling tool and a localisation workflow platform?
A subtitling tool edits one file: timings, text, line breaks, styling. A workflow platform runs the business around thousands of those files. It knows which linguist has capacity, which track belongs to which picture version, whether a file passes the client style profile, how the package should be assembled for a given platform, and what the title cost you by language. The tool is the pen. The platform is the operation.
How much does dubbing add on top of a subtitling scope?
Expect dubbing casting and session scheduling to add roughly 40 to 60 percent to a subtitling only workflow build. The reason is that dubbing introduces physical constraints subtitling does not have: a studio room, an engineer, a director, and voice talent with agents and availability. Voice continuity across seasons has to be modelled too, and music and effects stem availability becomes a tracked dependency rather than an assumption.
Can the system stop a delivery that would fail a platform technical check?
It should, and that is the single feature most worth paying for. Mechanical checks such as reading speed, characters per line, event gaps, encoding, naming and audio track labelling can all be run against the generated package before it leaves. A track or package that fails does not advance. Human reviewers then spend their attention on meaning and register instead of counting characters at eleven at night.
What does it cost to run the media infrastructure every month?
It depends on slate volume and how you stream to linguists, but treat it as a real recurring line rather than a rounding error. Proxy transcoding, mezzanine storage, and egress to reviewers in many countries all bill monthly and grow with your business. Ask any prospective firm for a figure at your current volume and at twice that volume, and make them show the assumptions behind it.
What happens to titles already in flight when we cut over to a new system?
Run both processes in parallel for at least one delivery cycle. New titles start in the new system, in flight titles finish where they began, and only the linguist pool and rate data are migrated up front. Trying to import half finished tracks with their partial review state is where these projects lose weeks. Plan the cutover around a quieter point in your slate rather than a calendar date.
How much should a small business budget for its first custom app or website?
For a focused first build, most small businesses land between $8,000 and $60,000: roughly $8,000 to $45,000 for a custom website and $25,000 to $60,000 for an internal tool or simple web app, based on Digital Heroes delivery across 2,000+ projects. Customer-facing products with payments, logins, or a mobile app start around $40,000. Quotes far below these bands usually mean a template with your logo on it, not software shaped around your workflow.
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 much does it cost to build a custom project management tool for my company?
A focused build that replaces one painful workflow runs $60,000 to $90,000, and a full platform with portfolio views, client access, and integrations runs $120,000 to $200,000 or more. Those are Digital Heroes delivery bands across 2,000+ projects, not list prices. Add 15 to 20 percent of the build cost per year for hosting, maintenance, and integration upkeep.
Who owns the code when an agency builds my project management software?
You should, in full, and the contract must say so: work-for-hire language with all intellectual property assigned to you on final payment. Watch for agencies that license you their platform or framework, because that quietly turns your custom tool back into a subscription you cannot leave. Digital Heroes assigns full ownership and delivers into a GitHub organization the client controls; treat anything less as a red flag.
How big a team does it take to build a project management platform?
A typical Digital Heroes pod is 4 to 5 people: a product designer, two or three engineers, and a shared project manager and QA. Smaller than that and timelines stretch because one person is context-switching across design, backend, and testing; bigger only helps after the MVP, when work splits into parallel streams. Headcount matters less than whether the same pod stays on your project from discovery to launch.
How small can the first version of my software be and still be worth building?
One workflow, end to end, for one type of user: the single process that currently burns the most hours or loses the most money. In Digital Heroes delivery experience, first versions scoped to 6 to 10 weeks of build time ship, get used, and generate the feedback that makes version two obviously right, while 9-month first versions routinely launch with features nobody touches. Everything you cut from v1 gets cheaper to build later, because real usage reorders the roadmap for you.
How long does it take to build custom project management software?
Plan on 12 to 16 weeks for a working first version and 6 to 9 months for a mature platform; those are typical Digital Heroes delivery timelines. The schedule killers are undecided permission rules and mid-build scope additions, not the code itself. Locking the workflow map during discovery is what keeps a build inside 16 weeks.
Which integrations should a custom project management tool have?
Start with the three that move money and attention: Slack or Teams for notifications, calendar sync for deadlines, and your accounting tool such as QuickBooks or Xero so tracked time flows into invoices without retyping. Development teams usually add GitHub or GitLab so tasks close when code merges. Each solid two-way integration adds roughly 1 to 2 weeks of build time, so rank them by hours saved per week rather than wishlist order.
Who can build a custom project management software system?
Digital Heroes builds custom project management 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 project management 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.
