# App Development Company > A fixed scope, a fixed price and a delivery date agreed before anyone writes code. Web and mobile apps shipped by an AI Pod, in market since 2007. Source: https://www.koombea.com/app-development-company/ --- Koombea builds web and mobile apps as AI Pods. We break the scope into story points and price it before work starts, so the number you approve is the number you pay. ## Why app budgets move Around 70% of software projects go over budget or miss their deadline. The reason is rarely bad engineering. It is that the number was a guess, made before anyone had read the requirements closely enough to cost them. An hourly quote hides that. It prices effort, so every discovery becomes your cost. Scope grows, the invoice grows with it, and the change order arrives after you have already committed. We price the scope instead. We break requirements into story points first, sizing each one on functional surface area, integration count and the test coverage needed to ship it. That is slower to start and it is the reason the number holds. - The estimate comes before the commitment, not after it - ScopeGen AI puts estimate accuracy near 95%, and cuts overruns by up to 60% - We reprice a change in points, so you see the cost before you approve it - On Time and On Budget, because the budget came out of the scope ## An hourly quote, or a committed scope | | Hourly and time-and-materials | An AI Pod | |---|---|---| | What you are buying | Effort. You pay for the time spent, whatever it produces. | Delivered scope. You pay for the features you agreed to, at a price set in advance. | | When the price is set | Provisionally at the start, then again at every change order. | Before work begins, from a scope broken into story points. | | Who carries the estimate risk | You do. An underestimate becomes more hours on your invoice. | We do. An underestimate is our problem, which is why we scope properly first. | | What a change costs | Unknown until it is built, then billed at full rate. | We reprice it in points and quote it before you approve it. | | How progress is read | Hours logged, which says nothing about what works. | Points accepted every two weeks, against software you can use. | | What you manage | A team, its capacity and its calendar. | A backlog. The Pod runs itself and reports on delivered scope. | ## From idea to a number in days Scoping is free and it is real work, not a sales call. You leave it with a document you could hand to another firm. You describe the app: What it has to do, who uses it, and what it has to connect to. If code already exists, point us at the repository. Nothing here needs a specification you have not written yet. (One call, 30 minutes) We read it properly: Requirements go through ScopeGen AI and then through the people who would deliver them. Existing code gets a review, because estimating work on a codebase nobody has read is a guess with a decimal point on it. (Discovery and code review) You get the scope and the price: A Work Breakdown Structure written as user stories, sized in story points, with the price and the delivery date attached. You also get an honest answer on whether Staff Augmentation suits you better. (Scope Alignment, in writing) A Pod ships it: Working software every two weeks, against the scope you approved. You have repository access throughout, and source and pipeline transfer is a gate on Phase 1 acceptance rather than a favor at the end. (Two-week cycles) ## Where this fits Four situations account for most of what arrives. Each one changes what Phase 1 has to prove, so it changes what gets built first. - **A first product**: Phase 1 is a complete end-to-end loop a real user can finish, not a login screen and a design system. A loop can be tested, demoed and funded. - **An enterprise platform**: Multi-tenant isolation, single sign-on and audit trails built as you go. Reconstructing them after a compliance review costs more than building them. - **Planning and scoping**: You have a budget to defend and no costed plan. Scoping produces the Work Breakdown Structure and the number, and it stands on its own. - **A rescue**: A build that stalled with another partner. Discovery says plainly whether a rescue or a rewrite is cheaper, before either of us commits to one. ## What we build Native iOS and Android where the experience is the product, cross platform where the requirement genuinely allows it. We settle that fork on evidence during scoping, because a team that picks cross platform for the saving and then specifies a native-feeling app pays for both. Design, engineering, quality and infrastructure all sit inside the Pod and inside the price. There is no separate line item for the parts an app needs in order to ship, and no handoff between firms where the estimate quietly resets. - Mobile apps for iOS and Android, native or cross platform - Web applications, APIs and the infrastructure to run them - eCommerce, including Shopify Plus replatforms and native storefronts - Product design and UX, priced in the same points as the build - Quality engineering and test automation, so acceptance is measurable - Cloud infrastructure and release pipelines, on AWS ## Apps we shipped Apps built here have been acquired by Google, Motorola Solutions, Facebook and Skype. "The Payix team is very thankful to Koombea for stepping in and helping us move past our previous development partner. With Koombea now by our side, we're achieving our client onboarding goals and maximizing revenue opportunities." Chris Chestnut, CEO, Payix ## Brands that shipped with us ## Partnerships and certifications Third-party appraisal rather than self-assessment. CMMI-DEV/3 appraised, AWS Partner, Shopify Plus Partner. ## Request a free consultation Describe the app and we will come back with the scope, the price and the date. Our working day sits inside the US Eastern business day all year, so the hours you keep are the hours we keep. Ask and you get an NDA before you tell us anything. ## What buyers ask first ### How much does an app cost? It depends on scope, and a published figure would be wrong for most projects. What we will do is show you exactly what moves the number during scoping. Distinct states per screen matter far more than screen count, one more system to reconcile against costs more than several more list views, and four permission levels make a different app from the same features with one. ### Is the price really fixed? Yes, for the scope you approved. We break scope into story points and price it before work starts, and the people who have to deliver the work build the estimate. We reprice new scope in points and quote it before you approve it, so a change is a decision you make rather than an invoice you receive. ### How long does it take? Delivery runs in two-week cycles, and the date comes out of the point count rather than out of optimism. You get it with the price, before committing. What most often moves it is content and approvals on your side, and we will say so during scoping if that looks like the risk. ### Can you take over an app another firm started? Often, and this is a large share of what we do. Discovery starts with a code review, because the honest answer is sometimes that a rewrite is cheaper than a rescue. You get that answer before either of us commits to anything. ### Who owns the code? You do, throughout. Repository access is yours from the start, and formal transfer of source and pipeline access is a gate on Phase 1 acceptance rather than something negotiated at the end. ### Native, cross platform, or web? The requirement decides and we show the reasoning. Cross platform is right when the app is forms, lists, content and standard navigation on both platforms. Native wins when the experience is the product, or when you depend on hardware and OS features that move quickly. ### What if we just need extra engineering capacity? Then say so and we will quote Staff Augmentation instead, hourly, with your team directing the work. It is the other model we sell, and it is the right one when you own the backlog and only need capacity. AI Pods suit you when you want committed scope at a known price. ### What does AI-First actually change? AI runs across the whole lifecycle here, from scoping through test generation, which is what makes the throughput per dollar work. ScopeGen AI is why estimates land near 95% accuracy. Tambora is why test coverage arrives with the feature instead of after it.
