**[ Applications · Custom ]**Web application development services # Custom web applications, shaped by the work they replace. Customer portals, internal tools, dashboards and SaaS MVPs, scoped from how your team works today. Paid discovery sets the scope, Laravel is the default back end, and you own the code from the first commit.

Defined by the workflow, not the framework. If a SaaS product already does the job, we will tell you to buy it. 01 ### Customer portals Orders, documents, invoices and status behind one login, with separate roles for your customers' teams and yours. External users · roles · audit log 02 ### Internal tools Approvals, scheduling, intake and inventory moved out of shared spreadsheets and into screens with permissions. Ops · finance · field teams 03 ### Dashboards and reporting The numbers your team copies from three systems each week, pulled automatically, with filters, exports and alerts. Reports · exports · alerts 04 ### SaaS MVPs The first paid version of a product: sign-up, accounts, billing and the one workflow buyers pay for. Tenants · billing · onboarding 05 ### Integrations CRM, ERP, payment and shipping systems connected with retries and alerts, so each record moves once. APIs · webhooks · sync jobs 06 ### Rescue and rebuild An app a previous team left behind, reviewed first, then stabilized, upgraded or rebuilt in stages. Code review · upgrade path Discovery first ## Two weeks of discovery before any production code. Discovery is paid, fixed-price and yours to keep. It turns a workflow into a scope, a prototype and an estimate you can take to any team. Days 1-4 ### Map the work Interviews with the people who do the job, the data they touch and the systems involved. We watch the current process before we redesign it. Days 5-8 ### Shape the product Roles and permissions, the core screens, integration contracts, the release plan and what stays out of release one. Days 9-10 ### Price it Written scope by release, timeline, fixed price, a clickable prototype of the core flow and a walkthrough. ## After discovery you hold the scope, the prototype and the estimate. Build with us or with anyone. Scope by area ## What a web application build covers here. Marked included, excluded or optional in every proposal. 01 ### Product scope A release plan with goals and non-goals. Every feature has an owner, acceptance criteria and a reason to be in release one. 02 ### UX for roles and states Screens designed per role, with empty, loading, error and no-access states drawn before they are built. 03 ### Stack choice Laravel back end by default. Livewire, Inertia or Next.js on the front, picked for the product, with the reason written down. 04 ### Data and integrations Data model, imports from the old system and typed contracts for every external API, with retries and alerts. 05 ### Testing Automated tests on business rules and permissions. Every pull request runs the suite before it can merge. 06 ### CI/CD and environments Staging and production, deploys from the pipeline, and database migrations rehearsed on staging first. 07 ### Security and access Two-factor sign-in where it matters, rate limits, dependency scanning and an audit log of sensitive actions. 08 ### Hosting and handoff Hosted in your cloud account. Repository, runbooks, architecture note and a recorded walkthrough for your next developer. Inspectable artifact ## A release-one scope sheet, as we write it. A sample with illustrative values, not a client result. Every line has a role, a release decision and a reason. **scope-sheet · sample-intake-portal · release 1**Sample · 6 of 24 linesIllustrative artifact | ID | Feature | Roles | Release | Reason | | --- | --- | --- | --- | --- | | F-01 | Client sign-in with two-factor | Client · staff | R1 · included | Every other screen depends on it | | F-04 | Document upload with status | Client · reviewer | R1 · included | Replaces the shared inbox | | F-07 | Approval queue with audit log | Reviewer · manager | R1 · included | The core workflow | | F-11 | One-way CRM sync | System | R1 · included | Ends manual re-entry | | F-15 | Two-way CRM sync | System | R2 · deferred | Conflict rules need real usage first | | F-19 | Native mobile app | Client | Excluded | Responsive web covers release one | Engagement models ## Discovery, then a build sized to the first release. What changes the price: number of roles, integrations, data migration, real-time features and compliance needs.

A concept for a professional-services firm: client documents arrive through a portal with checklists and reminders, not email attachments. Staff work from one queue with status and an audit trail.

How is this different from your Laravel development service? This service starts from the workflow and the business problem, and the stack is chosen in discovery. Laravel development is for teams that have already picked Laravel or run a Laravel app that needs specialists. Both use the same delivery standard. Why is Laravel the default back end? It gives us mature queues, testing, authentication and deployment tooling, plus a large hiring pool for whoever maintains the app later. If your team already runs Node, .NET or Django, we discuss it in discovery. If another team fits better, we say so. Should we build or buy? Buy when a SaaS product covers the workflow and its limits are acceptable. Build when the workflow is how you compete, when tools force double entry, or when per-seat fees grow faster than the team. Discovery ends with that recommendation in writing. Why is discovery paid? It produces assets you keep: a scope, a clickable prototype, an architecture note and a fixed estimate. If you build with another team, all of it goes with you. How do you estimate a build? Per release, from the scope sheet. Each feature has acceptance criteria, so the estimate covers known work. New ideas go through a written change request with time and cost before anyone builds them. Do you design the interface too? Yes. Our UX team designs the core flows for each role, including empty, error and no-access states. Where we can, we test the prototype with real users. Deeper research or a full design system is scoped as SaaS product design. How do you test and release? Automated tests run on every pull request, and a failing suite blocks the merge. Releases go to staging for your review, then to production through the pipeline. Each release has a written rollback step. Where is the app hosted, and who owns it? It is hosted in your cloud account, and the repository lives in your GitHub organization from the first commit. You hold the admin credentials. We work as invited users you can remove. Can you take over an app another team built? Yes, after a paid review of the code, dependencies, tests and deployment. You get a written report with risks and options: stabilize, upgrade in stages or rebuild parts. We do not promise a fix before we have read the code. What happens after launch? Most apps need updates, monitoring and small changes after launch. A care plan covers that with named response windows. If your developers take over instead, they get the runbooks and a recorded walkthrough. Next step ## Tell us the workflow.
