Custom Web Application Development
Dashboards, portals, and internal tools that replace the spreadsheets and duct-taped SaaS running your ops.
Who this is for
If any of this sounds like you, we should talk.
Your team lives in a spreadsheet that has outgrown itself
Tabs are referencing tabs. Formulas are breaking. People are emailing screenshots. You need a real app with permissions, validation, and history.
You stitched together five SaaS tools and Zapier is melting
Every new hire needs five logins. Data lives in five places. Reporting is impossible. A custom app gives you one source of truth.
You need a client portal, not a Dropbox link
Customers want to log in, upload, approve, and pay in one place. Off-the-shelf portals do not match your workflow. A custom build does.
You need an internal tool that fits how you actually work
Admin panels, ops dashboards, approval workflows, and operational tooling that turn manual processes into one-click flows.
What changes for you
Outcomes you can point to, not features you can ignore.
- A single tool that replaces the spreadsheet, the email chain, and the three SaaS subscriptions.
- A workflow your team adopts in days because it matches how they actually work.
- Real audit logs and permission control instead of shared logins and Slack DMs.
- Reporting in seconds instead of an hour of copy-paste every Friday.
What is included
Scope, organized by phase.
Discovery (Phase 1 of 5)
Phase 1
Discovery
What we lock down in this phase before moving on.
- Workflow mapping with the team that will actually use the tool
- Data model and integrations inventory
- Permission model (who sees what, who can do what)
- Build vs buy decision audit
How an engagement works
From hello to handoff, step by step.
You book a workflow audit call
We watch how your team actually works today, including the workarounds. The build follows the real workflow, not the org chart version.
We send a scoped plan within 48 hours
Fixed scope, fixed timeline, integration list confirmed, and a clear before-and-after picture.
We build in 2-week sprints
Every sprint goes to a staging environment your team can click through. Feedback comes in weekly, not at the end.
We migrate your data and train your team
We move you off the spreadsheet, the old tool, or the email thread. We sit with the team on launch day.
We hand off with docs and a care plan option
Repo, credentials, runbooks, and 30 days of bug fixes on us. Continue with a care plan or take it in-house.
Case study
Spottle
A live two-sided booking marketplace Spottle owns outright, built to fit its model and grow with it.
Spottle needed a custom two-sided marketplace that off-the-shelf tools could not give it: guests booking creative spaces by the hour, hosts listing spaces and managing availability, and transparent pricing built into every flow.
We built Spottle as a custom web application on a modern stack (Next.js, React), with listing and booking flows for both sides of the marketplace, city and category browsing, host onboarding, and the account and policy plumbing a live platform needs.
Why us
What you get with WitsCode that you don't get elsewhere.
We map your workflow before we open an editor
Custom apps fail when they match what people say they do instead of what they actually do. We sit with the team first, sketch second, code third.
Last-mile engineering, not happy-path demos
Bulk imports, edge cases, undo, audit logs, weird permissions, offline-friendly inputs. The stuff a real internal tool needs and a demo skips.
We integrate with what you already have
Your CRM, your email, your Slack, your Stripe, your warehouse. The app fits into your stack instead of replacing it.
WitsCode rebuilt our Shopify store so it finally converts the traffic we were already getting. They understand speed and storytelling in equal measure, and the store has been a real growth lever since launch.
Frequently asked
Questions before you reach out.
A website mostly shows content. A web app lets users log in, do things, and change state. Web apps need auth, permissions, data validation, and workflows that websites do not.
Most internal tools and portals ship in 6 to 14 weeks. Complex multi-role workflows can run longer. We give you a firm timeline at scoping, not a guess.
Yes. HubSpot, Salesforce, Stripe, Slack, QuickBooks, Google Workspace, Microsoft 365, and most APIs are routine work. We confirm the integration list during scoping.
Web apps work on mobile browsers by default. If you need a real mobile experience (offline, push notifications, camera), we can scope a React Native build as a follow-on.
Yes. Full IP transfer per milestone, repo access, and credentials handed over on completion.
Yes. Code audit first, written assessment, and an honest call on what to keep, what to fix, and what (rarely) to rewrite.
Yes, standard mutual NDA before technical conversations.
