Compare App Development Quotes: Scope and Handoff

One vendor calls the job “development complete.” Another prices discovery, design, QA, and deployment separately. Put those totals side by side and you still do not know which proposal costs more. First make sure every vendor is quoting the same outcome.

Normalize the scope before you compare prices

Check whether each proposal covers:

• a web app only, or native iOS and Android apps as well
• the agreed screens, user flows, and admin features
• design source files, responsive layouts, and accessibility work
• legacy data migration and third-party integrations
• testing, security review, and bug-fix scope
• server deployment and app-store review support
• warranty fixes and paid maintenance after handoff

A missing line item can turn into a change order later. The reverse also happens: a quote may include platforms or ongoing support you do not need. Build a comparison table with three columns—included, excluded, and assumed—rather than comparing vendor names and totals alone.

Treat the prototype as a conversation tool, not a specification

A prototype built with Claude Code, Codex, Cursor, or Lovable can show the intended flow more clearly than a written brief. A working screen is not automatically a complete specification, and its code is not automatically production-ready.

Lovable, in particular, builds web applications. A PWA or a separate wrapper can offer an installable mobile experience, but a web prototype should not be counted as progress toward a native iOS or Android app without further assessment.

Separate what the prototype proves from what remains unknown.

Already demonstrated

• the screen flow and core copy
• the main actions users need to take
• the preferred visual direction

Still to assess

• whether the code is reusable
• behavior across mobile devices and browsers, including accessibility
• the safety of authentication, authorization, and payments
• testing, deployment, and monitoring architecture
• licenses for libraries and assets

This keeps the prototype useful without overstating its value, and saves you from explaining settled product decisions all over again.

Buy a short technical assessment before the full build

No one can responsibly promise that “80% of the current code is reusable” or that “everything must be rebuilt” without examining the repository. Agree on a paid assessment and its deliverables first.

At minimum, ask the reviewer to check:

1. whether the project installs and runs in a clean environment by following the README
2. whether the key screens and flows still work
3. whether secrets appear in code or logs, and whether authentication or per-user authorization has obvious gaps
4. what is covered by automated tests and what still requires manual checks
5. which dependencies, hosting services, external accounts, and licenses the app relies on

Ask for three paths: finish in place, refactor selected areas, and rebuild. Each path should state its scope, risk, and schedule. A prototype does not guarantee a discount, but rough code is not worthless either. The assessment tells you what can actually be reused.

The handoff package is more than the repository

A new developer should be able to start on the day they receive access. Prepare:

• a README with install, run, and build commands
• the names of required environment variables and where to obtain them; send real values through a separate secure channel
• a screen and feature inventory, plus known defects
• test accounts and test steps
• a list of server, domain, payment, analytics, and app-store accounts
• the Git repository and commit history that records important decisions

Do not delete duplicated or apparently unused AI-generated files immediately before handoff. Preserve the known-working state in a tag or branch first, then confirm deletions during the assessment.

Never commit a .env file containing real values or API keys. Keep a value-free .env.example that lists only the required variable names. If a key has already been committed, revoke or rotate it first, then consider cleaning the Git history.

Put operational control in the contract

Teams get locked into a vendor when account ownership and deliverables were never made explicit. Get written answers to these questions before signing:

• Which repository receives the source code and full Git history?
• Whose legal account owns the domain, hosting, app stores, and payment provider?
• Are editable design files, fonts, images, and paid licenses included in the handoff?
• Which features form each acceptance milestone, and what counts as approval?
• Who approves scope changes, how are they recorded, and how are they priced?
• What qualifies as a warranty fix, and what becomes paid maintenance?

Create core accounts in the client’s name whenever possible, then grant the vendor only the access it needs. If an existing GitHub repository must change owners, include GitHub’s transfer process and a post-transfer permissions check in the handoff plan.

A short request for quote is enough

We have a working web prototype and a Git repository.
Target: responsive web app with an admin area
Scope to quote: code assessment, authentication and payment review, deployment, and handoff documentation
Excluded: native iOS and Android apps
Deliverables: source and Git history, deployment configuration, README, and test results
Please begin with a paid assessment, then price the finish-in-place, targeted-refactor, and rebuild options separately.

Send the same document to every vendor and keep their questions and answers. The easiest proposal to compare is not necessarily the cheapest one; it is the one that makes its omissions and handoff terms explicit. Before choosing a vendor, consider having a contract professional review the schedule, payment terms, intellectual-property language, and license clauses.
