Turn “finish my app” into one testable workflow.

A fixed price is only useful when both people can point to the same finish line. Start with one person completing one task—not a list of screens that look unfinished.

This guide gives you a way to describe a small implementation job in an existing web app. It is useful whether you continue with your builder, hire a freelancer or ask AppFlowFix to review the scope. The five-case structure is our working method, not an industry certification or a claim that five tests make an app complete.

Start with an actor and an outcome

Write one sentence: “An existing [actor] can [action] and then [observable result].” For example: “An already signed-in customer can create a service request and reopen the saved request with its title and Submitted status.” This identifies a user, a starting action and something you can verify after the action.

“Build a customer portal” is not one workflow. Neither is “fix all Supabase issues.” Those phrases hide separate jobs: onboarding, authentication, permission design, data entry, notifications, reporting and billing. Each can fail for different reasons and require different access. Listing them under one heading does not make them a small assignment.

Choose the next useful outcome, not necessarily the most dramatic defect. A working request submission may let you run a small manual pilot even if the analytics screen is unfinished. Ask what a real user must accomplish next and what can remain manual without misrepresenting the product.

Draw the boundary around existing parts

Identify the starting route, the screens touched and the existing data destination. For a narrow completion job, the app should already run, the actor should already exist, and the underlying data model should be usable. If the task requires a new permission system, payment migration or an entirely new service architecture, the boundary has expanded.

For AppFlowFix’s fixed scope, the working limit is one workflow across up to three existing screens, using the existing application structure and data model. This is an intake limit, not a rule that every three-screen task is easy. A single screen can contain a difficult third-party integration or a security decision that puts it outside the offer.

Write the exclusions beside the outcome. “No signup or email delivery changes. No billing. No data migration. No new roles. No production deployment.” A useful exclusion explains where responsibility stops; it should not hide something necessary for the agreed result. If the excluded work is a prerequisite, the job is not ready for this scope.

Write five acceptance cases

Use short, observable statements. Each case needs a starting condition, an action and an expected result. Avoid “works properly,” “fast enough” and “production ready” unless you replace them with an agreed measurement and environment.

The repeated-action and failure cases must match the app’s real semantics. A note-taking app might allow two similar notes. A booking task should not accidentally create two reservations. Do not copy the sample’s expected result if it would be wrong for your users.

Five is a scoping device, not a magical coverage number. If a sixth essential behavior appears, discuss whether to replace a case, split the job or reject the fixed scope. Silently adding essential cases late makes a fixed fee ambiguous for both sides.

Choose one neighboring regression

A neighboring regression is an existing behavior close enough to be affected by the change. If you repair request creation, an older request should still open from the list. If you repair editing, creating a new item may be the neighboring check. Choose it before coding so it is not selected merely because it happens to pass afterward.

Record the baseline result. If the neighboring behavior is already broken, say so and agree whether it is a prerequisite or a separate job. Do not describe an unchanged pre-existing failure as damage caused by the new work, and do not claim that one regression check covers the rest of the application.

Make the repository handoff reproducible

Provide the authorized repository, the branch or commit to start from, the documented run command and safe test data. Confirm who may approve a change and who will deploy it. Keep credentials out of the initial brief and arrange access through an owner-managed process after fit is established.

Lovable’s GitHub integration provides code export and synchronization with a repository. Its documented synchronization behavior includes an active branch, so clarify which branch is authoritative before two people make competing edits. Git access alone is not a complete handoff: the recipient still needs a reproducible run path and the relevant test environment.

Capture your baseline before the work begins. Save the current commit, the reproduction steps and the known failures. A screenshot can explain a visible problem, but it cannot replace steps that another person can run. A short redacted recording may help where the sequence matters.

Separate diagnosis, implementation and deployment

Diagnosis answers “what is happening, where does the failure occur, and is a bounded fix feasible?” Implementation changes the agreed behavior. Deployment moves reviewed code into an environment. Aftercare handles a defined class of issues after handoff. They are related activities, but they are not interchangeable deliverables.

A cheap diagnostic offer is not evidence that an entire workflow can be completed for the same price. Equally, a large rescue package may include architecture, permissions and deployment that your single task does not need. Compare the result, exclusions and evidence you receive—not only the headline fee.

Public hiring requests for finishing existing Lovable apps show that buyers can want continuity instead of a rebuild. Some requests also include broad multi-role portals and extended work. Those are useful context for the problem category, but they do not validate a fixed price for this narrower job.

Agree on change and support rules

Decide what happens when a new requirement appears. A clean rule is to pause, describe the new requirement and choose between replacing an agreed item, quoting separately or stopping. Avoid treating every new discovery as an automatic extra charge; a contractor still owns the obligations they accepted.

AppFlowFix includes one adjustment within the accepted scope and seven calendar days for reporting a reproducible failure of the agreed cases. It is not indefinite maintenance. The implementation offer is invoiced after scope approval, and the start date is agreed separately. There is no instant slot implied by sending a form.

The handoff should contain the code change, run instructions, five case results, neighboring regression evidence and a rollback reference. Read it before considering the task accepted. If something remains untested, the report should say what and why.

Use a small brief before spending more

Copy this outline: actor; starting route; expected outcome; current failure; existing screens and data; five cases; neighboring regression; run command; access owner; exclusions; deployment owner. Fill it with one real task. If you cannot make the outcome observable, spend a little time on the definition before buying implementation.

The interactive scope worksheet keeps your draft in this browser page and lets you copy or download it. It does not send the content. When the task is ready, request a fit review. We will tell you whether it belongs in the $799 workflow offer, needs separate diagnosis or falls outside this lane.
