Frequently Asked Questions

Need a more specific answer?

Contact us

Yes. We review the repository, running setup, designs, data model, integrations, and known failures before estimating. The first milestone names a complete user workflow, acceptance checks, dependencies, and deferred work. A prototype with reproducible setup gives us a clearer starting point than screenshots alone.

The available development budget is separate from a fundraising target. We reduce the number of workflows before removing essential access, testing, deployment, or recovery work. The estimate identifies assumptions and external dependencies. In the bill-review example, upload, correction, approval, and reporting form one release; forecasts and payment collection wait. See the worked specification.

A defined integration, release deadline, or missing specialist skill can justify a bounded engagement. Your team keeps product decisions and supplies system access and domain review. Flatlogic delivers the agreed code, tests, and operating notes. Ongoing technical leadership still needs an owner after that work ends.

Ownership, repository access, third-party licenses, and handover deliverables are set in the development agreement. A practical handover includes setup instructions, tests, deployment steps, data migrations, and known limitations. Acceptance can include another developer starting the application and deploying a change. Generator and template license terms remain separate. Review generator license terms.

A specific limitation drives that decision: unsupported logic, data access, performance, or recurring workaround cost. If configuration or a small integration solves it, the current stack can stay. Moving to code adds data migration, parallel checks, user retraining, and cutover work. The estimate includes that disruption.

A named engineering owner reviews changes, regression tests, releases, and unresolved defects. Maintenance scope separates routine updates from new features and defines the support arrangement. For Watt Footprint, Flatlogic documents continuing product delivery, QA, staging review, and releases after the initial build. Read the Watt Footprint delivery example.

A fixed-scope milestone can be estimated separately from evolving product work. Reviews use working software and agreed acceptance examples. A scope change records its cost and schedule effect before it joins the milestone. The domain expert reviews business decisions; developers own implementation and tests.
