Custom development
Custom development: from a requirements assessment to project acceptance
Turn storefront visuals, workflows, and third-party integrations into a custom project with a clear estimate, acceptance process, and support boundary.
Custom development is for a defined business problem, not an open-ended promise to build anything. Projects may cover storefront visuals, workflows, payment or logistics integrations, other systems, and reporting.
Write down the job before estimating it
Describe who does what, under which condition, and what should happen next. For example, specify which fields reach an inventory system after an operator imports a product. "Integrate inventory" is not enough to estimate or test the work.
Put the project terms on paper
Confirm the scope, interfaces and data permissions, schedule, pricing, acceptance criteria, launch window, and support model. For an external system, confirm the available APIs, test environment, and change-notification process as well.
Leave room to roll back
Scope, timing, pricing, acceptance criteria, and ongoing support are set in the requirements assessment and project contract. Run user acceptance on the core flows and prepare a rollback plan before moving unverified custom work into production.
