Repeated entry and calculations
Define input rules, calculations, and output formats so information can move directly to the next step.
ERWIN STUDIO / Custom Software Development
Custom Software Development
Erwin Studio offers custom software development focused on practical workflows. Start with the people, data and steps involved, then discuss useful features, integrations, acceptance checks and deployment. Explore our product enquiry interface and Baccarat testnet development project as concrete examples.
Discuss Custom Software Development projectDescribe the problem before deciding on features
“We need a system” becomes useful when it is broken into questions: who enters information, when does it move to another person, and what needs checking or approval? Mapping those steps reveals whether a simple tool or a shared system is needed.
Status and handoffs
Set states, permissions, and exceptions before deciding how the interface and notifications should work.
Data between systems
Confirm available interfaces, access, formats, and recovery from failed or duplicate transfers.
Turn scope into work that can be accepted
- Record the current workflow. Use a real example to show inputs, processing, and results.
- Choose first-stage features. Separate essential work from improvements that can come later.
- Confirm data and exceptions. Include empty inputs, invalid values, connection failures, duplicate actions, and access levels.
- Accept against examples. Review agreed scenarios, deployment, administration, and future update responsibilities.
Understand practical functionality through existing work
Product enquiry interface
Our metal card page validates quantities, calculates a subtotal, and creates an enquiry message. It turns repeated manual information gathering into a small, usable interface.
Try the product enquiry interface →Baccarat: smart contracts and interaction flow
The Baccarat project documents a Sepolia testnet contract, game phases, and front-end interaction. It is a testnet development example, not a production security audit or commercial system.
Read the Baccarat development project →Handoff is more than a screen
Agree who manages code and data, how deployment works, how account access is handled, and what documentation is needed. External platform accounts, restrictions, and ongoing costs should be clear too.
Bug fixes, dependency updates, and future features can be arranged around how your product operates after launch.
QUESTIONS BEFORE WE START
Before we start
What is the difference between custom software and a standard website?
A presentation website focuses on content and enquiries. Custom software also handles data, user actions, changing states, or business workflows. The two can be combined when a site needs more than information display.
When is custom development worth considering?
Consider it when existing tools cannot support an essential workflow or when manual copying, checks, and tracking have become a real obstacle. Weigh process change, migration, and ongoing maintenance before deciding.
Can it connect with existing platforms?
We first need to confirm APIs, import/export options, permissions, data formats, and platform restrictions. A platform name alone cannot guarantee an integration.
Do I need a complete specification before development?
No. Begin with one real workflow, the people involved, the data in use, and the outcome you want to improve. Features, edge cases, and acceptance checks become precise before development starts.
How are cost and development time estimated?
Data handling, permissions, integrations, screen count, and testing all affect the effort. We separate essential first-stage work from later improvements before estimating.
How are deployment and ongoing maintenance handled?
Cloud and deployment can be part of the project. Account ownership, backups, environments, updates, and support responsibilities are agreed separately from development work.
START WITH YOUR NEEDS
Share your project scope first
No need to start with a full spec. Share your context and goals, and we can prioritise together.
- How work is completed today, which steps repeat or cause errors, and who will use the new tool.
- The data that needs to be entered, viewed, and exported. Please remove customer or other sensitive data from examples first.
- Existing systems, integrations, essential features, budget range, and desired timeline.
