Software built, improved, or taken over — at a price you agree to first
How we help your business
Custom software development is the core of what 1902 Software does: AI agents that act inside business workflows, automation connected to existing IT systems, custom CRM and quoting tools, and internal or client-facing applications.
We also improve existing systems, support certain platforms, connect software that needs to exchange data, design interfaces, test releases, and advise clients before a build or major technical decision.
Custom software development
1902 Software designs and builds software around your requirements, typically as a Fixed Price Project. If you want to be hands-on in shaping the prototype before committing the full build, Co-Dev is our collaborative option where we teach you how to use agentic development tools, so you can collaborate with us before scoping the production build.
Our development work includes:
- Websites structured for SEO/AEO/GEO
- Ecommerce sites that are agentic-commerce ready
- AI agents and workflow automation connected to existing systems
- Business systems, client portals, and custom CRM or quoting tools
- Web and mobile applications for employees, field teams, and clients alike
- APIs and integrations that move data and trigger actions across systems
- ERP, CRM, PIM, inventory, marketplace, payment, and shipping integrations
- Software that combines business rules, operational data, and human approval
- Other custom software solutions
Improving existing software
Software rarely stands still after launch. Through Continuous Monthly Development, 1902 Software handles the stream of fixes, improvements, upgrades, and new functionality that keeps an existing system useful as the business around it changes.
Typical work includes:
- Bug fixes and new functionality
- Performance, security, and database improvements
- Platform upgrades and workflow automation
- API and business-system integrations
- Design and usability improvements
- Server setup, configuration, and installations
- AI implementation
Design
Design work covers the parts of a system that people see and use. 1902 Software can create a new interface, improve an existing user journey, establish a design system, or prepare campaign and landing-page graphics.
Our design services include:
- UI design and UX improvements
- Ecommerce, website, and mobile app design
- Landing pages and design systems
- Conversion optimization and split testing
- Accessibility improvements
- Graphic design, campaign graphics, and promotional materials
- Other digital design work
Testing
Professional testing reduces the risk of releasing a change that breaks an important workflow. 1902 Software combines AI-assisted coverage with experienced QA engineers, including hands-on testing where context and judgment matter.
Our testing services include:
- Test planning and functional testing
- Regression and performance testing
- User acceptance and compatibility testing
- AI-assisted and manual testing
- Bug verification and release validation
- Other testing appropriate to the software and release
Advising and strategy
Some engagements begin with a technical decision rather than a development task. 1902 Software helps clients evaluate an idea, define requirements, review architecture, choose technology, plan an AI implementation, or decide how an existing process should change before software is built.
- Technical advice and project planning
- Software architecture and technology recommendations
- AI strategy
- Software reviews
- Business-process improvements
- Requirements gathering and Project Scoping
- AI implementation and other software and technology decisions
Taking over existing projects
1902 Software regularly takes over websites, webshops, business systems, and mobile apps developed by another company or agency.
Before development begins, 1902 Software reviews the existing solution, becomes familiar with the codebase and its dependencies, and recommends a practical route forward. The goal is to stabilize critical workflows, remove obstacles to future development, and create a clear modernization path without interrupting day-to-day operations.
From prototype to production and ongoing improvement
Shape, Build, Care describes three connected ways to work with 1902 Software, not a required sequence. Co-Dev lets you shape an optional prototype with us, a Fixed Price Project builds the production software, and Continuous Monthly Development cares for it after launch.
You can start wherever your needs fit. A Project Manager recommends the route that fits the work, the amount of hands-on involvement you want, and the level of ongoing collaboration needed.
Co-Dev
Co-Dev is a collaborative development process for custom software when you want to be hands-on. Together, you and 1902 Software build and shape a working prototype with agentic development tools. It can be a new application or a feature for an existing system, shaped around your workflow and design system.
We usually move from project intake to a working prototype within one to two weeks. Before shaping, we run one workshop with two sessions to teach you how to use agentic development tools so you can make changes on your own. During the shaping phase, 1902 Software advises on features and technical decisions, makes changes with you, and remains responsible for production readiness.
If you've already vibe-coded a proof of concept, you can bring that to us instead, and we'll use it as the starting point for the same review and production process.
The prototype is not the finished product; it is where we settle exactly what to build. It proves how the software should work and provides a concrete basis for the scope and fixed price. The production build then adds the engineering a live system needs, such as authentication, a real data model, integrations, security, scaling, testing, and deployment.
Fixed Price Projects
A Fixed Price Project is one defined undertaking: a new webshop, a mobile application, a major upgrade, or a platform migration. One scope, one agreed price for the whole thing, fixed before development begins.
A Co-Dev engagement flows to a fixed price project, or you can go straight here if you want a more hands-off approach. We define the scope and agree on the expected deliverables, then based on everything we have learned, we calculate the price using our AI-powered estimation tool and careful manual review. Large projects typically start with a Project Scoping phase at an agreed, prepaid fixed price. Its outcome is the exact definition of what will be built, including the final price. Clients also occasionally come to us with a complete, fully specified project plan where scoping isn't needed.
Continuous Monthly Development
After a project is delivered, or for businesses with existing software that simply needs ongoing attention, Continuous Monthly Development (CMD) keeps your software and systems moving forward. You send tasks whenever they arise, and we handle them. CMD is available in three plans:
- Care, where everything runs in writing at one fixed monthly price. No estimates to approve, no cost overruns. One task at a time, for work you can simply describe and hand over. Each month you get the output you would normally expect from one experienced specialist.
- Care Plus, everything in Care at its own fixed monthly price, plus up to two hours of meetings per month with a Project Manager or any 1902 Software expert, for planning, advice, and technical discussion, up to two ongoing tasks at a time, and up to two developers working on your tasks at the same time.
- Care Ultimate, for ongoing engagements, often across multiple systems, that need close collaboration. A fixed price for every task or group of tasks, approved by you before work begins, and people with the right expertise added to your project as your needs grow. Meetings with any 1902 Software expert are available whenever you need them (billed at $80 an hour for the actual time spent).
In plain terms: if you have a modest, steady workload, Care or Care Plus is your least expensive option. Care Ultimate will cost more than Care or Care Plus, because it is designed for a different purpose: larger engagements with bigger scope, where we advise, prototype and test where needed, and set up and configure everything from a single server to a complete distributed cloud architecture on AWS or Azure.
One thing never changes, on any plan or on any Fixed Price Project: every task is handled by the best person for the task, whether that means a developer, a designer, a tester, an AI expert, a software architect, or a digital marketing expert. What changes between the plans is how much communication your work needs, how fast things get done (one ongoing task in Care, two in Care Plus, and virtually no limit in Care Ultimate), and how the price is shaped.
How we use AI in our work
1902 Software uses AI and agentic tools across planning, design, development, and testing. These tools help with research, implementation, checking, and documentation, while experienced people control access, verification, release, and responsibility.
1902 Software generally works with Claude, Codex, Manus, Grok Bot, GitHub Copilot, Cursor, and Windsurf, alongside 1902 Software’s own models, skills, and workflows. We can also work with tools your team is comfortable using.
Every solution is reviewed, tested, and verified by experienced software developers and testers before delivery. Where judgment or possible harm is involved, human review remains part of the decision.
