Excel-to-web applications
Turn spreadsheets used for approvals, calculations or reporting into a shared application. Keep the business rules, with controlled access and consistent data.
Business systems & SaaS
We build browser-based software for the work your business does every day: managing customers, processing invoices, tracking stock and running services online.
Replace a spreadsheet process, connect existing systems or develop a new SaaS product. We work directly with businesses and as a development partner for agencies.
Example workflow · order management
A connected workflow with shared records, permissions and a clear history of changes.
What we build
Our work covers internal tools, customer portals and subscription products. The features below are examples of what we can scope around your process.
Turn spreadsheets used for approvals, calculations or reporting into a shared application. Keep the business rules, with controlled access and consistent data.
Manage enquiries, customer records, follow-ups and sales activity in one place. Shape the pipeline around how your team actually sells and supports customers.
Create quotes and invoices, record payments and give staff a clear view of outstanding balances. Agree accounting rules and integrations with your finance team.
Give customers or internal teams access to portfolio information, documents and reports. Define data sources, access controls and review steps before development.
Build a subscription service with customer accounts, administration and billing integrations. Start with the core paid workflow, then extend it using customer feedback.
Track products, stock movements, purchasing and fulfilment. Connect stock records to orders and reports so staff can work from the same information.
Excel to web
The spreadsheet usually contains years of practical decisions. We review its formulas, exceptions and hand-offs before replacing it.
The first release can cover one process while the rest of the business continues working as usual. Data migration and a check against your existing calculations belong in the scope from the start.
Identify the inputs, calculations, reports and people responsible for each step.
Agree who can view, edit and approve records, including the exceptions staff handle manually today.
Import sample records, compare outputs and test the workflow with the people who will use it.
We select a stack for the application, your existing systems and the team maintaining it. A project does not need every technology on this list.
Interactive screens, forms, dashboards and administration tools.
Business rules, authentication, integrations and the services behind your application.
Structured records, relationships, transactions and reporting.
Components where performance or systems integration makes Rust a practical choice.
A working application needs more than screens. We agree the scope for APIs, permissions, migration, testing, deployment and backups, then define what support covers after launch. Agencies can bring us in for an agreed part of delivery or the full application build.
Explore agency partnerships →If an existing product meets your requirements without awkward workarounds, it may be the better choice. Custom development makes sense when your workflow, integrations or product idea needs behaviour that available tools cannot reasonably provide.
Yes. We start by reviewing the workbooks, formulas, data and users. We then agree the first workflow to replace, how records will be migrated and how the results will be checked.
We review the available APIs, data formats and access permissions before confirming an integration. This can include accounting software, payment providers, existing databases and other business tools.
We need to understand the main workflows, user roles, integrations and existing data. We use that information to define a first release and provide an estimate with the assumptions and exclusions clearly stated.
Describe the workflow, who uses it and where it gets difficult. A sample workbook with sensitive information removed can help explain the job.
