Critical processes live in fragile workbooks
Pricing, planning, costing or reporting depends on files that only a few people understand—and that break when something changes.
We modernise spreadsheet-driven business systems using the most appropriate combination of technologies—so your workflows stay reliable, collaborative and fit for purpose.
There is no single replacement for Excel. Every client is different. Some systems should remain primarily Excel. Some should move into Microsoft 365. Some benefit from Office Scripts, APIs or cloud applications. Most projects become a hybrid of several technologies.
The solution should always fit the business—not force the business to fit the technology.
Organisations often recognise themselves in one or more of these situations.
Pricing, planning, costing or reporting depends on files that only a few people understand—and that break when something changes.
Multiple copies circulate. Nobody is sure which file is current. Mistakes creep in and audits become difficult.
Teams need simultaneous access, controlled permissions and clearer hand-offs than shared drives and email can provide.
Managers wait for someone to update a workbook before they can see performance, costs or capacity.
Data is re-typed between Excel, accounting, CRM and operational systems—wasting time and introducing errors.
The person who built the macros or models is leaving—or already overloaded—and the business cannot afford downtime.
XLS Experts designs hybrid business systems. We start from the process—not from a preferred platform—and recommend the architecture that reduces risk while preserving what already works.
Spreadsheet modernisation projects commonly include:
Job tracking, job costing, resource planners and status boards that have grown beyond a single user’s control.
Quote engines and cost models that need clearer rules, audit trails and controlled updates.
Month-end packs and KPI workbooks rebuilt as reliable reporting pipelines feeding dashboards.
Processes that start in Excel and graduate into secure internal applications when volume or users increase.
Legacy automation reviewed, stabilised or replaced with Office Scripts, Power Automate or API-backed workflows.
Eliminating duplicate entry between spreadsheets, accounting systems, CRM and operational databases.
Most organisations do not jump from a spreadsheet to a full web application in one step. Progress is staged.

Clients may adopt one stage or several, depending on requirements, risk and budget.
Use this framework to understand when each option is appropriate. The goal is to educate—not to push a single product.
| Factor | Improve Excel | Extend Microsoft 365 | Office Scripts | Hybrid Architecture | Dedicated Web Application |
|---|---|---|---|---|---|
| Summary | Structure, validation, documentation and clearer models inside the workbook. | SharePoint storage, Lists, Forms and Power Automate around existing Excel logic. | Cloud-friendly automation that reduces brittle desktop macros. | Excel for modelling, databases for shared data, automation for hand-offs. | Purpose-built screens, permissions and workflows with spreadsheet export where useful. |
| Best for | Specialist analysis, low concurrent users, fast iteration. | Team collaboration with familiar Microsoft tools. | Repeatable workbook tasks in Microsoft 365. | Most mid-size operational systems. | High concurrency, field users or customer-facing processes. |
Technology supports the business process. A project may combine several of these complementary tools rather than choosing one “winner”.
Spreadsheets, Microsoft technologies, APIs and cloud databases work together. We design systems where each layer does what it does best.
Modern business systems commonly integrate through APIs—with Microsoft 365, Google Workspace, accounting, CRM, internal databases and third-party software—to eliminate duplicate entry, improve reporting and automate workflows.
Depending on the project, we may use Microsoft SQL Server, PostgreSQL (including Supabase), Google Firestore or Azure SQL. Spreadsheets, cloud databases and web applications can coexist in the same solution.
Where hosting is required, solutions may be deployed on Microsoft Azure, Google Cloud Platform (GCP) or Amazon Web Services (AWS)—selected according to project requirements, not as a branding exercise.
Case studies for spreadsheet and process modernisation projects will appear here as they are published.
