Excel, Access and VBA consultants building reporting and automation tools for small to medium companies


Custom Solutions builds business process software, mostly for accounting, and it takes two routes into a client's work. It can join the client's own team, or it can deliver a complete solution on its own infrastructure. The firm says it prefers long-term cooperation on complex problems.
Each engagement starts with an audit and analysis of the client's current situation, so the solution is designed around how the business actually runs. The firm says its expertise lets it produce a full picture of the business before proposing anything.
A data science department builds reporting, graphs and forecasts from a client's own information. One example described a costing system for building projects, where each project takes many user inputs and the system keeps around 50,000 parameters to run hundreds of formulas.
One project turned R scripts that calculated financial indicators for a factoring company into T-SQL. The firm says the scripts were ported successfully and that it then recommended improving the original sources, because they were hard to read.
Support and maintenance covers troubleshooting end-user problems and adding features over time. The firm also places developers inside a client's in-house team, and runs an internship programme for developers who are starting out in .NET.
