Niki ScarthOffice administrator, SME Building Services LtdCroydon · on Unibuild since 2023
Read the SME case studyIt has always been a pleasure to work with Darshan and his team to create our completely bespoke system, which I can only describe as brilliant.
The system is constantly growing and improving. Whenever we need something added or changed, whether it's a new form that would work better for us or a new idea to improve the way we work, Darshan works his magic and makes it happen!
It has genuinely changed the way we work for the better, improving our record-keeping, automating processes and standardising practices across the company, saving us both time and money.
It's also improved the service we provide to our clients, who love being able to view their job and asset information live, at the click of a button.
Thank you, Unibuild!

Records connected to the work.
The common theme is a shared record at the point of entry.
A record made on site or at the counter
EMS’s site measures, SME’s gate scans, RailCore’s clock-ons and C&G’s counter invoices illustrate different ways to capture a record near the work.
A check connected to the record
A recorded contract allowance, a named purchase approver or an account balance gives the person entering a record something to check against.
A system developed in stages
SME started with the core system in 2023. Timesheet approvals followed in late 2024, clock-in on the phone in early 2025 and purchase ordering in February 2026. C&G began with a catalogue in November 2017 and is still being added to.
Different implementations, different scope
EMS, SME and RailCore run the main platform. C&G is a bespoke merchant implementation.
