Overview

Staying in control as a fast-moving field operation.

Kilmac is a civil engineering and groundworks contractor based in Scotland. With over 180 employees and multiple offices and worksites, reliable connectivity is essential for everyday seamlessness.  

Like many UK construction businesses, it was losing control of its mobile spend one small charge at a time - before discovering plan.com.

We spoke to Laney McDonald, who oversees Kilmac's company mobile devices. She told us how plan.com and Indigo Unified Communications put Kilmac back in control.

Challenge

The need for visibility.

Kilmac's costs were rising. The main cause was data overage charges on individual connections.

“With our last mobile provider, costs were rising and surprise fees came out of the blue.”

Without real-time usage data, Kilmac were blind-sided with out-of-allowance charges. The team could not see the charge, or what it was for, until the bill arrived at the end of the month.

Solution

Visibility anytime, support when it matters.

Kilmac met with plan.com partner Indigo Unified Communications and liked their approach straight away. Indigo focused on solving the issues Kilmac actually had.

They recommended going with plan.com, which offered a shared data solution to mitigate overage and keep costs down. The selling point, however, was the ability to be informed of their usage at any time – made possible by the my.plan platform.

Indigo manages Kilmac's mobile and SIM connections, so Laney's team does not have to chase the detail. "Indigo let us know our data usage every week, so we never go over our allowance."

Support does not stop when the working day ends either.

“Indigo has been available out of hours to help with last-minute international bolt-ons.”

Results

Predictable costs with no surprises.

With Indigo and plan.com, Kilmac now has predictable monthly costs and no surprise fees. Shared data keeps costs down. Out-of-hours support covers last-minute needs. Weekly usage updates keep allow the team to make fully informed decisions, not guesses.

The result is a mobile service Kilmac no longer has to worry about, so the team can focus on the work, not the bill. “Now we have a consistent, predictable plan with no surprises.”
