Tellum is a systems integrator
for M&E contractors.
Business systems — not the ones you install.
Mechanical, electrical and public health run the same job from three sets of numbers — and someone has to stitch them together every week.
We join what you already run into one live picture.
Nothing gets replaced.

The systems your M&E business already runs on.
If it's on this list, we've connected it before. If it isn't, we probably still have — .
You're not unusual. This is what running a contractor at this stage looks like.
“Same job, three disciplines, three sets of numbers. I spend Friday afternoons working out which one is right.”
That's plumbing, not people. We fix the plumbing.
“Mechanical says the job's fine, electrical is over, and I find out which at the CVR.”
A discipline you can only compare at month-end can't be steered. We show all of them against the same job, weekly.
“Month-end takes the FD a week and one spreadsheet nobody else understands.”
Month-end shouldn't be a build project. It should already be there.
Wherever you are with your systems, there's a version of this for you.
You're picking or replacing something.
We help you choose the tools that fit how you actually work — not the ones the salesman liked. Shortlist, trial, decision. Then we set them up properly.
You already have the tools. They don't talk, or they don't do enough.
We customise, connect and extend what you run: integrations, missing reports, automations, the layer on top. Then we keep it working and growing with you.
You have the systems. People use half of them.
We teach your team to run the tools you already pay for — properly, and with the automations that make them worth the money.
Most clients start in the middle. Some start with training and never need the rest.
Tools get you level. The layer gets you ahead.
Choosing, connecting and training put the right tools in place — the same tools your competitor can buy. The Tellum Operating Layer is ours: it sits on top of what you run and bends to how you work. A new metric lands in days, a new workflow in a week or two. Nothing gets replaced.
One live picture. Three things on it.
Every contract, cost-to-date against budget and split by discipline — mechanical, electrical, public health — labour, materials and plant updated as costs land, with variations and day-works where you can see them.
Nothing gets replaced. Your ERP stays your ERP. We add the layer on top.
Small first step. No migration. Nobody retrains.
We sign an NDA, then walk you through what we'd connect and how. A demo, not a sales call.
We pick the right technical approach and build a working prototype on your numbers — free, typically within 48 hours. Static data at this stage; the live connection comes with the build. You decide if it's worth going further.
Implementation, customisation, the connecting layer, training — the actual engagement begins. Your systems stay where they are; your team keeps working the way it works.
Before and after
Examples of what we can help you with — real engagements, anonymised, names and some details changed.
6 of 6 engagements
About to buy an ERP they'd have spent a year fighting.
Sage 50, a dozen spreadsheets and a WhatsApp group.
SimPRO for works and maintenance, Sage kept for the books, one contract tracker across the disciplines — live in six weeks.
Cost value reconciliation lived in an eight-tab workbook next to the ERP.
NetSuite for finance, Excel for procurement, cost-to-complete, variations and applications — one tab per discipline.
One portal on top of NetSuite — cost-to-complete by discipline against one job, variations captured the day they happen, finance stays in NetSuite.
Three sources, three answers to “how did the contracts do?”.
Joblogic for works, Intacct for the books, a five-day month-end in Excel.
One reporting layer: contract profitability by discipline, labour recovery, utilisation, retentions — nightly.
Nobody could see PPM findings turning into quotes and quotes turning into work.
Money in QuickBooks, pipeline in HubSpot, the PPM schedule in a spreadsheet.
One weekly picture: renewals, remedial-to-job conversion, engineer utilisation, cash by branch.
Every main contractor's project manager asked for the same numbers every Monday.
Progress and safety in Procore, workforce and competency reporting in Excel.
Progress, safety, incidents, cards and competencies and workforce reporting in one place, fed from Procore and ADP.
Three acquisitions, three project systems, entities that didn't line up.
Consolidating P&L by branch, division and discipline took most of the month.
A consolidation layer on Intacct — common contract structure, month-end across all entities in days.
Want to see the layer itself? Same numbers, three front-ends — inside NetSuite, as a modern portal, as Power Apps.
You're probably here the way most of our clients arrive — a colleague passed our name on, or you got a note from me. Either way, good to meet you. If the page doesn't answer your question, ask me directly — I read every reply myself.
Questions we get asked
The stack we see most often in M&E: Procore, Eque2, COINS, Trimble Estimation, SimPRO, Sage — plus Excel, Microsoft 365 and WhatsApp. In total we work with around 160 systems across 21 categories, listed at tellum.works/vendors. If a system has an API, a database or an export, it can be connected.
