Tellum is a systems integrator
for civils and groundworks contractors.
Business systems — not the kit on site.
Your sites, gangs, plant and cash live in different places — 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 civils 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 site, three systems, three different numbers. I spend Friday afternoons working out which one is right.”
That's plumbing, not people. We fix the plumbing.
“The permit ran over by two days. Nobody flagged it — we found out when the Section 74 charge landed.”
A charge you learn about from an invoice was avoidable a week earlier. We put permit dates against what the gang is actually doing.
“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 site, cost-to-date against budget — gangs, plant, materials and muck-away — updated as costs land, with day-works and variations 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.
Re-flow for the field, Sage kept for the books, one site tracker — 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, day-works and applications.
One portal on top of NetSuite — cost-to-complete per site, day-works captured the day they happen, finance stays in NetSuite.
Permits, works and money were three separate conversations.
Permits raised in one place, progress reported in another, Section 74 charges discovered on the invoice.
One board: permits against actual progress, overruns flagged before the charge, reinstatements and defects tracked to close.
Nobody could see survey findings turning into quotes and quotes turning into work.
Money in QuickBooks, pipeline in HubSpot, the works schedule in a spreadsheet.
One weekly picture: framework call-offs, findings-to-job conversion, gang utilisation, cash by depot.
The hire bill was the only place anyone found out a machine had been idle for three weeks.
Telematics in one portal, hire desk in email, workforce and safety reporting in Excel.
One board: utilisation and idle time by machine, on-hire versus programme, safety, incidents and workforce reporting alongside.
Three acquisitions, three field systems, entities that didn't line up.
Consolidating P&L by depot and division took most of the month.
A consolidation layer on Intacct — common site 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 civils & groundworks: Re-flow, Causeway, Street Manager, Asta Powerproject, Trackunit, 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.
