Tellum is a systems integrator
for site services contractors.
Business systems — not the kit in the yard.
Your contracts, your fleet, your crews and your 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 site services 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 contract, three systems, three different numbers. I spend Friday afternoons working out which one is right.”
That's plumbing, not people. We fix the plumbing.
“Four hundred cones went out. Two hundred and sixty came back. Nobody invoiced the difference.”
Loss and damage is revenue you're owed, not a cost of doing business. We reconcile what went out, what came back and what got recharged — per contract, per week.
“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 asset and every crew shift against its contract — hire due versus invoiced, off-hire requests versus collections, transport movements booked against the day's runs. The meter and the invoices finally agree.
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.

About to buy an ERP they'd have spent a year fighting.
Sage 50, a dozen spreadsheets and a WhatsApp group.
Re-flow for crews and equipment, Sage kept for the books, one contract tracker — live in six weeks.
Hire ran in one system, finance in another — margin per contract lived in neither.
inspHire for the desk, NetSuite for the books, a monthly argument about which was right.
One portal on top of both — revenue, utilisation and recharge per contract and per depot, finance stays in NetSuite, the desk stays in inspHire.
Every unit needed a weekly service run; the routes lived in someone's head.
Deliveries, collections and service visits planned on a whiteboard, fuel and waste logged on paper.
One board: every unit's location, service visits due and done, delivery and collection runs planned against the fleet, utilisation by depot.
Nobody could see enquiries turning into hires and hires turning into cash.
Money in QuickBooks, pipeline in HubSpot, the hire desk in a spreadsheet.
One weekly picture: quote conversion, utilisation by asset class, overdue returns, cash by depot.
Shifts, equipment and what came back were three different conversations.
Crew shifts in the field system, equipment counts on paper, loss discovered at stocktake.
One board: shifts delivered against booked, equipment out and back per contract, loss and damage recharged weekly — with safety and workforce reporting alongside.
Three acquisitions, three hire desks, one fleet nobody could count.
Consolidating P&L and utilisation by depot took most of the month.
A consolidation layer on Intacct — common contract structure, one fleet view across depots, month-end 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 site services: inspHire, MCS, Point of Rental, Re-flow, BigChange, Trackunit — 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.
