Tellum is a systems integrator
for joinery manufacturers.
Business systems — not workshop machinery.
Your orders, drawings, workshop hours 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 joinery 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 order, 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 job looked profitable when it left the workshop. Then the site hours landed.”
A bespoke job's margin is decided twice — on the bench and on site. We show both against the estimate while you can still act.
“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 order, estimated against actual — design hours, bench hours, site hours, materials — as they're booked, with drawing approvals by status and delivery dates against the client's programme.
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, CabinetVision in the shop, and a dozen spreadsheets in between.
One order tracker from enquiry to install, Sage kept for the books, the shop software left doing what it's good at — live in six weeks.
Order controls lived in an eight-tab workbook next to the ERP.
NetSuite for finance, Excel for hours, materials, approvals and delivery dates.
One portal on top of NetSuite — estimated versus actual per order, approvals by status, delivery dates against the programme, finance stays in NetSuite.
Every doorset needed a certificate trail; every request meant a day in the files.
Certification records in folders, labels logged on paper, delivery records separate again.
One record per doorset: certification, label, delivery and install — attached as it happens, answer in minutes when the building owner asks.
Nobody could see surveys turning into quotes and quotes turning into workshop slots.
Money in QuickBooks, pipeline in HubSpot, the shop schedule on a whiteboard.
One weekly picture: quote conversion, slots booked against capacity, deposits due, cash by client.
Install dates were promises; the workshop found out last.
The programme in one tool, the shop schedule in another, and a Friday meeting to argue about both.
One schedule, backwards from every install date — load by section, clashes visible weeks out, with workforce and safety reporting alongside.
Three acquisitions, three workshops, order books that didn't line up.
Consolidating P&L and shop load by site took most of the month.
A consolidation layer on Intacct — common order structure, one view of load across workshops, 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 joinery: CabinetVision, Microvellum, AutoCAD, Smartsheet, Payapps, 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.
