If your warehouse team scans a pallet at 3pm and the ERP doesn’t catch up until tomorrow’s overnight import, you haven’t got one source of truth. You’ve got two systems arguing in slow motion. Sales quotes stock that isn’t really there. Finance spends the next morning reconciling differences nobody can explain. And the warehouse manager ends up fielding both phone calls.
That lag between the floor and the ERP is where a lot of UK distribution operations quietly lose money, and closing it is what TBO4 is built for.
What “one source of truth” actually means
Walk into most UK warehouses and you’ll find stock recorded in three places: the ERP, a spreadsheet somebody on the team keeps, and the head of whoever has been there longest. The three rarely agree.
So when we talk about one source of truth, we mean something fairly specific. A scan on the floor updates the ERP in the same second it happens, not in the same hour and not in tonight’s batch run. Sales can see genuine available-to-promise stock while they are still on the phone to a customer. Finance closes the month without sending someone off to find a missing pallet. And the warehouse manager stops being the human bridge between two systems that ought to be talking to each other directly.
The ghost stock problem
The clearest example of why any of this matters is ghost stock: inventory the ERP swears you have but the warehouse can’t lay hands on, or the other way round.
It creeps in from all over. A picker takes from the wrong location and nothing flags it. Returns come back through the door but never get receipted properly. Damages get written off on the floor and never make it to the ledger. Or the old favourite, where something gets counted twice at stock take and the variance simply goes down as “unexplained”.
Most UK distributors we deal with carry a few percent of this as background noise. It is small enough to wave away on any given day, and big enough over a year to tie up real working capital in stock that was never on the shelf. The part that does the lasting damage is when that phantom figure quietly works its way into next year’s buying.
Share one continuous record between the WMS and the ERP, so every scan, adjustment and movement lands in the same place, and ghost stock has nowhere left to hide. There is no anxious month-end reconciliation, because there is nothing left to reconcile.
Which UK ERPs TBO4 connects to
We’ve built REST-based connectors for the ERPs that actually turn up in UK operations:
- Acumatica, which we are seeing more and more of with 3PLs and mid-market distributors
- Sage 200 and Sage Intacct, the default across a lot of UK SMBs for years now
- SAP Business One, common through UK manufacturing and distribution
- Microsoft Dynamics 365 Business Central, the one growing fastest in our own pipeline
- Oracle NetSuite, usually at the larger end of the SMB market
- MYOB EXO, which you mainly run into in UK groups that have an Australian parent
And if your ERP isn’t on that list, TBO4 will still talk to it. The REST API tends to turn a one-off integration into a few weeks of work rather than a six-month saga, and we have done enough of them to be straight with you about the timeline up front.
What changes for the warehouse, in plain language
Most of what changes after a TBO4 go-live never shows up on a boardroom slide. You see it on the dock and in the back office.
The pickers notice first. Everything is on the handheld now, so there are no paper pick sheets, the next item is already on screen, and if someone reaches into the wrong location the scan catches it before they have taken two steps. The warehouse manager swaps the 7am report that was always a day out of date for a live view of picking, putaway, inbound and exceptions that stays open through the shift.
Finance tends to notice at the next month-end, usually with some relief. Reconciliation that used to eat days comes down to minutes, and it becomes a case of confirming the number rather than hunting for it. Sales stop hedging too: when they tell a customer something can ship today, they are reading the same figure the warehouse is.
Where to start
You don’t need a six-month programme to get most of the benefit. A TBO4 rollout in a UK warehouse, when it goes to plan, runs over roughly eight weeks. The first fortnight goes on the ERP integration and getting master data mapped. The next couple of weeks set up locations, racks and rules. After that comes a pilot on a single product family with a small team, and then the full go-live.
Few projects hit those dates to the day. A messy data set, or a fortnight when half the team is on holiday, and everything shifts to the right. The shape holds, though.
If one thing predicts how well it goes, it isn’t the WMS or the ERP. It is whether someone owns data hygiene from day one. Clean master data and the deployment is largely uneventful. Messy data, and that is the conversation worth having first, before anyone even opens the WMS.
