Business Central for construction — costs, retainage and change orders under one ledger.
We configure Business Central around the way projects actually bill and bleed — not the way a demo assumes. Fifteen-plus construction implementations, run by engineers who have sat through a construction month-end.
How you get paid decides how the project has to be modelled. These are the four we see.
General contracting
Most cost arrives as subcontractor commitments, so committed cost and subcontractor retainage carry the project, not your own labour.
Specialty trade and subcontracting
Your own crews and equipment are the cost base, you are the one being held, and progress billing against someone else’s schedule sets your cash flow.
Design-build and engineer-to-order
Design hours are billable project cost, and the scope moves while the work is happening — so change-order discipline is the whole margin story.
Owner, developer and self-perform
Capitalisation, draw schedules and multi-entity ownership matter more than crew productivity, and the ledger has to survive an audit years later.
The processes, by name
If your controller uses the word, we implement the thing.
Job costing, WIP and retainage first — they are what a construction controller judges an ERP on, and where a general-purpose implementation usually stops.
01
Job costing and WIP
Cost codes, committed cost and work-in-progress schedules that tie to the general ledger — not a spreadsheet reconciled at month-end.
02
Retainage
Held on both sides: what your clients hold on you, and what you hold on subcontractors — tracked and released on the schedule the contract says, not the schedule someone remembers.
03
Change orders
Priced, approved and reflected in the forecast before the work happens — so margin doesn’t leak between versions of the contract.
04
Three-way match
Purchase order, receipt and vendor invoice reconciled line by line. A mismatch raises a legible exception — it never posts a wrong figure quietly.
05
Progress billing and revenue recognition
Percentage-of-completion or completed-contract, driven from the cost that has actually posted, so the revenue on the income statement is the revenue the job earned this month.
The part that gets tested
The paperwork that holds up payment
Construction cash flow is rarely lost on price. It is lost on documents that were not ready when the draw was due.
Lien waivers and compliance documents
Tracked against the subcontractor and the payment, so a missing waiver stops a cheque before it leaves rather than after the draw is refused.
Multi-entity and joint ventures
Separate legal entities, shared jobs and intercompany cost transfers modelled properly, so consolidated reporting does not need a rebuild every quarter.
Audit trail on every revision
What the budget was, what changed it, who approved it and when — recoverable years later without asking the person who happened to be there.
Vendor invoice to posted purchase invoice, inside Business Central. The invoice is treated as a claim and reconciled against BC’s own order and posted receipt, so a mis-read number raises a legible exception instead of posting a wrong figure.
An AI process-capture platform. A Chrome extension records what you actually click; the guide writes itself — narrated, in four reading modes, shareable by link. Includes a Business Central assistant that explains the screen you are on, cited to Microsoft Learn.
Every app above is implemented by the team that built it — one contract, one
accountable engineering group.

Straight answers
What construction buyers actually ask us.
Including the ones where the honest answer is that we are not the right firm.
Business Central isn’t construction software. Why not buy a construction ERP?
Sometimes you should, and we will say so. Business Central is the right answer when you want one ledger for the whole company and construction-shaped project accounting on top of it. It is the wrong answer when your business is estimating and takeoff first and accounting second. That is a fit-phase conversation, not a sales one.
Does Business Central handle retainage natively?
Payables retainage and receivables retention are both workable in standard Business Central once the posting setup is right, and getting that setup right is exactly the kind of thing that is cheap in week three and expensive in month eight. The half that is usually missed is subcontractor retainage — what you hold, not what is held on you.
How do change orders stay tied to the original budget?
Job budgets are versioned and the change order posts against the job, so the current forecast and the original contract are both still answerable. The failure mode we are designing against is a budget that gets overwritten and a margin nobody can explain.
Can we keep our estimating and takeoff software?
Usually yes, and usually you should. The integration point is the approved estimate becoming the job budget — one interface, cleanly defined, rather than replacing tools your estimators are fast in.
Our field staff will not use a new system.
Correct, if it is a desktop ERP screen. What field staff can be asked to do is a small number of specific things — time, receipt of material, a photo against a cost code — and those need to be simple enough to do on a phone in a hard hat. Everything else stays in the office.
How long does a construction implementation take?
It depends on entity count and how much history moves, and anyone quoting a duration before the fit-gap is guessing. What we will commit to before then is the shape: a fixed, priced scope at the end of the fit phase, and a go-live that includes your first month-end close rather than ending the week before it.
Talk to an engineer who has closed a construction month-end.
Thirty minutes, not a deck. We’ll tell you whether standard Business Central covers it, whether one of our apps does, or what a build would honestly take.
