Finance Automation for Sage
Sage holds your nominal ledger; it can't tell you whether last week's job made money. We build the layer that can — a production platform allocates 101,000+ toll transactions to exact trip legs, reconciles fuel cards against telemetry, and maps every cost to Sage nominal codes. It surfaced a €41,000 cost gap in its first months.
Key Takeaway
Sage holds your nominal ledger; it can't tell you whether last week's job made money. We build the layer that can — a production platform allocates 101,000+ toll transactions to exact trip legs, reconciles fuel cards against telemetry, and maps every cost to Sage nominal codes. It surfaced a €41,000 cost gap in its first months.
What We've Built Around Sage
An Irish pan-European road freight operator ran finance across five disconnected systems — transport management, telematics, fuel cards, toll feeds, ferry invoices as PDFs — and reconstructed job costs by hand in Excel, weeks after the jobs ran. Sage 50 held the ledger; nobody could say what any given trip actually cost.
We built a platform that computes true per-job profitability automatically: it allocates 101,000+ toll transactions to the exact trip legs they belong to, reconciles ~9,500 fuel-card records a year against vehicle telemetry, reads ferry invoices with AI document extraction, and maps every cost to Sage nominal codes so the ledger and the job-costing view always agree. In its first months it surfaced a €41,000 cost gap nobody knew existed.

The Approach: Source Data First, Sage Kept Clean
The reframe that makes this work: cost data is born in operational systems — the fuel card, the toll transponder, the telematics unit — not in documents typed up afterwards. The platform goes to those sources directly, computes the allocation deterministically (the same answer twice, every time, explainable to an auditor), and uses AI only at the unstructured edges, like reading a ferry operator's PDF invoice.
Sage's role doesn't change: it remains the nominal ledger and the system of record. The platform reads Sage through a REST layer over its data, and its computed costs carry the client's own nominal-code mapping — editable by the finance team in a settings screen, not hardcoded — so everything reconciles to the ledger without the automation ever putting the books at risk.
What This Gives a Sage Shop
Sage 50 and 200 are kept deliberately simple, which is why they're everywhere in owner-managed and mid-market businesses — and why the work around them sprawls into spreadsheets. The automation layer gives you what the ERP upgrade salesman promises, without the migration:
- Live job or project profitability instead of a month-later Excel reconstruction
- Automatic cost allocation from the systems where costs are born
- Anomaly surfacing — the €41,000 gap was found by the system, not by an accountant with a hunch
- A clean ledger — Sage stays authoritative, and the mapping to nominal codes is explicit and editable
And because the platform is separate from the ledger, it survives a future ERP move: the same architecture maps to Dynamics 365 F&O by swapping the posting adapter from Sage nominal codes to D365 F&O cost categories and WBS elements.

Does This Only Apply to Freight?
No — freight is just where the proof is (see the freight & logistics industry page). The pattern applies wherever costs are born in operational systems and jobs need true profitability: plant hire and equipment rental, field services, construction subcontracting, distribution. If your team reconstructs job costs in Excel from exports, the shape of the problem is the same regardless of the industry label.
Where to Start
Start with the AI readiness assessment: we'll map which systems hold your cost data, how clean it actually is (never fully — that affects sequencing, not feasibility), and what the first automated allocation should be. Or describe your month-end job-costing routine and we'll tell you what a build would look like against your Sage setup.
Frequently Asked Questions
Which Sage products do you work with?
The production build runs against Sage 50; the same architecture applies to Sage 200, reading through a REST layer over Sage's data. The workflow platform is independent of which ledger feeds it, so the Sage edition mostly determines the connector, not the build.
Does the platform post into Sage automatically?
The ledger stays under the finance team's control. The platform computes allocations and carries every cost with its mapped nominal code, so what reaches Sage is deliberate and reconcilable — the automation never writes to the books behind your back.
Our costs come from systems you've never heard of. Is that a problem?
Almost certainly not. The freight build reads a transport management system, two fuel-card providers, tolling feeds, telematics and PDF ferry invoices. If a system has an export, an API or even just documents, it can feed the platform — AI extraction handles the unstructured end.
Is this worth it for a smaller Sage business?
The economics work when manual reconstruction is eating real hours or masking real costs — the freight build found €41,000 on its own. Run the automation ROI calculator with your own numbers, or take the free assessment; if an off-the-shelf tool fits your process better, we'll say so.

Job Costing Automation with Sage: Real-Time Project Profitability
Sage holds your books; your job costs live in fuel cards, timesheets, supplier feeds and telematics. Reconstructing profitability by hand in Excel means you find out whether a job made money a quarter late -- if at all. Here's the source-data-first pattern that fixes it, from a production build.
guideJob Costing and Project Profitability on Dynamics 365 Finance & Operations
D365 F&O's Project management and accounting module knows what's been posted to a project. It doesn't know what a piece of plant cost today, what a subcontractor is about to invoice, or whether a change order was ever priced. Here's where native project accounting stops being enough, and the architecture that closes the gap, from a production build.
