The decision platform for
enterprise performance.
Nervay unifies manufacturing cost, budget, and forecast workflows with sales, retail, and profitability analysis — into one integrated decision layer. ERP data and operational detail are processed in real time, giving the entire organization a single source of truth.
Plan. Simulate. Decide. All on one platform.
Cost data exists.
But a single financial truth doesn't.
From production to sales, from budget to forecast, multiple "truths" run in parallel at every layer of the org. The ERP says one thing. Operations lives a different reality. Finance builds yet another model.
The result: cost, budget, sales, and profitability tell different stories — inside the same company.
By the time it reaches the CFO, the divergence is impossible to trace. Decisions get made inside this fragmented picture, with partial visibility.
This is not a reporting problem.
This is not a performance management problem.
This is an end-to-end decision-system problem.
01 · Data inconsistency
Enterprise data lives in silos: ERP, Excel, and operations each produce a different reality. As a result, decisions are never in sync.
- Nervay turns this fragmented landscape into a single deterministic pipeline — a coherent decision layer from master data to CFO metrics.
02 · Memoryless systems
A small fix made today turns into a major unknown a few weeks later. No one remembers why — and the system can't remind them.
- Nervay logs every override, versions it, and makes the full history replayable in retrospect.
03 · Delayed insight
Cost reports close on the 10th of the month. Procurement decisions don't wait. Pricing doesn't wait. The organization moves on lagging data — and the results get analyzed only after the fact.
- Nervay re-runs the full planning and cost pipeline on demand. Fresh scenarios in seconds, not at month-end.
One pipeline. One cost truth.
The entire organization.
Nervay runs a deterministic, multi-stage cost pipeline in minutes — from raw data all the way to the live cost dataset the CFO opens on Monday morning.
Every stage is defined.
Every data point traces back to its source.
Every manual intervention is logged and verified.
This is the cost architecture finance teams have spent years modeling with fragmented tools — rebuilt at enterprise scale.
A reporting layer at real-BOM scale
Nervay surfaces cost at the most granular level through virtualized rows, sticky identity columns, per-row heatmaps, and sparkline indicators. Multi-dimensional analysis by period, stage, and breakdown converges in a single surface.
- Filter. Pin. Slice.
- Reorganize the view, not the data.
- Export the full output to Excel without changing the underlying data model.
Bad data stopped at the door
Nervay's controlling rules deterministically audit every input file at the first stage of the pipeline. Missing records and renamed columns aren't just detected — they're flagged with a diagnostic that traces back to source.
This isn't a system that reports errors; it's a decision gate that catches them the moment they form.
- No bad data moves silently downstream.
- No corruption seeps into the CFO dataset.
Nervay Rules — adapts to your workflows
"Our processes vary by scope" — sound familiar? No problem.
With Nervay Rules, the rules you define from the interface restructure your data within minutes. Regardless of scenario or period, your cost and planning logic updates and ships in a controlled rollout.
We show the math.
Most planning tools hide it.
Decision systems lose their trust the moment they become a black box.
Nervay is the opposite. Click any cost, budget, forecast, or profitability number; the entire structure behind that value unfolds — inputs, applied rules, calculation stages, version history, and timestamps.
The flex of Excel.
The discipline of an ERP.
In today's systems, control drifts to Excel because that's where the speed lives; ERP brings safety but loses flexibility. Nervay merges both in a single platform layer.
Controllers don't change a number — they activate a rule. A yield is overridden, a scenario runs, a final report is redefined — every operation is isolated in the Cost Rules platform layer.
In Nervay, you don't edit a spreadsheet — you add behavior to the platform.
- No change breaks the pipeline.
- No intervention breaks the audit chain.
# Per-scenario sidecar applied at the end of stage 008. # Below: "Lower Sep 2026 energy on Forging group by 10%" rule = CostRule( name = "Forging Sep 2026 energy −10%", scope = CostRuleScope( metric = "Energy", cost_type = ["COGS"], category = ["Forging"], date_from = "2026-09-01", date_to = "2026-09-30", ), operation = CostRuleOperation( type = "multiply", value = 0.90, ), enabled = True, ) # Pipeline next-run picks it up automatically. store.put(scenario_id, [rule])
Simulation becomes the default workflow.
"What-if" is no longer a quarterly analysis project. It's the standard way cost, budget, and profitability decisions get made on Tuesday afternoon.
With Nervay, the organization moves beyond systems of record into a live decision surface that procurement, FP&A, and the CFO use every day. Scenarios don't wait — they're generated, compared, and made actionable on demand.
This isn't a reporting tool —
it's a decision mechanism.
The future of finance isn't producing reports — it's producing decisions.
Shorten your reporting cycles, accelerate decision speed and flexibility.
With Nervay, reframe your data not as a reporting layer, but as a live decision surface.
