Supply chain management (SCM) software
Every number shows its working.
SIAARU is supply chain management software for manufacturers: a control tower that prices the stockout, the late shipment, the idle container and the supplier drifting off-contract — in rupees, today. Every one of those numbers was computed from your own records in SQL, and arrives with the arithmetic that produced it.
Your own data, from a CSV export. Thirty minutes. No commitment.

This is how every number in the product appears: the figure, the inputs, the row count and the date. A model can explain it. A model cannot produce it.
The film
Forty things are late. One costs money today.
Filmed on the demo organization's data. Nothing to fill in.
One yard, one screen
From the ship's side to the shelf.
A container is discharged, cleared, stacked, picked and loaded, and somewhere in that chain a duty-free licence is being drawn down, a bill of lading is not in hand, and a truck is running late. SIAARU watches the whole of it and tells you which one costs money today.
The walkthrough
How it works.
The whole product, filmed as it runs: the control tower, an exception opened and priced, promise checking, the planner. Narrated, unhurried, nothing staged that the product does not do — and every part of it is listed, module by module, on the modules page.
Filmed on the demo organization's data. Tell us who is watching and it plays — no account, no card.
The exception feed
Most readings are unremarkable. The work is finding the one that is not, before it costs you — and being able to show why it was flagged. Four different people open this screen for four different reasons; what each of them sees first is a page of its own.
Live lanes
Every lane you run, and the day it slips.
Shipments are read from your TMS and your carriers, milestone by milestone. When a promised date moves, the exception is raised against the orders behind it — so the first person to hear about a delay is you, not your customer.
- Your ports
- On plan
- ETA slipped
Illustrative lanes. Live carrier tracking is in build — see what we don’t do.
How it works
Five steps, and the fifth feeds the first.
Each step is a real stage in the product, not a diagram. The numbering is the order the work actually happens in.
Connect
SAP, Oracle Fusion, Dynamics 365, your WMS or TMS, a database, or a spreadsheet. Read-only.
Reconcile
Units converted, currencies converted, duplicates found, gaps named. Data below your quality threshold is quarantined, not silently used.
Measure
Fill rate, OTIF, DIO, supplier performance, freight cost per tonne — computed in SQL, each with its formula attached.
Forecast
Ten models compete per material and the winner is chosen on periods it never saw. Accuracy is reported held-out, against a benchmark.
Act
Exceptions ranked by rupee impact, a recommended action, an approval, an audit row. Then the loop measures whether it worked — from a desk, or from the same product installed on a phone.
Three claims, each with its receipt
If we say it, we show the arithmetic.
Determinism
The KPI engine cannot reach a model.
Not a policy — a test. The build fails if the KPI or forecast engine imports an AI client, the database, the network, or the clock.
forbidden imports: 0
build blocks on failure: yes
Isolation
One tenant cannot read another.
Every query for business data goes through a single scoped accessor. The organisation always comes from the session and never from the request.
the only sanctioned data path
isolation suite: dedicated, in CI
Accountability
Every change has a name against it.
Who, what it was before, what it is now, and why. Administrator actions write a row the tenant can see.
actor · before · after · reason
retention: 7 years, enforced
Measured, not projected
Numbers from our own test runs.
These are results we can reproduce, on a seeded tenant. They are not customer outcomes — we say so plainly because we do not yet have customers.
Accuracy is reported as held-out, using WMAPE weighted by volume — an average of per-item percentage errors flatters a forecast by letting tiny items dominate. The benchmark is shown beside it because an accuracy figure with nothing to compare it to is a number, not a result.
Connects to
Your systems, read-only by default.
Built to each vendor's published protocol and tested against it. The entity paths are published defaults, and confirming them against your gateway is the first task of any deployment — which is why every one of them is editable. Writing back is a switch you turn on per connection, and then only three actions reach your ERP — expedite, cancel, requisition — each after a person has approved it.
SAP
S/4HANA and ECC over the OData gateway. Basic authentication or OAuth 2.0 via BTP.
Oracle Fusion
Cloud SCM over the REST framework, with its own paging.
Dynamics 365
Supply Chain Management over OData v4, with Azure AD client credentials.
WMS and TMS
Any system exposing a JSON collection. You choose the format and give the paths.
Also: Zoho Books and Inventory, SAP Business One through its Service Layer, your SQL data lake on PostgreSQL, MySQL / MariaDB or SQL Server (read-only, one query per entity), any REST endpoint, CSV and Excel. Every outbound URL is checked before it is fetched — loopback and cloud metadata addresses are refused.
Free, and no sign-in
Try the arithmetic before you try us.
Six calculators, each answering a question an exporter or a forwarder works out by hand every week. Each is a copy of arithmetic running inside SIAARU, taken from the same file rather than written a second time — and each says which figure is missing instead of filling the column. Nothing you type leaves your browser.
- Export obligation exposure
- Landed cost
- Demurrage and detention
- Chargeable weight
- Container fill
- GST place of supply
Straight answers
What SIAARU does not do yet.
A gap you find yourself costs us the deal. A gap we tell you about costs us nothing.
- It reads your ERP. It does not write back into it. SIAARU recommends raising the purchase order; a person raises it in SAP.
- Its own books are not your statutory books. The Ledger posts journals from records SIAARU already holds — no hand-keyed entry — and closes periods. Opening balances, depreciation, payroll and year-end adjustment are not in it. Tally or your ERP remains the book of record, and the ledger exports to it rather than replacing it.
- The connectors are not vendor-certified. They implement each vendor's published protocol and are tested against it, but no live customer tenant has been connected yet.
- Live carrier tracking is being wired now. Shipment milestones today arrive by import or from your TMS. A tracking integration with GoComet is the next piece of work.
- Not SOC 2 certified. The technical controls an audit examines are in place and the policy set is written. The certification and its observation window are not. Here is exactly where we stand.
