Guardians of the exchange

Every exchange needs a guardian.

Money, cost data, files and AI output move between systems all day. Makara Works builds the tools that stand at the gate — reading what comes in, checking that it adds up, and handing it on in the shape the next system needs.

The legend behind the name

The makara guards the gate where two worlds meet.

For more than two thousand years, the makara has been carved over temple gateways across Asia — half creature of the sea, half of the land. It stands at the threshold and decides what passes.

We took its job literally. Every Makara Works tool sits at a gateway between two systems — your bank and your budget, the factory floor and the P&L, one cloud and another, a document and the AI reading it — and guards what crosses.

What crosses the gate

Any shape in · checked · the right shape out

Transactions

Bank statements, payments, invoices and ledgers — reconciled before they're trusted.

PDF · CSV · OFX

Cost & engineering

BOMs, routings, rates and quotes — every number traced back to its source.

XLSX · BOM · RATES

Software to software

ERP exports, spreadsheets and APIs mapped from one system's shape to another's.

CSV · JSON · API

Cloud storage

Files moving between drives, buckets and backups — versioned and accounted for.

DRIVE · BUCKET · SYNC

AI applications

Documents read by AI, then checked by rules — model output is verified, not assumed.

LLM · OCR · REVIEW
The Makara method

Three jobs at every gate.

The same discipline runs through every product in the family, whether the data is a bank statement or a bill of materials.

01

Receive

Read data in whatever shape it arrives — PDF, CSV, Excel, JSON or an API — without asking the sender to change.

02

Guard

Validate, reconcile and flag anything that doesn't add up — before it reaches a decision, a report or a customer.

03

Translate & deliver

Hand it on in the shape the next system needs, with a trail showing where every number came from.

The family

One gate. A family of keepers.

Each product guards a different crossing. They share one mark, one method and one standard: the numbers have to add up.
