Read-only ERP access, built by hand.

Your ERP runs the business. Cetari makes it answer.

We hand-build a read-only path from the ERP you already run to a warehouse your team can question—in plain English, Excel, SQL, or the BI tools they already use.

Before the ticket even lands, Cetari has the answer.

AI tools receive scoped warehouse access. They do not receive production ERP credentials.

The problem

Monday’s question. Wednesday’s spreadsheet.

Finance asks. Operations waits. IT digs through undocumented tables, old customizations, and reports nobody wants to touch.

By the time the answer arrives, the question has changed.

Every department has its own export, its own formula, and its own number.

Same company. Three answers.

“Just use AI” does not settle the argument. It repeats it faster.

Static exports are already stale. Production ERP credentials are too risky. Now the reporting problem is also a security problem.

Cetari gives finance, operations, and approved AI tools the same modeled warehouse. Access is scoped. Production ERP credentials stay out.

What Cetari does

Stop building reports. Start shipping answers.

The ERP stays where it is. Cetari builds the read-only path from its tables to the tools your team already uses.

  1. 01

    Connect

    We map the system you actually run—not the clean one described in the manual. The connection is read-only. Your ERP remains the system of record.

    ERP access: read-only

  2. 02

    Model

    We turn raw tables, custom fields, and years of business logic into definitions finance and operations can use.

    Raw tables → business definitions

  3. 03

    Serve

    Ask in plain English. Work in Excel. Build in Power BI or Tableau. Query with SQL. Approved AI tools receive scoped warehouse access. They do not receive production ERP credentials.

    Warehouse endpoints: scoped

Why hand-built

There is no magic connector.

Older ERP systems rarely have a clean API. The schema is undocumented. The customizations have customizations.

A plug-in cannot know which table matters, which field is stale, or which number the business trusts.

So we go in and wire each integration by hand.

That is not a workaround. It is the work.

The connection is hand-built. The warehouse is managed.

Who it is for

Built for companies that run on the system they already have.

Cetari is for operational businesses with older, heavily customized ERP systems that are too important to replace casually and too difficult to question directly.

These are the systems that run the floor, the warehouse, and the books—but still cannot answer a direct question without a ticket, an export, or the one person who knows which tables to trust.

The system is old. The questions are not.

Systems

Manufacturing · Distribution · Processing · Logistics

Inventory · Margin · Purchasing · Service levels

Places where inventory, margin, purchasing, and service levels are the day—not a dashboard somebody checks once a month.

Security and ownership

The fastest answer is the one IT can approve.

Read-only extraction. Isolated infrastructure. Open files. Scoped warehouse access.

01 Read-only
Cetari reads from the ERP. It never writes back. The ERP remains the system of record.
Connection: read-only
02 Single-tenant
Each customer gets isolated storage and compute. Customer data is not pooled.
Storage + compute: isolated
03 Open exit
Data lands in open Parquet files. Inspect it. Query it. Take it with you.
Format: .parquet
04 Scoped access
AI tools query governed warehouse endpoints. Production ERP credentials stay out of them.
ERP credentials: excluded

Bring us the question your ERP won’t answer.

Not the polished one. The real one—the margin question, the inventory question, or the number that changes depending on who exports it.
