## Short answer

TOTVS Protheus is an ERP from TOTVS, a Brazilian software company, widely used by Brazilian and Latin American manufacturers, distributors and service firms. It is known for deep Brazilian fiscal coverage and for being highly customisable through the ADVPL / TL++ programming language. Its modules are traditionally identified by SIGA-prefixed names such as SIGAEST and SIGAPCP.

## Overview

Protheus grew from the Microsiga product line, which TOTVS acquired and developed into one of its core ERP platforms. TOTVS also sells other ERP lines, such as RM and Datasul, aimed at different segments, so Protheus is one product among several. It is common in manufacturing, distribution, retail, agribusiness and services in Brazil.

A defining trait is customisability. Customers and partners extend the standard system through ADVPL, a proprietary xBase-style language, and its object-oriented successor TL++, which lets them add entry points, reports and custom logic. This flexibility is a major reason for its large local partner base, but it also means heavily customised installations can become hard to upgrade.

In a manufacturing stack, Protheus typically covers purchasing, inventory, production planning and control, costing, maintenance, billing, finance and Brazilian tax obligations such as electronic invoicing and the SPED digital bookkeeping reports. MES, WMS, PLM and equipment systems connect through REST services, web services or database-level interfaces, and TOTVS offers BPM and analytics tools in its wider portfolio.

## Best For

- Brazilian and Latin American manufacturers that need local fiscal compliance built in
- Mid-size discrete and repetitive manufacturers with heavy customisation requirements
- Companies with existing Microsiga or Protheus estates upgrading to current releases
- Distributors and manufacturers that combine production with complex tax scenarios
- Organisations supported by the large Brazilian TOTVS partner network

## Modules

### Inventory and costing (SIGAEST, SIGACUS)

**Description:** Stock control, warehouse movements, valuation and product costing.

### Production planning and control (SIGAPCP)

**Description:** Bills of material, routings, MRP, production orders and shop-floor appointments.

### Purchasing (SIGACOM)

**Description:** Requisitions, quotations, purchase orders and receiving.

### Billing and sales (SIGAFAT)

**Description:** Sales orders, pricing, invoicing and electronic invoice issuance.

### Financial (SIGAFIN)

**Description:** Payables, receivables, bank reconciliation and cash management.

### Accounting and fiscal (SIGACTB, SIGAFIS)

**Description:** Ledger, tax books and statutory reporting for Brazilian requirements.

### Maintenance (SIGAMNT)

### Quality (SIGAQIE and related)

**Description:** Inspection and quality control functions connected to receiving and production.

## Deployment

Available on-premise, in private hosted environments and as a TOTVS-operated cloud offering. Many existing customers run it on their own infrastructure with a partner.

## Integrations

### REST and web services

**Detail:** Protheus exposes REST services and supports SOAP web services, and custom endpoints can be written in ADVPL / TL++.

### Database access

**Detail:** Data is stored in a relational database accessed through TOTVS's DBAccess layer; direct reads are possible but should respect the data dictionary and vendor guidance.

### Electronic invoicing

**Detail:** Integration with Brazilian tax authorities for electronic invoices is handled through TOTVS fiscal services.

### Fluig and BPM

**Detail:** TOTVS Fluig is the vendor's platform for workflow, collaboration and process automation alongside the ERP.

### MES and shop floor

**Detail:** Production appointments and orders are exchanged with MES or machine-data layers through services or middleware.

### Flat files

**Detail:** Import and export routines and EDI-style files are common for banking and partner exchanges.

## Strengths

- Deep Brazilian tax, fiscal and statutory coverage
- Extensive customisation through ADVPL / TL++
- Large local partner and developer community
- Broad functional coverage from manufacturing to finance to maintenance
- Flexible deployment choices

## Limitations

- Heavy customisation can complicate upgrades and support
- Outside Latin America, partner presence and documentation are limited
- Proprietary development language means a narrower talent pool than mainstream languages
- User interface and architecture reflect a long product history, depending on release

## Alternatives

- SAP Business One
- SAP S/4HANA
- Oracle NetSuite
- Microsoft Dynamics 365 Business Central
- Sankhya

## Ai Opportunities

- Natural-language questions over stock, production orders and receivables, with the SQL shown for review
- Assistants that explain ADVPL / TL++ customisations and entry points to speed up upgrade analysis
- Reading supplier invoices and delivery documents and proposing entries for human approval
- Summarising production and stock exceptions for planners each morning
- Private open-weight models hosted beside an on-premise Protheus installation

## Selection Tips

- Inventory existing customisations and entry points before planning any upgrade
- Confirm the fiscal content you need is covered by your release and subscription
- Check which TOTVS line (Protheus, RM, Datasul) fits your segment rather than assuming
- Test production planning and costing with your own routings in a scripted demo
- Decide early between on-premise, hosted and TOTVS cloud, including backup and integration implications
- Choose a partner with proven manufacturing references and upgrade experience

## Faq

### What is TOTVS Protheus?

**Answer:** It is an ERP from the Brazilian vendor TOTVS, used mainly by Brazilian and Latin American manufacturers, distributors and service companies. It is known for deep local fiscal coverage and for being extensible through the ADVPL / TL++ language.

### What are the SIGA modules?

**Answer:** SIGA is the traditional prefix for Protheus modules, for example SIGAEST for inventory, SIGAPCP for production planning and control, SIGAFAT for billing and SIGAFIN for financials. Modules map to functional areas and are licensed and configured individually.

### How do I integrate with Protheus?

**Answer:** Common routes are its REST and web services, custom endpoints written in ADVPL / TL++, middleware, and controlled database access. Which route fits depends on whether you need real-time transactions or reporting reads, and on your release version.

### Is Protheus on-premise or cloud?

**Answer:** Both. Many customers run it on their own servers or in partner-hosted environments, while TOTVS also offers cloud delivery. The choice affects upgrade cadence, integration options and who manages infrastructure, so confirm it during contracting.

### Can AI be used with Protheus?

**Answer:** Yes. Typical uses are a read-only natural-language query layer, assistants that explain custom code, and agents that prepare invoice or order entries for approval. Models can run privately next to an on-premise installation so data stays inside your network.
