# What integrations are

_How TecPet connects to ERPs and management systems to sync customers and issue invoices automatically._

TecPet **talks to your ERP/management system** so you don't do the work twice. With an active integration, customer registration and the fiscal/financial side flow between TecPet and the external system automatically.

## What an integration does

Depending on the ERP, the integration can:
- **Sync customers** — the record created in TecPet goes to the ERP (and, in some, comes back too);
- **Generate the fiscal/financial side** — creates the service order, installments and receivables in the ERP from TecPet's invoices;
- **Issue the invoice** automatically when billing;
- **Bring data back** — in two-way integrations, counter (POS) sales and receipts from the ERP come into TecPet.

## In two directions

- **TecPet → ERP** (most): TecPet sends customers and invoices to the ERP;
- **ERP → TecPet** (two-way, like VHSYS): the ERP returns customers, POS sales and receivables so TecPet stays in sync.

## Supported ERPs and systems

TecPet integrates with several systems, including: **VHSYS**, **Bling**, **Omie**, **Conta Azul**, **Gestão Click**, **Sankhya**, **Zanthus**, **iClub** and others. The two most common have their own article: [VHSYS integration](/en/configuracao/integracoes/integracao-vhsys/) and [Bling integration](/en/configuracao/integracoes/integracao-bling/).

## How to enable it

The integration is **set up by the TecPet team** (with your ERP credentials) — you don't enable it yourself from the panel. **Contact support** telling them which system you use to connect your account.

> **⚠️ Heads up**
>
> For the **invoice** to go out without errors, keep the **customer record complete**: correct **Tax ID**, **name** and **address**. A record that diverges from the ERP is the **#1 cause** of issuing failures.
