# What changes with the integration on

_With an ERP integration enabled, the Billing screen gains a Service Order column showing each invoice's sync status._

When your store has an **active ERP integration** (VHSYS, Bling, etc.), TecPet starts showing the **sync status** of invoices with the external system. The most visible change is on the **Billing** screen.

## The new column: Service Order

In the **Billing** list, the **Service Order** column shows, for each invoice, **where it stands in VHSYS** — from becoming a Service Order to having the invoice issued. It's your quick thermometer of what is (or isn't) in sync with the ERP. Below, what each state means.

## What each state means

The column uses the same states as VHSYS. The possible ones:

- **Processing** — the invoice is being sent to VHSYS (a momentary state);
- **Open** — it already became a **Service Order** in VHSYS, as a receivable **not yet paid**;
- **Fulfilled** — the Service Order was **paid** in VHSYS;
- **Awaiting Issue** — it's ready for the **invoice** to be issued;
- **Issued** — the **invoice** was issued successfully;
- **Canceled** — the invoice / Service Order / note was **canceled** (and the cancellation reflected in VHSYS);
- **Error** (red) — the sync or the issuing **failed** and needs attention (see below what to do).

Invoices not in the fiscal/ERP flow show **"—"**.

## Services and products in the ERP

In the ERP, TecPet organizes the invoice into two document types:
- **Service Order (OS)** — for the visit's **services**;
- **Sales Order (PV)** — for the **products** (which also **reduce ERP stock**).

An invoice with services and products can generate both. (Details in *VHSYS integration*.)

## When Error shows up

1. Open the invoice and check the **customer record** (Tax ID, name, address, phone) — a mismatch is the #1 cause;
2. **Fix** whatever is wrong in the customer record;
3. **Reprocess** the invoice.

If the error persists (or it's many invoices at once), it may be the ERP connection — **contact support**. See also *VHSYS integration* and *Inside an invoice*.

> **⚠️ Heads up**
>
> If the **Service Order** column shows **Error** (in red), that invoice **didn't sync** with the ERP and the invoice **won't be issued**. It's almost always a **divergent customer record** — fix the record and reprocess the invoice.
