Invoicing and e-Factura connected to your site: how to automate documents after an order

The most annoying part of an order is not the sale, it is what comes after: you open your invoicing app, copy the name, the tax ID, the address, the products, issue the invoice, email it, and then upload it to the SPV for e-Factura too. Three times a day, fine. Forty times a day, at night, you end up with a pile of un-issued invoices and a client asking "where is my invoice?".

Since 1 January 2025, according to Romania's Ministry of Finance, e-Factura is mandatory for sales to individuals (B2C) too, not just between companies. That means the document has to reach ANAF's SPV, not only the client. The good news: this whole chain can be wired straight into your site, so you never touch the keyboard.

What "invoicing connected to your site" means

The idea is simple: your site does not create the invoice itself, it sends an order to the program that knows how to make it legally. The order lands on the site, and the site automatically sends the data to Oblio, SmartBill or FGO. The program issues the invoice, files it in the SPV for e-Factura, and emails it to the client. You see it all done, without typing a thing.

The flow looks like this:

• The client places the order on the site (shop or form)
• The site sends the data to the invoicing app, via its module or API
• The invoice is issued with your series and number, fiscally correct
• The e-Factura goes to the SPV automatically, without you logging into ANAF
• The client gets the PDF by email within seconds

Our working rule: any step you do by hand more than ten times a week is a step that has to disappear.

Online shop: the ready-made module

If you run a WooCommerce shop, this is the easiest case. Both Oblio and SmartBill offer a ready-made module: you install it, enter the connection details (email + the API key from your invoicing account) and that is it. For every paid order, the invoice is issued on its own and goes to the SPV.

A few things that matter in practice, so it runs clean:

• Product codes (SKUs) on the site must be identical to those in the invoicing program, otherwise the invoice comes out with the wrong products
• VAT rates must be set the same in both places
• Individual vs. company — the checkout form must ask for the tax ID when the client is a company, so you do not issue a B2C invoice when it was B2B

If you sell simple products and want everything automatic from day one, a Shop from 690 € with the invoicing module dialed in takes the biggest headache out of the back of the sale.

Presentation site or form: possible without a shop

You do not need a full shop to automate invoicing. Many service businesses — a clinic, a workshop, a consultant — take orders through a simple form or a payment button. Invoicing can be wired there too.

When someone fills in the form and pays, their data can go straight into Oblio or SmartBill via API, and the invoice leaves just as automatically as with a shop. It is ideal for a Presentation site (490–890 €) that takes a few orders a day and does not want the complexity of a whole shop.

Oblio vs. SmartBill: in short

Both do the same main job — issue the invoice and send it to the SPV for e-Factura, automatically. The choice depends more on your accountant and on what you already use. A few points:

• Oblio — free WooCommerce module, open API, direct e-Factura integration once you enter the token from your digital certificate
• SmartBill — very widespread, invoices to individuals are automatically included in what is sent to the SPV since 2025, without changing settings
• FGO — another option with an API, the integration architecture is almost identical

Our honest advice: ask your accountant what you already use, and we connect the site to that. You do not switch invoicing programs for the sake of the site.

What it costs to connect invoicing to your site

The cost of the integration is not in the site, it is in how cleanly the data has to flow. Here are our reference points:

The invoicing program (Oblio, SmartBill) has its own subscription, separate from us — usually a few tens of euros a year. We connect the site to it.

If you first want to see what a site costs in general, we have a separate guide on what a website costs. And if you are still wondering why you need a website and not just a social media page, start there.

How we start

We ask you three things: which invoicing program you use (or want to use), whether you sell to individuals, companies or both, and how many orders you get a day. From the answers we know exactly which module or API to wire in.

We build you a free demo site, with the order flow set up, so you can see for yourself how an order turns itself into an invoice and an e-Factura. Write to us on WhatsApp: wa.me/40750257140.
