How to Automate WooCommerce Invoices with Holded

If you manage a WooCommerce store, invoicing is one of those tasks that doesn’t add value to the customer but steals hours from you every week: downloading orders, creating the invoice in Holded, sending it by email, and resending it when someone loses it. As the volume grows, the manual process becomes unsustainable. In this guide, you’ll see How to Automate WooCommerce Holded Invoices so that invoices generate themselves, payments are recorded in the correct bank, and your customers download their documents without contacting you.

How to Automate WooCommerce Holded Invoices

WooCommerce manages orders well, but it is not an invoicing program. The typical flow without integration is this:

  1. An order comes into the store.
  2. You copy the customer’s data (with their NIF, if provided) to Holded.
  3. You create the invoice line by line, with discounts, shipping, and VAT.
  4. You manually send it to the customer.
  5. You record the payment in your bank within Holded.
  6. If there is a refund, you manually create the corrective invoice.
  7. If the customer loses the invoice, they write to you again, and you resend it.

Each step is an opportunity for error and, above all, a waste of time. Multiply it by dozens or hundreds of orders per month, and you’ll understand why so many stores seek to automate it.

Why Choose Holded as an Invoicing System

Holded is one of the most used ERPs by SMEs and freelancers in Spain: it centralizes invoicing, accounting, treasury, and inventory, and is aligned with the requirements of Spanish electronic invoicing. The challenge is not Holded itself, but connecting it with your WooCommerce store so they stop being two separate worlds that you sync manually.

What a Good Holded-WooCommerce Integration Should Do

Not all integrations are the same. A generic connector (like Zapier or Make) can copy the order to Holded, but falls short on the important stuff. A complete integration should cover the entire cycle:

  • Automatic invoice or ticket at the moment you decide (order completed or processing), with official Holded numbering.
  • Exact amounts: coupons and discounts per line, shipping costs, and charges with the correct VAT. If the invoice doesn’t match the order to the cent, the integration is useless.
  • Automatic credit notes when you refund an order, fully or partially.
  • Synchronized customers with their fiscal address and NIF/CIF.
  • Payments recorded in the correct bank: what is collected by Redsys to one account, PayPal to another. This way, bank reconciliation is automatic.
  • Synchronized stock: each sale deducts inventory in Holded and each return restores it.
  • Customer portal: each buyer downloads their invoices in PDF from your website, without requesting them by email.

Step-by-Step Guide

With the EHERO Woo Holded plugin, the entire process will take you less than 10 minutes:

1. Install the Plugin

Upload it from Plugins → Add New → Upload Plugin, like any other WordPress plugin, and activate it.

2. Connect Your Holded API Key

In Holded, go to Settings → Developers → API and generate a key. Paste it in the plugin settings. You don’t need anything else to start.

3. Enable Automatic Invoicing

Choose the document type (invoice or ticket), the creation moment (order completed or processing), and if you want automatic approval and email sending from Holded. From then on, each new order generates its invoice without intervention.

4. Configure the Rest at Your Own Pace

When needed, activate the rest of the automations: credit notes on refunds, payment registration with a different bank per gateway, stock control by SKU, and massive synchronization of historical orders to invoice what was sold before installing the plugin.

Invoice Portal for Your Customers

One of the most appreciated improvements is not for you, but for your customers: within their WooCommerce account, they will see a section with all their invoices, corrective invoices, quotes, proformas, and delivery notes, with a filter by year and instant PDF download. Each customer sees only their documents.

The effect on the day-to-day: you stop receiving emails like “Can you resend the March invoice?” and your store gains a professional image.

What to Consider for Security

When connecting two systems with fiscal data, security matters. Ensure that the integration:

  • Does not expose your API keys to the browser. In EHERO Woo Holded, PDF downloads go through a secure proxy: your key never leaves the server.
  • Restricts access so that each customer only sees their own documents.
  • Logs activity: a synchronization log tells you what was created, when, and if there was any issue.

Benefits for Your Business and Customers

For your business:

  • You save hours of invoicing and reconciling payments manually.
  • Your Holded inventory reflects online sales in real-time.
  • You reduce errors: amounts come from the actual order, cent by cent.
  • You project a professional image with a portal integrated into your own website.

For your customers:

  • Access to their invoices at any time and from mobile.
  • Search by year and document type.
  • Instant PDF download.
