What does invoicing software do?
Invoicing software keeps your customer details, products and invoices together. Select a customer, enter the products or services you supplied and create an invoice to send. When another project comes along, reuse the information you saved. That means less copying of old documents, retyping amounts and keeping track of separate files for each customer.
Factuur Simpel is for freelancers and small businesses in the Netherlands and Belgium who send their own invoices and quotes and leave the bookkeeping to their accountant. It is the step up from Word or Excel: customers, products and invoices in one place, with the next invoice number and your logo added automatically. The app works in English; invoice PDFs use Dutch labels and euros. If you want to do your own bookkeeping or need recurring invoices or several users, accounting software is a better fit.
From customer details to a sent invoice
Set up your business and branding
Enter your business details and add your logo and background. Save customers and the products or services you use often. For example, store a description of your usual service as a product. When you create the next invoice, reuse those details and adjust them to match the work you completed.
Turn your work into a clear invoice
Select your customer and add the products or services you delivered, with quantities, prices and the applicable VAT rate. Factuur Simpel calculates the amounts for you. The invoice shows your customer what the work covers and how the total is made up. Review the details and it is ready to send.
Send it and keep track
Send the invoice by email, or use Peppol when your business is connected and your customer can receive invoices through the network. Find your invoices in your account and keep track of outstanding payments. If a customer asks about a particular invoice later, you can return to it without searching through separate documents.
Features for day-to-day invoicing
The features you will use most in day-to-day invoicing.
Invoices in your own branding
Upload your logo and background once and every invoice and quote gets the same professional layout. Branding, customer management and product management are included in every plan.
VAT calculated automatically
Enter quantities, prices and the VAT rate; Factuur Simpel works out the lines and totals. Complete also gives you a VAT overview to prepare your return.
Online payment through a payment link
Connect your Mollie account in Complete and add a payment link to your invoices. Customers pay online without retyping details. Mollie charges its own transaction fees.
Invoice from your phone
Create an invoice right after the job in the iOS or Android app and continue in the web app at your desk. Everything lives in the same account, also with Starter.
From quote to invoice
Create a quote with the same customers and products as your invoices. Once your customer agrees, convert the quote into an invoice and every line comes along automatically.
Expenses and receipts in one place
Keep receipts and expenses next to your invoices so your records are complete. Export everything when your accountant asks. Unlimited, in every plan.
Required invoice details, filled in for you
Tax rules set out what an invoice must show, such as your VAT number, a unique sequential invoice number and the VAT per rate. Our guide lists the required details and the exceptions.

How Factuur Simpel helps
Your business and customer details appear on every invoice automatically. Each new invoice gets the next number in your sequence and VAT is calculated per line. You only fill in what you delivered.
Send and receive e-invoices through Peppol
Send and receive structured e-invoices from your own account. With Peppol in Complete, invoice data reaches the software used by connected customers. Keep the exchange of invoices in one place for both sides. Connect your business to the network and manage regular invoices and Peppol invoices in the same account.

Invoicing software or accounting software?
Accounting software handles your entire administration, from bank transactions to tax returns. Invoicing software focuses on the work you do every week: quotes, invoices, customers and expenses. Factuur Simpel is deliberately invoicing software. You see what you have invoiced and what is still unpaid, without bookkeeping knowledge.
Working with an accountant? Then there is no need to pay for an accounting module you won't use. Export your invoices and receipts and hand them over. With Complete you also have a VAT overview at hand when your return is due.

Frequently asked questions about invoicing software

How is it different from invoicing in Word or Excel?
In Word or Excel, you keep track of invoice numbers, VAT calculations and storage yourself. In Factuur Simpel you select a saved customer and product, each invoice gets the next number automatically and VAT is calculated per rate. Previous invoices stay in the same account.
Is Peppol included in every plan?
Peppol is included in Complete. Once your business is connected, you can send and receive structured e-invoices through the network. Starter covers the essentials of invoicing and quotes; choose Complete when you need Peppol.
Can I create invoices on my phone?
Yes. Factuur Simpel has apps for iOS and Android alongside the web app. The mobile app is available with Starter and Complete. Use your account to work on your invoices when you are away from your desk.
Can I share invoices and receipts with my accountant?
Yes. Export your invoices and receipts to send them to your accountant or keep them in your own archive. Exports are included in both Starter and Complete.
Can I create quotes and turn them into invoices?

Can I cancel my subscription at any time?
Yes, Factuur Simpel can be cancelled any day. Your subscription stays active until the end of the period you have already paid for. Until then, export your invoices and expenses to Excel or PDF and your customers to Excel or CSV, so you can take everything with you.
Can I track expenses and receipts too?
Yes. Upload receipts and record expenses next to your invoices, unlimited and in every plan. With Complete, uploaded receipts are processed automatically.
