E-invoicing for Small and Medium Businesses (SMEs)

Link4 helps firms like yours grow and profit by future-proofing your business!

Why is Link4 Right for your Business?

Save time and money
E-invoicing reduces the need for manual data entry which in turn reduces the costs of invoice processing up to 80%! Invoices are delivered straight into your Cloud Accounting system, saving the time your staff spends on handling or following up on invoices.
Efficient and convenient
E-invoicing helps streamline your procurement process. You don't have to worry about invoice duplications and errors, which improves the overall productivity of your staff.
Improved cash flow
E-invoicing eliminates payment delays. With Link4, invoices land directly into your customers’ Accounting system, which simplifies the approval process. Consequently, invoices are paid faster or on time, improving your cash flow.
Safe and secure
As a Peppol accredited service provider, with Link4 your information will be safely delivered to your trading partners through the Peppol E-invoicing network. We ensure that neither party would fall victim to any form of email scams - including payment redirection scams which have caused and continue to cause many SMEs considerable damage.
High-security document storage
You can feel confident in securely accessing your e-invoices from anywhere. With all your invoices stored in the cloud, you will never lose an invoice again or risk any external party getting access either. What's more, Link4 assures all information shared will remain confidential and we are granted limited access to accounts, bills, and contacts to ensure a more trusting experience.

It is a real time saver for me not to have to enter invoices. All I do is a double check when a Statement comes in, so easy.

Definition of “transaction” in e-invoicing:

The act of either sending an e-invoice to your customer or receiving an e-invoice from your supplier. This means if you would like to both send and receive e-invoices, each instance of sending or receiving an e-invoice is counted as a single transaction.
