Smart Invoicing

March 5, 2026

The cornerstone of the Accai invoicing and accounting system is the intelligent creation of all types of documents in user-friendly designs that you may need for your business activities.

You can easily create not only invoices, but also quotes, advance invoices, tax documents for received payments, and, if necessary, credit memos and cancellations. It’s entirely up to you whether you create all of these documents or just some of them.

Using Accai will simplify and speed up the entire sales process.

From the moment a client expresses interest in your product or service, through the establishment of a business relationship, to the completion of the sale or delivery of the service—and, in the case of less responsible clients, all the way to issuing a reminder for an unpaid invoice. 

In addition, Accai will always assist you with preparing documents and guide you so that you don't overlook any legal obligations.

Automatic Data Entry on Documents

The most commonly used feature when creating invoices is the automatic completion of customer information based on the entered company ID or business name. In other words, simply enter the company ID, and all the information about that customer will be populated automatically.

Another practical feature is the automatic filling in of data in documents (e.g., description, item number, delivery type, payment method, and delivery method) from the “company settings” that you specify in your company’s settings. If you save a customer as a client, you can assign them their own specific settings, which will also be automatically filled in on invoices. This way, you can have different invoice descriptions for different clients, for example, without having to enter them manually.

Since individual documents are linked to one another, they can automatically use data that has already been entered, allowing you to create a new document from an existing one in just a few seconds. You don’t have to create a new document every time; instead, you can easily create a follow-up document from an existing one. For example, you can use a pro forma invoice to issue a payment receipt or a final invoice. You can copy individual documents and update them with any necessary changes.

VAT Regime, Exchange Rates, and Foreign Currencies

Accai automatically selects the correct VAT regime on documents based on the customer, which reduces the risk of incorrectly issued tax documents. You can also invoice in foreign currencies, and thanks to its integration with the NBS exchange rate list, Accai will automatically apply the correct exchange rate in accordance with the law. Of course, you can also choose the document’s language, for example, if you have international clients.

QR Codes on Invoices

One of the most highly valued features is the ability to pay invoices using a QR code. Invoices issued through the Accai online invoicing system include a generated QR code, allowing clients to pay their invoices quickly and easily using a smartphone. There are many advantages to QR code payments, ranging from faster invoice payments—which automatically improve your cash flow—to a lower error rate, leading to a higher payment-matching rate. This saves your accountant time and inevitably results in lower accounting costs.

Use of Number Series on Invoices

To improve document identification and clarity, Accai offers the "Number Series" feature. Number series are used to distinguish one type of document from another (for example, invoices issued for services and invoices issued for the delivery of goods). You can use the default number series or create and use your own number series. The invoice will automatically be assigned the next number.

Automated Matching of Payments with Issued Invoices

By using Accai’s open banking services in a secure manner, you can access real-time transactions in your bank account. Recorded payments are immediately and automatically matched with received and issued invoices, or with other documents as needed. This gives you a real-time overview at any time of which invoices have been paid and which are still outstanding.

Automatic Invoice Posting

The Accai accounting system will immediately post the invoices you issue. If your business partner also uses Accai, the document will be automatically posted in your system as well once you authorize it. This means you no longer have to worry about repeatedly forwarding these documents to your accountant. Artificial intelligence will take care of posting the rest of the received invoices and other documents.

E-invoice

When developing our online invoicing tool, Accai, we had already anticipated the upcoming e-invoicing system. The e-invoicing system, which is being prepared by the Ministry of Finance, is scheduled to take effect in January 2023. Simply put, invoices will be uploaded and sent in real time to the tax authority. Every invoice issued by a business owner will be visible to the government—even before it is sent to the customer. E-invoicing could simplify administrative tasks for business owners and help the government detect tax fraud.

Accai invoicing tool included in the free basic package

As the saying goes, it’s better to see something once than to read about it a hundred times. That’s why we offer our Accai invoicing system for free in the Basic Plan. With this plan, you can create both final and pro forma invoices featuring your logo for an unlimited number of your customers. All other benefits and features that Accai offers are clearly organized and priced in our Price List.

We look forward to working with you.
