Invoicing automation: how to get started? Automate your tools

What is an automated invoicing process and what does it look like?

Simply put, invoice automation is about streamlining various stages of document management – from pulling data from company systems to issuing invoices and handling them thereafter. This means an invoice can be generated automatically based on pre-approved information, such as an order, quote, or transaction status, without having to re-enter the same data in multiple places.

It is worth remembering, however, that the invoicing process does not end with issuing the document. Receiving invoices from contractors, cataloging them, assigning them to the right people, and archiving them are just as important. Below is an example of an invoice archiving automation workflow, showing one of the possible components of such a process.

Issuing accounting documents – what should you optimize?

In many companies, accounting departments still operate as if time has stood still – managers hire more assistants to re-enter data, manually create invoices, print paper documents, or track payment statuses. But why, when these processes can be successfully automated? Below are 3 key areas worth automating in SMEs.

Data acquisition – integration with software and source documents

Do your employees spend every month searching through dozens of tools, spreadsheets, and communication channels to find all the client agreements, hours worked, or service prices that need to be invoiced? Thanks to invoice automation, manual searching and data entry into accounting documents is a thing of the past! An invoicing system can automatically pull data from your CRM, ERP, or order documents (or your e-commerce platform if you are a seller), so the invoice is created based on pre-approved data, which eliminates errors and saves time.

Business logic and payment data processing

Invoice automation allows you to apply predefined rules: for example, company-specific discount calculations, assigning the correct VAT rates, or selecting invoice templates based on the client type. Various types of automatic validations are also possible: does the contractor have a valid tax ID? Do the terms match the contract? As a result, accounting processes no longer rely on manually analyzing every invoice – all conditions are checked and enforced according to established rules.

Automatic invoice generation in response to specific events

Automation can generate structured XML invoices with automatic numbering and a full set of data required by law and your company procedures. Additionally, it is possible to automatically search for and attach documents (e.g., specifications, delivery notes, contracts). One of the most significant benefits of invoice automation is that the document can be created in the background and without manual intervention. Define which event should trigger the invoicing process, and accounting documents will be automatically generated as a result of order approval, service completion, or a change in transaction status within your CRM. Thanks to this integration, you not only save time by eliminating manual document creation, but you also significantly reduce the workload on your accounting department. No one needs to remember to issue invoices or track deadlines. Invoices are created exactly when they should be – as a natural part of the business process – rather than as a separate, manually triggered task.

Automated invoicing and other business processes

In practice, issuing the invoice itself is not the biggest challenge – after all, it is just the final result of a whole series of actions. Our experience shows that the problem starts earlier: with a lack of consistency between departments, delayed information flow from sales representatives, incomplete data from the operations department, or the need for manual transaction confirmation. Therefore, we will most likely see the benefits of automating the invoice accounting process when we approach the problem holistically.

How to effectively implement invoice process automation?

Below are 4 simple steps to successfully implement invoice automation in the SME sector:

1. Understand that the invoicing process does not start in accounting

An invoice is the result of actions taken by many departments—sales, logistics, and customer service. Check where invoice data originates and which activities influence it before it reaches the accounting department.

2. Identify invoice touchpoints

Determine who enters the data, where errors occur most frequently, and what blocks the smooth flow of information. That is where improvements will have the greatest impact.

3. Define rules and exceptions for invoice processing

Define the conditions that must be met for an invoice to be generated automatically. Consider different transaction models, deadlines, currencies, or unusual scenarios.

4. Choose the right software that integrates with other departments

Automated invoicing must be part of a larger ecosystem—such an improvement should pull data from your CRM, ERP, or order management system and forward invoices to the customer, bank, or external accounting department. That is why off-the-shelf solutions and tools that treat invoice automation as a standalone process do not always work.

One of our clients encountered a problem while using Comarch ERP Optima. The tool did not allow for invoices to be automatically sent to more than one email address. Employees could only send the invoice to the customer, but their workflow and billing requirements also necessitated sending copies to a purchasing department representative and a sales representative. Implementing a custom invoice automation process saved our client dozens of hours each month. This example shows that off-the-shelf systems do not always meet every business need—sometimes it is necessary to implement additional solutions or extensions. In the case of automated invoice delivery for our client, only a custom integration allowed them to achieve full process efficiency.

Real-world invoice automation examples – discover the benefits of automating our clients' processes

If we still haven't convinced you that investing in invoice automation is truly worth it, take a look at the following client implementations and learn how BPA (Business Process Automation) can help you. Note: these aren't your standard case studies about automating processes within invoicing software – that’s not why you opened this article. The examples below involve more complex problems that will show you how significantly other company processes impact invoice processing.

Invoice automation in a trading company

Our client's challenge:
A trading company was struggling with inefficient invoicing after sales were completed. Sales representatives would fill out an invoice data form in dedicated software and then manually attach an acceptance protocol. This form served as the basis for the accounting department to create and send invoices. The problem was that, due to errors, the data in the form often didn't match the original order or the content of the protocol. This led to numerous misunderstandings and email exchanges between sales and accounting – every invoice required manual verification, data correction, and re-confirmation. The process was tedious, error-prone, and frustrating for both sides.

Our proposed solution:
We redesigned the entire process so that sales reps no longer have to perform two separate tasks: filling out a form and attaching a protocol. Instead, they now fill out a single, simplified online form that contains all necessary data, with built-in validation (e.g., order consistency, item completeness, customer data accuracy). Once submitted, the system automatically generates a sales document, which is emailed to the rep for an electronic signature. This document replaces the previous manually created protocol and serves as the basis for issuing the invoice – without any extra emails, files, or back-and-forth with accounting.

The effect of accounting automation:
Thanks to automatic invoice generation, the process was shortened from several days to just a few minutes. The accounting department now receives only complete and verified data, and the number of errors and "manual corrections" has dropped to almost zero. Sales reps have gained a clear workflow, and the company now has a smooth, scalable, and automated sales document management system.

As you can see, the mere fact that an invoicing program has an automation module isn't always the solution; sometimes you need to look at a problem more holistically, calculate the risk of human error, and rework parts of the tasks performed by your team.

Implementing KSeF automation

Our client's challenge:
The client approached us looking for a solution that would allow them to efficiently handle KSeF (Polish national accounting system) without abandoning their existing SAP system. Sales invoices were prepared in SAP and then exported and sent to customers. The problem was that the company's headquarters would not agree to move away from SAP or transfer invoice handling to another program with native KSeF integration. The client needed a tool that would bridge their current workflow with KSeF requirements while also streamlining purchase invoice management by routing them to the appropriate people in the organization.

Our proposed solution:
We proposed a solution that pulls data from Excel files generated in SAP and converts them into a KSeF-compliant format, accounting for various invoice types, corrections, and additional fields required by the client. The system validates data, detects errors and duplicates, allows for correcting specific items without reloading the entire file, and logs the history of operations and statuses. We also handled the KSeF integration via an authorization token, retrieving KSeF numbers after submission, generating PDFs with QR codes, and enabling bulk document downloads. Additionally, we designed a user and permissions panel so that invoices can be routed to the right people based on their role or tax ID (NIP).

This project shows how KSeF integration can be implemented in various ways — not just through off-the-shelf invoicing software, but also through solutions tailored to a company's existing system environment. In many organizations, the key is not to replace the current tool, but to build an integration layer that connects KSeF with already functioning systems, business rules, and document workflows.

Automating accounting for a steel products distributor

Our client's challenge:
At a company selling steel products, the sales process was fragmented, relying on manual tasks and time-consuming verifications. The accounting team had to check customer data across multiple systems (CRM and ERP), manually verify tax IDs, transcribe information from phone calls, and build quotes by hand—assigning the correct code to every single product. Once a quote was sent, an email exchange with the client would follow, often involving negotiations on prices and terms. To offer the right discount, sales reps had to manually review the customer's order history. After the quote was accepted, staff would manually issue the invoice.

Our proposed solution:
We implemented automation covering the entire process—from the first customer contact to invoice creation. Sales calls are now automatically recorded, and the system uses transcriptions to create auto-notes, which are stored in the database and serve as the basis for generating a quote (cost estimate). The system automatically selects product items, codes, prices, and discounts via API, taking the customer's purchase history into account. As a result, the sales rep receives a ready-to-use draft quote that they can approve or edit and then send to the client without having to manually fill out files. Once the client accepts the quote, the data is automatically pushed to the software, where a final invoice is generated based on the approved estimate—eliminating the need for manual data entry, extra emails, or additional verification.

The impact of automating the accounting department's work:
The time required to prepare a quote has been reduced from tens of minutes to just a few, and invoices can be issued almost immediately after a quote is accepted—without any intervention from the sales team. The team no longer has to manually transcribe data from files, and the invoicing process is now free from errors and delays.

This example perfectly illustrates that the problem often lies not in the act of issuing an invoice itself, but in what happens beforehand. Before a document reaches the accounting department, employees must gather data from various sources, confirm terms, and verify consistency with the quote—and it is these document management tasks that prove to be the most time-consuming and error-prone.

What are the benefits of properly implemented invoice automation?

Properly implemented invoice automation allows a company to reclaim time previously spent on re-entering data, searching for documents, and resolving discrepancies between departments. Thanks to a consistent invoice workflow, it is easier to maintain control over statuses, payment deadlines, attachments, and the individuals responsible for each stage. The company reduces the number of errors, speeds up the work of the finance department, and gains greater predictability across the entire sales and settlement process. Importantly, a well-designed solution does not have to mean replacing all existing tools—often, it is enough to connect them into one efficient ecosystem.

As a result, invoicing ceases to be a separate, burdensome task and becomes a natural part of the company's daily operations.
