6 tips to maximise efficiency with invoice processing and automation

Automating your invoicing process means one thing — efficiency. And efficiency breeds productivity, which puts you in a great position to remain competitive in your industry. More time for thinking, planning, forecasting, and budgeting. And best of all? It rids these important processes of human errors.

What is automated invoice processing?

Invoice processing automation is where large parts of the accounts payable process are streamlined through automation. Improving expense data accuracy, reducing fraudulent expense claims and speeding up the entire process.

Meanwhile, automated three-way matching tech flags if there are discrepancies between receipt notes, purchase orders, and invoices. Data is automatically extracted and categorised, and automated approval workflows ensure every invoice follows the proper sign-off process in a prompt manner.

The alternative? A manual accounts payable process which is long, drawn out, and majorly lacking efficiency.

The top six ways that automating invoice processes maximise efficiency

Automating invoice processes isn’t new exactly — there are plenty of tools out there, from Payhawk to Airwallex, promising to make invoice handling easier. But not all automation is equal (and that’s before we even get to AI). The best solutions don’t just digitise invoices; they transform how your finance team works.

Here’s what to look for when choosing the right one.

1. It reduces manual errors and enhances accuracy

Inaccurate data can delay invoice payment and processing, which means more time spent correcting sloppy mistakes. By automating the process of invoice data collection with OCR technology, you can always rest assured that your data is accurate.

2. Streamlines workflows to save time

By ridding your processes of repetitive manual data entry, you boost efficiency across the organisation. No longer are you delayed by human processes. Think automatic, real-time reconciliation — where payment data flows seamlessly between your solution and your chosen ERP or accounting software.

Just as crucial are the approval workflows themselves. Instead of relying on scattered chats, forms, or in-person signoffs, automated workflows ensure every invoice follows a clear approval path — making the process faster, more reliable, and significantly reducing the risk of unauthorised payments or fraud.

And to make things even easier, Payhawk can automatically populate expense field data, reducing manual input and errors while streamlining how spend is classified, coded, and approved.

AI takes this one step further. Instead of your team manually chasing missing data or approvals, the Financial Controller Agent proactively follows up in Slack, Microsoft Teams, or within Payhawk — closing the loop faster and freeing up your team’s time.

3. Automatically matches purchase orders and invoices, so you don't have to

Payhawk’s automatic 2- or 3-way matching compares purchase orders, goods received, and invoices to flag mismatches. This ensures you only pay for what was ordered and delivered, helping avoid overpayments and fraud. It also frees up your finance team from manual checks, speeding up approvals.

Combined with the Procurement Agent, every purchase request, approval, and PO is automatically orchestrated from the start, making matching faster and more reliable. POs can even be auto-generated and linked to invoices and GRNs without manual setup.”

4. Improves cash flow visibility and management for informed spending decisions

Knowing who’s spending company funds, what they spend on and additional spend you've committed to helps you forecast cash flow more accurately. After all, if you don't know what money you have coming in and out, you can't plan for future growth.

5. Provides real-time visibility to budget holders

With invoice automation that’s natively connected to budgets, you get more than just process efficiency — you gain real-time budget visibility as spend happens, not after the fact. Unlike standalone budgeting tools, Payhawk lets you track budget utilisation the moment an invoice is submitted or approved, so you can stay in control and avoid surprises later on.

And because AI Agents operate across procurement, travel, and payments, budget holders can see every committed or planned expense the moment it’s requested. No need to wait for post-approval data — you get continuous budget visibility across departments.

6. Enables collaboration between departments to keep comms tidy

Cross-department collaboration is important when managing company finances. And if you're currently relying on other apps to communicate (like emails, or Slack), your processes are fragmented, meaning notifications or messages can get lost easily. Keep processes as efficient as possible and avoid bottlenecks with in-platform comments. Tag relevant parties and receive all notifications in your Payhawk inbox. You'll never have to chase through email again.

How to choose the best automated invoice processing software

Deciding which software is the best for your business takes some careful research. You don’t just want a great product; you need a user-centric product to ensure high adoption — something that’s going to add extreme value to your business.

Identify the best software for invoice automation

Before signing on the dotted line, you’ll need to weigh up your options. There are plenty of automated invoice processing solutions available on the market, but you must ensure they can help you achieve your wider business goals.

Adrià Vázquez, CFO at VICIO, explains:

With the tool we used before, we felt blind about certain information. I didn't know where to make adjustments and couldn't find things out fast enough. Now, with Payhawk, we can maintain visibility and control over spend, even as the number of receipts and invoices multiplies. And Payhawk's traceability empowers us to invest our cash where it will generate the greatest profitability.

First, sit down and figure out what you need vs want. Your solution should tick every single ‘need’ box and most (if not all) of your ‘want’ boxes, too. What features do you need to improve efficiency? Perhaps a mobile app for employees to submit expense reports? Or maybe you’d like the functionality to build complex approval workflows? Check that your preferred providers offer what you need or at least has them on the roadmap.

Test all relevant products on the market. That means taking advantage of product demos and seeing in real-time how the product works, and which features you can make good use of. You need software that’s easy to use, of course, but also effortlessly scalable — a product that can grow and change with your needs.

Consider integrations. The solution should have advanced integration capabilities to help unify your tech stack and synchronise your financial data — a solution that screams efficiency and shuns fragmented data.

This is one of Payhawk’s strongest suits: with deep, reliable ERP integrations, you avoid the manual work that often falls on senior finance staff. Poor integrations can eat up valuable time and require expert intervention to fix errors — the right solution should minimise manual effort and seamlessly fit into your existing systems.

Implement best practices for a smooth transition to automation

You can become so focused on finding the right solution that you forget about implementing it as effectively as possible. That means educating your staff on new spending policies, creating the policies in the first place, and setting training in motion to ensure high user adoption and an efficient transition period.

Most invoice automation software comes with some kind of training, but it’s worth clarifying what exactly. Don’t assume the activation teams will equip you with everything you possibly need. Check out the system’s support section and customer service accessibility.

And don’t forget to check in to see how the transition is going. Monitor performance metrics and implement changes for continuous improvement.

Enhance data accuracy with intelligent document processing

It takes roughly about 10 minutes to process a single invoice, from printing it out, manually transferring across the document data, searching for the purchase order, and checking invoice details match before emailing the person who needs to approve the invoice payment.

Research suggests the average AP clerk processes around 1,000 invoices per month. Imagine all that time you can’t get back.

Aside from the time you’re wasting doing these manual processes, you’re increasing the chances of clumsy errors. All it takes is rushing some data input or getting distracted mid-entry, and your data becomes skewed. These mistakes mean data is inaccurate, leading to delays in invoice payments, and inaccurate financial reporting means cashflow forecasting and budgeting are incorrect.

But using AI and machine learning built into automated invoice processing tools means your processes are streamlined and error-free. By setting up validation processes through Payhawk, you ensure data integrity, always, and by utilising OCR technology in your invoice processes, data extraction makes the process so much more convenient and efficient for everyone involved.

Create efficient approval workflows for faster processing

Every organisation has different needs when it comes to approving invoices. You might want to automatically route them by department, budget, or amount. With Payhawk, you can create complex conditions when routing invoices using parameters such as category, amount, or custom fields.

This level of flexibility means your approval process mirrors your exact organisational structure — not the other way around. Whether you’re routing marketing invoices to department heads, flagging large purchases for CFO review, or separating internal and external vendors, every request follows a clear, visible path. Nothing slips through the cracks.

And because the Payhawk workflow designer is completely no-code, anyone can build and update workflows without needing IT support. Finance teams can adjust approval routes in minutes, keeping processes agile as your business scales or your policies evolve.

Pair that with Payhawk’s AI-powered automation, and you get the best of both worlds — structured workflows that run on your rules, and intelligent agents that chase, check, and close out tasks automatically.

Daniel Tang, Finance Manager at PinPoint Media, says:

Payhawk’s workflow designer has improved the overall ease of use by being very intuitive. It has also improved the customisation functionality, as we can modify the workflows depending on the project department.

Make compliance and security a priority

You must comply with local regulations — GDPR in some countries or CEN standard EN 16931 (“the European Core Invoice standard”) for electronic invoice processing, for example. So, when automating invoice processing, you must find a solution that keeps your data compliant and secure.

Find a solution that is serious about implementing data security measures. Look out for:

• Industry-standard AES-256 encryption of data in rest and transit
• PCI DSS compliance
• Threat detection to help you identify unauthorised or malicious activity
• Access control, including two-factor authentication and multi-factor authentication
• Automatic fraud detection
• Compliance management

Please note that Payhawk has all the above and more.

Integrate invoice automation with existing business systems

There’s no point introducing a new piece of software if it doesn’t mould into your existing tech stack. You don’t want to introduce another password for employees to remember. But suppose the tech integrates seamlessly with other systems like your ERP and accounting systems. In that case, you’re unifying data, closing comms gaps (facilitating data exchange between departments) and accessing real-time reconciliations.

Jan-Willem Gmelig Meyling, CFO & CTO at AthenaStudies, describes:

Payhawk not only books the payment overview, but also the purchases in Exact Online. The purchases also contain the uploaded invoice as an attachment. As a result, everything is in Exact, and the financial administration or accountant does not have to search in multiple systems.

Automation is key in invoice processing

As a finance leader, there are many ways for you to drive digital transformation in your organisation. And one of the most impactful ways to do this is to embrace automation.

Mathias Goetz, Senior Project Manager at ATU, says:

Digital transformation is an important challenge for us. A couple of years ago, we used to transport our paper invoices through Germany with two of our trucks. When buying parts from other companies in the sector, our branch managers (over 500) would historically always reach for cash, generating a massive amount of paperwork. With Payhawk, we have a solution that lets us streamline processes and save on overhead costs.

Automation saves time, helps cut costs, and gives you accurate financial reporting in the palm of your hand. Equipped with all this newfound visibility, you have the power to drive real organisational change, from resource allocation to prompt (and accurate) supplier invoice payments.
