Overview
AON Solutions develops management software for accounting firms and professional services businesses, helping them manage accounting, tax and payroll processes from a single platform.
As a technology provider focused on the accounting industry, AON Solutions works closely with firms that must handle growing volumes of invoices while meeting increasingly demanding reporting and tax deadlines.
As these firms grow, so does the amount of documentation they need to review and process. While invoice processing is essential to maintaining service quality, it is also one of the most repetitive and time-consuming tasks within an accounting practice.
To help its customers scale without proportionally increasing operational workload, AON Solutions partnered with Invofox to automate invoice processing.
Today, Invofox helps process more than 450,000 invoices every year for brands such as Ayuda T Pymes and Infoautónomos, allowing accounting professionals to spend more time on high-value advisory work and less time on administrative tasks.
When manual work stops scaling
Invoice processing is part of the daily reality of every accounting firm.
Before adopting Invofox, many AON Solutions customers still relied heavily on manual processes to review and bookkeep invoices. This not only consumed a significant amount of time but also increased the likelihood of mistakes when teams were working under pressure.
According to Manuel R.P., a member of AON Solutions' onboarding team and an accountant himself, the challenge was never a lack of expertise. It was simply the volume of work that professionals were expected to manage.
Sooner or later, a mistake slips through. Not because people aren't capable, but simply because of the amount of manual work involved.
When discrepancies appeared, teams often had to review documents one by one until they found the source of the issue. This created frustration for both accounting firms and support teams.
Until we found the error, nobody could relax.
During critical periods such as tax filings and reporting deadlines, this situation could quickly become a constant source of pressure.
Sticking to what you do best
AON Solutions already had its own OCR capabilities. However, the company made a strategic decision not to invest resources in an area outside its core expertise.
Rather than dedicating time and effort to building and maintaining document automation technology internally, AON Solutions chose to focus on what it does best: developing management software for accounting firms.
For document automation, the company looked for a specialist partner capable of delivering accuracy, scalability and continuous improvement.
We preferred to leave document automation to those who truly specialize in it and focus our efforts on what we do best.
This decision allowed AON Solutions to offer advanced automation capabilities without diverting resources away from its core product roadmap.
The philosophy behind this approach was straightforward:
It's a tool that helps you do your job. It doesn't do your job for you.
Automation removes repetitive work, but professional judgment remains firmly in the hands of the accountant.
More time for advisory work
After several years using Invofox, AON Solutions has identified three key benefits: time savings, accuracy above 90%, and a significant reduction in the number of errors requiring manual review.
Each employee saves between five and fifteen hours every week that would otherwise be spent reviewing and processing invoices manually.
That time can be redirected toward activities that create more value for clients, from answering questions to providing strategic guidance and support.
It's time you can dedicate to what you really enjoy and what made you become an accountant in the first place: advising clients.
Automation also allows professionals to focus only on the documents that actually require attention instead of reviewing every invoice that enters the system.
With more than 450,000 invoices processed annually and accuracy exceeding 90%, teams can spend less time on repetitive administrative work and more time helping their clients succeed.
Less stress, more confidence
Beyond the efficiency gains, one of the most valued benefits has been the operational confidence automation brings.
Knowing that every invoice goes through an additional automated validation layer significantly reduces the risk of errors and gives teams greater confidence during peak workload periods.
This helps reduce discrepancies, minimize unnecessary reviews and maintain quality standards even during the busiest times of the year.
For professionals working under constant deadline pressure, that confidence translates into a better experience for both advisors and their clients.
A long-term partnership
For AON Solutions, the value of Invofox extends beyond the technology itself.
The company particularly highlights the responsiveness of the team, the close working relationship and the ability to adapt quickly whenever new requirements arise.
The experience has been very positive. The relationship has been close and solution-oriented.
Especially during critical periods such as tax deadlines and reporting cycles, having a responsive and accessible partner has been a significant advantage.
The response has always been fast and helpful, which is exactly what you value when you're working against deadlines.
Looking ahead
For AON Solutions, document automation has become a key component in helping accounting firms grow without proportionally increasing operational complexity.
As document volumes continue to rise, the combination of automation and professional expertise will remain essential for delivering efficient, high-quality service.
By reducing repetitive work and administrative effort, accounting professionals can spend more time where they create the greatest value: supporting clients, solving complex challenges and helping businesses make better decisions.
