From Local Server Room to Global Cloud
How abcgo.pl Reduced Costs by 40% and Secured Client Financial Data.
Executive Summary
Accounting offices operate on the "living organism" of their clients' businesses. For abcgo.pl, serving hundreds of entities, every minute of downtime in the enova365 system or a data leak poses a risk of reputational loss. Professnet executed a comprehensive migration to Microsoft Azure, transforming traditional IT into a modern, scalable work environment. The result? Systems run faster, data is more secure than in a bank, and maintenance costs have dropped by nearly half thanks to FinOps engineering.
Challenge: "Bottleneck" During Tax Season
Before the migration, abcgo.pl struggled with problems typical of dynamically growing accounting firms using On-Premise infrastructure (their own servers):
enova365 System Performance
During settlement periods (the 20th of the month, year-end closing), the load on the SQL database increased drastically. Local servers would "choke," causing slowdowns in accountants' work.
Remote Work Risk
Employees connecting via VPN to the office represented a potential security gap. There was a risk that sensitive files (JPK, declarations) could be downloaded onto private laptops.
Cost Rigidity
The company had to maintain expensive infrastructure that went underutilized for most of the month, just to handle the "tax peak."
Security & Compliance
Growing GDPR and ISO 27001 requirements enforced security standards (encryption, access logging) that were difficult and costly to implement on old hardware.
Solution: Tailor-Made Architecture (Azure Well-Architected Framework)
Instead of a simple server replacement (Lift & Shift), Professnet designed the environment from scratch, basing it on the five pillars of the Azure Well-Architected Framework.

Core Business Optimization (enova365 & SQL)
We migrated the heart of the company, the enova365 system, to the high-performance Azure cloud.
What we did
Instead of maintaining many small servers, we consolidated services. We reduced the number of virtual machines by 30%, moving databases to optimized Azure SQL instances that guarantee high I/O operation performance (crucial for accounting).
Secure Remote Work (Azure Virtual Desktop)
This was a revolution for employees. We implemented VDI (Virtual Desktop Infrastructure).
How it works
An accountant logs in from home on any laptop but "sees" a corporate desktop running in the Azure cloud.
The Effect
Data never leaves the cloud. Processing takes place on powerful Azure servers, and the employee sees only the image. This eliminated the problem of slow internet connections and unsecured home computers.
FinOps – Pay Only for What You Use
We implemented an aggressive cost optimization strategy:
Auto-scaling
At night and on weekends, when the office is not working, most VDI servers automatically shut down. The cost? Almost zero.
Reserved Instances
Key resources (SQL database) were reserved for 1-3 years, yielding an immediate discount of 40-60% compared to standard pricing.
Professnet Expert on the Project
The biggest challenge in accounting is 'input lag' during remote work. An accountant entering hundreds of invoices a day cannot wait a second for the system to react.
By using Azure Virtual Desktop in the same region as the SQL database, we reduced latency to almost zero. The application runs faster than on the old server sitting in the next room, even though it is physically located in a Microsoft Data Center.
Key Results & Business Impact
The transformation gave abcgo.pl a competitive advantage. They can scale their business without investing in hardware.
Financial
Infrastructure cost reduction (OPEX) by 40%. Money previously "burned" on electricity and server room cooling now stays in the company.
Operational
Employee efficiency increase by 20%. A faster system and no VPN issues mean more documents booked in the same amount of time.
Security
Full compliance with GDPR and ISO 27001. Central identity management (Active Directory) and MFA (multi-factor authentication) have practically eliminated the risk of unauthorized access.
Stability
SLA at the level of 99.9%. No more downtime during VAT declaration submissions.
Unquantified Value
Scalability on Demand
When abcgo.pl acquires a large client and hires 5 new accountants, we launch new virtual desktops in 15 minutes, not 3 weeks (waiting time for laptops and configuration).
Peace of Mind
The company board doesn't have to worry about drive failure or a server room fire. Cloud backup is automated and geographically redundant.
24/7 Support
Professnet monitors the system non-stop. We often react to problems before abcgo.pl employees even notice them (proactive monitoring via Azure Monitor).
