Accounting Systems Connector for AARO-integration
Otisco supports 90+ accounting systems with ready-to-use connectors that automate the flow of figures into AARO.
Whether you’re using SAP, Fortnox, Microsoft Dynamics, or Monitor G5, we help you integrate faster and smarter.
No two group structures are the same. Otisco was built with the flexibility to meet yours head-on.

Supported Accounting Systems
From day one, our goal has been simple: reduce complexity without cutting corners.
Use Cases & Benefits
Otisco supports finance teams across multiple industries by simplifying the flow of entity-level data into group consolidation tools.
As one Fortnox customer put it:
"Excellent tool for getting the numbers into our group consolidation program."
"Suveränt verktyg för att få in siffrorna i vårt koncernkonsolideringsprogram."

Group Reporting Automation
Otisco eliminates repetitive data entry and speeds up the transfer of financial data from local systems to AARO. This reduces delays and helps Group CFOs maintain consistent reporting timelines across entities.
Monthly Close Acceleration
By automating key parts of the reporting process and standardizing inputs, Otisco helps teams close their books faster every month. Group accountants spend less time chasing data and more time reviewing results.
Reduced Manual Errors
With validation tools, clear audit trails, and smart mapping, Otisco reduces the need for spreadsheet-based workarounds and error-prone manual adjustments. This leads to cleaner data and more confidence in your consolidated reports.
Deep AARO Expertise and AARO Consulting
Otisco has worked with AARO for about ten years: implementing it, reviewing existing setups and helping groups get more out of it.
That experience is built into the integration. Otisco knows how AARO expects the figures, so they arrive right the first time.
For groups with more sophisticated reporting requirements and ambitions, we also offer AARO consulting: implementation, system reviews, interim AARO experts and ongoing optimisation.
AARO Specification Forms
AARO asks for specifications of key balance sheet and cash flow accounts, such as fixed assets, equity, untaxed reserves, deferred tax and shares in subsidiaries. With the add-on Otisco Account Specifications, each company fills them in on the web, the specifications are checked against the company's own accounting, and they reach AARO together with the figures.
It supports all the standard AARO specification forms: BS_TANG, BS_INTANG, BS_EQUITY, BS_INV, BS_UR, BS_DEFTAX, CF_SPEC and CF_ALL_B.
Frequently Asked Questions (FAQ) Otisco with AARO
What does Otisco do with AARO?
Otisco collects the figures from each company’s accounting system, maps them to the group’s chart of accounts, reconciles and validates them, and delivers them to AARO. It removes manual steps, keeps the figures consistent and supports group reporting across many companies.
Which accounting systems are supported?
We support 90+ accounting systems, including Fortnox, Visma, Business Central, Monitor G5, Xledger and SAP. See the full list, or contact us about a specific system.
Do we need to replace our existing accounting systems to use Otisco?
No. Otisco works with the accounting systems your companies already use—no replacement or migration is necessary. We tailor the integration to your IT landscape and group structure.
Can Otisco support multiple entities and currencies?
Yes. Otisco handles multi-entity group structures, including local chart of accounts, currencies, and reporting rules—while centralizing control for group consolidation.
How long does implementation take?
The first company is usually connected within days, depending on system access. You'll start with a demo and a tailored proposal. Many customers start with a few companies and then scale up to all companies in the group.
Is the solution compliant with audit and governance standards?
Yes. Every change is logged in an audit trail and access is controlled per user, which supports audit readiness and internal control.
Do you offer local support in Swedish?
Yes. Our team is based in Sweden and all onboarding, support, and ongoing communication can be done in Swedish.
