FAQ
Questions we get every week.
Mid-market groups and PE-backed companies with several legal entities and several systems, typically from three entities upwards. Manufacturing, distribution, services, healthcare groups. If your finance team still builds reporting by hand and gets a lot of ad-hoc questions, Arc is for you.
No. Arc sits on top of your ERPs and reads them at the source. Keep Power BI for visualisation and LucaNet for consolidation if you like them. Arc is the layer that makes the numbers in them right, answers the questions they cannot, and does the work around them.
Within 24 hours Arc is connected to your ERP and answers its first questions. Over the first two weeks it learns your chart of accounts, cost centers and KPIs. From week 4 Arc works alongside your team, for example with a commented P&L every morning.
Everything in the ERP: general ledger bookings, invoices, payables and receivables, orders, deliveries and backlog, customers, parts, purchase prices and master data. All of it, across every entity, in one place. That is why Arc can answer questions no report was built for, and why nobody needs to log into the ERP to get them.
Read access at the source: ERP APIs, database connectors or DATEV exports, refreshed nightly or more often. Nobody at your company has to enter anything into a new system, and Arc never writes into your ERP.
In Germany, for both data processing and the AI models. Arc is GDPR compliant, comes with a data processing agreement as standard, and gives you an audit log and role-based access control.
Every figure Arc shows leads back to the bookings and order lines behind it, step by step. Reports are versioned and every change is logged. Nothing is sent without approval by a named person.
Arc is priced per legal entity. Prices start at €1,500 per month for DATEV-based groups and €2,500 per month for ERP-based groups, with volume discounts. All three products, automations, onboarding and hosting are included.
