Where Calitem has the advantage
Documents from your team channels
Calitem receives invoices and documents from email, WhatsApp, Teams and shared repositories. A person in a store or warehouse can send a photo without installing another app. The documentation enters the same accounting process, although it arrives through different channels.
Extraction tailored to your documents
The AI extracts general data, lines and specific fields of your operation. Calitem processes up to 250 documents every five minutes, to absorb large volumes without transcribing invoices one by one. Fields with low confidence are reviewed.
Duplicate invoices under control
Calitem detects duplicate documents automatically. When the same invoice arrives through different channels, your team can identify repetition before it turns into more accounting work.
Matching invoices, purchase orders and delivery notes
Calitem matches the three documents line by line and checks references, quantities, prices and taxes. If more units are invoiced than received, or a price changes, it flags the difference for your team to review before posting.
Accounts and cost centers by line
One invoice can include expenses from several stores, departments or projects. Calitem assigns categories, subaccounts and cost centres to each line using your chart of accounts and the team’s previous classifications.
Approvals that follow your rules
Define who must approve based on the amount, legal entity, cost centre or supplier. Calitem routes each document through the appropriate workflow and can automatically approve transactions that meet your limits.
