What is Calitem?
Calitem is the AI accounting system that automates accounts payable, from receiving documents to posting journal entries in your ERP.
It is designed for companies where each invoice can require several checks: finding the purchase order, checking what was received, allocating the expense and obtaining the right approval. Calitem connects this work with your accounting rules and business systems.
Where SOFIA AI has the advantage
Dispatch batching
SOFIA organizes the upload and preparation of groups of documents. It fits when the team receives a lot of documentation together during campaigns and wants to review the result in an organized way.
Validation of tax fields
The tool includes tax identification checks and fields such as bases, VAT and personal income tax. It is relevant when the preparation work requires checking the consistency of that data before exporting it.
Classification for the work period
SOFIA assigns information such as the fiscal quarter and distinguishes documentary categories. Helps organize batches when the accounting firm receives documents of different dates and nature.
Review of questionable data
The platform flags cases that need monitoring and detects duplicates. It is a capability shared with Calitem that matters when the team wants to focus its review on processing issues.
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.
AI-generated accounting entries
Calitem uses your chart of accounts and previous accounting decisions to generate journal entries and send them to your ERP. Allocations are included, so the team does not have to re-enter information that has already been processed.
Integrations that connect the entire operation
Calitem connects the ERP to stock systems, POS and internal tools using native integrations and an open API. Specific connections adapt to the flow and data your operation needs, to reduce manual transfers between systems.
Several companies, well-organized accounting
Calitem supports multiple legal entities and cost centres. Classifications and approval routes follow your operational structure, whether you are a group of companies or an accounting firm managing clients’ accounts.
Analysis of accounting information
Calitem allows you to analyze the accounting and accounts payable information it processes. Your team can use that data to track the operation and understand expenses, as well as complete the work on each invoice.
