Upload scanned invoices. LibroCost reads every line, proves each value against the invoice's own arithmetic, and files the spend by vendor, project and company. Anything it can't prove waits for a person, so nothing wrong reaches your books.
Totals, line items and dates are checked against each other before they're imported.
Re-uploading an invoice shows exactly which pages and values match, and you decide.
By vendor, project or job site, material, and purchasing company.
