Serina is invoice automation software built for accounts payable and finance teams that process thousands of vendor invoices. It replaces manual entry and spreadsheet validation with an end-to-end pipeline: capture the invoice, verify the extracted data, route it to the correct approver, and keep every step visible to the finance team.
The platform leans on machine learning and LLM-driven OCR to read invoices accurately, including header information, line items, and tax details, for both vendor-based and service-based formats. Organization-defined rules then determine who approves what, so approvals move faster and comply with internal policy. A vendor portal lets suppliers submit invoices themselves and monitor status, which reduces back-and-forth.
Serina is offered in several product tiers for different invoice types, from direct and utility invoices through PO-based matching and vendor self-service, plus a separate accounts receivable product. It integrates with leading ERP and payment systems and publishes a pricing calculator and demo booking for teams that want a tailored quote. The vendor lists a UAE focus alongside a US offering.
Replace manual invoice entry with automated capture and validation, then route each invoice to the right approver based on policy rules.
Use the vendor portal so suppliers upload invoices and track status themselves, cutting follow-up calls and onboarding friction.
Track outstanding payments, spend by vendor, and approval bottlenecks in interactive dashboards for better cash-flow decisions.
