Finance and operations
A web ERP with finance, payroll and HR, procurement, manufacturing and fiscalization – in the cloud or on-premise.

Problem
Accounting lives in one program, HR in spreadsheets and invoices are fiscalized through a third tool. Data is retyped, errors surface at month end and reports for management and regulators are late.
When regulations change – contributions, tax-free amounts, fiscal requirements – each of those tools needs a separate update.
Solution
PERPER integrates years of experience with finance-driven organisations. The system is fully integrated, web-based and available from any device – it runs in the cloud or on-premise and is database-independent.
HR records, payroll, general ledger, fixed assets, inventory, procurement, manufacturing, financial statements, invoicing with fiscalization and cash desk all work on the same data. IFRS 9 and IFRS 16 are supported. Regulatory changes are applied centrally, for all clients at once.
PERPER is multi-tenant: every company has an isolated data schema. That is why there is an accounting-firm edition, in which an agency easily runs bookkeeping and finance for many companies from one system.
Modules
Employee files, contracts, leave, job history.
Salaries, contributions, taxes, bonuses and tax authority reports.
Chart of accounts, journals, period closing, customer and supplier ledgers.
