Frequently Asked Questions
Jonas isn’t a standalone job costing add-on. Costs are captured where they happen — field labor, materials, equipment, POs, and subcontracts — and flow straight into job costing and the general ledger, so your numbers are real-time and accurate instead of re-entered after the fact.
Every transaction across the ERP — time entry, material receipts, equipment usage, committed costs — updates the job the moment it’s recorded. There’s no overnight batch or manual import, so you always see where a job stands.
Yes. Jonas tracks budget vs. actual at the cost code and phase level, rolls in committed costs, and ties change orders to the job so your cost-to-complete and projected margin stay current.
Job costing, AP, AR, payroll, and the general ledger are one system. Labor hours cost the job and run payroll from the same entry, and every invoice or PO posts to both the job and the GL — no double entry, no reconciliation between tools.
Yes. Instead of exporting from accounting into spreadsheets to figure out job profitability, Jonas gives you live job cost reporting, WIP, and cost-to-complete inside one construction ERP.
