Finance System Build
We build closing, journal entry, and financial statement systems, integrated with billing and other systems.
What We Cover
From journal entry to closing, financial statements, and system integration — end to end.
Journal Entry System
We turn manual/spreadsheet journal entry into a system with rule-based auto-classification and approval workflows — cutting processing time and errors, even at high transaction volume.
Closing Automation
We automate repetitive closing tasks to shorten the closing period, designing the process so the finance team can focus on the exceptions that need real judgment.
Financial Statements & Reporting
We build real-time financial statements and management reports that update on approval, with data aggregation and lookup by the criteria you need.
Cost & Management Accounting
We build management-accounting areas like manufacturing/service costing and profit-and-loss by division, connected consistently with your financial accounting data.
System Integration
We integrate with billing, ERP, and groupware via API, designing mapping and validation logic so settlement and revenue data land accurately in the ledger.
Data Migration & Validation
We clean and migrate existing accounting data and validate balances and transaction history, including mapping for differing chart-of-accounts structures, to minimize discrepancies.
Our Process
From chart-of-accounts design to a stable first closing — a proven sequence.
- 01
Current-Process Diagnosis
We diagnose the current closing, journal entry, and integration setup, and pinpoint where recurring errors happen.
- 02
Chart of Accounts & Process Design
We define the chart of accounts and improved accounting process first. Skipping this step causes major rework later.
- 03
System Build & Integration
We implement journal entry, closing, and financial statement features and integrate with external systems.
- 04
Data Migration & Validation
We migrate existing data and validate integrity against real closing scenarios.
- 05
Go-Live & Stabilization
We launch the system and support the first closing cycle hands-on to stabilize it.
- 06
Operations & Maintenance
We keep the system maintained and improved as regulations and business needs change.
Frequently Asked Questions
What steps are involved in building a finance system?
We follow: current-process diagnosis → chart of accounts & process design → system build & integration → data migration & validation → go-live & stabilization.
Can it integrate with our existing billing/ERP systems?
Yes. We design mapping and validation logic through API integration so settlement and revenue data accurately reach the accounting ledger.
Can we build just part of it, like closing automation, instead of the whole system?
Yes. We recommend starting with the highest-frequency, highest-error areas first, then expanding in stages.
Is this suitable for smaller businesses too?
If a full build feels like too much, we'd recommend looking at JOUNBOO, our own accounting SaaS, first.
