One system for daily plant operations.
An internal Laravel system I designed for the gas plant I managed. It brings operational and financial records into connected workflows, with reporting for the team. I defined the requirements and design, used AI-assisted development and introduced it to plant staff.

Bringing operational and financial records together.
Daily operations, sales, purchases, customer and supplier debts, checks, expenses, employees and financial accounts all influence one another. When they live in disconnected records, it becomes hard to see status, trace changes and produce reliable reports.
The system grew from a practical need into a broader internal management platform, built in versions as real workflows and reporting requirements became clear. Private data and source code are intentionally excluded from this public case study.
Nine connected modules.
Daily operations
Record operational activity and connect it to sales and reporting.
Sales & invoices
Invoices, line items, customer payments and balances.
Purchases
Suppliers, purchased items, paid amounts and remaining balances.
Customer debts
Receivables and payment status, visible at a glance.
Supplier debts
Obligations and supplier-level balances.
Checks
Received and issued checks, due dates, status and transfers.
Expenses
Dated, categorised expenses with reporting filters.
Employees
Identifiers, contact and payment information, structured.
Financial accounts
Cash, card, bank and transfer activity in ledger-style records.
Business rules between input and reporting.
Input
Operations, invoices and payments.
Rules
Laravel workflow and validation.
Record
Structured MySQL data.
Output
Admin views and reports.
Financial workflows leave little room for silent errors.
- Connected modules use consistent records and status rules.
- Amounts, balances and payment changes require explicit validation.
- Reports answer operational questions; they don't just display stored data.
- Incremental releases make workflow gaps and calculation issues easier to isolate.
Build, test with reality, then refine.
Map how operations and money actually move. Design the smallest useful version. Test it with real scenarios, correct calculation issues and interface gaps, then add modules and reports as requirements are validated.
The value.
- One structured place for connected operational records.
- Clear visibility into payments, obligations and account activity.
- Less dependence on scattered files and memory-driven follow-up.
- A system that evolves as business rules change, and a direct bridge to ERP platforms like Odoo.
