These are product-engineering examples from SalePro and SalePro SaaS. They illustrate the same requirement-first approach LionCoders uses for customization and custom projects.
Product engineering · Finance
Integrated accounting and financial controls
The requirement: operational transactions should flow into auditable financial records instead of forcing the business to maintain a disconnected accounting layer.
- Double-entry journal architecture tied to sales, purchases, returns, expenses and payments.
- Accounts receivable, accounts payable, customer deposits and payment-account mappings.
- Trial balance, balance sheet, profit & loss, cash flow and chart-of-accounts workflows.
- Accounting health checks and guided repair paths for known failure states.
Operational resultSalePro can keep financial reporting connected to the transactions that create it.
Product engineering · SaaS
Warehouse-isolated multi-tenant operations
The requirement: users should only see the warehouses and operational data they are permitted to access, while designated administrators retain a wider business view.
- Warehouse-aware access across POS, sales, purchases, transfers and reports.
- Fail-closed scoping for direct URLs and data queries.
- Role-aware behavior for administrators, branch users and customer-facing access.
- Isolation extended into HRM and supporting operational workflows.
Operational resultMulti-location and SaaS deployments can separate day-to-day operational visibility without splitting the core platform.
Product engineering · Workflow controls
Field payment collection approval
The requirement: staff may collect customer cash or mobile payments in the field, but those collections should not alter final accounting until an authorized person approves them.
- Pending collection records with collector, method, reference and handover details.
- Approval, rejection, handover and reversal lifecycle with permissions.
- Exact-once posting into the normal payment/accounting workflow.
- Protection against duplicate approval and direct edits to finalized payments.
Operational resultField collections can be captured immediately while financial posting remains controlled and auditable.
