Construction Project, Inventory, Payroll & Accounting Software Solution

Integrated Construction EPC ERP is an all-in-one enterprise operational and financial platform engineered for construction contractors, EPC builders, and engineering project companies. It integrates project budget tracking, subcontractor Interim Payment Certificates (IPC), daily labor muster rolls, equipment plant hire, site material issues, and IFRS job costing.

What if your construction business finally had software that actually understood construction?

Every general contractor, specialty trade firm, and project owner knows the pain: job costs leak across spreadsheets, payroll compliance is a minefield of union rules and prevailing wage calculations, and the project P&L only surfaces after the damage is done. Off-the-shelf accounting tools were built for retail — not for a world where a single project spans dozens of cost codes, multiple subcontractors, phased billing milestones, and real-time equipment tracking down to the hour. The result is either an expensive ERP subscription that burns $18,000–$50,000 per year, or a custom build that consumes $50,000–$200,000 before a single report runs.

XERPz is different. This is a proven, production-deployed Software source code package — a full Visual Studio .NET solution purpose-engineered for construction project management, built over years of real-world operational experience, and now distributed globally by Alwajeez Tech, a Saudi-based technology company headquartered in Jeddah. You pay $499 once. You own the code forever. There are no seat fees, no annual renewals, and no vendor dependency to worry about. As a complete SaaS Software solution codebase built on the Microsoft .NET Software stack, XERPz is deployable on any Windows Server or cloud VPS in under a day — and thanks to its clean, modular architecture, it is fully modifiable using AI coding agents such as Claude Code, Cursor, and GitHub Copilot.

What Core Modules & Capabilities Are Included in This Solution?

A dedicated system built from years of experience with real construction businesses

• Construction-mode billing (Billing_construction) — Issue milestone and progress-based invoices that match the unique cash flow cycle of construction contracts, not generic sales invoices.
• Contract setup & contract profitability tracking — Define contract terms, milestones, and budgets; compare actual costs against contract revenue in real time to prevent cost overruns before they happen.
• Job & task management — Break projects into jobs and tasks, assign work packages to team members, and log daily progress — everything connected to the financial record.
• Multi-project financial isolation — Each construction project maintains its own chart of accounts and P&L, giving ownership and management total visibility per job site.
• Project financial statement & work tracking reports — Instantly generate per-project revenue-vs-cost analysis and progress reports, powered by Crystal Reports for pixel-perfect output.
• Phase-level cost tracking — Record labour hours, equipment usage, and material consumption down to the job phase level — the granularity that construction accounting actually demands.

Financial management & accounting

• Full double-entry accounting engine — Every sales invoice, purchase, collection, and payment auto-posts to the ledger without a single manual journal entry — eliminating up to 90% of accounting errors.
• Real-time Trial Balance, Balance Sheet & Income Statement — Financial statements are always current; no waiting for month-end processing cycles.
• Multi-level Chart of Accounts (Group → Accounts → Control → Head) — Built to accommodate complex construction cost structures and standard accounting hierarchies simultaneously.
• Accounts Receivable & Payable with aging reports — Track subcontractor payables and client receivables with full aging analysis and credit management controls.
• Cancelled voucher audit log — Voided entries are flagged and preserved — never deleted — providing a tamper-proof audit trail for compliance reviews.
• Day Book, Bank Book & Cash Book — Chronological transaction registers for every financial movement, instantly accessible from the browser.

Payroll, HR & labour compliance

• Complex payroll structures — Configure per-employee salary with allowances, deductions, overtime, and bonuses — handling the variable pay structures common in construction.
• Overtime (OT) management by job or client — Track and calculate overtime at the project or client level, essential for union-rate and prevailing-wage compliance.
• Attendance tracking with correction workflow — Daily attendance recording with an authorized-edit workflow ensures accurate timekeeping across field crews and office staff.
• Leave management, loan & advance recovery — Leave entitlements, loan repayment schedules, and employee advances are automatically factored into monthly payroll — no offline reconciliation needed.
• Provident Fund (PF) management — PF criteria setup, eligible employee tracking, approval workflows, and PF form generation for statutory compliance.
• Salary sheet processing in hours, not days — One-click payroll run produces a complete salary sheet ready for bank submission, reducing a 2–3-day manual process to under four hours.

Inventory, procurement & supplier management

• Real-time stock position across multiple warehouses — Know the exact quantity and location of every material — from rebar to HVAC components — at any moment across all storage sites.
• Purchase entry with automatic AP posting — Vendor invoices update both stock levels and the accounts payable ledger simultaneously, eliminating dual-entry and preventing over-payment.
• Stock adjustments with reason codes — Record damage, wastage, or audit corrections with full traceability, maintaining an accurate materials cost picture for each project.
• Barcode printing for inventory items — Generate and print barcodes directly from the system; no external barcode software required for site stock management.
• Vendor credit management & purchase history — Maintain complete supplier profiles, credit terms, and transaction history to support price negotiation and vendor performance evaluation.

CRM, communications & reporting

• Sales pipeline & CRM — Track leads, customer profiles, and territory performance with area-based sales analysis, giving management a structured view of the business development pipeline.
• SMS gateway & email dispatch — Send billing reminders, project updates, and bulk communications to clients directly from within the system — no separate marketing tool required.
• Collection plans & customer dues aging — Schedule and monitor outstanding receivables per client, reducing payment delays through proactive collection tracking.
• Enterprise reporting via SAP Crystal Reports 13 — Over 30 business reports covering accounting, sales, inventory, HR, and projects — rendered to screen, PDF, or print with pixel-perfect formatting.
• Internal notice board & messaging — Centralized staff announcements and inter-user messaging keep field teams and office staff aligned without external tools.

SaaS architecture, security & administration

• Multi-company / multi-project isolation — Run multiple construction entities or business units from a single installation, with fully isolated financial data per project ID — true SaaS Software solution architecture.
• Granular form-level & menu-level access control — Assign per-form CRUD permissions (Create, Read, Update, Delete) to every user — not just broad roles — preventing unauthorized access to sensitive financial or payroll data.
• Full audit trail with login history — Every transaction is tagged with the entry-by user and timestamp; all authentication events are logged — supporting internal investigations and compliance audits.
• Cloud-ready, IIS-deployable architecture — Deploy on Windows Server (on-premises), Azure, AWS, or any VPS; the application serves all users through standard HTTPS with session-based security.
• AI-agent ready codebase — Clean, modular ASP.NET Web Forms structure is fully compatible with Claude Code, Cursor, Gemini, and GitHub Copilot — extend or customize the Software source code without touching core logic.
• One-click database backup from the browser — Administrators can trigger a full SQL Server database backup without leaving the web interface, ensuring business continuity at all times.
