Overview
Mechanical, electrical and plumbing contractors run several projects at once, each with its own budget, material requirements, site stores and subcontractors. When estimates live in one spreadsheet, purchases in another and site issues in a notebook, the real cost of a project is often known only after it is finished.
Spiralcode implements ERPNext so that purchases, material issues, expenses and subcontractor invoices are recorded against the project they belong to. Project managers and accounts can then compare what has been committed and spent with the budget while the project is still running.
Common challenges
Operational challenges for MEP contractors
Contracting businesses tend to have sound estimating skills but weak links between the estimate and what happens on site. These are the gaps that make project margins hard to protect.
Actual expenses are hard to compare with estimates
Costs are recorded in accounts by type, not by project, so building a budget-versus-actual view for one project means manually collecting purchases, issues and expenses.
Material requests disconnected from site requirements
Site engineers request materials by phone or message. Purchasing cannot easily check whether the request is within the project's planned quantities or already in stock.
Limited visibility into materials issued to each project
Materials move from the main store to sites and between sites without consistent records, so the material cost of a project — and leftover site stock — is unclear.
Subcontractor commitments and payments tracked separately
Subcontract work orders, measurements and payments are kept outside the main system, making it difficult to see total committed and paid amounts per project.
Project information spread across spreadsheets and accounts
Project managers, site teams and accounts each maintain their own records, and reconciling them takes time that should be spent managing the work.
Connected workflow
How project budgets, purchasing and site materials connect
The key principle is that every cost-bearing transaction carries a project reference. Once that is in place, project reports can be built from transactions rather than assembled by hand.
Step 01
A project record is created for each contract, with tasks for its main work packages. A budget can be set against the project for the expense accounts you want to control.
- Project
- Task
- Budget
Next: Record material requirements
Step 02
Site or project teams raise material requests against the project, specifying the items, quantities and required dates.
- Material Request
Next: Create and process purchase orders
Step 03
Purchasing converts approved requests into purchase orders to suppliers, carrying the project reference so commitments are visible against the project.
- Purchase Order
- Supplier
Next: Receive materials and record project stock movements
Step 04
Materials are received into a central store or a site warehouse. Issues to the project are recorded as stock entries so material cost is assigned to the right project.
- Purchase Receipt
- Stock Entry
- Warehouse
Next: Track expenses and subcontractor records
Step 05
Supplier and subcontractor invoices, employee expense claims and timesheets are recorded with the project reference, depending on what you need to capture.
- Purchase Invoice
- Expense Claim
- Timesheet
Next: Review budget versus actual
Step 06
Project costing fields and budget variance reports bring purchases, material issues, expenses and timesheet costs together for review against the budget.
- Project Costing
- Reports
ERP capabilities
Contractor ERP capabilities, grouped by business need
These are standard ERPNext capabilities used in a project-based configuration. Contractor-specific practices such as bills of quantities, progress billing or retention are assessed separately because they usually require configuration or custom development.
01
Structure projects
A consistent project record that costs can be attached to.
- Projects with tasks and task dependencies
- Project templates for recurring project types
- Project-wise budgets against selected accounts
02
Buy and supply materials
Purchasing tied to project requirements.
- Material requests raised against projects
- Supplier quotations and purchase orders with project reference
- Central and site warehouses with transfers between them
- Material issues recorded against the project
03
Capture project costs
Every cost-bearing record linked to its project.
- Purchase and subcontractor invoices tagged to projects
- Employee expense claims linked to projects
- Timesheets for labour cost, where relevant
04
Keep accounts aligned
Financial records that follow operational transactions.
- General ledger, payables and receivables
- Cost centres alongside project tracking
- Accounting entries posted from purchases and stock movements
05
Review project performance
Reports built from the transactions recorded.
- Project costing summary on each project
- Budget variance reporting
- Project-wise purchase and stock reports
Industry focus
Which records feed a project's cost picture
A useful budget-versus-actual view depends on knowing which transactions contribute to it. This is how the main records relate to project cost in a typical ERPNext configuration.
| Record | What it represents | How it relates to project cost |
|---|---|---|
| Budget | Planned spend for the project by account | The baseline that actual costs are compared against |
| Purchase Order | Agreed purchase from a supplier or subcontractor | A commitment that has not yet been billed |
| Stock Entry (issue) | Material moved from store to the project | Material cost assigned to the project |
| Purchase Invoice | Supplier or subcontractor bill | Actual cost booked against the project |
| Expense Claim | Site or travel expenses paid by staff | Actual cost booked against the project |
| Timesheet | Hours worked on project tasks | Labour cost, where costing rates are set |
Budget
- What it represents
- Planned spend for the project by account
- How it relates to project cost
- The baseline that actual costs are compared against
Purchase Order
- What it represents
- Agreed purchase from a supplier or subcontractor
- How it relates to project cost
- A commitment that has not yet been billed
Stock Entry (issue)
- What it represents
- Material moved from store to the project
- How it relates to project cost
- Material cost assigned to the project
Purchase Invoice
- What it represents
- Supplier or subcontractor bill
- How it relates to project cost
- Actual cost booked against the project
Expense Claim
- What it represents
- Site or travel expenses paid by staff
- How it relates to project cost
- Actual cost booked against the project
Timesheet
- What it represents
- Hours worked on project tasks
- How it relates to project cost
- Labour cost, where costing rates are set
Exact fields and reports depend on configuration. Requirements such as committed-cost reports, BOQ-based tracking or progress billing are reviewed during scoping.
Implementation
Our implementation approach for MEP contractors
For contractors, the most important decisions are how projects, cost categories and site stores are structured. We agree these with your project, procurement and accounts teams before configuring transactions.
- 1
Define project and cost structures
We agree how projects and tasks are set up, which cost categories are tracked, and how they map to your chart of accounts and cost centres.
- 2
Map procurement and site workflows
We document how site requests are raised and approved, how materials reach sites, and how subcontractors are engaged and paid.
- 3
Configure reporting
Project reports and budget views are configured around the questions your project managers and management actually ask.
- 4
Train, go live and support
Site, procurement, project and accounts teams are trained on their part of the flow, with support during the first project cycles.
What we assess before scoping
These answers shape the scope, the configuration and any integration or custom work.
- Number and size of concurrent projects
- How estimates and budgets are prepared today
- Cost categories and how they map to existing accounts
- Central store versus site stores and material transfer practice
- Subcontractor engagement, measurement and payment process
- Billing practice, including any progress billing or retention
- Existing accounting practices and systems to migrate from
Frequently Asked Questions
Yes. In ERPNext, purchase invoices, expense claims, timesheets and many other transactions can carry a project reference. The project record then summarises the costs recorded against it.
Yes. Material requests and purchase orders can reference a project, and materials issued from a store to a project are recorded as stock entries against that project, assigning their cost to it. Site warehouses can be set up where you keep stock on site.
Yes. Purchase orders, receipts and invoices are linked documents, and the accounting entries are created from them. The project reference carries through, so purchasing and financial records stay consistent.
ERPNext allows budgets to be set against projects for selected accounts and provides budget variance reporting. Combined with project costing on each project, this gives a budget-versus-actual view based on recorded transactions. The usefulness of the comparison depends on consistent project tagging.
Contractor-specific practices such as bill-of-quantities tracking, progress or milestone billing, retention, measurement-based subcontractor payments or specialised scheduling are not covered in the same way as core project costing. We review these during scoping and identify whether they need configuration, custom development or another tool.
