Coale Construction
From BOQ to certified payment construction finance can trust
Coale Construction is a finance-led construction project, contract, and cost-control platform built on the Frappe Framework and ERPNext. Measure work once through structured Bills of Quantities, certify progress monthly with automatic retention and previous-certified deductions, control variations with cost and time impact, and post the net-payable straight to an ERPNext Payment Entry. QA/QC, HSE, and document control capture the full site record, while earned-value metrics warn of overruns early. Every shilling traceable to a contract clause.
BOQ to certified IPC
Key capabilities
Bills of Quantities with Rate Analysis
Build submittable BOQs with nested sections and line items carrying trade, unit, quantity, rate, and amount. Record measurement sheets with length, breadth, and height roll-ups, build unit rates from rate analysis, and compare priced BOQs across bidders for fair, fast tender evaluation. Revision numbers and prepared-by / approved-by capture replace fragile spreadsheets.
Interim Payment Certificates (IPC)
Monthly progress claims codify the industry valuation: gross work done plus approved variations and materials on site, less retention, advance recovery, and previously certified, equals net payable. The math is computed and read-only on the certificate, and the net-payable links directly to an ERPNext Payment Entry. Defensible certificates finance pays exactly.
Construction Contracts & Milestones
Manage contracts with value, revised value, retention percentage, advance percentage, performance guarantee, and milestones, each linked to its BOQ. Every payment is tied to signed commercial terms, so the contracts manager enforces the agreement rather than reconstructing it.
Retention Release in Moieties
Retention held is derived from contract value times retention percentage. Releases are recorded per First, Second, and Final moiety with a live running balance and Payment Entry link, so withheld money is never forgotten, over-released, or disputed at defects-liability closeout.
Governed Variation Orders
Capture variations with reason, cost impact, and time impact in days through a Draft to Submitted to Under Review to Approved to Executed status flow. Approved variations flow into the revised contract value and the next IPC, stopping silent scope creep before it erodes margin.
Earned-Value Cost Control
Set budgets by cost category and track actuals in real time. Earned-value analysis surfaces Planned Value, Earned Value, Actual Cost, Cost Performance Index (CPI), Schedule Performance Index (SPI), Estimate at Completion (EAC), and Variance at Completion (VAC). Early warning long before an overrun compounds.
QA/QC, HSE & Document Control
Inspection Test Plans with hold and witness points, construction inspections, material approvals, NCRs, and punch lists prove quality. Daily site logs, manpower and equipment logs, toolbox talks, safety incidents, and permits capture HSE. RFIs, submittals, transmittals, drawing registers, and meeting minutes end the paper trail.
ERP-Native Finance & Automated Chasing
Progress claims and retention releases carry Payment Entry links; Purchase Orders, Stock Entries, Suppliers, and Tasks all carry the construction project reference, keeping procurement, stores, and the general ledger connected. Daily scheduled jobs chase overdue RFIs, submittals, and expiring permits, with a weekly project summary. Nothing slips.
Why teams choose this
- Turn any BOQ into a certified IPC with automatic retention and previous-certified math. No disputes
- Post net-payable valuations and retention releases straight to ERPNext Payment Entry
- Track every retention moiety to the shilling with a live release balance
- Stop silent scope creep with variation orders that capture cost and time impact
- Catch overruns early with built-in CPI, SPI, and estimate-at-completion
- Prove quality with inspection test plans, material approvals, NCRs, and punch lists
- Capture the full site record: daily logs, manpower, equipment, incidents, and permits
- Chase nothing manually. Overdue RFIs, submittals, and expiring permits alert themselves
