ECOSIRE Construction Subcontract (Payment Certificates)
The ECOSIRE Construction Subcontract module adds back-to-back Subcontractor Payment Certificate (SPC) management to the ECOSIRE Construction Management core. It mirrors the IPC structure on the supply side: each subcontract package has its own BOQ-driven cumulative valuation, retention withheld from subcontractors, advance payments and their recovery, and a direct GL posting path from an approved SPC to an Odoo vendor bill.
This module requires ECOSIRE Construction Management.
Compatibility: Odoo 17 / 18 / 19 (Community or Enterprise) Price: $399 (one-time) License: LGPL-3 — up to 3 domain activations Category: Industries

What it does
- Subcontract packages — define scope packages for each subcontractor, each with its own BOQ items drawn from the main project BOQ, making back-to-back traceability straightforward.
- Cumulative SPC valuations — each payment certificate records period and to-date completion percentages per BOQ item, producing a running cumulative that matches the main-contract IPC period structure.
- Retention from subcontractors — configurable retention percentage withheld on each SPC; a separate retention release certificate is raised when the agreed milestone is reached.
- Advance payment and recovery — subcontract advances are tracked and deducted from subsequent SPCs until fully recovered, symmetrically with the main-contract advance handling in the Billing module.
- SPC-to-vendor-bill GL posting — an approved SPC creates a standard Odoo vendor bill with the correct cost accounts, retention payable to subcontractor, and advance recovery lines derived from the subcontract configuration.
