Work Order and BOQ Management
Define detailed work orders linked to BOQs, quantities, and project scopes for accurate billing foundations.
Odoo Contractor & Subcontractor Billing Software
An Odoo-based contractor billing system for transparent measurements, RA bills, and controlled payouts.
Context
Construction and interior projects rely on multiple contractors operating across different sites, timelines, and scopes. Work orders, BOQs, measurement sheets, RA bills, and payments are often handled through spreadsheets, emails, and verbal confirmations. This creates gaps between what is executed on-site and what gets billed and paid. A structured billing system ensures that project progress, verified quantities, and financial transactions are tightly connected, reducing ambiguity and improving control.
Who this is for
We usually work best with teams who know building software is more than just shipping code.
This is for teams who
Construction companies managing multiple contractors
Interior and fit-out firms handling site-based billing
EPC contractors tracking project progress and payments
Developers overseeing subcontractor cost control
This may not fit for
Small projects without structured BOQs
Businesses not issuing work orders
Firms without subcontractor billing processes
Teams not requiring RA bill workflows
Problem framing
The operating reality
Project costs escalate when contractor billing lacks structure and transparency.
Manual measurement tracking leads to inconsistencies between site records and billed quantities. RA bills are often delayed due to unclear approval ownership and missing validations. Finance teams struggle to match work completed with invoices raised, while site engineers spend time resolving disputes instead of progressing work. Payment cycles become unpredictable, retention and deductions are miscalculated, and contractor trust weakens over time. Without a unified workflow, project-level cost visibility remains incomplete and reactive.
How this is usually solved (and why it breaks)
Common approaches
Manual measurement sheets maintained in spreadsheets
Billing approvals handled through calls and emails
Separate tracking of project progress and financial data
Delayed reconciliation of contractor invoices and payments
Where these approaches fall short
Frequent disagreements on billed quantities
Unpredictable and delayed contractor payments
Limited visibility into project-wise costs
Errors in retention, deductions, and adjustments
Delivery scope
Core capabilities we implement
Structured building blocks we use to de-risk delivery and keep enterprise programs predictable.
02
Digital Measurement Sheets
Capture completed work quantities on-site with structured entries, timestamps, and supporting images.
03
RA Bill Automation
Generate running account bills automatically based on approved measurements and contract terms.
04
Approval and Authorization Workflow
Implement multi-level validation to ensure every bill is reviewed and approved before payment.
05
Retention and Deduction Management
Systematically manage advances, retention amounts, penalties, and adjustments without manual errors.
06
Contractor Portal and Reporting
Provide contractors and teams with clear bill status, history, and project-wise cost insights.
How we approach delivery
01
Map contractor workflows from BOQ to final payout
02
Digitise measurement capture and approval at site level
03
Connect billing directly with accounting and payment processes
04
Build dashboards for real-time cost and progress visibility
Engineering standards at PySquad
We design contractor billing systems around actual construction workflows, not generic accounting setups. Starting from BOQs and work orders, we structure how measurements are captured, verified, and approved on-site. RA billing is then automated based on these validated quantities, with built-in approval hierarchies and financial rules. The system connects directly with accounting to ensure every approved bill flows into payments, deductions, and ledgers without manual intervention. The focus is on creatin

About PySquad
Short answers if you are deciding who builds and supports this kind of work.
- What is PySquad?
- We are a software engineering team. PySquad works with people who run complex operations and need tools that fit how they work, not software that forces them to change everything overnight.
- What do you get from us on a project like this?
- Discovery, build, integrations, testing, release, and follow up when real users are in the product. You talk to engineers and leads who own the outcome, not a rotating cast of handoffs.
- Who do we work with most often?
- Teams in logistics, marketplaces, marina, aviation, fintech, healthcare, manufacturing, and other fields where downtime hurts and clarity matters. If that sounds like your world, we are easy to talk to.
