• Coordinating 20+ subcontractors by WhatsApp and email chains where instructions get lost and nobody has the same version of the scope?

  • Progress claims arriving in different formats with no standard approval workflow, causing payment delays and disputes?

Subcontractor Management Software

Custom subcontractor portals for general contractors who need scope distribution, RFI workflows, progress claims, compliance documents, and payment tracking in one place -- not email threads where the latest version is somewhere in the chain.

Built around the reality of how subcontractors work. A portal they log into to see their scope, respond to RFIs, submit progress claims, upload compliance certificates, and check payment status -- reducing the calls to your office and creating the audit trail you need when something goes wrong.

  • Scope and drawing distribution with version control so every sub has the current revision

  • RFI and technical query workflows with response deadlines and full audit trail

  • Progress claim submission, review, and approval with payment certification

  • Compliance document portal -- insurances, licences, SWMS -- with expiry tracking

RaftLabs builds custom subcontractor management software for general contractors covering scope distribution, RFI and technical query workflows, progress claim submission and approval, compliance document collection, and payment status tracking. Replaces WhatsApp threads and email chains with a structured digital portal where every instruction, approval, and submission has a traceable record. Most subcontractor management platforms ship in 10-14 weeks at a fixed cost with full source code ownership.

Coordinating subcontractors by email and WhatsApp doesn't leave a paper trail

Most construction projects run subcontractor coordination through email threads and WhatsApp groups. The scope is in an attachment buried in an email from week three. The RFI response came via a voice note. The progress claim is a PDF in a format that's different from every other sub's claim. The compliance certificate expired six months ago and nobody noticed until the safety audit.

When a dispute arises -- and it will -- you're assembling that paper trail manually, hoping you can find everything. When a subcontractor claims they weren't told, you have to search threads that span months.

A subcontractor management portal gives every subcontractor a structured digital workspace. They log in, access their scope documents, respond to RFIs through a tracked workflow, submit progress claims in a standard format, and upload their compliance certificates. You have a complete audit trail for every instruction, every submission, and every approval -- created automatically, without someone having to maintain it.

What we build

Scope and drawing distribution

Scope documents, drawings, and specifications issued to each subcontractor through a controlled portal. Every sub sees only the documents relevant to their package -- not your full project documentation. Revision tracking so superseded drawings are clearly marked and field teams always access the current issue. Distribution records showing who received which document and when. The version control that prevents a subcontractor building to a drawing you superseded two weeks ago.

RFI and technical query management

RFI and technical query workflows where subcontractors submit requests through the portal and responses route through your team to the relevant consultant. Response deadlines set per RFI with automatic reminders on overdue items. Markup attachments, revised drawings, and written responses attached directly to the RFI record. All parties notified when a response is issued. Closed RFIs searchable by trade, package, and date range -- the technical correspondence record that exists automatically, not because someone compiled it.

Progress claim submission and approval

Standard progress claim submission through the portal -- claim amount, work completed, supporting documentation, and variation references all captured in a consistent format. Claim review workflow routing to your QS or project manager for assessment, with partial approval support and reasons for any reduction. Payment certificate issued through the portal and downloadable in PDF. Payment status visible to the sub without them needing to call your accounts team. The claim process that takes three days instead of three weeks.

Variation management

Variation and site instruction workflows where scope changes are issued, priced by the sub, and approved or negotiated through a tracked process. Variation register showing all open, approved, and rejected variations per package. Budget impact of approved variations updated in real time. The variation record that exists without someone maintaining a spreadsheet -- and that you can produce in full if the contract goes to dispute.

Compliance document collection

Compliance portals where subcontractors upload required documents -- public liability and workers compensation insurance, licences, Safe Work Method Statements, induction records, and any project-specific compliance requirements. Expiry dates tracked with automatic reminders before certificates lapse. Work access flags that prevent a subcontractor's team from being granted site access if their compliance documents are out of date. The compliance record that protects you in a safety audit, not the one you're assembling the night before.

Payment status and subcontractor communications

Payment status visible to each subcontractor through their portal -- claim submitted, under review, certified for payment, and payment date. Reduces the payment enquiry calls that occupy your accounts and project management team in the week after claim cut-off. Broadcast communication to all subcontractors on a project, or targeted messages to specific trades. Site instruction acknowledgement tracking so you know which subs have read and accepted an instruction. The communication record that demonstrates you notified everyone you needed to notify.

Frequently asked questions

Subcontractor management software is a structured digital portal where general contractors distribute scope, manage RFIs and technical queries, receive and approve progress claims, collect compliance documents, and communicate with subcontractors. It replaces the combination of email, WhatsApp, and manual spreadsheets most GCs use to coordinate their subcontractor base. A dedicated platform makes sense when you're running multiple concurrent projects with ten or more subcontractors, when compliance documentation management is becoming a liability risk, when variation disputes are arising from unclear instruction records, or when progress claim processing is taking more time than it should because every sub submits in a different format. The value is the audit trail -- every instruction, every submission, every approval is captured automatically rather than assembled from memory when something goes wrong.

Yes. Subcontractor portals typically integrate in two directions: with your project management system so scope, programme, and document data doesn't need to be entered twice, and with your accounting system so approved progress claims flow through to payment processing without manual re-keying. The integration scope depends on what APIs your existing systems expose. Common integrations include construction PM platforms, Xero, QuickBooks, and Sage. We scope integrations during discovery and give you a clear picture of what's achievable before development starts. If your core project management system is a custom or proprietary platform, we'll assess the integration options based on what data it exposes.

RFI workflows can be configured with priority levels and escalation paths. Urgent RFIs are flagged at submission and route to the relevant consultant with a tighter response deadline and real-time notification rather than a daily digest. If a response is not received within the defined window, the system escalates to the next person in the approval chain and notifies the subcontractor that the RFI is being expedited. The response time configuration is adjustable per project and per RFI type -- not a one-size-fits-all deadline. The workflow also supports same-day verbal direction confirmed by site instruction, where the instruction is issued through the portal after the field decision is made and acknowledged by the sub.

A subcontractor portal covering scope distribution, RFI management, progress claims, and compliance document collection typically runs $30,000--$60,000. A more complete platform with variation management, payment status integration, and accounting system connectivity typically runs $60,000--$120,000. Cost depends on the number of integrations, the complexity of the claim and variation approval workflows, and whether the portal needs to support multiple project types with different compliance requirements. We scope every project before pricing it -- you get a fixed cost covering an agreed scope, with no surprise invoices as development progresses.
