Custom Workflow Automation for Construction Contractors
When estimates, change orders, job costing, and subcontractor management stop scaling on Procore, Buildertrend, and spreadsheet-based job cost tracking.
Construction contractors manage complex, high-stakes project financials across a fragmented set of tools. Estimating in a custom spreadsheet or Sage Estimating, project management in Procore or Buildertrend, subcontractor management in email and Word, job costing in QuickBooks, scheduling in a separate tool or whiteboard. Each project spans months, involves dozens of subcontractors, and generates a continuous stream of change orders, RFIs, submittals, and invoices. The financial exposure on a missed change order or an unbilled work item is significant. Most contractors have experienced a job that was profitable on paper and underwater at close because change orders weren't tracked and billed completely. We build the integration layer that keeps job cost, change order status, and subcontractor billing in sync so the project manager knows where every dollar is before the job closes.
Pressure-test your bottleneck›What Construction Contractors typically run
- Procore or Buildertrend for project management
- QuickBooks or Sage for job costing and accounting
- Bluebeam for document review and markups
- DocuSign for subcontractor contracts and change orders
- Custom spreadsheets for estimating
- Microsoft Project or P6 for scheduling
- Zapier for ad-hoc integrations
Workflows we automate
- Estimate to contract
- Assembling the bid, presenting to the owner, negotiating the contract, getting it executed, and setting up the job in the project management and accounting systems. Currently a multi-week manual sequence with high data re-entry.
- Change order management
- Capturing field changes, pricing them, routing for owner approval, getting the change executed, and billing it. Change orders that miss the billing cycle are the most common source of job underperformance.
- Subcontractor management
- Issuing subcontracts, collecting certificates of insurance, tracking scope and schedule, processing pay applications, and managing lien waivers. Currently a combination of email, DocuSign, and a spreadsheet.
- Job costing
- Mapping committed costs (subcontract values, material POs) and incurred costs (invoices paid) against the contract budget by cost code. Currently a QuickBooks report that someone runs and interprets manually.
- Submittals and RFIs
- Routing submittals from subcontractors through the GC's review to the owner or design team, tracking response time, and logging the result. RFI tracking is similar. Both are currently email-based.
- Owner billing and draw requests
- Preparing monthly pay applications, supporting documentation, lien waiver collection, and schedule of values updates. The draw request package is manually assembled each month.
Why no-code platforms top out for construction contractors
Procore is a comprehensive construction platform, and its built-in workflows handle submittals, RFIs, and daily logs well within the Procore environment. The gap is at the financial layer: job costing in QuickBooks or Sage is a separate system, subcontractor lien waiver tracking is often a spreadsheet, and change order billing timing depends on a project manager remembering to include it in the next draw request. Zapier can link Procore to QuickBooks for basic sync, but not with the conditional logic that job cost management requires.
Change order tracking is where money leaks most visibly. A project running 30-40 change orders over its life, each with its own pricing, approval, and billing sequence, is beyond what Procore's built-in change order workflow reliably closes the loop on when billing is in a different system. The project manager needs to know, at any point, which approved change orders have been billed and which are pending billing. Today that answer requires cross-referencing Procore with a QuickBooks report with the most recent draw request, which is a multi-step manual lookup.
Subcontractor lien waiver management is similarly manual at scale. A GC with 20 active subcontractors on a large project needs a conditional waiver (tied to each payment), an unconditional waiver (after payment clears), and lien releases at project close. Tracking which subs have provided which documents, chasing the missing ones, and holding payment until the waiver is in hand is a full-time administrative task on large projects. Automating the routing and tracking reduces it to exception management.
What we build
We build the integration layer between Procore or Buildertrend, QuickBooks or Sage, DocuSign, and the subcontractor management workflow. Python or JavaScript on PostgreSQL, deployed to the contractor's cloud account. The integration owns financial state across all systems and keeps job cost current without manual reconciliation.
Specifically: a change order tracker that records every approved change, maps it to the billing schedule, and flags any approved change that isn't included in the current draw request; a subcontractor payment pipeline that generates pay application requests, routes lien waivers through DocuSign on payment trigger, and holds payment release until the conditional waiver is returned; and a job cost dashboard that continuously reconciles committed costs and incurred costs against the budget by cost code, surfacing variances before they become losses.
The estimate-to-contract workflow is often the first build because it eliminates the most data re-entry. When the estimate converts to a contract, the job cost codes, subcontract amounts, and billing schedule should flow into QuickBooks and Procore automatically. Today, that data is typically re-entered by hand, which introduces errors and takes hours per new project.
Frequently asked
Do you work with general contractors specifically, or also specialty subcontractors?
Both. General contractors have the broadest integration needs: owner billing, subcontractor management, and job costing all in one project. Specialty subcontractors typically need a subset: their own billing to the GC, their own lower-tier sub management, and job cost tracking against their contract values. The diagnostic call maps your specific workflows and identifies the highest-friction points. We scope to what's actually expensive for your operation. Procore and Buildertrend both have APIs that serve GC and specialty contractor workflows, and the integration approach adapts to whichever is in place.
How does the change order billing tracker work in practice?
Each approved change order in Procore is captured by the integration, tagged with its contract adjustment amount, and added to the pending-billing queue. When you're assembling the monthly draw request, the integration generates a checklist of all approved changes that haven't yet been billed, along with their amounts. You review and confirm. The integration then generates the updated schedule of values for the draw request. Nothing is missed because the system tracks every approved change from the moment it's executed in DocuSign or Procore.
What about certified payroll and prevailing wage requirements on public projects?
Certified payroll reporting is a specialized compliance requirement that most contractors handle through payroll software (LCP Tracker, DIR, or state-specific systems). We can automate the data collection for certified payroll: pulling labor cost records from the project management system and payroll tool and formatting them for submission. We do not replace the certified payroll platform itself. If this is a requirement, we scope it explicitly on the diagnostic call and ensure the integration supports your compliance workflow. LCP Tracker integration is the most common path for federally funded projects.
Our accounting is in Sage 100 Contractor, not QuickBooks. Does that work?
Yes. Sage 100 Contractor and Sage 300 CRE are common in mid-size commercial construction, and we know their APIs and ODBC integration patterns. The job cost integration approach is similar to QuickBooks but uses Sage's job cost module as the target. If your Sage instance is on-premise rather than cloud-hosted, we document the network access requirements as part of the engagement and design the integration accordingly. Procore-to-Sage job cost sync is one of the more common first builds we do for commercial contractors.
What size contractor makes sense for this engagement?
Generally contractors running 10 or more simultaneous projects with annual contract volume where a few missed change orders or a billing delay represents meaningful financial exposure. The clearest signal is when a project manager has had a job close significantly under its projected margin and the post-mortem pointed to unbilled change orders or untracked cost overruns. That's the automation problem we solve. Buildertrend shops doing residential remodel work at that volume often find the draw request automation is the clearest starting point. We're direct about this on the diagnostic call when a contractor's volume doesn't justify the investment.
