Integrate Your Construction and Accounting Systems
Custom API integrations use webhooks to listen for events in one system. They then map and push data like invoices or timesheets to the other system.
Syntora designs custom API integrations to connect construction management and accounting software. Our approach focuses on detailed data mapping and architecting reliable, event-driven services using technologies like FastAPI and AWS Lambda. This ensures accurate and automated data synchronization between your critical systems.
The scope of an integration project depends on the specific construction management platform and accounting system you use, such as Procore and QuickBooks Online, and the data you need to sync. A one-way invoice synchronization is a standard build. A two-way sync that handles change orders, job costs, and custom general ledger fields requires more complex logic and data mapping.
What Problem Does This Solve?
Many construction platforms offer a pre-built QuickBooks connector, but they are often rigid. They sync basic invoice headers but fail to map line items to specific job cost codes, a critical requirement for accurate project accounting. Change orders and subcontractor payments are frequently unsupported, forcing your bookkeeper to manually cross-reference two systems.
A typical failure scenario involves a 15-person residential builder using Procore. A project manager approves a subcontractor invoice, and the built-in sync pushes it to QuickBooks. However, it arrives without the correct job cost code. The bookkeeper must then manually find the invoice, look up the job in Procore, and assign the cost code. This happens for all 50 vendor invoices each month, delaying job cost reports by 3 days.
Trying to patch this with a generic automation tool fails because these platforms cannot handle the specific data structures of construction software. They struggle with nested line items on a change order or polling for updates on a specific `job_id`. A single API error often halts the entire workflow with no automated retry, leaving financial data dangerously out of sync.
How Would Syntora Approach This?
Syntora's approach would begin with a detailed review of the API documentation for your construction management platform (e.g., Procore, BuilderTrend) and your accounting system (QuickBooks, Xero). We would then use tools like Postman to test available endpoints and confirm what data can be accessed for jobs, invoices, and payments. This discovery process would produce a definitive data map that precisely defines how a 'Change Order' in Procore translates to a 'Journal Entry' in QuickBooks, for example.
The core integration logic would be built in Python, using a FastAPI service designed to receive webhooks and `httpx` for making asynchronous API calls to external systems. When an event occurs, such as an invoice being approved in your construction software, it would trigger this service. The application would fetch the full invoice details, validate the data against your specific business rules, and format it correctly for the accounting API. Syntora has built similar document processing pipelines using Claude API for financial documents, and the same robust pattern applies to construction documents.
The service would be deployed on AWS Lambda, a serverless platform well suited for event-driven processing and scalable operations. A Supabase Postgres database would be used to log every transaction and its API response status, providing an audit trail. If an external API like QuickBooks is temporarily unavailable and a sync fails, the request would be automatically queued and retried for a defined period.
Structured logging with `structlog` would be configured to pipe detailed error reports to a designated communication channel, such as Slack. This would provide immediate notification for any persistent sync failure, including the specific document identifier and a link to the transaction log. This approach offers clear visibility into integration health without requiring a separate dashboard.
What Are the Key Benefits?
Get Real-Time Job Costs in 2 Weeks
The build, from discovery to launch, takes 10 business days. See accurate job profitability reports instantly instead of waiting for end-of-month manual reconciliation.
Pay Once for the Build, Not Forever
A single fixed-price project replaces recurring monthly fees from generic connectors. Your ongoing hosting costs on AWS Lambda are typically under $20 per month.
You Own the Code and Infrastructure
We deliver the full Python source code and deployment scripts to your private GitHub repository. You are never locked into our service or platform.
Automatic Retries for API Outages
The system includes built-in retry logic and Slack alerts for persistent failures. Temporary API downtime from Procore or QuickBooks will not break your workflows.
Connects Your Exact Tech Stack
We build directly against the APIs for Procore, BuilderTrend, Xero, and QuickBooks Desktop/Online, mapping to your specific custom fields and general ledger codes.
What Does the Process Look Like?
API Access and Scoping (Week 1)
You provide API keys for your construction and accounting software. We map the data fields and define the exact sync logic. You receive a data mapping document for approval.
Core Logic and Sandbox Testing (Week 1)
We build the Python integration service and test it in a sandbox environment. You receive a video walkthrough showing a successful sync of sample data.
Deployment and Live Data Sync (Week 2)
We deploy the service to AWS Lambda and connect your live accounts. We sync the first 20 live documents while you verify them in your accounting system.
Monitoring and Handoff (Weeks 3-4)
We monitor the live system for two weeks to ensure stability. You receive the full source code, deployment scripts, and a runbook detailing operations.
Frequently Asked Questions
- How much does a custom integration cost?
- Pricing depends on the number of data types (e.g., just invoices vs. invoices, timesheets, and purchase orders) and the API quality. A one-way sync from a modern platform like Procore takes about 2 weeks. A legacy system with a poorly documented API might take 3-4 weeks. We provide a fixed-price quote after the initial discovery call at cal.com/syntora/discover.
- What happens if an invoice syncs with the wrong data?
- Before going live, we process your last 50 historical invoices in a 'dry run' mode. You receive a CSV showing exactly what data will appear in your accounting system for approval. For post-launch corrections, we can build a simple admin interface in Supabase that allows a non-technical user to manually re-sync a specific transaction.
- How is this different from a pre-built connector from the Procore Marketplace?
- Marketplace connectors are one-size-fits-all. They cannot map to your specific general ledger codes or handle custom fields for job costing. We build the mapping logic to match your exact bookkeeping process. You are not forced to change your accounting methods to fit the software's hardcoded limitations.
- Can you build a two-way sync?
- Yes, but we advise against it for financial data. Two-way syncs create a risk of data overwrites and reconciliation loops. A more reliable pattern is a one-way sync from construction to accounting for costs, and a separate one-way sync from accounting back to construction for payment statuses. This maintains a clear source of truth for all financial records.
- What happens when QuickBooks or Procore updates their API?
- API changes are typically backward-compatible. For rare breaking changes, which are announced months in advance, the integration will fail and send an alert. Our optional flat-rate monthly maintenance plan covers all work required to support new API versions, ensuring your syncs continue to function without interruption.
- Can this handle our volume of 1,000+ invoices per month?
- Yes. The system is built on AWS Lambda, which scales automatically. It processes each invoice as a separate event, so handling 100 invoices per day costs the same per-invoice as 10,000. We have built systems that process over 20,000 API calls per day without any performance issues.
