Accounting sync
What goes where, and who owns it.
Accounting stays the system of record for money. Purlin is where the project team sees it by cost code, and where commitments start.
Purlin sends
- Cost codes and phases
- Vendors and subs
- Subcontracts and purchase orders
- Approved change orders
Accounting sends back
- Bills and actual costs by code
- Payment status on each bill
- Vendor changes made in accounting
Cloud accounting syncs every 15 minutes. Desktop and hosted suites sync nightly and on demand through a small connector app on a computer that stays on. Payroll and paying bills stay in accounting.
API and webhooks
Build your own reports and connections.
On the Company plan, a REST API reads and writes projects, RFIs, submittals, logs, budgets and commitments. Webhooks call your system when something changes.
