The front office, back office, and payroll controls contractors actually use.
These are the modules live in the product right now — tied to actual contractor workflows instead of generic accounting templates.
Progress billing + invoice collection

Job costing + margin tracking
See revised budget, actual spent, invoiced, profit, margin, and at-risk jobs before they turn into surprises.
Change orders that tie back to the job
Capture scope changes, markup, schedule impact, approval status, and unbilled change order value in one workflow.
WIP + contractor reporting
Schedule of values, percent complete, over/under billing, AR/AP aging, and contractor-first reporting in one system.
Payroll + certified payroll
Run payroll, export summary packets, track prevailing wage, and generate compliance statements for public work jobs.
Document control + job records
Keep contracts, permits, payroll backup, lien waivers, and supporting job documents organized in one place.
Banking + payables visibility
See cash movement, bank transactions, payables pressure, and vendor-side obligations without leaving the platform.
Bonding capacity
Track working capital, backlog, credit, CPA readiness, and estimated single and aggregate bonding limits.
Employee + customer portals
Give customers invoice/change-order access and employees paystub visibility without sending everything through email chains.
Stop fighting your accounting software.
OpsSlate Books gives you tighter control over cash, jobs, payroll, compliance, and scope changes — without stitching five tools together to run one construction company.
