Accounting systems that actually connect.

Accounting API integrations, fractional controller services, and POS integration cleanup for growing businesses.

What we do

Accounting API Integrations
Connect your accounting platform to the tools you already run—payments, payroll, banking, CRM, and more—with reliable, monitored data flows.
Fractional Controller
Experienced controller-level oversight without a full-time hire: month-end close, financial reporting, controls, and process improvement.
POS Integration Cleanup
Untangle messy point-of-sale to ledger syncs. Fix mappings, reconcile discrepancies, and restore trustworthy sales, tax, and deposit data.
Workflow Automation
Replace manual spreadsheets and re-keying with documented, auditable automation tailored to your accounting processes.
