A managed AI agent that works inside NetSuite, QuickBooks, or Sage — entering transactions, reconciling accounts, and syncing data across systems — so your books stay current without the manual keying.
Your accounting system is the source of truth, but keeping it true is brutal — transactions keyed by hand, accounts reconciled line by line, and data copied between the ERP and everything else. Close drags on for days.
As a Finance / Controller, I need to close the books faster without more hours of data entry.
As a Owner / Founder, I need to trust the numbers in the ERP without a manual scrub.
As a Operations Manager, I need to keep the ERP in sync with our other systems automatically.
We map your accounting workflows — entry, reconciliation, and the syncs between systems — then build an agent that runs them and co-manage it so your books stay current.
The agent enters invoices, bills, and journal entries into the ERP from your source documents and systems.
It matches transactions against bank feeds and sub-ledgers, flagging anything that doesn't tie out.
Data flows between the ERP and your CRM, bank, and spreadsheets so everything agrees.
Recurring entries and checks run on schedule so month-end starts from a clean base.
Discrepancies route to your team with the entry and the mismatch highlighted.

What it does
What's included
We build financial back-office automation. A verified win in reconciliation:
Reconciliation was a nightmare. We had accounts at Schwab, Fidelity, and TD, plus our own general ledger, and nothing matched without three days of manual work every month. ThunderStaff built an automated reconciliation engine that matches transactions across all custodians, flags exceptions by variance threshold, and generates reconciliation reports with full audit trails. Month-end close went from 5 days to 6 hours. We stopped paying our bookkeeper overtime and our advisors finally trust the numbers in client reports.
The cost of a slow close is real: overtime, late decisions, and errors. An agent that handles entry, reconciliation, and sync compresses the close and frees your finance team for work that needs judgment.
Run the numbers in the ROI calculatorNetSuite, QuickBooks, and Sage are common, and the agent can work with most ERP and accounting systems through their APIs or — where needed — the browser.
You set the controls. Routine entries can post automatically; anything above a threshold or out of pattern is held for a human to approve.
Invoice processing handles the AP intake side. This is the broader accounting workflow — entry, reconciliation, and cross-system sync that keeps the whole ledger current.
Most builds go from process mapping to a live agent in days, starting with a free Process Blueprint.
