Run your business.
Let TBA handle the paperwork.
The Business Assistant™ is a full back-office platform — accounting, invoicing, payroll, inventory, and reporting — built for businesses that have outgrown spreadsheets but don’t need enterprise complexity.
Get Started See what’s includedEverything your back office needs, in one place
No bolted-together add-ons — it’s one system, so your books, invoices, payroll, and inventory always agree with each other.
Real double-entry accounting
A GAAP-compliant general ledger with accrual or cash-basis reporting — financial statements that actually tie out.
Invoicing & getting paid
Quotes, sales orders, and recurring invoices, with AR aging so you always know who owes you and when.
Payroll & time tracking
A built-in timeclock and timesheets that feed straight into payroll and job costing — no separate app to reconcile.
Inventory & vendors
Track stock as it moves, manage vendor bills, and keep 1099 records current automatically.
Reporting that makes sense
P&L, balance sheet, and cash flow — actual and forecast — with drill-down to the transaction behind every number.
