Toolenza for Accountants
The day around the books
Full bookkeeping software (QuickBooks, Xero, FreshBooks) handles the ledger. Toolenza covers the fifty small calculations and one-off documents that happen around the ledger: a one-off invoice for a client who isn't in the system, the sales-tax-extraction math from a receipt, the salary-to-hourly conversion for a new hire negotiation, a CSV dedupe before importing transactions.
Every tool runs in your browser or returns a downloadable file. Nothing in your books crosses Toolenza's servers unless you explicitly upgrade to a Pro workspace to sync.

Frequently asked questions
It produces a clean, professional invoice with the standard fields (your business info, client info, invoice number, date, line items, tax, total, payment terms). The IRS doesn't mandate a specific format for invoices; anything that's a clear record of the transaction is acceptable. For W-9 / 1099 paperwork specifically, the PDF-fill tool can fill the official forms.
The state presets reflect the standard published rate per state. Local rates (city, county, special districts) vary widely and change frequently — for actual filings, always pull the current rate from the state's revenue website or your tax software. The calculator accepts custom rates so you can plug in the precise local figure.
It's a take-home estimator using a flat effective tax rate plus pre-tax deductions. For an exact figure that handles federal brackets, state tax, FICA, FUTA, SUI, local taxes, and pre/post-tax deductions, use payroll software or a CPA. This tool is for quick conversations like \"if we offered $80k, what would the take-home look like?\"
