NEXIOS LedgerPro

Books hub

NEXIOS LedgerPro

Books you own, on your own machine. Invoices, bills, estimates, purchase orders, fixed assets, payroll and reports — with your data in your own SQLite file, and a documented format the rest of the suite reads and writes through.

Local-first, by design. NEXIOS LedgerPro runs on your own computer or your own server — your bank and broker credentials never sit on someone else’s cloud. It is also the books hub for the rest of the PolyApps suite: other products exchange data with it through one documented, hash-verified format, with a preview before anything is imported — never a silent write.

Small-business accounting that doesn’t lock up your data

Most accounting software makes a quiet trade: in exchange for convenience, your books live on someone else’s servers, under someone else’s export limits. NEXIOS LedgerPro makes the opposite trade. Everything — the ledger, the invoices, the bank data, the payroll runs — lives in your own SQLite file. You can back it up, move it, or open it on a different machine without asking anyone’s permission.

Single-company and multi-company (accountant) editions are the same product, feature for feature — the only difference is how many isolated company files you’re working across. Most individual businesses want the single-company edition. The accountant edition is for a bookkeeper or practice managing several client companies at once, or a business that runs more than one legal entity and needs to keep them separate while still consolidating.

Registration is gated behind bcrypt password hashing, account lockout, CSRF protection and rate limiting, and every mutating request is validated server-side — this is a real production system, not a demo.

What’s in it

Invoices, bills, estimates & purchase orders
The full day-to-day cycle, plus customers, vendors, expenses, mileage, fixed assets, and budgets.
Live bank feeds, or manual import
Live feeds via Plaid, using your own developer keys — never a shared vendor key — or OFX/CSV statement import for banks outside Plaid’s coverage.
Real payroll, not a stub
Federal withholding sourced to IRS Pub 15-T, the Social Security wage base cap, Medicare, state tax and real pay stubs — with a duplicate-run guard so the same period can’t post twice.
Multi-currency, with your own rate source
Bring your own exchange-rate API key; the rate is always fetched server-side — a client can never hand the system a rate to trust.
Roles that mean something
Owner, accountant, bookkeeper and read-only — each scoped to what they should actually be able to see or change.
Automation rules
Watch for an overdue invoice or bill past a threshold, and either open an approval or send one notification — reviewable, never silent, never touching the ledger on its own.
A tamper-evident audit trail
Hash-chained, with every entry attributed to the real logged-in user, so an altered record is detectable, not just discouraged.
A bridge off QuickBooks
Import a trial balance or ledger history, map accounts once, and transfer in — for firms switching off QuickBooks Online or Desktop.
An accountant edition
One isolated file per client company, switchable from a single roster — the same product, built for a practice instead of a single business.

The hub the rest of the suite connects to

Other PolyApps products — and outside tools — exchange data with NEXIOS LedgerPro through one documented interchange format: hash-verified, previewed before anything is written, never a silent background sync.
