The books, the store, the bank. One ledger.
SeroBooks is accounting software that runs the whole business: invoicing, inventory, payroll, banking and year-end in one place — built for Canada and the United States, in native apps for every device, with an AI employee who asks permission.

One sale. Six things happen. Correctly.
Follow a single transaction through the product — every screen is a real capture from a live demo business, not a mock-up.
The invoice is already a ledger entry.
Scan or type, and the document does everything at once: provincial tax per line, inventory relieved, receivable opened, ledger posted. Print it, email it, WhatsApp it. Nothing to sync afterwards, because nothing was ever separate.
Stock moves itself — serials, batches, bins.
Every serialized unit answers 'did we sell this one, and when.' Every batch knows its expiry. Every write-off carries a reason and an author. Live levels per location, and a warehouse map that knows which shelf.
Tax decides itself, by destination.
HST in Ontario, GST + PST in BC, QST in Québec — per line, split into components, with PST resale exemptions on purchases where a province grants them. Sell into the United States and it applies state and local tax the same way, watching each state's nexus threshold.
The bank reconciles the way bookkeepers learned it.
Your ledger's number beside the bank's number. Tick what cleared, finish at exactly zero. CSV import with reusable rules covers any bank on earth; live feeds are rolling out and land in the same flow.
The books were posted the whole time.
P&L, balance sheet and cash flow read straight from the ledger, by location, by class, by job, against budget. Period locks enforced at the ledger, an audit trail on every line, and a year-end close your accountant can sign.
T2, GST/HST, T4 — from the same numbers.
GIFI codes suggested for the T2, a sales-tax return you file rather than copy, and payroll slips that reconcile to the pay you actually ran. Fixed assets carry CCA with the half-year rule. Nothing retyped.
Thirteen modules. One subscription. No connector tax.
The depth that other accounting software sends you to a third app for — payroll, inventory, Amazon, forecasting — is just screens here, posting to the same ledger.
Payroll for every province and territory — and the United States.
CPP, EI, QPP and QPIP; vacation pay, statutory holidays and overtime by each jurisdiction's own rules. T4, T4A, T5018 and W-2 returns built from the pay you ran.
Canada is four tax systems. The US is fifty.
Inventory with a memory
Serials, batches and expiry, bins with rack-and-shelf addresses, transfers in transit, assemblies from a recipe, landed cost carried on the goods.

Registers, classes on every line, jobs and sub-jobs, billable time and costs, recurring everything, a custom report builder — and a migration wizard with a dry run.
Forecasting that says why
Stock-out dates, reorder levels and seasonal peaks from your own history, with honest confidence bands.
Enterprise control, day one
A View / Allow permission tree over every screen and action, enforced on the server.
Native apps on every device
Signed apps, plus the web. One login and one ledger, with the same numbers on every screen.
Settlements, ads, returns, storage — on one P&L, to the penny.
Amazon nets orders, refunds, FBA and referral fees into one deposit and bills advertising somewhere else. SeroBooks pulls settlements and Ads spend itself, posts every component to the right account, and tells you who files the tax. Verified against a live seller's QuickBooks Desktop.
- Settlements posted fee by fee
- Advertising, TACOS, profit after ads
- Returns, reimbursements, claims
- Storage, Buy Box and traffic
Leaving QuickBooks? Calmly.
SeroBooks connects to QuickBooks Desktop and reads your company straight across, or imports an IIF file or QuickBooks Online exports. It runs a dry run before it commits, with a trial balance that has to balance first.
Other software gives you an AI copilot. SeroBooks gives you an employee.
Maya briefs you every morning, answers anything about your sales, stock and money, reads a receipt into a bill, and drafts the real work — purchase orders, journals, payment runs. Then she does the one thing that makes her safe to employ: she asks permission. Approved by you, audited forever, undoable in one click, with a kill switch.
Your accountant will approve. So will your auditor.
Period locks, permissions and duplicate-payment checks are enforced at the ledger and on the server, not only in the interface.
Period locks at the ledger
A closed period refuses writes at the posting layer, not in the UI. Year-end close rolls retained earnings and freezes the year.
Audit trail on every line
Who changed what, when, from which document — including the journal line each change superseded.
The books check themselves
Nightly tie-outs between documents and journals, ledger and statements; an invoice number can never be issued twice.
Signed, native apps
Windows, macOS, iPad and Android builds signed and notarized. Encrypted tokens, and a one-time code before any bank link.
Server-enforced permissions
A View / Allow tree over 207 nodes, enforced on the API — a button you cannot see is a request the server refuses.
Penny-verified bridge
The QuickBooks Desktop export is reconciled in production against a real seller's company file, account for account.
A payment can't post twice
Every money write carries an idempotency key and a version check, so a double-tap, a retry on a bad connection or two tills at once cannot record the same payment twice.
Checked before every release
Every release runs more than a hundred automated checks against real books — tax, ledger, payroll and a till-to-ledger round trip — and does not ship until they pass.
Talks to the systems your money already runs through.
Marketplaces, card terminals, bank files and the filing formats the CRA, Service Canada and the SSA accept.

Running a restaurant? That's SeroPOS.
Kitchens, tables, ticket printers and kiosks — our sister product runs the food side, on the same platform.
Meet SeroPOS →Yes — that is the whole design. Counter sales, inventory and the double-entry ledger are one system, so a sale is simultaneously a receipt, a stock movement and a posted ledger entry. Restaurants get the same idea in our sister product, SeroPOS.
Your accountant will approve. So will your till, your shelf and your bank.
