Switching from QuickBooks Online
QBO migrations are usually simpler than Desktop ones — the interesting work is retiring the satellites: the POS app, the inventory app, the A2X subscription that QBO's model made necessary.
1. Export the lists
Customers, suppliers, products and the chart export from QBO as CSV; SeroBooks imports them.
2. Open clean
Trial balance at cutover, open documents entered so collections continue, stock from a count — the count matters doubly if inventory lived in a side app.
3. Map the satellites
Whatever the connectors did — POS sales, Amazon settlements, stock sync — identify the SeroBooks screen that replaces each, and cancel with confidence rather than hope.
4. Keep read access for a season
A downgraded/read-only QBO for reference beats re-importing history you will rarely open.
The one test that proves the move
Reconcile the first full month. The Banking screen shows the ledger's balance beside the bank's on the same row, so agreement is visible rather than calculated — and an unexplained difference is a finding to investigate rather than a number to adjust away.
When that reconciliation closes at zero and the trial balance balances, the opening position was right and the new books can be trusted.
What actually goes wrong
The usual mess is not the ledger — it is the orbit. A QuickBooks Online setup that has grown a point-of-sale app, an inventory app and a marketplace connector has four systems holding pieces of the truth, and a migration that only moves the ledger leaves three orphans behind.
Inventory it before you start: list every connected app, what it holds, and what it costs monthly. That list is both your migration checklist and, usually, your business case.
Open at a boundary, and keep the subscription one month longer
Cut over at a month or year boundary with opening balances rather than mid-period. Then keep the old subscription running for one extra month — it is the cheapest insurance available, and it lets the first reconciliation happen with both systems visible.
Cancel the connector subscriptions only after that reconciliation passes, not before.
How to know the cutover worked
One test settles it: reconcile the first full month in the new system. If the bank agrees, the trial balance balances, and the stock count matches what the shelves hold, the migration is sound — everything else is detail. Do that one reconciliation attentively, and trust the books thereafter.
Until then, keep the old system readable rather than deleted. Nobody has ever regretted being able to look something up, and read-only access to your previous ledger costs nothing.
