Setup & Cleanup

Accounting system migration without starting from a mess

Moving to a new accounting system is a chance to start clean. Done badly, it moves every old problem across and breaks the integrations on the way.

When you need to switch accounting systems

The current system no longer fits, but the books aren't perfectly clean, integrations depend on it, and there's never a good moment to switch.

  • Outgrown QuickBooks Desktop or a local package
  • Integrations that depend on the old system
  • Uncertain opening balances
  • No plan for historical data

How a clean accounting migration works

A migration is only as good as its opening position and the testing before go-live.

  1. 1

    Choose the cutover date

    Pick a clean date and a clear rule for which system gets which transactions.

  2. 2

    Validate opening balances

    Fix or confirm balances first, so receivables, payables and deferred revenue start correct.

  3. 3

    Test integrations

    Test invoices, payments, revenue and costs from connected tools before switching over.

  4. 4

    Verify after go-live

    Compare key reports in both systems before retiring the old one.

Migrations in tech companies

SaaS

Moving from QuickBooks to Xero with Stripe and deferred revenue means validating subscriptions and deferred balances before migration.

Finance for SaaS

MSPs

QuickBooks Desktop to Online usually means rebuilding ConnectWise GL mappings and testing agreements, products and COGS.

Frequently asked questions

Should we clean the books before migrating?

Fix what affects opening balances. Migrating from validated balances is often better than cleaning every historical detail first.

What makes a good cutover date?

Usually a month-end after the close, with a clear rule that all later transactions go into the new system only.

How should open invoices and bills be migrated?

As individual open items, so receivables and payables totals match the detail.

What reports should we compare after migrating?

Trial balance, P&L, balance sheet, receivables and payables ageing for the cutover period.

Do ConnectWise mappings need rebuilding when moving QuickBooks Desktop to Online?

Usually yes. Test invoices, payments, agreements and COGS before cutover.

What SaaS data needs checking before moving to Xero?

Subscription revenue, deferred revenue, Stripe clearing balances and open invoices.

What should be tested before go-live?

Every integration that posts to the accounts, using real transactions, and confirming they post to the right accounts.

Your company has enough moving parts already.
