QuickBooks Online and Desktop explained
QuickBooks Online runs through a browser and apps with data hosted by the provider. Desktop accounting software is installed on local computers or a server and traditionally stores the working company file in an environment controlled by the customer.
Names, editions and support differ by country. UK buyers should not assume a US QuickBooks Desktop article describes a current UK product.

Access and collaboration
Online software is designed for access from different locations, subject to permissions and service availability. An owner, bookkeeper and accountant can work from the same current data without emailing copies of a company file.
Desktop software may provide fast local access and established workflows but needs deliberate arrangements for remote use, concurrent users and file locking. Sending copies creates version-control risk.

Updates, tax and integrations
A cloud subscription normally applies updates centrally and can connect to banks, payment services, expense apps and other tools. Check the exact plan for VAT, Making Tax Digital, payroll, stock, projects and multi-currency.
Desktop systems can preserve a stable version but require the business to install updates and manage compatibility. Older versions may lose connected services or tax support even if the local software still opens.
Cost and ownership
QuickBooks Online uses subscription pricing that varies by plan, users and promotions. Add payroll, payments, advanced features and third-party apps.
Compare the normal price after the discount, not only the first months.
A perpetual desktop licence can look cheaper over time, but support, upgrades, hosting, backups, servers and IT administration still cost money. Some desktop products also moved to subscriptions.

Backups, security and availability
With online software, the provider manages core hosting and service backups while the customer remains responsible for access control, accurate entries and retained records.
Use multi-factor authentication, individual users and regular exports of essential reports.
Desktop software gives the business more direct control but also responsibility for backups, encryption, malware protection, recovery testing and off-site copies. A backup that has never been restored is not a proven recovery plan.

Feature and workflow differences
Do not compare labels alone. Test bank reconciliation, invoices, bills, VAT, reports, attachments, audit trail, stock, jobs and accountant adjustments.
Some advanced desktop workflows may not map exactly to Online, while Online may offer collaboration and integrations the old workflow lacked.
Ask which reports are essential and whether custom templates, memorised transactions or third-party add-ons can be migrated.
Migrating to QuickBooks Online
Back up and reconcile the old system first. Decide how much history to move, map the chart of accounts and tax codes, and check customers, suppliers, open invoices, bills, bank balances and VAT returns after conversion.
Run key reports in both systems at the cut-over date and keep a secure archive. Test payroll and app connections separately.
Arrange migration support for a complex file rather than assuming every field will convert automatically.
Frequently asked questions
Is QuickBooks Desktop still available in the UK?
Product availability and support change by country and edition. Check the current QuickBooks UK product and support pages rather than relying on US or historic information.
Is QuickBooks Online better than desktop software?
It is stronger for remote access, collaboration and connected services. A desktop workflow may suit specific legacy needs, but requires local IT, backups and current support.
Test the exact features you use.
Will all Desktop data migrate to Online?
Not necessarily. Lists, balances and transactions may convert differently from templates, attachments, payroll, reports and add-ons.
Reconcile both systems and retain an archive.
