The summary.
WHERE MOST BUSINESSES SHOULD START
Email and collaboration, with individual accounts, a second authentication step, and a backup of mail and files.
The provider protects against their failures, not your deletions.
FOR ACCOUNTING SOFTWARE
Ask your accountant before choosing. A system they cannot work with costs you in fees.
Export your financial data regularly. It is your record and you must be able to produce it.
FOR YOUR WEBSITE
Shared or managed hosting is adequate for most sites. An unmaintained virtual server is worse than shared hosting.
For Nigerian visitors, a nearer server is noticeably faster.
FOR ONLINE SELLING
Confirm before committing that the platform works with the payment gateways your customers actually use.
FOR SHARED FILES
Agree the structure first, restrict external sharing, and review what is shared periodically.
Business files in a personal account leave with the person.
FOR LARGE MEDIA FILES
Synchronisation saturates upload and degrades calls. Work locally and synchronise finished work.
FOR AI SERVICES
Never submit customer data, credentials or confidential material, and tell your team specifically what is prohibited.
