Sage 50

It is a Windows desktop application, so Mac users need a virtual machine or a hosted desktop, and every added remote worker becomes a hosting bill rather than another browser tab.
Multi user working shares a data file over the network, so all users effectively need to be on the same local network or on the same hosted server, and file corruption in a shared file environment is a recovery from backup rather than a support ticket.
The United States and United Kingdom editions are separate products with different tax engines, so a business trading in both markets cannot run one Sage 50 across them, and experience or add ons from one edition do not transfer to the other.
Additional users are licensed individually at full price, which means a part time bookkeeper, an approver who signs off purchase invoices and a manager who only ever reads reports all cost the same as the full time finance person.
Sage's development effort has moved to its cloud accounting products, so the eventual move off Sage 50 is a re-implementation with historical data conversion and a fresh chart of accounts rather than an in place upgrade, and that project only gets larger the longer the file grows.

Sage 50: Is Sage 50 cloud software?

No. The application runs on Windows and the ledger is a local file. The Sage 50cloud tiers add Microsoft 365 integration and a sync service for remote access, but the accounting itself is still desktop software.

Karbon: Is there a discount for annual billing on Karbon?

Yes, Karbon offers annual billing at a discount compared to monthly. Team plan is $59/month annually versus $79/month monthly. Business plan is $89/month annually versus $99/month monthly.

Source

Sage 50: Can my accountant work in it?

Yes, and many accountants in the United Kingdom and the United States know it well. Practically they will either take a backup of the company file, or connect through the remote data access service, or work on a hosted copy. Agree which of those before you start.

Karbon: What is the minimum user requirement for monthly billing on Karbon?

Karbon requires a minimum team size of 4 users to access monthly billing. Teams smaller than 4 must choose annual billing.

Source

Sage 50: Does it still require an annual subscription?

Sage moved Sage 50 to subscription licensing, so continued access and tax table updates depend on an active subscription. Confirm what happens to your ability to open historical data if you stop paying.

Sage 50: Is the United Kingdom version the same product as the United States version?

No. They share a name and a heritage but they are different codebases with different tax handling. Buy the edition for the country where you file.

Sage 50: What about payroll?

Payroll is a separate Sage product with its own subscription and per employee cost. Budget for it separately rather than assuming the accounting subscription covers it.

Sage 50: How hard is it to move to a cloud system later?

Expect to convert opening balances and a limited window of transaction history rather than the full file, and to redo the chart of accounts, the customer and supplier records and any custom reports. Most businesses do it at a year end for that reason.
