Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Justworks
- The published per-employee fee is the platform charge, not your cost; health insurance premiums and workers' compensation are billed on top and are usually several times larger, so the transparent price is transparent about the smaller number.
- Leaving a PEO is a project, not a cancellation: you must source your own health plan, obtain your own state employer registrations and unemployment accounts, and time the switch to a plan year, which typically takes months.
- Coverage is United States only, so the moment you hire your first employee in another country you are running a second system and Justworks handles them only as a contractor.
- PEO Basic looks like a cheaper way in but excludes the Justworks health plans, which is the main reason companies choose a PEO at all, so most buyers end up on Plus.
- Benefit plan choice is constrained to what Justworks has negotiated, and a company with strong preferences about carriers or network coverage in a specific region may find the options do not fit.
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.

Answered from the vendors’ own pages
Justworks: What does co-employment actually mean?
Justworks becomes the employer of record for payroll tax and benefits purposes while you retain full control over hiring, management and day-to-day work. It is a legal arrangement, not an outsourcing of your team.
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.
Justworks: Is the $79 figure my total monthly cost per employee?
No. It is the platform fee. Health insurance premiums, dental, vision and workers' compensation are additional and typically dwarf it.
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.
Justworks: Can Justworks employ people outside the US?
No. It can pay international contractors, but it is not an employer of record abroad.
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.
Justworks: What is the difference between the Payroll plan and the PEO?
The Payroll plan handles payroll and benefits administration under your own EIN at $8 per employee per month plus a base fee. The PEO adds co-employment and pooled large-group insurance at $79 or $109.
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.
