Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

OnPay

  • OnPay operates only in the United States, so the first international hire means a second payroll vendor and a separate compliance model.
  • There is no native mobile application, only a responsive web interface, which employers with field or shift-based staff notice immediately.
  • The HR functionality is administrative and does not replace an HRIS, so performance, learning and any real workflow automation need another product.
  • Time and attendance is handled through integrations rather than natively, meaning hours arrive from a third-party system that has to be reconciled when it disagrees with payroll.
  • Reporting is functional but limited, and companies that want cost analysis by department, project or location generally export to a spreadsheet rather than build it in the product.

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

OnPay: How is OnPay priced?

As a single published plan with a flat monthly base fee plus a charge per person paid, with no feature tiers. Contractors are charged at the same per person rate as employees.

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.

OnPay: Does it handle payroll outside the United States?

No. It is US-only, in all fifty states, including multi-state filing at no extra cost.

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.

OnPay: Why do farms and churches use it?

It supports Form 943 agricultural filing, clergy housing allowance and Social Security exemption rules, and 501(c)(3) nonprofit payroll, which several larger providers do not.

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.

OnPay: Is there a mobile app?

No. Employers and employees use a responsive web interface, which is a genuine gap for shift-based workforces.

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.
