The short version

  • Each has a real cost: Carta pricing scales with the number of stakeholders on the cap table, so a company that grants options broadly pays a rising annual fee for employees and small angels who sign in once a year, and the cost keeps climbing after the round that justified it is spent.; 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.
  • They diverge on capability: Carta covers Cap table of record, Sage 50 covers Local company data file.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

Carta

  • Pricing scales with the number of stakeholders on the cap table, so a company that grants options broadly pays a rising annual fee for employees and small angels who sign in once a year, and the cost keeps climbing after the round that justified it is spent.
  • The cap table is a legal record assembled from years of board consents, so migrating to another provider means re-entering historical transactions and having counsel confirm the rebuilt table matches the signed documents, which is why most companies stay whatever they think of the service.
  • The product is built around United States company law and tax practice, Delaware entities, 409A and ASC 718, so a company incorporated in the United Kingdom, Europe or elsewhere gets a record keeping tool while the valuation and compliance features that carry the price are of limited or no use.
  • 409A valuations are delivered on a cadence and require a refresh after each material event or every twelve months, so a company that raises or changes materially is repeatedly back in a valuation process with fees and turnaround time attached, and a late valuation blocks option issuance.
  • Carta drew sustained criticism in 2024 over how customer cap table data intersected with its secondary trading business, and although it exited that activity the episode is a live reason to check what a vendor holding your ownership record is permitted to do with it.

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

Carta: Do I need Carta before I have employees with options?

No. Before options exist a spreadsheet reviewed by your lawyer is usually enough. The pressure to move normally comes at a priced round, or the first time you need a 409A to set a strike price.

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.

Carta: Is the 409A included in the subscription?

The subscription tiers bundle valuations differently and refreshes after material events can carry additional cost. Check what triggers a chargeable revaluation before you sign, because raising a round is exactly the moment you will need one.

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.

Carta: Can my accountant get the stock compensation numbers out of it?

Yes, it produces ASC 718 expense schedules and exports. If your accounts are prepared under a different framework, expect the schedules to be a starting point that your accountant reworks rather than something they post directly.

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.

Carta: Is it useful for a company outside the United States?

It can hold the share register and grants, and it does support some non United States structures. The 409A and United States tax workflow will not apply to you, so weigh it against local alternatives that understand your filings.

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.

Carta: How hard is it to leave?

Harder than the export button suggests. You can export the data, but the receiving system has to reproduce every historical grant, cancellation and transfer, and someone has to verify the result against the original signed consents.

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.

Carta: Who normally pays for it, the company or the investors?

The company, even though investors and counsel are frequent users. That is the usual complaint about the pricing model: the party paying is not the only party benefiting.

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.
