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.; Maxio entry-level Grow plan starts at $599/month, making it costly for very early-stage startups.
  • They diverge on capability: Carta covers Cap table of record, Maxio covers Usage-based billing.
  • 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.

Maxio

  • Entry-level Grow plan starts at $599/month, making it costly for very early-stage startups.
  • Pricing above the Grow tier requires a custom quote rather than transparent self-serve pricing.
  • Focused specifically on B2B SaaS billing, so it lacks general e-commerce checkout or consumer payment features found in platforms like FastSpring.
  • Advanced features like multi-entity support and expense amortization are gated behind paid add-ons.

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.

Maxio: What does Maxio cost?

Maxio's Grow plan costs $599/month for businesses with up to $100k in monthly billings. Businesses above that threshold need the Scale plan, which requires a custom quote from Maxio's sales team.

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.

Maxio: Is there a free plan?

No, Maxio does not offer a free plan. The Grow plan at $599/month is the entry point, with unlimited users included at no extra cost.

Source
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.

Maxio: What does Maxio integrate with?

Maxio integrates with accounting systems like QuickBooks, Xero, and NetSuite, CRMs including Salesforce, HubSpot, and Pipedrive, and 20+ payment gateways alongside its own Maxio Payments.

Source
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.

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.

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.
