The short version

  • Each has a real cost: Billin plan Basico caps usage at just 5 clients, 1 user and 10 products for EUR 6.60/month, well below what most active small businesses need; 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.

Where each one falls short

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

Billin

  • Plan Basico caps usage at just 5 clients, 1 user and 10 products for EUR 6.60/month, well below what most active small businesses need
  • Plan Pro still caps clients at 50 and users at 3 for EUR 14/month, so any business with more clients must move to the unlimited EUR 23/month tier

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.

Answered from the vendors’ own pages

Billin: What are Billin's plan costs?

Billin offers three plans: Básico at €80/year (€6.60/month), Pro at €168/year (€14/month), and Ilimitado at €276/year (€23/month). Annual billing includes 18% savings compared to monthly.

Source
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.

Billin: Is there a free trial for Billin?

Yes, Billin offers a 30-day free trial with all features included. No credit card is required to start.

Source
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.

Billin: How many users does each Billin plan include?

Básico includes 1 user, Pro includes 3 users, and Ilimitado includes unlimited users.

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.

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.
