Billing & credits

Plans and seats

Custodos bills per seat. A seat belongs to exactly one person, and you choose a plan for each person. This page explains the plans, how to change seats and when a change takes effect.

The four plans

Custodos has four plans: Mini, Business, Max and Enterprise. Prices are per seat per month and exclude VAT. If you pay a year in advance, you pay 20% less. The current overview is also on the pricing page.

What differs between the plans

In the app, every plan includes the same features: all allowed models, Company Brain, agents and the data-protection modes. The difference is the credits. A bigger seat brings more credits each month, and a seat's credits are the monthly budget of the person who sits in it.

Admins see how many credits a seat brings when they choose a seat under Members: every option names the plan, price and credits. What credits are and what happens when they run out is explained in Credits and throttling.

Mixing plans in one workspace

Every person in the workspace holds exactly one seat, and plans can be combined freely. A common setup is Mini for the workshop, warehouse and field staff, Business for the office and Max for the people who work with large documents every day. All seats sit in one workspace with one administration and one invoice.

You decide which seat a new person gets when you invite them, both by e-mail and with an invitation link. How that works is described under Inviting members. You can change a person's seat at any time later.

Changing a person's seat

Only admins change seats, on the Members page. The person moves to the new seat immediately and has its monthly budget from then on. A higher seat is charged pro rata immediately; a lower one only reduces the invoice from the next billing date.

  1. 1

    Open Members

    Click Members in the sidebar.
  2. 2

    Choose the new seat

    In the Seat column next to the person, choose the new plan. The list shows the price and credits of every plan.
  3. 3

    Confirm the cost

    If the change costs something today, Custodos shows the amount and waits for your confirmation. Only then is the seat switched.

When a change takes effect

More capacity applies immediately and is charged pro rata until the end of the current billing period. Less capacity only reduces the invoice from the next billing date, with no refund. These rules apply to workspaces that pay for their seats.

Changing the number of seats

Workspaces that pay for their seats see a Seats section on the Billing page. It shows, per plan, how many seats are booked and how many are In use.

  1. 1

    Open Billing

    Click Billing in the sidebar and go to the Seats section.
  2. 2

    Set the number

    Raise or lower the number per plan. You cannot set fewer seats than are in use: remove someone first or move the person to another seat.
  3. 3

    Review the change

    Click Review change. Custodos shows the pro rata amount for this billing month and the new monthly amount.
  4. 4

    Confirm

    Click Confirm. Fewer seats appear as a scheduled change with its date. Undo withdraws it. There is only ever one scheduled change; a new one replaces the previous one.

Paying monthly or annually

With monthly billing, Custodos invoices every month. With annual billing, you pay for the seats twelve months in advance and get 20% off the monthly price. The interval applies for the whole term of a subscription.

Credits run monthly in both cases. On the billing day a new month starts with a full budget. The billing day is the day of the month on which your workspace is billed; the next date appears on the Billing page under Next billing date. If a month does not have that day, the last day of the month applies.

With annual billing, new seats are charged pro rata until the end of the annual term. Fewer seats only lower the invoice amount at renewal; a removed seat stays paid until then and can be reassigned free of charge.

Changing or ending your agreement

Changing the billing interval or the payment method, or ending your agreement, is arranged with the Custodos team. Write to us via the contact form. Enterprise plans with their own contract are arranged the same way.

If your plan was agreed individually, you still adjust seats and tiers per person under Members.
