Billing

Coritan bills each service on the billing cycle you chose when you ordered it: by the hour, week, month, quarter or year. You pay from your credit balance, with a saved payment method such as a card, a bank account or a PayPal account, or with cryptocurrency. Ways to pay lists every method. This section explains how charges are worked out and paid, and how to change or cancel what you pay for.

Your account also has an account plan: Free, Pro, Business or Enterprise. Every account starts on Free. The plan sets limits for the whole account, includes some email and sending at no charge, and sets how much Object Storage the account uses free each month (How account plans work).

Orders

An order raises one first invoice for everything in it: one billing cycle of the service, the first period of each add-on bought with it and any setup fees. Coritan takes what it can from your credit, and sets everything in the order up once the invoice is paid (Order a service).

Renewals

Coritan raises each renewal invoice up to 3 days before the service's renewal date, by default. It takes the invoice from your credit first and charges your default payment method for the rest.

Hourly services

After its first invoice, an hourly service has no invoices. Coritan takes its price from your credit every hour, up to a monthly cap (How hourly billing works).

Services billed by use

A web deployment, a Cloud Compute instance, a game server and a database ordered on your own account have no price of their own. Coritan measures what each uses by the second and takes the cost from your credit every hour, or puts it on your monthly invoice. Every account gets some use free each month (How usage billing works).

Object Storage

A pay as you go service costs $0 a month. Its renewal invoice has a line for each meter it used above your account's free amounts (How Object Storage is billed).

Missed payments

Coritan retries a failed charge on a schedule. A service whose invoice stays unpaid is suspended a day after the due date, by default, and deleted later (Failed payments and suspended services).

Your credit is held in US dollars and never expires. Invoices are in US dollars too. The currency your bank charges depends on how you pay (Currencies and countries).

In the sidebar of the dashboard, select Billing. The page has seven tabs. Your account plan is not one of them: once account plans open on your account, it has its own plan page.

Overview

One card says where you stand: Account credit (your balance, and whether automatic top-up is on), Due now (the total of your unpaid invoices, with Pay all when more than one waits) and Next payment (the first renewal that falls due). You pay with shows your default payment method. Under them are the Add credit card and Next 30 days, which adds up each renewal that falls due in the next 30 days and the rest of this month's use, with a Total. Recent activity lists your latest payments. Credit activity lists every time use took credit, with the service and the hours it paid for, and says how many days your credit lasts. Billing events lists price changes, moves between billing terms and caps applied (See your usage, budgets and credit activity). Your unpaid invoices are listed on the Invoices tab, not here. The balance is in US dollars, whatever your account's currency is.

Subscriptions

Every service on your account, what it costs and when it renews. A service billed by use reads Billed by use in place of a price. Filter by Active, Pending, Suspended, Ending, Failed or Ended; the last two show only while a service has that status. Select a service to open its billing (Manage your subscriptions).

Usage

What your services billed by use cost this month, by service and day, with a CSV of the rows, your budgets and Query a charge… for an hour that looks wrong (See your usage, budgets and credit activity).

Invoices

Every invoice, with its status, the Pay button for the unpaid ones, Pay all when more than one waits and a PDF of each (Pay an invoice).

Transactions

Every payment, refund and credit movement (Transactions and payment attempts).

Payment methods

Your saved payment methods, such as cards, bank accounts and PayPal accounts, auto-pay and automatic top-up (Manage payment methods).

Refunds

The refunds you asked for on paid invoices, and what staff decided (Ask for a refund). Query a charge… sits beside it for a charge that looks wrong but is not a refund.

Your account's billing mode is shown as Billing mode on your profile (Update your profile).

prepaid

The mode every new account starts in. You pay a service's first invoice before Coritan sets it up. Hourly billing and automatic top-up are for prepaid accounts only.

postpaid

A service on a monthly or longer billing cycle is set up without a first payment, and you pay an invoice at the end of each billing cycle. Hourly, daily and weekly plans still need their first payment before setup. A service billed by use needs none, and its use goes on a monthly invoice. Only Coritan staff can move an account to postpaid, so contact support to ask.

balance is in credit_currency, which is always USD. currency is your account's currency, which is not the currency of balance: an account set to euros sees EUR beside a dollar amount. Each entry in recent_transactions is one change to your balance: amount is positive for credit added and negative for credit spent, and balance_after is the balance it left. The list holds movements that the Transactions tab does not show, such as hourly charges and the credit from a downgrade.
