Top-ups, invoices and payment methods

How to add credit to your Didit balance, which payment methods are supported, how auto top-up works, and where to find your receipts and invoices.

You add funds to your Didit balance from Settings → Billing and plan in the console at business.didit.me, or programmatically through the top-up API. Each top-up has a $50 minimum, and tax is added automatically based on your billing address.

#Payment methods

Payments are processed through Stripe.

#Auto top-up

To avoid running out of credits mid-traffic, turn on auto top-up in Settings → Billing and plan: set the balance it should trigger at (between $20 and $2,000) and how much it adds (between $50 and $2,000). It needs a saved payment method, which you save by paying a top-up by card. With a saved payment method (card, SEPA, or US ACH), Didit charges that method for a set amount whenever your balance drops below a threshold you choose.

This is the single most useful billing setting to enable, because a balance that hits zero blocks all billable work once your monthly plan credit is used up, until it's topped up.

#Features that unlock with your first top-up

Phone verification and database validation only activate once your organization has made a first top-up. Free or promotional credit doesn't count as a top-up for this purpose.

Until that first top-up, a workflow that includes one of these features will skip it or fail the request - a session can even come back approved with its database validation step silently not performed. If a feature you configured isn't running and you've never topped up, this is the first thing to check.

#Checking your balance

Your current balance is in Settings → Billing and plan, and readable programmatically from the balance endpoint. It updates in real time as verifications are billed and as top-ups settle.

If you're monitoring it from your own systems, alert on a threshold rather than on zero - by the time it reads zero, requests are already failing.

#Receipts and invoices

Every top-up, automatic top-up and plan charge has a receipt you can download as a PDF under Settings → Billing and plan → Receipts; balance adjustments and failed charges are listed without one. On Enterprise invoicing, an Invoices section above the receipts lists your invoices, with their status and a way to pay them online. See the Billing and plan page.

Receipts come from charges: your first top-up adds the first one. If you haven't made a top-up yet, there's nothing to show - which is expected rather than a missing invoice.

Billing and invoice visibility is controlled by role: included for Owner by default, and an organization owner can grant it to a custom role. If a teammate can't see invoices, check their role before reporting it. See inviting team members and setting roles.

#A top-up that hasn't appeared

Card payments settle quickly; SEPA and ACH do not, and crypto depends on confirmations. Before reporting a missing top-up, check whether the method you used is one that settles on a delay.

If a card payment shows as taken and the balance hasn't moved after a few minutes, that's worth reporting - include the payment reference.

#Refunds

Credit purchases are non-refundable. Since top-ups last 12 months, and balance bought before November 1, 2026 never expires, any balance you've added stays usable for a long time - see how pricing and credits work.

#Capping spend during testing

The reliable way not to spend money while integrating is not a limit - it's a sandbox application, where billing is bypassed entirely. If you need a hard ceiling on a live application as well, ask support what's available for your organization. See testing in sandbox.

#If a session is being blocked

See fixing a "not enough credits" error - the cause is usually a paid feature in the workflow rather than the balance itself.
