Topping up your balance
How to add money to your balance by card: allowed amounts, confirmation and the email you receive.
On this page
The “Alimentează soldul” (Top up balance) page (blackbox.md/checkout/topup, “Contul meu” (My account) → “Sold” (Balance) → “Alimentează soldul”) lets you add money to your BLACKBOX account balance with a bank card, through Paynet. You can then use your balance to pay for orders, invoices or a server upgrade.
Available to: the holder of the blackbox.md account, signed in on the website. You can top up your balance only by card (Visa or Mastercard).
The blackbox.md website is available in Romanian and Russian; this article quotes the Romanian labels with their English meaning.
How to top up your balance
- Sign in to blackbox.md and click “Cont client” (Customer account) in the top bar (on a phone, the round account icon).
- In the account menu, choose “Sold” (Balance). On a phone or tablet, first tap “Meniu cont” (Account menu).
- On the “Sold curent” (Current balance) card, click “Alimentează soldul” (Top up balance). The “Alimentează soldul” page opens, with the hint “Sumă între 50,00 și 50.000,00 MDL” (Amount between 50.00 and 50,000.00 MDL).
- Choose the amount: click one of the “100 MDL”, “250 MDL”, “500 MDL” or “1000 MDL” buttons, or type the amount in the “Altă sumă” (Other amount) field. You can also enter an amount with decimals, for example 75.50. If you type in the field, the button you selected earlier is deselected.
- Tick “Am citit și accept Termenii și Condițiile și Politica de Confidențialitate (v2026-09-03)” (I have read and accept the Terms and Conditions and the Privacy Policy). The links in this text open in a new tab.
- Click the button with the amount you chose, for example “Achitați 500,00 MDL” (Pay 500.00 MDL). The button stays inactive until you choose an amount and tick the agreement. While the payment is being processed, the button shows “Se procesează…” (Processing…).
- Your browser takes you to the Paynet payment page. Enter your card details and confirm the payment. You enter your card details only on the Paynet page: BLACKBOX does not see or store them.
- Paynet brings you back to blackbox.md, to the confirmation page (browser tab: “Confirmare plată — BLACKBOX” (Payment confirmation — BLACKBOX)). For a few seconds you see “Verificăm plata…” (Checking your payment…) and “Vă rugăm așteptați…” (Please wait…).
- When the payment is confirmed, you see “Sold alimentat!” (Balance topped up!) and “Alimentarea a fost confirmată. Fondurile au fost creditate în sold.” (The top-up has been confirmed. The funds have been credited to your balance.) Click “← Sold” (← Balance) to see your new balance.
What happens after payment
- On the “Sold” (Balance) page, a row with the description “Alimentare cont BLACKBOX” (BLACKBOX account top-up) and the amount with a + sign appears under “Istoricul operațiunilor” (Transaction history). “Sold curent” (Current balance) increases by the same amount.
- You receive an email at your account's email address, with the subject “Alimentare cont confirmată — BLACKBOX” (Account top-up confirmed — BLACKBOX) and the rows “Sumă alimentată” (Amount topped up) and “Sold curent”. The subject is always in Romanian, and the body of the email is in your account's language (see Language of the website, the panel and emails). In the email, amounts appear in whole MDL, without decimals: a top-up of 75.50 MDL appears as 75 MDL. You can see the exact amount on the “Sold” page, under “Istoricul operațiunilor”.
- If you turned on “Reîncărcare automată” (Automatic top-up) on the “Sold” page, right after the top-up the system uses your balance to pay the invoices that have reached their due date and that your balance covers in full. For each one, you receive the email “Factură plătită automat din cont — …” (Invoice paid automatically from your account — …). Details: Automatic payment of invoices from your balance.
- You can use the money in your balance to pay for a new order: see Paying for an order from your balance.
Limits
| Limit | Value |
|---|---|
| Minimum amount of one top-up | 50.00 MDL |
| Maximum amount of one top-up | 50,000.00 MDL |
| Maximum balance after a top-up | 200,000 MDL |
| Top-up attempts | at most 5 in 60 minutes |
| Validity of the Paynet payment link | 60 minutes |
Every click on “Achitați … MDL” (Pay … MDL) that reaches the server counts, including payments you did not complete on the Paynet page. The limit is calculated over the last 60 minutes, and attempts made while the limit is reached also count. So wait an hour before you try again. To add more than 50,000 MDL, make several top-ups. See also The “Too many attempts” message and usage limits.

|---|---|---|
| “Verificăm plata. Veți primi confirmare pe email de îndată ce este confirmată. Puteți reîncerca peste câteva minute.” (We are checking your payment.

Important If the page stays on “Verificăm plata…” (Checking your payment…), do not start a new top-up right away: first check the “Sold” page and your email, or you may pay twice. If the money was taken from your card but your balance has not increased even after a few minutes, write to us with the date, time and amount of the payment. Never send your card details.
Other situations: The payment failed or the status did not update.
Other ways
- Bank transfer: you cannot top up your balance by bank transfer from the interface. How to pay by bank transfer: Paying by bank transfer and BLACKBOX bank details.
- The AI assistant (MCP): it can show your balance and your transaction history, but it cannot top up your balance. See Orders, payments, cancellations and upgrades via AI.
- The app.blackbox.md panel: your balance appears in the top bar (“… MDL”). If your balance is not enough for an upgrade, the “Upgrade server” window shows the “Top up your balance →” link. Both the balance in the top bar and this link open the “Sold” (Balance) page on blackbox.md in a new tab, where you can top up.
Frequently asked questions
Can I top up with a card in euros or dollars? Yes. The payment is made in MDL, and the bank that issued your card converts the amount automatically, at its own exchange rate.
Is my card saved for future top-ups? No. BLACKBOX does not keep your card details and does not charge your card automatically. You start each top-up yourself.
Can I get the money in my balance back to my card? Not automatically. If you need a refund, write to support@blackbox.md.
Does my balance top itself up when it runs out? No. Despite its name, the “Reîncărcare automată” (Automatic top-up) switch does not take money from your card: it uses your balance to pay invoices that have reached their due date. See Automatic payment of invoices from your balance.
Do I get an invoice for a top-up? No: an invoice is issued when you pay for an order (by card or from your balance). If you need a document for the amount you topped up, write to support@blackbox.md. Details: The “Facturi” (Invoices) page: statuses, numbers and PDF.
