Accepting USDC and stablecoin payments on invoices

How USDC speeds up your cash flow

USDC settles in seconds on Solana and typically within about 15 minutes on Ethereum, Base, Avalanche, and Tempo. Bank transfers take longer: ACH runs up to 3 business days and SWIFT up to 5.

The settlement window matters most on weekends. Stablecoin networks do not observe banking cut-off times, so a transfer sent on a Friday evening doesn't wait for Monday's banking window. In Q2 2026, 12% of Altitude's payment volume moved on weekends (CEO, X, 2 August 2026). That reflects usage on stablecoin transfers, not every bank payout.

That speed translates directly to cash flow. A payment that arrives in minutes instead of days means you can pay your own contractors sooner.

Save money on global payment flows

Cross-border bank transfers layer fees: your bank charges an outbound wire fee, intermediary banks deduct processing charges, and the recipient's bank may take another cut. A median outgoing international wire transfer at the US banks and credit unions NerdWallet surveyed costs $45, and delivery can take several business days, with intermediary banks potentially deducting additional charges.

ACH (Automated Clearing House, the US bank transfer network), same-day ACH, US domestic wire, EURC-funded SEPA (Single Euro Payments Area transfers), and supported stablecoin transfers carry no Altitude fee. Outbound SWIFT (the international wire transfer network) costs $35 with a $100 minimum, as of September 2026. Sending, intermediary, and recipient banks may still charge.

The total cost of accepting USDC is the sum of platform fees, network fees, and off-ramp conversion costs. Altitude charges no platform fee on supported stablecoin transfers and the network fee is included. Conversion between USDC and EURC carries no fee from Altitude, but the executed rate and any slippage apply.

Why some customers prefer to pay in USDC

A crypto-native company, an exporter with international suppliers, or a distributed team may already keep operating balances in stablecoins. USDC is how they operate.

Paying you in USDC lets them avoid their own bank's wire fees and multi-day settlement delays, if they already hold USDC. Buying it first can carry on-ramp costs. "It also gives them a clean audit trail: every USDC payment produces a transaction hash that is proof of payment, with a timestamp both sides can verify. When you accept USDC, you remove friction on their side and make it easier for them to pay you.

Where to hold your incoming USDC

Before you share a deposit address with a customer, you need somewhere for the funds to land. Three options exist, and the difference between them is how much operational overhead you take on for every payment you receive.

1. Self-managed custody: You control the keys and the funds through a crypto wallet. You also handle every conversion, transfer, and reconciliation step manually. If you lose the keys, the funds are gone.
2. Exchange account: Simplifies conversion to fiat but adds counterparty risk and another login. You trust the exchange to honor withdrawals when you need them.
3. Global business account that holds USDC natively: Your deposit address is on Solana. Your business controls the account, and every payment follows the approval rules your team sets. Balances are held in fully reserved stablecoins, backed one to one by the issuer's reserves, controlled by your business and not lent out by Altitude. The operational difference is consolidation: one login, one balance, one set of approval rules.

Accepting USDC payments on your invoices

Altitude's invoicing supports USD and EUR invoices with payment terms you set: On receipt, Net 15, Net 21 (default), Net 30, or a chosen date. The only difference from a standard invoice is the payment method.

Match deposits to invoices

Altitude's accounting sync posts transactions to QuickBooks Online and Xero. The sync is one way, you confirm each posting before it applies, and invoices don't sync. EUR postings require a QuickBooks Online multi-currency subscription. If you run a different ledger, you can export a QuickBooks-compatible CSV and import it manually. For the matching workflow, see "Step 3: Managing your incoming transfers" below.

Why a global business account suits stablecoin receivables

Finance teams that receive stablecoin payments need an account that can hold USDC without routing it through a separate custody solution or exchange.

Altitude opens accounts for eligible businesses from 200+ countries with no US entity required. Product availability varies by country, and every business goes through verification. The account comes with dedicated US routing numbers and SEPA IBANs (International Bank Account Numbers for European transfers), so you can receive ACH and SEPA payments alongside USDC.

For SEPA and SWIFT deposits, the beneficiary name on the incoming payment must exactly match your account's legal entity name, or the transfer may be returned. SWIFT deposits must arrive in USD and require a separate pay-in approval before funds are credited. USD and EUR account details depend on your country and address. Check supported country availability before relying on either.

Step 1: Set up your USDC receiving address

Your receiving address is where customer payments land. That address is a USDC deposit address on Solana, controlled by your business. USDC sent on Ethereum, Base, Avalanche, or Tempo credits as USDC on Solana, typically within about 15 minutes. Every payment follows the approval rules your team sets, applied automatically, every time.

Step 2: Define your stablecoin payment terms

Your invoice needs four pieces of information:

• The amount due
• The currency (USD or EUR)
• The payment deadline
• The deposit address

Altitude's invoicing handles the first three. Payment terms matter more for stablecoin invoices because the payment is irreversible. State the network explicitly on the invoice: "USDC on Solana" or "USDC on Ethereum." Stablecoins sent on the wrong network cannot be recovered.

Step 3: Managing your incoming transfers

When a customer pays, Altitude credits the USDC deposit to your USD account. You open the invoice in your dashboard, see the deposit, and match it to the invoice. One matched deposit marks the whole invoice as paid. Altitude doesn't track partial payments, so if a customer pays half, you note that outside the system.

The transaction hash is your proof of payment. Deposit matching is manual today: you match a deposit to the open invoice in the dashboard. Automatic matching is in development.

Step 4: Pay out in local currency

You can hold USDC as USDC, convert it to EURC, or pay out in local currency through a payout rail to a recipient's local account. Altitude funds local payouts in GBP (Faster Payments), MXN (SPEI), BRL (Pix), and COP (Bre-B, a local payment system for Colombian pesos, or local bank transfer) from USDC in a USD account.

Local payouts go to the recipient's local account and don't create a local-currency balance in your Altitude account. They need workspace enablement and route approval. For BRL payouts via Pix, see the Pix help article for current fees, minimums, and delivery times. Fee position, timing, minimum, and maximum for SPEI, Faster Payments, and Bre-B are not published. The quote fixes either "You send" or "Recipient receives" and shows the effective rate and both amounts before you approve.

Handling taxes on stablecoin revenue

For US federal tax purposes, virtual currency is treated as property, and a taxpayer who receives virtual currency in payment for goods or services must include the fair market value in U.S. dollars as of the date received, per IRS Notice 2014-21. Notice 2014-21 predates stablecoins.

The GENIUS Act (Guiding and Establishing National Innovation for US Stablecoins), signed in July 2025, established a federal framework for dollar stablecoins in the US. Under the Act, issuers must hold reserves of at least 1:1 in assets such as cash and short-term Treasurys and publish reserve composition monthly, once the regime takes effect.

Record the USD value at receipt. Altitude's accounting sync posts transactions to QuickBooks Online with your confirmation. Your accountant determines the specific tax treatment for your jurisdiction. This is general information, not tax advice.

Securing your USDC payment flow

The freeze question often comes up when a founder evaluates a stablecoin account. Altitude cannot access or move your funds unless the approval rules you configured are met. Circle, the USDC issuer, can freeze USDC addresses under legal orders. Regulated partners can suspend services independently.

Balances are held in fully reserved stablecoins, backed one to one by the issuer's reserves, controlled by your business and not lent out by Altitude. Circle publishes monthly reserve attestations by a Big Four accounting firm. The Squads Protocol (the underlying infrastructure that enables the approval rules your team sets) is formally verified and has secured $10B+ in value across four years of operation, as of April 2026.

Approval rules are your first line of defense. You set the threshold, and every payment follows those rules automatically, every time.

What accepting USDC actually costs

Accepting USDC costs you the sum of three components:

The table covers the cost of receiving USDC deposits. The sender's own network fee, for example, a Solana transaction fee, is paid by them and is not covered by Altitude. Fees as of September 2026. Sending, intermediary, and recipient banks may still charge.

Compare that to a SWIFT wire: $35 fee from Altitude, $100 minimum as of September 2026, plus any intermediary charges. Stablecoin deposits carry no Altitude fee. For a full cost comparison against card processors, see USDC payments vs legacy processor fees below. Any conversion to local currency carries slippage on the executed rate.

Checking supported stablecoin networks

Altitude credits only USDC and EURC to your account. Altitude accepts EURC on Solana. Any other token sent to your deposit address cannot be recovered. See Recovering USDC sent via unsupported chains below. Confirm the network before you share a deposit address. Altitude supports USDC on Solana, Ethereum, Base, Avalanche, and Tempo. USDC sent on Ethereum, Base, Avalanche, and Tempo credits as USDC on Solana. If a customer asks to pay in USDT, DAI, or any other stablecoin, the answer is no.

Comparing USDC and bank wire fees

USDC settles faster than ACH or SWIFT and carries no Altitude fee, as ACH and SEPA also do. The trade-off is that not every customer can or will pay in USDC. You still need bank transfers for customers who pay by ACH or wire. Altitude supports both.

How USDC bridges currency mismatches across borders

A customer can pay you in USDC regardless of whattheir local currency they hold. If they hold MXN, theycurrency. They convert tolocally, send USDC through their own provider and send it to your deposit address. Youaddress, and you receive USDC.it. From there, Altitude lets you fund afunds local payoutpayouts in GBP, BRL, MXN, or COP directly from your USD account balance, without you holding local currency yourself.currency.

That means a Brazilian supplier can receive BRL via Pix, a UK contractor can receive GBP via Faster Payments, and a Colombian vendor can receive COP via Bre-B, all from a single USDC balance in one account. The customer pays in the currency they hold. The supplier receives in the currency they need. USDC moves in between, settling in seconds on Solana, outside banking hours.

This matters most when a bank wire would otherwise require both sides to absorb FX costs at their respective banks, wait up to five business days, and depend on intermediary banks that may deduct further charges along the way. USDC removes the intermediary legs. Local payouts need workspace enablement and route approval before first use, and the quote fixes either "You send" or "Recipient receives" with the effective rate shown before you approve.

Fees and settlement times for outbound payments as of September 2026. Sending, intermediary, and recipient banks may still charge on bank rails. For deposits, Altitude charges no fee. The sender's own network or bank fees are not covered by Altitude.

USDC payments vs legacy processor fees

Stablecoin deposits carry no Altitude fee. If you convert to EURC to pay a European supplier, Altitude charges no conversion fee, but the executed rate and any slippage apply.

Selecting the right stablecoin for invoices

Altitude supports USDC and EURC. USDC is a US dollar stablecoin issued by Circle, backed one to one by reserves. EURC is a euro stablecoin, also issued by Circle and backed one to one.

Invoice in the currency your customer wants to pay. USD invoices can be paid by ACH, wire, or USDC on a supported network. EUR invoices can be paid by SEPA or EURC on Solana. Altitude accepts EURC on Solana. Don't accept other stablecoins. Altitude credits only USDC and EURC to your account.

Matching USDC payments to your invoices

For example, a payment arrives and the amount is close to an open invoice but not exact. Guessing which invoice it settles creates a reconciliation error you'll discover at month-end.

Managing USDC value shifts on invoices

Circle designed USDC to hold a 1:1 value with USD, backed one to one by Circle's reserves. For current reserve composition, see Circle's reserve page.

For accounting, record the USD value at receipt. Your accountant handles any gain or loss if the value shifts between receipt and conversion.

Recovering USDC sent via unsupported chains

Altitude credits only USDC and EURC to your account, and any other token sent to your deposit address is permanently and irrecoverably lost. Before you share a deposit address, confirm the customer is sending USDC or EURC on a supported network: Solana, Ethereum, Base, Avalanche, or Tempo. State the network explicitly on the invoice. If a customer sends USDT, DAI, or any other token, the funds are gone.

Getting those four decisions right turns USDC from a one-off customer request into a repeatable receivables process. The immediate difference shows up at month-end: fewer unmatched deposits to chase, and a payment rail available to customers your current bank transfer setup cannot serve.

Do I need a crypto license to accept USDC?

Licensing requirements for accepting stablecoin payments vary by jurisdiction and sector, and Altitude can't answer that question for your business. Altitude is a financial technology platform, not a bank or digital asset custodian, and Altitude handles the account infrastructure. If you operate in a regulated industry such as financial services or payments, consult local legal guidance before accepting stablecoin payments. See terms of service for platform scope.

What happens if a customer sends the wrong token or uses an unsupported network?

If the customer sends USDC on a supported network, such as Solana, Ethereum, Base, Avalanche, or Tempo, it credits as USDC on Solana, typically within about 15 minutes. Any other token, including USDT or DAI, sent to your deposit address cannot be recovered. Stablecoins sent on the wrong network cannot be recovered. State the token and network explicitly on every invoice.

How long does USDC settlement take?

USDC on Solana settles in seconds. USDC sent on Ethereum, Base, Avalanche, or Tempo typically credits as USDC on Solana within about 15 minutes. For comparison, ACH settles in up to 3 business days and SWIFT in up to 5. Stablecoin transfers settle outside banking hours, including weekends.

Can I accept USDC without converting to fiat?

Yes. Balances are held in fully reserved stablecoins, backed one to one by the issuer's reserves, controlled by your business and not lent out by Altitude. You can receive USDC, hold it as USDC, convert it to EURC, or fund local payouts in GBP, MXN, BRL, or COP without converting to fiat first. Local payouts need workspace enablement before first use.

What are the tax implications of accepting stablecoins?

For US federal tax purposes, the IRS treats virtual currency as property: a taxpayer who receives virtual currency in payment for goods or services must record the USD fair market value at the date of receipt, per IRS Notice 2014-21. Notice 2014-21 predates stablecoins. Altitude's accounting sync posts transactions to QuickBooks Online with your confirmation. This is general information, not tax advice.
