The invoicing tool you choose as a freelancer working with international clients affects more than just how your invoice looks. It determines how much of each payment you keep, how quickly you receive it, and whether the process creates friction for your client's finance team.
A client in New York paying via ACH expects to enter a routing number and click "send." A client in London expects a SEPA-compatible IBAN. A client in Dubai may want to pay by card. If your invoicing tool does not support the payment method your client prefers, the invoice sits unpaid while both sides figure out an alternative. And if the tool charges 3% to 5% per transaction in processing and conversion fees, you are losing $150 to $250 on every $5,000 invoice before the money reaches your bank.
This article compares six invoicing tools on the things that actually matter for international freelancers: pricing, transaction fees, multi-currency support, automation, and whether the tool integrates invoicing and payment collection into a single workflow.
Missing or incorrect payment details. A wrong IBAN digit, an outdated SWIFT code, or a mismatched account name causes rejected transfers. Always copy and paste account details rather than typing them, and verify with your payment provider before sharing.
Vague service descriptions. "Consulting services" tells a finance team nothing. "UX audit of checkout flow, 40 hours at $75/hour" tells them exactly what was delivered and how the amount was calculated. Vague descriptions delay approvals because someone has to ask what the charge is for.
No currency specified. If your invoice says "500" with no currency, the client may process it in their local currency, convert incorrectly, or send it back for clarification. State the three-letter currency code (USD, EUR, GBP) next to every amount.

Before choosing a tool, it helps to know what the tool needs to produce. An international freelance invoice should include: a unique invoice number, issue date and payment due date, your legal name or business name and address, the client's name and billing address, itemised services with descriptions, quantities, rates, and line totals, the total amount due in a clearly specified currency (USD, EUR, GBP), your preferred payment method with specific details (routing number and account number for ACH, IBAN and SWIFT/BIC for wire, or a payment link), and payment terms (Net 14, Net 30, or milestone-based).
Two elements are particularly important for cross-border invoices. First, the currency must be stated explicitly. An invoice that says "$500" without specifying USD, CAD, or AUD creates ambiguity. Second, the payment instructions must match the client's preferred payment method. If your client's finance team processes ACH payments and your invoice only includes a SWIFT code, the invoice goes to the back of the queue.
Pricing: Free. No subscription, no monthly fees.
Transaction fees: 1% conversion fee, capped at $6 per conversion. No per-invoice processing fee.
Multi-currency: USD, GBP, EUR.
Best for: Cross-border freelancers who want invoicing and payment collection in one platform.
Grey's invoicing tool is free and integrated with Grey's multi-currency accounts. This is the key differentiator: you create the invoice within Grey, the client receives a payment link, they pay via ACH (USD), SEPA (EUR), or Faster Payments (GBP), and the money lands directly in your Grey balance. There is no separate payment gateway, no third-party processor, and no additional processing fee per invoice.
The workflow: create an invoice in the Grey app or web dashboard, add your client's details and the line items, set the currency and due date, and send. The client clicks the payment link, pays via their local bank transfer method, and the funds are deposited into your Grey account. You convert to your local currency when you choose (a 1% fee, capped at $6) and withdraw to your local bank account.
Grey does not currently offer time tracking, project management, or recurring invoice automation. It is a focused tool: create, send, get paid. If you need those features, pair Grey with a time-tracking tool (Toggl, Clockify) or a project management tool (Notion, Asana).
Pricing: $19/month (Lite, 5 clients) to $33/month (Plus, 50 clients). Discounts of 50% to 70% often available for the first 3 to 6 months.
Transaction fees: Depends on the payment gateway. ACH: 1% ($1 min). Credit card: 2.9% + $0.30.
Multi-currency: Yes, supports multiple currencies.
Best for: Freelancers who bill hourly and need time tracking linked to invoicing.
G2 rating: 4.5/5.
FreshBooks is the strongest option for freelancers who bill by the hour. Built-in time tracking lets you log hours against a project, and those hours auto-populate into an invoice. The platform also supports automated payment reminders (FreshBooks reports that freelancers who use them get paid up to 11 days faster), recurring invoices for retainer clients, and expense tracking. The main drawback for international freelancers is the monthly subscription cost and the reliance on a separate payment gateway for processing, which adds per-transaction fees on top.
Pricing: Free (Starter). Pro plan: $16-$19/month.
Transaction fees: Credit card: 2.9% + $0.60. ACH: 1%.
Multi-currency: Limited.
Best for: Freelancers starting out who want free invoicing with basic accounting.
G2 rating: 4.3/5.
Wave offers free invoicing and basic accounting (income/expense tracking, simple financial reports) in one dashboard. It is the most accessible starting point for a freelancer who has never used invoicing software. The limitation for international freelancers is that multi-currency support is limited, and the 2.9% + $0.60 per credit card transaction adds up quickly on larger invoices. On a $500 invoice paid by card, you lose $15.10 to processing fees.
Pricing: Free. No subscription.
Transaction fees: 2.99% + $0.49 per transaction. FX conversion adds approximately 3% to 4%.
Multi-currency: Yes, 24+ currencies.
Best for: Freelancers whose clients already use PayPal.
G2 rating: 4.4/5.
PayPal's advantage is familiarity. Over 430 million accounts globally mean most clients already have one and can pay an invoice in seconds. The disadvantage is cost: the combination of the 2.99% transaction fee and the 3% to 4% FX conversion fee makes PayPal one of the most expensive options for international invoicing. On a $500 invoice, total fees can reach $30 to $35, or 6% to 7%. For occasional small invoices where client convenience is paramount, PayPal works. For regular large invoices, the fees are disproportionate.
Pricing: $9 to $15/month (Basic) to $19 to $25/month (Essentials).
Transaction fees: Credit card: 2.9% + $0.30. ACH: ~1%.
Multi-currency: Yes.
Best for: Freelancers who want contracts, proposals, and invoicing in one platform.
G2 rating: 4.7/5 (HoneyBook, similar category).
Bonsai combines proposals, contracts, project management, time tracking, and invoicing into a single workflow. You send a proposal, the client signs the contract, you track the work, and Bonsai generates the invoice from the agreed terms. For freelancers managing multiple international clients with ongoing relationships, this end-to-end workflow significantly reduces admin. The trade-off is the monthly subscription and per-transaction fees.
Pricing: Free.
Transaction fees: Depends on connected payment gateway (Stripe, PayPal, etc.).
Multi-currency: Yes, extensive.
Best for: Freelancers who want advanced automation without a subscription fee.
G2 rating: 4.6/5.
Zoho Invoice offers free invoicing with features that most competitors charge for: automated payment reminders, recurring invoices, client portals, multi-currency billing, and integration with the broader Zoho ecosystem (Zoho Books, Zoho CRM). The limitation is that payment collection requires connecting a third-party gateway (Stripe, PayPal), which adds its own transaction fees. Zoho is a strong choice if you want more automation than Wave but do not want to pay for FreshBooks.
This is the comparison that matters. Below is the total cost, including subscription (amortized monthly if applicable), transaction processing, and FX conversion, when a US client pays a $500 invoice.
Grey's cost advantage comes from the absence of a per-invoice processing fee. Most invoicing tools charge 2.5% to 3% every time a client pays by card, which is $12.50 to $15 on a $500 invoice. Grey charges nothing at the invoice payment stage because the payment flows directly into your Grey account via ACH, SEPA, or FPS. The only fee is the 1% conversion fee when you move funds to your local currency, capped at $6, regardless of the amount.
The trade-off is that Grey does not offer time tracking, project management, or recurring invoicing. If those features are essential, FreshBooks or Bonsai is worth the subscription cost. If your primary need is to invoice international clients and get paid without losing 3% to 7% per transaction, Grey is the lowest-cost option.

The value of invoicing software is not just in creating the invoice. It automates the steps around it, so you spend less time on admin and more time on billable work.
1. Contract or scope agreement. Before the first invoice, agree in writing on the scope, rate, currency, and payment terms. This prevents disputes later. Tools like Bonsai handle contracts and invoicing together.
2. Invoice creation. Use saved templates with your client's details, your payment information, and standard terms pre-filled. Creating each invoice should take under two minutes.
3. Automatic payment reminders. Set reminders for 3 days before the due date, the due date itself, and 7 days overdue. Most invoicing tools (FreshBooks, Zoho, Wave) automate this. If your tool does not, calendar reminders work as a manual fallback.
4. Online payment via the invoice. The invoice should include a payment link or button that lets the client pay immediately. Every extra step between "I approve this invoice" and "I've paid it" adds days to your payment timeline.
5. Payment tracking and reconciliation. Your invoicing tool should show you at a glance: total invoiced this month, total paid, total overdue, and total outstanding. This is your cash flow dashboard.
Choosing an invoicing tool depends on your location, client geography, payment needs, and how you want to manage billing, currency, and compliance across borders.
Choose a tool that supports how your clients prefer to pay and how you want to receive funds locally. Some platforms are better suited for US clients using ACH, while others support cards or global transfers. Also consider payout options such as mobile money, local bank accounts, or holding foreign currency. The right fit reduces friction, speeds up payments, and ensures you can access funds easily without relying on complex or costly workarounds.
A strong invoicing tool should allow you to invoice in your client’s currency while giving you control over when and how you convert funds. Look for platforms with multi-currency support and transparent exchange rates. Poor FX rates can quietly reduce your earnings over time. The ability to hold USD, EUR, or GBP and convert strategically helps protect your margins and gives you better financial control across international transactions.
Understand how the platform charges for its services beyond just monthly subscriptions. Some tools offer free invoicing but charge higher transaction or FX fees, while others have subscription plans with lower processing costs. Look at card fees, transfer charges, and withdrawal costs. A platform that appears cheap upfront may cost more in the long run, depending on your transaction volume and client payment behaviour across different markets.

The tool should meet regulatory requirements relevant to your country while remaining simple to use daily. Consider onboarding requirements, document verification, and how easily you can create and manage invoices. A complex system can slow you down, while a compliant and intuitive platform helps you operate smoothly. This balance is important for freelancers working with international clients who need both reliability and speed in their invoicing process.
1. What is the best way to invoice international clients as a freelancer?
The best approach is to use a digital invoicing tool that supports multi-currency billing and global payment methods. This allows you to invoice in your client’s preferred currency while receiving funds conveniently. It also improves professionalism, reduces errors, and speeds up approval and payment timelines.
2. Should I invoice in my local currency or the client’s currency?
It is generally better to invoice in the client’s currency to reduce friction and make payments easier for them. However, using tools that allow you to hold foreign currency helps you avoid poor exchange rates and decide when to convert funds based on favourable market conditions.
3. How can I reduce fees when receiving international payments?
You can reduce fees by using fintech platforms with low FX margins, consolidating transactions, and avoiding unnecessary conversions. Choosing ACH over SWIFT where possible and comparing platform charges regularly helps you keep more of your earnings from international clients over time.
4. Do I need a business account to invoice international clients?
Not always, but having a business account improves credibility, separates personal and business finances, and simplifies tax reporting. Many invoicing platforms also work better with business profiles, giving you access to more features and smoother payment processing for global freelance work
Managing international invoicing becomes easier when you use tools built for cross-border work. Grey stands out by combining multi-currency accounts with a free invoicing tool that lets you create, customise, and send professional invoices without added costs.
With competitive exchange rates, fast access to funds, and simple payment tracking, Grey helps you stay in control of your earnings. Sign up or download the Grey app today to manage payments globally.
