InvoiceQuickly + Wise: International Invoices at the Real Exchange Rate
International invoicing means currency conversion — and banks charge 3-5% hidden margins on exchange rates. Wise integration lets your clients pay invoices in their local currency while you receive the real mid-market rate, saving both parties money.
How It Works
Connect Wise Business account
Link your Wise Business account to InvoiceQuickly to access multi-currency receiving accounts.
Invoice in any currency
Create invoices in your client's currency. InvoiceQuickly shows the equivalent in your home currency at the live mid-market rate.
Client pays locally
Your client pays to your Wise local receiving account — no international wire fees for them.
Receive at mid-market rate
Wise converts at the real exchange rate with a small transparent fee (typically 0.4-0.7%), far below bank margins.
Key Benefits
- Real mid-market exchange rates — save 3-5% compared to bank transfers
- Local receiving accounts in 10+ currencies (USD, EUR, GBP, AUD, etc.)
- Clients pay as a local transfer — no SWIFT fees or correspondent bank charges
- Transparent fee structure with no hidden margins
- Multi-currency balance for holding funds in different currencies
Best For
- Freelancers billing US clients from the UK/EU (or vice versa)
- Agencies with clients in multiple countries needing low-cost international payments
- Consultants who invoice in the client's currency to avoid conversion pushback
Setting it up
Setup takes 5-15 minutes depending on whether you have an existing Wise account. Prerequisites: active Wise account with admin access, your InvoiceQuickly workspace, and the relevant API permissions or OAuth authorization. From Settings → Integrations → Wise, follow the connection flow (OAuth for most, API key for some specialized tools). The integration syncs bidirectionally where supported — invoice creation in one system reflects in the other. Initial setup includes mapping data fields between systems (customers, products, payment methods, tax codes).
Best practices
Define one source of truth for customer data
When you connect Wise, decide which system owns customer records. Most teams keep their primary CRM/ERP as the source of truth and let invoices sync into it. This prevents duplicate customer creation and reconciliation issues.
Test with a small batch before production rollout
Before syncing all historical data or going live for daily operations, test with 5-10 invoices to verify field mapping, tax handling, and payment workflow. Adjust configuration based on test results.
Reconcile sync status weekly
Network failures, OAuth expirations, and edge cases occasionally cause sync gaps. A weekly reconciliation (compare invoice counts in both systems) catches issues early before they accumulate.
Document the integration scope for your team
Write a brief internal doc (one page) covering: which workflows use the Wise integration, who owns reconciliation, what to do when sync fails. Reduces support overhead as the team grows.
Common issues
Sync stops after working initially
Most common cause: OAuth token expired (typically 60-100 days depending on the Wise platform). Reconnect via Settings → Integrations → Wise. Set a reminder to refresh authorization every 60 days for critical integrations.
Field mapping creates duplicate or missing data
During initial setup, the field mapping between Wise and InvoiceQuickly may not catch every edge case. Adjust mapping in Settings → Integrations → Wise → Field Mapping. Re-sync affected records after fixing.
Rate-limit errors during high-volume operations
Wise APIs typically allow 100-1000 calls per minute. Bulk operations (importing all customers, syncing 1000+ historical invoices) can hit rate limits. InvoiceQuickly handles backoff automatically; if you see persistent errors, retry during off-peak hours.
