## Overview

Fixer provides reliable, real-time and historical foreign exchange rate data for 170+ currencies. Stripe handles payment processing and subscription billing for businesses of all sizes. When you connect them, finance and operations teams can dynamically price products, reconcile international transactions, and report revenue accurately across every currency their customers use. For any business serious about global payments, this combination is hard to work without.

Managing multi-currency transactions manually is one of the most error-prone and time-consuming tasks in global finance. Exchange rates move constantly, and without a live data feed, your Stripe charges, invoices, and revenue reports fall out of sync with the actual market rate. Connecting Fixer to Stripe through tray.ai lets teams automatically pull the latest exchange rates and apply them to Stripe pricing, subscription plans, and invoice line items in real time. No manual lookups, less risk of overcharging or undercharging international customers, and finance teams who always have accurate, current revenue data in the currency they report in. For SaaS companies, marketplaces, and e-commerce businesses with global customers, this isn't optional — it's how the billing stack has to work.

## Use cases

### Dynamic Multi-Currency Pricing for Stripe Products

Automatically update Stripe product prices based on the latest exchange rates from Fixer. Whenever a base currency rate shifts beyond a defined threshold, tray.ai triggers a workflow that recalculates and updates localized prices across all relevant Stripe Price objects. Your international customers are always charged the correct market-aligned amount, with no manual intervention needed.

- Eliminate manual price updates across dozens of currency-specific Stripe products
- Reduce pricing discrepancies that erode international margins
- Keep localized pricing accurate and competitive without the upkeep

### Real-Time Revenue Reporting in a Single Base Currency

Pull transaction data from Stripe and automatically convert foreign-currency charge amounts to your home currency using Fixer's historical or live exchange rates. This workflow feeds normalized revenue figures into your finance dashboards or data warehouse, giving your CFO a single source of truth for global revenue. Month-end reconciliation becomes a clean process rather than a spreadsheet nightmare.

- Produce accurate single-currency revenue reports without manual FX lookups
- Speed up month-end close by automating currency reconciliation
- Feed normalized data directly into BI tools or accounting software

### Automatic Invoice Currency Conversion for International Customers

When Stripe generates an invoice for an international customer billed in a non-base currency, tray.ai fetches the current exchange rate from Fixer and appends the converted amount as a memo or custom field on the invoice. Finance teams can immediately see both the local charge and the home-currency equivalent, which simplifies bookkeeping and customer dispute resolution.

- Reduce customer billing queries with transparent currency conversion details
- Simplify bookkeeping by capturing FX rates at the point of invoicing
- Support audit trails with rate data recorded at transaction time

### FX Rate Threshold Alerts for Stripe Revenue Risk Management

Set up automated monitors using Fixer rate data to detect when a currency pair moves beyond an acceptable threshold relative to your Stripe pricing. When that threshold is breached, tray.ai alerts your finance or revenue operations team via Slack, email, or a ticketing system, giving them time to review and adjust Stripe subscription or product pricing before revenue impact builds.

- Catch FX exposure early, before it shows up in recognized revenue
- Keep revenue operations teams informed of critical rate movements right away
- Reduce financial risk from volatile currency pairs

### Subscription Plan Localization at Renewal

For Stripe subscriptions billed in local currencies, automatically evaluate the current Fixer exchange rate at each renewal cycle and determine whether the subscription amount still falls within an acceptable range of the home-currency target price. If rates have drifted too far, tray.ai can trigger a price adjustment workflow or flag the subscription for manual review before the next billing date.

- Maintain target subscription revenue in base currency terms over time
- Automate renewal-time price reviews without engineering involvement
- Avoid sudden, large price corrections that drive customer churn

### Multi-Currency Refund Calculation and Processing

When a refund is initiated in Stripe for a transaction originally processed in a foreign currency, tray.ai uses Fixer to retrieve the exchange rate at the time of the original transaction and recalculates the refund amount in the home currency. Accounting entries stay accurate, and refunds are issued at the correct historical rate rather than whatever the rate happens to be today.

- Issue refunds at the correct historical exchange rate automatically
- Keep accounting accurate for foreign-currency refund entries
- Reduce manual work for finance teams handling international disputes

### Daily FX Rate Snapshot Storage for Stripe Audit Compliance

Automatically fetch daily exchange rates from Fixer for every currency you accept in Stripe and store them in a database, spreadsheet, or data warehouse. This builds a verifiable historical record that auditors can reference when reviewing Stripe transaction records, so your business can meet financial compliance standards for multi-currency revenue recognition without scrambling.

- Build a verifiable FX rate audit trail aligned with Stripe transaction history
- Meet revenue recognition compliance requirements for international billing
- Eliminate ad-hoc rate lookups during audits with a maintained rate archive

## Challenges Tray.ai solves

### Exchange Rate Lag Causing Mispriced International Charges

When Stripe prices are set manually in foreign currencies, they quickly fall out of step with actual market rates as currencies move. Customers end up overcharged or undercharged, and the resulting revenue leakage or customer dissatisfaction often isn't visible until month-end reconciliation — by which point the damage is already done.

**How Tray.ai helps:** tray.ai continuously polls Fixer for the latest exchange rates on a schedule you define and automatically triggers Stripe price update workflows whenever rate drift exceeds your tolerance threshold. Your Stripe prices stay market-aligned without any manual work from finance or engineering.

### Inconsistent FX Rates Used Across Invoice, Refund, and Revenue Records

Without a centralized rate source, different teams tend to use different rates for invoicing, refunds, and reporting, which creates reconciliation headaches and audit failures. A refund processed at today's rate may not match the rate captured at invoice time, leaving discrepancies in accounting records that are painful to untangle.

**How Tray.ai helps:** tray.ai standardizes all FX data by fetching rates exclusively from Fixer at defined workflow trigger points — invoice creation, payment capture, and refund initiation — and stamps each Stripe record with the rate used. That creates a consistent, auditable FX data trail across your entire billing lifecycle.

### No Historical Rate Data for Stripe Transaction Audits

Finance and compliance teams regularly need to verify what exchange rate was in effect when a specific Stripe transaction occurred. Without a systematic archiving process, teams end up manually hunting for historical rates, which takes time and is often inaccurate.

**How Tray.ai helps:** tray.ai automates a daily Fixer rate snapshot workflow that stores timestamped exchange rate data in your database or data warehouse. When auditors or finance teams need to verify a historical Stripe transaction, the rate data is already there and indexed, cutting audit preparation time significantly.

### Manual Multi-Currency Revenue Reporting Slowing Down Month-End Close

Consolidating Stripe revenue across multiple currencies into a single reporting currency is a painful manual process involving spreadsheet lookups, formula errors, and time zone mismatches. It routinely delays month-end close by days and introduces the risk of material reporting errors.

**How Tray.ai helps:** tray.ai automates the full pipeline from Stripe charge event to normalized revenue record by fetching the applicable Fixer rate in real time and writing the converted figure directly to your reporting system. Finance teams get a continuously updated, single-currency revenue view without touching a spreadsheet.

### Engineering Bandwidth Required to Maintain Custom FX-Stripe Sync Code

Many teams build in-house scripts to sync exchange rates into Stripe, but those scripts need ongoing maintenance, error handling, and monitoring. When they fail silently, pricing and billing errors can go undetected for days, creating real customer trust and revenue problems.

**How Tray.ai helps:** tray.ai replaces fragile custom scripts with no-code, monitored workflows that include built-in error handling, retry logic, and alerting. Finance and revenue operations teams can own and modify these workflows without engineering help, freeing developers to focus on product work.
