Currency converter guide
Multi-Currency Converter
Move from base pricing to local totals with confidence. Choose cached rates for fast conversions or manual rates when a client has locked pricing.
Intro & Guide
The multi-currency converter is designed for fast, confident pricing. Enter an amount, choose the source and destination currencies, and review the conversion instantly. Pair it with the Invoice Generator, Tax/VAT Calculator, Email Sender Tool, or the QR Code Generatorwhen you need to deliver a complete quote. If you need more guidance, the full help guide walks through each step.
Use cached rates when you need quick estimates. They are stored locally and can be updated any time from the rate table so you can keep preferred values for repeat work. For negotiated pricing, switch to manual rate mode and enter the exact exchange rate you want to use.
The breakdown panel highlights the applied rate and the reverse rate, which makes it easy to verify the math before you send a quote or invoice. Review the conversion breakdown and adjust rounding when totals need to be precise.
Features & Use Cases
Use this currency converter when pricing services for international clients, validating cross-border invoices, or planning travel budgets. You can convert in either direction and swap currencies with one click.
Cached rates are ideal for quick estimates, while manual rates keep contracts aligned with agreed pricing. The converter stays flexible so you can handle last-minute changes, updated supplier quotes, or offline currency tables without leaving the page.
When sharing numbers with clients, confirm the rounded output with the built-in display helpers in the rounding guide to avoid confusion.
Rate Sources & Workflow
Start by choosing whether you want cached or manual rates. Cached rates are stored locally and provide a quick baseline for estimates, while manual rates let you lock in a specific number for client contracts.
If you are updating cached rates, choose the rate basis that matches your source. You can store values as 1 USD = currency or 1 currency = USD and the converter will handle the math correctly.
Use the rate table to enter the values your team trusts. The tool will reuse them in future sessions, making recurring conversions faster.

Educational Article
Exchange rates move constantly. For estimates, you can rely on cached values, but for contracts and invoices, confirm the rate you and your client agree on. A simple way to reduce confusion is to document the rate used alongside the final total.
Always review the reverse rate to ensure the conversion is sensible. If a value looks off, swap currencies or adjust the manual rate until the total matches your expected pricing.
Rounding matters when totals are large or when taxes are calculated later. A consistent rounding policy keeps invoices clean and reduces back-and-forth with clients in different regions.
