As answered by people managing RielSync and XE.com.
RielSync's answer
Most exchange rate tools give you a number and leave the rest to you. RielSync completes the job. It watches the official National Bank source, picks up each rate as it's published rather than on a fixed schedule, and writes it directly into the system your finance team actually works in. It's built around one specific problem rather than being a general currency API you have to wire up yourself.
RielSync's answer
Most exchange rate services supply the market rate, which moves constantly through the day. That's the right number for trading and the wrong number for accounting. Businesses are expected to book transactions at the official rate set by the National Bank of Cambodia, so a market feed leaves you reconciling against a figure your auditor won't recognise. RielSync settles on the official published rate, which is the one your accounts are actually measured against.
The second difference is scope. A currency API supplies data and leaves the integration work to you. RielSync completes the job, with prebuilt connectors for Odoo, SambaPOS, QuickBooks Online, Zoho Books and SAP Business One, plus a public API if you'd rather pull the rate into your own applications. Nothing to build, and nothing left for someone to type in each morning.
RielSync's answer
Finance and operations teams at small and mid sized businesses operating in dual currency environments, where the official rate has to be reflected accurately in the books every day. Typically the person who currently does this by hand, and the manager who has to correct it when it goes wrong.
RielSync's answer
RielSync came out of implementing ERP and POS systems for businesses operating in two currencies. The same problem appeared every time: someone opening the central bank page each morning, copying a number and typing it into the system, with the inevitable gaps whenever they were away or busy. It was small enough that nobody prioritised fixing it and persistent enough that it kept causing reconciliation work. So it got built.
RielSync's answer
RielSync is built with Next.js and React, written in TypeScript throughout and deployed on Vercel. Account and connection data sits in Postgres, hosted on Neon and accessed through Drizzle ORM, while rate history and delivery records are stored in Cloudflare R2. The codebase is tested with Vitest.

Like Wise, XE is very focused on online transactions. So this is best for those who want to perform quick online transfers without personal support from a representative.
