Hello everyone,

We have a client requirement to automatically update currency exchange rates in Microsoft Dynamics 365 Business Central from an external source.

I am familiar with configuring the Currency Exchange Rate Service. The following public sources are being considered:

However, the client wants to understand the original source from which these providers fetch their exchange rates and how we can assure them that the rates are reliable and trustworthy.

For FloatRates, I found that source information is available only for certain currencies. It is not clear how all the remaining currency rates are sourced and validated.

As another option, we can integrate Business Central directly with an official bank or reference-rate provider. Since the implementation is for INR, I reviewed FBIL; however, only a limited number of currency exchange rates are available, and the published rates do not always appear to be up to date.

How do you normally address this requirement with clients? Is it acceptable to use public exchange-rate providers, or is direct integration with an official source the better approach? INR, USD, GBP, EUR

Please share your point of view. No AI-generated answers, please.

Hi, I run into the same problem in Canada with the Bank of Canada. Not all currencies are available.

There are really two main options.

1. Most commonly I just use float rates. Pretty much all clients I work with use this service. A big note about float rates. It updates the rates hourly, the last update is around 11pm GMT. So just make sure your job queue pulls in that final rate of the day (somewhere around 11:30pm GMT). I am in the pacific time zone so typically I set this to 4:30pm.

Also, you can create an account for float rates and pick a specific source and then weight those sources. For example I have a USD fx rate that looks at the bank of canada and european central bank:

2. Use a paid service such as Xe - Xe Business ERP Solution for Microsoft Dynamics 365 Business Central - then integrate it with Business Central.

Hope that gives you some ideas.

Best,

We typically use fee-based services provided by local banks; free services like the one you mentioned might suddenly become unavailable, and there are also issues with unsupported currencies. I suggest you try contacting a local bank.

Hello Khushbu,

For an INR-based company, I would recommend using FBIL as the reference source for USD/INR, GBP/INR and EUR/INR, because FBIL has officially computed and published these reference rates since 10 July 2018, and RBI itself displays them as sourced from FBIL. However, before automating directly from the FBIL website, the client should confirm licensing and obtain permission because FBIL states that commercial use of its website data is not authorised without written approval. Public aggregators can be acceptable for operational purposes only when they provide a documented methodology, identified upstream sources, contractual usage rights, availability commitments and historical auditability; otherwise, I would avoid using them for statutory or financial reporting. Business Central does not validate or certify the provider—it only allows an external exchange-rate service to be mapped and scheduled—so the provider selection remains a finance, audit and compliance decision. A practical approach is to use FBIL or a licensed provider that redistributes FBIL rates, store the source/date/time with each import, add validation against the previous rate, and require finance approval for unusual variances.

Regards,
Oussama Sabbouh
