The End of Manual Data Matching

Open Supply Hub’s API checks your supplier data, removes duplicates, and saves you time to do what matters most in your organization.

You want a supplier database that is clean, reliable, and duplicate-free - but you have to spend hours comparing Excel spreadsheets to make it happen, taking time away from the impactful work you were hired to do.

  • Maybe you work for a company, getting ready to comply with increasing ESG requirements, and fear that you won’t be able to get a clean supplier database in time.
  • Or maybe your company provides supply chain mapping services and you know that the quality of your data is key to your competitive advantage.
  • Or you might be working for a civil society organization or a multi-stakeholder initiative and the numerous hidden duplicates in your database make it difficult to run cross-sector projects or facilitate access to remedy.

Regardless of the organization you work for, you know that you need to automate the inspection and deduplication process of your supplier data, or it will continue to consume your time and create problems in your organization.

You may be pondering some critical questions:

  • Can an automated process really be as good as doing it by hand?

  • Can it make keeping up with tough due diligence rules a bit less overwhelming?

  • Will it cut down on the repetitive task of comparing data, so I can concentrate on the more important issues?

  • Will it fix our customers' gripes about our too-small supplier data pool?

  • And, can it save me from the hassle of contacting each member to check if they source from a certain facility?

The answer is a resounding yes.

Open Supply Hub's API connects you directly to the same comprehensive database showcased on the Open Supply Hub website.

This grants your organization access to detailed information on hundreds of thousands of facilities, including their location, processing capabilities, product types, workforce size, and a list of other contributors utilizing these facilities.

The OS Hub API will do the heavy lifting for you:

  • Got the wrong name for a facility? It suggests a better one.
  • Address not quite right? It suggests the best match.
  • Stumbled upon duplicates? It merges them and gives you one unique ID you can share with your customers or display on your compliance reports.

The best part? You just saved hours of manual work.

Open Supply Hub’s API is your shortcut from spending endless hours manually checking datasets, to having everything done automatically.

  • If you work for a company, imagine the API correcting your supplier names and addresses, spotting and merging any duplicates, and even throwing in extra bits of info, like GPS coordinates or number of workers. You will impress compliance authorities by showing them you have a detailed overview of your supply chain.
  • If supply chain-related services are your company's specialty, your and your clients' data will integrate effortlessly with OS Hub's extensive database, delivering higher quality data and revealing previously undiscovered insights. It is a chance to broaden your offerings with just one easy integration. Plus, think of the edge you will give your clients by highlighting potential cost-effective partnerships, by identifying who else is sourcing from the same vendors.
  • Involved with a civil society organization or a multi-stakeholder initiative? By adopting OS Hub's API, you gain the ability to quickly sift through your database and find the right stakeholders for any project, or to accelerate finding solutions. Simplicity at its best.

Frequently Asked Questions
