Rush citation for service
I had a rush citation that needed to be served and called One Source to give them a heads-up that a document would be coming down the pike. They immediately sent me a welcome email, with all the information I had given them over the phone and said they would be waiting for further instruction from me. When I turned the document over to them, they notified me of attempts and success of service. This is the first time I had used them - they are a great company, which I highly recommend.
Superb process from start to finish. Quick communication and very informative!
Came through for us and we were up against a tough deadline.
Well done and I would highly recommend.
It was a great experience compared to the competition. The apostilled document was delivered in a timely manner & great communication. The only set back was that the translated document was not prepared even though it was paid for. Later I contacted One Source, they apologized for the inconvenience and the document was delivered by email.
I will do business with them again.
Pricing was clear, apostilled documents done on time, in fact earlier than expected. Suggestions given when one Federal document couldn't be obtained as needed.
Brandon and his team at One Source Process were a pleasure to work with! They exhibited excellent communication, completed service attempts quickly, and kept us updated throughout the process. Their professionalism and responsiveness made coordinating several difficult serves a smooth experience. We appreciate their assistance and would be happy to work with them again!
Amazing Service and Outstanding Customer Experience
We've been collaborating with One Source Process for over a year now, and it's always been a great experience. Kristen, Nancy, and David are always incredibly helpful, responsive, reliable, and patient. They guide you through the entire process and make sure your documents are notarized and apostilled correctly and on time. Thank you all for your amazing service and outstanding customer experience!
They do what they say including giving updates along the way. We were on a tight timeline and they came through! It was a great experience and hopefully, will not need their services again but, if we did, we would certainly return here. Thank you so much!!
One Sources Process is the only company I use when I need documents apostilled. They are always helpful and diligent. They contact you right away if there are any issues to address. I recommend One Source for all notary and apostille services.
