I love the app, it's so easy to use and means I can talk to them at any time, day or night (often night when you have babies!)

Osome is reasonably priced and very convenient. I ended up signing my documents while I was on the tube!

Randeep Sudan

I set up a business and was getting bogged down in the admin. Osome has taken this all away from me. Osome is Awesome!

Dave Wallace

Everything was so seamless, it even looked like a fraud 😀 I didn’t have to go anywhere, I just use the web and mobile app to sign the docs.

Ivan Zeljkovic

I’m actually surprised they kept all their promises! I found Osome on Friday and on Monday morning everything was ready.

  • How many bookkeeping transactions do your packages include?

    We have flexible plans depending on the number of transactions each business has. A transaction is any deposit into or withdrawal from the bank. This way you only pay for the real work done.

  • What bookkeeping software do you use?

    We have our own platform that customers can access from a desktop or mobile device. They can send the docs easily, have their files stored and sorted out, and ask questions 24/7. We are integrated with Xero — an elegant accounting solution for small and medium businesses used by 2 million clients worldwide. Osome is Xero's platinum partner and an approved app. The migration takes just a few minutes and we make it happen ourselves.

  • How does outsourcing bookkeeping to Osome work?

    We collect all supporting documents and categorise them into corresponding accounts. Every day we connect to Xero and the clients’ banks to reconcile incoming documents with transactions. If a document is missing, we reach out to the customer on the same day. This way your Accountants won’t have to wait for the books to be ready at the end of the month: you can always rely on the data we provide.

  • How do you provide bookkeeping for a small business? What will it be like for my customer?

    Your customers will send us their receipts and invoices in any format they have them, like emails, scans or phone pictures. If anything is amiss, Osome platform highlights the transaction and sends a notification straight away. Your customers won’t have to spend hours at the end of the month trying to find long-forgotten documents.
