I helped our accounting team set up an integration between monday and Xero. This was the only solution I found that was very easy to set up from the beginning and actually keeps things reliably in sync between the two platforms. We have projects spread across multiple orgs and this integration handles that perfectly. We have our existing flows in monday and when the team needs to create or update invoices or contacts in Xero, they can do that without leaving monday (finally!). I was particularly impressed with the how the integration handled historical items. We had over 20 thousand invoices, bills, and contacts already in Xero and this integration quickly imported them and continues to keep them up to date. Their customer support is excellent, usually responding within minutes if we have a question about configuration or a new feature we needed. Thank you!
