The root cause is data fragmentation across multiple tools, and each change risks creating confusion about which version is current. The fundamental solution is to centralize inquiries, quotations, and orders in a single system, creating a version snapshot each time you send. To confirm what the other party changed, you can directly compare the two versions using a diff view instead of manually comparing email attachments. In practice, when starting the transition, we recommend beginning with the area most prone to errors—such as quotation version management—so your team sees immediate improvement and encounters less resistance. Then gradually bring other processes into the system. You don't need to swap everything at once; stabilize your core trading workflows first, then you'll have a foundation to expand on.
