I need a reliable, bi-directional link between Zoho CRM, Zoho Books and MYOB so data never needs to be typed twice. Standard fields are fine—no custom mapping—yet customer records, invoices (with line items, taxes, payments) and sales orders must stay perfectly in sync whichever system is updated first. You can draw on Zoho Flow, Deluge scripts, the Zoho Books and MYOB AccountRight APIs, webhooks or another middleware you trust; the only non-negotiable is that the process runs automatically and logs any errors so I can spot issues quickly. Deliverables • Integration architecture and tool selection • Configured connections covering customers, invoices, and sales orders in both directions • Duplicate-handling and error-logging rules in place • End-to-end test confirming that adds, edits and deletes travel correctly across all three apps • Brief hand-over notes so I can maintain the workflow without you If you have live examples of Zoho ↔ MYOB or multi-app accounting syncs, that will help me choose faster.
