What if Zoho shows an invoice as unpaid after Skydo has received the payment?

Compare the exact invoice and payment in both systems. Check invoice number, client, currency, amount, and whether the payment has been linked to that invoice in Skydo. A payment against another invoice or only part of the balance can make the status misleading.

The corresponding Zoho invoice is updated when the matching payment is received. If that has not happened, give support the invoice number, payment reference, current statuses, and when the receipt occurred. Do not create a manual payment entry in Zoho until you know whether a sync update is still pending, or you may count the receipt twice. Recheck both records once support confirms the correction.
