How should I add several existing invoices to Skydo?
Keep each invoice as a separate, clearly named document with its own invoice number. Add the invoices through the options available in your account and check each client, amount, currency, and payment link before moving to the next one.
Do not upload several invoices as one combined sale just to reduce the number of uploads. If you have a large set to transfer, ask support which import method is currently available. If you use the supported Zoho connection, check its invoice coverage before uploading the same invoices manually. Keep a simple list of what you have already added so a retry does not create duplicate records. Review the final invoice list against that checklist.
