Auto-sync ClickFunnels sales into QuickBooks Online

Once a day on a schedule (a daily cron trigger), sync new paid ClickFunnels sales into QuickBooks Online so my books stay current without any manual data entry.

Start by pulling new paid orders from ClickFunnels with List Orders. Sort newest first and only consider orders that are marked paid. Keep track of the highest order id you have already synced (a watermark) and only process orders newer than that, so nothing gets synced twice. If an order has already been synced, skip it.

For each new order, match the buyer to an existing QuickBooks customer by email using Query Entities. If you find a confident single match, use it. If there is no match, create the customer with Create Customer using the buyer's name and email. If the match is ambiguous (multiple candidates, or a name that clearly does not line up), do not guess: flag it for manual review instead.

Record the sale as a Sales Receipt (not an invoice) with Create Sales Receipt, because funnel orders are paid immediately at checkout. Map each order line item to the matching QuickBooks product or service item by looking it up with Query Entities. When a line item cannot be matched to an item confidently, post it against the default income account I specify below. Map the order's line-item amounts and totals onto the receipt, and handle sales tax the way I configure below.

Never create a bad or duplicate record. When a customer or a product cannot be matched confidently, add that order to a manual review list with the order id, the buyer, the amount, and the reason it needs attention, rather than creating a guessed record.

At the end of each run, email me a short summary with Gmail using Send a Message: how many sales receipts were created, the total amount synced, and anything that needs my attention (orders skipped, customers or products flagged for manual review, and any errors).

Let me set three things: the default income account to use for line items that do not match a QuickBooks item, how sales tax should be handled (for example apply a specific tax code, record the order's tax as a separate line, or ignore tax), and the email address that receives the end-of-run summary.
