Yes. You can order from several suppliers in one checkout and pay Ordentic once.
Cart items are grouped by supplier. You can change the supplier on a line, or leave the choice open so any supplier can fulfill that line. Price optimization looks for strong combinations using cheapest and fewest deliveries (amounts excluding VAT). You can apply a suggestion, ignore it, or lock suppliers you want to keep.
After you pay, you get one order with a section per supplier. Each supplier ships their own part and uploads their own invoice under invoices on the order.
