Acumens Deposits and Prepayments Management

Acumens Customer Deposits & Prepayments Management helps businesses handle deposits and prepayments without leaving Microsoft Dynamics 365 Business Central or Dynamics NAV. It also makes Accounts Receivable and Payable reporting easier to manage. Business Central doesn't let you take a deposit at the quote stage on its own. This app adds that. You can accept a deposit before a quote even becomes an order, and it won't touch your inventory. It also lets you set up a deposit on the whole sales order at once, instead of doing it line by line. You can choose a percentage or a fixed amount, whichever fits. The same works on the purchase side. You can set deposits on purchase orders the same simple way. And if you're dealing with a vendor across several purchase orders, you can group them into one deposit request instead of handling each separately. Sales deposits work the same way; you can combine several orders for one customer into a single request. You don't even need an order or quote first. You can just specify the item, fixed asset, or resource directly. Payments are covered too. It supports e-commerce and point-of-sale transactions, ACH, card-present and card-not-present payments, EMV chip & PIN, and contactless options like Apple Pay and Google Pay. For reporting, you get a clear view of deposits, what's invoiced, what's been paid, and what's still unused, by customer. There's also aged receivables reporting, broken down by how overdue each balance is. That gives finance teams a real-time read on cash flow instead of piecing it together by hand. If your team is already on Business Central and tired of managing deposits outside the system, this keeps everything in one place.
