Standard invoices and partial billing: charging for the correct supply

An invoice establishes what the customer is being billed for and when payment is due. A standard invoice can follow delivered goods or, where appropriate, be entered directly. Sourcing delivery notes ties billing to fulfillment and reduces the risk of billing the same goods twice.

DNA STANDARD invoicing can select one or more delivery notes and inherit the lines. Direct invoices require the appropriate warehouse and stock checks. Source-order discounts may be locked and allocated proportionally on partial invoices. The due date is derived from the selected terms. The invoice's posting result and related ledger record must be checked separately; a saved form alone is not evidence of a successful accounting entry.

What an invoice needs to explain

An invoice should make the billed goods or services, quantities, prices, adjustments, and payment obligation understandable. Its relationship to the order or delivery helps establish why that amount is due.

Partial billing is useful when a commitment is fulfilled or billed in stages. It preserves the relationship to the larger agreement while recording only the amount appropriate to the current invoice. The sum of the parts must remain consistent with the agreed whole.

A proportional concession

A 100-unit order has an order-level concession of 200. When 40% of the qualifying base is invoiced, a proportional share would be 80, leaving 120 for the remainder in this simplified equal-price example. Giving the full 200 on every partial invoice would multiply the concession.

The proportional base matters. Forty percent of the quantity is not necessarily forty percent of the value if products have different prices. DNA's source totals and inherited calculation determine the actual allocation. The simple example assumes equal prices solely to illustrate the principle.

Why inherited values can be restricted

When an invoice comes from an existing sales agreement, some commercial values are inherited or locked. This helps prevent the billing team from unintentionally changing terms already established earlier.

An inherited discount is part of that agreement. Applying another unrestricted discount at every partial invoice can create a commercial result nobody intended. The final invoice may also reveal rounding differences accumulated across earlier parts, so the overall order position matters as well as the current document.

Direct and delivery-based invoicing

Delivery-based invoicing explains the billed supply through existing delivery records. Direct invoicing serves situations where the supported process does not begin from those records. DNA applies the relevant warehouse and stock checks to direct standard invoices.

The business should understand which operational event the invoice represents. Treating a direct invoice as though stock had already been handled elsewhere can create a misleading interpretation of fulfilment.

Issued, posted, and paid

The invoice's approval and posting position explain its system effect. Its settlement position explains what remains unpaid. Posting concerns the accounting record, while collection concerns settlement. Evidence of the posted entry does not establish that the customer has paid.

The reliable view connects the invoice to its source, its calculated total, its posting evidence, and its allocations. That connection allows finance to explain both what was charged and what remains collectible.
