Manufacturing and Wholesale A/R: How to Get Paid Faster

Manufacturers, packaging suppliers and wholesalers rarely lose money to customers who refuse to pay. They lose it to invoices that fail the customer’s matching process, to short payments nobody disputes in time, and to hundreds of small accounts that never get a follow-up call. The fix is follow-up that confirms each invoice is in the customer’s system, resolves deductions while the evidence is fresh, and covers the long tail of small accounts as consistently as the big ones.

Manufacturing typically runs 45 to 60 days of DSO, according to Credit Pulse’s DSO by industry benchmarks, and 43% of US B2B invoice value was overdue in 2025 (Atradius, 2025). For a business that has already paid for raw materials, labor and freight before it invoices, every extra week of DSO is working capital tied up on the customer’s side of the ledger.

This page covers how industrial manufacturers, packaging and building materials suppliers, food and beverage producers, and wholesale distributors actually bill, where those invoices get stuck, and how follow-up should work for their buyers.

Most invoices in this group are tied to a purchase order and a shipment, and the customer will not pay until the three line up. That simple rule creates most of the delays.

PO-based invoicing and three-way match

The customer’s accounts payable team compares your invoice with its purchase order and its own receiving record. If the PO number is missing, the quantity differs, or the unit price does not match the PO, the invoice goes into an exception queue. It is not rejected and it is not paid. It just waits, often without anyone telling you.

Partial shipments and backorders

A single order can produce several shipments and several invoices. When one shipment arrives short or late, the customer may hold every invoice on the PO until the order is complete, which turns one problem line into a frozen balance.

Supplier portals and EDI

Larger customers want invoices submitted through a supplier portal or EDI rather than by email. An invoice emailed to a general inbox, or uploaded with the wrong reference, may never enter their payment run. Confirming that the invoice is in their system is the most useful first step in this industry.

Many small accounts beside a few large ones

Most manufacturers and wholesalers have a handful of large customers and a long tail of small ones. The large accounts get attention. The small ones age quietly, and together they can add up to a meaningful share of the receivable. Our guide to manufacturing A/R for many small accounts covers how to keep that tail moving without adding headcount.

Most late manufacturing payments are matching problems, not cash problems. The customer has the money. The invoice has not cleared their process yet.

Deductions and short payments

Customers take deductions for shortages, damaged goods, pricing differences, late delivery or promotional allowances, and pay the rest. Each deduction is small, the evidence (proof of delivery, the price agreement, photos) is scattered, and the window to dispute it closes quickly. Unresolved deductions turn into write-offs by default. Our guide to customer deductions and short payments walks through how to sort valid from invalid ones.

Big orders and long terms

Large orders often come with longer terms, and the biggest customers are often the slowest payers. A single large invoice that slips by two weeks can move the whole month’s cash position. For the playbook on those accounts, see getting paid on big orders in manufacturing and distribution.

Silence after shipment

Once the goods ship, the sales rep has moved on and the customer’s receiving team has filed the paperwork. If nobody confirms the invoice was received and matched, the first sign of trouble is the aging report at day 45.
