Commercial waybill for 3D printing: when you need one and what goes in it

An invoice locks in the price, a contract locks in each party's obligations — but confirming exactly what and how much shipped from you to the customer is a separate job. That's what a commercial waybill is for. Here's when you need one and what belongs in it.

When you need a waybill, and when you don't

If you hand the finished piece to the client in person or mail a single package, a waybill usually isn't necessary — an invoice or receipt is enough. It becomes necessary when:

• you're shipping a batch of items through a freight company or courier service;
• the customer is a business that needs to book the goods into their own inventory or accounting;
• quantity and item breakdown matter for downstream tracking (for example, the items are being resold).

How a waybill differs from an act

An act closes out a service — it states "the work is done, no complaints." A waybill closes out a shipment of goods — it states "here's exactly what and how much was shipped." If the order is finished items (say, a batch of miniatures or parts for resale), you need a waybill. If the order is a service (printing from the customer's files, reworking a model), you need an act. Sometimes you need both: a waybill for the items themselves and an act for related work like post-processing or painting.

What belongs on the waybill

Use a standard, unified waybill format rather than inventing your own — a custom format is harder to defend to auditors and unfamiliar to the customer's accountant. A waybill typically includes:

• supplier and consignee — both parties' registration details;
• item breakdown — name of each item (model, material, color);
• quantity and unit of measure;
• unit price and line total, plus the grand total;
• the total written out in words — a field specific to waybills, unlike an invoice;
• signatures confirming who released the goods and who received them.

Claims on quantity and quality

Worth stating explicitly, either on the waybill itself or in the contract: the customer must raise any claim about quantity or visible defects immediately on receipt, not weeks later. That protects you from a piece being used for a while and then returned as "defective."

How this works in the app

The waybill template in the Documents section already covers all the required fields — the item breakdown can be pulled straight from the order, and the total-in-words is calculated automatically. See the live editing demo in the general article on documents for 3D printing.
