Light Assembly and Rework at a 3PL: Scope, Labor and Quality Checks

I treat light assembly and rework as a separate service line, not a footnote on a fulfillment quote. The scope has to be written down before I ask for a rate. For me, light assembly usually means kitting, inserting a card, applying a label, bagging, or putting two SKUs into one sellable unit. Rework is different: correcting a label, repacking damaged units, replacing a component, or inspecting a batch after a vendor issue. I ask the provider to spell out which tasks are included and which need a new quote.

A simple scope sheet keeps the conversation honest. I list the incoming condition, the finished condition, the expected units per hour, and who supplies materials. If a task needs a fixture, a printer, or a special bag, I note it. I also ask where the work happens: on the receiving dock, in a dedicated area, or inside the pick floor. That answer affects both speed and quality.

Labor rates need more than an hourly number. I ask whether there is a minimum block of time, a setup charge, or a rush premium. Say a plan quotes $28 per labor hour with a two-hour minimum. That may be fine for a small repack, but it changes the math for a 40-unit job. I get the rate in writing and ask how the provider tracks hours. I also ask who pays for scrap and whether materials are billed at cost plus a handling fee. Check the provider’s current terms, since these details vary.

QA signoff is where I spend the most time. I want a named person who approves the first piece, a sample check during the run, and a final signoff before units go back to stock. For rework, I ask for photos of the before and after condition and a clear disposition for units that cannot be fixed. I also want a short daily summary: units completed, units rejected, and open questions. When I compare providers, I use a consistent set of questions and sometimes start from a shortlist fulfillment services page to keep the comparison fair.

My rule is simple: if the scope, labor rate, and QA signoff are not clear, I do not approve the job.
