How the work actually runs.
Operational guides for the parts of logistics that are easy to describe and hard to run: unpaid duty at the door, returns across client brands, and the manual steps that quietly set the cost base.
Customs operations
DDU, DAP and DDP: who pays the customs bill when the parcel reaches the door
What actually happens when a recipient owes duty, what it costs the operator when they refuse, and how to collect the charge before the parcel moves.
Customs operations
How accurate is AI HS code classification — and how would you know?
What the published benchmarks actually show, why "over 80% accurate" is an incomplete claim, and how to test a classifier on your own declarations.
Returns operations
Returns management for 3PLs: what breaks when the second client signs
Running returns for several client brands is not the same problem as running them for one. What has to be configurable, and where the manual work accumulates.
Integrations
Carrier integration API: what one endpoint abstracts, and what it leaves to you
A multi-carrier API removes credential handling and format translation. It does not remove the carrier differences that cause integration projects to overrun.
Commercial operations
3PL billing software: from warehouse activity to an invoice nobody disputes
Most 3PL billing problems are evidence problems, not pricing problems. Why the invoice never matches the warehouse, and what to capture first.
Need this handled by software rather than a process document?
Duty and tax collection, returns and carrier integration are modules in the ByLogic platform. Book a free review and we will map which part of your current workflow they replace.

Written for the people who have to run it.
Most logistics software content explains the category. This section covers the operational detail that sits underneath it: what happens to a shipment between the moment a customs charge is raised and the moment the parcel is released, who carries the cost when a recipient will not pay it, and which manual steps quietly set the cost base of a returns operation.
Each guide is written for operations, customs and finance teams at courier companies, fulfilment providers, freight forwarders and cross-border retailers — the people who own the process rather than the budget line. Where a claim depends on a rule, a threshold or a carrier policy, the source is linked so you can check it against your own lanes and agreements rather than take our word for it.
We publish when there is something specific to say. There is no editorial calendar to fill, and no article here exists to rank for a category term we do not serve.
