Back Office for Custom House Brokers
ISF and entry data preparation, classification support, duty calculation and compliance records — prepared by a dedicated team for your licensed broker's review.
Customs brokerage back office outsourcing
Deadlines set by regulation, not by preference.
ISF is due before lading. Entry summary is due after release. Classification has to be defensible, duty has to be right, and the record has to be retrievable years later if CBP asks. None of those timelines flex because volume spiked or someone is on leave.
Infinity IPS provides the preparation and record-keeping behind that work — as a dedicated team inside your own system, assembling and validating so your licensed brokers spend their time on judgement rather than data entry. We have supported logistics back office operations since 1998.
Why brokers work with us
Volume handled without diluting licensed judgement.
The bottleneck in most brokerages is not expertise. It is the preparation time in front of it.
- ISF data prepared and validated ahead of the pre-lading deadline
- Entry data assembled and checked for your broker's review
- HTS classification research and database maintenance
- Duty, tax and fee calculation with supporting rationale
- FTZ admissions, transfers and inventory records
- Duty drawback claim compilation and matching
On licensed responsibility: our teams prepare, validate and maintain records. Every filing is reviewed and submitted by your own licensed customs broker, and classification determinations remain a licensed decision. We support the process — we do not replace the licence.
Entry, classification & duty
Prepared correctly the first time.
Most entry corrections trace back to something missing or mismatched at preparation. We assemble the data, check it against the commercial documents, and flag what does not reconcile before it reaches your broker.

Common questions
Customs brokerage back office, answered.
What does a customs broker back office cover?
ISF and entry data preparation, HTS classification support, duty and tax calculation, document collection and validation, bond and FTZ administration, duty drawback claim preparation, and compliance record maintenance for audit readiness.
Do you prepare entry data for licensed broker review?
Yes. Our teams prepare and validate entry data, assemble supporting documentation, and flag discrepancies — with every filing reviewed and submitted by your own licensed customs broker. We support the process rather than replacing licensed responsibility.
Can you support HTS classification?
We maintain classification databases, apply established rulings and precedent to repeat product lines, and prepare classification research for your licensed broker's determination. Novel or ambiguous classifications remain a licensed decision.
Do you handle duty drawback claims?
Yes. We compile import and export documentation, match exported goods to original entries, calculate recoverable duty, and prepare drawback claims for filing — including the record-keeping required to support them.
What about ISF filing deadlines?
ISF data is prepared and validated against the booking well ahead of the 24-hour pre-lading requirement, with missing elements chased from the importer or agent rather than discovered at the deadline.
Do you support customs audit preparation?
Yes. Entry records, supporting documents, classification rationale and duty calculations are maintained in an organised, retrievable form so a CBP request can be answered promptly rather than reconstructed.
