The sea gateway

Software for a Karachi sea desk

Nearly all of Pakistan's sea freight moves through Karachi, which means a Karachi forwarder's day is not the generic freight-forwarding day the software brochures describe. It is an IGM, a rotation number, a berth, a stack, a delivery order and a detention clock. This page is about whether those boxes exist on the screen.

Sea import and sea export, both directions Container grid with CRO, detention and empty return Per-container invoicing in up to three currencies 150 report screens

A note before the detail. Cargonio is software, sold and supported from one place across Pakistan. There is no branch in this city, nobody sits in it, and no customer of ours is named here as being in it. What follows is about the screens.

The working day

A sea import, from the manifest to the empty return

The order below is the order the screens are built in, because it is the order the file actually moves through an import desk.

01

The line files its IGM

Manifest Inbond Shipments (Sea-Import) is a short field set keyed straight off the line's manifest, before anyone has a full file. It is a separate screen from the job on purpose — a manifest record can never be opened as an inbond job, and an inbond job never appears on the manifest list.

02

The file becomes a job

Inbond Shipment Entry and Documents Printing (Sea-Import) carries the MBL and the HBL as two separate blocks, each with its own number, date, PP/CC, pieces, UOM, CBM and weights — plus a Total of HBL block that adds the house rows up for you.

  • Vessel, Voyage, Rotation No, ETD, ETA, Arrived Date
  • LCL / FCL and CY / CFS
  • Party Code, Sub Agent Party, S/Line Agent, Delivery Agent, Clear Agent
03

Berth, stack and yard

The routing block goes past origin and destination into the boxes an import clerk keys after the vessel is alongside.

  • Shed, Terminal and Wharf
  • Stevedoring, Stack No, Stack Date, Stack Code, Berth No
  • Port of Shipment, Port of Loading, Port of Discharge, Via Port
04

Customs and the delivery order

One block holds every reference the clearance turns on, so nobody has to keep a parallel register.

  • IGM No and date, B/E No and date, Index No, Sub Index No
  • D/O No and D/O Issue Date, NOC Valid Date
  • Guarantee No, VIR Number, Cust Ref No, HS Code, Doc Rcv Date
05

Containers off the terminal

The container grid is a row per box, and it keeps going after the gate: the vehicle that lifted it, when it was due, when it actually arrived, and where the empty went back.

  • Container No, Size, Seal No, ISO Code, Pkgs, Weight, Net Wt
  • Vehicle No, Vehicle Date, Vehicle ETA, Vehicle ATA, Empty Location
  • CRO (Free) Date, Detention Days, Detention Amount
06

The detention argument

Free Days, Total Detention Days, Detention Rate / Day and Total Detention Amount sit on the job header above the per-container figures, which is what lets you answer a customer disputing a demurrage bill without reopening the file.

07

The line's security back

A Container Security schedule records each instrument you posted — instrument, number, date, amount — against Total Security Receivable and Balance Security Receivable, so what is still lying with a shipping line is a number rather than a memory.

Billing

Why the sea invoice is the hard one

Air freight prices off a rate and a weight. Sea prices off boxes, sizes, volumes and two or three currencies at once, and a generic invoice screen cannot do it. The four mode-bound local invoices carry a container-rate model instead.

🧱

Priced per container

A grid of No. of Containers × Container Rate, with the container size and TEU on the row. The sea-import screen adds a currency to each row of the grid — the source system's own behaviour, kept.

📦

LCL priced on volume

CBM and CBM Rate on the header. Freight is CBM × CBM Rate in the document currency, folded into the subtotal with the container freight.

💱

Three currencies on one invoice

Currency and Ex. Rate, then a second and a third pair. Each charge row converts at its own rate and the PKR sum is the authoritative one, so a line in a third currency stays exact instead of being averaged away.

🖨️

FRC and PKR freight, split for the print

FRC Freight and PKR Freight are separate boxes because the printed invoice shows them separately. They are presentation, not a second total.

🧾

Two charge grids, not one

Shipping-line charges and other charges are kept apart on the same document, each row with its own charge code, quantity, rate, currency and exchange rate.

⚖️

One line of arithmetic, everywhere

Grand total = subtotal + sales tax + PRA fee + provincial tax − withholding, and every figure is stored a second time in PKR at the document's own rate so the ledger never adds dollars to rupees.

The other direction

Money that moves out, and the export side

An import desk bills; it also pays. And most Karachi houses run export off the same office.

Other Charges Payables

A payable per mode, against a payable type: Shipping Line, Airline, Agent, Transporter, Custom Authority or Other. Finalising it debits Freight & Handling Cost and credits the Agent / Vendor Payable control.

Refund from Shipping Lines

Its own screen on both sea modes, with an Ocean Freight charges grid running rate to FC amount to PKR amount. It posts as a cost reversal against the payable, not as income.

Foreign agents, both ways

Invoices to agents, credit notes to agents, invoices and debit notes received from agents, credit notes received from agents — four screens per mode, and a credit note posts the exact reverse of the invoice it answers.

Loading Program
Sea export

The sea-export programme has its own screen and its own number series: Port, Wharf, T/Ship Point 1, Co Loader, CFS Yard, Weboc, Routing, Date Required, Cutt of Dt and the vehicle date.

Export paperwork
Sea export

Form E number and date in three sets, Instrument Type across Form E, Fin. Inst., EPZ NOC and GD, S/B No, S/B Place and S/B Date, M/R No, EGM No, S/I Filing Cut-Off, S/I Filed Date, CY/CFS Cut-Off, Pickup / Stuffing Date and the date and time the bill was handed to the line.

The bill of lading itself
Sea export

Place of Receipt, Port of Delivery with its code, Freight Payable At with its code, No. of Orig B/Ls, Country of Origin, Place of Issue, FOB/CIF, Loading Pier, B/L Released At and PCD.

Before you ask

What this does not do at the port

The things a Karachi buyer is right to check, answered before the demo rather than during it.

No terminal feed, and no line API

Terminal, Wharf, Shed, Stack and Berth are fields on the job. Nothing is read from a terminal operator's system and nothing is read from a carrier's. ETA, Arrived Date and the vehicle dates on the container rows are keyed by your staff or loaded from a CSV.

Nothing is filed to WeBOC or PSW

A chart-of-accounts record can hold a Weboc Id and a PSW Id, with both passwords encrypted at rest and never returned to a browser, and the Loading Program has a Weboc box. That is record-keeping. Your people still work the portals; no declaration leaves this system.

Detention is recorded, not calculated against a tariff

Free days, a rate per day and the resulting amount are fields. There is no per-line detention tariff table that works the charge out for you.

Voiding a document ignores the closed period

Posting into and un-finalising inside a closed period are both refused, and the refusal names your Data Block Date. Voiding a freight document is not held to the same boundary — the finance vouchers are, the document void is not. It is on the list to fix and worth knowing now.

See it on your own numbers

The fastest way to check any of the above is to open the sea-import screen yourself and look for the box you were expecting.
