DemurrageNet: The platform that automates all Demurrage, Detention and Longstanding billing
Also used by shipping line commercial teams in direct contracts with key accounts.
Events, tariffs, alerts, invoicing and Profit centralized — so your team acts by exception, not in reactive mode.
DemurrageNet automatically calculates free time, applies tariffs by hierarchy (client > shipping line > route > region), generates Debit Notes in PDF, and shows Profit per file in real time. It replaces spreadsheet control with an operation that scales — you bill more clients with the same team, without losing Profit on contested charges or calculation errors.

What it costs to not control Demurrage, Detention and Longstanding
D&D costs identified too late
Without free time alerts, the team only notices the impact when the cost already has to be absorbed, contested or passed on to the client.
Manual calculation of tariffs by client, route and region
Each client has different negotiated conditions, each carrier has its tariff and each route has its rules. Without automation, the team gets the billing wrong — sometimes too low (lost Profit), sometimes too high (certain dispute).
Lack of predictability over D&D revenues and pass-throughs
Without an early view by client and route, billing, pass-throughs and margin depend on spreadsheets and parallel controls.
D&D reports and KPIs done manually
Indicators, history per container and performance by client require parallel spreadsheets and repetitive effort for each analysis.
Improper charges slip through for lack of an auditable history
Without events recorded per container, contesting charges, validating pass-throughs or sustaining disputes becomes a search through emails.
An entire team dedicated just to controlling D&D
Without automation, the only way to scale is to hire more people. Margin falls along with growth.
Every container monitored. Every charge justified.
Free time alerts — before, not after
DemurrageNet automatically calculates the free time from the pickup date of each container, considering the carrier tariff and the negotiated conditions. The system fires configurable alerts at D-7, D-3 and D-1 — your team acts before the deadline expires, not after the charge arrives.
Automatic Debit Note — PDF issued in one click
DemurrageNet calculates D&D and Longstanding per container in multiple currencies (USD, EUR — converted by PTAX or Siscomex) and generates the Debit Note automatically. Partial billing, grouping by client or route, discount and late-payment interest calculated automatically.
Customized tariffs with automatic linking to the file
Register carrier and client tariffs separately, with multiple periods (D+7, D+21, open-ended). When a file comes in, the system automatically links the correct tariff by hierarchy — a specific client takes priority over a general carrier, a specific port takes priority over a region. The calculation always reflects the real contract, by container type and by currency.
History of events and occurrences per container
Each event recorded — pickup, return, deadline extension, occurrence — stays linked to the container with date, responsible person and justification. When the carrier charges something improper, the history is the proof. Audits, disputes and root-cause analyses have a complete documentary basis, not memory.
Customized, scheduled reports with Profit calculation
Create report templates in XLS with any field available in the system — by client, carrier, route, period, status. Schedule automatic sending to groups of recipients (carriers, clients, operations team). DemurrageNet also calculates the Profit per file: the difference between the amount charged to the client and the amount paid to the carrier — margin visibility with no extra spreadsheet.
100% via browser — no installation, remote access
DemurrageNet runs entirely in the browser, with no local installation and no dependency on a VPN or internal server. Your team accesses it from anywhere — office or home office — with the same data and the same visibility.

Frequently asked questions about DemurrageNet
The questions that come up most often in meetings with freight forwarders, customs brokers and trading companies that bill Demurrage, Detention and Longstanding.
Why not just use spreadsheets?
Spreadsheets scale up to a point. Once you have dozens of clients with different negotiated tariffs, multiple shipping lines, multi-currency and monthly Debit Notes, human error becomes the rule, not the exception. Every contested charge is lost Profit.
DemurrageNet automates calculation, generates the Debit Note in PDF and keeps an auditable history of each container — you bill more clients with the same team, without losing margin to typing errors.
Our ERP already has a billing module — why another system?
Generic billing modules don't calculate D&D. They issue the invoice after someone has already calculated it in a spreadsheet. DemurrageNet is the specialist: applies tariffs automatically by hierarchy (client > shipping line > route > region), calculates multi-currency with PTAX/Siscomex, and generates the Debit Note in PDF.
Once generated, the Debit Note is exported to your financial ERP for accounting registration — via API, XML webservice, FTP/SFTP or XLSX. You gain automation where the ERP doesn't cover, without replacing what already works.
How does it work with multiple shipping lines and different tariffs?
Each shipping line has its tariff registered with multiple periods (D+7, D+21, open-ended) and by container type. When a file enters, DemurrageNet automatically applies the correct tariff.
Contract changes are entered once in the registry and reflect in all future files — no need to update spreadsheet by spreadsheet when a shipping line renegotiates.
How does it work with client-specific negotiated tariffs?
Client-specific tariffs override shipping-line tariffs. The hierarchy is configurable: specific client > specific shipping line > specific route > general rule.
Calculation always reflects the actual contract, not the list price. Key accounts with differentiated terms get correct calculation without depending on the analyst's memory.
Does it work with multiple currencies and daily exchange rates?
Yes. USD, EUR and other currencies converted by PTAX or Siscomex rates automatically. The Debit Note is issued with correct calculation on the day of issue.
You don't have to check the exchange rate manually or correct an invoice because the rate changed.
Is the Debit Note a tax document? How does it integrate with our financial ERP?
The DemurrageNet Debit Note is an internal billing document, with detailed calculation, and is not an electronic invoice (NFe).
DemurrageNet generates the PDF and exports the record to your financial ERP for the accounting entry. Integration via API (JWT Token), XML webservice, FTP/SFTP or XLSX spreadsheets — scoped to the scenario, without a months-long project.
What happens when a client contests a charge?
Each container event is recorded with date, responsible person and justification — pickup, return, deadline extension, incident.
When a charge is contested, the auditable history is the proof. Won contests become the rule; lost contests become rare. The Profit that was leaking through contests returns to the monthly result.
How do I measure the Profit I earned on each file?
DemurrageNet automatically calculates Profit per file: the difference between what was charged to the client and what was paid to the shipping line.
Reports by client, by route, by period show where the real margin is and where it's bleeding. You find out which contracts need renegotiation before closing the quarter — not after.
