Custom Rate Engine & Shipping Calculator Software
Accurate pricing is one of the most important parts of any logistics operation. When rates are stored in spreadsheets, scattered across departments, or updated manually, the result is inconsistent quoting, slow response times, and unnecessary errors.
We build custom rate engine and shipping calculator software that centralizes all your pricing logic into one reliable system, so every quote, API call, and invoice uses the same rules.
Pricing logic often lives in spreadsheets, disconnected tools, or brittle code that’s difficult to maintain and nearly impossible to scale. A dedicated rate engine consolidates every tariff model into one reliable foundation, supporting:
Instead of reinventing pricing for every new contract or region, the system adapts predictably and keeps logic consistent across all workflows.
Static rate sheets break the moment market conditions shift — demand spikes, lane imbalance grows, utilization drops, or customers push for new terms. A custom rate engine lets you update pricing without breaking contracts or resorting to manual overrides:
This keeps pricing competitive, protects margin, and eliminates the spreadsheet chaos that slows down decisions.
Pricing only works when every system uses the same logic. The rate engine exposes a fast, stable rating API so any workflow can retrieve accurate prices instantly:
Each response can include a detailed calculation breakdown, removing ambiguity and giving every team full transparency into how a rate was produced.
Manual quoting slows down sales cycles and creates mismatched expectations between what customers see and what operations approve. A shipping calculator embedded into your website or portal connects directly to your rate engine so:
This shortens decision time, improves customer experience, and cuts repetitive manual work for your teams.
Logistics pricing is naturally complex: tariffs, zones, mileage tables, service levels, weight breaks, fuel indices, accessorial fees, customer-specific logic, and contract exceptions.
A proper rate engine turns all of that into structured, machine-readable rules instead of scattered spreadsheets. The system calculates the correct price every time, regardless of who is quoting or where the request comes from.
With all pricing rules stored and versioned in one place, you stop reconciling conflicting quotes and maintaining multiple copies of the same tables. Every system uses the same logic, which improves accuracy and reduces operational overhead.
A rate engine works best when it connects seamlessly with the rest of your logistics ecosystem. The system can integrate with internal and external platforms through APIs, webhooks, scheduled syncs, or file-based exchanges - depending on what your workflows require.
Typical integrations include:
To calculate shipment costs during planning, tendering, carrier selection, or auditing.
To synchronize contract versions, accessorial updates, fuel indices, or service-level changes.
To automate billing, validate order data, or align shipment information with accounting and inventory.
To generate instant quotes, return pricing options, or support multi-carrier price comparison.
This integration model ensures pricing stays synchronized across the entire organization without manual updates or duplicated spreadsheets.
Custom pricing systems are not required for every organization, but they become essential when standard tools no longer support the operation. The need usually becomes clear in several scenarios:
When each carrier uses its own tariff structure, maintaining consistency manually becomes impractical.
Sales, dispatch, and customer support need instant, accurate results without depending on a pricing specialist.
Companies that adjust margins or run seasonal programs need logic that can adapt quickly.
A rating API becomes a core part of marketplace or self-service workflows.
Multi-currency, multi-market logic requires a system that supports variations cleanly.
When finance needs clear breakdowns, audit trails, and predictable calculations, a dedicated engine becomes the safest option.
These are the conditions where custom software outperforms generic calculators or SaaS tools.
Pricing in logistics is rarely linear. Real rates depend on contracts, tiers, zones, fuel, accessorials, and edge cases that don’t fit into simple formulas.
Our approach treats pricing as a core system, not a feature:
Rates are modelled as structured rules instead of hardcoded values
Contracts, customer-specific pricing, and carrier agreements are built into the foundation
Exceptions are part of the design, not afterthoughts patched on later
Architecture is built for change, so you can introduce new pricing models and carrier logic without rewriting everything
In real operations, that means fewer disputes, more predictable margins, and systems that can keep up as your network, contracts, and volumes evolve.

Yes. The engine is designed to handle multiple carriers, each with its own tariff structure, surcharge rules, or rating method. Lane-based, zone-based, mileage-based, or mixed approaches can all coexist without conflict.
Updates are applied in a structured format, which allows you to introduce new rates, adjust accessorial fees, or schedule future versions without disrupting ongoing pricing. All changes are tracked, and older versions remain available for auditing.
Yes. The engine includes the ability to simulate scenarios, evaluate lane changes, or preview the effects of margin adjustments. This helps teams make informed decisions without affecting production data.
The rating API is optimized for fast, consistent response times. It can handle both single requests and bulk rating operations. Caching and performance controls can be configured based on your traffic patterns.
Yes. The engine can power a customer-facing calculator, ensuring that the prices shown online match the rates used internally. This reduces misaligned quotes and improves customer confidence.
