Every Counter Ancillary, Unified in One App
Capture fuel settlements, insurance waivers, child seats, cross-border authorisations and winter-tyre compliance from a single rental agreement — with automatic compliance rules, pre-issue safety warnings and a cross-ancillary agent scorecard built in.
The problem
Rental counters lose margin and court liability on the extras that sit beside every rental: fuel disputes, missed insurance upsells, child seats fitted against a live airbag, border crossings without proof of entitlement, and foreign fines for a missing winter tyre. Generic rental and fleet apps record these as free text, and the single-ancillary apps on the market force an operator to buy, install and reconcile five separate tools with no shared reporting across them.
The solution
Car Rental Extras & Ancillary Charges puts every counter ancillary on one rental agreement, in one Odoo 20 app. Automatic charge calculations, location- and date-aware compliance rules, pre-issue safety warnings, photo evidence and a cross-ancillary agent scorecard turn five disconnected workflows into one auditable, revenue-protecting counter process.
Everything the counter needs, in one app
Every capability below is implemented in the module.
Unified Rental Agreement Hub
Every ancillary links to one rental agreement with two-way smart buttons and cascade cleanup, so agents and auditors move instantly between the rental and each extra — no orphaned records across five separate apps.
Transparent Fuel Settlement
A pictorial fuel-gauge selector (Empty/Quarter/Half/Full) replaces ambiguous text, and litres-short and refuelling charge are calculated per policy — full-to-full, full-to-empty, prepaid tank or same-to-same — across petrol, diesel, hybrid, EV, CNG and LPG, with the full charge formula shown to the customer.
Insurance & Excess Waiver Tracking
Record every waiver product offered and accepted, its excess level and premium, and log claims against it — so attach and take-up rate, the highest-margin counter metric, becomes measurable instead of anecdotal.
Child Seat Issue & Fitting With Safety Warnings
Capture ECE R44/R129 standard, group, ISOFIX position and shell expiry, with an automatic red warning — and a hard block on confirmation — for an expired shell or a rearward-facing seat paired with a live front airbag.
Cross-Border Travel Authorisation
Track authorised and prohibited countries, hire certificate and green card details, and auto-fill the mandatory equipment matrix — vignettes, hi-vis vests, triangles, breathalysers — required for each destination.
Winter Tyre & Seasonal Compliance
Record tyre marking, tread depth and snow chains, and auto-match the seasonal rule for the rental's destination and dates — flagging a non-compliant fitment before the vehicle leaves the counter.
Location- & Date-Aware Compliance Rule Engine
Cross-border equipment and winter-tyre rules are matched automatically from the rental's destination countries and pickup/return dates, removing the manual country-list lookups that cause the omission errors competing apps leave unsolved.
Cross-Ancillary Agent Scorecard
A single pivot rolls up revenue, waiver attach rate, average litres short and claims by counter agent across all five ancillaries — the one performance view no single-ancillary competitor offers.
Photo Evidence & Driver-Facing Confirmation
Attach handover and return photos to every ancillary record, and print a per-rental confirmation document summarising fuel policy, compliance duties and fittings for the customer to acknowledge.
How it works
Open the rental agreement
Create or select the rental agreement for the customer, vehicle and destination countries.
Record each ancillary at the counter
Capture fuel level, waiver acceptance, child seat fitting, cross-border authorisation or winter-tyre compliance from the agreement's tabs.
Review automatic alerts and charges
Compliance rules, safety warnings and charge calculations populate automatically, with evidence photos attached at handover and return.
Confirm and print the customer record
Confirm each ancillary, then print the driver-facing confirmation document for the customer to acknowledge before departure.
