Contract Hire and Leasing Software: Rental Billing Features to Look For

This guide follows a contract from set up to final invoice, showing what contract hire and leasing software should handle at each stage. For the wider picture, see our guide to choosing vehicle rental software.

What Does Contract Hire and Leasing Software Do?

The software connects the agreement, its vehicles and the invoices they produce. Operations and billing share one record, so when a vehicle goes on hire, is swapped or comes back, billing knows straight away.

Fleet management software keeps vehicles legal and ready for work; contract hire and leasing software makes sure they earn what was agreed. For the vehicle side, see what fleet management software does.

Contract hire vs flexi hire: how the billing differs

Contract hire is long term, with stronger underwriting terms, tailored service levels and fixed mileage allowances. Billing is predictable, but every term must be honoured for the life of the contract.

Flexi hire is short term, usually from stock. Terms are simpler, but vehicles change more often. Most operators run both, so their vehicle rental system must handle both on one platform.

Where do agreements and billing usually drift apart?

Without a system that applies agreed terms automatically, teams rely on documents and spreadsheets, and familiar problems follow:

• invoices raised late or missed altogether
• credit limits and credits calculated by hand and hard to trust
• excess mileage not charged, or charged on wrong readings
• fuel, delivery, collection and PCN charges not passed on
• customer PO or consolidation requirements not met
• damage recharges raised late, against BVRLA guidance

The result is missed revenue and more queries. Replacing spreadsheets with contract hire and leasing software starts with how each contract is set up.

Setting Up Hire Agreement Software Around Your Contracts

Good billing is decided before the first invoice, so the rental billing features that matter most start with set up. Hire agreement software should offer templates for common terms, plus specific agreements for individual customers. Set up typically covers:

• Underwriting terms: advance rent, deposits and credit limits for each customer, with available credit recalculated as contracts are confirmed or cancelled.
• Billing frequency: weekly, every X weeks or monthly, aligned to calendar months, mid month or end of month.
• Billing calendar: seven day or working week, so daily rates follow what the customer agreed.
• Billing type: advance or arrears, set per contract.
• Price lists, tax and charges: customer price lists, VAT rules and default charges such as admin, delivery and collection fees, added by booking type and vehicle category.
• Customer rules: whether a PO number is mandatory, and how invoices are consolidated (by PO, contract ID or booking type).

Applying rates, mileage allowances and SLAs to every vehicle

Whether a contract covers one vehicle or hundreds, rates, mileage allowances and SLA pricing should carry onto every vehicle on the booking. A rate agreed monthly but billed weekly should be converted consistently.

Once the vehicle goes on hire, billing begins.

How Does Contract Hire Billing Software Run the Billing Cycle?

A typical contract runs from underwriting billing through first and recurring invoices to the final invoice, end of hire charges and deposit settlement. Contract hire billing software should manage each step without manual tracking, and each stage relies on different rental billing features.

Advance rent, deposits and proforma invoices

Advance rent and deposits are invoiced first, often as proforma invoices so the customer pays before the vehicle goes out. Advance rent is then settled against the charges it covers, with the remaining balance always visible. A contract should not close while any balance is outstanding.

Advance vs arrears billing for contract hire

Contract hire is usually billed in advance; arrears billing suits some short term or variable hires. Either way, each vehicle should carry its next invoice date, with drafts raised overnight for review or posting. If billing details change mid hire, future invoices should follow automatically.

Consolidated invoices and purchase order numbers

Large customers rarely want one invoice per vehicle. Good rental billing features let you group charges by contract, PO number or other customer criteria, and regroup them manually when needed. Where a PO is mandatory, the invoice should not post without it, and contract PO numbers should carry to every line. Consolidated monthly invoices with purchase order numbers remove a common cause of queries.

Tracking mileage and predicting excess charges

Excess mileage is a common source of billing errors, as one wrong reading can produce a charge that is wildly off. Readings should be validated as they arrive, with anomalies held for review. The system then compares mileage to date with the allowance to date to show the current excess, and projects usage to the end of the hire to predict the final charge. That early view lets you agree a mileage adjustment or extension with the customer before the bill arrives, and gives finance a clearer picture of revenue to come. That is how to calculate excess mileage charges on contract hire with confidence.

For example: a vehicle on a 12 month hire with a 30,000 mile annual allowance has covered 12,000 miles after 120 days. At about 100 miles a day, it is on course for 36,500 miles by the end of the hire: 6,500 miles over the allowance, or £520 at an agreed 8p per mile.

Of course, contracts rarely run exactly as planned.

How Does Contract Hire Software Handle Changes During the Hire?

Mid-contract changes are where rental billing is tested hardest. Treat each one as an exception with its own controlled process, so regular billing keeps flowing.

Re-hires, de-hires and extensions

Vehicles are returned early (de-hire), put back on hire (re-hire) or kept longer. A de-hire should respect the minimum hire period and update the billing end date automatically. When handling contract extensions mid hire, the booking should carry the same rates, allowances and billing rules, with no gap in billing.

Replacement vehicles: free of charge or chargeable

A broken down or off road vehicle may be replaced. Some replacements are free under the SLA, others chargeable, and rental billing features should tell the difference automatically.

Midlife charges: PCNs, damage and interim mileage

Not every charge is planned. During a hire, penalty charge notices arrive, vehicles return with fresh damage, mileage runs ahead of the allowance, or a vehicle misses a scheduled event such as an MOT because it was not made available. A PCN should be added to the right booking with its admin fee, in bulk if needed and even after the hire closes. Damage, interim excess mileage and missed event charges should be raised as they arise, not left for the final invoice.

Non chargeable days, one off charges and credits with approval

Credits arise for many reasons. A vehicle billed in advance that comes back early should be credited for the unused period automatically. Non chargeable (grace) days, when a vehicle goes off road (VOR) through a recall or breakdown, are recorded with a reason and removed at the daily rate. Disputes and goodwill gestures need credits too.

Each credit should be calculated by the system, reviewed under company policy and posted only once approved, with earlier credits visible to the reviewer.

And eventually, the hire ends.

Ending the Hire: Final Invoice and Deposit Settlement

The final rental invoice closes out the hire charges. Fuel, AdBlue and excess mileage charges are created automatically at check in by comparing readings with check out and pricing any difference at agreed rates. Damage recharges should be raised promptly, itemised and backed by check out and check in photos. Finally, the deposit is settled and released, with a clear record of any offsets.

That completes the contract’s journey. Each invoice has a journey of its own.

Automating Contract Hire Invoicing With the Right Checks

Of all rental billing features, automation saves the most time. Most billing should run without anyone touching it. The goal is a highly automated cycle where people only deal with exceptions.

Simulating billing before it runs

As every invoice starts as a draft, billing can be simulated first, showing expected billing for any period, highlighting issues before posting and letting you share figures early where customers require it.

What runs automatically and what needs review?

Every invoice moves from draft to review, posting and issue, and you decide how much is automatic. Routine invoices post once every condition is met, such as a valid PO number, account codes on every line and an open period. Others wait for a person: often the first and last invoice of each hire, and always credit notes and zero value invoices. If one line fails, the whole invoice waits. That is how to automate contract hire invoicing without losing control, and what contract hire and leasing software with automatic billing in the UK should offer.

Checking invoices before they go out

Every invoice should carry enough detail for the customer to understand it. With the right rental billing features, every run is checked first, so missing data, zero values and unusual readings are flagged rather than posted through. For bulk corrections, such as adding PO numbers, spreadsheet export and import saves hours.

Audit trail and security

Every invoice should link back to its calculation, booking and contract, with every manual change and billing run logged. Clear rules on who can view, edit and post billing data support segregation of duties.

Posting into the right financial period

A fiscal calendar marks each month Open, On Hold or Closed, and invoices post only into open periods. Kept in step with the finance system, closing a period in one closes it in the other, so month end closes cleanly.

Sending Invoices and Handling Queries

Who receives each invoice?

Emails configured by contact type send each invoice to the right people. Posted invoices go out automatically, together or one per email, and can be resent on request.

Resolving invoice queries quickly

Clear invoices reduce queries, but the system should still resolve them quickly. Each query is routed to the right person with a set resolution time, then closed with a credit or the information needed. A customer portal lets customers download invoices and supporting documents, raise and track queries, monitor mileage and see their own analytics, so nothing gets lost in an inbox.

With billing running cleanly, finance can see the full picture.

Revenue Visibility for Finance Teams

For a finance director, billing is about revenue. Good rental billing software posts each charge to the correct category automatically, keeping rental revenue separate from fuel, mileage and recharges. Contract hire and leasing software should connect with your accounting system, whether SAP, Dynamics 365, Sage or Xero, so invoices flow across without rekeying. As the monthly rental is set in the contract, expected and actual billing can be compared; a vehicle off the road without a replacement shows as a shortfall.

Sales set up the contract, billing manages exceptions, daily billing runs automatically, and dashboards show finance revenue by month, customer, contract and charge type.

How to Evaluate Fleet Leasing Software in the UK?

Whether you call it contract hire and leasing software, fleet leasing software, contract hire software, vehicle hire software or a vehicle rental management system, judge it on your billing.

Rental billing features to check with each provider

• Can advance rent and deposits be invoiced, settled and tracked automatically?
• Does it support weekly, X weekly and monthly billing, in advance and in arrears?
• Can invoices be consolidated by contract or PO, with PO numbers enforced?
• Are fuel and excess mileage charges created automatically at check in?
• Are credits calculated by the system and approved before posting?
• Can you control what posts automatically, and block posting into closed periods?
• Does posted revenue flow to your finance system in the right categories?

Contract management software vs contract hire software

General contract management software stores agreements and tracks renewals. Contract hire software applies each agreement’s terms to every vehicle and turns them into invoices. For rental billing, you need the second.

Testing a real contract through each shortlisted system

Ask each provider to run one of your contracts end to end: advance rent, months of billing, an extension, a replacement, a credit and the final invoice. Seeing how its rental billing features cope with your real work beats any demo.
