How to Set Up Corporate Accounts With Monthly Invoicing

Corporate accounts are the single highest-margin, lowest-churn revenue stream available to a taxi, private hire or chauffeur operator. One mid-sized law firm or consultancy can be worth more in monthly recurring revenue than 200 cash street-hails — and once the account is wired into the client's expense workflow, it is genuinely difficult for them to switch.

This guide walks through the full setup: product design, onboarding, credit checks, dispatch configuration, automated monthly invoicing, VAT, payment collection and quarterly account reviews. It assumes you already run a modern corporate transport software platform; if you don't, the manual workarounds below will burn out your back office within a quarter.

Step 1 — Define Your Corporate Account Product

Before you sign a single client, write down what a corporate account actually is in your business. Most operators skip this and end up with bespoke deals that can't be repeated. Decide:

• Who qualifies. Minimum monthly spend (£500/£1,000/£2,500), minimum trips per month, or an industry filter (law, finance, consulting, healthcare, film & TV).
• Vehicle classes included. Sedan and executive only, or also MPV, SUV and chauffeur-driven 8-seaters.
• Credit terms. Net 14 for new accounts, Net 30 for established. Never Net 60.
• Rate model. List price, fixed % discount, custom rate card, or hybrid (fixed airports + % off metered).
• VAT handling. Standard 20% in the UK for sub-10-seater vehicles; show explicitly on the invoice.
• Booking channels. Web widget, branded portal, email-to-book inbox, phone, API.

Capture all of this in a one-page "Corporate Account Product Sheet" your sales team uses on every pitch. Consistency is what makes the product scalable; bespoke deals are what makes it un-scalable.

Step 2 — Build the Onboarding Pack

The onboarding pack is the single PDF or web form a prospective corporate client fills in before you turn the account on. A complete pack collects:

1. Legal company name, trading name, registered address, Companies House number, VAT number.
2. Primary billing contact, AP email inbox, PO requirement (yes/no), expected monthly volume.
3. Cost-centre list — departments, projects, client matter codes, event budgets.
4. Traveller roster — names and emails of employees authorised to ride.
5. Authorised bookers — typically EAs, office managers and travel coordinators with permission to book on behalf of travellers.
6. Booking preferences — preferred pickup buffer, vehicle class defaults, in-vehicle requirements (child seats, bottled water, signage).
7. Compliance requirements — driver vetting, NDA, GDPR DPA, insurance certificates.

A good corporate transport platform ships this as an in-product onboarding wizard the client fills in themselves, then submits for approval. The wizard saves your operations team roughly 90 minutes per account compared with email and spreadsheet onboarding.

Step 3 — Run a Credit and KYB Check

Extending unsecured credit without a check is the fastest way to write off five figures of revenue. For UK accounts, the standard sources are:

• Companies House — free, gives you filing history, accounts and director list.
• Creditsafe or Experian Business — paid (£25–£100/check), gives you a credit score, recommended credit limit and CCJ history.
• Trade references — two suppliers the prospect has had Net 30 terms with for 6+ months.

Set an opening credit limit at roughly two times the expected monthly spend. So a client forecasting £4,000/month gets an £8,000 limit. If the credit check fails or the company is newly incorporated (under 12 months), don't refuse the account — offer a card-on-file fallback where every trip is pre-authorised to a corporate card and consolidated at month-end. That keeps the consolidated-invoice user experience while removing your credit risk.

Step 4 — Configure the Account in Your Dispatch Software

This is the step that determines whether monthly invoicing runs on autopilot or eats two days of admin every month. Inside your dispatch console, create:

• A company record with a unique alphanumeric account code (e.g. ACME-001).
• A billing profile — billing email, currency, VAT number, payment terms, preferred invoice format (PDF + CSV trip log).
• A cost-centre list imported as a CSV so bookers select from a dropdown rather than typing free-text (free-text destroys reporting).
• A negotiated rate card — the agreed pricing logic that overrides public rates whenever this account books.
• A credit limit with automatic warning at 70% utilisation and a hard stop at 100%.
• An authorised booker list — each booker gets their own login with role-based permissions.
• A traveller roster — bookers can only book for travellers on the approved list.

The rate card, cost-centre dropdown and credit limit are the three controls that make corporate billing self-policing. A spreadsheet operation cannot enforce any of them.

Step 5 — Set Up Booking Channels for the Client

Corporate clients book differently to consumers. Make sure every channel they will use is enabled:

• Branded web booking portal — the client logs in, sees only their company's rates, cost centres and travellers.
• Email-to-book inbox — an EA forwards a meeting invite, your system parses pickup, drop-off and time, replies with a confirmation.
• Booking widget with account code — embedded in the client's intranet so any employee can book without a login.
• Phone bookings — your dispatchers tag every call with the account code; the trip flows into the same invoice.
• API or SSO for enterprise clients integrating into Concur, Egencia or an internal travel tool.

Run a 30-minute training session with the client's primary bookers in the first week. Account adoption is highest when the EAs feel ownership of the tool, not when it's a black box managed by your operations team.

Step 6 — Automate the Monthly Invoice Run

The invoice run is where amateur operators bleed margin and professional operators sleep. A clean run does the following automatically on the 1st of every month:

1. Closes the previous month's trip ledger at 23:59 on the last day.
2. Pulls every trip for the account, applies the negotiated rate card, adds extras (waiting time, tolls, parking, child seats).
3. Applies VAT at the correct rate based on vehicle class and journey.
4. Groups trips by cost centre with subtotals.
5. Generates a single consolidated PDF invoice with a unique sequential invoice number.
6. Generates a matching CSV trip log (date, time, traveller, pickup, drop-off, cost centre, net, VAT, gross).
7. Emails both files to the client's AP inbox with a payment link.
8. Logs the invoice in your accounts receivable ledger and in your accounting platform (Xero, QuickBooks, Sage) via API.

The CSV trip log is non-negotiable. Every corporate AP team needs it to reconcile to internal expense reports. Operators who skip it lose accounts to competitors who don't.

Step 7 — Deliver the Invoice and Collect Payment

The cleanest collections stack for a small or mid-sized operator looks like this:

• Default: GoCardless Direct Debit on day 14 or day 30. Cost ~1%, almost zero late payments, no chasing.
• Fallback: Stripe-hosted payment link in the invoice email for clients who refuse Direct Debit.
• Manual: BACS bank transfer for finance teams that insist on it.

Automate reminders at day +3, +7 and +14 past due. After day 14 your account manager calls personally — not your dispatcher, not an email. After day 30, freeze the account from new bookings until the balance clears. A clear, polite, mechanical chase ladder protects the relationship and your cash.

Step 8 — Review the Account Quarterly

The single highest-leverage thing a corporate account manager does is the quarterly business review (QBR). Bring a one-page deck covering:

• Trip volume vs. last quarter, year-on-year.
• On-time pickup % and complaint count.
• Top five cost centres and top five travellers.
• Estimated savings vs. equivalent rideshare or expense-claim spend.
• Vehicle-class mix and any service expansion opportunities (airport transfers, roadshow days, event nights).
• One renegotiation ask — either an expansion to a new office or a small rate adjustment.

Use your reporting and analytics dashboard to produce this in 20 minutes, not a day. QBRs are also where accounts get expanded — from "our London team" to "our London, Edinburgh and Dublin teams" — which is the single biggest growth lever in a corporate book.

Common Mistakes That Kill Corporate Accounts

• Free-text cost centres. Bookers spell "Mergers & Acquisitions" three different ways and the client's AP team can't reconcile.
• Manual rate overrides. A dispatcher applies the wrong discount; the invoice goes out wrong; the client loses trust.
• Late invoicing. The 1st of the month is sacred. Invoices going out on the 7th push payment by a full extra cycle.
• No CSV trip log. A PDF alone cannot be reconciled by anyone running a real AP system.
• No credit limit. You discover the £14,000 problem when the cheque doesn't arrive.
• Booking from anywhere. Travellers book on personal cards "just this once" and the trip never makes it onto the account invoice.
• No QBR. The account quietly drifts to a competitor over 18 months because nobody owned the relationship.

What Good Corporate Transport Software Looks Like in 2026

If you're evaluating a platform specifically for corporate billing, the non-negotiable feature list is:

• Multi-company account hierarchy with cost-centre support.
• Per-account negotiated rate cards including airport fixed fares and tiered waiting-time rules.
• Authorised-booker roles and traveller rosters with permission controls.
• Automated month-end invoice and CSV generation, scheduled and emailed.
• Native Xero / QuickBooks / Sage integration for the ledger sync.
• Direct Debit (GoCardless or equivalent), Stripe payment links and BACS reference matching.
• Credit limit monitoring with utilisation alerts.
• Email-to-book parser for EA bookings.
• API and SSO for enterprise tenants.
• A reporting suite that produces a QBR-ready PDF in one click.

The Taxi Web Design corporate transport platform ships every one of these as standard. If you'd like to see the invoice run, cost-centre logic and Direct Debit reconciliation end-to-end on a live dispatch dashboard, book a 30-minute demo with our team.
