Central billing for business travel across Karachi, Lahore and Islamabad

Central billing for business travel across Karachi, Lahore and Islamabad works best when one supplier holds the whole itinerary, one currency is fixed before the first quote, and every journey carries its own cost-centre code. That gives finance one document to approve instead of three city-by-city receipts in different formats. The questions that decide whether it actually works are narrower than most travel-card marketing suggests: which entity is billed, whether you pay before or after travel, how the rupee converts to sterling or dollars, and how tax is shown when the trip crosses Sindh, Punjab and the Islamabad Capital Territory, which each run their own sales tax on services. Settle those points in writing before the traveller lands at Jinnah International and the month-end reconciliation becomes a matching exercise rather than an investigation.

This guide is written for the person who signs the purchase order: a travel manager, finance controller or executive assistant in the UK, the Gulf or North America arranging a multi-city business trip to Pakistan for one visitor or a small team.

The short decision

• Two or more cities, same traveller, same week: use one account and ask for one invoice for multi-city travel, itemised per journey. Three local suppliers means three onboarding checks, three payment runs and three sets of terms for waiting time.
• One city, one airport run: a card payment at booking is usually simpler than setting up invoicing at all.
• Recurring visits by the same team: register a company account, agree a standing currency and tagging scheme, and invoice after each trip or monthly.
• Trips that include a flight between cities: bill the ground legs centrally, but keep the airline ticket on your normal air booking channel. Mixing them on one transport document confuses both approvals and tax treatment.

One account or city-by-city suppliers

A typical three-city itinerary for a visiting director looks something like this (an example, not a template): land at Karachi, two days of meetings, fly to Lahore, a day at a factory outside the city, drive up the M-2 to Islamabad, a ministry or bank meeting, then depart from Islamabad International. That is at least three airport movements, a long intercity drive and several in-city days.

Buying that locally means a Karachi operator, a Lahore operator and an Islamabad operator. Each may be perfectly good. The cost to you is administrative, and it compounds:

• Three vendor set-ups, each with its own bank details, tax registration and contract terms.
• Three definitions of “waiting time”, “day hire” and “cancellation”, none of them aligned.
• No single party responsible if the Lahore flight is delayed and the Karachi driver has already been released while the Lahore driver was never told.
• Invoices in different layouts, often in rupees only, arriving weeks apart.

One account moves that coordination to the supplier. The trade-off is concentration: you are relying on one network’s coverage in all three cities, so ask directly which of your legs they fulfil with their own vetted partners and whether any part is subcontracted further.

For the airport ends specifically, it helps to see how each city’s pickups are organised before you commit: Karachi airport transfers, Lahore airport pickups and Islamabad airport transfers each describe the meeting arrangements that your invoice lines will later refer to.

Currency choice and FX exposure

This is where most central billing arrangements quietly leak money. There are three separate currencies in play, and they are not always the same one:

1. The quote currency: what the price is expressed in when you approve it.
2. The charge currency: what your card or bank is actually debited in.
3. Your ledger currency: sterling, dirhams, riyals or dollars in your own books.

Every time two of those differ, someone converts, and someone takes a margin. Stripe’s own documentation spells out the mechanics for card payments: if the charge currency differs from the currency of the customer’s card, the card issuer may add a foreign exchange fee, and the issuer may also charge when the card and the merchant are in different countries, whatever the currency (Stripe supported currencies). That fee sits on your card statement, not on the supplier’s invoice, which is why it so often goes unexplained in expense claims.

Which currency to choose

• Pay in your ledger currency (GBP for a UK company, for example) if you want the invoice and the bank debit to match exactly. The supplier carries the conversion; you carry whatever margin is built into their rate.
• Pay in PKR if you have rupee funds or a Pakistani entity paying. You avoid a double conversion, but the home-currency cost moves with the rupee between quote and payment.
• Never mix within one trip. A Karachi leg in rupees and a Lahore leg in pounds on the same document is a reconciliation headache with no upside.

Pinning the rate

If the invoice converts, it should state which rate was used and on what date. The State Bank of Pakistan publishes daily reference rates for the rupee, including a mark-to-market revaluation rate and weighted average bid and offer rates against the US dollar. It is a sensible, neutral reference for your finance team to check against, even if the supplier or card network uses its own rate. Rates change daily, so quote dates matter: a price approved on Monday and paid on Friday is not the same number in sterling.

Cost-centre tagging per journey

A consolidated transport invoice is only useful if it can be taken apart again. The director in the example above may be visiting a sales office in Karachi, a supplier audit in Lahore and a regulator in Islamabad, which could be three budgets. If the invoice shows one total for “Pakistan trip, 5 days”, someone in finance will spend an afternoon emailing people to split it.

Build the tagging in at request stage, not after travel:

1. Agree the code format first. Cost centre, project code or PO number, whichever your ERP needs. Keep it short enough to fit a booking reference field.
2. Tag every leg, not every traveller. A single passenger can touch three cost centres in a week. A leg is the unit that has one purpose.
3. Tag waiting and extras to the leg they arose on. An extra hour at a Lahore factory belongs to the audit budget, not the general trip.
4. Name the approver per code. When a leg is added mid-trip (it will be), the supplier needs to know whose sign-off makes it billable.
5. Carry the code through to the invoice line. Ask to see a sample invoice before the trip and check the code appears on each line, not only in the header.

A company account is the practical container for this. When you create an iDrive company account, requests, confirmations and invoices sit under one login, which is what makes per-leg tagging repeatable rather than a one-off favour from whoever took the booking.

Deposits versus post-trip invoicing

The two models suit different buyers, and it is worth deciding which one you want before asking for quotes.

Most first-time corporate buyers start on prepayment and move to invoicing once there is a track record. That is normal and not a sign of distrust on either side. What matters is that the prepayment receipt and any later supplementary invoice share the same booking reference and cost codes, so they reconcile as one trip.

Whatever the model, remember what a request is. Sending a journey request, or seeing a price on screen, is not the same as an accepted booking with an assigned vehicle. Treat the trip as committed only when you have a written confirmation that names the legs, the vehicle class and the terms for waiting and cancellation. Those terms are the ones your invoice will be checked against.

Corporate travel card or invoice: the payment options compared

The question buyers usually ask first is whether to put it on the corporate travel card or ask for an invoice. The honest answer is that it depends on who is paying and from where.

Card payment through a hosted checkout

iDrive’s online checkout takes card payments through Stripe, so the card details are handled by the payment processor rather than typed into an email. For a UK or Gulf company paying with a corporate card, this is the fastest route and leaves a clean card-statement trail. Two things to know:

• Card-issuer foreign exchange and cross-border fees are set by your bank, not by the supplier, and appear only on your statement.
• A card payment gives you a receipt at the moment of payment. If your policy needs a formal tax invoice as well, ask for it at the same time, not three months later at audit.

Bank transfer against an invoice

Transfers suit larger programmes and companies whose policy bars card use above a threshold. International transfers can carry sending, receiving and intermediary bank charges, so the amount credited may be less than the amount sent. If you pay by transfer, agree who bears those charges before you send it, and quote the invoice number in the payment reference.

Paying from a Pakistani entity

If a local subsidiary or partner is paying in rupees, the invoice should be addressed to that entity, not the overseas parent. Your Pakistani finance team will also want to verify the supplier’s tax status; the Federal Board of Revenue publishes Active Taxpayer Lists for income tax and sales tax and runs an online verification portal for exactly this check.

Provincial tax differences between the three cities

This is the part of a multi-city business trip to Pakistan that catches overseas finance teams out, because it has no real equivalent in UK VAT. Since the Eighteenth Amendment, sales tax on services has been a provincial matter. Each of the three cities on this itinerary sits in a different tax jurisdiction:

Each authority has its own schedule of taxable services, its own rates and its own registration. Islamabad is a useful illustration of how granular it gets. The Islamabad Capital Territory (Tax on Services) Ordinance, 2001, in the version FBR publishes as amended to 30 June 2023, lists rent-a-car services at fifteen percent, and gives tour operators and travel agents a choice between fifteen percent and a reduced five percent without input tax adjustment. Passenger transport by car with a driver does not map neatly onto any single line, which is exactly why you should not assume how a supplier has classified it. Rates and schedules are revised in budgets, so treat any figure as a snapshot and check the current text.

What this means for one consolidated invoice

• Tax may differ line by line. A Karachi airport pickup, a Lahore day hire and an Islamabad transfer can fall under three regimes on the same document. Ask the supplier to show the tax treatment per line, or to explain why a single treatment applies.
• Intercity legs need a stated basis. A Lahore to Islamabad drive starts in Punjab and ends in the capital. Ask which jurisdiction the supplier treats that leg as falling under, and have them write it down.
• Registration numbers should match the tax charged. If an invoice charges a provincial tax, it should carry the corresponding registration. Punjab runs STRIVE, a real-time system for verifying sales tax invoices, which gives your Lahore-side team a way to check.
• Withholding is a separate question. Whether a Pakistani payer must withhold income tax from a supplier payment is for your Pakistani tax adviser, not the transport provider. Checking the supplier against the FBR Active Taxpayer List is a sensible first step.

None of this is a reason to avoid central billing. It is a reason to insist that the central invoice is itemised, because an itemised invoice is the only one on which a tax adviser can check each line.

What the invoice has to show

Before the trip, send your supplier this list and ask for a sample invoice laid out against it. If they cannot produce one, better to find out now.

• Legal name and address of the entity being billed, plus your PO number if you use one
• Supplier’s legal or trading name, address and any tax registration numbers
• One booking reference for the trip, with a sub-reference per leg
• For each leg: date, city, pickup and drop-off points, vehicle class, cost-centre code
• Base charge per leg, then waiting time, extra stops and tolls as separate lines
• Tax per line, with the jurisdiction or basis stated
• Currency of the invoice and, if converted, the rate and the rate date
• Any deposit already received, deducted clearly from the total

Tolls deserve a specific mention on the intercity leg. The M-2 between Lahore and Islamabad runs for about 375 km, with toll plazas at the interchanges and an M-Tag system in use since December 2021 (M-2 motorway). Toll amounts are revised from time to time, so ask whether tolls are included in the leg price or passed through at cost, and if passed through, on what evidence.

Setting up central billing for business travel, step by step

1. Write the itinerary as legs. Every airport arrival, every in-city day, every intercity drive, every departure. Mark which ones are fixed and which may move.
2. Decide the billing model. Prepayment or post-trip invoice, and the one currency the whole trip will use.
3. Assign cost-centre codes per leg and name the approver for any additions.
4. Send the whole trip as one request, not leg by leg, so the supplier can plan drivers across cities. The iDrive journey request form takes a full itinerary; for regular travel, use the company account so everything stays under one reference.
5. Review the written quote against your invoice checklist. Price per leg, waiting and cancellation terms, what happens if a domestic flight slips.
6. Confirm in writing. The trip is booked when the quote and terms are accepted and confirmed, not when the form is sent.
7. Log changes as they happen. A meeting that overruns in Lahore should be recorded against the Lahore leg that day, while people remember.
8. Reconcile within a week of return. Match each line to the approved leg, check the tax lines with your adviser, then pay.

Before you finalise the itinerary

At the time of writing, Karachi, Lahore and Islamabad, and the M-2 between Lahore and Islamabad, are not among the areas the UK Foreign, Commonwealth & Development Office advises against travelling to. The FCDO does advise against all but essential travel to Sindh north of and including Nawabshah, against all travel to Balochistan and much of Khyber Pakhtunkhwa, and it warns that protests and marches are planned in Islamabad, Rawalpindi and other cities. If a site visit, supplier audit or side trip would take a traveller beyond the three cities, check the FCDO Pakistan travel advice for that exact location first, and check your own company’s travel risk policy and insurance, which may be stricter.

If your travellers also need help with the day itself, rather than the billing, our sister service Pakistan Taxi has a practical guide to planning transport for several business meetings in one day. And if the same team also travels through the Gulf, our sister company Saudi Cab Co runs one transport account for organised travel in Saudi Arabia on the same principles.

Questions people ask

Can I get one invoice for journeys in Karachi, Lahore and Islamabad?

Yes, if one supplier handles all the legs. Ask for it itemised per journey, with a cost-centre code and tax treatment on each line, so it can be split and checked after travel.

Should we pay in pounds, dollars or rupees?

Pay in the currency your books are kept in if you want the invoice and the bank debit to match. Pay in rupees if a Pakistani entity is paying. Whichever you choose, use one currency for the whole trip and ask for the conversion rate and date to be stated.

Is the price on a quote request fixed?

No. A request or on-screen price is not an accepted booking. The trip is committed when a written quote with its terms has been accepted and confirmed.

Why might tax differ between cities on the same invoice?

Sales tax on services is administered separately in Sindh, Punjab and the Islamabad Capital Territory, each with its own schedule and rates. A multi-city invoice may therefore carry different treatments per line.
