Conference Ticketing for B2B Events: Invoices, VAT, Company and Group Bookings

A delegate buys an 890 euro conference ticket with her corporate card on a Friday afternoon. On Monday, her company’s accounts payable team writes to you. They need an invoice with the full legal name of the company, its VAT number and their purchase order reference, and they cannot book the cost without it. Two weeks later, her manager asks whether a colleague can go instead.

These company processes add requirements beyond a straightforward individual booking. In B2B conference ticketing, the attendee and the person handling payment are often different people, and your shop has to serve both. This guide covers the sales channels that work for business events, what an invoice must contain, how VAT on conference tickets works in the EU, how to handle company and group bookings, and what each payment method costs you.

What makes B2B conference ticketing different?

The Friday example has three parties in one ticket, and each of them wants something different from your shop:

• the attendee, who wants access, a programme and, at a matchmaking event, meetings with the right people;
• the booker, often an assistant or team lead, who may buy for several colleagues at once and add the names later;
• accounts payable, who never see your event but decide how quickly you get paid.

Most ticketing platforms for business to consumer (B2C) events are built for the first party only. The checkout, the price display and the confirmation email assume that buyer and attendee are the same person. For a business congress, that assumption breaks at the first company booking, when one person pays for five others.

That is why a B2B ticket shop is less about the checkout page and more about the data behind it: who the buyer is, whether that buyer is a business, which invoice they need, and who will actually walk through the door. Your real customer has a finance department.

How to sell tickets for a B2B event

Before any invoice can go out, the ticket has to sell. Business tickets rarely sell through one public page alone. They sell through the relationships around your event, and each relationship works best with its own ticket type or code:

• Members and partners: associations reach their members through newsletters and member areas. A member ticket type with its own price is clearer than a discount code that ends up on social media.
• Exhibitors and sponsors: they invite their customers and prospects. A quota of guest tickets or a personal code per exhibitor shows you which invitations actually convert.
• Speakers and staff: an invitation workflow with a free ticket type keeps them out of the paid funnel but on the attendee list, with a badge and a profile.
• Hosted buyers: qualified buyers apply, you approve them, and only then is their ticket confirmed. How such programmes are built is explained in our guide to what a hosted buyer programme is.
• The public ticket page: it reaches companies outside your network, through search, LinkedIn and partner websites. Treat it as one channel among several.

The structure matters for everything that follows. A ticket type per participant group lets you set prices, access rights and, at matchmaking events, meeting rights per group. How high those prices should be is a separate decision, and our guide to ticket pricing strategies for B2B events covers early bird levels, bundles and promo codes in detail.

The invoice: what accounts payable needs from you

Once the ticket is sold, the colleague in accounts payable takes over. Their checklist is short but strict, because in the EU the content of a VAT invoice is set by law. In Germany, for example, Section 14(4) of the VAT Act (UStG) sets out ten mandatory items, from the names and addresses of both parties and a unique invoice number to the net amount, the VAT rate and the VAT amount.

In practice, business buyers add a few fields of their own. This is what your checkout should collect:

The most common error is mixing attendee and billing data. A ticket made out to an attendee with her private address is of little use to her employer. Ask for the billing company in a separate step and let the booker reuse it for every colleague.

Electronic invoicing is the next change to plan for. In Germany, invoices between businesses established in Germany must now be structured e-invoices in a format based on the European standard. Paper and PDF invoices remain allowed for a transition period: for supplies made by the end of 2026, and by the end of 2027 for issuers whose turnover in the previous year was no more than 800,000 euros (UStG, Sections 14(2) and 27(38)). What counts is when the event takes place, not when the ticket is sold, and a PDF needs the recipient’s consent. Invoices up to 250 euros can always be sent on paper or as a PDF (Section 33 of the VAT Implementing Ordinance). Most congress tickets cost more than that. If you run an event in Germany and sell to German companies, ask your ticketing provider which e-invoice formats it can issue.

Timing matters too. Under Article 65 of the EU VAT Directive, VAT on a payment made before the service is supplied becomes chargeable on receipt of that payment. Tickets sold in March for a congress in September are taxed in March, not in September. Early bird revenue is also early VAT.

VAT on conference tickets: the event location decides

The invoice shows the VAT, but which country’s VAT is it? For tickets sold to businesses, EU law has a special rule, and it surprises many organisers. This section is general orientation, not tax advice. Your situation depends on where you are established and where your events take place, so confirm the treatment with a tax adviser.

Article 53 of the EU VAT Directive places admission to events “such as fairs and exhibitions”, when supplied to a taxable person, at “the place where those events actually take place”. The EU Implementing Regulation 282/2011 (Article 32) names “conferences and seminars” explicitly. A congress in Munich therefore charges German VAT to a Dutch company, a Swiss engineering firm and a German start-up alike.

Many organisers expect reverse charge for business customers from other EU countries. For in-person tickets, it does not apply: the place of supply is the event country, so the organiser charges that country’s VAT. Germany even excludes reverse charge where a foreign organiser sells admission to fairs, exhibitions and congresses in Germany (UStG, Section 13b(6) no. 4). A foreign organiser of a German congress therefore generally has to register for VAT in Germany and charge German VAT itself. Other EU countries apply their own versions of these rules, so check each country where you run events.

Online tickets follow a different logic. Since 1 January 2025, Article 53 “shall not apply to admission to the events referred to in the first paragraph where the attendance is virtual” (Council Directive (EU) 2022/542). For business buyers, the general rule then applies: the place of supply is where the customer is established, which for business customers in other EU countries usually means reverse charge. For private individuals who follow a streamed event, the place of supply is where they live.

For a hybrid congress, the consequence is practical: in-person and online access need separate ticket types, because they are taxed differently. One event, two VAT rules.

Both rules depend on knowing whether the buyer is a business. Under Article 18 of Implementing Regulation 282/2011, you may treat an EU customer as a business if they have communicated their VAT ID and you have obtained confirmation of its validity, together with the name and address. The EU’s VAT Information Exchange System (VIES) provides that check. Build it into your checkout rather than into a spreadsheet after the event. Outside the EU, for example in the UK or the US, different rules apply.

Company bookings, group tickets and name changes

Now back to the manager who wants to send a colleague instead. Company bookings raise questions that a consumer ticket shop never has to answer. Decide them before sales open, write them into your terms and show them at checkout:

• One booker, many attendees: decide whether every name is needed at purchase or whether the booker can add names later, and set a clear deadline for names.
• One invoice or several: some companies want one invoice for the whole team, others one per cost centre or per attendee. Asking at checkout is cheaper than reissuing invoices afterwards.
• Group prices: define the threshold, for example from five tickets, and whether it counts per order or per company across several orders.
• Name changes: a substitution rule, for instance free until a set date, keeps the attendee list accurate and limits resale.
• Cancellation and refunds: state what happens when a company cancels, by which date and at what cost. Business buyers read terms, and vague terms create disputes.

At a matchmaking event, the name deadline has a second job. Every attendee needs a complete profile before meeting requests open, otherwise the colleague who replaces the original booker starts the event without a single meeting. Set the name deadline before scheduling begins. A ticket without a name cannot book a meeting.

Payment methods and what they cost you

The last question is how the money arrives. Business buyers usually pay in one of two ways: by card at checkout, or by bank transfer after receiving an invoice. Card payment is immediate, but it has a price, and that price is higher for the cards many business buyers use.

Stripe classes commercial, corporate and business cards from Visa and Mastercard as premium cards. Across 300 tickets paid with corporate cards, the difference to standard cards adds up to more than 3,400 euros. These are the published rates of one provider, so compare them with the conditions of your own payment provider. Factor the fee into your ticket price or your payment options, not into a surprise at the end of the year.

Bank transfer avoids card fees but brings payment terms and reminders. Set a cut-off date after which only immediate payment is possible, so that no unpaid ticket reaches the badge desk.

From ticket to meeting: connecting shop, registration and check-in

Payment closes the purchase, but at a B2B conference it should open the next step. The weak point in many setups is the gap between the ticket shop and the registration: two systems, two logins, and attendees typing their details twice.

The handover between step four and step five is where data gets lost. If the registration fields are well chosen, the profile is ready for matchmaking in minutes, and our guide to registration questions for matchmaking shows which fields to ask for. What happens at the door is covered in our guide to event check-in and badge printing.

Converve’s own ticket shop is available and built around the same participant groups as the event platform. You set up ticket types per group, such as buyers, exhibitors, speakers or online attendees, with quotas, promo codes, early bird labels and invitation workflows, including hosted buyer approval before a ticket is confirmed. Every ticket contains the invitation to register on the event platform, so the purchase turns directly into a matchmaking profile. Payment runs via Stripe, Unzer, PayPal or credit card with support for EU reverse charge, and on site the QR badge handles check-in. How registration and check-in work today is shown on our registration platform page.

Frequently Asked Questions

What is conference ticketing?

Conference ticketing is the sale of admission to a conference, congress or trade event, including ticket types, prices, payment, invoices and check-in. In B2B, it also covers company bookings, VAT IDs and name changes, because the company that pays is often not the person who attends.

Do I charge VAT on conference tickets sold to companies from other EU countries?

For in-person tickets, generally yes. Under Article 53 of the EU VAT Directive, admission to an event supplied to a business is taxed where the event takes place, so a German congress charges German VAT to a Dutch company. This is general orientation; confirm your case with a tax adviser.

Does reverse charge apply to conference tickets?

For in-person admission, no: VAT is due in the country where the event takes place. Germany even excludes reverse charge for admission to fairs, exhibitions and congresses in Germany supplied by foreign organisers (UStG, Section 13b(6) no. 4). For online attendance by business customers in another EU country, reverse charge usually applies since 1 January 2025 (Council Directive (EU) 2022/542).

What must an invoice for a B2B conference ticket include?

The legal name and address of supplier and buyer, the supplier’s VAT ID or tax number, invoice date and number, the service with event date and place, net amount, VAT rate and VAT amount. Business buyers usually add their VAT ID, a purchase order number and the attendee names.

How do group bookings work for B2B conferences?

One booker buys several tickets for colleagues, often at a group price from a set number of tickets. Decide in advance whether names are needed at purchase or by a deadline, whether the company gets one invoice or several, and how name changes and cancellations work.

Can attendees transfer a conference ticket to a colleague?

That depends on your terms. Many B2B events allow a substitution within the same company until a set date. Define the rule before sales start, and make sure the new attendee completes their own registration profile, especially at events with matchmaking.

Conclusion: build the shop for the company that pays

A useful B2B ticket shop supports both your team and the company booking the tickets. Complete invoice details reduce queries, separate settings for in-person and online tickets help you apply the relevant tax treatment, and a clear deadline for attendee names gives participants time to arrange meetings.

Build the shop for the company that pays, and the purchase can lead smoothly into registration and programme planning.
