About

Why we built Partner4Events

Sponsors and vendors make events possible, but managing them usually means spreadsheets, long email threads and requesting the same logo three times. We built Partner4Events so organizers can run every partnership from one place, and so their partners have a clear, simple portal instead of a pile of emails.

Features

Less chasing, more time for your event

From the first invitation to the thank-you recap, in one portal.

Keep every dollar your sponsors pay

Get paid by check, wire, PayPal, Venmo or your own link. We never take a cut.

Instead of: a fee on every sponsorship

Stop chasing logos and paperwork

Ask once. Partners upload everything in their portal, with automatic reminders.

Instead of: follow-up emails

Move beyond spreadsheets

Each partner gets one portal for files, agreements, invoices and messages.

Instead of: spreadsheets and email threads

Every deadline at a glance

What’s done, late or missing, on a calendar or a timeline.

Instead of: a status column you update by hand

Agreements signed in the portal

They sign with an email code, you countersign if needed, and both get the signed PDF.

Instead of: print, scan, chase

Bring your spreadsheet

Import from Excel, CSV or Google Sheets. Free, and nobody is emailed until you invite them.

Instead of: retyping last year’s list

One message, or one for everyone

Chat with one partner, or send an announcement to the ones you pick.

Instead of: reply-all chains

Package builder and proposals

Build your sponsor and vendor packages once, then send a proposal link. Accepted ones become partners in one click.

Instead of: re-entering deal details

Your favorite AI, now your event assistant

Connect Claude or ChatGPT to your portal (MCP) and ask who’s late, what’s missing or what’s unpaid. Read-only for now, and it sees only what you see.

Instead of: digging through screens for answers

Answers to the questions organizers ask most

Getting started

How do I set up my first event?

Create a free account, open Events and give your event a name. During our launch offer, your first event is free at any size: pick the size you need, up to 200 sponsors and vendors, with no card. Other events start free with 2 sponsors or vendors and every feature.

Does importing my partner list use up my slots?

No. Import your whole sponsor and vendor list for free, from an Excel file, a CSV or a Google Sheets link. Imported partners wait as drafts and don’t count toward your event’s slots. A slot is used only when you send a partner an invitation, and it’s given back if you withdraw the invitation or it isn’t accepted within 14 days.

How do I invite a sponsor or vendor?

Open Partners and use “Invite by email”. Choose the event, whether it’s a sponsor or a vendor, and their package. Then pick what they need to deliver, review the invitation and send it. They receive a secure link to their own portal.

What do my sponsors and vendors see?

Their own portal: what you need from them and by when, documents to sign, invoices, shared files and messages. Nothing about other partners.

Can my team work in the same account?

Yes. Invite teammates from Team & permissions and give each one a role. Permissions control who can manage events, sponsors, team members and financials. Team members are included with every plan: you plus 1 teammate on the free plan, 3 to 20 depending on the pass size, and unlimited on Pro. Need more on a pass? Ask us and we’ll add extra seats.

Moving your existing partners in

What can I import?

An Excel file (.xlsx), a CSV, TSV or JSON file, or a Google Sheets link shared as “Anyone with the link”. If your list lives in another app, save or download it as a spreadsheet first.

Do my column names have to match yours?

No. Columns like “Sponsor Name”, “Contact Person”, “Email Address” or “Sponsorship Amount” are matched automatically, and first and last name columns are combined. You can change any match, uncheck columns you want left out, and keep extra columns (like notes) with each partner.

Will importing email my partners?

No. Every imported row becomes a draft. Nothing is sent until you open a draft, choose its requirements and send the invitation.

What happens to duplicates and bad rows?

Before anything is saved, you see how many rows are ready and which will be skipped, with the spreadsheet row number and the reason: a missing or invalid email, a partner already in that event, or the same email twice in the sheet.

Can one spreadsheet cover several events?

Yes. Add an Event column and each row goes to the event with that name. Rows with a blank or unrecognized event go to the event you choose.

Can I get my data out again?

Any time. Export your sponsors and vendors to Excel or CSV from Partners, or export a whole event, including deliverables, invoices, attendees and team, from the Event tab.

Pricing and refunds

Is there a free plan?

Yes. During our launch offer, your first event is free at any size, up to 200 sponsors and vendors, with every feature included. Your other events are free with 2 sponsors or vendors, enough to try the whole workflow. No card needed, and your launch event keeps its size after the offer ends.

How does the launch offer work?

Sign up, create your first event and choose any size, from the Starter pass (up to 10 sponsors and vendors) to the Large pass (up to 200). It’s free, with no card and nothing to cancel. One free sized event per account, for a limited time. When paid sizes open, they come with 30 days free before the first charge.

Should I buy passes or Pro?

Start with the launch offer: your first event is free at any size. Paid passes (from $99 per event) and Pro ($99 a month billed yearly, for 10 active events) open soon. If you run several events a year, Pro usually works out cheaper; message us and we’ll let you know when it’s ready.

What counts as a partner slot?

A sponsor or vendor uses a slot when you send them an invitation, and keeps it once they accept. Drafts and imported lists are free, and so are contacts: add as many people from each company as you like. If you withdraw an invitation, or it isn’t accepted within 14 days, the slot is released automatically.

What if my event grows?

During the launch offer your first event can be any size, so pick one with room to grow. Need more later? Message us.

What is the refund policy?

During the launch offer there’s nothing to refund: your first event is free and no card is taken. When paid sizes open, cancel within the first 30 days and nothing is charged; after the charge, a pass on an event is final.

What if my event is canceled?

Open the event’s details and choose “Cancel event” any time before the start date. The event becomes read-only and each sponsor and vendor is emailed that it’s canceled, with any note you add. A free launch-offer event has nothing to refund. Refunds to your sponsors and vendors are between you and them, through whichever way they paid you.

Do you charge fees on sponsor payments?

No. We never add a platform fee to your sponsors’ or vendors’ payments. If a sponsor pays you by card or bank transfer, their payment provider charges its usual processing fee; we add nothing on top.

Can I change the event date?

Every event needs a start and end date. You can change the dates up to twice. Once an event has a size, the new start date can be at most 30 days after the original. Changing the name, start and end times, venue or details is always free. Events become read-only 60 days after they end, and you can still view and export everything.

Payments, contracts and files

How do sponsors pay me?

Add the ways you accept payment — PayPal, Venmo, Cash App, Zelle, check or bank transfer — under your account menu → Getting paid. Sponsors and vendors see those options on each invoice, tell you what they sent (for a check, the check number and bank), and you confirm it arrived before it’s recorded. Bank details are only shown to a partner who chooses bank transfer. Money goes straight to you; we add no fee. Online card payments open soon.

Can partners sign agreements in the portal?

Yes. Attach the agreement as a PDF to an e-signature request. The sponsor or vendor confirms it is them with a one-time code sent to their email, signs, and you countersign. Both sides download the same signed PDF, with a certificate of completion recording who signed, when and from where.

Can I share files with partners?

Yes. Upload files to Documents, organize them in folders, and share each one with the sponsors, vendors or teammates who need it.

Can I use Claude or ChatGPT with my events?

Yes. Connect Partner4Events to your AI assistant from Security → AI assistants in the portal, then ask things like “Which sponsors still owe their logo?” or “What’s still unpaid for the gala?”. It’s read-only: the assistant can’t change, send or delete anything, and it only sees what your role allows. Disconnect it there any time.
