Rosie & Nathaniel: send the proposal

Monday to Friday, at your desk

The enquiry arrives with the date already checked.

Rosie and Nathaniel, Elmore Court, 140 guests. Before you open it, it has been checked against your diary: that Saturday is free.

Then a proposal and a contract, signed online, and invoices that chase themselves, paid by card through Stripe, bank transfer or PayPal.

Enquiries, proposals, contracts and invoices are on the Complete plan.

The look of the wedding

Describe the wedding once. Every mood board is drawn to match.

Write a few lines about how the day should feel and tick the parts you want: the flowers, the tables, the ceremony, the cake. Each board comes back as photographs in the wedding’s own colours, with a few lines under every picture your florist and stylist can work from.

Add the venue’s website and the pictures are drawn in its own rooms. When you are happy with it, the couple open it as a lookbook.

The guests

Every reply lands on the list. Every allergy reaches the kitchen.

Replies file themselves, with meals and dietaries. Draw the table plan, then give the caterer a dietary sheet by table, allergies first.

A couple's table plan drawn as a floor plan on a laptop: the top table, a long serpentine of 40 with a round table in each of its bends, and more tables, with every seat numbered, the guests' initials in the taken seats, allergies and diets marked in amber, and the dance floor.
The top table on the table plan: eight guests with their meals, and one pescatarian and one gluten free guest noted underneath for the caterer.

Invitations, 200 designs

An envelope with their name on it. Their reply on your list.

Every design is already set in the couple’s own words. Change any line, the foil, the liner and the wax seal, then send it from the guest list. Each household opens its own envelope, and their reply comes straight back to you.

On your guest list, meals and all

Replies, meals and dietary needs land on the guest list as they come in. The couple can design it with you, and only you send it.

A planner's inbox on a laptop: her folders with one for each wedding, Bethany and Will's folder open with its emails listed, and the newest one in the reading pane.

Client email

Every client email, already on its wedding.

Connect your Gmail, Outlook, Microsoft 365 or other mailbox and client email comes in already sorted: each couple’s in their wedding’s own folder, suppliers and enquiries in theirs. Anything it cannot place waits for you to file.

Reply from your own address, with five seconds to change your mind, then flag, snooze and label as you would anywhere else. Your mail stays private to you: nobody else on your team can read it.

Impress your couples

Their own portal, showing only what you choose.

Each couple sees the parts you turn on: the day coming together, the countdown, and their budget, £19,660 paid and £5,576 remaining. Any budget line can be hidden. A beautiful place for them to watch their wedding come together, with your name on it.

Their wedding website

A wedding website for every couple.

Twelve designs, each in six colour schemes. It fills itself in from what you already hold: the day, getting there and the reply form, and every reply lands on your guest list.

The couple write the words and add their photographs. The design, the address and who can see it stay with you.

Katrina Seear Co-founder, wedding planner

Katrina has spent her whole working life in hospitality. She ran the team at Elmore Court, sales and hospitality, and still plans and coordinates weddings herself. She knows how a day should run, and how to make it the best day of a couple’s life. Every screen has been through her.

Gary Nunn Co-founder, wedding photographer and filmmaker

Gary had his first camera at three and was building his own computers as a teenager. He became an IT manager for one of the world’s largest companies, then turned to weddings, and has photographed a thousand of them all over the world since 2002. Every photograph on this page is his.

Together for eight years, we’re a couple with more than thirty-four years of weddings between us. We live and breathe the wedding industry, and we both still work in it, Gary behind the camera and Katrina planning and building full-scale weddings, from big marquees to venues across the UK. We built I Said Yes the way we work. It takes care of the details so you can take care of the people.

Four questions planners ask.

A ring box and heart-shaped sunglasses on a wooden floor
Does it work on the wedding day itself?
Yes. Day mode puts the schedule, seating, dietary requirements, key people and supplier details on your phone, on both plans. It keeps working with no signal, even in a marquee in the middle of a field miles from anywhere.
How do I move from what I use now?
Happy with spreadsheets? Bring them in yourself: Weddings, Guests, Budget and Suppliers each have an Import button, you check a preview first, and you can undo it for 24 hours. Rather not? Send us your files and we move your weddings in for you, free on any plan. The onboarding call is free too.
Can my couples see my costs?
Only what you choose. Each couple's portal shows the modules you turn on, and any budget line can be hidden from them item by item. Couples cannot see each other, and we cannot see your couples either.
Is there a contract?
No. Pay monthly or yearly and cancel any time, from Settings. The 30-day trial needs no card.
