Everything that could go into planning a wedding, with the month it's usually done. Tick what applies to you: the portal hides the sections you don't need, puts the rest on your calendar at the typical time, and tells you what's next.

Real people on a schedule that tightens as the day approaches: Caitlin and Shanay Burrows, a seasoned wedding and special events coordinator. Included with Tier 3; private time with Shanay is extra, per session.

One page for the money. Pick what makes your wedding a wedding, put a supplier and a cost against each, say who's paying — and the budget, the supplier sheet and the calendar all update from the same numbers. Nothing is typed twice.

Everything printed or sent, in the order guests see it: save the dates, invitations, then the on-the-day pieces — menus, place cards, order of service, signage — and thank-you cards after. Quantities come from the guest list; the cost rolls into the budget under Stationery.

The look of the day in one place: your palette and three words, the mood board suppliers work from, then the room itself — tables, where the flowers, cake and band go, and who sits where. Speakers are flagged so they're never seated at the back.

Every guest on their own line with their household group beside them, so numbers and meal choices are exact. Tags — speech, bridal party, hen, stag, access, allergy — follow each person onto the table plan, the floor plan and the right emails.

The hen and the stag, planned by the people who should be planning them. You set the dates you're free, the budget per head and the "please don't" list; one email each to the maid of honour and best man carries the tagged guest list with it.

The personal bits: your vows, with a structure that works; thank-you gifts for the people standing beside you, costed straight into the budget; and your private pages — the dress for Ada, Rowan's corner for Rowan — that the other can't see.

From the children on the guest list and their ages, a suggested number of nannies, when they're needed and what to brief them on — with the cost dropped into the budget under Childcare.

The day minute by minute, with who's in charge of each moment — friends and family included — the photo list, and every file the venue asks for. Tagged guests get told in the final email when they'll be called.

After the day: every guest's photos in one gallery, thank-yous matched to each gift with a photo attached, and — if you'd like — the best of everything as a printed book. Then the portal data is deleted and the website is yours as HTML, for life.
