One list for the budget, the schedule, the client and the orders.
Add each product once. Mortar keeps every view of it in step, so the spreadsheet, the PDF and the email thread never disagree again.

Sound familiar?
One sofa.
Five places to update it.
None of these are design problems. It's one sofa, typed into five places that don't talk to each other.

Did I change the price in the budget, or only in the schedule?

What your client sees
A portal your clients will open. Your pricing stays yours.
No account, no app.
One link from you, with your logo and colours, not ours.
Decisions that stick.
Every approval, comment and option pick is saved on the item with the date. No "we never agreed to that."
Pricing your way.
Show full prices, room totals only, or no prices. Hide supplier names. Your cost and margin never appear anywhere client-facing.
Totals that move with them.
As they choose, the budget updates on screen.

Quotes, orders, deliveries
Know what's ordered, what's late and what's paid for.
Quotes without the copy-paste.
Forward a supplier's quote, attachments and all. It lands in the right project as lines you can accept.
Purchase orders from approved items.
Pick the items, choose the supplier, raise the PO. Supplier payments tracked against it.
Lead times that warn you.
Order date, lead time and expected arrival on every item. Mortar can look up the lead time and marks it as an estimate. Anything running past install gets flagged.
For the studio
Let the team in. Keep the margins yours.
Invite your assistant, your PM, a contractor. Team members can do the work without ever seeing cost or margin: not in lists, not in history, not in exported PDFs, not in the AI assistant's answers.
The AI assistant works inside your projects (“add this to the primary bedroom”) and asks before it does anything sensitive.
Bring what you have
Start with the spreadsheet you already have.
Import your budget or FF&E spreadsheet (including our free templates) and Mortar builds the rooms and items for you. Map the columns once and it remembers. Pinterest boards come in too.

Worked example
Your client pays a $10,000 invoice by bank transfer. The total fee is $15 — Stripe's $5 and Mortar's $10 — and it's capped there, no matter how large the invoice. On a card, the same invoice is $330.30.
On a $40,000 invoice by bank transfer: Mortar $15 · Studio Designer $25 · Materio $30.
Australian studios: from 1 October 2026, card surcharging is banned in Australia, so card-fee pass-through to clients isn't available for AU merchants. Bank-transfer fee pass-through is unaffected.
Free for every designer: a portfolio page with a link back to your site.
