New feature
Invoicing and payments, rebuilt around how studios bill
Deposit-then-balance invoicing, billing straight from procurement, automatic payment reminders, offline payment recording, client statements, and card or bank payment in the portal.

Mortar now carries a complete billing layer, shaped around the way design studios bill rather than the way generic invoicing tools assume.
- Payments that match reality. Record a bank transfer, cheque, or cash payment against an invoice, in full or in part, and edit or void a mispunched entry. Recording an offline payment carries no Mortar transaction fee. Online payments only ever charge what's still owed, so a client who has paid a deposit can't be double-charged.
- Invoices you can work with. Edit a draft's lines, dates, and notes without voiding it. Every invoice has a detail page with its payment history and activity trail. Resend a lost invoice, choose recipients and cc with a personal note and a live preview, and search the list in plain language ("unpaid invoices over $5,000 from last month").
- Get paid without chasing. Automatic reminders before and after the due date, written warm, always stating the current amount owed. Turn them on studio-wide or pause them per invoice.
- Card or bank transfer in the portal. Clients pay through your connected Stripe account by card or by bank transfer (US ACH and AU BECS). In the common case the payment link doesn't expire.
- Deposit up front, balance on delivery. Create a deposit invoice as a percentage or fixed amount; once paid, apply it to the balance invoice and Mortar adds the credit line with accurate tax handling.
- Bill straight from procurement. Every item shows its billing status; select a room's approved items or everything received and generate an invoice in two clicks, with protection against billing the same item twice.
- Client statements. A per-client account view (invoiced, paid, outstanding, deposits held) with a branded PDF statement for any date range. It's a studio tool you generate and share, not a client login.
