Welcome to Programa's invoicing software for interior designers — the fastest way to go from project work to paid invoice without the admin. Create professional invoices directly from your schedules, time tracking entries, and custom line items, with descriptions, quantities, markups, and pricing pulled across automatically.

Programa's interior design invoicing tools are built for studios that need billing to match how design projects actually move. Split any invoice into up to six instalments with custom names, due dates, and amounts — structured around real project milestones like deposit, procurement, and final delivery. Clients see exactly what they owe and when, and pay each stage individually.

With built-in payment collection through Programa Pay, clients pay by card or bank transfer through a branded payment portal. No separate logins, no third-party portals, and no friction. Chargeback protection is included on every payment processed through the platform, so your studio is covered if a dispute arises.

Every invoice reflects the quality of your studio's work. Add your logo, include product images from your schedules, and present a clear, professional breakdown of what the client is paying for. Interior design billing has never looked this considered.

Programa's invoicing integrates directly with QuickBooks and Xero, with central account mapping and custom tax rates that sync accurately per line item. Keep your accounting tool as your system of record while eliminating the double-handling that eats into your week.

Whether you run a solo practice or a mid-size studio, Programa's invoicing and billing software for designers removes the manual work between project delivery and getting paid — so you can focus on design, not data entry.
