Invoicing Software for Interior Designers
Bill design fees by phase, handle procurement with deposits and markup, and keep every invoice tied to its project. The fee structure that confuses clients becomes a clean, documented billing thread.
Design fees, billed by phase
Interior design billing is phased by nature: concept, design development, procurement, installation. Scheduled invoices per phase keep cash flow aligned with the work — the 50% concept deposit, the DD milestone, the final at install — each sending and reminding automatically.
Hourly arrangements bill from tracked time with rates by role, so principal hours and junior-designer hours itemize correctly. The client sees the breakdown; you stop discounting by accident.
Procurement is a cash-flow trap without deposits
Furniture procurement means fronting five-figure orders unless deposits lead. The standard protection: invoice 100% of product cost (or cost-plus deposit) before ordering, with your trade discount and markup structure applied per your letter of agreement. Invoices document each item against the order.
Freight, receiving, storage, and white-glove delivery bill as line items — the costs clients forget exist until they're itemized. Documented pass-throughs are the difference between a margin and a dispute.
One project, one billing thread
A whole-home project generates dozens of invoices across phases and purchases. Keeping them on one project thread means the client's "what have we paid so far?" is a report, not an afternoon of spreadsheet reconciliation.
Change requests — the third sofa option, the swapped tile after ordering — bill as documented additions with the decision trail attached, which is what keeps scope honest in a business where taste evolves mid-project.
What to look for in interior design invoicing software
Design billing mixes professional fees with product procurement — two different billing problems. Require:
- Phase invoicing for fees: concept, design development, procurement, installation.
- Procurement deposits before ordering, with markup or cost-plus structures applied per item.
- Pass-through line items for freight, receiving, storage, and white-glove delivery.
- A single project billing thread, so 'what have we paid so far?' is a report.
- Documented change billing for the swapped tile and the third sofa option.
How Agiled compares to Houzz Pro, Studio Designer, and QuickBooks
The design-specific platforms go deep on procurement: Houzz Pro (from about $85/month) bundles sourcing and client management; Studio Designer (from about $64/user/month) is the accounting-grade standard for established firms; QuickBooks handles the books but knows nothing about FF&E. For high-volume procurement practices, Studio Designer's depth is real.
Agiled fits design studios that want fees, procurement billing, projects, and client records in one flat-priced system — free to start. The selection approval, the deposit invoice, and the freight pass-through live on the same project the design fee bills from.
