Sound familiar?
The billing problems interior designers run into.
🎨
Design fees, procurement, and reimbursables all need separate lines
A single project has design fees, furniture sourced with a markup, trade-only purchasing, contractor coordination fees, and expense reimbursements. Lumping it into one number confuses clients and gets disputed.
📐
Retainer billing requires precision
You bill a retainer at project start, apply it to the final invoice, and the math has to be exact. Doing this in a Google Doc or Word template is error-prone and looks unprofessional.
🛋️
Procurement tracking lives in too many places
Trade purchases tracked in a spreadsheet, design fees in your email, expense reimbursements in a notes app. No single place to pull an accurate invoice from.
⏳
Projects drag on and invoices go stale
A 6-month renovation means invoicing in phases. Without a system, you lose track of what's been invoiced, what's been paid, and what's still outstanding.
📬
Chasing client payments kills momentum
You send the invoice, they say they'll pay next week, next week comes and goes. Following up on money is uncomfortable and takes time away from design work.
🏷️
The invoice doesn't match the brand you built
You've created a premium client experience, then sent an invoice that looks like it was made in Excel. The disconnect undermines the perception of value.
The fix
Invoicing built around how interior design projects actually work.
📋
Proposal-to-invoice in one click
Build the detailed estimate with all fees, procurement markups, and reimbursables. Client approves it. Convert to invoice with one click when the project milestone hits.
💼
Separate line items for every billing type
Design fee, procurement markup, expense reimbursement, and contractor coordination all on the same invoice as separate, clearly labeled line items.
🔁
Retainer billing with milestone tracking
Invoice the initial retainer, then create milestone invoices as the project progresses. Clients always know exactly where they stand.
🎨
Branded invoices that match your studio
Add your logo, brand colors, and business details. Clients see your brand — not a generic billing tool — when they open the invoice.
💸
Online payment via card or ACH
Upgrade to Pro and clients can pay directly from the invoice link. Card, ACH bank transfer, or Apple Pay. No checks, no delays.
🔔
Automatic reminders on overdue invoices
Stop the uncomfortable "just checking in on my invoice" emails. Reminders go out automatically so you only reach out when you actually need to.

From proposal to paid — without the admin chaos.
Create the project estimate

FAQs
Common questions from interior designers.
What is the best invoice software for interior designers?
WaffleInvoice is built for service businesses including interior designers. You can create detailed invoices with design fees, procurement markups, and expense reimbursements as separate line items, convert proposals to invoices in one click, and collect payment online. The free plan covers 25 invoice emails a month with no credit card required.
How do I invoice for design fees and procurement separately?
Add each billing type as its own line item on the invoice — design fee at your flat or hourly rate, procurement as item cost plus markup, and reimbursables as actual cost. Each line has a description, quantity, and unit price. Clients see a clear breakdown of every charge.
Can I send a retainer invoice to my design clients?
Yes. Create an invoice for the retainer amount, send it before the project starts, and collect payment online (on Pro). For milestone billing, create subsequent invoices as the project progresses and apply the retainer credit as a line item adjustment on the final invoice.
How do I handle billing for multi-phase design projects?
Create an initial estimate with the full project scope. Convert portions of it to invoices at each milestone. WaffleInvoice tracks which invoices are paid, pending, and overdue, so you always know where every phase of the project stands financially.
Is WaffleInvoice free for interior designers?
Yes. The free plan gives you 25 invoice emails per month with unlimited invoice and estimate creation, branded invoices with your logo, and client approval workflows. No credit card required. Upgrade to Pro ($19/mo) for unlimited sends, online payments, and automatic reminders.
