Billing software for design & build firms
Billing, staged the way the work actually happens.
Interior designers, architects, and contractors don't bill like retail — they get paid across project milestones. archBill turns that into a system: staged invoices, correct GST, and one dashboard for what's owed.

How it works
From setting up a project to getting paid — four steps, no spreadsheets.
Add your project
Set up the client, contract value, and payment stages — Stage 1, Stage 2 — each with its own amount and due date.
Bill a stage
One click generates a GST-correct tax invoice or estimate, branded with your logo and bank details.
Send it
WhatsApp or email, straight from the bill, in your own wording — no separate app to switch to.
Track it
The dashboard shows what's paid, what's overdue, and what's coming next, across every project.
What it does
Staged billing
Every project gets auto-numbered stages — Stage 1, Stage 2 — each with its own description, amount, and due date, tied to real milestones.
GST, handled
CGST/SGST or IGST calculated automatically from firm and client state. Switch to a plain estimate when GST doesn't apply.
Branded bills
Every PDF carries your logo, business name, contact details and bank account — not a generic template.
Sent in one tap
WhatsApp or email, straight from the bill, in your own wording.
Full edit history
Change an amount or date after a bill is issued and it's logged — who, when, and what it used to say.
One dashboard
Outstanding dues, this month's collections, overdue flags, and a six-month income trend, at a glance.

Frequently asked questions
What is archBill?
archBill is billing and invoicing software built for interior designers, architects, and construction contractors in India. It bills projects in payment stages instead of a single invoice, with GST calculated automatically.
How does staged billing work?
Each project is broken into auto-numbered stages — Stage 1, Stage 2, and so on — with its own amount and due date. You bill a stage as it's completed instead of invoicing the whole contract at once.
Is archBill GST compliant?
Yes. archBill automatically calculates CGST and SGST, or IGST, based on your firm's and client's state, and can also generate non-GST estimates when that's all you need.
Can I send bills over WhatsApp or email?
Yes. Every bill can be sent directly from archBill over WhatsApp or email, in your own wording, without switching to another app.
Who is archBill for?
Interior designers, architects, renovation contractors, and building or construction firms who bill clients across project milestones rather than a single transaction.
