Wave gets recommended a lot for one reason, it's free, and when you're a young studio watching every rupee, free accounting and invoicing software sounds like a gift. So if you're weighing Wave for your interior or architecture studio in India, let me give you an honest, operator's-eye comparison of Designa and Wave, because "free" and "right for your studio" are not the same thing, and the gap between them is where a lot of Indian studios quietly lose time and money.
I'll be fair to Wave, it's a clean, capable accounting tool for the market it was built for. I'll also be honest that it was built for North America, it does none of your design work, and it can't produce the GST invoice an Indian studio actually needs.
Wave is an accounting tool, not a studio tool
Let me set expectations right at the top, because this is where the confusion lives. Wave is bookkeeping and invoicing software, so it handles accounts, invoices, receipts and, in the US and Canada, payments and payroll. It's a back-office tool, and it has no idea what an interior design project is. There's no lead capture, no room-by-room furniture and finish spec, no mood board a client approves, no procurement chain, no purchase orders, no site updates, no milestone billing across a project. All of that, the actual studio, lives somewhere else entirely, which means Wave was only ever going to be one tool in a stack of five, and the stack is the problem you were trying to solve. I made that case in full in why one connected system beats five disconnected tools.
Designa is the opposite shape. The accounting is the tail end of the work, not the whole tool. You capture the enquiry, spec the project room by room, get the mood boards approved in a branded portal, raise the quote, run procurement to delivery, bill the milestone, and only then does the money flow into your books, and it syncs to Tally and Zoho Books so your CA works where they already do.
The GST invoice gap, field by field
Here's the part that catches Indian studios off guard, because even at the one job Wave is supposed to nail, invoicing, it can't produce a compliant Indian tax invoice. Wave's sales-tax handling is built for US and Canadian tax, so it won't give you the fields a GST invoice legally needs. Let me show you exactly what's missing.
| GST invoice requirement | Wave | Designa |
|---|---|---|
| Your GSTIN on the document | Not built in | Yes |
| CGST/SGST vs IGST split by place of supply | No | Yes, decided automatically |
| HSN codes for furniture and finishes supplied | No | Yes |
| SAC codes for the design fee | No | Yes |
| Continuous, gap-free invoice numbering series | Generic numbering | Yes, maintained automatically |
| "Tax Invoice" format under CGST rules | No | Yes |
| Razorpay (UPI) collection | US/Canada payments only | Yes |
Look at that column of "No" and it's clear, a Wave invoice would get bounced back by your client's accountant, because without the GSTIN, the right tax split and the HSN and SAC codes, your client can't claim input credit on it. Designa raises that compliant invoice in one click from the approved quote, and if the pricing side is what you're really weighing, how Designa's rupee pricing works is worth a read.
Free isn't free once you count the leaks
The seductive thing about Wave is the price, and I get it, but let me be blunt about what "free" actually costs a studio. If your accounting tool does none of your design work, your specs and approvals and procurement stay in spreadsheets and WhatsApp, and that's where margin leaks, a PO at the wrong rate, an approval nobody recorded, a delivery that slipped. And if the invoice it produces isn't GST-compliant, your payments get delayed while accountants query them. So the tool costs nothing and the workflow around it costs you plenty, which is the same trap I described comparing Designa vs a scheduling tool like Microsoft Project, a capable product aimed at the wrong problem.
Designa is one flat founding price for your whole studio, billed in rupees, with unlimited free client logins, and yes there's a price on it, but it replaces the stack, so the honest comparison isn't "free versus paid", it's "one tool that runs the studio versus five tools plus the gaps between them".
What your billing tool must do in India, free or not
- Put your GSTIN on the invoice
- Split CGST/SGST or IGST correctly by place of supply
- Carry HSN codes on goods and SAC codes on the design fee
- Keep the invoice number series continuous and gap-free
- Collect via Razorpay so clients pay by UPI
- Connect to the design work, not sit off to the side
So which one fits you?
Choose Wave if you're a US or Canada based freelancer who only needs simple bookkeeping and generic invoices, and design specs, procurement and GST aren't your concern. For that person, free and clean is a fair deal.
Choose Designa if you run a design studio in India and you want the whole studio plus a compliant GST money loop in one place, at one flat rupee price with unlimited free client logins. If you're comparing across categories, my Designa vs SketchUp comparison covers the drawing-tool side, my Designa vs Programa piece covers a design-native tool, and the best software for interior designers in India guide and the best Houzz Pro alternative for Indian studios round it out.
If you're building a studio you want clients to trust, running a compliant back office matters, and the professional bodies most Indian designers align with, the Institute of Indian Interior Designers and the Council of Architecture, all assume you're operating above board on tax.
Frequently asked questions
Can Wave produce a GST-compliant invoice for India?
No, Wave's tax handling is built for the US and Canada, so it can't carry your GSTIN, the correct CGST/SGST or IGST split, or HSN/SAC codes, whereas Designa does this in one click.
Is Wave really free, and is that enough for a studio?
Wave's core invoicing and accounting are free, but it does none of your design specs, approvals or procurement and can't raise a GST invoice, so an Indian studio still needs other tools around it.
Can I collect UPI payments through Wave?
No, Wave's payments are limited to the US and Canada, while Designa collects via Razorpay so Indian clients pay by UPI or card on the invoice.
Does Designa replace an accounting tool like Wave?
Designa runs the studio and raises compliant GST invoices, then syncs to Tally and Zoho Books, so your accountant keeps their ledger while you stop re-keying invoices.
