A portfolio site that brings enquiries with carpet area and possession date already filled in, a BOQ builder that prices from your own rate card, stage payments tied to work actually done, a supervisor app for daily site photos, and change orders the client approves in writing before the carpenter starts. For independent designers, studios with their own carpentry teams and turnkey firms running many sites across Mumbai, Navi Mumbai, Thane and Pune.

From the first enquiry to the handover, one set of records for the lead, the quotation, the drawings, the site and every payment.
A fast site that shows completed work honestly, ranks for the localities you serve and asks the questions that sort serious enquiries from window shopping.
One app where homeowners follow their project and your site supervisors report from the flat, even on a weak network.
The office side: leads, quotations, vendors, purchase and project costing, so you know your margin while the project is still running.
A typical residential interior studio in the Mumbai region has two or three designers, one or two site supervisors, a carpentry team paid by contract, and a list of vendors for laminates, hardware, glass, false ceiling, electricals and paint. Enquiries come from Instagram, Google, referrals and the possession list of a new tower, and most of them want a rough price before they will meet. Quotes are built in Excel, sometimes copied from the last similar flat, and sent as a PDF on WhatsApp.
A 2 BHK fit-out has dozens of parts: civil changes, electrical points, false ceiling, modular kitchen, wardrobes, laminates or veneer, hardware, loose furniture, painting and decor. The client asks for a different laminate in week five, the supervisor agrees verbally, and nobody records the price difference. At handover the client refuses to pay the extra, and the final stage payment, often where your margin sits, gets held over a dozen small snags.
Boards and laminates are bought without checking against the BOQ, so the second purchase is never traced. Carpenters bill extra days nobody can verify. A quote sent in January is executed in April at rates that have since moved. And when a client does complain, consumer commissions look at documents. In a July 2026 case reported from Hyderabad, a district consumer commission ordered a refund after records showed agreed items were unfinished at handover.
Infoways, a web, app and software company in Mahape, Navi Mumbai, builds the website, quotation and project tools, and the client and supervisor app as one connected system. A lead from the site becomes a quotation, the quotation becomes a project with stages, and every change, photo and payment sits against that project. Below: how each module works, the GST and site rules it has to respect, how it compares with Excel and ready-made tools, and what to ask any vendor.
Talk to us about your interior design businessEight modules, who uses each one, and the situations that decide whether your team keeps using them after the first month.
Enquiries from the website, Instagram and Meta lead forms, Google ads and referrals land in one list with their source. The form asks flat type, carpet area, scope (full home, kitchen only, renovation), finish level, possession date and locality, so your designer knows before calling whether the job fits. Leads are assigned to a designer, each call or site visit is logged, and a reminder fires when someone has not been followed up. Lost leads get a reason, such as budget, timing or chose another studio, so after six months you know why you lose work.
Solved in your appYour rates live in one library: carcass per square foot by board type, shutters by finish, edge banding, hardware by brand and count, false ceiling per square foot, electrical points per number, painting, labour and transport. The designer picks room items and sizes, the BOQ fills in quantities and rates, and margin is added your way, per line or overall. Each quote is versioned, so revision 3 can be compared with revision 1. Units matter: running foot for lofts, square foot for shutters, numbers for hinges. Formula items, such as sheets needed for a set of cabinets, can come later.
Solved in your appThe final BOQ turns into a quotation PDF with your branding, scope, exclusions, brand list for boards and hardware, timeline and a stage-wise payment schedule, such as booking, design sign-off, material on site, carcass complete, finishing and handover. Exclusions are where disputes start, so they are written plainly: civil work, society deposits, appliances, loose furniture. The quote validity date is printed, because board and hardware rates move. On acceptance, the client signs digitally or on paper and the project is created with every line copied from the quote.
Solved in your appLayouts, elevations, moodboards and 3D renders are sent room by room for approval in the client app, and each approval is stored with the date and the person who tapped it. After sign-off, any change, from a fluted panel behind the TV unit to a different laminate, becomes a change order with its price difference and time impact. The client approves it in the app before the carpenter starts. The site supervisor sees only approved changes. At handover, the final bill is the quote plus approved changes, with nothing to argue about.
Solved in your appMade for supervisors working inside new towers with poor signal. Each day the supervisor checks in at the site, marks the work list (electrical points, ceiling framing, carcass, shutters, painting), adds photos by room and notes problems. Photos are compressed on the phone and upload when the signal returns. Material requests go to the office with the BOQ line they belong to. Carpenter and painter attendance can be marked daily, which helps when a contractor later bills extra days. The client sees a cleaned-up version: photos and progress, not internal notes.
Solved in your appThe office raises work orders to the carpentry team, painter, false ceiling contractor and electrician, drawn from the approved BOQ with quantities and agreed rates. Purchase orders for boards, laminates, hardware and lights are raised against BOQ lines, so a second order for the same item shows up as over budget before it is placed. Vendor bills are matched to orders. Payments to contractors can be tied to work stages, and the panel keeps the vendor’s GST details for your accountant.
Solved in your appWhen a stage is marked complete with photos, the client gets the demand, the invoice and a UPI or card payment link, and the receipt goes out when the money lands. Invoices carry the GST details your CA has set for each contract type, because a turnkey job with material and labour is usually treated differently from a design-only fee. The costing view puts quoted, purchased and paid side by side for each project and each room, so you see the kitchen running over while you can still act, not after handover.
Solved in your appBefore handover, the designer and client walk the flat with the app, room by room, adding snags with a photo: a misaligned shutter, a missing light point, a paint patch. Each snag is assigned and closed with a photo, and the client signs off the list in the app. The final payment demand goes out against the signed list. Afterwards, the project stays in the system with the brand list and warranty details for boards, hardware and appliances, so a hinge complaint a year later goes to the right vendor.

These shape how you quote, invoice and run sites. Tax and building rules change and depend on the facts of each job, so treat this as a map, not advice.
| Term or rule | 1What it means | 2How the software handles it |
|---|---|---|
| Works contract under GST | A contract where you supply both material and labour to fit out or alter immovable property is a works contract under GST, treated as a single supply of services. Tax publications report that turnkey interior work is taxed at 18%. | Each project carries a contract type. Turnkey jobs are invoiced as one works contract supply, with the rate and SAC code your CA sets, not split by hand. |
| Design-only consultancy | A design fee without supplying material is a service on its own, reported at 18% GST. If design is bundled with execution, the contract should say clearly whether material is included. | Design-only projects use their own invoice template and SAC code, and the quote states plainly that material and execution are not included. |
| Place of supply for interior work | For work on immovable property, place of supply is generally where the property is. A Mumbai studio doing a flat in Goa or Bengaluru may need to charge IGST and check registration in that state. | The site address decides the tax type on the invoice. Out-of-state projects are flagged so your CA can confirm the treatment before the first invoice. |
| Blocked input tax credit for clients | Section 17(5) of the CGST Act blocks credit on works contracts for building immovable property, which includes fitting out, other than plant and machinery. Advance rulings have refused credit on interior works for offices and commercial complexes. | Commercial clients often ask about credit. Your invoice wording and line items follow your CA’s advice, and the software does not promise credit the law may not allow. |
| TDS on contract payments | Business clients may deduct tax at source when paying a contractor. The Income-tax Act 2025 replaced the 1961 Act from April 2026 and moved TDS provisions into new sections. | Receipts record TDS deducted by the client separately, so the amount still due is right and your accountant can match it with the tax credit. |
| Written scope, exclusions and change orders | Most interior disputes are about what was included. Under the Consumer Protection Act 2019 a homeowner can complain of deficiency in service, and commissions rely on documents to decide. | The quote lists scope, brands and exclusions. Every later change is a priced change order approved by the client in the app, with date and time stored. |
| Society permission and work hours | Housing societies usually require written approval before renovation, set work hours and ban work on Sundays and holidays. Hours and deposits vary by society. | Each project stores the society approval, its conditions and allowed hours, and the supervisor app shows them so the team does not start drilling at 8 am on a Sunday. |
| Structural changes and municipal permission | Removing or altering walls, beams or columns needs structural advice and, in Mumbai, may need notice to and approval from the municipal corporation, plus the society’s NOC. Drilling into columns or load-bearing walls is unsafe. | Civil items in the BOQ that touch structure are flagged “needs structural approval” and cannot move to work order until the approval document is uploaded. |
| Licensed electrical work | In Maharashtra, the Electrical Licensing Board rules under the Chief Electrical Inspector issue wireman permits and contractor licences. A wireman permit alone does not allow working as a contractor. | The vendor record stores licence details for electricians and electrical contractors, and electrical work orders go only to vendors marked licensed. |
| Debris removal | Debris has to be taken away by a contractor to an approved dumping place. Leaving it on the road or footpath can attract a fine. | Debris removal is its own BOQ line with a vendor and a date, so it is quoted, scheduled and not forgotten. |
GST points are taken from tax publications and advance rulings, which bind only the applicant. Site rules come from municipal and society guidance and vary by city and society. Confirm every rule with your CA, structural consultant and the society before it goes into your templates. We build the rules you approve; we do not decide them for you.
Most studios we meet run on Excel for quotes, WhatsApp groups for each site, Google Drive for drawings and Tally or Zoho Books for accounts. That works up to a point. It breaks when there are more sites than the principal designer can personally track, when two designers quote the same item at different rates, or when nobody can say whether a project made money until weeks after handover.
Ready-made tools are worth a serious look. Houzz Pro is a well-known international option for studios that want leads, proposals and project tracking in one place. Indian products such as Zygn offer leads, BOQs, procurement and client updates built for local studios, and design tools like SketchUp and Foyr handle drawings and renders. Many studios also buy Excel BOQ templates. For a studio of two to five people with a standard way of quoting, a ready tool may be enough, and we will say so.
Your own system makes sense when your quoting is your edge: a rate card with formulas for boards and hardware that no generic tool models well, your own factory or carpentry unit, several branches, or a turnkey business that wants its own client app under its brand. Homeowners also compare you with large online interior brands such as Livspace, HomeLane and Design Cafe, which give clients app updates and payment schedules; your own app lets a smaller studio offer the same comfort. Our guide on custom software vs off-the-shelf covers the trade-off.
You do not need everything on day one. This shows what each route covers well and where it runs out.

All of these come out of the lead list, quotes and project costing. None needs an accountant to work out.
Site visits booked divided by qualified enquiries, by source. It tells you which channel brings people who are serious. Instagram may bring volume while referrals bring visits; your ad money should follow visits, not likes.
Solved in your appOrders signed divided by quotes sent, by designer and by flat type. If one designer converts far below the others, look at their quotes and how fast they send them. If 3 BHK quotes rarely convert, your rates or scope for that size may be off.
Solved in your appAverage days between measurement and sending the quote. Homeowners comparing three studios often go with whoever answers first with a clear number. A rate-card BOQ should bring this down to a day or two.
Solved in your appFor each closed project: quoted value plus approved changes, minus actual purchase, labour and vendor cost. Look at it by room too. Kitchens and wardrobes are where overruns usually hide, from extra sheets, hardware swaps or extra carpenter days.
Solved in your appNumber and value of approved change orders. A high count is not bad if they are priced and approved; it is money you would otherwise lose. A high count of unpriced changes points to a design sign-off that happened too early.
Solved in your appDays between a stage being marked complete and payment received. Long delays often mean the client was not shown proof of the stage, or the stage was defined vaguely. Photos with the demand usually shorten it.
Solved in your appSnags logged per project and days to close the list. It shows workmanship quality by carpenter team and how long your final payment is held. A falling number is the best sign your site checks are working.
Solved in your appGoogle reviews and referred enquiries that came from each completed project. Referrals are the cheapest leads you get. Ask at handover when the client is happiest, and see our guide on [getting Google reviews](/blog/how-to-get-google-reviews.html).
Solved in your appSay you run a studio in Kharghar with two designers, one site supervisor and a carpentry team you trust. The numbers here are only to show the flow. A couple who have just got possession of a 2 BHK in Ulwe see a kitchen reel on Instagram and fill your website form: about 650 sq ft carpet, full home, mid-range finish, possession done, society in Sector 19. The lead lands in the panel and on the designer’s WhatsApp with all of that already filled in.
The designer calls the next morning, visits on Saturday and measures. Back at the studio she opens the BOQ builder, picks an L-shaped kitchen, two wardrobes with lofts, a TV unit, a false ceiling in the living room and the electrical points, chooses boards, laminates and hardware from your rate card, and the quote goes out on Monday with exclusions, brand list, a validity date and six payment stages. The couple compare it with two others and sign, partly because yours arrived first and was clear.
The society approval letter and its allowed hours are uploaded to the project. Layouts and renders go to the client app room by room; the kitchen is approved in two rounds. The supervisor’s app gets the work list, and every evening he uploads photos of the electrical points, the ceiling frame and the kitchen carcass. Purchase orders for boards are raised against BOQ lines, and when the carpenter asks for four extra sheets, the panel shows it as over the BOQ, so the designer checks the cutting plan before approving.
In week five, the couple ask for a fluted panel behind the TV unit. The designer adds a change order with its price and two extra days; they approve it in the app. Each stage demand goes out with photos, and payment comes in by UPI within days. At handover, the snag list catches a misaligned shutter and a missing light point. Both are fixed and closed with photos, the couple sign off in the app, and the final payment arrives that week. The costing view shows the project landed close to the quoted margin, with the overrun traced to the kitchen hardware swap.
We sit with your principal designer and carpentry head to write down how you price a kitchen, a wardrobe, a ceiling and an electrical point: units, board grades, hardware brands, labour and margin. If rates are not agreed internally, this is where it gets fixed, before any screen is designed.
Portfolio pages built from your real completed projects with renders clearly labelled, locality pages for the areas you serve, and the qualifying enquiry form wired into the lead list. Your Google Business Profile is set up with the same project photos.
The rate card goes in, the BOQ builder and quote template are built, and payment stages are defined. Designers start quoting live enquiries in it early and tell us what is slow, while the old Excel stays as a backup.
Approvals, change orders, daily photos, material requests and the snag list, tested by your supervisor on a real site with a weak network. We train supervisors on site in Hindi or Marathi; most need one or two sessions.
Vendor and contractor records with GST and licence details, purchase orders against BOQ lines, and the quoted against actual view. Two or three running projects are loaded in with their actual costs so the numbers mean something from day one.
Before sign-off we check quote totals against your old sheets, GST invoice formats with your CA, payment links settling into your account, role access (a supervisor cannot see margins) and data export. The client app goes to Google Play and the App Store under your studio’s name.
Local SEO for the localities you serve, and maintenance and support for rate changes, new templates and app updates.
Send us your shortlist and one real quote. We will tell you honestly whether a ready tool fits your way of quoting or a custom system is worth it.
Every studio quotes and runs sites differently, so we quote after understanding yours. A portfolio website with locality pages and a qualifying enquiry form is a small project. Adding a lead pipeline, rate-card BOQ, quotation template and stage payments makes it a medium one. A full studio system with the client and supervisor app, change orders, purchase against BOQ, vendor work orders, costing and several branches is a large one.
The biggest cost driver is the quotation logic. A rate library with fixed items is simple. Formulas that work out sheets, edge banding and hardware counts from cabinet sizes, or a link to a cutting-list or factory system, take longer. Other drivers are the number of roles (designer, supervisor, accounts, purchase, vendor), how many running projects must be loaded with actual costs, and whether you want a decor store on the same site. Starting with the website and BOQ, and adding the app when you have more sites, keeps the first phase lean.
Timelines: a portfolio website usually takes 3-6 weeks, most of it gathering good photos and project details. The BOQ, quotation and stage-payment tools take about 6-10 weeks. The full system with apps takes around 3-5 months in phases. See custom software development and our custom CRM development page for how we approach each part.
Do not let software fix your pricing for you. If carcass, shutter and labour rates are not settled with your carpenters and vendors, a BOQ tool will only produce wrong quotes faster. Settle the rate card first, then build it in.
Do not show renders or other studios’ photos as completed work. Homeowners visit real projects and talk in society groups, and trust goes quickly. Label renders as renders and real photos as completed work; ten honest projects beat fifty borrowed images.
Do not skip written exclusions and change orders because the client is friendly in week one. Friendly clients become hard ones when the final bill arrives. A priced change approved in the app protects both sides and your final payment.
And do not build an app if you run one or two sites at a time. A strong portfolio site, a clear quote template and a disciplined WhatsApp routine will do more for you this year. Build the app when the number of sites makes it impossible for you to personally keep every client informed.
Ask us on WhatsApp. A real person from our Navi Mumbai team replies.
Ask on WhatsAppTax publications report that a turnkey interior job, where you supply material and labour, is a works contract taxed at 18%, and that a design-only fee is also taxed at 18% as a separate service. Place of supply is generally where the property is. Confirm the treatment for each contract type with your CA; the software follows their settings.
Often not. Section 17(5) of the CGST Act blocks credit on works contracts for building immovable property, which includes fitting out, other than plant and machinery, and advance rulings have refused credit on interior works for offices. Your client should ask their CA; your invoice should not promise credit.
Common stages are booking, design sign-off, material on site, carcass or civil complete, finishing and handover. What matters is that each stage is defined by work you can show in photos. The app sends each demand with photos of that stage, which usually gets payment faster.
Yes. Your rates for carcass, shutters, laminates, hardware, ceiling, electrical points and labour sit in a rate library with your units. The BOQ builder fills in quantities and rates, you add margin your way, and any line can still be edited before sending.
Write scope, brands and exclusions in the quote, and turn every later change into a priced change order the client approves in the app before work starts. The final bill is then the quote plus approved changes. Consumer commissions rely on documents, so this record protects you as well as the client.
Most housing societies require written approval before renovation and set work hours, often with no work on Sundays and holidays. Structural changes may also need municipal permission in Mumbai. The software stores the approval and allowed hours on each project, but check your client’s society rules every time.
Only with a structural engineer’s advice, the society’s NOC and any municipal permission required. Drilling into columns or load-bearing walls is unsafe. In the BOQ we flag civil items that touch structure, and they cannot go to work order until the approval is uploaded.
Your supervisor uploads dated photos room by room from his app each day. The client sees them in their own app, along with which stage is complete and which payment is next. Internal notes and rates stay hidden from the client.
Yes. Photos are compressed on the phone and queued, and upload when the signal returns. This matters in new towers where the network inside the flat is often weak.
For a small studio with a standard way of quoting, a ready-made tool may be enough, and it is quick to start. A custom system makes sense when your quoting formulas are your edge, you have your own factory or several branches, or you want a client app under your own brand.
Yes. You keep designing in SketchUp or your usual tool and upload renders, walkthrough videos or 360-degree panoramas. The app shows them for approval; it does not replace your design software.
Yes. When a business client deducts tax at source, the receipt records it separately, so the balance due is right and your accountant can match it. The Income-tax Act 2025 moved TDS provisions to new sections from April 2026, so your CA should confirm the current section.
Yes. A store can sit on the same website with products, cart, UPI and card payments, and courier shipping. If you only sell to project clients, items can be added straight into their quotation instead.
Client names, phone numbers, addresses and photos of their homes are personal data under the DPDP Act 2023. We build consent on enquiry forms, access by role so vendors see only their work order, a setting to remove old site photos, and logs for every export.
A portfolio website usually takes 3-6 weeks. BOQ, quotes and stage payments take about 6-10 weeks. The full system with client and supervisor apps takes around 3-5 months in phases.
