Devquiry
Practical software tools for service-based businesses — from clinics and CA firms to agencies and local teams.
A small studio in Indore building affordable business software for CAs, clinics, agencies and service providers. Client portals, filing trackers, clinic systems, and founder-release tools like OptMail Pro — built for real workflows, not vanity dashboards.
From CA portals to billing systems, running in production today.
The ones who shipped with us, stay with us every month.
From kickoff call to your team using it live in production.
Inquiries, bug reports, feature requests — we don't ghost.
Founder-release tools. Real utility.
Alongside custom CA and clinic systems, DevQuery Labs releases practical self-hosted tools at founder pricing. Early users get value now; we get real feedback to improve the product.
A self-hosted email campaign system for agencies, CAs, clinics, freelancers and service businesses. Install once, connect your own SMTP, manage client campaigns, track reports, handle unsubscribes and bounces, and keep your data under your control.
Runs on your system/VPS with your data.
Client workspaces, reports and portal access.
Gmail, Workspace, SES, Brevo, SendGrid, Mailgun.
Unsubscribe, suppression list, bounces and audit logs.
Lifetime use of the purchased version, 1 year of updates, self-hosted package, license key and buyer docs. Limited founder seats while we collect feedback.
OptMail is for permission-based email communication — not spam, phishing, scraped lists or inbox guarantees.
Tools for service businesses. Built practical.
Custom tools for CAs and clinics, plus DevQuery Labs products for marketing, automation and client communication.
Running a CA firm means managing dozens of clients, hundreds of documents, and filing deadlines that never stop. We build you a private portal where your clients can upload documents, track their GST and ITR status, and you can manage everything from one clean dashboard. No more WhatsApp document chaos. No more missed deadlines. Just a system built exactly for how your firm works.
Today's Filings
● LiveHow we actually work.
Three steps from "we should fix this" to "we use it every day". No decks. No surprises.
We understand your practice — how you actually work, what's breaking, what you need. No pitch. Just listening. 30 minutes.
Our team designs and ships your tool. You see weekly progress. You give feedback. We ship fast without cutting corners.
Once live, we don't disappear. Updates, fixes, new features — we're here every month. That's what the retainer covers.
What we will & won't build.
We say no to most projects. Here's exactly when we're the right team — and when you should hire someone else.
You run a service business that's outgrown spreadsheets, WhatsApp chaos, or rented SaaS tools.
- You have 20+ clients / patients and tracking is becoming chaos.
- You want a real tool — not a no-code Frankenstein.
- You can talk to us for 30 mins a week during the build.
- You'd rather pay ₹5–7K/month than hire an in-house dev.
- You want one team that ships AND maintains the software.
You need something outside our wheelhouse — and we'll tell you.
- You need a mobile app (we only do web — for now).
- You want a full ERP replacement at enterprise scale.
- Your timeline is "we needed it yesterday".
- You want us to compete on price with a college freelancer.
- You haven't decided what you actually need yet.

Things we've shipped.
A small but real catalogue. Each one running quietly in a practice somewhere in India.
GST & ITR tracking for 80+ clients with WhatsApp reminders.
Appointment booking + patient records for a 3-doctor clinic.
A dashboard our CA-firm clients use to never miss a deadline again.
Self-hosted email campaign system with SMTP, tracking, client reports and bounces.
What clients actually say.
Real quotes. No marketing fluff.
Honestly the WhatsApp chaos was killing us. They built exactly what I described. My clients use it without complaint — which says everything.
Three weeks from "I have an idea" to my receptionist using it Monday morning. The maintenance retainer is the best part — they actually pick up the phone.
We almost bought an enterprise tool for ₹3L/year. Devquiry built us something better for a fraction. Small team, no nonsense, ships what they promise.
Questions, answered.
The stuff every prospect asks. Saves us both 10 minutes.
Yes — fully. We hand over the GitHub repo, database, and deployment access. The retainer is for our service, not to hold your software hostage.
No contract, cancel anytime. Your software keeps running. We just stop being on call for fixes and updates. Most clients stay because it's cheaper than losing the time.
Usually yes — if there's an API or export option. We've done Tally syncs, Razorpay, Google Calendar, and WhatsApp Business API. We'll confirm on the discovery call.
PostgreSQL on Railway. HTTPS everywhere, encrypted at rest, daily backups. You get admin access — we don't read your data, we just keep it running.
If scope grows mid-build, we tell you before billing more. If we underestimated — that's on us, no extra cost. We scope tight on purpose so this rarely happens.
No. CA and clinic tools are our core custom-service focus, but DevQuery Labs also releases practical tools for agencies and service businesses — starting with OptMail Pro.
It is a limited DevQuery Labs founder release. Early users get lifetime access to the purchased version at a lower price, and we get real-world feedback, testimonials and product validation.
No. OptMail Pro is self-hosted. You install it locally or on your VPS, connect your own SMTP provider, and keep control of your data. Optional paid setup is available.
We're Devquiry.
Three developers from Indore, building practical software for service-based businesses.
Devquiry is run by Abhishek and two teammates. We started because we saw a gap nobody was filling — small businesses in India were either stuck with bloated enterprise software priced for Mumbai HQs, or duct-taping everything together on WhatsApp and Excel.
We build the middle ground. Custom software that fits your budget, your team, and your way of working. Our custom builds focus on CA firms and clinics, while DevQuery Labs releases smaller self-hosted tools like OptMail Pro for agencies and service businesses.
If you want a long sales pitch, we're probably not your studio. If you want a working tool in three weeks, hello.
Let's build it.
We reply within 24 hours — on WhatsApp or email. Your choice.
Tell us about your practice.
The more specific you are, the better the first call goes. Team size, what's breaking, what you'd love to fix — that's plenty.
