A practice management ecosystem for design firms

Design school teaches design. Nobody teaches the fee letters, work orders, trackers and office systems a real practice runs on. Arkdox fills that gap.

Who it's for, and what gets in the way

Fresh graduates
Little exposure to real-world documentation, workflows and office management.
Small firms
No standard processes, so deliverables vary and repetitive paperwork eats the week.
Architects
Creative, billable hours lost to formatting, coordination sheets and admin.
Interior designers
Need ready workflows, structured project systems and polished client-facing documents.
Freelancers and consultants
Need reliable contracts, proposals, invoices and letters that protect their business.
Growing studios
Need professional formats they can use tomorrow, without building systems from scratch.

What Arkdox gives you

  • Time-saving professional templates and systems
  • Standardised office documentation workflows
  • Ready-to-use business and project management resources
  • Sharper professionalism in front of clients
  • Structured operations for architecture and interior practices

Stop drafting from scratch. Start running a real practice.

Arkdox helps architects and interior designers focus on design, execution and growth, with less stress from repetitive documentation and unstructured office processes.

Why practices choose Arkdox

Free templates get you a blank page. Building your own costs weeks you could spend designing. Arkdox sits in between.

Drawn to a standard

Every file is set up the way a careful practice would set up its own, so what you send clients looks considered before they read a word.

Editable, not locked

Everything opens in Word, Excel or PowerPoint. Add your logo, change clauses, rename sheets. Nothing needs special software.

Professional layouts

Margins, heading hierarchy and reference numbering follow one consistent professional standard across every kit, so a letter or agreement reads cleanly, looks like it came from one office and files neatly.

Written for Indian practice

GST workings, contractor billing and fee benchmarks set against Mumbai and Pune market rates, with formulas checked cell by cell.

Who is behind Arkdox

Built by an architect, for working practices

“Most practices don't struggle with design. They lose time and money to unclear scope, unsigned fee letters and bills nobody is tracking. Arkdox is the paperwork we wish we'd had on day one.”

Arkdox is built by an architect-led team in Pune, the people behind Aidekdoc, a resource library and store used by design practices across India. Every Arkdox document started on a real project, with real clients, contractors and approvals, and was reworked until everyone involved could follow it without a phone call.

Tested on real jobs

Fee letters, work orders and trackers come from projects we have run, not from generic templates.

Written for Indian practice

GST, UDCPR references, milestone billing and local market rates are part of the design, not an afterthought.

Accountable

A named practice stands behind every file. If something doesn't work for you, write to us and we will fix it.

Arkdox and Aidekdoc. Arkdox is our guided practice system: the documents you need, organised by project stage, with a toolkit that walks you through them. Aidekdoc is our wider resource library and store. ARKDOX practice resources are powered by AIDEKDOC.

Questions, answered

Everything about buying, files, licenses and support. Search, or browse by topic.

Buying and payment

How do I pay, and do I get an invoice?

Pay securely at checkout with UPI, cards or net banking. Your download link and a GST invoice arrive by email straight after payment.

Can the invoice show my firm's name and GSTIN?

Yes. Add your firm name and GSTIN at checkout. If you forget, email us within 30 days with your order number and we'll reissue the invoice.

Is my payment secure?

Payments are handled by a PCI-DSS compliant payment gateway over an encrypted connection. Arkdox never sees or stores your card, UPI or bank details.

Do you offer bundles or studio pricing?

Buying three or more kits, or equipping a larger team? Write to us and we'll send a bundle quote.

Files and software

What do I actually receive?

A ZIP download of editable Microsoft Word, Excel and PowerPoint files, organized in folders by project stage. You can open them straight away with no setup.

Which software do I need?

Microsoft Word, Excel and PowerPoint 2016 or later, on Windows or Mac. Word and PowerPoint files also open in Google Docs and Slides. Excel workbooks work best in Microsoft Excel, as some formulas and formatting behave differently in Google Sheets, Numbers or LibreOffice.

Can I put my own studio branding on the documents?

Yes. Logos, colors, letterheads and footers are all editable. Replace ours with yours once and save the files as your own templates.

Do the Excel workbooks handle GST?

The Interior Fit-Out Cost Estimator and the Advanced Practice Control & Quality Assurance Toolkit include GST workings in quotations, invoices and contractor billing. Check rates against current notifications before issuing invoices.

Are the agreements legally vetted for my state?

They are professionally drafted starting points. Have a lawyer review contracts for your jurisdiction and the size of the project before you rely on them. See our Disclaimer.

License and use

Can I use the kits for more than one project?

Yes. Use them on every project your studio takes on, for as long as you like.

Can my team use the files?

Yes, anyone working within your firm can use them. For larger teams, ask us about a studio license.

Can I share documents with clients and contractors?

Yes, share completed documents such as a signed agreement or a filled-in BOQ. Please don't share, resell or upload the blank templates. The full rules are in our Terms.

Support

I lost my download link. What now?

Email contact@arkdox.com with your order number or the email you used at checkout, and we'll send a fresh link.

Can I get a refund?

Because files are delivered instantly, refunds cover duplicate payments, faulty files we can't fix and wrong kits that haven't been downloaded. Read the full Refund policy.

Can you customize a kit for my studio?

Tell us what you need through the contact page and we'll let you know if we can help and what it would cost.
