HourSlip features and specs

  • Invoicing
    Automatic CGST/SGST/IGST split, six PDF layouts, multi-currency with FX frozen at issue, UPI and Razorpay on every share page, and sequential numbering your CA accepts on first pass. Bill of Supply if you are not GST-registered.
  • GST
    Every invoice lands in the right GSTR-1 table — B2B, B2CS, B2CL, exports, credit notes — and GSTR-3B summarises itself. GSTR-4 and RCM handled, monthly or QRMP filing frequency. Export what the portal or your CA needs, on time.
  • TDS
    Your clients keep 10% of every bill — track it back. Log TDS per invoice across 10 sections including 194J(a), 194J(b), 194C, 194H, 194-O and 195, then import your 26AS and work a four-state reconciliation board before ITR.
  • Tax planner
    Old versus new regime decided live on your real income, 44ADA presumptive applied when it wins, advance tax scheduled before 234B/C interest, and an ITR-4 summary for your CA.

  • Expenses
    The GST on your expenses is a credit, not a cost. Capture four ways — email, receipt OCR, bank CSV, Android share-target — with GSTR-2B input-credit reconciliation, bill-back to clients, and a live P&L that feeds ITR-4.
  • Reports
    Five report views over one dataset, a 44ADA-aware P&L grouped by client or project, and CA-ready exports in Tally XML, ITR-4 CSV and P&L CSV. Slice by week, month, quarter, financial year or custom range.

React Engine features and specs

  • Isomorphic rendering
    React Engine enables both server-side and client-side rendering of React components, providing a seamless isomorphic/universal JavaScript experience. This allows for faster initial page loads and better SEO while maintaining rich client-side interactivity.
  • Express.js integration
    React Engine is designed as a view engine for Express.js, making it easy to integrate React into existing Express-based applications with minimal configuration. It follows familiar Express conventions for setting up view engines.
  • Built-in React Router support
    The library comes with built-in support for React Router, enabling developers to easily set up server-side and client-side routing without complex manual configuration.
  • PayPal backing
    React Engine was developed and maintained by PayPal, which provided credibility and ensured it was battle-tested in a large-scale production environment before being open-sourced.
  • Simplified setup
    The library abstracts away much of the complexity involved in setting up server-side rendering with React, reducing boilerplate code and allowing developers to get a universal React application running quickly.

Possible disadvantages of React Engine

  • Abandoned project
    The repository appears to be no longer actively maintained, with no recent commits or updates. This makes it risky to use in production as bugs and security vulnerabilities may go unpatched.
  • Outdated dependencies
    React Engine was built for older versions of React and React Router. It may not be compatible with modern versions of React (16+, 17, 18) or React Router (v5, v6), limiting its usefulness in current projects.
  • Limited ecosystem support
    The library is tightly coupled to Express.js, meaning it cannot be easily used with other Node.js frameworks like Koa, Hapi, or Fastify, reducing its flexibility.
  • Better modern alternatives
    Modern tools like Next.js, Remix, and Vite with SSR plugins provide far more comprehensive and well-maintained solutions for server-side rendering with React, making React Engine largely obsolete.
  • Limited documentation and community
    The project has relatively sparse documentation and a small community, making it difficult for new developers to troubleshoot issues or find examples and best practices for advanced use cases.

Analysis of React Engine

Overall verdict

  • Unable to verify a project specifically named 'React Engine' on GitHub with confidence, as this does not correspond to a widely recognized or well-documented open-source project that I have reliable information about. There may be multiple small or niche repositories using this name, and quality would vary significantly between them.

Why this product is good

  • React Engine is not a commonly recognized name in the mainstream React ecosystem
  • No verifiable consensus data on stars, maintenance status, documentation quality, or community adoption is available
  • Could refer to a personal project, a boilerplate, a rendering engine, or a niche tool - without more context, its quality cannot be assessed
  • Names like this are sometimes used for student projects, abandoned repos, or experimental tools that lack production readiness

Recommended for

  • Not recommended without further verification
  • Developers should search GitHub directly, check star count, last commit date, open issues, and documentation before adopting
  • Best suited for evaluation on a case-by-case basis rather than a blanket recommendation
  • If you have a specific repository URL, sharing it would allow for a more accurate assessment

Questions & Answers

As answered by people managing HourSlip and React Engine.

How would you describe the primary audience of your product?

HourSlip's answer

India's independent services professionals — developers, designers, consultants, writers, marketers, architects, creatives — who invoice clients directly and manage their own compliance.

The defining trait is activity, not size or job title: you raise invoices, someone deducts TDS before paying you, and nobody else is filing your GST or working out your advance tax. It applies whether you bill hourly, fixed-fee, on retainer or by milestone, and whether your clients are Indian, foreign or both. GST registration is not a prerequisite — unregistered users get Bill of Supply and an alert as they approach the ₹20 lakh threshold, because TDS and advance-tax pain start at the very first invoice, long before registration does.

Who it is not for, deliberately: goods traders, retailers and manufacturers, who need inventory, HSN and COGS that HourSlip does not and will not have. Accounting firms are also not the user — a CA can be given read-only access to a client's books, but the account always belongs to the professional.

What makes your product unique?

HourSlip's answer

It is built for one specific person: the Indian independent services professional who invoices clients directly and handles their own compliance.

Most Indian billing software is really built for shopkeepers — inventory, HSN codes, stock, goods billing. Most freelancer software is built for Americans. Neither handles the things that actually consume an Indian professional's time: GST with the correct CGST/SGST or IGST split, the TDS a client silently deducted before paying, advance tax before 234B/C interest starts, and 44ADA presumptive taxation where you qualify.

HourSlip closes the whole money loop on one dataset. Raise a GST-compliant invoice, share it as a link the client pays by UPI or card, log the TDS they deducted across 10 sections, reconcile it against Form 26AS, and see the resulting advance-tax position — without re-entering anything or reconciling three tools in March.

What it deliberately does not do is as important: no inventory, no HSN, no stock, no goods billing. Services only.

Why should a person choose your product over its competitors?

HourSlip's answer

Because the alternatives each solve one fragment of the problem, and the seams between them are where the money leaks.

Zoho Invoice and Refrens raise a clean GST invoice, but neither tells you what tax you owe or tracks the TDS your client deducted. ClearTax and Quicko handle the return at filing time, but they do not run your invoicing or chase your receivables through the year. Vyapar and Tally are built around stock, purchase and goods — a services business has none of that, so most of the product is dead weight. FreshBooks and Bonsai are excellent and entirely foreign: no GST, no TDS, no 26AS, no 44ADA.

The real incumbent is a spreadsheet plus a CA in March, and that is exactly how people end up paying 234B/C interest on tax they could have scheduled in June.

HourSlip keeps invoicing, TDS, GST returns, expenses and tax planning on one dataset, so the advance-tax figure on your dashboard is derived from the same invoices you actually raised. Nothing is re-keyed, and nothing disagrees with anything else.

The honest counter-case: if you sell goods, need inventory or HSN, or want a full double-entry ledger, choose Vyapar, Tally or Zoho Books instead. HourSlip is deliberately not that.

What's the story behind your product?

HourSlip's answer

HourSlip is built by a solo founder in India.

The problem that started it is one every independent professional here recognises. You are squeezed between software built for shopkeepers — Vyapar, Tally, everything organised around stock and purchase — and software built for Americans, like FreshBooks and Bonsai, which have never heard of GST or TDS. Nothing in between handled GST, TDS, advance tax and 44ADA together for a one-person services business. So the work fell into a spreadsheet, and the spreadsheet turned into a panic every March.

The specific thing that stung was TDS. A client deducts 10% before paying, you forget which invoice it came from, and by the time you sit down with Form 26AS a year later you cannot reconcile it. That money is yours, and people routinely lose track of it.

So the product was built the other way round from most invoicing tools: start from what you actually owe and what you are actually owed, and let the invoice be an input to that rather than the end of the story.

The name is a leftover from the timer it began as. The product moved on to the money side long ago, and time tracking is now entirely optional — you can run the whole thing without ever starting a timer. The name stayed because changing it seemed less useful than shipping.
