HelloBooks vs Sleek Bill: A full ledger with GST filed for you vs a billing app that syncs to a GSP

Sleek Bill is a lightweight Indian invoicing product from V K Control System. It is billing-first: there is no chart of accounts, no journal entry and no balance sheet anywhere in its plan features, and its own knowledge base has 66 articles on billing and none on ledgers. The Pro tier adds an "Accounting Module" that produces P&L, cash book and petty cash — useful, but not a general ledger.

Credit where it is due: Sleek Bill is the only product in our India set that names its GSP. It syncs GST data to LegalRaasta, where you complete the filing. It also has a genuine free tier — 10 documents a month with branding — and e-invoicing and e-way bills at the Pro tier using your own IRP credentials.

HelloBooks is the ledger, with GSTR-1, 3B and 9 filed through Fynamics (a GSTN-authorized GSP), e-invoicing, e-way bills, inventory and AI included from ₹499/month. One thing to correct: the widely repeated "Sleek Bill has no mobile app" complaint is out of date — the app shipped and was updated in June 2026.

When to choose HelloBooks

  • Your accountant needs a balance sheet and trial balance — Sleek Bill does not produce either at any tier.
  • You want GSTR-1, 3B and 9 filed for you through a GSP rather than synced to one for you to finish.
  • You need e-invoicing and e-way bills without stepping up to the ₹7,080/year Pro tier.
  • You carry stock and need valuation methods, GRN and multi-warehouse rather than a simple item list.
  • You want an API or integrations — Sleek Bill has neither, and reviewers say so.
  • You want AI doing the categorisation and reconciliation, which Sleek Bill does not offer at any price.

When to choose Sleek Bill

  • Raising clean GST invoices is genuinely the whole job and your CA keeps the books elsewhere.
  • You want the simplest possible product — Sleek Bill wins "ease of use" awards for a reason, and holds 4.8 on Capterra.
  • You value a vendor that names its GSP openly; most Indian products do not.
  • You bill internationally and want multi-currency invoicing across many countries from a light tool.
  • Your volume genuinely fits the free tier at 10 documents a month and you do not mind the branding.
  • You want thermal receipt printing at 2 and 3 inch for a counter operation.

Frequently asked questions

Does Sleek Bill have a mobile app?

Yes — and this is the single most out-of-date claim in comparison content about Sleek Bill. The "Sleek Bill Billing Software" app is on Google Play from V K Control System Private Limited, rated 5.0 from 114 reviews and updated 4 June 2026, with GST invoices and auto CGST/SGST/IGST, quotations, purchase orders, payment tracking, multi-currency and WhatsApp/email PDF sharing. G2 still lists "no native mobile app" as its primary criticism and Capterra reviews mentioning the absence date from before the app shipped. We are flagging it because we would want the same correction made about us.

How much does Sleek Bill cost in 2026?

From sleekbill.in/pricing on 28 July 2026: Free Forever at ₹0 capped at 10 documents a month with branding; Premium Business from ₹2,360 a year; Multi User from ₹3,540 a year for up to five users; Sleek Bill Pro from ₹7,080 a year for up to ten users. Techjockey matches the vendor. Ignore SoftwareSuggest for Sleek Bill — it lists ₹28 and ₹44 per year figures that are currency-conversion artefacts and names the wrong vendor entirely.

Is Sleek Bill a proper accounting system?

No, and the evidence is in its own knowledge base rather than in marketing. The article categories are Getting Started (8), GST Explained (4), Partners (1), Billing & Invoicing (66), Inventory (6) and Reports & Data (26) — with no accounting or ledger category at all. The Pro-tier "Accounting Module" produces P&L, cash book, petty cash and client and vendor statements. There is no chart of accounts, journal entry, trial balance or balance sheet. Reviewers on Capterra frequently request balance sheet reporting and Techjockey notes it lacks expense tracking and balance sheets versus alternatives.

Does Sleek Bill file my GST returns?

It prepares and syncs. The GST filing page describes clicking "Sync Data to LegalRaasta" — its named GSP partner — to push GST report details toward the government website faster, with the free-plan alternative being to export the GST report by email and upload it yourself. So Sleek Bill does not file for you; it gets your data to a GSP where you complete the process. HelloBooks files GSTR-1, 3B and 9 through Fynamics, a GSTN-authorized GSP, from inside the product.

Which is better for e-invoicing?

HelloBooks includes IRN and QR generation through the IRP from Pro at ₹499/month. Sleek Bill does e-invoicing and e-way bill generation at the Pro tier from ₹7,080 a year, and takes a different technical route — you enter your own API user ID and password obtained from the e-invoice portal into Sleek Bill preferences, then generate with one click. That works, but it means you manage the portal credentials yourself.

What does HelloBooks cost in India?

Free forever with 2,500 AI credits a month, up to two users, and no turnover cap. Pro is ₹499/month or ₹4,999/year against a list price of ₹999 — unlimited users, multi-entity, GST filing and e-invoicing, Tally sync, API access, inventory, three-way matching and multi-currency. Business is ₹1,999/month or ₹19,999/year.

Does Sleek Bill have AI?

No. We found no AI feature, page or announcement on sleekbill.in or in any 2026 directory listing. This is the clearest AI gap of the Indian products we compared. HelloBooks includes AI auto-categorization at 95%+ accuracy, OCR with line extraction, Munimji (a conversational assistant with 60+ tools), WhatsApp bookkeeping with voice notes, AI payables, AI calling for overdue receivables and a CFO agent, all from one credit wallet starting on the free plan.

Can Sleek Bill integrate with anything?

Very little, and its own reviewers say so. There is no public API — a SoftwareSuggest reviewer says the lack of API integration limits the software's adaptability, and Capterra cons include lack of third-party integration. Documented connections are the LegalRaasta GSP sync, the NIC e-invoice and e-way bill portals via your own credentials, email, and UPI QR codes. HelloBooks ships Plaid, Stripe, Razorpay, PayPal, PineLabs, a Tally 6.2 connector, API access from Pro and a public read-only MCP server.

Can I move Sleek Bill data into Tally?

Only manually. There is no native Tally connector; the documented route is exporting from Sleek Bill and importing masters such as customers and items into Tally through Gateway of Tally. HelloBooks has a Tally 6.2 connector that imports keeping every voucher number and then keeps pushing to Tally, so your CA can stay on Tally while your day-to-day books move to the cloud.

What do Sleek Bill users complain about?

Consistently: no third-party integrations and no API; no balance sheet reporting; limited invoice template customisation; and, in older reviews, missing e-way bill and WhatsApp support — both of which now exist, so treat those as dated. A SoftwareSuggest reviewer reports being charged for support and upgrades despite an initial lifetime-free promise. On the positive side, its ratings are genuinely strong: 4.8 on Capterra from 43 reviews with customer service at 4.9, plus Software Advice and Capterra ease-of-use badges for 2026.

Can I migrate from Sleek Bill to HelloBooks?

Yes. Import and export are listed from the Premium Business tier, and the knowledge base documents a backup and restore workflow. Export your customers, items, invoices and purchase records to CSV and import them into HelloBooks, where the chart-of-accounts import uses AI to read your existing structure, retain account numbers and map intelligently. The flow at /migrate includes a dry-run preview and one-click rollback so you can test before committing.

Which has the better free plan?

They solve different problems. Sleek Bill Free gives you 10 documents a month with Sleek Bill branding on them and no GST reports. HelloBooks Free gives unlimited invoices, bills, quotes and purchase orders with no branding, AP and AR aging, P&L, balance sheet and cash flow, the full mobile app, two users and 2,500 AI credits a month — and in India it is uncapped by turnover. If you are past a handful of invoices a month, the difference is significant.

Is HelloBooks secure?

HelloBooks is SOC 2 Type II certified, with the report available under NDA through the Trust Center; ISO 27001 is on the compliance roadmap and we do not claim it as certified. Data is AES-256 encrypted at rest and TLS 1.2+ in transit, MFA is available, hosting is AWS with 99.9% uptime and daily encrypted backups, and bank connections are read-only. India DPDP is covered.

Migrating from Sleek Bill?

HelloBooks supports CSV import for chart of accounts, customers, vendors, items, invoices, and bills. For QuickBooks Online, we offer a built-in two-way sync. For other platforms, our migration team can assist with a structured cutover.
