What this actually means in practice
A business usually outgrows standalone invoicing at a predictable moment: the accountant asks for a Balance Sheet and there isn't one, or a GSTR-2B mismatch needs tracing back to a purchase that was never recorded. What is needed then is not prettier invoices but the layer underneath — purchases, payments, a chart of accounts, stock valuation and returns that reconcile — while keeping the document quality and the speed that made invoicing pleasant in the first place.
The good news is that invoicing tools hold less to move. Customers, items, rates, HSN codes and your numbering series import straight from a spreadsheet, and you set opening balances for anyone who still owes you. Past invoices themselves stay put — there is no automated import from Sleek Bill or any other billing tool. Because invoice numbering matters to auditors, most businesses restart the series at a financial-year or quarter boundary and archive the old PDFs.
LekhaPro keeps the invoice pleasant — ten-plus layouts including 80mm thermal, credit and debit notes, one-tap WhatsApp or email share — and puts a posted double-entry ledger behind it, with inventory, COGS, banking and GSTR-1/3B derived from the same entries. Sleek Bill is a straightforward invoicing product and many businesses are perfectly served by one; the case for changing only holds if you actually need the books, not just the documents.
| What to check before switching | How LekhaPro answers it |
|---|---|
| Do invoices post to a real double-entry ledger, or only print? | Every invoice posts a balanced journal; Trial Balance, P&L and GSTR-1 all derive from the same books. |
| Can I record purchases and expenses, not just sales? | Yes — purchase bills, expenses, TDS/TCS and vendor payments post to the same ledger as your sales. |
| Will my invoice numbering series carry on? | You set prefix, format and starting number per series, so numbering continues sensibly after cut-over. |
| Do the invoice designs hold up? | Ten-plus GST layouts including 80mm thermal, carrying your logo, terms and bank details. |
| Is bank reconciliation possible? | Yes — import any Indian bank statement; entries are auto-mapped, de-duplicated and categorised for matching. |
| What happens to my old invoices? | They stay in the old tool as PDFs. Only masters and outstanding balances come across. |
| Does moving up cost significantly more? | The full offline core, ledger included, is ₹249 a month; ₹449 adds multi-seat and automation. |

Frequently asked
Is LekhaPro a good Sleek Bill alternative?
Yes if you want invoicing plus full offline accounting, GST returns and inventory in one app rather than billing alone.
Can I share invoices on WhatsApp?
Yes — one-tap share via a WhatsApp/email link with a prefilled message.
Is it offline?
Yes — billing, books and GST run offline.
Will my invoice numbers clash after switching?
Not if you set the series first. Define the prefix, format and next number to continue from wherever the old tool stopped, and LekhaPro carries on the sequence. If you are switching at a financial-year boundary, most businesses restart at one with a new prefix instead — either is acceptable, provided the series stays unbroken within the year.
I only need invoices today. Is a full accounting system overkill?
It might be, and that is a fair conclusion. The reason businesses move anyway is that the ledger becomes unavoidable at audit, at a GST notice, or when stock and margin stop adding up. If none of those apply yet, stay where you are; if one already has, adding books later means re-entering a year you could have captured properly from the start.
What exactly is included in Alternative · billing?
10+ GST invoice layouts, credit & debit notes, double-entry books & GST returns, inventory & COGS, one-tap WhatsApp / email share and deterministic AI insights, and 1 more. Every item on that list is a working screen you can open in the trial rather than a capability described in the abstract.
How is alternative · billing handled differently here?
It rests on beautiful GST invoices, real accounting behind and offline & AI. The distinction that matters is that these are structural rather than cosmetic — the behaviour is built into how records are posted, not layered on as a report you have to remember to run.
How does Alternative · billing affect my GST?
It feeds it directly rather than sitting alongside it. CGST/SGST and IGST are split from HSN or SAC and place of supply as each document is raised, so whatever alternative · billing produces is already correct when GSTR-1, 3B and 2B reconciliation are drawn off the same books. The return matches the accounts because it was never a separate exercise.
Does Alternative · billing cost extra?
No. Alternative · billing is part of the accounting core rather than a paid add-on, so real accounting behind is there on the entry tier exactly as it is on the highest one. What the tiers change is reach and depth — devices, multi-branch and multi-warehouse reporting, and whether the conversational AI copilots are switched on.
Can I try Alternative · billing before committing?
Yes — 14 days, no card. Test alternative · billing against your own masters and your own transactions rather than sample data: the questions worth answering here are about your business's edge cases, and a demo dataset is built not to have any.
