  • Request an IRN or complete e-invoice/e-way bill portal actions.

LOCAL DATA, PRACTICAL BACKUPS

Your billing records stay on your computer

Desktop stores your working billing database locally, rather than automatically storing it in Sleek Bill Online. The exact database folder depends on the installation; use the built-in backup tool to create a portable copy.

Keep another copy on a separate drive or an approved backup location. A backup stored only on the same computer can be lost with that computer.

Set up scheduled email backups →

Email backups require an internet connection and email configuration. Manual backup/restore availability depends on your licence.

01

Create a backup

Open Tools → Backup Data, choose Backup, select a safe location and save the file.

02

Restore your records

Open Tools → Restore Data, select your saved Sleek Bill backup file and choose Restore.

DESKTOP QUESTIONS

Install with a little more clarity

Can I transfer data to another computer?

Yes, the backup and restore tools provide a way to transfer a Desktop database. Back up the old computer, install a compatible version on the new one and restore the file. Confirm licence transfer and cross-platform compatibility with support.

Does e-invoicing need internet?

Yes. IRN generation and government portal submissions require an internet connection. Local invoice creation or an export file is not a registered e-invoice. Confirm the Desktop workflow and eligible plan with support.

Which printers are supported?

Desktop provides A4/A5 invoice layouts and POS formats for 58 mm (2-inch) and 80 mm (3-inch) paper. Printer-model compatibility is not a verified universal guarantee; use a suitable OS driver and test a sample before purchase.

Is Desktop the same as Sleek Bill Online?

No. Desktop runs on your computer and keeps the working database locally. Online runs in a browser and needs internet. List imports/exports can help with a move; automatic Desktop-to-Online sync is not available.

Can I back up without internet?

A local backup uses Tools → Backup Data and saves a file to your chosen location. Scheduled email backups need internet and configured email settings. Check backup entitlement on your licence.

What happens after the 15-day trial?

Choose a paid Desktop licence to keep its included Premium features, or use the Free plan with 10 documents per month, branding and limited advanced features.
