Rent Bills, GST and Outstandings β€”
For Every Unit, Every Month.

dsRentMaster is billing and lease software for people who rent out many units β€” shops, offices, godowns, flats β€” sometimes across several owners. It produces monthly GST bills for rent plus electricity and maintenance, applies rent increases on schedule, records receipts and shows exactly who owes what. It runs on your own server, so your data stays with you.

Still Running Rent on Excel and a Diary?

The usual leaks once you have more than a handful of tenants.

Missed rent increases

The agreement says 5% every year, but nobody remembers to apply it β€” and the loss compounds year after year.

GST done by hand

Different owners, different GSTINs, tenants in other states β€” each bill needs the right GSTIN and the right tax.

"How much is pending?"

Part payments, electricity and maintenance on top of rent β€” the true outstanding takes an afternoon to work out.

Set Up the Lease Once. Bill Every Month in Minutes.

You stay in control: nothing is billed until you have reviewed the month's dues.
