A spreadsheet tracks numbers. DomFlat tracks the whole tenancy — reminders, the signed lease, repair deductions, and warranty alerts — for free on up to 3 properties.
Quick answer
DomFlat is free for the same 1-3 properties a spreadsheet covers, and it does things a spreadsheet structurally can't: send a rent reminder, store a signed lease, auto-deduct an approved repair claim, or alert you before a warranty expires.

For tracking who paid what, a spreadsheet works fine at first. Where it breaks down is reminders (a spreadsheet won't message a tenant who's late), documentation (a spreadsheet isn't a signed lease or a deposit-dispute paper trail), and access (only one person can safely edit it at a time). DomFlat is free for the same 1-3 properties a spreadsheet covers, so there's no cost trade-off to try it.
You add properties, tenants, and lease terms through the app, and DomFlat generates the payment schedule from there — there isn't a bulk spreadsheet importer today. For 1-3 properties this is a five-minute setup.
A spreadsheet can calculate, but it can't act: it won't email a tenant, won't store a receipt behind a secure link, won't notify you before a warranty lapses, and won't generate a signed PDF lease. DomFlat automates the parts of property management that happen outside the numbers.
