Two of these pages are written against a gap rather than a feature. There is no direct Marg importer, and the Tally import brings vouchers across as balanced journals rather than as itemised invoices. Both pages say so in their first paragraph.
Migrations fail on expectations rather than on technology.
Busy migrations are usually easier than people expect, because Busy exports cleanly and its concepts map almost one to one.
There is no direct Marg importer in tBiz, and rather than let you discover that during onboarding, here is the route that does exist: CSV.
If your books are already in spreadsheets, you have the easiest migration there is — your data is structured and you do not have to export it from anything.
Most Indian businesses already chase payment on WhatsApp; they just do it by taking a screenshot. tBiz sends the document itself, from your business number, through the Meta Business API — so the message is logged against the party and you know whether it arrived.
Bank reconciliation is the check that everything else is true.
The gap between "the customer has paid" and "the receipt is against the right invoice" is where most receivables confusion lives.
A barcode scanner is not a productivity upgrade; it is the difference between a stock count that finishes and one that gets abandoned at four in the afternoon. tBiz treats the scanner as what it is — a keyboard that types faster and never misreads.
Start free, import your masters, and reconcile against your old trial balance.
