What BillDiary is

Four outcomes. One platform.

Skip the “billing app + inventory app + reports in Excel” stack. BillDiary is built so selling, stock, money, and visibility stay in one governed workspace.

Peak-hour POS & GST-ready billing

Contacts, dues & payments in one ledger

Customers and suppliers, groups, ledgers, and payment history beside billing—not scattered across sheets.

Scale without switching tools

Trusted reporting, optional modules, and integration-ready APIs when you add locations, service, or depth.

FAQ

Answers visitors look for before pricing, sign-in, or registration.

Straight questions about scope, GST, scale, and next steps—so the homepage feels complete without hunting through brochures.

What is BillDiary in one sentence?

BillDiary is an all-in-one workspace for POS billing, inventory, customers and suppliers, money controls, reports, and optional modules—so teams stop stitching spreadsheets and separate apps together.

Can we start with counter POS and add inventory when we are ready?

Yes. Many teams begin with fast billing and clean invoices, then turn on deeper catalog, stock movement, and barcode workflows when the business is ready—without changing products or re-entering everything from scratch.

Does BillDiary support GST-ready invoices and tax reporting for Indian businesses?

The platform is built around structured tax lines, invoice schemes, layouts, and reporting families that align with how Indian retail and distribution teams reconcile GST—not a generic “export to Excel and hope” workflow.

Can multiple branches, registers, or staff share one account safely?

BillDiary supports multi-location setups, register-aware sessions, and role-oriented access patterns so owners can scale beyond a single counter while keeping activity inside one governed workspace.

Is there an API and integrations path for ecommerce or ERP connectors?

Yes. There are integration APIs, developer documentation, and an integrations console for inbound and outbound flows—plus patterns for restaurant, essentials, and hosted-business scenarios when you outgrow a single shop footprint.
