What this is

An invoice is a by-product. The ledger is the product.

Most billing software prints a document and files a copy. When the year ends, somebody rebuilds the accounts from those copies. This works the other way round: every transaction is a balanced voucher first, and the invoice is what one kind of voucher happens to look like on paper.

Billing software

  • Documents, with totals stored on them
  • Reports assembled at year end
  • Stock and books reconciled by hand
  • “Export it to your accountant”

Falcon

  • Balanced vouchers against a chart of accounts
  • Statements derived on every request
  • Stock movement and ledger entry in one transaction
  • Your accountant works in the same books

Coming from somewhere else

Your existing books come with you

In the desktop application, point it at the Tally running on your own network and it reads the masters and the day book across. Anywhere, ledgers, customers, items and opening balances come in from CSV files. Either way everything is staged and checked before a single entry is posted.

How it is built

The guarantees underneath

These are not features you switch on. They are properties of the system — which is what makes them the hardest part to retrofit, and the easiest part to fake.

Every query scoped to your business

Every read and write is limited to your organisation and company, and an id from another business is answered as not found. Row-level security in the database adds a second lock on writes and on posting today; extending it to every read is in progress.

Built for more than one company

Companies, financial years, numbering series and group consolidation, which detects trading between group companies and shows it for elimination. Group reporting is not a separate product here.

Nothing stored twice

Every total is derived from postings. There is no cached balance to go stale, no nightly rebuild, and no support ticket that begins “the report disagrees with the ledger”.

Nothing here is connected to a government system. No filing credential is stored, no portal is scraped, and no return is submitted on your behalf. Identifiers produced by the e-invoicing screen are marked SANDBOX and must not be issued to customers.

Straight answers

The questions everybody asks

Is this an invoice generator?
Invoicing is one of nineteen voucher types. Underneath it is a double-entry ledger with multi-company books, GST, banking, inventory, payroll, fixed assets, period close and consolidation — the invoice is simply the document a sales voucher happens to produce.
Does it file my GST returns?
No, and it holds no credential that would let it. It prepares working papers you or your accountant can check and file. The e-invoicing screen runs against a mock provider, says so on screen, and marks every identifier it produces as SANDBOX.
How is one business kept separate from another?
Every query is scoped to your organisation and company, and an id that belongs to another business is answered as if it did not exist. 95 row-level security policies in PostgreSQL add a second lock on writes and on posting; extending that lock to every read is in progress.
Where are my books kept?
Falcon online stores them on servers in the United States, not in India. The Windows desktop application keeps them on your own computer instead; its installer is not published yet.
What happens when the books do not agree?
26 integrity rules run over the whole ledger and return the rows that failed — a trial balance that does not tie, control accounts that disagree with their detail, negative stock, gaps in a numbering series. You get the entries to look at, not a warning light.
