Live product UI — sample data.

  • Four levers, instant answers

    Price, volume, cost and expense changes recompute a projected P&L the moment you move a slider.

  • Built on your real baseline

    Starts from your actual revenue, COGS and expenses — so the “what if” is grounded, not hypothetical.

  • Deterministic & offline

    No LLM, no round-trip — the model runs locally and is fully verifiable.

What this actually means in practice

The simulator does not start from a blank sheet. Its baseline is your own profit statement for the period you choose — net sales after credit notes, cost of goods sold at your chosen valuation, weighted-average or FIFO, falling back to net purchases where stock is not tracked, and booked operating expenses. Those three figures come straight from the same posted registers that produce your P&L, so the starting point on screen ties to the statement you would hand to a CA.

Moving a lever re-derives that statement rather than predicting anything. A price change scales revenue; a volume change scales revenue and COGS together; a cost change scales COGS; an expense change scales operating expenses. Custom variables — fuel as a share of expenses, a flat hiring-freeze saving, interest or tax below the line — are applied on top in a fixed order, each reporting its own rupee impact. The same levers on the same baseline always return the same projected profit and margin.

Businesses reach for it before committing: whether a five per cent discount to win a distributor survives contact with the margin, how much volume must rise to absorb a supplier's price increase, what a rent revision does to the year. A sensitivity sweep varies one lever across a range and returns the response curve. Nothing is posted — it is a read-only projection, and a saved scenario freezes its own baseline so later edits to the books cannot quietly rewrite yesterday's decision.

What’s included

  • Price / volume / cost / expense levers
  • Live projected P&L
  • Δ net profit & margin
  • Built from your real figures
  • Runs offline
  • In every plan

What it does not do

  • · It projects arithmetic, not the market. The engine says what your P&L becomes if a lever moves; whether customers accept the new price is your judgement, not its output.
  • · The baseline inherits your books' completeness. Where stock is untracked, COGS falls back to net purchases and the projection carries that approximation forward.
  • · Read-only by design. No scenario posts a voucher, edits a price list or touches stock — a saved scenario is a snapshot for discussion and approval.
  • · Deterministic what-if modelling is in every plan from ₹249 monthly; the conversational AI that would talk you through a scenario is the ₹2,499 Enterprise tier.

Frequently asked

Does it change my books?

No — it’s a read-only simulation. Nothing is posted; it’s purely for planning.

Is it included in Basic?

Yes — it’s deterministic Tier-A intelligence, in every plan.

Can I model something beyond the four standard levers?

Yes. Alongside price, volume, cost and expense you can add named variables of your own — fuel at a fifth of expenses, a flat rupee saving from deferred hiring, an interest or tax line below operating profit. Each is applied in a defined order and reports its individual rupee impact, so no single effect hides inside the total.

Will a saved scenario change when my books change?

No. Saving freezes both the levers and the resolved profit statement, so a scenario approved last quarter still shows the figures it was approved on. Re-run it against today's books whenever you want the current view — the earlier snapshot stays intact for the record and for comparison.

How is ai · deterministic handled differently here?

It rests on four levers, instant answers, built on your real baseline and deterministic & offline. The distinction that matters is that these are structural rather than cosmetic — the behaviour is built into how records are posted, not layered on as a report you have to remember to run.

Does AI · deterministic work offline?

On the Desktop edition, yes — completely. price / volume / cost / expense levers and live projected P&L run against a local database on your own machine, so the screens behave the same with the network unplugged as with it connected. AI and billing are the only two things that reach out. On the Cloud edition ai · deterministic runs in the browser and needs a connection.

How does AI · deterministic affect my GST?

It feeds it directly rather than sitting alongside it. CGST/SGST and IGST are split from HSN or SAC and place of supply as each document is raised, so whatever ai · deterministic produces is already correct when GSTR-1, 3B and 2B reconciliation are drawn off the same books. The return matches the accounts because it was never a separate exercise.

Does AI · deterministic cost extra?

No. AI · deterministic is part of the accounting core rather than a paid add-on, so built on your real baseline is there on the entry tier exactly as it is on the highest one. What the tiers change is reach and depth — devices, multi-branch and multi-warehouse reporting, and whether the conversational AI copilots are switched on.

Can I try AI · deterministic before committing?

Yes — 14 days, no card. Test ai · deterministic against your own masters and your own transactions rather than sample data: the questions worth answering here are about your business's edge cases, and a demo dataset is built not to have any.

Can I get my ai · deterministic data out again?

Yes. On the Desktop edition everything AI · deterministic records sits in a local database on a disk you choose, with scheduled encrypted backups you control — stopping payment leaves you holding a readable file. On the Cloud edition your data is isolated to your business by row-level security and exportable from the reports it feeds.
