nouz vs PnL Ledger: two "daily P&L" apps that share four words and zero use cases.

The short version: nouz and PnL Ledger are not competitors, alternatives, or substitutes. PnL Ledger is a trading journal — a P&L calendar for day traders logging their wins and losses trade by trade. nouz is a daily operating P&L for small shops — a café, boutique, or salon owner checking whether today paid for itself. They collide only in the search box, because both answer to the phrase "daily P&L app." If you landed here trying to figure out which one you want, the answer is almost certainly obvious within a paragraph — so let's make it obvious.

TL;DR

Why these two get compared at all

This is a strange comparison to write, because there is nothing to compare on the merits. The two tools do not do the same job, do not target the same person, and would never appear on the same shortlist for anyone who understood what each one was. The comparison exists only because "daily P&L app" is an ambiguous phrase that serves two completely disjoint audiences — and both of them type the same words into the same search box.

So a shop owner searching for a way to track store profit can land on a trading journal full of candlestick vocabulary — win rate, R-multiples, max drawdown — and wonder what any of it has to do with their café. This post exists to sort that out cleanly, with respect to both tools, so nobody wastes a signup on the wrong one.

What PnL Ledger actually is

PnL Ledger is a trading journal built around a P&L calendar. It is aimed squarely at individual retail day traders — people trading stocks, futures, or forex from a personal account — who want to log their trading results and understand their own performance over time. It ships as an iOS and Android app with a web version, and it is priced like a hobbyist tool: roughly $4.99 per month, with cheaper annual and lifetime options.

What it does well. The core is a calendar view where each day shows your net trading profit or loss, colour-coded, so you can see streaks and patterns at a glance. On top of that it computes the metrics traders actually care about: win rate (the share of trades that were profitable), profit factor (gross wins divided by gross losses), expectancy and R-multiples (average return per unit of risk), and drawdown (how far the account fell from its peak). These are genuinely useful numbers for a trader trying to understand whether their edge is real and whether their risk management holds up. The app also publishes trader-education content — plain-English guides to expectancy, profit factor versus win rate, and break-even win rates by risk-reward ratio — which is a sensible content strategy for its audience.

Who it is for. Anyone who places trades and wants a disciplined record of them — that is the whole audience, and PnL Ledger serves it directly. None of its vocabulary, metrics, or workflow has anything to do with running a shop: there is no concept of revenue, cost of goods sold, fixed costs, VAT, or card fees, because a day trader does not have any of those. That is not a gap in PnL Ledger; it is simply a different product for a different person.

What nouz actually is

nouz is a daily P&L SaaS built for small brick-and-mortar shops — cafés, boutiques, salons, and small e-commerce stores. Its one job is to answer "did today pay for itself?" before you close up. You enter the day's gross revenue (split cash versus card), product sales or manual receipts, and any variable or one-off costs. The app applies your tax rate, subtracts card fees from card revenue only (never from cash), deducts cost of goods sold from product entries, and allocates a daily slice of your monthly fixed costs — rent, salaries, software, insurance — by dividing the monthly fixed total by 30.4375. The output is a single operating-profit number (EBIT) for today, shown to two decimal places, available the same evening.

The formula, stated plainly: gross revenue minus tax minus card fees gives net revenue; net revenue minus COGS minus variable costs minus the daily fixed slice gives EBIT. That is the entire model, deliberately the kind of thing a non-technical owner can understand at a glance. Setup runs about seven minutes, and there is a live demo seeded with realistic data if you want to see it first.

Where nouz stops. To be equally honest about scope: nouz is not bookkeeping or tax software, it has no POS integration yet, and no CSV export yet. It is English-only and EU-focused today. It is a daily operating tool, not a statutory record — but it was never trying to be, any more than PnL Ledger was trying to track a salon's takings.

The two meanings of "P&L"

The whole confusion lives in one abbreviation carrying two meanings. Once you see the split, the choice between these two tools makes itself.

In trading, a "P&L" is the net result of your positions — a running score of money made or lost on trades. A "daily P&L" is that score for one day: a series of trades, each with an entry price and an exit price, and the difference is the profit or loss. The interesting questions are about consistency and risk — how often you win, how big your winners are versus your losers, how deep your worst run goes.

In a business, a "P&L" is the profit-and-loss statement — revenue and the costs incurred to earn it. A "daily P&L" is that statement compressed to a single trading day: what came in, what it cost to serve, and what was left over after a fair share of the fixed costs. The interesting questions are about margin and break-even. These are not two flavours of the same measurement; they are two different measurements that happen to share a name.

Side-by-side: trading journal vs business daily P&L

The clearest way to see the gap is line by line. The point of this table is not to declare a winner — each tool wins decisively for its own audience — but to show how little the two overlap once you look past the shared name.

Which one were you looking for?

The test takes about ten seconds. Ask yourself what you are trying to track.

• Do you place trades in a brokerage account? Stocks, futures, options, forex — you open positions and close them. Then you want a trading journal, and PnL Ledger is built for exactly that. nouz has nothing for you; it does not know what a trade is.
• Do you run a shop with a till? A café, a boutique, a salon, a small e-commerce store — you take money from customers and pay rent, staff, and suppliers. Then you want a business daily P&L, and that is what nouz does. PnL Ledger has nothing for you; it does not know what rent is.
• Do you do both? Rare, but possible — someone who trades on the side and also owns a shop. In that case you would use both tools, one for each activity, and they would never touch. They are not alternatives; they are separate instruments for separate parts of your life.

If you are the shop owner in that list, here is where to go next. The free daily profit calculator runs the exact EBIT formula in your browser with no signup, and the daily profit-and-loss template gives you the same structure as a spreadsheet if you want to sketch your numbers by hand first. When you are ready to compare purpose-built options, the best daily P&L tracker guide walks through five of them honestly.

And if you are the trader who ended up here by accident: PnL Ledger is a perfectly good tool for what you need, and this post was never trying to talk you out of it. The shared name pulled you to the wrong page — no harm done, and you know which one you want now.

The honest summary

PnL Ledger and nouz are not rivals. One is a trading journal that helps a day trader understand their win rate, profit factor, and drawdown for around $4.99 a month. The other is a daily operating P&L that helps a shop owner see whether today paid for itself, applying tax, card fees, COGS, and a daily slice of fixed costs to land on an EBIT number by close of day. They share four words in their category name and nothing else. The only real decision here is a two-second one: trades or a shop. Pick the tool that matches the thing you actually run, and ignore the coincidence of the name.
