Growth that shows up
in the bank account.
Plenty of D2C brands grow revenue every quarter while making less money every quarter. Discounts creep up, shipping subsidies expand, returns eat margin, and ad costs rise, until the growth is actually funded by the founder's equity, not the customers.

Profitability is the pillar that keeps the other five honest. A37 manages pricing, promotions, and unit economics so that revenue growth compounds into profit growth.
Unit economics: the numbers under the numbers.
Profitability starts with knowing exactly what one order earns after everything it costs. Most brands can quote their revenue; far fewer can quote their contribution margin per order, and that gap is where losses hide.
- Contribution margin per order: price minus COGS, fees, shipping, packaging, payment costs, and allocated returns
- True CAC by channel: including creative, tools, and management, not just media spend
- Return-adjusted revenue: a sale that comes back is a cost, not a sale
- SKU-level P&L: most catalogues make 80% of their profit on 20% of SKUs, know which
Pricing and promotions with discipline.
Discounting is the most abused growth lever in eCommerce because it always works, on revenue. A permanent 20%-off habit trains customers to never pay full price and silently resets your brand's value perception.
Discipline doesn't mean never discounting; it means discounting deliberately: planned promotion calendars with margin floors, bundles that raise AOV instead of blanket price cuts, and tiered offers that protect hero-SKU margins while clearing slow movers.
- Promotion calendar with per-event margin floors and post-mortems
- Bundling and AOV architecture: free-shipping thresholds, gift-with-purchase, multi-packs
- Price testing on marketplaces versus your own store, positioning each channel deliberately
- Discount audit: which codes actually create incremental orders versus subsidising existing ones
Profitability is a system, not a spreadsheet.
The other five pillars all feed this one: acquisition sets CAC, conversion sets how much traffic monetises, retention sets LTV, marketplaces set fee loads, operations set fulfilment and return costs. Manage them separately and profit is an accident; manage them as one engine and it's a design outcome.
That is A37's operating model: one team, one dashboard, one P&L view across every pillar, reviewed monthly with next-month priorities attached to the numbers.
Frequently asked questions.
- What is contribution margin and why does it beat gross margin?
- Gross margin subtracts only COGS. Contribution margin also subtracts everything it takes to deliver an order, shipping, payment fees, packaging, marketplace commissions, and allocated returns. It's the number that tells you whether the next marginal order is worth acquiring, which is why we manage ad spend against it.
- My revenue is growing but profit isn't. Where do I look first?
- In order: discount depth and frequency (has 'sale' become the default price?), fully-loaded CAC by channel, return rates by SKU and pincode, and shipping subsidy per order. One of these four explains the gap for almost every brand we audit.
- Should I raise prices?
- More brands are underpriced than overpriced, especially post-scaling, when costs crept up and prices didn't. Test increases on hero SKUs where you have review depth and low comparison pressure. A 10% price increase typically outperforms a 10% CAC reduction because it hits the P&L with no extra cost.
- How often should I review unit economics?
- Monthly at minimum, and always before scaling spend. Ad platforms, courier rates, marketplace fees, and return patterns all drift. A monthly P&L-per-order review is how you catch a 3-point margin leak before it compounds across a quarter of orders.
