You have one P&L, but you need channel-specific P&Ls. You can’t see which channels are profitable because costs are mixed together. This blindness prevents you from understanding true channel performance.
Channel-by-channel P&L solves this by creating separate profit and loss statements for each channel. It reveals true channel profitability, which helps you make informed channel decisions. This analysis is essential for channel optimization.
This guide provides a tutorial on constructing mini P&Ls for each sales channel, helping you build channel-specific profit and loss statements that reveal true channel profitability.
We’ll explore why channel P&Ls matter, building revenue sections, tracking costs, calculating profitability, and interpreting results. By the end, you’ll understand how to build and use channel P&Ls.
Key Takeaways
- Build separate P&Ls—create individual profit and loss statements for each channel
- Track revenue separately—record sales from each channel independently
- Allocate costs accurately—assign all costs to appropriate channels
- Calculate channel profit—determine net profit for each channel
- Compare channels—use P&Ls to compare channel profitability

Why Channel P&Ls Matter
Single P&L statements hide channel performance. When you can’t see channel-specific profitability, you can’t optimize channel mix. This blindness prevents profitable growth.
Channel P&Ls matter because they reveal true performance. When you build separate P&Ls, you see which channels are profitable. This visibility enables channel optimization.
The reality: Most businesses don’t build channel P&Ls, which means they can’t see channel-specific profitability. Channel-by-channel P&Ls reveal true performance, enabling informed decisions.
Building Revenue Sections
Revenue sections track sales by channel. When you build revenue sections separately, you can compare channel sales.
Channel Revenue Tracking
Record revenue by channel:
- Track sales from each channel

FAQs - Frequently Asked Questions About Channel-by-Channel P&L: How to Build It and What It Reveals
Why do businesses need separate P&L statements for each sales channel?
A single P&L hides which channels are profitable and which are losing money, because costs from all channels are mixed together making it impossible to see true channel performance.
Learn More...
When all channels are combined in one P&L statement, a highly profitable channel can mask the losses from an unprofitable one. You might think your business is doing well overall while actually subsidizing a channel that's draining resources.
Channel-by-channel P&Ls separate revenue and costs for each channel, revealing true profitability at the channel level. This visibility enables you to make informed decisions about where to invest more, what to fix, and what to cut.
Most businesses don't build channel P&Ls, which means they're making resource allocation decisions based on incomplete information. Building separate P&Ls is the foundation for channel optimization—you can't improve what you can't measure.
How do you allocate shared overhead costs to individual sales channels?
Allocate overhead proportionally based on a fair metric like revenue share, order volume, or time spent, ensuring all costs are included for accurate profitability calculations.
Learn More...
Direct costs are straightforward—marketing spend for a specific channel, marketplace fees, or channel-specific shipping costs go directly to that channel's P&L. The challenge is shared overhead like office rent, management salaries, and general software subscriptions.
The most common allocation methods are revenue-based (allocate proportionally to each channel's revenue share), volume-based (based on order or transaction volume), or time-based (based on estimated time spent supporting each channel).
No allocation method is perfect, but any consistent method is better than ignoring overhead. The key is using the same method consistently over time so you can compare trends. Document your allocation methodology and revisit it periodically to ensure it still reflects reality.
What are the key profitability metrics to calculate in a channel P&L?
Calculate gross profit (revenue minus COGS), operating profit (gross profit minus operating expenses), net profit (all costs subtracted), and profit margin percentages for each channel.
Learn More...
Gross profit per channel is calculated by subtracting cost of goods sold from channel revenue. This shows basic product profitability and reveals whether you're making money on the products themselves before any operational costs.
Operating profit subtracts channel-specific operating expenses from gross profit—marketing costs, platform fees, fulfillment costs, and allocated overhead. This shows whether the channel is profitable after running costs.
Net profit subtracts all remaining costs for a complete picture of channel profitability. Profit margin percentages (net profit ÷ revenue) enable comparison across channels of different sizes—a smaller channel with higher margins may be more valuable to grow than a larger channel with thin margins.
How should you track and adjust for returns and discounts in channel revenue?
Track returns and discounts by channel separately, then subtract them from gross revenue to get accurate net revenue that reflects real money received from each channel.
Learn More...
Returns and discounts can vary dramatically between channels. An online marketplace might have a 15% return rate while your direct website has 5%. If you don't track these by channel, you overstate the profitability of high-return channels.
Build return and discount tracking into your revenue section for each channel. Record gross sales, subtract returns, subtract discounts and promotions, and arrive at net revenue. This net revenue is the true starting point for your profitability calculation.
Track these adjustments over time to spot trends. If returns are increasing on a specific channel, it might indicate product-market mismatch, quality issues, or customer expectation problems specific to that channel. This early warning system helps you address issues before they erode profitability.
How often should channel P&Ls be updated and what decisions should they drive?
Build channel P&Ls monthly and use them to decide which channels to grow, which to fix, and which to exit.
Learn More...
Monthly P&Ls provide the right cadence—frequent enough to spot trends and react quickly, but not so frequent that normal variation causes overreaction. Compare each month to the previous month and to the same month last year to account for seasonality.
Use P&L data to make three types of decisions: which channels to grow (positive and improving profitability), which to fix (negative but improvable profitability with clear path to profit), and which to exit (persistently negative profitability with no realistic fix).
Beyond individual channel decisions, P&Ls reveal your optimal channel mix. You might discover that 80% of your profit comes from one channel while you spread budget across five. This data drives strategic resource reallocation toward your most profitable channels.
What is the difference between direct channel costs and allocated costs in a channel P&L?
Direct costs are expenses clearly tied to a specific channel like platform fees or channel-specific marketing, while allocated costs are shared expenses distributed across channels using a proportional method.
Learn More...
Direct channel costs include anything spent specifically for that channel: marketplace commissions (e.g., Amazon's 15% referral fee), channel-specific advertising spend (Google Ads for your website, promoted listings on marketplaces), channel-specific fulfillment costs, and platform subscription fees.
Allocated costs are shared expenses that support multiple channels: office rent, management and administrative salaries, general software subscriptions, insurance, and accounting fees. These must be distributed across channels using a consistent allocation method.
When building your channel P&L, clearly distinguish between direct and allocated costs. This matters because direct costs are actionable—you can reduce platform fees by negotiating or shifting channels—while allocated costs require different strategies to optimize. The split also shows which channels have inherently higher cost structures.
