Run your merch table like a business, not a shoebox full of receipts

If Backstage Books is your road manager for income and expenses, Backstage MerchMaster Pro is your merch table's bookkeeper, inventory clerk, and shrinkage detective — all rolled into one Notion template built specifically for musicians who sell shirts, vinyl, CDs, stickers, and everything else out of the back of the van.

You already know the headache: you ordered 50 shirts, sold 38, comped 2 to the sound guy, lost 1 to a beer spill, and now you're trying to figure out if you actually made money on the night. MerchMaster Pro does that math for you — in real time.

What's inside

📦 Inventory Intake (Purchase Order style)

Log incoming product the way your supplier invoices you — per item, per order. Enter your cost and MerchMaster Pro automatically calculates cost-per-item and rolls it into your total inventory value, so you always know what's sitting in those merch bins.

🧾 Sales Form (Invoice-Style Line Items)

Ring up sales the way you'd write an invoice — line by line. Built-in fields handle:

- Item-level discounts *and* whole-order discounts

- Sales tax percentage (auto-calculated)

- Amount tendered and change due — handy for those cash-only merch table nights

🔄 Returns & Exchanges

Customer service happens — a shirt's too small, a CD's defective. This form handles the exchange or refund while keeping your inventory counts and value accurate behind the scenes.

📉 Shrinkage Tracking

Stolen, damaged, given away, or just plain vanished — shrinkage gets logged separately from sales so you can see the real story of where your product went, not just what got "sold."

📊 Real-Time P&L and COGS

No spreadsheets, no end-of-tour scramble. Your Profit & Loss and Cost of Goods Sold calculate live as you log purchases and sales, so you can check your merch table's actual profitability whenever you want — mid-tour, mid-month, mid-anything.

Inventory that updates itself

Every transaction — sale, return, shrinkage — automatically adjusts your live inventory numbers. No manual recounts, no "I think we have 12 left?" guesswork.

Who it's for

Built for working musicians and bands who sell merch regularly enough that "I'll just remember" stopped working a long time ago. Whether you're running one box of shirts or a full multi-SKU merch operation across tour stops, MerchMaster Pro scales with your table.

One-time purchase. No subscription. No monthly fee eating into your merch profits.

Like every Gig Flow Solutions product, you buy it once and it's yours — set it up in your Notion workspace and run it your way, forever.
