How to forecast runway and months of cash as CPG Founders
Your runway number lives in a spreadsheet that's already wrong. You've got Stripe capturing DTC revenue, a separate Shopify payout hitting your bank account on a delay, co-packer invoices coming in net-30 that your bookkeeper hasn't touched yet, and a Plaid transaction labeled 'ACH DEBIT' that could be your 3PL or your label printer lease. Every month you spend 2-3 hours reconciling this into a Google Sheet before you can answer the one question your investors and your gut both need: how many months of cash do I actually have? And that number is stale the moment you close the laptop.
What you'll set up
Apps, data, and prompts
The combination of Starch apps, the data sources they pull from, and the prompts you use to drive them.
Starch syncs your Stripe data and your Plaid bank transactions on a schedule — charges, payouts, and categorized expense data flow in daily without manual uploads. The Runway Analysis and Scenario Analysis apps read from that synced data directly, so your dashboard reflects actual cash movement rather than a snapshot you pulled last Tuesday.

The founder opened Runway Analysis on a Tuesday morning without doing any prep. Stripe showed $62k in DTC charges for the trailing 30 days; Plaid showed $18k from a Shopify payout and $41k in wholesale receipts hitting the operating account. Gross cash in: $121k. Gross cash out: $159.2k, for a net burn of $38.2k — but that included a $74k co-packer run that only happens every 6-8 weeks. The 6-month historical trend smoothed this out to an average net burn of $28k/month, which Starch surfaced automatically without the founder needing to build the rolling-average formula herself. At $287k in the bank, true runway was 10.3 months. She then ran two scenarios in Scenario Analysis: Scenario A added a $22k/month dedicated brokerage retainer starting in September to expand into a new region; Scenario B assumed the retainer plus a 12% lift in reorder velocity by month 4. Scenario A cut runway to 7.1 months. Scenario B brought it back to 9.4. The break-even analysis showed she needed the velocity lift within 90 days of the retainer starting or she'd be fundraising from a worse position than today. That was the actual meeting agenda for the following week — not a number she'd spent two hours computing.

My co-packer invoices aren't in Stripe — they're ACH debits straight from my bank. Will those show up in the burn calculation?
I have Shopify payouts going to the bank and Stripe for DTC. Do I end up double-counting revenue?
Is this the same as what my accountant produces at month-end?
Is Starch SOC 2 Type II certified? I'm connecting my bank account.
My revenue is lumpy — big wholesale POs every quarter, not smooth monthly DTC. Will the runway model handle that?
Can I connect QuickBooks instead of Plaid if my bookkeeper is already maintaining the books there?
