How to build a 13-week cash flow forecast as Property Management Founders
Your 13-week cash flow forecast probably lives in a Google Sheet or Excel file that someone on your team updates every Monday by logging into AppFolio, exporting the rent roll, cross-referencing against your Plaid or bank statement for trust account activity, then manually keying in expected maintenance vendor payments and owner distribution dates. One missed late-pay, one surprise HVAC repair, or one owner pulling funds early and the whole model is wrong before lunch. You're running on a 2-week-old snapshot and guessing at the next 90 days on a portfolio that might have 150–400 units across multiple entities, each with its own trust and operating account.
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 connects directly to Plaid on a scheduled sync — your trust account and operating account transactions and balances refresh daily and are stored in Starch's database. AppFolio, Buildium, Propertyware, and Rent Manager are reachable through browser automation — no API needed — so Starch can pull your current rent roll, lease expirations, and open work order costs to feed into the forecast. QuickBooks, if you use it for your management company books, syncs on a schedule as well and contributes vendor payment history.

On Monday March 3, Starch's Runway Analysis dashboard shows $187,400 in the trust account and $41,500 in the operating account. Plaid confirmed both balances at 6 AM. The rent roll from AppFolio (pulled via browser automation Sunday night) shows 220 leases at an average $973/month — $214,060 total monthly roll. Starch projects $171,200 arriving in the trust account by March 7 based on the 80% early-week collection curve you configured. Owner distributions of $148,600 go out on March 5 via ACH. After the management fee transfer of $18,800, landscaping ACH of $3,800, and the HVAC draw of $4,200 for unit 14B that came in as an approved work order, the trust account closes the week at $183,200 — healthy. The operating account absorbs the management fee inflow, pays a $11,400 payroll run on March 7, and closes the week at $47,000. Transaction Insights flagged one anomaly mid-week: the HVAC vendor charged $4,200 against a 90-day average of $890. Starch surfaced it Tuesday morning in Slack so you could confirm it was the approved work order before worrying. The Scenario Analysis tab shows that if delinquency jumps from the current 2.1% to 7% starting April 1 — the rate you saw during your worst COVID month — operating account runway drops from 14 weeks to 9 weeks, and you would need to either delay one owner distribution cycle or draw on your line of credit by week 11.

My trust account holds owner funds — will Starch mix that up with my operating cash?
I use AppFolio but AppFolio doesn't have a public API. Can Starch still pull my rent roll?
Is this SOC 2 certified? My property owners sometimes ask about data security.
Can I track cash flow separately for each property or each owner entity?
I have QuickBooks for my management company but not for the trust accounts. Does that cause a gap?
What happens if a vendor payment clears at an unexpected time and throws off the weekly projection?
Can I share the forecast with my CPA or a part-time CFO without giving them bank login access?
