Your starting prompt.

Build a thirteen-week cash flow forecast starting [week]. Combine expected collections, payables, payroll, taxes and other scheduled commitments into weekly receipts, payments and ending cash. Add an alternative collection-delay scenario of [days]. Show missing payment dates and the assumptions used to fill them for review. Identify weeks below [cash threshold] without assuming new borrowing or accelerating receipts automatically.

Copy this starting point, then replace the placeholders with your own inputs.

Method and review

Keep the assumptions visible.

Start with opening cash and dated receipts and payments. Separate recorded cash movements from forecasts, and show which assumptions change the result.

For this task, check

Expected collection dates should reflect customer payment behavior rather than invoice due dates alone.

Synthetic illustrative example

See the method in practice.

Synthetic input. Illustrative output checked locally; this is not a live Proforma run or customer result. Opening cash $120,000. Each grouped row supplies identical weekly flows for that range; four checkpoint weeks are shown.

These invented records explain the method. They are not a recorded Proforma run.

5–8$12,000$16,000
9–12$15,000$14,000
13$18,000$20,000
Illustrative output · from the sample
CheckpointEnding cash$90,000 floor
Week 4$100,000Above floor
Week 8$84,000Below floor
Week 12$88,000Below floor
Week 13$86,000Below floor

Method

Roll each of 13 weeks forward: ending cash = prior ending cash + expected receipts − payments. The displayed rows are checkpoints, not the full weekly ledger. These synthetic dates assume on-time collections; no borrowing is included.

What the result tells you

The lowest weekly cash is $84,000 at week 8. The $90,000 floor is breached from week 7 onward in this projection. Delayed collections require a separate scenario, not an automatic acceleration of receipts.
