Yep. The problem becomes more acute if you have more typical numbers like a customer lifetime value at, say, $3k over 2 years and a cost of acquisition at $1k. That's a very worthwhile business but going cashflow negative for the first ~8 months of the relationship can get very unfun.

If you were actually at $10 CACA and $10 monthly revenue you'd give a phone call to either a) Bank of America credit card customer service (ask for a $25k++ credit limit) or b) your advertising channel (and ask for Net 30 payment terms).
