Quick Answer
E-commerce cash flow problems typically stem from large inventory purchases before sales, platform payout delays (14 days for Amazon), holding GST/HST that must be remitted, and seasonal sales spikes. The solution: a 13-week cash flow forecast updated weekly.
Cash flow — not profitability — kills most small businesses. An e-commerce store can be profitable on paper while running out of cash to buy the next round of inventory. Understanding and managing your cash cycle is essential for sustainable growth.
The E-Commerce Cash Flow Cycle
- You spend cash to buy inventory → your cash decreases
- Inventory sits in your warehouse or FBA centre (cash is tied up)
- Customer places an order → you ship
- Platform collects payment → holds it 1–14 days
- Platform deposits net payout into your bank → cash returns
- You pay GST/HST remittance from that cash → cash out again
The Big Cash Flow Killers
- Amazon's 14-day payout cycle — Your cash is inaccessible for up to 14 days after a sale
- Inventory restocking — You pay for the next order while waiting for the current one to sell
- GST/HST remittances — Easy to spend GST/HST collected before the remittance deadline
- Seasonal inventory buildup — Pre-holiday stocking requires massive upfront cash
Cash Flow Solutions
- Maintain a dedicated GST/HST holding account
- Build a 60-day operating cash reserve
