Full Cost Breakdown
| Cost Category | Low | Medium | High | Notes |
|---|---|---|---|---|
| Store Space Lease & Build-Out | $22,800 | $91,200 | $228,000 | A 1,500-2,500 sq ft c-store needs significant refrigeration investment. Walk-in coolers are a meaningful five-figure capital purchase installed. |
| Initial Inventory | $22,800 | $57,000 | $136,800 | Tobacco products and beverages are the highest-volume categories. Maintain 2-3 weeks of fast-moving inventory. |
| POS & Lottery System | $3,420 | $11,400 | $28,500 | Lottery terminals are provided by the state lottery commission. POS integration with fuel pumps requires specialized software. |
| Licenses & Permits | $1,140 | $5,700 | $17,100 | Tobacco retail license fees vary materially by state. Lottery license applications take 30-60 days. |
| Insurance | $2,280 | $7,980 | $22,800 | Convenience stores have high robbery risk — crime/robbery insurance is essential. Premiums scale with neighborhood crime rate and hours of operation. |
| Security System | $3,420 | $9,120 | $22,800 | Comprehensive surveillance is essential for deterrence, robbery documentation, and insurance. Minimum 8-16 cameras. |
| Working Capital Reserve | $11,400 | $28,500 | $68,400 | C-stores have predictable daily cash flow but need reserves for slow initial weeks. |
| Fuel System (if applicable) (optional) | $5,700 | $114,000 | $570,000 | Fuel is optional but dramatically increases revenue. New UST installation with canopy is a multi-hundred-thousand-dollar capital project. Acquiring an existing fuel system reduces this cost considerably. |
| Total Startup Cost | $67,260 | $210,900 | $524,400 | Required costs only |

Common Mistakes to Avoid
- 1
Underestimating the complexity of a fuel system — environmental regulations, insurance, and maintenance are significant
- 2
Buying a store in a low-traffic location — convenience stores live on traffic count and impulse purchases
- 3
Not implementing proper inventory management — shrinkage from theft is a meaningful share of revenue at stores without controls
- 4
Underestimating tobacco and lottery licensing timeline — allow 60-90 days for all permits
- 5
Ignoring the prepared food opportunity — hot food and coffee are the highest-margin items in a c-store
Next Steps to Launch Your Convenience Store
- 1
Form your LLC in Maine — convenience stores sell regulated products (tobacco, alcohol, lottery) and carry significant inventory liability (filing fee: $175)
- 2
Obtain a Maine retail business license and any tobacco retailer license required for selling cigarettes and tobacco products
- 3
Apply for a beer and wine or full liquor license if selling alcohol — Maine ABC licenses can take 30-90 days to process
- 4
Obtain a Maine lottery retailer license if selling lottery tickets — apply through Maine lottery commission
- 5
Get commercial general liability and property insurance; premiums scale with location and operating hours
- 6
Set up a convenience store POS system (Verifone, Gilbarco, or PDI) with tobacco age-verification prompts and lottery ticket scanning
- 7
Establish wholesale accounts with Core-Mark, McLane, or Maine regional C-store distributors for snack, beverage, and tobacco inventory
- 8
Install security cameras covering all aisles, coolers, and the register — theft prevention is critical for high-turnover retail
