Instagram shop vs your own store

The short answer

Instagram sells what photographs well to an audience you rent; your own store sells everything to an audience you own. The catalog feeds both from one table - the mistake is building only on rented land.

How to actually decide

• Where do repeat buyers come back to?
• Does your product need more than a caption to sell?
• Checkout control: payment mix, COD, shipping logic.

What we recommend

Feed discipline wins either way - one clean product table feeding both surfaces. Both sides of this comparison are builds we deliver - which is exactly why the recommendation above has no sales angle. Itemise your stack in the ecommerce development, or store cost.
