If I were in your position, these are the important factors I would assess prior to selecting a platform - alongside some commonly mentioned names as potential solutions.
✔️ Indicator of a Good Global B2B Platform
Verified Buyers / Supplier
Trust is essential. A good platform should verify profiles (business licenses, export charts, testimonials). This is useful for avoiding fake leads or unscrupulous buyers.
Export / International Trade Tools
An example is customs/documents assist, multi-party payments, and shipping/logistics. All together, a quality platform reduces the friction level to trade internationally.
Global Reach with Strong Buyers
You should not settle inside India. You will want buyers in other countries - Middle East, Europe, Africa, etc. Exhibiting your products globally means more exposure = more opportunity.
Good Discovery / SEO / Product Exposure
Simply dropping your products on the platform will not mean anything. Putting them in an area where people are searching (on the platform and search engines) matters. Platforms that assist with keyword features, catalog, and buyer analytic tools cross the board are ideal.
Transaction Costs & Support for SMEs
I am in support of premium features, but the entry (cost / terms / fees) barriers should be accessible enough for small manufacturers too. Also access to information / support from the platform (listing, issues, payment) is very pertinent.
After Sales Features / Services
Once you receive orders, support for issues, spare parts, maintenance, etc. will determine how you are perceived in the marketplace if addressing after sales. A platform that offers follow.
