Ask anyone, "Who is the biggest ecommerce retailer on earth?" and the answer is likely to be Amazon.

What many peopledon'trealize, though, is that,according to Statista, more than half of Amazon's product sales come via independent third-party sellers. Third-party sellers receive more orders through Amazon's marketplace than: 1) either fulfill the orders themselves (via the Merchant Fulfillment Network, or MFN) or, 2) have Amazon handle logistics and fulfillment on their behalf (viaFulfillment by Amazon, or FBA).

Much debateexists as to which fulfillment option most benefits sellers. But whatever the answer, Amazon is hardly hurting: With either model, it takes a percentage of sales and other fees in exchange for allowing merchants to sell on its marketplace.

Withclose to $60 million worthof products sold by third-party sellers last year (as reported by DC360 above), a thriving software ecosystem has sprung up, dedicated to optimizing third-party sales through Amazon and maximizing efficiency and profits.

And, Amazon certainly recognizes the importance of its third-party marketplace. Currently, it is in theearly stages of launching the Marketplace Developer Council(MDC), bringing the best marketplace app developers together in an effort to better serve its third-party seller community.

Here are seven such top marketplace apps third-party merchants should consider using to grow their bottom line.

Ignite by SellerLabs:A charter member of the MDC council, SellerLabs was born like many great startups when its founder Brandon Checketts had a pain point he needed to eliminate in his marketplace business.

This resulted in the first Seller Labs product,Feedback Genius, which automates buyer-seller communication in product reviews. SellerLabs now offers a suite of marketplace apps, including Ignite.

Like Google, Amazon has its own version of paid and organic search. Amazon's Pay-Per-Click (PPC) option is namedSponsored Products. As with Google Adwords, a business owner bids on keywords and pays a fee when a user is directed to his or her product through Sponsored Products.

The primary metric for measuring the success of a Sponsored Product campaign isAdvertising Cost of Sale (ACOS). Ignite's seamless integration with Amazon's advertisingAPIenables greatly enhanced analytics and reporting capabilities, and it retains all historical data, whereasSeller Centralretains data for 60 days. Ignite helps automate businesses' campaigns by offering decisions based on historical data.

Ignite can schedule ads to run at specific times of day and provides keyword suggestions and competitor analysis. Here is acase studyon how Ignite dramatically reducedQuiverrjavascript:void(0)'s ACoS.

Automated pricing

Feedvisor.If you're a regular Amazon shopper, you've undoubtedly noticed that prices for specific products fluctuate often -- sometimes even multiple times in a day. With such intense competition, often for identical products, sellers are always looking for a competitive edge. Feedvisor harnesses the power of machine learning, crunching millions of data points to automatically adjust your pricing, optimizing it for competitiveness and profitability. ANew York Timesarticle notedthat Feedvisor increased sales by 15 to 40 percent.

Feedvisor'sRevenue Intelligencecomponent harnesses similar technology to help businesses make informed, up-to-the-minute inventory decisions, helping to ensure they're not losing sales due to items being out of stock.

Accounting and taxes

TaxJar.在早期的电子商务,美国商人回答e spared the burden of collecting sales tax on orders shipped outside the state where they were located. For Amazon, this acted as an additional selling point, particularly on high-ticket items in states with high sales taxes, like New York.

Customers there would essentially receive a discount in excess of 8 percent by purchasing from Amazon rather than a local store. Before long, state governments began to protest this loss of tax revenue vociferously; accordingly,Amazon began to collect state sales taxin all states that levy one.

While it isstill a gray areawhether third-party marketplace sellers are obligated to collect sales tax in states where they don't have asales tax nexus,他们是under increasing pressureto do so in the future. This is particularly true for Fulfillment by Amazon sellers, who may not be aware where Amazon is fulfilling their orders from, potentially making them liable to collect sales tax. With this in mind, many third-party sellers are proactively opting to collect sales tax across the board.

Arguably more detrimental than increased prices for consumers to third-party sellers is the potentially tremendous burden of collecting taxes of varying rates and filing returns in over 40 states in order to achieve full compliance. That's where TaxJar comes in.

TaxJar automates the process of collecting the appropriate taxes when orders are placed, and even files all of the necessary paperwork and returns automatically. The amount of administrative headaches this saves, coupled with the assurance that a business is living up to its tax obligations, makes TaxJar a must-have app for marketplace sellers.
