BookCoversLab
BookCoversLab is a browser-based KDP cover creator built specifically for Amazon KDP authors. It automatically handles trim sizes, bleed, and spine math so you don’t need spreadsheets or manual calculations.
With the built-in KDP cover calculator, BookCoversLab supports all common KDP trim sizes and paper types, and dynamically updates the spine width when you change your page count. Real-time preflight checks validate 300 DPI resolution, CMYK color profile, bleed, and safe zones, helping your cover pass KDP review on the first try.
Authors can start from professional templates based on 10,000+ bestseller covers, or generate unique backgrounds using AI cover generation. You can convert an existing Kindle ebook cover into a full paperback or hardcover wrap in minutes, then export a print-ready PDF/X-1a:2001 file ready for upload to Amazon KDP.
BookCoversLab is ideal for indie authors, small publishers, designers, and KDP beginners.

incentX
incentX is an incentives and compensation platform that runs every incentive program off one spine: the ERP transaction. Sales commissions, rebates, royalties, chargebacks, billbacks, and trade promotions are calculated from the same invoices, orders, and credit memos your finance team closes on.
incentX reads each transaction once and checks it against every active program, so one invoice can drive a rep's commission, a customer's GPO rebate, and a trade promotion at the same time, with one audit trail behind all three. Plans are built in a no-code rule engine, reps and partners see payouts in real time, and customers and vendors submit claims through the Incentive Business Network portal.
Pre-built, two-way connectors cover NetSuite, SAP, Microsoft Dynamics, and Sage, and incentX also connects to Epicor Prophet 21, QuickBooks Online, Salesforce, HubSpot, and Zoho. incentX is SOC 2 Type II certified, and the average customer goes live in six weeks.
