Marketplace services for Amazon sellers, explained in full.

What the service entails

Account Management is a managed-operations service for Amazon.in sellers. A named account manager, supported by our cataloging, advertising and compliance staff, performs the recurring Seller Central work for your account: order and inventory monitoring, buyer communication within Amazon's policies, promotions, account-health monitoring and weekly reporting.

Work is performed inside your own Seller Central account using the secondary-user permissions you grant to Calium (Seller Central > Settings > User Permissions). You remain the account owner; we never ask for your primary login credentials. Access is scoped to the roles the service needs and is removed when the engagement ends.

What the service entails

Advertising Optimization is the planning, launch and continuous management of Amazon Ads campaigns for Amazon.in sellers. We work inside your Amazon Ads console using the access you grant us, so spend, campaigns and reports always remain in your account.

Deliverables are defined in writing at the start of the engagement: a campaign architecture (Automatic for discovery, Broad/Phrase for research, Exact for harvesting proven terms, Product Targeting for defence), a target ACoS/TACoS agreed with you, and a weekly optimisation routine covering search-term harvesting, negative keywords, bid and placement adjustments, budget pacing and creative refresh for Sponsored Brands.

Advertising Optimization does not include guaranteed sales or ranking outcomes; results depend on product, price, reviews and inventory availability. We report actual spend, sales and ACoS every month against the agreed targets.

What the service entails

Training is an instructor-led service that teaches business owners and their staff how to operate an Amazon.in seller account correctly and in line with Amazon's policies. Sessions are delivered live (video call or in person at our Laxmi Nagar, New Delhi office) in Hindi and English by Calium account managers who run live seller accounts every day.

Training does not require any access to your Seller Central account. Where you prefer hands-on practice, you operate your own account during the session while the trainer guides you on screen. Every programme includes written SOP documents, checklists and 30 days of post-training email/WhatsApp query support.

What the service entails

Cataloging covers the creation, correction and upkeep of product detail pages on Amazon.in. We research buyer keywords, write titles, bullet points and descriptions that follow Amazon's category style guides, prepare images to Amazon's technical specifications and upload catalogs through category flat files or the Add Products workflow.

For Brand Registry sellers we build A+ Content and Brand Stores. We also fix existing catalogs: suppressed listings, variation (parent/child) errors, incorrect browse nodes, duplicate ASINs and image-compliance rejections. A product information (PIM) sheet is maintained as the single source of truth for every SKU.

What the service entails

Taxes covers the Indian tax obligations specific to marketplace selling: GST registration (and additional-place-of-business registrations for FBA warehouses), correct HSN codes and GST rates on every listing, Seller Central tax settings, monthly reconciliation of marketplace settlement reports against TCS (GSTR-8) and TDS (Section 194-O) credits, and preparation support for GSTR-1 / GSTR-3B.

Statutory filings and sign-offs are performed by practising chartered accountants engaged by Calium; Calium prepares the marketplace data, reconciliations and Seller Central configuration.

What the service entails

Account Health & Reinstatement protects the seller account itself. Proactively, we monitor performance metrics and policy notifications and correct issues before they escalate. Reactively, when an account or ASIN is deactivated, we diagnose the root cause, draft a Plan of Action (root cause, corrective actions, preventive measures, evidence) and manage each round of appeal until Amazon responds.

We cannot guarantee reinstatement; Amazon alone decides appeals. We prepare accurate, complete appeals and advise honestly when an appeal is unlikely to succeed.

What the service entails

Imaging covers the production and preparation of product images for Amazon.in listings. We photograph products at our New Delhi studio or process the seller's existing photographs, and deliver image sets that meet Amazon's Product Image Requirements: a main image on a pure white background (RGB 255,255,255) showing only the product for sale, filling at least 85% of the frame, at 1000 pixels or more on the longest side so that zoom is enabled, in JPEG/PNG/TIFF format without text, logos, watermarks or borders.

Secondary images are planned to answer buyer questions: lifestyle/in-use shots, scale references, feature infographics, size charts and packaging images, following the category-specific image guidance (for example apparel on-model or flat-lay rules, and no mannequins where prohibited). Deliverables are supplied named to your SKU/ASIN list so they can be uploaded directly or by our Cataloging team.

What the service entails

A+ Content / Enhanced Brand Content is the design, copywriting and submission of A+ modules for brand-registered ASINs on Amazon.in. A+ Content replaces the plain product description with image-and-text modules (comparison charts, feature banners, brand story) and is available to sellers enrolled in Amazon Brand Registry.

We select modules from Amazon's A+ Content Manager templates, write copy that follows the A+ Content guidelines (no pricing, promotions, time-sensitive claims, competitor references, contact details or unsupported claims), design images to module specifications, and submit the content from your account for Amazon's review. Where Premium A+ is available to the account, we design to Premium module specifications. Brand Story and Brand Store (storefront) design are included options.

What the service entails

Content is the research and writing of the text elements of an Amazon.in product detail page: title, bullet points (key product features), product description and backend search terms, plus attribute values that drive filters and indexing. Copy is written to Amazon's category style guides and listing policies — accurate, free of promotional language, pricing, shipping claims and prohibited claims — and structured around the keywords buyers actually search.

Each deliverable is supplied in an editable sheet mapped to your SKUs, ready for upload by you or by our Cataloging team. For multi-marketplace sellers we adapt the same source content to Flipkart, Meesho, Myntra and JioMart requirements so that product information stays consistent.
