We help businesses organize data flows and prepare information for analytics. This includes designing ingestion and transformation workflows, combining data from business systems, preparing distributed processing jobs and shaping datasets for reporting and analysis.

Our work can include Databricks and PySpark for scalable data processing, Azure Data Factory for orchestrating and scheduling data movement, Microsoft Fabric for connected analytics and data services, and Cosmos DB for applications that need a flexible, globally distributed database. We help map source data, define transformations, document pipelines and build validation steps so teams can understand how information moves and where it comes from.

Projects may connect commerce, POS, ERP, inventory, finance and customer data. We work with your team to identify useful outputs, such as consistent reporting datasets, operational dashboards and cleaner inputs for business intelligence or AI workflows. The design depends on your existing Microsoft and cloud environment, data volumes, access rules and reporting needs.

Explore how we support commerce, retail technology, financial operations and business automation.

Serving New York companies

Business experience that understands New York.

We serve New York companies and businesses across the United States, including apparel brands, accessories companies, retailers, wholesalers and growing e-commerce operations. Our work combines the pace of daily commerce with the reporting, inventory discipline and coordination that management needs.

Our professional experience includes New York businesses such as Eric Javits, Flash Ventures and Yak Pak, alongside our work with Gretchen Scott Designs. We understand how finance, merchandising, marketing, customer service, technology and warehouse teams depend on one another. We help translate business priorities into practical systems, clear responsibilities and repeatable processes.

Support can focus on a defined project, a system migration, ongoing commerce management or a broader operational improvement plan. We work with owners, executives and internal teams to define scope, prioritize issues and keep implementation aligned with everyday business needs.

Retail & point of sale

Connect the store with the online business.

We work with Shopify POS and Heartland Retail to help businesses coordinate in-store selling with their online operations. A successful retail setup requires more than a checkout screen: product records, locations, inventory, customer information and reporting must follow a consistent operating process.

Our support includes reviewing product and variant structures, SKU and barcode consistency, inventory tracking, store locations, product availability and the relationship between physical stock and online inventory. We help teams organize store workflows, understand reporting and identify mismatches between what staff see at the register and what customers see online.

For Shopify POS, we help align retail operations with Shopify administration and e-commerce workflows. For Heartland Retail, we help assess inventory and catalog configuration and its connection to the online store. Pickup, shipping, returns and transfers are planned around the capabilities and configuration of the selected systems.

Hyperspace & integrations

Make connected systems work together.

Our experience includes Hyperspace and the operational relationship between Heartland Retail and e-commerce platforms. We help investigate product publication, inventory availability, field mappings and synchronization issues so the right information reaches the right destination.

We review how items are identified, which system controls each field and how product eligibility affects online publication. This can include comparing source-system web-selling settings with integration settings, checking missing items and reviewing discrepancies in quantities, prices, variants and product data.

Integration projects begin with a clear source of truth for each data type. We help document the expected flow of products, orders and inventory, test representative items and review exceptions before broader changes. The exact scope depends on the connector, platform configuration and supported integration features.

EDI & wholesale workflows

Bring trading-partner requirements into daily operations.

My experience includes EDI setup and business-system projects. We understand that electronic data interchange must connect with the people and processes responsible for wholesale orders, inventory, warehouse execution and financial records.

Our work includes coordinating requirements, reviewing data mappings, validating item identifiers and helping teams reconcile information across systems. We support the planning and testing of order, shipment and invoice workflows according to the requirements of the trading partner and the chosen EDI provider.

We help establish responsibilities for reviewing rejected documents, incomplete information and processing exceptions. Connecting EDI to ERP and operational workflows helps reduce duplicate entry and makes it easier to follow a transaction from the original order through fulfillment and accounting.

AI automation

Build useful automation around real work.

We apply AI to software development, SQL analysis, documentation, product content, SEO, reporting and operational process improvement. We start by identifying repetitive tasks, the information they require and the decisions that should remain with a person.

For commerce teams, AI can assist with product descriptions, attribute preparation, catalog cleanup, content consistency and marketplace listing drafts. For technical teams, it can support code development, query preparation, troubleshooting summaries and system documentation. For management, it can help organize data and draft explanations of sales, returns and operational trends.

We combine AI-assisted work with scripts, structured data and integrations where appropriate. Each workflow needs defined inputs, output checks and a clear review process. We help teams evaluate results, handle exceptions and document how to use the workflow consistently. Sensitive information and access requirements are considered when selecting tools and designing the process.

Catalogs, marketplaces & inventory

Manage the detail behind every listing.

We help build and maintain product catalogs across Shopify, Amazon and other sales channels. This includes product naming, descriptions, images, categories, attributes, size information and parent-child relationships for products with multiple colors and sizes.

Our work connects merchandising decisions to operational data: SKU structures, UPCs, inventory availability, pricing and channel-specific requirements. We help prepare imports and exports, identify incomplete listings and compare channel data against source records to find products that are missing or inconsistent.

Amazon support includes Seller Central listing operations and Vendor Central workflows, listing preparation, catalog quality, fulfillment coordination and sales and returns analysis. We also help coordinate product and order data for eBay, Etsy, Walmart and Bonanza. Channel requirements vary, so we review each marketplace’s available integration path, data fields, identifiers and operating workflow before planning a connection. Shopify support covers retail and wholesale product structures, collections, navigation, product information and the processes that keep the storefront current. We review results in the context of the business rather than treating catalog uploads as isolated tasks.

Financial visibility

Understand what growth means for the business.

Maiservice helps businesses connect commercial activity with the financial information needed to understand performance, improve reporting and support better operational decisions.

We help organize monthly reporting, compare budgets with actual results and examine the relationship between sales, returns, inventory, operating expenses and margins. Account reconciliation, consistent reporting definitions and clear responsibilities support more reliable management information.

Our business intelligence work includes SQL reports, dashboards, structured exports and executive summaries. We help distinguish revenue growth from the operating factors that influence profitability, giving decision-makers a more useful view of channels, products and business processes.

Ongoing technology & operations

Support the systems your team relies on.

We provide hands-on help with websites, enterprise databases, cloud infrastructure, file transfers and everyday technical operations. Our experience spans PHP, SQL, PowerShell, Windows Server, Linux, FreeBSD and cloud services, including AWS storage and transfer workflows.

Projects may include database design, reporting queries, backup and recovery planning, server administration, data imports, integration scripts and troubleshooting. We also help document workflows so recurring work is easier to understand, maintain and hand over.

We coordinate with internal teams and service providers to resolve issues in context. Whether a problem starts with a product record, a website, an integration or a report, our goal is to understand its business impact, identify the cause and implement a maintainable improvement.
